It's getting on for Halloween, so I thought I would have a play making a tea-light.

Rather than mess with bits of thin stuff and bend it round to shape thought I would have a go with some left over square tube. This stuff is 70 mm box (2 3/4 inch), 12 gauge so around 2.7 mm thick.


I would need to sort out a jig to accurately centre the cutting , but it will do for now. Bit of a pain cleaning the inside as space is a restriction, so soaking another piece overnight in Hydrochloric acid (muriatic) to see if the stuff just drops off. It was better after I remembered to leave a scrap piece down the middle so cutting the top did not blast the inside with dross.

Anyway it was just a silly idea to use up scrap pieces, the images are I think bought in and made up so no dxf.

I went slightly larger in the cut area and centred the items better after comments from SWMBO, I basically played for an hour in the garage.

It's fun to play home made.

Good thinking there, like the shadows.
It's tricky enough getting cuts centered sometimes on likes of box, especially for those with a keen eye :lol:
I've been finding it easier placing the centre of the drawing on zero, zero in sheetcam and then same in mach lining up with a centre mark on the part.

I was at one point considering putting some laser pointers in the torch, but then thought for my use, maybe one day?

What I decided to try was to line up with the edge of the 70 mm box so I drew this sort of thing in Qcad

Done on two layers, guide lines on one and the pumpkin on another. It meant that X, Y = 0 was bottom left corner.
In sheetcam I only cut the pumpkin layer but I could line up just on the edge or as close as I could get.

Forgot to say that the overnight soak really helps in the removal process, 99% of the dross came off with a wire hand brush.
