wefalck got a reaction from AON in pin vise and drill bits
When looking for tools keep in mind that model shops often have the bad habit of selling cheap stuff at elevated prices to unsuspecting fellow modellers. Most fine tools are not made for us, but are adopted from various trades, such as watchmaking, surgery, dental care, luthiers etc. In the age of Internet, global trade (my sympathy to our US American colleagues) and supply chains, there is no reason not to look for the real source of such tools. Just do a search when you discover a tool and the search engines or auction platforms usually propose a wide selection.
It is also a good idea to browse the (on-line) catalogues of the above mentioned trades to get an idea for what tools are available and what their price range may be (attention: medical stuff may be expensive, but often you can find 'seconds' on the Internet at lower prices that are good enough for our uses).
I not normally use a pin-vise for drilling, there are tiny single- or double-action Archimedean drills for watchmakers that do a better job and clamp down to 0.1 mm, if you get a good one.
I gather there are four types of pin-vises on the market: the all-steel toolmaker ones with knurled bodies, the slender watchmaker ones with steel jaws, but often a fluted brass body, the watchmaker ones with exchangeable collets (not sure what the point is, it is better to have a set of pin-vises handy), and the biological ones that are steel, but have a fluted ebenony handle. In addition, you get the cheap modeller ones with brass jaws and/or eloxated aluminium bodies.
The larger toolmaker ones (e.g. Starret or Eclipse) are bored 2.5 mm, so can hold the common burrs and other tools with the same 2.4 mm shaft diameter, such as triangular scrapers etc., which could be useful for deburring and other tasks. Not sure whether there are pin-vises bored for 1/8" for the Dremel bits.
I posted the picture below before, but it can give you an idea of what is on the new and second-hand market:
1 - Archimedes drill for watchmakers.
2 - Slender modern pin-vice with hollow fluted brass body.
3 - Slender antique pin-vice with hollow fluted brass body.
4 - Shop-made pin-vice with walnut body and head made from an insert drill-chuck; these drill-chucks are unfit for their intended purpose as they usually do not run true.
5 - Eclipse toolmaker's pin-vice with knurled steel body; these come in different sizes.
6 - French-style pin-vice; these are closed with the sliding ring and have usually brass inserts in the two jaws that can be adapted to special needs;
7 - Dito, here the jaws are replaced in hardwood for delicate parts.
8 - Antique laboratory pin-vice with fluted wooden handle.
9 - Modern pin-vice with fluted wooden handle; these come in different sizes and capacities.
10 - Antique toolmaker's pin-vice for very delicate work in confined spaces.

Fitting the deck
The deck is made from 0.4 mm thick Bakelite-paper. I find it easier to engrave the deck-seams consistently into this harder material with my tools, then into the softer styrene sheet. Perhaps I should get some day one of those hooked engraving tools the plastic modellers use (I have the suspicion these are the same tools as dentists use to scrape of ‘plaque’ – I have one of those and perhaps should have tried).
I first printed out the deck-drawing, cut out the shape and fitted it to the ship. Using the paper template, the shape was cut from the Bakelite with a small margin. This then was fitted very carefully in an evening’s session. Fitting started from the stern working forward, taking off material with a diamond nail-file while checking the fit after a couple of strokes.
A tight fit is important, as the whole idea is to paint the deck off-ship to avoid a complex masking exercise. Also, the painting process (as described in the build-log for SMS WESPE) would be difficult to exercise within the constraints of the bulwark.
Tools used for engraving the deck seams
The fitted deck was taped to a printout of the deck with the planks marked as guidance for engraving. A heavy steel ruler ensured straight lines. First, the plank seam was marked with a scalpel to provide some ‘tooth’ for the graver. Then a narrow engraver’s graver was run twice along the ‘seam’ to clean out the shallow groove. Once the engraving was completed, the whole deck was thoroughly brushed with a rotary bristle-brush to remove burrs.
I ended up doing this three times, as in the first two attempts I lost count and cut a skewed seam. This is unrepairable, so I had to start all over again. However, the first fitted deck provided a good template, speeding up the fitting process: after scoring the material with a scalpel around the edges of the template, one can break the new deck out of the bakelite sheet. Only comparatively little fitting was required then.
In fact, scoring the bakelite-paper with a scalpel twice and then breaking along the line is a quick and clean way of getting straight cuts that just require a bit of sanding with a diamond file.
The next step would be to cut out the openings for the companionways and hatches. However, these have to be tight fits to them and it will be easier to first build those and then file out the openings – back to the drawing-board for some time.
To be continued …

wefalck reacted to Dr PR in pin vise and drill bits
1. If you will be using a hand held pin vise DO NOT get carbide bits. They are very brittle and break with the slightest twist. These are for use in milling machines, drill presses and PC board fabrication machines. High speed steel bits are good for pin vises.
Most of the bits I have seen with thick shafts and narrow cutting ends are carbide and are designed for automatic drilling machines.
2. Whatever you get, be sure it will hold the smallest bits (#80, 0.0135 inch, 0.34 mm). I have two of the types with removable collets and they will not hold the tiny bits.
I bought a set of four pin vises with the "collet" as part of the body. The smallest closes down to virtually zero diameter and holds the smallest drill bits tightly. The handle is a simple knurled cylindrical shaft that can be chucked into a drill press. The handle is hollow, and allows long bits, wires, needles, whatever, to be held by the pin vise. I don't recall where I got them, but the set wasn't very expensive. Almost certainly made in China.
3. These things are useful for holding anything small. In addition to drill bits I have used them to hold needles, pieces of wire with hooks in the end to help with rigging, and short pieces of jeweler's saw blades. Here is a photo of the smallest pin vise holding a piece of a jeweler's saw. I needed to make a cut with a very narrow kerf.
Having multiple pin vises means you can use one to hold the thing you are working on and another to hold the tool you are using. Or you can have multiple sizes of drill bits ready to use without changing collets.
4. The only drawback I have found with the hollow tube handle pin vises is that they do not have a finger rest on the end of the handle - just the end of the hollow tube. This is a bit uncomfortable when using a finger to press the tool as you are turning it to drill holes. I have thought about making one - perhaps adapting the rotating finger rest from one of my other pin vises that has multiple collets. Bit this hasn't been a big problem.

Thanks for your comments @mcb!
It is actually the 'old' duroplastic material invented by Baekelundt. It is essentially one or more layers of paper soaked in phenolic resin and cured between steel plates to ensure uniform thickness and a mirror-like surface.
It is still used for electrical insulation and certain types of PCBs, a class called FR-2: https://en.wikipedia.org/wiki/FR-2.
It is available from thicknesses from 0.1 mm up to 6 mm or even in blocks and rods (usually with cotton-fabric, rather than paper). I got a life-time supply about 30 years ago from a specialised dealer in Berlin, who sold it by the meter.
You can find suppliers on the Internet (including on ebay). Most of the material seems to be produced in India and China these days.
It glues very well with CA - some 25 years ago a made little clinkered boat with bakelite-paper planks glued with CA and it still looks pristine. For larger flat pieces I also used zapon-varnish, which adheres well.
The edges of the bakelite-paper are quite brittle, so care and sharp tools are needed, when cutting it. It sands well with fine diamond nail-files.

Oops, missed the continuation of this new project ... have been travelling too much the last few weeks.
When I used very thin copper-sheet to simulate hull plating and pouncing the rivets, I found that rubbing them down from the front with a cork (Champagne corks work best, because of their round lower edges and sort of integrated handle) reduces the distortion of the sheet and gives a more realistic look. I have not tried the same with styrene sheet. Not sure that it would work, because it is less malleable than copper, but it may be worth a try.
Another material that I have used is this self-adhesive aluminium tape that is used to cover up the seams in dry-walling. However, I have used it only only represent rivetted reenforcement strips, not larger surfaces, as I am a bit weary of self-adhesive materials - the adhesive film might dry out and become brittle with time.

Fitting the rails
The rails are 0.75 mm x 1.50 mm styrene strips on top of the bulwark and a 0.75 mm x 2.00 mm strip over the stern. The edges of the strips are rounded.
To this end I cut a scraper from a piece of razor-blade which is held in a short pin-vice. The strip is held in a simple jig made from cardboard. Strips of cardboard were cut with clean and vertical edges and glued to a cardboard-base so that styrene strips of 0.25 mm, 0.50, and 0.75 mm thickness can be wedged into the resulting notch, holding it straight and vertical.
In this way a clean and uniform profile of the styrene strip can be achieved quickly.
The styrene strips then were pre-bend, holding them lightly in round-nosed pliers and by ‘massaging’ them around my thumb to make them conform to the sheer-line as closely as possible. They then were glued onto the stanchions and the top bulwark strake using styrene-cement.
As can be seen from the cross-section shown in the previous post, the profile of the rail may be even more sophisticated with some cornice planed in. I simulated this my lacquering a 0.1 mm copper wire into the outboard corner under the rail.
The next step will be puttying up any small gaps that have developed during the planking process.
As one can see on the pictures, I also started to work on the deck by making a paper template for it.

Planking the bulwarks
The planking of the bulwarks follows the same procedure as that for the hull, but had to be handled much more careful, as the inside will be visible and there will by no adjustments possible by sanding or scraping. The main reason for the latter is, that the planks are of scale thickness (0.25 mm) and profiled.
Section through a bulwark drawn by Friis-Pedersen (1980).
As can be seen from the two images above and below, it was not uncommon to give the edges of the planks a decorative profile by using an appropriate profile plane.
Bulwark of a Swedish jagt, photographed in November 2023 in Stockholm
I had been exploring various ideas for creating these profiles on tiny 1 mm x 0.25 mm styrene ‘planks’ uniformly and consistently close to the edges. In the end I decided on a simple and rather makeshift solution: a steel ruler was taped to a small cutting-mat to serve as guide for the very flexible strips. The chosen tool is an old-style ruling pen, of which I have several knocking about in my drawer of draughting utensils. This was set so that it creates a groove close to the opposite edge, when run along the edge of the strip. This works only for strips of uniform width.
It was important to prevent the styrene strips from softening too much during gluing, therefore only tiny drops of liquid styrene cement were applied to each stanchion.
Somehow the alignment of the bulkheads was not as perfect as I was hoping for, resulting in some bulges. I hope I will be able to correct/hide this somehow.
Another problem is that the styrene strips of scale thickness are rather floppy, so that edge-alignment is rather difficult. I hope that I can also sort this out.
Once the planks were on, I installed the hawse-timbers between the stem and the cant-frames in the bow.
Next on will be the rails.

Fitting the deck
The deck is made from 0.4 mm thick Bakelite-paper. I find it easier to engrave the deck-seams consistently into this harder material with my tools, then into the softer styrene sheet. Perhaps I should get some day one of those hooked engraving tools the plastic modellers use (I have the suspicion these are the same tools as dentists use to scrape of ‘plaque’ – I have one of those and perhaps should have tried).
I first printed out the deck-drawing, cut out the shape and fitted it to the ship. Using the paper template, the shape was cut from the Bakelite with a small margin. This then was fitted very carefully in an evening’s session. Fitting started from the stern working forward, taking off material with a diamond nail-file while checking the fit after a couple of strokes.
A tight fit is important, as the whole idea is to paint the deck off-ship to avoid a complex masking exercise. Also, the painting process (as described in the build-log for SMS WESPE) would be difficult to exercise within the constraints of the bulwark.
Tools used for engraving the deck seams
The fitted deck was taped to a printout of the deck with the planks marked as guidance for engraving. A heavy steel ruler ensured straight lines. First, the plank seam was marked with a scalpel to provide some ‘tooth’ for the graver. Then a narrow engraver’s graver was run twice along the ‘seam’ to clean out the shallow groove. Once the engraving was completed, the whole deck was thoroughly brushed with a rotary bristle-brush to remove burrs.
I ended up doing this three times, as in the first two attempts I lost count and cut a skewed seam. This is unrepairable, so I had to start all over again. However, the first fitted deck provided a good template, speeding up the fitting process: after scoring the material with a scalpel around the edges of the template, one can break the new deck out of the bakelite sheet. Only comparatively little fitting was required then.
In fact, scoring the bakelite-paper with a scalpel twice and then breaking along the line is a quick and clean way of getting straight cuts that just require a bit of sanding with a diamond file.
The next step would be to cut out the openings for the companionways and hatches. However, these have to be tight fits to them and it will be easier to first build those and then file out the openings – back to the drawing-board for some time.

Thanks ... the Bakelite-paper is semi-transparent, so that indeed parts underneath are shining through. After painting (eventually), nothing will be seen anymore.

Slow Progress (as usual)
The run of the planking and their layout will be determined by three structural members, namely the rail on the bulwark as upper edge, the covering board, which marks the lower edge of the bulwark and the upper edge of which is marked in the original drawings, and the wales, the upper edge of which are also marked in the original drawings.
In order to physically define the top edge of the covering board, the waterways have to be installed first. The consist of a 1 mm x 1 mm styrene strip running along the inside of the bulwark stanchions. This is thicker than the actual water ways would be, but the thickness includes that of the covering board inside the bulwark stanchions. The space between the stanchions was filled with small pieces of 1 mm x 1.5 mm styrene strip. This is a tad wider than needed, but allows me to sand them down to the actual profile outside of the stanchions. While in theory the stanchions are spaced equidistant, the filling pieces still required a bit of sanding to fit them snuggly.
There are actually many different designs for the waterway/covering board arrangement and not any particular construction method is being followed here. The idea is to give the right visual impression after painting, not to follow prototype construction method. In fact, it would have been rather difficult to cut out the notches for the stanchions from the styrene strip representing the covering board at these dimensions, as would have been the prototype method.
The arrangement will be completed by a 0.5 mm x 0.75 styrene strip that will be shaped to a half-round profile using a scraper fashioned from a piece of razor-blade and that will be cemented along the upper edge of the covering board.

***********************
Fitting the rails
The rails are 0.75 mm x 1.50 mm styrene strips on top of the bulwark and a 0.75 mm x 2.00 mm strip over the stern. The edges of the strips are rounded.
To this end I cut a scraper from a piece of razor-blade which is held in a short pin-vice. The strip is held in a simple jig made from cardboard. Strips of cardboard were cut with clean and vertical edges and glued to a cardboard-base so that styrene strips of 0.25 mm, 0.50, and 0.75 mm thickness can be wedged into the resulting notch, holding it straight and vertical.
In this way a clean and uniform profile of the styrene strip can be achieved quickly.
The styrene strips then were pre-bend, holding them lightly in round-nosed pliers and by ‘massaging’ them around my thumb to make them conform to the sheer-line as closely as possible. They then were glued onto the stanchions and the top bulwark strake using styrene-cement.
As can be seen from the cross-section shown in the previous post, the profile of the rail may be even more sophisticated with some cornice planed in. I simulated this my lacquering a 0.1 mm copper wire into the outboard corner under the rail.
The next step will be puttying up any small gaps that have developed during the planking process.
As one can see on the pictures, I also started to work on the deck by making a paper template for it.

So, here it is ...
Planking the hull
In principle planking this hull with styrene strips is not very different from planking with strips of wood. The styrene strips have the advantage that they can be more easily bent across the breadth. One can also shape them like metal by stretching and compressing until they conform to the shape of the solid hull. A disadvantage is that they are less stiff than wood and easily ‘sag’ in, say in thicknesses of les than 0.5 mm, but it also depends on the distance between the frames.
Planking proceeded up and down from the wales and down from the covering board. The Evergreen styrene strips are sawn from sheets as is evidenced by saw-marks on the narrow sides. This results in slight variations of their width, typically up to 0.1 mm wider for a 1 mm wide strip. This has to be considered, when planning the plank layout.
In the end, I didn’t actually use my new plank-clamp much. It was easier to hold the strips short with the edges upright and to scrape the edge with a scalpel to reduce the width in a controlled fashion. There was not much need to bevel the edges. The styrene cement, of course, softens or dissolves the material, which allows it to be pushed together closely, obviating the need for bevelling at least for material of 0.5 mm thickness or less.
Unlike for woodworking, not many specialised tools are needed. I use a scalpel, the tools that in the old days was used to rub-on lettering comes handy to press on the strips, a large diamond nail-file for thinning down strips, and cutting-tweezers as watchmakers use them for shortening strips to length. The latter have the cutting edge bevelled only on one side, allowing for clean cuts without squashing the material. I also made small scrapers from a piece of razor-blade, held in a pin-vise. Steel-wool of various grades helps to blend-in parts or lightly round edges.
The pictures show the planking after cleaning up by sanding and scraping, but before puttying any gaps that may have occurred. I went for some slight irregularity of the surface, as may be observed in a well-used older wooden ship. This livens up an otherwise somewhat sterile styrene surface.
