« Part 2: Dorn's patent Revolving Mitre Box part one Part 3 of Vintage hand tools in my shop series Part 4: A video starring Dorn's patent revolving mitre box »

The basic parts of this box are a lower or base carousel, the upper turntable, two movable fences and the upright assembly.

A view from the bottom shows the base piece

This is the upper section with the fences. The fences more independently of each other. The two thin thumb screws secure the upright assembly on the four locator pins. The other thumbscrew locks the base to the upper section. Marketing literature touted the rotating box allowed two workers to use it at one bench!

Finally the top saw guide assembly.

Inside the upright there are brass saw guides that move up and down in grooves along with two saw stops to keep the saw from bottoming out.

Back

Front

The first test cut came out totally square.

The box can handle at least 7” of width but this number decreases depending on thickness because of the design of the uprights.

As you can see in the photo the upright casting limits thickness. Up too about 4 1/2” wide the stock can be just under 5” thick.

Anything wider than 4 1/2” is limited to about 3” thickness.

The rotating section is pre marked at 90, 45, and 22 1/2 degrees and indents help locate the moveable fences.

Even though the box is heavy it has a tendency to slide on my bench. I’ll make wooden base with recess to fit the feet. I’m still tinkering with this thing for the time with the hope of making a video shortly so stay tuned.

Thanks Duck. I’m trying to do a video but the shop looks like a garage sale warehouse right now. Gotta tidy it up for visitors! :-)

Guess i’m insecure! Hold me :-)

Trust me, there will still be the debris and detritus of woodworking and tool hoarding. Good thing I’m not a collector.

I was beginning to wonder if anyone was watching this.

The video will take a few days to make and edit; i’ve only done one other. Ran into a problem that’ll take a little time to resolve but i’ll fix it at a later date. Tell ya about it on the video. See you then.

It looks like a cool tool, Kevin. Sorry I didn’t comment earlier. Was busy trying to get my new shop organized unpacked and ever so slightly organized today.

Moved to Santa Fe back last September, Kevin. Started the process of building a new shop around Thanksgiving, and started moving into it this week. Almost all of my tools have been sitting in boxes in the garage for the past six months. Luckily it’s dry enough here that I didn’t have to worry much about rust.
