Title: Seatbelt attach point
Post by: Brock on November 18, 2025, 05:27:46 PM
I'm trying to figure out how thick of metal I should be using for the seatbelt attach points.  I have on hand some .064" sheet 4130 but gut feeling is that I should use thicker.  This is really a question for an engineer.  Any engineers here want to pipe in?

I would make the thickness the same as the thickness of the metal attachment points on the harness. My harness has 3/32" thick attach plates.

Thank you, and I agree, it only makes sense.
That is a nice looking seat belt.  Where did you decide to attach the shoulder harness?  My thought, even though it's a bit low, is to weld a tab between two tubes at the cluster above station 4.

I welded a crossbar back there... I was able to eliminate the seatbelt brackets & the bolts, saving weight as well... My seat belt is similar to Keith's... It doesn't have the disconnect in the top, but had 2 metal brackets where his only has the one (those are what I removed & wrapped around added tube)...  Here's the one I ordered...  https://www.amazon.com/dp/B087JK6GHV

I plan on attaching my upper harness to the tube running from the wing mount tube to the top rear longeron. I wanted the mounting point to be higher than my shoulders.

Thanks guys for the pictures.  Pappy, I'm leaning towds your location.  I had already thought of doing something in that cluster to hold the harness and beef-up that cluster area.  So I finally feel I've enough oppionions to form my own, ha.  So hopefully tomorrow (Thurs) I'll finish the day with some new attach points.

Who knew a amazon had LEXL harnesses in stock.  I've been in touch with CROW and like thier offerings so now I've another to compare them with.
