I was inspired by Armand’s jig, very nice design. https://www.lumberjocks.com/projects/416943
I decided to try to make one. Without plans I had to do some guessing but without Arman’s post and video there wouldn’t even be a place to start. So, thank you to Armand.
The Dremel tool holder was fairly easy, the length of the tool made for a good start for dimensions. I had a lot of trouble with the copper wire indexer and the spring. I had a length of 1/8” brass rod so I changed the shape of the indexer into a simple “U” which was easy to bend. The indexer holder is mounted on a small slotted platform for adjustments. I threaded both ends of the brass rod and added a nut to each end. One nut keeps the brass rod from sliding out and the second nut adds weight to the indexer so that it drops down to it’s starting position when the jig is retracted. This eliminated the need for a spring. Also I didn’t find a need for a stop as the jig can’t travel any further when the indexer pushes the blade to it’s top position.
It’s not as elegant as Armand’s jig but it does the job. I may refine it more at some point.

That works really slick! I like your indexer.

On a blade with teeth that coarse I find it faster to do it by hand. Have you thought out an adaptation for finer tooth blades?

Here is a video from Mathias Wandel on his version, with a fine tooth blade not on the saw. https://www.youtube.com/watch?v=LxvYXbeaLxE

Super cool idea how it advances the blade.

Nice jig, but you’re only doing the tops. What about the bottoms?

I followed the lead of jigs made by others. I don’t have an answer to your question.

That’s OK, Does it cut any better after sharpening that way?

I usually do the bottoms and not the tops.

It always cuts better.

It cuts better but not as well as a new blade. How do you sharpen the bottoms?

With a 4mm round 600 grit diamond file by hand.
It takes about an hour for a 72” blade.
Cuts like a new blade.

I’ve been looking for a Dremel bit of the same size but haven’t found one yet.

A lot of the bits for the Dremel are very coarse and will take off too much material.
