This is my first home build machine…

Last week Thursday I started to build one using a motor that’s been moved from one pile to the next for a couple years, but by midnight Saturday I realized it was hopeless and pulled the drum, and one pulley, The drum has been modified quite a bit but is pretty much what I started with ( I’ll add pic of what’s left of the beginnings later)...

I built it from what I had laying around, wood, hardware for drill mount, extra belt and two of the bearings (there are 4)...

All I know is internally the drum is 5” across the flats x 13 1/2” long hexagon, the pulleys are 1 to 2 step down 2.25in to 4.5in, the rpm no load max is 300 but don’t know why I would what it that high, for the most part I’ve run it up to about 100rpm…

The drill does fine and doesn’t get hot, the system has 8hrs total run time in two secessions…

Overall its 21in long and 10.5in wide, no idea how tall…

In fact I’ve had the drill for over 10-12 yrs but never used it except to see it worked when I bought it…

It in fact works quite well I finished up and did some tweaking the past two three days and used it for the first time yesterday…

When what I’m doing is finished (auger bits), I’ll refer to this in another thread.

Added a couple more pics to the original post, as usual the camera wouldn’t take one so I guess I’ll add it later…

I realized since I have little in the way of specs pictures would help…

I remember the bearings are 1/2” id x 1 1/4” od, and the end boards are 6” x 9” with the bearing holes 4 1/2” up from the bottom edge…

The trigger rod is 1/2in oak dowel with a double layer .005” steel shim siliconed on to help prevent excessive wear.

Ok then. You got my curiosity up. I’ll be watchin to see what your polishing in it, and to see how well it works.

The first pic is after they were all in evaporust and clock cleaning solution 6 hr each…

The other pic is after doing a few secessions in the drum polisher, they are all smooth to the touch…

The top bit I did by hand a month or so ago for comparison the adjustable auger I never touched…...

The HF media I used I feel is OK for removing rust which is its stated use on its label, and I feel it does a fine job at that…

I haven’t chose anything to use further at this point…

I’m trying to keep telling myself they are not new and never will be.

I could use something like this for the rust on a few things that I have.

How to you think the threaded rod and the wood will hold up over the long run?
