Question some basic milling questions

Hey i'm a hobbiest so i have no training in milling. but i was wondering where you can buy pieces of metal like aluminum blocks and stuff like that and also what is the best way to cut metal like that are there special blades for normal saws or do you need a special machine. any help as to answers to these questions and where to find general info would be much appreciated thanks in advance

well I hope this helps

Okay,

I buy all my aluminium , brass, and SS at a local metal supply house called the Metal super Market.

For plastics and derlin I oder it in from www.smallparts.com

Now as cutting go's, I Use a milling machine built for shapeing metal cost between 1000$ to infinity for these beasts.

In the milling machine we use bits called end mills.

Umm, lets see, then there is the lathe for turning cylinders of metal/plastic or woodd , and again they run from around 700$ and up.

Hope this helps, and if you have any more questions jsut ask.

A few years ago my school decided to get rid of most of the metal working machines/tools (apparently people don't need to know how to use machines), but one of the teachers got a few to stay. He is showing me how to do some things on the vertical mill, lathe, and some little electronic lathes/milling machines that work from a CNC program (but can cut only sheet metal or plastics).

Could I mill gills into the feedtube on my PGP using a vertical mill, or is that always done by the really expensive mills run by computers? Just wondering how accurate I could do the job...

BTW, how tough do you think making a bolt (say, Blazer) would be out of Delrin? I am looking for some projects to do...

Well, for sure

For sure,

The standard vertical mill will cut slot into the top tube all you ahve to do is set it up for the cut properly .

you don't need CnC to do everything, all CnC really dose is make production work easier, and wild milling paterns easier.

and Turning derlin as far as I can tell isn't all that hard, except its solf and cuts fast, but I am sure you could build a nice blazer bolt .

Well, started making my custom dropforward yesterday, worked on it for a bit after school.

I could never find a d/f that would suit me, basically one that owuld extend out a lot and drop down at a certain angle, but wouldn't place the tank too low.

I never knew milling aluminum would require so much patience, but it is my first time... After this I plan on making a cool barrel plug for my Nova (none fit it, the barrel moves so it shoots it out), delrin bolt for a Blazer, and maybe a d/f similiar to the CP flame ones.

It should be done some time next week, and I actually get some extra marks I can honestly see myself doing custom paintball work for a living, like Punisher... it's just SO cool

Will do, I'll have to scan them though, have them by tomorrow

Just have to file the dropforward *by hand* some more, to get rid of the slight marks from cutting before I polish... takes so long
