After reading some posts here, I purchased the Snap-On R-121 reamer that was supposed to be a 2" / foot taper. I just used it for the Moog K6117 and K6136 ball joints and they are both just a little loose in the spindle, with just a slight amount of wobble. If I put on a nut and tighten it down, it tightens up---no wobble. I went back and took a K6145 ball joint and put it in a stock spindle and there's no wobble without tightening it down. So here's the question, would you guys run the reamed out spindle? Am I taking a risk? Has anyone used the Snap-on R-121 without any problems and which ball joints were used?

I'm not trying to insult your intelligence but when you reamed did you use a drillpress or a hand held drill. Reason being is I just reamed 3 set's of spindles first with a hand held drill and the last 2 with the press. The hand held I got the same wobble you did until I tightend it down. I didn't get that with the press. All you have to do is be alittle off of center to oblong the hole. If you have a press use something like a press vise to clamp down the spindle bring the reamer down into the hole so it's lined up straight tighten the spindle down and start reaming. You should be ok!

Thanks for the response. I used a hand held for the lower and a press for the upper. Both had the wobble. Were you using the Snap-On reamer or another? A maintenance guy at work yesterday measured the Snap-On reamer and came up with 1.75" per foot of taper. His co-worker came up with 1.667" per foot. (So much for repeatability!!) Anyway, I'm thinking I just wasted $50.

I believe the 2" taper per foot is ten degrees and 1.5" per foot is 7 degrees.

The Snapon 102 and 121 are for enlarging and deburring holes and don't list and degrees or inches per foot on their website.

Good luck,
