Yeah. Actually hooked it up to a steam engine. Seemed to work fine, but couldn't really find a way to control the downward advance. In soft wood it wanted to just drop and in steel it didn't really seem to want to head down.
 
My Grand Father that was the Blacksmith had one kind of like that. The majority of the machines in his shop had been setup to be run off a line shaft. So his power hack saw was run off the drill press drive with a flat belt. They cut slow but worked well.
 
Not like that, but I built a reciprocating saw a few decades ago. Was working at a machine shop while in college and scrounged some scrap steel, some bearings, etc. to make it. Currently have a large commercial recip saw in the shop.
 
The original setup was driven by a hit and miss motor that set out the back of the shop in a small building. Then when they got enough electric power the line shaft was powered by a five HP 220 volt motor. The hole is still in the block wall where the line shaft went out. The shop was built in 1925
 
We had a couple in the shop where I worked. One was a Marvel. It had some kind of a clutch that would disengage when the cut was completed. They cut as the blade moved back to the fixed jaw of the material holder and raised slightly for the return stroke. Was replaced by a bandsaw.
 
They were used in some in tool shops I was in but never put a piece of steel in one to cut it off.
 
You mean that MATCO creeper that's in the background? I had one exactly like that issued to me when I bought my MATCO tool set back in 1980 when enrolling for auto mechanics. I don't miss it.

Were you powering it in the correct direction??? The crank and connecting rod, affect how the blade draws during the cut stroke and glides back without pressure on the teeth.

Yes, had one at a boat shop I worked at in the 70s.

It was one of the few tools that somehow survived a fire back in the 50s.

It had been electrified.
 
That's a very good question. I also notice that this one seemed to have a lever with a spring on, maybe something to do with the down pressure?
 
Years ago we had a similar one at work. It had an electric motor on it. We aquired it after it had been sitting for many years. Even came with some new blades. When we first tried it, put a piece of steel in it, plugged it in and turned it on. It raised way up in the air and slammed down exploding the blade. It happened extremely fast! We replaced the blade, manually turned it over and it seemed to be fine. When we turned it on the 2nd time, it did exactly the same thing, scared the crap out of us. We finally determined that the slides were just very dry. It had the old type oil cups on it, remove the cap and fill with oil. Once we did that, it actually worked fine. Used it for many years before replacing it with a band saw.
 
Got one just like it out in the shop to,even painted green, must be more of them still around than I thought.Originally they were set up for a line shaft setup. Good old tool that still cuts accurate and great.
 
Hi, my old friend now gone had one. When it finished its cut, the blade dropped down a bit and switched the power off. Ed Will Oliver BC

Dad and I used a similar one (different brand) for years and I still do on occasion. Ours is driven my an electric motor. You DO need to drive it in the correct direction for it to perform as designed. (It does make a HUGE DIFFERENCE.) It needs to be operated "slow enough" to work properly. The blade needs to be installed to cut on the PULL STROKE. (Even has instructions - name - cast into the frame.) Everything needs to be oiled and greased properly to get good smooth operation. It probably has (or should have) a "cut off switch" or de-clutching feature that needs to be properly "set up"/adjusted so that it "stops" when the cut is completed. We always had best results with "high speed steel blades" with coarse teeth for best chip clearance. "Cutting oil" is best used for some types of steel. It is really great for cuts in thick heavy steel. It cuts accurately, clean and straight. Easy "fit up" and welding. Very handy and helpful. You look like you have a "GOOD ONE".
