Thread: Made a trammel - Family Woodworking

We had some 5/8" ply left over from putting up a shed, so the memsahib asked me to cut the largest circles I could get out of them. I figured the easiest way to do this would be with the cheap (29.95) spinsaw I bought at Canadian Tire last year, but the trammel will only do a 12" circle, and I needed 22?".

So, I got to work, went down to the local HD and bought a narrow aluminum metre stick and a couple of flat head ?-20 screws and nuts. Then I cut the ruler off at 18?" so I could cut a 36" circle (or 90cm. if necessary)

Then I drilled a couple of ?" holes to match the existing trammel, which connect to the base of the spinsaw, countersunk the holes,

and put the whole thing together, drilled a hole big enough for a #8 screw, and put it into use.

It works excellently, is much lighter than my router, and I can use it over and over again. I might look for a ?" blade, as I broke two 1/8" ones cutting out four disks.
