Keith,
OK thanks that explains why you trim down the height. I like switching out the stock kingpin on my Tracker RTX and MidTrack to 2 1/4" from the stock 2" one so I can use taller bushings which seem to me to give the truck a smoother full range of turn and better return to center when using high-rebound urethane like the Radikals or Stimulator bushings. Also would you personally see yourself using a 70a with your Radikal trucks? Or are you wanting them for lighter riders?
Seth,
I have heard for Indy's that some people are shaping Radikal Bushings to be just like the stock Indy bushings shape or like Bone Hardcore shape. Or you could just shape the o.d. down to fit the hanger cups, just leaving it round and not make the cone shaped bushing. Either way it is approximately 1" outside diameter (o.d.) to fit the hanger cups, but you be the judge on that.
For Tracker RTX/S, MidTrack, etc. you could do the same cone type shape or also just basic round. But again since Radikals are 1 1/8" o.d. and you should trim them down to about 1" o.d., or a tad less, to fit the hanger cups.
For Tracker the stock bushing-washers will fit a 1" o.d. round shape or a cone shape of course. But for Indy's the stock bushing-washers will fit the coned shape bushing only because the washers are too small for a full 1" o.d. round shape. You could just use flat washers instead.
To shape down the o.d. and/or make a cone shape of any bushings put the bushing on a kingpin bolt and use a nut and some washers to hold it on so it won't slip, then put this in a drill, that spins the faster the better. You could just put the spinning bushing up to either a grinder like Chicken uses to trim wheels (click here), or I put mine up to a bench-grinder which has the same type of metal grinding wheels. I like resting the bushing on the rest that my bench grinder has so it does not jump around. Or if you want you could with the bushing in a drill put it to a Belt-sander or a Dremel. Or put the bushing on a drill press and use a file (my friend Steve Collins does it this way and it is so easy too, but I don't have a drill press), or sanding block with 80 grit paper, or whatever works to take it down. I'm sure you get the idea here, but it is best to keep it spinning so that you keep it round.
