Yea, I own them. I have never saved the knockout. I keep the 2 saws at
The Blade install is opposite for the two saws, backwards if you will.
Please refer to the owners manual, page 8, for the Bosch.
And to Page 8 of the PC saw manual
Now - Notice a typical Circ saw blade....
(I have never bought this particular blade, just a decent picture)
The teeth point to the left at the top of the blade. The arrows on the blade
indicate a counter clockwise rotation. Put that on the PC saw label out.
You put that on the Bosch, assuming it had a knockout, label IN. In other
This is typical for blade left designs, I think. I know this is how it is

I have never changed a blade on any worm saw but my own.

Okay, backwards, opposite, inside out... btw, if one doesn't save the
diamond shaped knockout(s) they can be purchased so the blades can
interchange between saws.
Okay, I've got a burning question:
For those that use and love their skil 77 worm drive
How often do you change the gear oil?
I bought a garage sale skil 77 for $25 and got it running
for another $25 plus a decent blade. The guy at the repair
shop where I bought the parts said not to worry about the oil.
For what it's worth, I've got that old skil and one of the
fancy lightweight Bosch worm drives. They are both made in
the same factory now (in the USA). They both work great.
They are heavy, but I am young.
One added benefit of the worm drive saws is that you can buy
a special metal cutting blade and use them to cut through a
steel I-beam. The blades are rather expensive though.
Sidewinders spin too fast and don't have the grunt to do this.
