What was your source of the D1-5 dimensions? Since I am doing this for an FHA-40C my PCD is 112MM right under the CAMS. In this case I think I will be using a thicker bottom plate and counter sinking some Flat Head M10 bolts. How much material would you recommend between the head of the bolt and the Mounting plate, I am a computer engineer not a mechanical engineer. I am planning to use the center piece that I am carving out of the 11" dia x 3" thick grey cast Iron round, that I am using to make the housing for my actuator. This should leave me about a 160mm x 76.2mm of stock to make the two piece nose.
Any comments or suggestions would be appreciated.
