Jason Its an RDG Casting, Quality quite good, not to much flash and running resonably true only needed a couple of mill skimming off it. It had one hard spot on the rim from a chilled flash, but that came off OK with a TC tip tool. Stew

Thanks Pete Its bin a good day in the shop finished off the fly wheel. In the independant four jaw true it up so the inside of the rim is running true, then clean up the hub and the inside of the rim, face and turn a register on the OD. Turn it round clock up the register true, and clean up...

Thanks Guys Bit more done on the engine the pillar parts was more about mass production than anything, made the roundels from 20mm brass bar, i'm going to paint the columns mat black and leave the roundels shiny brass :D Used a form tool to form the rads drill and parted off Sorry about the...

As these parts will have a delicate edge that will be easily damaged by the chuck jaws I made a split collet, to hold them. Using the split collet part the flutted collumns off to length. Then as its important that the collumns are all the same length I fitted my back stop into the spindle...

That worked well Stew

Things slowed down durring the past week while a did a little commission work ;D Started on the base, first I squared it up to size, then drilled and tapped the cylinder fixing holes for M3 studs. This was so I could set the cylinder down and get some idea of whare the cut outs were to go...

Another little trick is to drill and tap before you split, that way they bolt back together exact. Comming together well Brian it will soon be a runner. Stew

Thanks Jim you'll enjoy this next bit:----- I did ;D Eccentric strap:- I've had it in mind to make the strap silimar to an eccentric on an 1850 ish beam engine I saw in a museum, it was a lovely cast iron job with a delicate latice work of circles, this will be too small to do the cirlces but I...
