Recently a friend who is a retired railroad machinist for the C&0 gave me a electric motor driven reciprocating hack he built 30 some years ago. I replaced the wiring to include a new cut off limit switch. The old G.E.. motor tests out good. Cuts good and is a really nice addition to my small shop. Do any of you folks have plans for this sort on machine? I believe he said it was in Popular Machanics magazine. It would be handy to have the original plans, just for history sake.

Hi for some reason these have become less popular than they deserve,possibly since the availability of cheaper type bandsaws horizontal or otherwise. I like the action on these and they cut well I wonder why more people don't do up the older ones which seem to go cheap on ebay Alistair

It is nice to be able to set up the saw and continue working as the saw drives on. The limit switch takes care of the saw when the work is done. It does not cut fast and that is good. I timed it through a 1" squard bar of 1018; took about 3 minutes with the original blade. I am thinking about an oiler to keep the work lubed.

Thanks for the link rockrat!

In high school we had a big old power hacksaw that I was fascinated by. I think I'll add the PM DIY version to my list of stuff to get to.

Russ,

Would you mind posting some pictures of it? I would enjoy seeing what he did!

Thanks...

Alistair. Your nostalgic comment has inspired me. I acquired a little reciprocal saw in the mid 50's, all cast iron, gibs on the slider, blade lift on return stroke, cast sliding weight, buttress thread on the vice screw, auto shut-off, oil cups, belt drive, and after market flood coolant. I have no idea of the mfg. Perhaps it is a 14", and ~70 lb. without motor??? Haven't used it in 35 years or more. I may now return it to its original glory, it deserves some TLC. Thanx. Lloyd

This is the saw i do most of my cutting with not as fast as the band saw type but it works pretty well, it has auto shut off when the cut is done . That is convenient when you are cutting something like 2" sold stock those can take a while. The blade is 10 inches, it is very light weight and when i am done pick it up and put it on the shelf, this little saw has cut lot of metal , max cut is 6 inch pipe

Samuel, sorry for the delay, I'll need assistance to get the saw out where it can be photographed, I'm still in this wheelchair. I erred re the vice screw, it is a quick locate with a 'saw tooth' rack cast in the bed. Pics next week will show all the features, thanx for the interest.

Greetings Mike Bur****; As soon as I lay my hands on a digital camera, I will post pictures. I am not technologically advanced as I should be. It needs a bronze spacer on the drive wheel for alignment, other than that, it made a 3" cut through .500 aluminum plate the other night with no problems. 3" is the limit of its range.

Take care, Russ

P.S. My daughter is married to a Bur****, from northern Va.
