Alteration of a cheap Chinese drilling machine.
1. Preservation of the column and lift table
2. Drainage system for cutting fluid

Onoff's printed former is the solution for version2, photos hereBeen running Krams electric melter design through my mind for several days whilst I've slept . I've been trying to work out in my head how the element can be successfully held in a cast in spiral grove that will retain the hot element and not sag like most of these home made electric furnaces seem to do .
I now have have this vision of pulling out the tightly coiled element to five or six times the diameter of the inside of the melter , wrap it in a couple of thicknesses of painters masking tape so it forms a long skinned worm then wrap it round the outside of a plastic paint can say 175 mm dia or so & in the same tape but as a smaller width adding a simple taped in loop every four or five inches so it hangs freely against the side of the can , gently feeding in the the worm of element so it's like a helter skelter round the form then put it inside the gas cylinder ( hole inthe bottom for draining accidents into a deep sand box ) & set it on some previously made & cured stand offs . add the input holes for the power Then pour in a runny cast in the gas cyl I've tried to make a gas burner from .
It didn't have a big enough entry throat and the jet I made was far too big so you could smell unburnt oily gas when it was on full belt & roaring like a tank without a silencer but only got hot enough to melt munz metal .
Leaving it to dry for a couple of months this summer then use my massive gas weed spanner to burn out the can and tape so that all is left is going to be ash around the element which should be easily taken out with compressed air and a bit of care .
Any comments as to the viability of this idea ?
Just make one yourself lolIts a purpose made inch drive petrol nut gun, its a beast of a thing for undoing truck wheel nuts

Solved the problem of drilling with small diameters from 1 mm. It was impossible to do this on a Chinese machine. Bosch drilling machine with 2 mechanical reduction speeds + stepless speed control + new German chuck provide the required accuracy + versatility + mobility in a complex.I really like that
can imagine a mag drill on a stand is really handy
It’s a devlieg not a mill!!!Now show us the square you used to check your mill is square and up to the job
