i did a search but all i could find was junk |
Home Depot
http://www.plasticsonline.com/ |
I can prolly get you some, how much U need?
and does it have to be 4 inches? I have a chit load of 3x2.5x 3/8th |
how much Fixittt?
yo can i buy a raw spir@l block off you??? just needs to have the sipr@l milled i would make my own but the mills at my school sux, well more like the software and controllers they're running them in Dos :cry: |
well how many peices od acrylic are U needing?
I dont have any raw spirals machined, all the ones that are currently machined are spoken for, and then some :) Sorry, If I could then beleive me, I would |
Quote:
2 or 3 maybe that sux what program do you use to machine the blocks??? |
well for that small of a quantie I think that if you paid for shipping, I would not be terably hurt in letting U have them, just let me get my sheet cut up ok?
I drew the block is Smart cam a 2 1/2 d cad cam software, only about $7,000 |
trolling a post :)
do U meed them milled to size, or will a rough saw cut work for u? |

there is a machine shop in my school we have 3 big ass horizontal mills and a vertical one think it would be hard to make a circle? |
on a manual mill, yesssssssssss
on a CNC mill, NO PROBLEM! |
aaah crap!
the CNC's we have are messed up and are using torsim in DOS i think i'll have to borrow the manual :cool: i wish i could steal one of them :D :D :cool: those bastards running them on 640k of memory :mad: |
why are the dementions of the circles U want machined into the tops? maybe I can help U out with that.
I do happen to have a desktop CNC machine in my garage |
that's what i'm gonna do
but i need to make up the dimensions i have two copper block just sitting here waiting to be machined and hopefully i'll start this week the dimension of the circles is 18mm radius but there might be a change in design e-mail me: PetDMC@hotmail.com :cool: |
it would be best if U emailed me
as I am at work and pressed for time most of the time. fixittt@cimtel.net |
np :D
|
Well, I am getting some 4 in strip cut just for U.
So U can stick with your original idea. |

and with the circle making... @ school we have a vise that can be turned 360*:cool: for the manual mill but i don't think we have any bits for plastic, i know there's some for steel and aluminum :confused: |
Dunno about milling, but when drilling you use steel bits at a low rpm (100-500, to avoid melting the plastic).
|
the same for acrylic and milling, use a 1/2 in end mill at very low RPM should work good if the endmill is really sharp, remember you want chips coming off, not dust or melting plastic.
|
If you are an impatient bastard you can do it faster but you need plenty of cooling water all the time, like really flowing over it.
|
isthat desktop CNC machine U have at school a MAXNC machine?
Mine is a blue one EDIT: See that plastic box on the floor by the mill? UMMMM SPIR@L goodness!!! http://www.borderbuyer.com/fixittt/mill/mill.jpg |
the one we have at school is alot bigger than yours :D
we have two of'em one is like a old POS (the colours are green, looks like its from the 70's :D ) i'll try and get some pics of it i bet if you had the one we have you could make twice as many Spir@ly's :cool: BTW i'm at skool :D :D :p |
Pay attention in class, kid. :p
And don't forget to do your homework. :D |
