Welded lower steering shaft/column
Anyone passed IVA with the lower part of steering column extension with welded Ford triangle bits to heavy duty pipe.
I bought a part finished Locost/Haynes roadster and the previous guy welded the ends on. Remember reading that if you weld the ends on they should be
pinned as well. Don't really want to buy expensive parts from CBS or the likes.
Thanks in advance for any advice/knowledge shared.

do you ever see this in OEM parts... Pinning will just add a stress area a crack could form.

I welded mine with no pins, passed IVA and two years on there are no issues. No idea why someone would want to pin a properly welded joint.

As others have said, I wouldn’t pin.
Ideal would be to sleeve the shaft to connect the odd pieces so you can be sure of a strong joint.

Thanks for replies. I was maybe wrong about reading about pinning the shaft. The guy that built the chassis was a welder offshore and has MPI certs
for the chassis so it gives me some faith that the welding on the extension he fabricated is good and strong. Just about finished the upper bearing
modification, so I will refit the home built extension, but put more of an angle than was before.
Might get round to posting pics soon so I can get some feedback/pointers.
Cheers

Mine passed with like you describe, I welded it and was confident of good penetration. Didn't come up at IVA but I remember a few years ago
people talking about pinning it as well. Mine was ll nicely painted and looked professional so I don't think they questioned it.

I knew I had read somewhere about people using roll pins on steering extension. It was on this site few months back. Link above.

I cut both my sides with a slot. In the slot went some mild strip. The two tubes were cut at a 30 degree angle to maximise weld area. I then put a
sleeve 4 times faster than the cut. The sleeve was also cut at an angle to maximise weld area.
If it breaks then a tank has driven over the front of the car and I've got bigger problems.
