Materials used in CNC build projects

[Ross77]

Sometimes your keyboard is faster than your mind in your eagerness to help, that's all

:rofl:If you knew how long it takes me write a post then my mind must be slower than a snail on national go slow day

I certainly dont know everything (but I'm keen to fill in the gaps) I just try to look at things from a practical point of veiw as well as pages of theory and calcs.

My logic was that vibration can only be transmited through a stiff material. If you take a steel bar and tap one end then vibration is transmited to the other end, but if you took a similar bar of say rubber or wood then much less vibration will be transmitted.

Therefore only a stiff structure can vibrate, No?

Anyway its getting late, Any good books you can recommed for me brush up on this subject?

I would look to get some large pieces of Ally to melt as the smaller the pieces the more oxide you will produce.
Ideally you need a reducing atmosphere for ally not easy with propane as you need a lot of air to get the temperature.
I would like to try but not enough garden(boss has too many plants)

Hi Peter

I don't think you have looked into this as much as I have?

You melt down all the small stuff together and mould decent sized? ingots out of them ready fo melting the components to be made.
The ideal Aluminium is the type thats already been casted before ie cylinder heads or any large casted component as this will be prime material.

As for Propane torch,there is lots of source out there in constructing a torch head to give maximum heat flame within the homebrew furnace,believe me its so simple.

Follow this guys series of making his own CNC,everything is home made/built/casted,such a pity he didn't have the brains to protect himself for safty when casting though.
