my power hacksaw

[shipto]

Sorry no detailed build pics just the (almost) finished machine. I decided that almost everything I am doing in the shop involves cutting various bits metal to size so I put the carousel on hold to make a power hacksaw.
This is has been a bit more of a pain than I foresaw I tried a single pivot point for the drive and arm movement first and didnt like the results so I gave the both movements their own points and it works much better that way.

Cool machine!

Very nice can it raise as it goes forward or just slide back and forth? I just bought one it's a  great captain the lifter wasn't working right but after cleaning and new oil works fine. The lifter itself is quite simple if your interested.

no Tom its just a simple back and forward machine I suppose adding a lifter for the back stroke wouldnt be too difficult but I was in a hurry to get some stuff cut so went for simplicity.
I am planning when time permits to build a larger machine that will use the larger 350mm blades maybe I will fit a lifter to that one but thats far in the future, my next project is going to be a jacobs gear hobber and I will try to take better progress pics for that one.

I've wanted to do that project for years! I've collected and saved all the old issues of ME which had references to that project in it.

well really i shouldnt call it a jacobs because that is built with a set of castings I will be making mine up as I go along

T D Jacobs hobber wasn't built with castings, it was all fabricated.

I wouldn't bother with a lifter - my Rapidor doesn't have one; the backstroke cleans the cut out, it also means it doesn't (technically...) matter which way around you mount the blade, I suspect convention means putting the blades facing forwards like a regular hacksaw.

Mine tends to build up an even-ish pile of cuttings either side of the cut.
