Default Spindle Welding

Ok so I need some advice, the spindles on my kart need to be cut off and replaced with longer ones. What’s the cheapest/safest/best approach to doing it including tools needed?

Thanks

Post a picture or two, all depends on the application. May be a possibility to make entirely new ones if you are decent with a welder, I've built my own and saved the $20 and they hold up just fine.

Couple grade 5 fine thread bolts, a way to ensure they're welded at the right angle, relative to both the steering arm and camber (if your kart has any camber, that is). That's about it. Weld, then let it air cool. Do not quench till it's below 500°.

I say grade 5 because the higher alloy of grade 8 is more prone to cracking at the weld if not done properly.

Here’s a few pictures. Clearly the rim is too long for the spindle. I noticed bmi has a spindle kit with a 6” bolt. I guess something like that would work for the front but what options are there for the dead axle in the back?

Found these on the BMI site. Will something like this work to just replace the entire thing?
