Like I promissed yesterday i was looking for the jigs and finally found the jigs I used for the coppering of the HMS Triton.
First trials were with this roller I made with an older (i Think Proxxon) saw blade of a circular saw.
....much more teeth, than the usual rollers, usable for smaller scales
another jig I made, but were not happy with the result is this one
So finally I went to Bernhard Froelich´s way he showed in his book
first of all you need a stamp rectangular shape and install small nails in the pattern you need, cutted heads and flatten the cut as much as possible, so that the nails are not making holes in the copper. These are the "fathers" of the jig
On the top is the jig used with the Triton of this building log, on the left side every time as an example the copper plate as a result. On this Triton the copper tin was a little bit too thick, in the meantime I am using thinner copper with better results, one example I will show you later
Now we come to the "mother". You have to produce a block with a notch in the size of your standard copper plates, in this notch a stiff and hard rubber block has to be installed and fixed.
from the copper sheets you have to cut with a sharp knife or tin scissor the copper plates
Put one copper plate into the jig, means on top of the rubber, into the mother
on top the father with the nails in direction of the copper
put this into your plain vice.....the pressure you have to check and make some trails......with mor preassure the nail pattern is getting more intensive
and the result, put the nailed copper plate out of the jig
I made this photos fastly yesterday evening in order to show the principle.....hope this is helping
