I would love to give credit where credit is due but for the life of me I can’t remember where I saw this idea. I want to say it was Wood Mag but I can’t be for sure. I saw something like this before and thought what a great idea but what if I want different sizes? So I came up with this. I line up the cutting tip of the saw blade to the edge of the wood and drew a line and drilled a 3/16 hole every 1/2”. So now I can cut a perfect circle from 1” to 18”. In the picture I made a 5” but it was to big so I cut it down to a 4” just by moving the pin from 5” to 4”. Its just that easy. I tried to cut one free hand but I really didn’t like how it turned out. Thats when I made this.

Nice jig!

How do you attach it to the band saw table and do you align the center line with the leading edge or trailing edge of the blade?

Sorry Lew I guess I left out a few things. I’ll put up more pics tomorrow. But I took some scrap 1/2” ply that I had that fit my miter grove perfect. Predrilled some holes for the screws so it didn’t expand any and attached it to the bottom of the jig to keep it stright. Then with the bandsaw off I align the jig to the leading edge of the blade to the line and put stopping clamp where I want it to stop then pull it away, put my piece to cut on and push it to the stopping clamp then turn the piece clockwise and there I have a perfect circle.

I need to make one of these for my band saw. That is a great idea. I would think that you could make one that would accomodate larger holes even up to about 4 ft in diameter, but you might need have some sort of support for the end off of the saw table.

I like this jig I have just made one for myself. Can I suggest with the addition of another pin and as long as the holes have been drilled square to the table rebate you could use the jig for cross cutting stock square.

Chairman, Thats a great idea. Do you have any pictures? There are actually a lot of different things that could be done with this basic plan. Maybe counter sinking 2 sets of tracks and putting the kreg bench Klamps to hold down your work to get a nice even cut if you wanted to do some angle cuts.

Jeremy, thanks for your reply and New Year greeting from the UK. I have an old hand saw jig from the 60’s that uses dowels in differant possitions in order to cut angles, thats where I got the idea to add another dowel to do cross cuts. I added a toggle clamp as a hold-down, and a good tip is instead of adjusting the rubber pad every time you cut a differant thinkness of stock I use a wedge of wood to make up the differance in thicknesses.

Have your say...
