Back to work on the TriBSA.....
Last time I was in the garage I glassed in some pieces of aluminium strip with rivnuts attached to give something to attach the seat pan to the seat unit.

I then cut some holes that line up with the rivnuts in the 15mm thick foam that had come with the seat unit. I sprayed this foam and the seat pan with spray adhesive.

I then waited for the vapour to evaporate and stuck them together.

Next I added three layers of cheap camping mat foam using the spray adhesive. I had hoped that the foam would compress over the areas where the strips with rivnuts were but there were distinct raised areas above them. To get over this problem I used an electric carving knife followed by 80 grit paper on a sanding block. While I was at it I flattened the front of the seat and shaped the back of the seat. I finally glued a piece of camping mat foam on the top and sides of the seat. I'm quite glad with how things turned out...

Now I need to figure out how to cover it.
While I was in the garage I decided to sort out the mounting for the LED rear light I bought a while back. When I was glassing in the rivnuts to the seat pan I had also glassed in a piece of slotted angle to the seat unit. A bit of work with the Dremmel allowed me to mount the light on this bracket.

The LED light needed quite a bit of modification to fit but nothing that a Dremmel and hot glue gun couldn't cope with.
The next thing I did was weld the anti roll bracket (bought from Nick at K&S) onto the frame

Here's a picture of things as they stand at the moment.

lookin great Chas, keep the progress pics coming 8-)
