spindle brackets.

[project]

Hi all.
I am building the arachnid buggy from spidercarts as a school project. the design calls for 20 spindle bracket weldments, if I had to buy them the cost will total 70$.... so i decided i was going to make them my self.
Is it a good idea if i use a U-channel and cut them to the required width? do the have to be perfectly square (90 degrees)? and last question will they be strong enough using 1/4" thick U-channel?

I found a sit where he makes them from scratch using 3 welding pieces of metal.. but i think with that method it's almost impossible to be square.. here is the link to the site http://www.diygokarts.com/kart-plans/steering-plan-spindles.html. thanks for the help in advance =]

Yeah don't get those spindle brackets, the holes aren't very accurate either. I also wouldn't suggest channel, it usually has tapered legs. The best thing would be to just make tabs with holes to weld onto the frame, just flat bar like this;

Also, be careful with the arachnid plans, many people building them have run into some big issues with the plans, which as far as I know have not been resolved. Search the forum for build threads of the arachnid, you should find some useful info.

thanks r97!
by any chance do you own any spindle brackets? it would be of great help if I have the exact dimensions..

I do, I do not know the measurements, but they aren't really needed for the suspension arm pivots. You can just make the suspension arms & bushings (or use ball joints) then measure them so you can make the tabs. Kind of hard to explain, but it should make sense once you have the arms fabricated.
