Swing Arm: extension

[machinebike]

Did Anyone try extending their swing arm using the front forks?

Um I'm new here but not that new.:smile:

Umm do you mean like use modified front forks as a swing arm for the rear ?

 

[minidragbike]

I think he means like the way the do with dragbikes?
Extend the wheelbase

But by saying the front forks makes me think he wants more rake, like a chopper?

 

[TeamCheap]

You may be right but choppers are all over the place and for him to ask if anyone has done it is .......well........ut:

Hopefully he'll come back and elaborate a bit on it maybe with a drawing even.

Hi, sorry not enough detail
My rear wheel hits the frame so I need about 3 or 4 inches for clearance.

I cut pieces off front shocks to add to back with little pieces of tube to join the extension pieces.

I placed ends of fork pieces in vise, compressed to use for rear wheel axle and bolts.

I've built stretched swingarms for our mid bikes and I'm currently building a stretched out Wards mb....

drill a hole in each piece and then plug weld the sleeves to the swingarm and the extension besides butt welding the two halves together...

Can' t use the weld idea, I was going to run bolts through each side.

No access to a welder?? I wouldn't trust bolts, thats just gonna be a weak spot where you drill the holes plus a flex point...

any chance your near Toledo, Oh?? if so I can weld it up for ya...

Thanks for the offer, but Im in bel air, md

What would something like that cost to have welded?

if I did it "FREE"..... if you take it to a welding shop probably $75 minimum

 

[rocketman]

take it to a muffler shop if nothing else probably about 15 bucks.:weld::weld::weld::weld::weld::weld:

I am trying to understand what you are meaning:doah:.

If I drill a (small?) hole in swing arm part, then one hole (top and bottom)? on extension, would I drill the holes all the way through the connector piece or just through the first layer of metal then drop a weld in the hole to grab the connector?

If the seem is welded, should I leave a slight gap so the weld fills in the gap then I can file down so it is smooth like one piece?

a plug weld looks like this pic. drill 2-4 holes in the swingarm and extension pieces. DONT drill the connector piece. Slide the connector 1/2 its length into swingarm, fill holes w/ weld to bond swingarm to connector. then slide on extensions. Fill holes w/ weld. Make sure its all lined up first. Now they are all joined together. you can now weld around the seam.
Get it?:smile: In the pic...............
the part here on the left is swingarm. the part here on right is connector
