Joe, I went hunting at the home store (Lowes) for black iron pipe as it looks like all your designs call for it. The pipe I found looks like it is either painted or plastic coated BUT was badly pitted or bubbled. In any case, it doesn’t look like a very good surface for the bearing to roll on. Next to the black pipe was galvanized. Is that a good alternative? Is it the same O.D., same strength, stiffness, etc.?

Yet another Lowes investtigation.....

i am confused aout all the references to MDF. when i think of MDF i think of THIS stuff:

isnt it actually partical board that most folks are using:

MDF seems very papery to me and prone to tearouts. I am probably confused as usual. Just looking for some clarification.

Thanks.

How well does MDF tap, and are there any tricks?

Also, any suggestions as to whic dap and die set to buy?

I started my cnc machine from the drawings you sent. I got a good portion of the x-axis done. All is well execpt now that i am on the x-axis bearing brackets, I can not fine 1 1/4 aluminum angle ANYWHERE!!!

I hit Home Depot, Lowes, and even the local hardware store. NO DICE.

Any suggestions?

you have to get it from an alumn. distributor in your area, ...

Joe

Joe,

Where in San Antonio are you located?

hi, i just found this great site, i actually came here to this topic from google.

anyway, i thought this would be as good place as any to make my first post.

i am in the UK, so, unfortunately i can't order the kit from you really as the postage would be prohibitively expensive. However i do have access to a “real” CNC machine at my collage (well actually school really). So i was hoping you wouldn't mind sending me the DXF or solid edge files along with a quick guide on what parts need to be machined in what materials, along with the construction guide.

My email e-mail address is calgar@*nospamplease*cybiko.eu (without the “*nospamplease”) i don't make it public on forums to avoid spam harvesters.

Thanks in advance!

When I found this forum, till then it never occured to me that it's possible to make your own CNC mill. I've been working on 3D surfaces and my current project is a 3D USA flag. It is 40' by 40' by 4' tall and I was wondering if there are any plans of a taller mill? Well, not one of that size, but something that can do tall complex curves. I may "borrow" some wood from my school to make this and when i'm done with college I can complete it.

joe can i get the drawings of ur cnc machines 1-3 or as many u have made master! ;P
send to skalhus@spray.se
damn im gona try make on now.
i live in sweden little smaller market to find the stuff butt ill try!
the controller card for the y.x.z motors u hook it up to the pc directly?

err will cost me 70USD IF! i buy it! ;P

Here is a complete list and people can choose what they like depending on their built level

I'm looking forward to your feedback, Let me know what you think.....

1 - set, Tool Holder for Rotozip Upper and lower = $20.00 (does not include bolts)

1 - set, Nema 23 motor Spacers 3 total = $10.00 all three

3 - sets, Lead Screw Bearing supports = $30.00 (Does not incluse Bearings)

3 - sets Anti Backlash Nut w/ Tensioner = $15.00 (Includes Nuts 5/16")

4 - Small Adjustment Blocks 1" inside Dia. = $16.00 (does not include 1" adjustment bolts)

4 - Medium Adjustment Blocks 1.25" inside dia. = $16.00 (does not include 1" adjustment bolts)

4 - Large Adjustment Blocks 1.5" inside Dia. = $18.00 (does not include 1" adjustment bolts)

6 - Linear Alumn Bearing Block Suports = $35.00 for MDF and $45.00 for HDPE (3 sizes 2 ea., 8", 7.5" and 6")

Linear Bearing Slides 1 1/4" angle, with 4 bearings = $18.00 ea. (total 6 needed, 8", 7.5" and 6")

All the MDF pieces cut for the main structure only and ready to put together = $250.00 (Does not include Cutting top or very bottom two alignment pieces)

All pieces cut in HDPE for the main structure only (High Density Polyethelene) = $500.00 (Does not include Cutting top or very bottom two alignment pieces)

Remember prices may change slightly (but will hold on order date) depending on if i actually loose money in time and materials as the proccess goes on, as it is i am loosing or breaking even to start. The more people i have the more i will be able to get quantity on materials and drops the price for me initially
Thanks, Joe

Thx mt good work!
Did u find some blueprints for ur first models?

gona make a small first using printer steppers. how small a printer uses 100oz steppers u think?

here is a pdf of my steppers check em out

right! they have a gear box on em make em stronger i think!
dont shows in pdf

the motors have been cutting metal on the rig it`s on right now!
so they are not to bad i think the gearbox on em makes them stronger
