This post is start to finish on the next two stern plates, just to give some more detail on how I do it for this model with a frame construction. It starts with the material. A gallon can chopped up.
I use an angle grinder with a 1mm cutting disk to remove the top and bottom and then slice down the welded seam. It cuts easily like a red hot knife through butter. It can be done with shears but the distortion is much more. The rolling pin is just to get the main sheet reasonably flat. I keep the end pieces as they are slightly thicker, 11 thou compared with 9 thou. Doesn’t sound much but they are much tougher to work with yet useful for decking etc.
Apiece is then cut from the main sheet to make the plates. It can be done with shears and scissors but I prefer to use an old office guillotine. It’s only meant for cutting paper but laughs at tin plate. It leaves flat edges and square sections. The picture shows the piece needed on the left.
Strips are then cut of this the width of the plates that are needed. If the plates are butt jointed then they are cut to the size of the plating plan. As my plates overlap they are wider. I only mention this because a couple of times I forgot and just made scrap!
I then stick the plates to a piece of wood with contact adhesive and squeeze them up in a vice. This gets them very flat. One edge of each plate is aligned to an edge of the wood.
The job is then passed through the rivet roller in mi lathe. I originally tried it at the lowest speed but found it wasn’t necessary. I now just put the lathe in neutral and turn the chuck by hand.
There’s inevitably some edge distortion and some of the impressions are not that good. Both are corrected by small hammer blows and use of mi automatic centre punch with it’s tip ground to rivet shape.
The plates are now tinned all over on the visible internal face. I use mi big iron with a wide tip. I recently ran out of my 30 year old flux and had to use one of the new environment friendly fluxes. It was horrible. Eventually found some of the old ‘nasty’ stuff.
The plates are now released from the wood with a bit of lighter fuel or petrol and wiped clean. They are now cut to approximate size and tinned on the outside edges.
Sorry all for now, seemed to have lost all the tool bar icons for posting. Back soon.
