I have been looking at some parts that need to be fixed to the firewall, and I found them just ... not good enough. So I made my own coil, a reservoir for the Lockheed braking system and the accelerator lever lever mounting.
No problem for the coil and the oil reservoir (basicaly a small jar with lid), these are easy to make on a lathe. Also their supports which were much too thick, and have been replaced with a small aluminium strip. The bolts and nuts of 1mm were added, so the supports can actually be bolted to the firewall. It adds realism, and at the same time you are able to mount and dismantle as much as you like.
The accelerator lever mounting was a bit more fiddly. Because the shape of the parts is not too difficult, I decided to shape it from copper sheet, instead of etching them. The main part is cut in 0,4mm copper sheet, the smaller one which is to hold the return springs in 0,24mm. Between them I added a small part out of a box with watchmakers leftovers to simulate a hinge.
You then solder everything together, and done!
Again everything is bolted to the firewall, and we're ready to tackle some more parts.
Have fun building.
