Power Hack Saw

[Travis7s]

Picked this thing up on Kijiji today, mostly just because they are cool. LKS "Kwik Kut", manufactured in Manitoba, missing the legs though.

The while I was there the guy made me an offer I couldn't refuse on a pretty new 13" drill press. Its the big brother of my bench drill press which was the first power tool I ever bought 13 years ago.

Then he gave me this little Craftsman scroll saw for free, don't know much about it other than it is cute and loud as heck. Sorry for bad photos, I think frigid garage and lights not quite warmed up will do that.

Good catch!

I like the old power hacksaw, even though may not be as technologically advanced as a bandsaw.
Just cool to watch it do its thing.

That old jig saw might turn out well... when you get time post some pics of it torn down.

You made out great. I like that power hacksaw.

Cool saws!
Is the Power Hacksaw good to go?
Or will she take some rebuild. Likely huge fun regardless.
The scroll saw is interesting. Is there alot of flex in the arm?
Curious about what could be done with old leaf springs.
Hmmmmmm.

Tomorrow I'll crank up the heat and go play with them.

The hack saw seems good to go mechanically, but I have no blade to cut with yet.

I think the scroll saw dates back to the 50's. I'll get some more pictures when I take it apart.

I got the model number off the scroll saw, there is some info out there on google and vintage machinery. Dates back to the 1940s, Sears actually called it a "Magnetic Jigsaw". Theres no mechanical linkage, or even a motor for that matter. Inside is a big electromagnet, and a thin spring plate mounted above it that the blade attaches to. When you flick the switch the magnet sucks the plate down (with the blade) and then lets it spring back up, and it just oscillates like this really fast to make the cutting motion.

Cleaned up the hacksaw a bit, a lot of the stuff I thought was rust was just grime, so its pretty nice and blue all over. If the motor is original, it would date the saw to pre 1957 as that is when the Leland electric motor company closed. Here is a video of it running as-is, I gotta get some blades!

Tubalcain has a great video on magnets, and I know from experience they can really mess up an arc when welding. I'm certainly no electrician, but isn't this the basic concept of how motors work? Is there enough power to make decent cuts?

This one is like a big pull type solenoid I guess. I cut a piece of 1/16" fiberglass with it, and it cut pretty well actually. Its super loud even with hearing protection so I didn't try too much. Apparently you can tune them to reduce the noise but that will be for another day...
