Title: Lucas Mill blades
Post by: BuckShott on November 07, 2019, 03:17:14 PM
Has anyone on here built their own jig for silver soldering teeth on a circular sawmill blade?
I have an older Lucas 8-20 and am looking at doing my own blade repairs since my closest "saw doctor" can't seem to get it right   arg-smileywhen I have taken my blades to him for repair. Any insights would be much appreciated!  :)

Bummer! That doesn't speak well.
I looked at the jig Lucas sells for doing it at one point but never got any further, my doc does a good job and tensions the plate cheaper than I have an interest in learning.

Their jig is a bit too pricey, I think it would be fun (and more affordable) to build my own, but need to research and get good information first.
What does "tensioning" mean?

Tensioning starts with flattening any high or hot spots then moving the metal in the saw plate to put the rim in a slight amount of tension so that it runs true. Not as big a deal with a small diameter blade as a large headsaw but it is still done right on down to tablesaw blades.

Here's a good article;

Thanks for the link Don, that was very interesting. I suppose even if I am able to learn how to properly attach tips, my blades would need to be "retensioned" occasionally. 
If the guy (blade shop) was closer, I would work with him (be more patient) with the results, but he's a couple hours away and I have to drop off the blades and pick them up a couple weeks later (usually a couple months by the time I am able to get back down there).
I am kind of the "independent type" so figuring out how to do it myself will be rewarding.

I would like to know what you come up with, always been tempted to try. I'll try to get some pics and tips next time I'm down there. The shop I use is a bit over an hour away, in fact I keep forgetting to call to let him know those were my planer knives my wife left at the door of the shop a couple of weeks ago.
