    Thanks Tom. Just like to share techniques and ideas. Hopefully some will get some use out of it.

    • Here's a bit more information on how soapstone is quarried and machined for consumer products. It's a five minute video. I was looking for it this morning but just couldn't find this particular video.

      And some soapstone history.

      https://geology.com/rocks/soapstone.shtml

      I wish I could use a coolant to keep the dust down but for the amount I need it's not worth the mess it would make. probably more so than cutting it dry.

      Once I have the blocks cut I'll be back on posting the procedure.

          Yes, it is. Apparently it has quite a range of uses, including medical, from what I’ve read.

          • This will probably be the last post on the "soapstone block experiment".

            I set up the mini-mill outside my basement shop with the shop vac and air filter unit.



            After about halfway through surfacing the blocks I noticed the shop vac wasn't drawing much air. Also discovered after a couple of minuets that the black shelving unit was collecting white dust. The problem was the vac was blowing out in a wider circle than the filter could pick up. That was cured by adding a couple sides to sort of funnel the air toward the filter intake. Note how white every surface is. The second filter behind the first one showed hardly any signs of dust.



            Here's a look at a new filter, left, compared to the filter on the right about half way through the surfacing.



            There was no dust coming out of the exhaust side. I'd put a piece of cardboard there and sprayed it with some spray adhesive. It showed no signs of dust. So I have to say this set up was a success and will be used when cutting the more soapstone.

            Next will be cutting the 3" X 3" X .160" slabs into long blocks and then cut to proper lengths.

                At this time of the year the whole garage is the beer fridge. Just the right temp. of 40 degrees.

                • that's some interesting progress you are making with the soapstone, however have you ever considered using Balsa Foam, it is really easy to carve. I make some walls just like the ones you need using only a small flat blade screwdriver to do all the carving, it went really fast. I don't have a photo of the wall I carved, I can take one this weekend. here is the front of an engine house I carved, it is more of a random stone, I only used a tooth pick to carve.

                  • Thanks Coaltrain. I've looked at the foam balsa but haven't given any thought to using it. Looks interesting. One thing I don't like about it is coloring the finished carving to make it look like real rocks. Could be it's because I've never tried it.

                    • This stone wall is balsa foam.

                      • Looks great Bob. Nice job on coloring the individual stones.

                        All right. I made a video showing how I cut the long blocks of soapstone. No animals were injured, including me and I still have all 10 digits.

                        • Hey Bernd,

                          Great video on the cutting of the soapstone slabs.

                          A simple procedure if one has the great tools that you do. Regarding the video, if I were doing it, I would use something longer than that small piece of wood you used, as I tend to "twitch" sometimes, and I would be very happy to have "all" of my fingers attached, including their tips.

                          • Interesting, Bernd.

                            I assume what I’m seeing is you simply holding the stone down while the machine moves the tool and the platform (platen?) automatically based on programmed instructions. Correct?

                              Thanks Rich. After 30 years of working in the machine tool industry working on operating machines I learned not to twitch. [^]

                                Yes you are correct. The cutter is revolving counter clockwise as you are looking at it. It's a "climb cut" due to the cutter trying to pull itself up onto the part being cut. The cutter is actually pushing the piece down onto to the table and back against the stop on the right. I'm just lightly holding the part down so it's doesn't vibrate and move. That would be disastrous if it moved.

                                The cycle is a simple rectangular move in a clockwise direction. Each cycle moves the cutter .180" to cut the next piece. Clear as mud right?
