Bob Cleek reacted to druxey in Question about the planking
Did you line out the run of planking before you started? That could also be a factor in the planks not lying nicely on the frames or bulkheads.

Bob Cleek reacted to Kevin Kenny in Restoration of the Emma C Berry by Tom Lauria
A wonderful professionally prepared video on the restoration of a model of the Emma C Berry. Well worth watching.

Bob Cleek reacted to Charles Green in Dust on models.
To be brief:
All woods outgas acetic acid fumes. The normal process of organic decay produces it. Oak and bass wood are at the top of the list.
All PVA wood glues outgas the same fumes as does common acrylic.
All nut/seed finishing oils do the same.
Ventilation is a must for enclosed displays.
Display cabinets with glass or special, non-outgassing acrylic glazing are to be preferred.
The only glue that does not outgas acetic acid fumes and is strong enough for assemblies is hide glue. The only finish that is safe is shellac.
For items kept in storage, museums have resorted to powder-coated steel.

Bob Cleek got a reaction from BETAQDAVE in a drafting tool or paper weight
I've been told there are still things that ducks and battens do that can't be done on a screen, particularly on large drawings. I bet you'll find a use for them within a week of getting rid of them. Isn't that always the way it goes?

Not coincidental at all. "Getting your ducks in a row" is a direct reference to fairing a line with a batten and ducks.

Bob Cleek got a reaction from Canute in 48th Scale imperial rulers. Where?
You'd get your hand slapped for doing that in an old-school apprentice training program. In professional practice, measurements are never lifted from the drawomgs. (Many plans bear the notation, "Do not measure from drawings.") The distance notation on the plan is taken off an accurate rule with dividers and transferred to the workpiece using dividers. Even in modeling practice where one might be tempted to "cheat," with 1;1 plans, the better practice is to use dividers to take the distance from a plan, rather than using a rule. This insures accuracy. With a sharp eye and a good rule, measurement can be laid out far more accurately than by measuring from the plans with a rule. (Which is why good machinists' rules and dividers aren't cheap.)

Look for some drafting scale rules on eBay. They come in all scales and "quarter-inch" is pretty common. In the U.S., triangular scales as pictured above commonly have a "quarter-inch" scale on one side. I've never seen one here with a combination of Imperial and Metric, although some engineer's scales (as opposed to architects' scales) will have inches divided into tenth's.
Alternately, 1:48 scale is equivalent to "O" gauge model railroad scale. You should be able to find a 1:48 scale rule offered for sale on a model railroading website.

Bob Cleek got a reaction from uss frolick in Avocado tree wood at all useful for our purposes?
I've read that it's a good tone wood for lutherie, but not widely used for that because of its lack of reliable availability. It's considered a good wood for fine carving.

Because running rigging "runs," and moves, the "bitter end" always has to be tied off to something. It's belayed to belaying pins, generally, during the period after which belaying pins came into use, but also sometimes to cleats and cavels and occasionally posts. Standing rigging is generally fastened permanently, shrouds at their lower ends to chain plates or sometimes pad eyes on deck and to bowsprit irons. There really aren't hard and fast rules, though. There are many different rigging arrangements which can vary from ship to ship, and even vary on the same ship from time to time in the ship's life.
Standing rigging did not go to Samson posts, actually. Samson posts are for towing the ship or making an anchor cable fast when the anchor is set, or to belay mooring lines when alongside a wharf or quay. Here again, things can vary from ship to ship and time to time. You really can't say for sure what general rigging practices were without specifying the type of vessel, it's nationality, and the time in history that's applicable.

Here’s mine. I cast them in a homemade sand mold in 1965. I still use them as I do not use CAD. Splines are ripped from straight grained spruce left over from wood canvas canoe restoration projects.

As shown in the 1st picture they are great weights for ship modeling. I cast mine at Webb Institute in 1961.

Hi John,
I too am in Aus and I happen to have a 12 inch three-sided Imperial rule that includes 1:48. I no longer need this so if you pm me your address I'll send it to you.
Cheers

I have to agree with Harvey, they are most commonly referred to as "Ducks". I know they come in two styles, the one shown above with the hook, and the other has a tab in place of the hook. The "advantage" of the hook is that the "batten" usually used with this style has a groove down the length so that the hook and run/ride inside the groove. Thus enabling you to keep all the ducks on one side, in a row so to speak, because you could "push" or "pull" the batten into place. The tabbed version can only secure the batten in one direction, so depending on the curve you're creating you may have ducks on both sides. They are heavy enough that you could just rest the duck on top of the batten to hold it in place. Back when I was on the board, we had a handful in the department but we used them to hold down the ends of roll size drawings because the battens seemed to disappear over time. No great loss as the department had the most complete set of ships curves I've ever seen. There were dozens upon dozens stored in a slotted, felt lined wooden case. The department head kept them under lock and key and could only be used by those who had proved themselves capable of properly using them. Oh, those were the days.
