South Devon Railway Engineering have just added these pressings to their growing list of parts for the heritage rail industry.
Whilst more used to pressing boiler backheads from red hot 10mm thick boiler plate boilersmith Peter Bowden has built all the tooling to enable these items to be pressed cold from 2mm galvanised steel using the John Shaw 700 ton vicing press which really doesn’t know there’s anything going on !
The use of the slightly thicker 2mm galvanised steel (instead of the normal 1.6mm sheet) allows for a full draw in each corner meaning no fabrication is needed and these are the finished article saving a lot of time and additional expense.
The great advantage of using a vicing press is that the press first grips the workpiece firmly, with 100 tons force, preventing the blank moving whilst the punch is powered through using separate rams. In this case Peter used just the centre ram.
The lock hole is not provided in case the lock is not in the standard location. Also the hinge notches are not present to allow for variations in the individual doors.
