Building a milling machine

<< < (9/44) > >>

Arbalist:
Actually I did see a thread somewhere where someone used old steel fasteners as part of the mix for their mill.

chipenter:
Strong concrete a mix of 5or 6 to 1 the smaller the agregate more cement is needed to cover the gaps , and should go a very light grey almost white .

NormanV:
Sorry Jeff but you are speaking to a thicko here regarding concrete. Could you explain more fully please.

NormanV:
For the platform that supports the x and y axis I had originally planned to make an aluminium casting but I soon realised that would give me two large flat surfaces to level off and to get at 90 degrees to each other. It would also be too big to fit on my lathe to machine it. Instead I bought a large (18" x 12" x 8") angle plate that would give me the built in accuracy without any problems of machining it. All I had to do was to cut it in half. This I did with my rubbish angle grinder which burnt out under the strain (thank heavens for a two year guarantee) and a hacksaw for where I couldn't get the angle grinder to fit.
Here it is before I attacked it with the hacksaw.

NormanV:
This machine is getting quite heavy now and when I fit the table I will not be able to lift it. It is time to build the bench upon which it will live. I had originally planned to make it from metal but that would first mean that I would have to buy a welding machine. The cost of that combined with the cost of the steel made me look at timber construction. I have built this bench using 3" x 2" timber for the frame with 1/2" particle board for the cladding. It seems very stable but time will tell. At least I have got somewhere semi-permanent to keep it for now. I will be giving it a coat of paint to make it look a little better and I'll get some handy storage in the sides.
