Show"N"Tell ( Your Machines) / Re: Upgrading to linear bearing system advise!!!!!!

Q- Will a 16mm bearing block and 15.875mm aluminum rod work and fit fine?

No. Not at all.

I would try here for your needs.... http://www.pbxbearings.com/

If you need the shafts cut to a particular length, you will have to have a thin grinding wheel, a die grinder or chop-saw, safety glasses, and some common sense.

Good job Hood. That lathe sure is quiet, compared to some I've ran. What type of coolant you use? Looks like some oil based similar to what I have used in the past. Was great stuff, until you need to change it out. Being so close to the waters edge, I don't suppose you have much of a problem getting rid of it.   Have you tried the vegetable based oil? Thought about getting a gallon just to try it out.

I don't have any info regarding a screen, but the least I can do is compliment your work. Looks like a quality job you've done there! This certainly doesn't appear to be your first machine project. Thanks for the pictures!

G-Code, CAD, and CAM discussions / Re: Example of using the L Repeat and Incrementing Z movement

« on: February 23, 2012, 03:44:53 PM »

I see that you've specified a Z offset value, but I don't see where you've actually raised the Z axis to clear the part. All you've done is created an offset and then cancelled it. Instead of using a temporary offset, why not just go back to incremental , specify a Z distance to clear, absolute back to start, increment back down the same amount you raised it.
Such as...

G91 Z1.0
G90 G0 X-27 Y-47
G91 Z-1.0

There's probably a hundred ways to get the job done, and really it just boils down to what you get accustomed to. Personally, I won't use an offset if I don't have to.

G-Code, CAD, and CAM discussions / Re: Milling the table

« on: February 19, 2012, 12:34:11 PM »

If you do decide to mill the table flat, I would still mill the spoil board flat when attached. If you have never cut aluminum before, you might end up with more problems than 0.5mm. There's nothing super difficult about it, but a bit of experience with it won't hurt, either.

Is it a common way to get X-Y moves parallelism with the table ?

Absolutely. In fact, If were to see a spoil board NOT faced off, it would strike me as rather odd, or perhaps "rookie-ish".
