Excellent casting work Thanks for sharing ? John

One of our local guys has lost foam with the floating sand bed down to an art form. He uses his JGRO CNC router to create the patterns out of foam. And used it for production casting for a while. I

Green sand or Petrobond, no, I can understand why you wouldn't want to mess up your sand. However, there are folks doing it with plain sand, aerated with a blower until the pattern is sunk to where

One of these days I'll get around to casting this mount for my harmonic drive. It pulls from the sand nicely. Drawn with Alibre CAM. Fitted to the motor. Then tapers and draft added and expanded by 3%

Excellent! Thanks for including the photos. I got the idea from your description, but photos are better. Sometimes my brain sees things that are not, and other times is doesn't see things that are!

If I ever get a printer that will print metal objects, I just might do that! My interim plan is to learn to print stuff I can use as patterns for sand casting molds. I've got a number of projects

I had some acrylic parts to my 3D printer that were broke when I received it in the mail so I decided to make replacements out of 6061 aluminum. The first pic is the stock piece of aluminum I got

I downloaded all of them I could find, and ordered the ones that I thought I could actually use in dead-tree versions, too. The only things I didn't order that way are the ones for wiring and motors,

I”ve gotten a couple as well. I was just quite surprised to find them on Archive.org <http://archive.org/>….

It's not all of them, but it is all up to #39, which is pretty nice. I've got most of them. You can order them direct from the publisher for (last I did it,) about $10-15 each, or though Amazon. I've

If all you have is a lathe; depending on the size of the plates, and if you have a lathe faceplate you can make a big flycutter our of it. Mount the work on an angle plate affixed to the cross s lide

How large are the plates? The usual method for reducing thickness is fly milling. If you own a shaper or planer you could possibly use that, as well. Both of those methods work best on relatively

What size plates? Where are you? What do you have available in your shop? Ralph [email protected]> wrote:
