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.
