Posted - 01/12/2020 : 2:19:16 PM This thread will be about the layout I’m going to build or should I say try to build? As I build the different sections I need a place to keep all projects together so I can remember what I’ve done and post the next update to. I hope to tie all the loose posts I’ve done so far into this one thread.
Unfortunately I couldn't get everything in the subject line. Here's what I wanted to post.
New York, Vermont & Northern Rwy. - Route of the Black Diamonds

Posted - 03/24/2021 : 4:37:18 PM Way back on page four I ended with the first wall laminated to the chipboard. It took me a while plus a few distractions to finally cut some openings in the wall. I drew up the wall in my CAD program, printed it out and taped it to the outside to help locate the openings. On the prototype building it looked like they were just access doors to the equipment inside. So two pics.


And the printer resin showed up today. Guess what I'll be playing with the rest of the week?
Also plan on a trip to see a fellow forum member Sat.
Until then.

Posted - 03/20/2021 : 3:37:18 PM Wow, it's been three months since I posted anything on my rock crusher project.
Here's a little update. I literally took the express elevator down the 3D printing rabbit hole. I accomplished what I set out to do and will be getting back on with the project.
I did a quick thread on the 3D printing I got into the last three months and have posted a link to the thread.

Thank you Tyson, much appreciated.
I was contemplating my limestone wall subject while heading for the mail box yesterday. I was thinking of taking a field trip west to Leroy NY to the limestone quarry there for some stone samples to bring back home. As I was walking up the driveway looking down a rock about 2" in size caught my attention. Picked it up and looking at it I came to the realization that I had ordered two truck loads of crushed gravel for the driveway and they come from a limestone quarry only about five miles west of me. So by the time I got back from the mail box I had a collection of rocks in my pocket. (I know what your thinking, this guys got a collection of rocks in his head.[:-bigeyes2] ) I gave them a quick wash, then dried them. Here's what they look like in case you haven't seen 2" rocks. 

I'm thinking I can incorporate them into the limestone quarry scene. I was wondering why they are so dark in color. Always thought limestone was more light gray. So down the rabbit hole I went. Discovered there are different types of limestone depending on where it's quarried. While researching I came across much more information on how limestone is quarried and sizes. So another question answered in my limestone quarry build.

In my hast to cast the rock crusher bin walls I used the wrong set of masters I had made some time ago. After I had milled them out I saw that I had not done a good job in drawing them in CAD. So I corrected the mistake and milled out four new ones. I had actually forgot to do a fourth one on the first milling job.
So I found the new ones sitting next to the mill. I had milled them out but never cleaned them up for casting. The pictures below will show what went wrong. One of the openings, the red dot on the Plexiglas masters and the red stars on the mold is bigger than the other three. They should all be the same size for a symmetrical look.


So I'm in the process of building a new mold box. Also have to order more RTV. Now I can also make a mold for that augur I'll need.

Your stones look very real. You’re on the right track.

Posted - 12/26/2020 : 5:28:34 PM If this was February I'd say the bullet holes were from the St. Valentine's Day Massacre, but this is still December. So it must have been Bastogne.
I like it Bernd. |

Posted - 12/26/2020 : 3:38:12 PM Practiced a little "rockfacing" this morning. Really didn't feel like getting into any heavy modeling.
I took the scraps from the rock bin walls and did some chipping. The bottom two rows are yellow dental stone cast from that commercial wall I was going to use to copy those rockfaced blocks from. The white is either white dental stone or Hydrocal, and of course the yellow dental stone.

I then got some acrylic grey paint and gave the wall a wash. Probably need to go over it again to darken it.

So the question is did I get close, not so close or very close to the commercial wall casting? Be honest. I've got thick skin.
I did notice that the yellow dental stone once fully cured was hard to work with. So I'm either going with the white dental stone or Hydrocal. Also need to determine block size, depth, width & length. Anybody got any ideas? From what I gather from the videos you can order any size block you want. More experimenting is in the future.
Oh, those holes in the blocks, there'er not bubbles, there bullet holes.

Posted - 12/26/2020 : 11:45:48 AM Interesting work, Bernd. Watching those videos, I didn't realize working limestone was that easy. I'm reading a book on how medieval gothic cathedrals were constructed. I'm really impressed with the skills of stone masons.

Bernd,
It appears that your roundhouse project has become a Sisyphean effort. Just be careful to get out of the way when the stone rolls back downhill. It will rough you up whether it’s hydrocal or dental stone.
Mike
I heard of that term before, but had to look it up. Well, unlike Sisyphean I've got square stones. They don't roll. I little tougher to get up the hill, but will stay put when left alone. I will reach the top and have a finished roundhouse sometime in 2030, maybe 2050. Don't know yet. You have to be careful with dental stone, it has a tendency to bit you.

By the end of this quest you will be a full fledged stone mason. Looking better all the time.

I started my apprenticeship in 2000.



Do you think that after 20 years I passed my test? 
I did a majority (90%) of the brick work on the house. Learned a lot about laying bricks, including keeping a straight line both vertical and horizontally. Now I've graduated to building HO scale block/brick walls. Might even learn stone carving.

Thanks Carl. On to phase two - creating a master pattern.
