Skilsaw Model 77 Super Duty 7-1/4' Circular Saw - vintage worm type 13. Since there's no bolt holding this stack of 9 pieces together, it's been a nightmare trying to get it all in place so far. Skil 5380-01 Skilsaw Corded 7-1/4' 12 Amp Circular Saw Tested Working Great £7.02.

SKIL SKILSAW 7.25 INCH (7-1/4') Circular Saw Model SPT67WE NEW No Box. In 1924, The Mitchell Electric Handsaw Company created the very first Portable Circular Saw, powered with a unique gearing system utilizing a worm drive. That makes no sense: someone has to assemble this in the factory, and it needs to be easy for them in production.Īny suggestions? And, if anyone has one of these, could you double check the order of parts above? The dang manual doesn't show a decent picture of this assembly. You people rock, and if I haven't forgotten I'll post shots of the finished bed frame.They called this new portable wonder, the Skilsaw. Scariest thing I ever did with a circular saw was stand on the top rung of a ladder and cut notches into roofing plywood - and that was a direct drive, and I definitely self-medicated with a bit of Tito's that night, well after I was finished. Note to the respondent who noted the dangers of worm drive - thank you! I already knew, and have a healthy terror of kickback. I'm leaving a photo here of how it looks, and will check back in a bit - let me know if what I did is in some way dangerous or unsafe. Now I tried holding the blade with a pair of slip-joint pliers and couldn't get the bolt to budge. I got a hefty washer on there, threaded the bolt back on, tightened the you-know-what out of it, and the difference is obvious without even running it - before, I could hold the blade with my fingers and spin the shaft with a wrench.

So it's a problem with the blade thickness. I got the bolt off (yes, reverse thread) and yes, the diamond knockout is knocked out. Any help would be appreciated!Įdit: Thank you all for your suggestions! This scares me, but I really want to be able to fix ths so I can get back to cutting.

No jerk or bounce-back, the shaft spins but the blade is obviously not tight to the shaft. If there's no real drag it cuts fine, but the least thing makes the blade just stop. We replaced the blade for something newer, as I've got some cabinetry to tackle - but neither he nor I can get the blade to tighten down. It's an old solid metal case, the thing weighs like three times the Ryobi direct drive, but when it's running, it doesn't feel like anything at all! I love the darned thing. I was having so much trouble controlling a direct drive circular saw due to the gyroscopic twist when starting it up, my 'adopted brother' found me this wonderful worm drive Skilsaw. I'm on a farm, and I'm a little person learning to do big work.
