Things slowed down over the last couple of days but did manage to get a little done on the cylinder end covers, these are just plain turning jobs the hard bit is dealing with the thin section when you do the second op, I deal with it by puting my back stop in the head stock and pushing the thin cover up against it this help get it concentric and keep it secure. With the piston end covers with the stuffing gland its important to get the register with the cylinder concentric with the piston rod hole I do this by clocking the cover up in my three jaw i know that if I keep trying it in diferent positions one of them will be spot on. Drilling the bolt holes and drilled to the full depth of the flutes this was enough to do three of the covers. A bit of fancy work Clocking the a cover up Covers done I'm planning on fitting a governor to the engine I drew one up but as I was unsure if I'd got the proportion correct The first pic shows the governor against the cylinder at 1 : 1 scale Its far too big This is it 1/2 size Better but a wee bit small I think I somthing slighly bigger would be about right, some of the parts will be a bit on the small size but still doable.

Nice work on the covers Stew, if you drilled the hole and turn the register at the same setting in the lathe wouldn't they be concentric anyway? The 1/2 scale governor looks just right to me :thumbup: Nick |

Yes but you'd still have to turn it round to drill and tap for the gland nut which also registeres on the piston rod you pays your money and take your chance :D Stew |

Hi Stew I do like the look of that governor :thumbup: ,nice bit of detail in the bracket :med: Rob |
| NickG:
:doh: Of course Stew sorry! On the covers for the other end I presume you must have spun them around and turned the register last as well, as you did the fancy pattern on the face you can see? Do you just turn them near to size then take smidgins off to get a good fit in the cylinders or just measure them? Cheers, Nick |
