whoa, no one ever noticed my feet before...

Must be a podiatrist.

Actually, I got those feet out of a dumpster. They have a big-ol ball bearing int he middle that supports the load when they...

Pretty!

Which CAM package are you using?

I've been using my mill quite a bit - love it.
The time has come for CNC. I spent quite awhile mulling over an approach and finally settled on a plan.

ya well, y'all drive on the wrong side of the road too. :)

spin casting is highly specialized, someone asking for shrink info is probably not heading that route.

Trust me guys, use 5/32" per...

that's so small of a dimension you can pretty much ignore the shrink.

if you're going to do much pattern making, it's wise to buy a shrink scale for the metal you're working in.

if you use CAD,...

That would be just a little under 1/8" per foot, for sand casting in aluminum using the typical sand casting alloys, you'd likely come up a bit short on castings over 6 or 8 inches... (15.2cm or...

Sweet! Send us pics.

Here's a link to mine:

Find a smaller roughing bit I guess... 3/4" is the biggest shank that will fit in the 2UVR as far as I know.

The Type Z collets are out there but the popular sizes are indeed hard to find.
1/4" 3/8" 1/2"... they're tough but everything else is easy, on the other had they can get expensive.

But here's...

Count me in, I'm in Mira Mesa.

Aluminum is sometimes said to shrink 5/32" per foot, sometimes they say 3/16" per foot. Either will work just fine for home casting.
Shrink scales are commercially available, sometimes you even...

I only hand code, but it's not by choice.

practically all of the machinging I do is on the castings that I make. I've not been able to find a cam program that works for me yet. All i'm looking...

I'm in the same boat, have solidworks and trying to get to Gcode.. even just 2.5D
Solidcam might do it, but it must be real expensive since no one will say on a web page what it costs.
Kinda...

X and Y are easy, of course. I'm planning on designing new castings for the ends (I was a patternmaker in another life and have a foundry) Z is going to be a...

Thanks for the info, I was beginning to think no one knew or cared.

I have a copy of a manual of sorts, it's not the easiest thing to dechiper but I am completely capable.. I'll look into it as...

I tired posting this once and for some reason it comes up blank so I'll try again.
I've got a 2UVR that has a problem with the powerfeed. The rapid traverse works fine and if you wiggle the handle...

Anyone know how to adjust the clutch in the powerfeed on a 2UVR?
Mine's working, sorta. the rapid feed works fine but the normal feed is iffy, happens at any speed selection. sometimes it works if...
