moving along, turned the cylinder covers, the front one is rather simple The rear one is a bit more complex, as it has a stand-off flange for the piston-rod gland: got carried away machining, so only a final "as done" photo Turned blanks for the valve and regulator glands Spent some time fly-cutting some brass to dimension for the valve chest and regulator chest, started machining the valve chest by doing some layout, drilling the holes for the studs tapping size to use as a template for drilling them in the block, and milled out the centre Turned the outside dimension of the gland boss, and then drilled and tapped the gland in the mill installed the gland, chucked the whole thing off-set in the 4 jaw to finish turning the boss and the gland as one, did one side, flipped it over to do the other side Spotted the tapping holes through the chest, drilled and tapped them in the mill And here it is mocked up with some bolts I had handy, studs and nuts will be fitted.... And here's where it's sitting in a little pot of alum solution to rot out the tap I broke off in the last hole.... Decided that it was time to quit for the day at this point! |

Well, the alum thing worked, so no big drama to deal with... Carried on with the regulator chest, just the steam chest all over again with minor dimension differences... set it up in the 4 jaw to turn the boss for the gland flipped it end for end to do a boss that will capture the end of the regulator rod Once the middle was milled out, used the tap-drill size holes I had drilled in it to locate the holes in the casting, spot, drill, de-burr, tap, open up the hole in the chest, install, repeat for the next hole... Worked out fine, managed to not break any taps this time... and here's the family photo.. with the flashy recess milled into the valve chest cover just for the look of it.... Cheers, Joe |
