CB750 Barn find project - First Timer
Underdog1:
Well the oil tank and battery tray fit with about 1mm clearance so happy with that! Had a go making a new seatpan up today by forming the 1.2mm steel sheet with a hammer, didn't go brilliantly as I think it's a bit thick.
Will just have to make it in sections and weld together
Nurse Julie:
I will be interested to see how you get on with your seatpan as I'm just about to start making one for my CB550 custom. I haven't got a clue where to start!!
Underdog1:
Finally got the seatpan figured out. I’ve been scratching my head over how I could get the clearance for the rear mudguard/rear wheel whilst still being able to securely mound the seatpan both front and back. After a few different ideas (some of which could have worked if I was better at metal forming/ had the right tooling) I decided to create a flat seatpan with a kick up to match the rear hoop, then remove a circle of metal where the mud guard needed clearance and weld on another section of metal to form a cavity. Seems to simple!
Ready to be welded up:
All done:
Not my neatest welding but it’s all going to be hidden away anyway.
Need to make a little bracket to mount my reg rec on the battery tray and it can all go get powder coated (pending not being skint that is).
I’m going to get my seat professional upholstered, but is it worth giving the foam work a bash myself? In my head I can just layer some close cell foam on top with glue and then carve into shape.
Nurse Julie:
What metal and what thickness is the seat pan please?

Its 1.2mm mild steel. Just looks shiny as it’s been wire brushed
