My husband was nice enough to write up his instructions for making a round knitting loom.
Here they are.
Steps to make a round loom
1) Choose a square piece of solid hardwood like oak or maple ¾” thick. Find the center of the square and mark it.
2) Use the following formula to determine the circumference of the circle you need. The example in the formula is for a 48 pin, ¼” center to center round loom.
Take the number of pins(48) and multiply by the
spacing you want .25(1/4")
this will give you the circumference of the circle
which would be 12" next divide the circumference(12") by 3 and this will
give you the diameter of the circle you need which would be 4". Then just mark out the 2 axis lines
and continue to go around in 1/4" increments.
This worked out for me and I wound up with 48 c pins
1/4" center to center.
This formula should work for any amount of pins you need.
4) Now that you have your circle drawn and the pin locations marked, I drill a 3/32” hole for each pin(when using 1/8” cotter pins). Drill hole 3/8” deep for each pin. I used a drill press but a hand drill will work as well and cut cotter pins to the correct height you want.
5) Next draw a circle 3/8” smaller diameter from the center point this will be the center hole.
6) Draw a circle a 3/8” or larger diameter from the center point, this will give you the outer edge of your loom.
7) Cut the outer circle using a jig saw, cut the inner circle by drilling a hole in the center then cutting with a jig saw.
8) To install pins I put a flat head bolt in my drill press, held the pin in place and pushed it down with the drill press 3/8” down into the piece of wood. (note: drill press was not turned on)
9) Sand inner and outer edges, top and bottom till smooth, coat with paste wax(available at hardware stores) or polyurethane. I used the wax, it dries faster and you can use your loom right away!
10) Congratulations! Your all done!
