Building my own frame
« on: Aug 16, 2017, 11:23:39 »
I can weld, I can build a jig. I want to build a bike with a pretty wild engine, and I'm thinking I can either start with a frame from another bike, (sourced off of eBay) or I can build a frame from scratch and use a headstock from a frame I already have a title for. If I start with a frame from another bike, I'll have to do extensive modification anyhow. I will likely have to buy a tube bender either way, and make a jig either way. Although for an existing frame, the jig is likely to be simpler. Thoughts?

A pretty wild engine means powerful?

My question is how is your welding skill? And be honest because it's your life and the person you eventually sell it to's life on the line!
A pretty weld is not necessarily a good weld.

If you're confident in your welding then I say go for it.
If not, start with another frame that has the critical welds done already and modify to suit.
Or build from scratch just tacking it together, and then take it to a certified welder to be finish welded. Just make sure your joints are good hah!

Actually, not all that powerful. 50-60 hp at most. It's just very... nonstandard. Don't really want to leak it until I've at least got the basic drivetrain accomplished.

You can get jig kits off ebay for about $300, you just have to supply the box section. If you can work out a design that has the strength and shape you want then start from scratch. There will be some lathe work required, ie head stock, swing arm mounts. Modifying a frame is easier.

"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."

If you are not a member already, join up over here:

Then peruse the builds / archives. There is a stack of info on frame building (what tubing to use, which welder, how to gusset, etc).


Yes it's chopper based, but the basic construction principles apply to other frames as well.

It varies by province
In quebec, 35$ gets you a new vin on any frame that doesn't have one.

If it is to be road plated, you must then have it inspected by one of the saaq engineers.
If it passes it is considered to be the same category as if you purchased a parts frame from a dealer.
