where can I buy the necessary parts to do rose joint rear arm


it's easy to find the male rose joint

but hard to find the "piece" you weld and with will be abble to lower or upper the male rose joint


sorry, don't know the technical word for this part

 

I made my own, the first cut was with welded nut into threaded rod. It cost a bit to get the collars sleeved to be exactly right...
They are plenty strong enough, no movement, I have tested the welds and belted them.
I am now getting some machined up to that size just to be sure...
Which I think is the most common practice.

I am very happy at the moment because I just got an engineer to review my work and he said the welds were all good to go...

Here is a pic I sent to Lincoln....
