------------------------------------------------------- > My other problem is that I have 6"w x 14" rims and > the center hold down won't thread on, Sounds to me like a problem we had with our 30-year oald Coats tire changer growing up. Center-post, with the edges of the rim actually resting on the table? With the cone hold-down that threaded onto the center post? Worked fine for years and years and years, then when everyone started getting FWD-offset rims, the cone was too high on the center post to screw onto the center post. We used vise-grips for awhile, but it didn't work well, either. I ended up getting an el-cheapo manual changer, and it's design helped me to fix the old Coats one so my uncle can still use it. Here's the el-cheapo. The part where the rim rests on is only like a 6" diameter plate, so the mounting point of the wheel sits on it. Helps when airing up a tire too, as when the beads pop in, they don't push against the table and try to launch the tire off of the machine. 
The center post has essentially a welded-in huge nut in the top. The hold-down is a 2-piece affair: The 4-legged part that sits in the rim, and the part that screws into the center post. For the part that screws in, there's essentially a threaded rod in the center of the pipe, that spins into the nut in the center post. I took an old scissor-jack, for the nut and threaded rod part, and a chunk of pipe, and made a hold-down like that for the old coats machine, and now my uncle can keep using it. Maybe you can modify your center-post with a similar thing, to get the hold-down to work right? That is, if my ASSumptions are correct about the style of changer you've got. --sarge ---** To be in compliance with the Anarchy **--- Jorden R.
