Got some more pics for those interested.

Got the suicide shifter started, this will be a small one behind my leg.

Me dreaming of the finished product (should be 2-3 weeks before all the fabrication is done). Notice the engine stitting beside the bike now, and frame is now prepped to get some welding done.

SC, did you use a mig or an arc welder for the frame? I'm thinking mig with some inner tube reinforcements.

Cool, I've been welding this small stuff and it seems to bond ok, but I was a bit worried about it breaking. But if inserts will make it strong, I'll use that method. I'm 1000x better with the mig anyways haha. I guess the biggest thing to remember if your not sure about the weld, cut it and do it again right.


Another pic; The welding jig we're almost finished.

Exactly, but I wouldn't recommend too many attempts at the same weld due to the annealing process caused by the heating/cooling/heating/cooling! Having said all this.. I was always much better with an Oxy/Acetylene Gas torch than electric welding any day!!! That's how I was taught at College!

Thanks man! GMC is a good place to post side projects. The community is great, and lots of people here are really knowledgeable with just about any type of hobby. Perhaps we should as for a section of the forum to post our other stuff. This would make it easier to get to know everyone on a more personal level I think.

Yes sir, once I get an arc going I'm ok. It's getting it started thats a real B. It always wants to pull the rod right to the tubing. But if I turn it up too high, she melts through haha. I've never done gas welding before, but our little lincoln mig can be converted. Maybe I'll have to try that too, I want to get all my bases covered so I know which method is best.

You won't convert a mig welder to Oxy/acetylene!! wink.gif I'm talking 'Old Skool' Gas welding with flames and everything!! laugh.gif biggrin.gif

If you use Gas on your MIG set-up you'll find that it's a little easier (the weld should 'take' better), and make sure you get the Wire Feed and Amperage set right!! Just practice on your old seat rails until you get it right!

And in some time, this is going to be the line of the bike. Still have some bending and straightening to do tomorrow, but hopefully we'll get this frame nice and true by tomorrow night.

THE BIKE IS FINALLY RUNNING!!!!!! AND IT SOUNDS MEAN!

I took a vid with my cell, so I'll see if I can get it on youtube tonight biggrin.gif




This vid turned out pretty bad. Too bad you can't really make out the audio because I was running the bike without headers -> too loud for cell phone haha.

Thanks dude. Tank, seat, and bars should all be here by end of next week. Which works out great because I have a math final to study for this week.

I've hit a snag in the bobber build.

Turns out my back wheel have a vertical offset of of about 2-4 degrees. I did everything right....except check the stock frame LOL.

Oh well, a cut and another afternoon to make some proper spot tacks and we'll be back on track!

My seat and tank have arrived, on a positive note.
Attached Image

This is NOT my bike, but just to give an idea what tank and seat I went with. This is a pic of the guys bike that I bought the tank and seat off of. Not bad for $270 cdn/pair.

I also cut out all the BS from the triple tree support, and welded in a nice plate across the two bars that run down, and then a vertical one from that plate to the backbone. And it looks really sweet!

That's it for this week....it's been a slow process with all my homework this week (math final on monday).

Don't forget that the front cradle will move slightly when you release some of the stress when cutting the back end out of it!! wink.gif

Yep, it sure did haha. I noticed that the other day too.

I have a plan for straightening everything though.


1) The cut the rear corner of the frame so the top and bottom are apart.
2a) Then make a relief cut on the top rear wheel/seat supports to bend them back straight at the proper angle from the forks.
2b) I'm going to cut/insert/re-weld the backbone and line the seat plane perpendicular to the forks (to ensure the seat pan is horizontally level with the forks).
3) Move the bottom frame rails parallel under them.
4) Use a apparatus I made (welded onto the bike lol) with a level, and one I made to bolt onto the rear sprocket to make sure everything is true again.
5) Burn that sucker home!
6) Test ride with my friend pushing me

7) Get drunk in either joy, or sorrow tongue.gif Ah...lucky #7
