New CPU-WB (nuthin fancy) pics
 

I had to play a little bit more to stop the depression I got after destroying my gpuwb...I don't know what to do over the core...hmm...anyways, here it is:

Did you centre the input on the cpu core?

Nice Job BTW, what mill did you use?

Thank you hara :) The input is over the might core, yes.

*checking for picture of my mill*

TADA! this thing ROCKS! couldn't be more happy then I am with it

oof,
looks cold out that window.

OMFG , is that a window , i was thinking it was a picture , heck yah it looks cold . .hahaha.. --Bikr

hahaha! The picture was taken this winter ;)

those small channels at the centre will increase the performace by alot. adding a lot of turbulance. keep us updated chrion and keep it up.

I am more impressed you did that with the hand wheels than anything else. Nice work!

That's why I asked what mill did you use. Did you really use the hand wheels? C'mon don't cheat, tell us! :D

Its handmade, with my new rotarytable...

thanks for the feedback!

damn good job for the first time using that table.

The only thing I didnt like about manual milling was the fact that it was almost impossible to get an even finish on the bottom, when moving to another channel, that cant be cut in the same pass. Thats why I decided to go with CNC....Plus Im lazy and it sure beats the h&ll out of standing in front of the table, turning handwheels for 3 or 4 hours!!
All I gotta do know is man the Estop button,and the 40.

Chris......did you ever check out that yahoo group I told you about, when you were inquiring how to convert the Z axis on your mill??
Whats the make and model on that thing? Ill see if I can dig anything up specific on it.

with oring

thats why i sandblast it. I can't see those ugly leftovers from the mill...

.

A tip about the o-ring groove/channel: it must have three sides, and you can't sandblast it, because you're just helping making sure that it'll leak. ;)

i agree with ben, i think that the o-ring groove is too close the the outer channel of the block. Make sure that there is enough space for the wall not to collapse under pressure.

Definately too close..Ive never had good luck with anything closer than 0.06" to the channel and not collapse.

Actually, there is no wall. An o ring is not meant to seal that way.

ohh $hit, i thought that ther was a very thin wall, ok i am going to the optition right now :rolleyes:

so i have to agree more with ben and hara, i think that that o ring is not going to seel the block.

I dont get it...??? why not?

I dont sandblast it anymore...ive learned

If you don't hold the o-ring with a three sided groove, then when you compress it, as you screw down the top, the o-ring will compress into the block, instead of compressing up against the top.

This is a surefire way of having a leak.

I'll be using a 1/16" o-ring, which is going to be more than plenty for the job, but the o-ring groove has to be perfectly smooth, and the o-ring has to sit in the very middle of it.

I had a very difficult time with my block and the o-ring, because I didn't have a lot of room for that groove. On the plus side, I'm bolting the top, with no less than 8 screws ;) (six would have done fine, but my design can't handle 6 bolts!)

Ok. so I'm fücked? Cause I've seen blocks doing the same thing. I will prove it doesn't leak. I won't leak either.
