    Looking forward from my seat in the second row...to what comes next.

    Re: question, I’m surmising soapstone doesn’t come in wall sized pieces...or it’s too fragile or heavy


    I've seen the foam technique used here and a few other places. It does look nice.

    There'll be an intermission some where along the line for refreshments.

      Simple, because you want to make blocks.


      Well, you are partially right there.

      Ok, here's your answer, and the beer's on me. Note the variegation in the green circle? When laying blocks nobody is going pick through the big heavy blocks and match the variegation. The bigger the piece the more noticeable it would be.

              Nice project Bernd! You might try balsa foam. You would be able to incorporate both rough positive cast stone and quoin corners in a single sheet.

                Thanks for stopping by Philip. I'll be looking at the technique when I get to building the roundhouse. For now I'm going with cutting up the soapstone into blocks for the rock crusher building.

                  I have always wanted to do a project with soap stone! Seems the only available stuff is for marking steel.

                  I'll be watching!

                    Check out Dick Blick. That's where I got my larger pieces from.

                      The first experimental pieces have come off the mill.

                      But first, I did a little more research on block sizes. The standard concrete block size I’m going to base these blocks on are Actual size 11 5/8 x 7 5/8 x 15 5/8 Nominal Size 12 x 8 x 16. My blocks are going to be 14” X 14” X 20” Remember the quarry company could make up its own sizes. Being the companies CEO, that’s what I decided on from what my architect had said.

                      I got much information from the Indiana Limestone Company website.

                      A view of there yard of limestone sized rock.



                      Here’s a chart for what the Indiana Limestone Company sells. These are standard blocks for a running bond.



                      These are the sizes for a “stretcher” row.



                      So this morning I started out by setting up the CNC mill. I glued some aircraft plywood onto a MDF base to hold the slab of soapstone from being pushed away. I used a climbing cut which also helped hold the slab down and push it against the stop. I’ll take a video of this process next time around. For now here are some stills. The mill got pretty dusty cutting 16 slots or pieces.



                      This gives a view of the slots milled in the wood. The other cuts in the wood is from cutting out some acrylic plastic for the rock bunker mold.



                      And the first bars of soapstone. They are .160” square.



                      I placed a penny on them for size comparison.



                      This is something you’re not going to do free hand and hold accuracy. It took a couple of hours hand coding the machine to cut these.

                      Up next is making a fixture to cut them to a length of 20 scale inches.

                        Looks great. Yep, it looks easy to the casual observer. Takes a lot of time doing the setup, but the results are awesome. Are you building a fixture to cross cut them in a batch of 10 or more? Fun stuff!

                        P.S. 90% or more of the buildings in the Capitol in D.C. were made from Indiana limestone. Those quarry's are humongous.

                          Wow Bernd. Amazing.

                          Maybe I missed it. How large a piece of soapstone did you get from Dick Blick?

                            You are amazing, Bernd... nuff said!

                            Excellent! work and craftsmanship..and you once stated you would take a seat to watch me build structures?.. I think you have surpassed that day...

                              I think once everything is laid out as to how it's done it'll be easy to understand. The process of making model blocks is no different than making the real thing. My next post will explain how I'm going to do it.

                              Ya, I was surprised how big. IIRC in their literature it said 4,500 acres.

                                The sizes I got varied in length by 3" square and there were four pieces. One of the members asked where he could get large pieces like that. When I went to the sight they had varied the sizes from when I purchased mine over a year ago.
