Tangent Corner / Re: Avitar wont animate

Weird, it will animate in the post but not in my avatar either.

Possibly it has to be the exact size of the avatar itself!

Sorry I couldn't be of more help-

Hi Rich,

Thanks for the info as well but since the plate was not finished, I don't think you might be understanding what I'm doing as I wasn't descriptive enough, or I just don't understand your reply, lol!

The cross slots you see will be filled with an o ring material to "block-off" a certain area. Much like the picture of a vac grid I've seen before. The main hole for the fitting will be in the center on the side (long section) and a 1/4" hole will go down from the top surface to the main hole for the fitting to create a "channel" that will reach out to all slots until they're blocked off with the o ring material. As I mentioned, there a lot of ideas I have this such as hold down screws for blocking in parts so they don't shift on me.

Here's a larger scale plate that I've seen but made for a router table:

Thanks, fellas - 

Have a few questions.
What is the gasket size & material and where purchased?
Have you considered making a generic plate with numerous holes yet?
Anything to consider when porting the base in terms of volume?

Rich, the gasket material I use is Viton AS568A Aerospace Standard  1/16th "O ring" material and I leave it about .002 above the surface of the aluminum. The O rings run oversized so get the oring material before you start machining - 

As for the Plate with random holes, funny you mentioned that as I'm in the middle of desgning one at the moment. It's not done as obviously there's no holes for the pump as of yet but you'll get the idea from the pics below - (pay no attention to the sheet metal pop up balloon up on the left. I had my cursor over that function when I copied the screen shot -  )

As for porting the base in terms of volume, since I'm not a math major by any means, I have read that the more area to create the vacuum, the stronger the pull. I experimented with abs plastic first and came up with the design you see as it worked perfectly for me. 

Hope that helps!

Thanks, RC, I read through the complete thread and it's interesting to see how everything is evolving. Got some of the examples and played around a bit today and even found some ways to end up playing in Mach Turn and crashing my PC a few times. Not very stable just yet, eh? lol!!

Ah well, it's fun for now

Thanks, RC, I guess I will be keeping a sharp eye on LazyCam for now and just hope something happens fairly soon. Do you by any chance have any example dxfs for turning that I could load and try out?

Thanks again for your time-
Dave

Can't argue with success, and that's just gorgeous. I'd be making medallions in my moulding all over the house....lol!

G-Code, CAD, and CAM discussions / Dxf desgn for the Lathe?

« on: June 26, 2008, 06:50:00 PM »

Ok, so forgive me but I'm not a CNC lathe guy, heck, I'm barely a CNC mill guy   but I will be attempting to put together a CNC lathe in the near future so I need a bit of info/help here if you don't mind?

 I have no problems drawing up a dxf of a part for the mill, yet, I'm not sure how to start to draw a dxf for the lathe. Am I to just draw half the diameter/profile and then import that into my cam program?

I will be trying to use "LCam Turn" but I'm honestly not sure where to begin. It's funny, I've been a "manual" guy for over 20 years and when it comes to some of this design stuff, I'm a complete idiot lol!

Thanks for your help-
Dave

I believe I asked this once before and the answer was no. I would like that too-

 Sorry -
