I had a lull in projects earlier in the week so I made a compass for use in the barn on layout of pieces for the lathe. I made this one out of mesquite because it is very strong and stable. it is 12” long from the pivot to the point and will draw a circle from 1” diameter to 30 3/4” diameter. This time I made one where the pencil goes up inside the arm instead of on the outside. It will take up to a 4” long pencil and I have a lot of short pencils to keep it supplied for a long time.

All the wood parts are mesquite and finished with Danish oil and then buffed and waxed. All the brass parts are tuned from solid stock. The steel tip is hardened tool steel.

Cheers, Jim

Pretty Pair Jim!
I’m sure they’ll see plenty of use!

Nice, Jim! A lot sharper looking than my dinged-up stainless steel one, for sure.

That’s something I could use Jim, I hadn’t thought of making one. Great idea!

Thank you all for the nice comments. This compass really works good. I used it yesterday on a chunk of walnut.

Hi Klaus. I don’t have any build photos except the one where I gathered all the parts together before oiling it. I don’t have any drawing either. I made the drawing on the wood before I rough cut it and the rest was design as you go. I can tell you that I made it out of 3/4”x 1 1/2” x 14 blanks. Then I laid out the rough shape on the wood and bandsawed them to a rough shape and turned the round sections on the lathe. I turned down the ends for about 1/2” for the brass to bottom out on. I got all the brass out of my storage bin. I buy some on Ebay and from a local recycler and I always buy a little extra,,hence the bin for it.
Here are some shots of my bin that I never posted and a relative size shot if you want to scale it and build one.

Cheers, Jim

Nice compass Jim. The brass and wood combo has an amazing look. Wow 30 3/4’’ that’s a big circle.

Fine work Jim, 100% home made is great!

I often grab my old drafting class compass and after seemingly forever to spin the wheel getting it to the right size, I find it’s 1/4” too small for my needs (it’s a 6”) Maybe I’ll break one of them down and use the parts for something like your beauty (at 12” 8^)

Thanks Dave, Bruce and Brian.

Hi Bruce, My old drafting compass has just a piece of lead at the end…and I know what you mean about turning the wheel on that fine thread forever!

Cheers, Jim

Thanks, Lew. I’ll made an envelope for it in my lathe cabinet. Otherwise it will be all dinged up after a while.

Cheers, Jim
