Hi all,
Here is the start of the next plane part project, the small clamping part for the early RECORD plough plane models 043. 044 and MARPLES variant M4. Also the RAPIER models although these are slightly different.
Originals are in cast iron and are about the first part to disappear into the ether when finding the plane second hand.
Have started to mill the profile as shown here but can only accommodate a small length in my vice, work holding is pretty tricky also allowing only very small cuts. Material is some steel from the scrap bin, cuts OK.

The idea is to get this profile done as in the original as far as I can, then get the top profile water jetted from above. The small scallops and final finishing to be done by hand.

Again I think I will need some horizontal milling done to machine economical viable lengths.
Should keep me out of trouble for a while ! ![smiley smiley](data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==)
