hi zakboy, you still building one a week?.. got my last big event next w,end then will be bang at it like you. need to lengthen the wheelbase really so the passenger isn't the first point of impact in a shunt.. [would look odd with a big overhang past the axel to have bumper protection] unless i make it a single seat job. want two really.. still gonna be perhaps 9ft overall. the axle is on stands about where it wants to be and looks OK. just want to get the joints strong enough..

I'm certainly no expert weldist, but I was always told to ensure parts to be joined were as close to the same thickness as possible. I always use tubular slugs.

hi dobber, i think you will have room there to perhaps weld in some gussets where you join the added frame work too for extra strength, and weld in a couple of tie bars from underneath the passenger seat rails down to the added frame work

did have a couple of gusset sort of things on before i cut axle off [ page 8 of this thread] don't want to put anything from rear seat as i went for the floating look if poss zakboy. when you join with a slug where do you actually weld. could maybe find a tight fitting tube to do it all but its seamed so makes it hard

As MM mentioned you want to use tube slugs as near to the inside diameter as the tube you are putting it into. then the tube you put over the top wants to be the same as the exsisting frame diameter the outer tube then wants sloting along the length then seam weld into the slots

You also want to be rosette welding the slug mate. Drill a 10mm hole through the tubes, then another one at 90deg to the first, you can also offset the distance of the holes from the end of the tube, insert your slug, weld the holes up, grind flat. Slide your drilled tube on the other end of the slug and weld the holes up, then weld the join. dont grind the joint weld though. As you stated earlier, you will get better penetration when welding 2 pieces of metal the same thickness. You will have (presumably) half an inch metal thickness on the joins, more than enough strength.

these are the four bits to join to for the axle mount and carry on to some sort of bumper set up
looking at your photo, why dont you cut off the inner tubes and weld the new bit directly to the cross tube? it would eliminate 2 of your joints.... just a thought.

good idea Pete, Christ, sometimes you need to step back a bit to have a rethink,surprised i didnt see that... could redesign a bit that way too.. that's a definite... knew there was a reason i checked in now n again.. think i may cut them off then run new ones at an angle to meet the outside ones, therefore just one long clamp on each side of axle instead of two smaller ones.even put shaped flat plate between them welded to the cross member for strength

Nice to know you've taken us along for the journey Andy. Any chance of a sandwich from the buffet car?
