Found this picture of a dake engine being used to power a winch, this got me wondering if I could use my engine to model this set up, but I'll need to drop on some gears bigest about 4 to 5 " with the reduction train to match, can any one help ?. Stew |

Hi Stew Adding the winch would be a touch. Dont think i have any gears lying about. If you get stuck i could cut a set ot plain gears, leaving you to cut the spokes out. Rob |

Thanks Rob I won't be taking this any further until I know I have a running engine, in the mean time I'll keep looking for gears, if nothing turns up I may just take you up on the offer. Thanks again Stew |

I realy wasn't looking forward to maching the recesses I'd ran through it countless times in my mind with some wierd and wonderful ideas, but wonce I'd got the parts arround me I decided to keep to the simplest method. So for the frame I just bolted the back plate to the frame, clocked it up square on the mill table. Then centred the mill on the bearing housing bore in the back plate. sorry about the crap pic. Then using the boring head bored out the recess. sorry no pic. This is it finished. For the inner piston again this was squared up on the table, and using the edge finders it was centred under the mill At this point thing got hairy. I had the boring tool sticking out of the side of the head as i thought this was a less flimsy set up but it ment I had to run the mill in referse, this worked fine for the outer frame. But I didn't realise the mill head was screwed into the morse taper mandrell, this time the bugger unscrewed. :doh: :( This gave me an involantry bowel movement, after a shower and a change of pants, :lol: things wern't as bad as they looked the part and boring head wasn't damaged. So changed to this method i was pushing the capacity if the head, but by taking small cuts it all worked out. Hopefully that the worst bit over, its getting close to the moment of truth. Stew |

Whoops! Glad it did no harm, considering the amount of work you've put into it. I see that we got the full unexpurgated version, whereas you redacted it for the ME forum. They only got your last pic, labelled "Got the recesses machined in the cylinder for the inner piston flange apparently this helps with sealing of the ports." Andy |
