Mike H., Jim, Jerry, Mike M. and Rich, thank you .
Jim-I noticed that they were sold out of many types too. Seems some other modelers already picked up on the rolling pin idea.
Mike M.- I've been thinking about some brick buildings in the future as well, just not sure if the "Dutch brick" style is appropriate for American architecture.
Rich- It seems I've started a tool movement. Though not absolutely necessary, but they certainly help! I even found a new plaster. I'll show it in my next update.

Mr. C are you saving the sanding dust to use as mortar to fill the joints or do you have another incredible plan?

Frank- Trying to "re-hydrate" the clay isn't fun. My incredible plan is to use fresh clay mixed with a little Elmers white glue to fill in any gaps.

Excellent work Carl. Nice engineering going on with this build to get it just right. The 45 deg sanding jig is a great idea. Nice carving too.

Carl, Read thru the build. FUN! Thank you for the tips, techniques, and tools! The castle is coming along nicely. I used to play D&D in my youth.

Thanks Jim, but the walls are Das clay, only the tops (battlements) are plaster.
Scott- Thank you, and welcome to the thread!

Wonderful project Carl! As I dabble in Age of Sigmar (Warhammer) a little bit it is great to see something medieval . Great techniques and much to learn from your build.

Thank you Håkan, great to hear from you!
I have no idea what "Age of Sigmar" is, but maybe they need castles?

Massive failure to report. I need/want stronger plaster. The pieces made from Hydrocal continued to crack and break during trimming, sanding or handling, so they were angrily pushed aside. I was also "overruled" by my collaborator that those pieces were all scaled too big. GRRR.....
Starting over with a product I discovered, called "Perfect Cast". https://www.sdtoyz.com/product-page/perfect-cast-casting-material-4-lbs-bag. $9.00 USD at Hobby Lobby. The manufacturer claims it is 5x stronger than Plaster of Paris. That would be about 10,000 psi compression strength! Perhaps this will stand up to my beating.

The instructions on the back reveal the 3:1 powder/water ratio to be similar to "Hydrostone" , a very hard 10.000 psi plaster from US Gypsum.

So for a 2nd time I made one-time styrene forms that I needed. Straight sections were built on top of ceramic tile for easy removal. I thought I would push my luck even further, so I made a rectangular form, providing the outside perimeter battlement of the great hall in one piece, instead of those 4 separate pieces.
But I also repeated the 4 straight walls just in case the rectangle doesn't work..

Now poured with "Perfect Cast". Very easy mixing, the consistency of chocolate syrup, and virtually no bubbles.

Dried and removed from the forms. Very silky smooth finish. I didn't touch these for 48 hours.

I tried to drill thru these pieces, but my bits were taking forever.. This stuff really IS hard. I switched to my veteran Dremel with a fiber reinforced 1 1/2" wide cutting wheel. I ground down the crenel sections VERY SLOWLY. W rapped the bottoms of the castings with blue tape, and a couple wood stops on the board to hold in place. It worked great, no breaking, but a ton of dust, so I did it in the garage, with eye protection.

The finished tower battlement . The straight sections were easy. Much quicker than picking out waste with knives and files.

Till next time.... cutting dried clay....

Carl,
It appears you have a handle on this project now. And, my tool box has gotten much larger since I have been following your threads! In reference to Carl's Perfect Cast casting material purchase, I too have 'bit the bullet" by buying some at a nearby Jo Ann Fabric's store. A four pound bag was $9.99, but arriving at the register, I received a discount of $5.00, making the final purchase price of $4.99. I have yet to make my initial pour testing this new product. Looks like you have a winner making your new model parts Carl, and I will continue following. Nice work so far.
