I am currently working on a project that will require me to swing an arc with an 18 in. radius. I have trammel points with a scribe on either end but won’t hold a pencil or marker and I also have a couple of smaller compasses. So this is what I was able to come up with. Everything was made from scraps and or recycled stuff. I can now swing an arc with a 24 in radius. I love making tools! made with oak dowels, and oak scraps from an old dresser.

Very nice. I made a compass once…out of a clothes pin and some tape and a screw…not nearly as big or nice looking as yours, but it was all I had to work with where I was at the time and I wanted to draw some arcs.

Very nice.
It’s funny… every time I think of a tool that I need, someone posts one that they made.
This place is filled with great ideas.
Thanks for sharing.

Thanks for the nice comments guys!
I made this to be able to layout a pattern (using radial line development) on cardboard for a shop built cyclone I am planning to make soon.
One other thing I want to do to the compass is move the pencil thumbscrew up a bit and counter bore the hole to accept a sharpie pen.
Dennis, the locking mechanism is simply a lid stay I scrounged a while back from an old record player TV console someone had thrown away. I had to remove the part that attaches to the lid and place a screw there instead.
I keep a hammer, Flathead and phillips screwdrivers, pry-bar in the car at all times so that whenever I see some one throwing away old furniture (or even new junky furniture I can salvage the hardware off it. I have hinges, screws. and all sorts of hardware in coffee cans in my shed just waiting for an opportunity to be re-used or re-purposed. In most cases the hardware is the most usable part of the furniture, if the wood is solid and not particle board I will take that apart too. Sometimes even MDF furniture if it hasn’t seen any weather will make it’s way to my shop. I don’t have a big shed so I have to cull the junk in it from time to time and this spring I really have to get it organized.

Thank´s Tinnocker
for reminding me of this with the recycling thing ….. LOL
I always seems to forget it when I drive around and see a cointainer people is filling
when they empty a house ….not that I don´t pick up things but this with
only hunting the hardware as you have done I always forget outside my own premisis
take care
Dennis

I have a pair of old lid supports so I may make a couple of dividers like this myself. Just a note, your link is a dead one. (http://www.twhgrafx.com/blog/).
