A few weeks ago I found this 82 model 500 in incredibly good condition and priced very reasonably.

I thought about chopping the tubes to make a mini of it. But the original tubes are really in great condition and I wanted the option of going back to standard size. So I took the original Way Tubes from my 510, Cut them to 26 3/8 and 25 5/8. I put them on a lathe and cleaned them as well as I could. There is some pitting remaining but they are smooth enough that the headstock will move freely. This is what it looks like when reassembled as a shorty.

And here it is in relation to my stock size 510.

I'm still playing with it to learn what modifications I might make to increase functionality. But I've already used it in the table saw mode, the drill press mode, and as a lathe. And it should be perfectly functional as is to drive my bandsaw. So far I'm very pleased.
