We finally had some decent weather last weekend so I could rub off the worst of the paint and try again. A bit better this time.

The saw is finally finished:



It cuts square and true:



The display can't be seen in the last picture, but I posted it to show it cuts parallel. I think it was about 0.5mm with no special attempt to cut really thin.

As for the spreed of cut - it took 2 minutes and 15 seconds to go through a 20 mm round bar on EN3. Probably quicker than I could do it be hand.

I put a video up on YouTube to show it running:


It sounds much louder in the video than it really is.

I then tried some 2 1/4" aluminium.

This took 17 minutes to get through. I appreciate it is much slower than a bandsaw, but it is much quicker than me - I have been thinking about cutting a bit off for weeks and have got nowhere.


I need to look up the duty cycle of the motor. It reached 60 deg C and it is baking hot in the garage today.

The cut is not quite square, but again far better than I could do by hand.

Have you used 18mm AF hex bar as per the drawings?

I did. I remember it was not easy to find and I had to go with EN1 leaded which probably is not ideal.

Thanks IRT.

I've found it in a few online metal stores as "0.710″ A/F BRIGHT MILD STEEL HEXAGON".

I'm based in Athens, Greece and sadly none of them post overseas.

I'll have to check the drawings and see if 17 or 19mm is possible.

Hi Toneless, M-Machine, mentioned above, posted to me in France, no problems.
