I am trying to finalise my seat mount fabrication. Due to the inconsistent curvature of the gear box tunnel I have started with welding the 3mm plates as pictured bellow. But am wondering what the best method (From the eyes of the LVVTA certifiers here) would be to finish filling the space behind the plates? Ideally I am wanting to do something to bridge the gap even though there is alot of weld top and bottom.
What are your guys thoughts?
I had what seemed like 4 options:
- "box" it up - gusset them out with 'tangs' - pack them up/through - leave as is
Hi Knuckles, 2 questions for you.
1: is this a stressed or non stressed seat? (ie: is the seatbelt retractor or mount or buckle attached to the floor or seat/seat frame) 2: have you talked with your certifier?
Some photos of the entire mount would be helpful too.
It is tough to grasp what is being proposed from the images and information provided so our preference is that the plates are formed to the shape of the transmission tunnel and fully welded around the perimeter with the bar cut to match that shape and fully welded too.
Your certifier will need to be involved if you wished to stray from this, they will need to sight the vehicle and assess the quality of the welding, bracketry and mounting systems and that they follow time-proven best practice methods, incorporating good design and construction techniques. It would pay to do this before painting or covering it up.
There is no set recipe that matches what you have done here, so unfortunately there is no easy answer.
Cheers for the replies! Will get back in touch with the certifier this week hopefully.
Heres a photo showing how I was thinking of making up shaped plates (shown as the card board cut outs) to make the mount fully welded to the gear box tunnel. Saving the issue of bending a 3mm plate with a number of different irregular bends to fit against the tunnel.
