Thread: clever diy hacksaw idea - woodworkers might like this too

None actually, normally I take two in the morning and two at night; but, I couldn't find any, you blokes appear to have overdosed leaving none for me!.

Google, Homemade Power Hacksaws, there are some good HM machines shown.
Also there are 4 PH for sale on Ebay at the moment.

Presumably you would also consider the Stirling engined coffee mug fan to be a serious attempt at a cooling fan and a domino demonstration as a true feat of engineering excellence - extraordinary.

Sacc,

Thanks for the response.

A few people have pointed out that this would be a fun project, not a serious tool suited for a serious machinist.

Unfortunately I have not yet acquired the skills nor the knowledge to assess these things as well as all of you experienced people, am happy to confess ignorance and learn.

Are there any home made hacksaw designs that you could recommend for an enthusiastic but unskilled newbie who would like to make one, acquiring relevant skills and learning along the way ?

All of the things I do in my shed are for fun and learning, and I doubt that I will ever become a heavyweight machinist.

.............. and ironically, you picked it, am happy to confess my interest in building a small Stirling Engine, purely for entertainment and learning, I think they are fascinating and have acquired several plans.

how about this one?
May even work with a sharp saw and properly tensioned, ha ha

I think most who responded to this post would be a better source of information on PHs than me, I've used PHs but never actually owned one. I replaced my third drop saw with a bandsaw a few years ago, best thing I ever bought, aside from the chocolate I'm about to eat!

I think for the money you'd pay for a good PH, you could probably buy a new bandsaw.

A PH wouldn't be difficult to make, building a good, accurate one is a different matter. I have seen homemade PHs for around the $150 mark on Gumtree, but most are pretty rough. Still if you are determined something like that could provide a good base to build on and play with. You can only learn from your mistakes and if you make enough of them???

Phs were once everywhere but have mostly been replaced with bandsaws, for good reasons. PHs are very slow, very heavy and probably better suited to cutting large sections of solid stock, so depending on your intended use,you may be better served with a bandsaw.

Good luck with your Stirling engine, I designed and built one years ago, it sort of worked but I gave up in the end Hope you have more luck than me.

PS. If you do a search you should find a few threads on this forum to do with restoring older PHs. I have read a few threads on this forum, but as I wasn't a member at the time never saw any pictures.

the friction blade was missing but I like the look of the carbide blade in the second half of the video

I would say that circular blades work better than square or rectangular ones
Was it a metal cutting saw or a wood one?
Model Engineers Workshop is running in the past couple of magazines an article on making a power hack saw, can get edition numbers if anyone wants details.
