Some progress on the trike, small steps. I made a stencil of the area on the bike that we're using to attach the rear sub-frame too. Transferred that shape to 3mm MSteel and cut out the LHS plate, some rough shaping and a 16mm hole. Fits ok, but still needs some more shaping and mounting holes drilled. The stencil transfers to the RHS with a little bit of allowance to be made for jiggly poke poke fitting.
From these two plates will be welded the connection points for the new swing arm pivot point.

This is what I'm aiming to replicate:

CAD. My preferred method as well..
Cardboard Assisted Design
Stencil board......living up to its name! I was introduced to it 20 plus years ago and I still use it to make one off parts. Quicker then designing it on the PC and leaves plenty of room for fudging..LOL
