rose joint threaded inserts
Hey all,
I've just received my rose joints and the threaded inserts for making the rear trailing arms.
I know the threaded inserts you push inside the tubing, but how far?
Would you push them so the ends are flush with the tube ends or leave a few mm sticking out?
I'm just wondering if leaving a few mm sticking out and weld onto the side of the insert would produce a stronger weld than the two flush faces.

I assume you have already measured where the centre point of your old polybush was?
You want the RJ's to end up in the same place, but obviously with scope for adjustment either way.

Yer, what I mean is in my eyes a weld onto the side of the insert would be stronger than between the face of the tube and insert. Also due to the fact
I would need to grind it back to give a flat surface for the lock nut whereas if it was on the side I would be able to leave more 'meat'
on the weld.
I may be wrong, but only way of knowing is by asking!

The trick with inserts is to cut the tube at a slight angle, leaving the inset sticking out about a 1/4".
Then weld along the angle. This gives more surface area for the weld.
The angle is then placed at a 90 degree angle to the rod end when mounted.

Brilliant! Just the answer I was looking for!
So say a 10 degree angle across the tube? Or do you mean as a taper on the end of the tube?

Better still put notch it like a fish mouth.
I also drilled a couple of holes futher back and plug welded mine for good measure.
Just keep a tap handy as the heat may shrink the insert so you may need to run it through.

10-20 degree angle, weld right around, leaves about 1/8" of insert for the lock nut to rest on, that's the way McLaren Formula 5000 and
Can Am cars were done (worked on both).
