This is my band saw spiral cutting jig which is the first application of the rubber and wood gears I posted a while ago .
The jig is a prototype to prove out the principle of this mechanism and so far it has produced several pieces which quickly where put to use ( see pic 6 )
The jig consists of a rack which is fastened to the edge of the jig and a gear which simply gets fastened to the work piece and as the work piece is rotated it decreases the radius at a constant rate .
The radius can be varied by using different gear sizes .
The gear is held onto the rack by the opposing edge of the rack and the edge is replaceable to accommodate different gear sizes ( pic 2 ) shows the spacer and and gears .
I will build a more substantial jig based on what I have learned from this and post it when done .
There is a video that my wife made and I will add it when I figure out how to post it .
The application for this are interesting and will open a new avenue for me .

Thanks Joey
When I was having my coffee break I thought of you and a box design based on this would be cool I think .

That’s exactly what I was thinking of. The only problem is I don’t have a bandsaw yet. Once I do add one to my shop, I will be building one of these. Unless you start producing them and then I will just order one from you. LOL

Used band saws are cheap to get ,all I use is a 9” Ryobi cost me $50.00 .
Used timing belts you can get from a repair shop for a thank you ,they just throw the away.

That’s a idea. I don’t have a lot of space so the size machine I can get is limited. I was thinking that I wanted to be able to resaw lumber at first, but I do it on my table saw now, and while the band saw will have less waste, is it really enough to justify a expensive machine. I just don’t know. That’s the main reason I have put it off.

I see what you have made with this and sorta understand the concept with using the gears but I think the boy in the pics probably knows more about woodworking than I do. LOL
Great job/photos/and jig.

Hi Jim
This was a easy jig for me .
Just went to the shop and started building and experimenting ,the hardest part was the location of the jig relative to the blade .

Your prototype looks pretty darn good already. Simple yet ingenious ! (it’s always simple once someone else has figured it out huh !) Thanks for sharing !
