fredfret Posted June 24, 2019 Report Share Posted June 24, 2019 Yes it works. I don't feel I gain enough to make it worth the effort. Blades cost from 20 to 40 cents each and last quite a while. Just my opinion.Β OCtoolguy and Foxfold 2 Quote Link to comment Share on other sites More sharing options...
John B Posted June 24, 2019 Report Share Posted June 24, 2019 It definitely works. Brenda. I have made one for both my saws. I don't use them very often. When I'm cutting portraits etc once the blade becomes blunt, it has also weakened so you won't gain much with thin blades. However when I'm cutting 25mm of thicker solid timber with #5 + blades it almost doubles the life of them.

loftyhermes Posted June 24, 2019 Report Share Posted June 24, 2019 For what the blades cost I'd sooner put a new blade in. Foxfold and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted June 24, 2019 Report Share Posted June 24, 2019 You will also lose the lower teeth that might be reverse teeth so that is something to think about. That's a major complaint about the Jet saw. Β Β Quote Link to comment Share on other sites More sharing options...
Scrappile Posted June 24, 2019 Report Share Posted June 24, 2019 (edited) I've heard of it, never tried it.Β Maybe a good idea if you are doing something with non-reverse blades...Β It always makes me feel bad when a blade gets dull, I take it out and see the shinny part,,,, shows how little of a blade is actually used....Β Not that blades are really expensive, but I hate waste.Β Same reason I like to recycle,,, not because I think I will save the earth, but because I hate waste.

WayneMahler Posted June 24, 2019 Report Share Posted June 24, 2019 Seen this before. IΒ would be concerned about blade breakage on the area that was cut with. Depending on the wood and the depth cutting creates heat which also contributes to blade dulling . For the minimum blades cost I wouldn't think is be feasible if that blade broke and caused an issue with the project your working on.

Paul, let's design a cheap spot welder that we can weld the blades end to end and get more use out of them. It shouldn't cost us more than a few thousand dollars. LOL.

dgman Posted June 25, 2019 Report Share Posted June 25, 2019 (edited) Using Flying Dutchman Ultra Reverse blades on my DeWALT, Β I canΒ achieve the same thing. Since the reverse teeth on the FD UR blades are every third tooth, I can adjust the blade to sit high in the blade clamps. Then when dull, I can move the blade lower into the clamps. Works fo me. This also works with skip tooth and all other blades except regular reverse tooth blades.

teachnlearn Posted June 25, 2019 Report Share Posted June 25, 2019 (edited) There is a small spot welder used to weld strips to watch batteries and battery cells to make battery packs. RJF https://www.amazon.com/battery-Welding-Machine-Charging-Function/dp/B01MF8LKYK/ref=sr_1_7?keywords=battery+welder&qid=1561497438&s=hi&sr=1-7 Some hobby techs. use these to make solar panels. They buy solar cells and weld a group, then another, then another, then weld the groups together to make a panel, then make a panel and mount the cells, then weld some more to create connects to connect to the next panel.

ike Posted June 27, 2019 Report Share Posted June 27, 2019 @ 30 cents per blade it's not worth it to me.I useally get one hour of cutting time on a blade with very little burrs on the back. the time gained by this is eaten up with sanding.

Harry Barton Posted June 28, 2019 Report Share Posted June 28, 2019 In my limited experience, this is one of the first things I tried when a blade got dull, as it just seemed an obvious thing to do.Β I didn't make anything: just laid two pieces of 15mm chipboard on the table, laid a piece of thin ply on top and cut a slot in it, which raised the work up by about 20mm, into fresh teeth.
