« Part 8: Planning the Construction of 12 Chairs Part 9 of Greene & Greene Gamble House Side Chair series no next part

With my pattern sanding technique proven and a length of UHMW-PE tubing delivered I got to work making a bushing for the spindle sander. I roughed out a 1” piece of tubing to start.

There is just enough clearance between the sanding drum and the table insert to fit a bushing. I turned the bushing on the lathe to a nice press into the existing table insert.

The bushing provide a 1/4” offset from the sanding drum which will make design of the patterns easier.

A nice property of UHMW-PE is that it is extremely low friction. This will allow the patterns to glide smoothly along the bushing and also facilitate insertion and removal of the bushing from the table plate.

The spindle sander project kept me busy while I was waiting on delivery of a new bandsaw. My trusty 12” Craftsman served me well over the years, but it was time to upgrade to something with more capacity for this project. Every part on these chairs is touched by the bandsaw except the two front legs and the small lower connecting stretcher. Some of the parts, like the center back slat, are 5 inches thick. A Bigger saw was definitely needed.

I researched a few options on bandsaws. I was looking for something larger than a 14” saw, but not so big that it would be difficult to get into my basement workshop or take up too much room. The Powermatic PM1500 was on my very short list, especially after working on one while at the Marc Adams school a few weeks ago. As luck would have it, SCM put the Minimax saws on sale right around the time that I called to get pricing, putting the MM16 in the same price range as the PM. With larger capacities nearly everywhere, including a 4.8 hp motor, the choice was pretty easy.

About a week after placing my order I received a call from the freight hauler that my crate was ready to pick up. The crate nearly filled my 8 foot utility trailer and had a shipping weight of nearly 800 lbs! I was starting to get worried about getting this thing into my shop.

Luckily, the shipping crate was very substantial and accounted for about 200 lbs. of the weight. Even so, moving this saw was not going to be a 2 man job. With the help of my neighbors backhoe and some clever rigging we were able to lower it down my outside stairs into the shop.

Next steps: clean and tune up the MM16, finish designing and order my routing templates in AutoCAD to be CNC cut and pick up another load of Sapele.

Wow that’s an upgrade!!!! said the jealous LJ reader ;+)

I just upgraded my 15 year old 12” Delta bandsaw. I bought a new blade, special order to get the 82” size it needs.

That is a really slick idea with the UHMW tubing (pun intended). I wasn’t aware that you could get UHMW in tubes. I’m definitely filing that clever spindle sander insert idea away for future reference.

Love your process! Can’t wait to see you start making sawdust. You’re going to have to paint your new bandsaw to match your Powermatic showroom.

I’m excited to see your CAD/CNC templates!

McMaster Carr carries all sorts of great stuff and they ship really fast as well. Top notch outfit. If you need machine knobs for jigs, odd size screws, etc. they will likely have it.

Once again I am reminded that there are so many companies out there that sell just about everything. I use McMaster-Carr to order things at work but I hadn’t ever thought about looking there for woodworking supplies.
