PART 14: A New GWR Pannier

摘要

The arm for either type of lubricator can be made from an offcut of 16swg steel and the pawls for the ratchet can also be made from the same. Both pawls need case hardening as do the eyes at the end of the arm. To make the cam I used a piece of 3/8 inch BMS bar. All you need do is chuck it in the three jaw, face it and then slip a piece of 3/32 inch strip under one jaw and a piece of that 20swg strip again and that just gives enough off-set to centre for the hole and then drill No.41 for about 1/4 inch. Part off a slice 3/16 inch thick and there is your cam. Drill down No. 43 from the centre of the edge opposite the hole and tap 6BA for an Allen grub screw.
