The arm is actually a sports cub (they are wider than the standard cub arm), even though the bike is a bantam!
I will measure it up for you
With the bushes its very strong, I made them a press fit in the tube. Plus don’t forget that most of the load is transmitted though the shocks to the sub-frame, the swing-arm is more for control (like a radius-arm / wishbone on a car)

Yes, you may be right 6061 is better
But the alloy I had was slightly to small in diameter, so I’m going to make some patterns and cast a set in LM25

Its mig welded, I cleaned the weld to make it look neat
I made some bushes to go in the tube to add strength

Progress of swing-arm One side finished, other sidw still needs filing down
I think I’ll have a go at making some alloy Cub Hubs next
(Can’t make up my mind if I’m going to turn them from billets or cast them, If I cast I will make a few sets )

It’s now done, (cut and extended the tubes)
I’ve extended it so the wheel has some clearance from the front of the swing-arm

Can anyone help me, I was thinking about extending them 3/4" ???
-
Just about to lengthen the swing-arm on my bantam project, anyone know how much I should lengthen it by?
It’s a wider type sports cub swing-arm

Does anyone know what grade aluminium is used for replica cub hubs?
I’ve got a bit of 6082 and was thinking of make a pair

Ive done more observing than riding, its easy to knock the observers but there seems to be very few riders who are willing to give it a go!
It would be nice if people put by there comments how many times they have observed?

I Use Dexron II (works well) fill to half way up the sight window in the clutch cover

Mines the same, but you get the knack after a while
Try using your hand when stationary

Is the OKO just a copy of the Keihin PWK ?

I purchased as set NJB shocks, they seem very good and they were set-up to my weight

I had the same problem, I put some rubber car hose on the kickstart shaft
