Don Case Posted March 2, 2021 #1 Posted March 2, 2021 On frames with a chocked joint, how long is the chock? From the examples I've seen they look like about 1"(or 4 feet in 1:48) Am I close?

Jaager Posted March 2, 2021 #2 Posted March 2, 2021 I would develop a ratio and proportion using the example. What is the depth of the chock in proportion to the total moulded dimension. Looks to be about 1/2 to me, but I have never measured it. The angle of the wedge would be constant. The depth of the flat part of the ends would be constant ( no need for it to vary with larger chocks - verify this supposition), This would have the length be the variable.

allanyed Posted March 2, 2021 #3 Posted March 2, 2021 Don, there is a LOT to the sizes and shapes of the chocks. The futtocks have different sided dimensions as you move up from floor to second futtock, first futtock to third futtock, &c. The chocks likewise have to be shaped to match these sided dimensions. There is also the bevel of the frame so the cut into the futtocks and the sides of the chocks that are glued to the futtocks need to match this angle as well. As to the length, I THINK this varied at different times. Hopefully the drawings at NMM will give you a good idea of the ratio of the sizes of each portion of the chock to the moulded dimension of the frame. One example is at https://collections.rmg.co.uk/collections/objects/80749.html For a VERY detailed explanation on how to properly make these (and alternative solutions on later pages), David Antscherl's Volume I of The Fully Framed Model pages 83-88 is a fantastic source.

Don Case Posted March 2, 2021 Author #4 Posted March 2, 2021 (edited) Thank you for that link Alan. I took a shot of it, enlarged a chock and now I can do some proportional measuring and come up with a plan. Edit- That was easy. Using the molded dimension (MD) below the chock the length of the chock is 4MD. The depth is 3/4MD and the bits on the ends are 1/5MD. These are rounded out a bit. Actually I think if I had used the upper end of the chock as the MD the numbers would have been closer but on a 1:48 we're talking a few thou.
