u cut the shaft with a grinder and shave down the nuckle as well then grind about 1/8 off the cut end of shaft to press them together then weld. i didnt get the chance to get the collars today so ill finish the thread tommorow but heres the start of it

basically after the first pic u get a collar that evens out the shaft to the nuckle . weld it then get another collar and slide over both of them and weld. i went to tractor supple for collars. they are like $2 each. i have a couple shafts cheap. the nuckle u can get off ebay they didnt change all the way back to 90s with the cr 250 kickers and u can use the shafts as well there cheap on ebay

with final sleeve before welding. if u want perfect welds on outside have a good tig guy do it like 2 minutes of welding

weld the outsides and your done. this is the same way they make em at walsh and houser. i just didnt use a lathe or a tig.

nice post.
-Please share the length of the collar.
-And inner diameter of the collar.
That way there is no guessing.

-Also what year shafts do you have?
-I am interested in a shaft please shot me a price and include shipping.

I need to make one.

thanks

We need an extentor so my son can try to start this quad. I can do it but he has a hard time and I have seen a few guys that welded something on the kick starter to make it come out farther from motor. kind of like you made here.
