    YAUPHS (Yet Another Ugly Power HackSaw)

    YAUPHS (Yet Another Ugly Power HackSaw)-20140720_110041.jpg

    The photo above is of the (somewhat) unique power hacksaw, that I built last winter. It isn't much to look at, and it certainly has some minor flaws. But overall it works quite nicely. The pulley system reduces the motor RPM, to allow approximately 70 strokes per minute. Much of the saw is built using scrap metal found at a local steel recycle yard. Other items like the pillow block bearings, were scavenged from machinery found at the same place. Only the pulleys, belts and hacksaw blades were purchased new.

    The thing that makes this design a little different from others I've researched, is the guide arm for the blade carrier or slide; which is made using two lengths, of one inch square tube placed in parallel. This provides a simple but very rigid track for the slide to move back and forth in.

    The slide itself, is composed of two pieces of 1" x 1" x 1/8" angle steel, placed back-to-back so as to form a 'T'. The blade is held by two pieces of 1/8" thick flat bar, that were sandwiched between the angle steel forming the 'T'. No need for precise pivot points, or engine rods, etc.. It cuts very accurately!

    The photo is an 'action shot', of the saw slicing through 1 1/2" x 3" x 3/16" rectangular tube.

    Nice take on a power hacksaw. This is a tool I would have immensely appreciated in a former life.

    Nice work on the hacksaw. Tools are made for functionality not for aesthetic reasons IMHO.

    There's really not much special there, as I began building the Gingery PHS. The only aspect that is 'special' if you will, is the way the arm/slide/guide is constructed. As I mentioned above, just try to envision two 1 inch square tubes in parallel, with approximately a 3/8 inch gap between them. The back-bone slide (the piece that holds the saw blade) is built from two pieces of 1/8 inch thick (1" x 1" I think) angle stock. If you look at the slide cross section, they've been welded together, back to back to form the letter 'T'; but with sections of 1/8 inch flat bar 'sandwiched' between the angle. Overall, the slide forms a big letter 'F'... I'll try to post a couple of extra photos of that part of the machine. Everything else is pretty much unremarkable...

    If I had to build this thing over from scratch, I wouldn't start with the Gingery motor, arm mount, as it's simply too flimsy... Every time the crank pulls the slide back, the back end of the saw 'wracks' or twists slightly... Someday I'll rebuild it and beef it up. It doesn't seem to affect the cutting accuracy though...
