Large size wooden models of guns.

Wooden models of guns for subsequent casting of metal. Large size, large scale, this work was interesting.

Igor! Happy New Year!!! I need two carronades in the 20-m scale. Will try to make independently but under Your strict control.

Thank you. I agree

Igor! Let me ask the first question: what tree is used for forms? My machines allow me to make any kind of work on metal and wood. Second question: axle sharpened separately from the barrels of guns? Thank you!

I used an ordinary pear. Main works made on lathe. Trunnions (axes) were inserted separately. Small parts were glued in milled grooves

О.К.!!!

Castings when rammed up and poured do not hold sharp corners, inside or outside, as do machining s. Need some transition around the trunnions, and other objects cast in place with the gun, bearing surfaces such as trunnions were machined or trued in a separate operation. Those gun patterns look well done, just not ready for sand casting as most were done.

Thank you for your comments. Guns will casting in soft silicone molds.

[aviaamator]

What brand of silicone to use for making molds?

Thank you for your comments. Guns will casting in soft silicone molds.

If you were casting a full size gun you probably would be using a green sand mold as was done originally. My post was only intended to address the cast in transition areas the original guns are required to have because of their casting methods, those fillets did add strength. Your model gun patterns would probably be more faithful to the original by including those transitions, even if your intended molding process will hold sharp corners, the guns you are modeling, did not have your casting options.

Sorry, I will not cast cannons. I got an order only for wooden models
