Eberhard I see a lot of Meccano at our local auction house. It generally goes for a song as kids these days don't seem to have any enthusiasm for nuts and bolts. I think lego put an end to the Meccano era. I used to have a number 9 set (the second largest) but many years ago my father took it away to play with it. He has been dead for 10 years and I'm not sure what happened to it However I like the idea of making a serving machine from Meccano. You might be able to source more bits for you Marklin set at your local auction. -
Brett - She turned out very well. I enjoyed following

Thank you Richard. Soon i am going to need a lot of blocks. Repetition isn't one of my favourite activities so I though I would start the block production line and then do a few at a time as needed. I always read the block making posts of other MSW members with interest, but in the end I come back to what I know. I am therefor repeating the method that I used for Altair with a few slight improvements. I need 3 sizes of .2" .24" and .28" (5mm 6mm 7mm) overall height. I start with a strip of mahogany and glue on to this a further strip which I accurately slot cut on the table saw. I then glue on a closing strip. I need 3 of these for the 3 sizes required. I then slit off strips with the width being equal to the width of the finished block. I then need to drill an axial hole. For this I made a holding jig with slots accurately cut to take the strips pictured above. This was fixed with double sided tape to the moveable jaw of the machine vice. This arrangement allowed me to accurately and repeatably drill the axial hole. I then made a fixture to hold the strips for sanding. This was just a slot in a piece of wood with 1 mm pins to locate the strips. With the strips mounted the edges of the blocks were rounded using emery paper glued into a circular slot. At this stage the strips were moved back to the mill and the 2 ends were drilled in various configurations to take attachment fittings. From the strips single double or triple blocks can be cut off as required

MAKING EYE'S AND HOOKS
KeithAug replied to Peter6172's topic in Modeling tools and Workshop Equipment
Thank you Mark. I find it difficult to ascertain from the web any specific reference to the minimum diameter and I see many references to mal alignment and other quality issues. I was just wondering whether anyone could recommend a specific make that met the criteria. -
MAKING EYE'S AND HOOKS
KeithAug replied to Peter6172's topic in Modeling tools and Workshop Equipment
Peter, I am wondering how the pliers can be soft enough to file down while being strong enough not to bend when being used? Do you harden them? Perhaps you can explain? Ideally the answer would be to buy hardened conical nosed pliers. However I have not yet found any with very small points to the cones. Most available on the web seem to have cones with a minimum diameter of about 1mm, whereas I would agree that 0.5mm is more useful. Does anyone know of conical nosed pliers with very small tip diameters? -
Eberhard, yes I was aware of that problem, hence my remark about making all the blanks first. The larger piece of stock would be mounted and drilled. The blanks would be inserted into the stock and removed without removing it from the chuck thus retaining concentricity. With your equipment i can see why you favour your method. I was just musing on how I would do it with my equipment. Most of the fun is working out the possibilities - as demonstrated by your thoughts on other options.😊

Yes I had assumed this but I bow to your superior knowledge of the ability of the .2mm shank to resist the cutting forces. However I have an idea that I might try in an idle moment - 1. Drill a .2 mm hole in a spare piece of larger stock - say 2mm. 2, Turn the .2mm shank to length and turn the handle to nominal diameter and length. Then part off or more probably cut off with a jewellers saw. 3. Either soft solder or glue the .2mm shank into hole bored in the larger stock. 4 Finish turn the handle and then heat to break the bond. If I were doing many I think I would make all the blanks first, followed by shaping all the handles. Just for fun I might give it a go on my rather large lathe. But not soon as I don’t have .2mm drills.

Eberhard, Very tricky turning. Did you consider making the pins the other way round with the handle end towards the chuck. If you didi why did you decided on the method you used?

The masts are really attractive and very cleanly made. Excellent work.

She has quite an attractive rear, do you know if it severed a particular purpose? -
Jon - I find that for jobs like this rip stop tape works really well. Being self adhesive it is easy to work with and it take colour really well - either from acrylic paint or even permanent markers. I find painting before application is easier as it produces really clean edges. Being a fabric tape it retains some texture even when painted giving it a realistic canvas effect.

Roger - agreed I have never used the Lazy Guy arrangement. For the record Germania will be rigged with the beak facing upward.
-
Veszett, I think I am back where I started and that is upward and downward facing both have advantages and disadvantages. This is also on the net under "how to rig a spinnaker" and shows the jaws facing downward.
-
I thought i had better look up what the internet says about the orientation of the spinnaker pole beak:- Whisker poles should be flown with the jaws facing down. When taking down a whisker pole, the jib sheet usually wants to drop down-and-out of the end fitting. Spinnaker poles are flown jaws facing up, as the spinnaker sheets usually want to lift up-and-out of the end fitting.
-
Roger My recollection of what the French crew did was as follows:- The boat started to broach. A crew member released the spinnaker sheet to recover from the broach. The sheet ran out completely leaving the spinnaker flying like a giant flag. The crew then tried to take the spinnaker down by lowering the spinnaker halyard. With no ability to control the sail it inevitably ended up in the sea and then disintegrated. Veszett, thank you - I'm sure your expertise vastly outweighs mine.
-
Thank you Tom I had thought that might be the case. The spinnaker pole will be positioned vertically in front of the fore mast. Ready for use.
-
Michael - I could wind one. It would only have to be 1mm OD - that's the size of the wire used to make the latch.

Roger, Thank you for reminding me Roger. I remember sailing off the north coast of Guernsey . The (French) boat ahead was flying a spinnaker but we though the conditions were a bit too variable and didn't have ours up. One particularly violent gust panicked the French crew who dropped the spinnaker to avoid a broach. Unfortunately the crew weren't quite ready and as we sailed past the spinnaker disappeared below the hull. A few moments later about half of it reappeared on the the other side of the boat still attached to the sheets. The remainder was presumably wrapped around the keel. They looked very crest fallen. On another point do you recall whether the beak on the end of the spinnaker boom generally faces up or down. I can see advantages and disadvantages with both up and down orientation, but i just can't remember how we used to do it? Thank you Keith, But i will need a wide angle lens. Eberhard, thank you. I suspect it will look less blingy in a couple of years time.

Very nicely done, you must do a build log next time.

Thank you Phil / Mark I will take on board your comments. I have now made the fore and main masts, the fore and main top masts, the fore and main booms and the fore and main gaffs. None of them are actually complete as sundry strops and sheaves have to be added. That left 3 more spars to be made i.e. the spinnaker boom and the 2 main top sail spars. I started with the spinnaker boom which was turned to diameter and then tapered each end by sanding it in the lathe. Turning down long thin dowels requires the support of a steady. Rather than mount the steady I improvised by putting a piece of wood in the back of the tool post. I then mounted a drill in the chuck and bored a hole in the wood slightly larger than the required boom diameter. I then turned the boom to size using this arrangement. I the proceeded to make the gooseneck fitting for the boom. The boom part of the hinge was much the same as previously described. I then discovered a problem. The mast bracket was of insufficient width. This meant that the boom fowled the mast hoops when in the vertical stowed position. I had to remake this. I then needed to make the beak. I don't have any details of this so I used a typical example from and internet search. The latch doesn't work. I then made the topsail spars. These are simple tapered dowels with end fittings and eyes. That's about it for the masts spars and booms, at least for the moment. Now on to something else - a change is as good as a rest.

Hakan - You do remarkably well, i admire your fortitude.

Interesting - more "suck it and see" than I might have expected.

I wish i had learned CAD. Too late now though for this old dog. It hurts my head trying to work out what they are doing?
