I've posted this before, but it was lost. A fellow member pm'ed me and asked if I still have the cutting dimension sheet, so here you go :)
Sometimes folks come here and ask for plans for ewheel frames. I made a “universal” model from ¼” PDF the other day. Laid it out on my basement floor and did some measuring and wrote the numbers for different frame sizes. I decided to not make the “corner pieces” and lower horizontal arm shorter than 8.5”, no matter which frame size. No scientific reason for that. Just the way I want a frame to look like. All frame dimensions are based upon having a 8” upper and 3” lowers. 4” square tubing for upper adjuster housing. Lower tool arms measurements do not include mounting plate thickness!! This means that if you want to be able to change lower tool arm, you’ll have to take that into consideration!

How to read the numbers: “Throat” means horizontal distance from inside back bone (“C”) to center of anvils contact point. “A” is the inside length of the upper horizontal tool arm (the one the adjuster mounts to.) ”B” is inside length of upper “corner tubing”. “C” is the vertical back bone of the frame. “D” is the lower “corner tubing”. “E” is inside length of lower horizontal arm. Lower toolarm is inclined to a 45* angle measured on the inside of the toolarm! The “platform” that holds the lower yoke in position is 3” x 3” on all frames mentioned! “Fi” is the inside length of the lower toolarm and “Fo” is the outside length.
Hope this will be of use for future e-wheel builds!!
