Hello.

My name is Jocke and i'm from Sweden.
I am building a chopper with a Bsa 650 twin this winter. I have made some progress and tought I would share it with you.

I built a jigg and made a lot of measurments.
The frame is 8" up and 2" in from a 1948 Harley frame. Rake is 50 degrees.
It will be long and skinny.










Alot of grinding here to make it fit tight.




Testfit with the engine and trans






Engine mounts

Then fully weld the frame









The engine and trans is alot shorter then a Harley big twin drivetrain. To fill the space between the rear wheel and seat post i will have a standing oil tank.
Made one from 2 fire extinguishers.




Found this Apollo Competition tank in bad contition at a friends house. I thought that it might work..

Thank you for the kind words! It makes me really happy.

Goldy, if you mean ground clearence, It will be probably like 4-5" depending on the tyre:



I made a support bracket for the lower motor mount:





Tack weld:



Then weld the junk together:



Some random frame images:











I tried to make some what of hidden tank mounts. It might work.. Not really finished though:









Thats all for now. Stay tuned

Your welds are stellar. Im inspired to just burn a lot of electricity trying to get welds that are close to that good

What sort of machinery bent this heavy bracket up?
I have this crap in the big hydraulic press. It works surprisingly well..
I have pretty basic tools to work with. Alot of angle grinding and patience.



The rear wheel is laced up. Bsa hub with an old harley rim. The rim had a bit of rust so it had to be painted.



I am planning to go with a black rim in the rear and chrome in the front. Someting like this



I got the rear tire. e240 shinko. I think it will be perfect for this.

You sure have. My hundred-thousand-pound press is a lot newer and better than that one!

Please keep up the swell work and picture show.

Had an old fender that i will try to use. It needs a lot of work and also change the radius. I dont have a shrinker or english wheel, so it will be some kind of angle grinding involved!

Do you happen to know what bike that fender used to be attached to? It looks British (but then everything looks British to me). I'm just wondering if, somewhere out there, some restorer is crying bitter tears for want of that very fender, and saving up to spend all his money on one just like yours but not in as good a condition.
