choppin n weld'n another 'junk yard' frame

Getting mm done. I'm gonna put a 1 1/2" band around the edge of the plate. I've learned to check and tac weld..check again from all angles...another tac..then weld.I had to cut tac's loose..knock it straight, tac again..ready now.

Well, by golly the seat is coming along just fine. Lot of cut'n, file'n and weld'n..smooth it it in with some bondo..I'm hoping spray contact cement will hold my nugahide seat cover. The right pic is where the idea came from.

Shock part is for the seat to absorb the bumps?

Just noticed second pic for hinge. Nice job!

Tony01 · Feb 10, 2017

Nice. I like your rear dropout mod.

Thx MT, prolly didn't have to use a 1/2" bolt, but no wiggle. This build is using the swapped crank engine.

scratchbuilder · Feb 10, 2017

Hey 01, the drops surprised me by coming out the same! They are on the inside to give extra clearance. Gonna be single speed coaster brake.

Looks great Scratch!

Be sure to use the lowest lbs# on the shock. If too high will be a rough ride!
Air shock would be cool!

scratchbuilder · Feb 10, 2017

That CB is why I try to make all the swap meets, to find another air shock. The last one I picked up for 15$.. It is almost worth it to just spend the 100$ for a new one, cause the ride is worth it. They are bit*hen.

A$$ on air, the best ride!

Like the title says, choppin n weldin...I won't have any chain rubbin issues..the three cross rods are to keep alignment ahead of me, you get behind, and ya get the "oh dang it".

Went for a ride to Adams Motorsport Park, the track was holding a SuperMoto race. Absolutely a thrill hearing those thumppers roar buy! And the mini moto's..one kid was 9 and FAST. Rode road racer style. Be going more often now that I know its not just go karts,,and they don't race the shifters there anymore.

I got the rag joint sprocket on, and you know takes a little fudg'in to get it centered..now all I have to do is disassemble, and turn the sprocket around...

cannonball2 · Feb 16, 2017

Yeah, I hate it when I do that.

Might have to make a toolbox/battery box behind seatpost. A lot of space there. Like I could make something like that..prolly be flat shaped piece of alum...lol. One of the 'things' I was after was,getting the engine lower and I did. Seeing that I'm going to spring saddle this bike, I'm thinking ,cut out the seat tube, bend one for a better look.

The drop out to slot out mod, I can't see where weld is done, but it is welded or brazed too?

The bolt there also hold it together?

scratchbuilder · Feb 17, 2017

MT, the drops are just tack'd. The bolts will be removed, they allowed for adjusting till tack'd.

Knowing I'm a budget builder, I was going to use a cranbrook wheel...was..rim and spokes for me are ok..but the hub..is way to cheaply done. Could use advice on a coaster hub*

scratchbuilder · Feb 21, 2017

Laced up a schwinn coaster hub. Got the sprocket on the right way. I'd like to space it out by putting another three brackets between the sprocket and rubber. By widening the chain stay, I can now mount the Js low. The seat is done. That lil shock is awlright. It doesn't bottom out. Have to go to a auto upholster to get some foam. What I have is way to soft.

msrfan · Feb 21, 2017

I get foam from the dumpster behind a carpet store. Carpet pad is re-bond and can be spray glued in layers to get the desired thickness.

scratchbuilder · Feb 21, 2017

Yeah msrfan, thx..that it can spray glued is a plus!

MEASURE TWICE · Feb 22, 2017

With that wide seat probably the foam you can get to repurpose would be good. I had tried some foam I had around for a banana seat that needed more padding for trail riding. It just was too soft and bottomed out too easy. I bought a large rectangle piece on line for about $15 I think. Still bottoming out. I cut a partial section out of this foam and put more resilient foam in as a subset per say. I find it worked out well, just the covering is old tape and lots of it. I'm think eventually maybe some cover over that to tack it better to the existing banana seat.

I actually need to stand on pegs more often than not on trails and am now fitting Honda trail bike foot pegs I got from Ebay. The pegs I had that were the mini bike type my feet slip off too easily when in steams or mud crossings.

What kind of material are you planning on using to cover the foam, and how to attach. Pictures if you can... thanks!

I'll be watching. Always like to see unique builds.
