I've never hardtailed a bike. But now it's my next step.
I've ordered 1 1/4 x .120 DOM tubing to finish out the frame.
Im shaft drive and keeping the sway bar.

This is what Im trying to connect.

And this is what ive come up with.

My question is if i split the tube and weld the metal plate inside will it be strong enough?

if its welded properly it will be. need to weld all sides and cap the open ends.

Am i making this to complicated. Its hard to find pictures where you can see how its been done. It looks like some people of just welding a flange off the bottom and some are collapsing the pipe at the end and drilling a hole through it. Im open to suggestions.

Hotel i may have some pics thatl help pm me ya cell and ill try and send them to you. The ones Ive seen done the guy had two eyes machined like the shock mounts that he welded to the hardtail so the swingarm could still move freely once un bolted. The way youve pictured it will work but as JRyan said youll need good welds and to cap the ends.

All the clean/stylish shaft drive choppers ive seen (online) have used the drive plate, like this clean example i found during a quick google search

If you dont go this route, you might as well just make a solid strut to replace the suspention.

you could always internally sleeve it....something to this affect.....

but with it tapering at the end like this fence post pc (i am not condoning using fence post pcs) lol. Id suggest some solid bar, inserting it and plug welding it.

I like to run the axle through the frame and then bolt the front of the drive housing to a plate welded to the frame.
