CB750 Barn find project - First Timer
Underdog1:
Bit bored of looking at engine internals and as my bike frame is back i decided to make a start on the seat pan with my new angle grinder.
First i cut a template out of card
Then traced it onto some 1.5mm steel sheet
And then cut it out. To be fair it was easier than i expected even doing the curve, needs a little tidying up but considering this is the first time I've ever used an angle grinder I'm happy. Just started shaping the rear kick up a little, the metal is easy enough to bend with your bare hands.
Like trigger has shown in one of his previous posts i need to make a bracket spanning the frame tubes at the rear to bolt the rear of the seat to and the front.. not sure ye ill have to figure it out. Im thinking about cutting a flap at the front of the seat pan that will bend up and over the rear tank mounting bracket so the seat will sit flush with the tank (thats what that extra tab at the front of the seat pan is for, wanted to make sure i had enough material). Alternatively I could try and shape the metal like this:
Although i not sure i have the skills!
I was hoping to use the same sheet of metal to make the brackets that i need but if i am able to bend it by hand then I'm worried it will bend too easily which will be annoying after I've had it welded and powder coated. What mm thickness would you guys recommend?
Underdog1:
Little more work on the seat pan today
Might have to change the front a bit as i want a relatively low profile seat and thats as low as i can make it to cover the bracket, not entirely sure how people get around this as some seats look pretty slim
mike the bike:
How do people manage to ride with those skinny seats, do they put a wodge of foam down their trousers?

Got some loctite SF 7200 gasket remover stuff to help me avoid damaging gasket surfaces with a razor blade

Anyone used this before? Apparently it eats paintwork and as I'm not repainting now it's made m a little more reluctant to use it. I suppose I could spray it on and then immediately wipe down painted areas with thinners or maybe spray it onto a rag and rub it on to the gasket surfaces?
Trigger:
Try using carb cleaner to soften the gasket, I buy a ton of this from a guy on the market at a pound a tin. You will still need a blade to take the gasket off but, it will be soft.
