Where did you get those pivots for the A-arms to attach to the spindle?!
The A-arms I got with the ball joints welded / riveted in place. I made a small bracket that I'm going to weld the spindle to, then use lock nuts to attach it to the A-arm ball joints.
Yes I know some of my welds are fat and dirty, but remember this is my first welding project!
I believe the pivots are tapered. They're made for a thick spindle, which is required since no kingpin is used. I know this because I have the spindle I'll upload a pic to show you, this weekend.
The matching spindle is also tapered, 14mm top, 12mm bottom of each hole. I think these joints take a heavy load. Just curious how your design turns out.
Flux core welds. One thing I always do is immediately take a wire wheel in my drill and get that white junk off the welds. So you can see better and especially before listening to us critics here. Give us and yourself a good look at the weld not the flux dust. Also if you need to touch up a bad weld you don't want to weld over that crap.
Here's the spindle pictures I promised. I got them second-hand of a quad, roughly 50 US $ for spindles, hubs and drum brakes with all the nuts and washers included.
Yes, the thread part of the joint is not tapered, only the smooth part is.
