modifying blades for Skil 67 and 127

[hertfordnc]

I have a collection of battered user grade vintage skilsaw worm drives.

This includes the 67 which takes 5 1/2" blades and the 127 which takes 11 5/8 blades. A 12" blade will work in the 127 but NOBODY makes a blade bigger than 10" with the Diamond Arbor and nobody makes a 5.5" blade with a diamond arbor.

Back when i first got these saws in 2016 i scoured this site and all the other places where they talk about old tools and there did not seem to be any viable answers.

I took a stab at modifying a cheap 5.5" blade with a demel. It was usable with a slight wobble and at that point i gave up.

Now i have better tools and a better space and i'm ready to try this again.

I have a plunge router attachment for the Dremel, i'm thinking that might allow me to trace the diamond with a bit more accuracy.

But i can't be the first person to experiment with this so if anyone has any input i would be grateful.

Machine shop? Won’t be cheap.

I have three 67's, no 107 or 127 (yet) but one or two older saws that take a 3/4" bore or 1" bore blade. I haven't yet found a solution but my bet possible resource was the tool shop that used to sharpen my blades. I only recently remembered they have a fully automated CNC blade sharpener that does perfect work and they don't charge too much. I'm now sitting on a few blades that need to be sharpened and I need to call around to see who can do what for what $$. I'll be sure to ask about bore modification as I can see a little bit of a market for that service. I'm also going to look and see who near me has an abrasive waterjet as that would be better for the plate than introducing heat with a laser or wire EDM.

Sounds like a perfect job for a die filer.

I've made a few blades for my Skil 67 and Skil 127 using a dremel with a carbide burr and a cut off disc with great success.

I have a jig with a diamond knockout filler, a bolt to fit the diamond knockout and a 1" washer that fits tight on the bolt. I use the jig as a template and use a steel scibe to scribe the paint and then use the cutoff disc to cut out the rough diamond and then use burr to clean it up until the diamond knockout filler fits cleanly but tightly into the blade.

It takes me about 30 minutes a blade so I make two at a time to have a backup blade available just in case I damage a blade on a project.

Doing it this way, I've yet to have any problem with blade wobble.

It takes some time and test fitting but works great. Just take it slow and only remove a little material at a time.

Just my two cents.
