    Although there is no arm lift on the return stroke blade life is not a problem. There is no more wear than if the blade were in a hand saw. I think the direction of the crank lifts the blade slghtly on the return.

  • @myfordboy
    @myfordboy  11 років тому +3

    Blade life is excellent. To use the whole blade would mean a longer stroke which would result in a much larger machine. This is a compact bench top saw.

    What a neat little mechanical saw, I’ll have to keep a lookout for one of those for our workshop.

  • @randr10

    My father had a commercially made version of one of these. It looked ancient. The bow that held the blade was made of a casting that looked like a gigantic c-clamp. One feature it had that you may want to add to this one is a kill switch that would engage when the blade falls below the cutting plane. The reciprocating action would engage a lever at that point and it would switch the machine off. My favorite feature of that machine. As a cutoff tool, it was superior to the other ones we used (horizontal band saw, chop saw). He actually sold the band saw when he saw how well this worked. Never regretted it.

    • @myfordboy
      @myfordboy  11 років тому

      This saw already has an auto cut off but thank you for the suggestion. The switch is located on top of the body and the saw frame activates it.

  • @myfordboy

    Despite what you belive I can confirm that ony one blade was used in this video. The same blade went on to cut many more bits of steel later. I am using Bi-metal HSS blades with no lubricant. Cutting fluid actualy reduces the saw's perfomance as the blade seems to slide over the work instead of cutting.

    • @lucrebrazzi4069
      @lucrebrazzi4069 2 роки тому

      You are correct. I hand saw stuff like that big pieces and larger and it can take six or seven hours,even with a larger hunk of band saw blade in a meat cutters "hacksaw" I make a kerf on each side to reasonable stay in the middle though but my cuts still wander and the finish is too rough because the cuts don't meet exactly. People don't understand that if you DONT BREAK A TOOTH,and keep a fair amount of teeth in the cut,those blades can cut an amazing amount of material.

  • @ArnoldsDesign
    @ArnoldsDesign 12 років тому

    I agree. Though it has a short stroke, making it look fast, the cutting speed is low, and combined with bimetal, works well. On the cutting fluid, I found the same to be true with my horizontal bandsaw. Water soluble oil coolant inhibits the blade from cutting well and it clogs up my vise screw with sticky sludge and chips. I use it with no coolant, and have no issues with the blade heating up. Cutting oil with a quart of tap magic added might work awesome though, as it does in drilling.

  • @ArnoldsDesign
    @ArnoldsDesign 12 років тому

    Nice powered hacksaw. I can't imagine doing metal work without one of these or a horizontal bandsaw.

  • @TheMotorgoat1
    @TheMotorgoat1 10 років тому +1

    That's awesome. I love making my own power tools and I like how your hacksaw turned out. Nice work and I hope that you have great luck with it.

  • @CosmasBauer
    @CosmasBauer 11 років тому

    This is such a nice machine! I now got a cold cutting chop saw which is much faster but not nearly as nice and enjoyable to watch as this saw but loud and a little intimidating :)

  • @brandoc1950
    @brandoc1950 13 років тому

    Great saw! I built something similar about 20 years ago, but sold it when I bought a bandsaw. I've always wished I'd kept it. Mine was smaller and unlikely to have been as as accurate as yours. I'll have to do some digging and see if i still have the plans.

  • @Noeman2009
    @Noeman2009 9 років тому

    Awesome machinery..Great solution, very economical. First: Hacksaw blade is cheaper than band saw blade. Second: Hacksaw blade is widely available. Third: Power consumption is lower than cut-off saw. It really helps if electricity in the household is limited to power 2HP motor maximum....Now I really want it :(

  • @jjsbt
    @jjsbt 13 років тому

    I ordered and recieved the plans from David. Although I have not yet built it, the plans appear to be just like his videos - very well done. There are lots of explanations, pictures and links to videos that point out specifics. If you like his videos, you will like these plans.

  • @myfordboy

    Mine has an adjustable stroke. Sometimes it needs reducing to suit larger material.

  • @ricbarker4829

    It's a nice build and well thought out, but the cheap Chinese bandsaws have a big capacity and are hard to beat. If you are hard up for space though and have the bits lying around, this would be a good project.

  • @deaftodd

  • @kentowakai1234
    @kentowakai1234 8 років тому

    I think I could use a regular light switch. The arm would drop on the OFF side when it is through the material. I'll use tubing and bearings because I don't have that bar stock, and my coin jar for the weight.

  • @myfordboy
    @myfordboy  13 років тому

    @HomeDistiller I haven't found it necessary to provide blade relife on the backstroke. It works fine without it. A Good quality blade lasts ages.

  • @Garretthierisser

  • @Traderjoe
    @Traderjoe 10 років тому

    I used to use a similar design machine, but would always have oil flowing into the cut. Did you not add the oil for clarity sake for the video?

    • @myfordboy
      @myfordboy  10 років тому

      I find on steel the saw cuts better without oil. I do use oil on aluminium as it prevents clogging the teeth.

  • @astriknon

    Hi... very nice cuts you are making there. How fast is the crank rpm??? That looks too much speed but i see it works great. I'have seen many older ones but they are really really really slow movement.

    • @myfordboy
      @myfordboy  10 років тому +1

      It is faster than the regular ones, about 230 rpm. Sounds fast, but as you say, works a treat.

  • @manudehanoi
    @manudehanoi 12 років тому

    perhaps because of the rotation direction, the return stroke pulls the saw a bit up. Maybe this could be increased by attaching the arm on the saw frame
    a bit lower to that the return stroke pulls upwards and the cutting stroke pushes down

  • @hololightful
    @hololightful 12 років тому

    That is really brilliant. I was thinking about finding an old one and restoring it cuz I have a metal shop in my garage I got every piece of metal working machinery you can think of. And I really need something like this that's small. And then I thought hell I got Motors controllers gear reducers flywheels pulleys and what I don't have I can make. I should just build one!
    Question you just have the one gear reduction?

  • @Rustaholic777

    Yours works faster and back in the day they did not have such good blades.

  • @Rustaholic777
    @Rustaholic777 12 років тому

    Sure I could build one of those but then what would my metal cutting band saw do?
    Besides the band saw is always cutting instead of spending half of it's time going backwards,,,,,,, A very nice heavy duty one on it's own table was forty bucks at a swap meet.
    It needed a $4.95 bearing replaced that took less than 15 minutes to do.
    In that time I also re-greased it's gear box.

      @myfordboy  8 років тому +2

      it's the same blade throughout and it went on to cut more afterward. Blade wear is not an issue.
      The large metal took a couple of hours. It's not the sort of thing you would regularly cut I just wanted to show the capability.
