Thanks for your interest and kind comments lads I ran the engine for about two hours yesterday whilst I gave my shed its monthly clean out and straw change part way into the run it developed a higher buzz I though that sounds like the little end bearing has gone, It was still running so I just left it to get on with it when I stopped it the little end crank pin was gone:- really gone couldn't find it any ware, I guess the nut had come lose and the pin had moved that what was causing the higher buzz then when I stopped it and moved it the pin had dropped out to be collected by the shop Gremlin :lol: :lol: :lol: :lol: :lol: :lol: This morning I made a new pin and tried it with the taco:- She just touches 4000 rpm and 40 psi and slow running 5 psi she's doing just short of 500. I found that she is sensitive to the viscosity of the oil she uses, Sticky Sideways oil gives the slowest run, then 3 in 1 oil the best is with WD 40, which is more or less what you would expect from best to worst is 2000 rpm to 4000rpm.

I've been tinkering about with it for long enough now so I decided to make a nice wooden base. So I salvaged a chip off the old thrown I don't know what sort of wood it is some sort of oak judging by the way the grain runs up and back, when we bought it, it had a label proudly saying "made in the USA" so perhaps some of you guys will know what it is. I must say, with the greatest respect, you guys know how to make a darn fine comfortable thrown :lol: :lol: It machined up very nice. And here's the final video, it runs real well but for the video it was very temperamental, after the video I put it on the bench and it ran bountifully, I think we may have some sort of gravity effect on the linkage. I'm revising the drawing at the moment so will post them for down loading in a few days Stew |

It looks remarkably like Bog Oak to me :lol: :lol: :lol:.....Sorry Stew,I'll get my coat and leave quietly :palm:. Really impressed with the engine. :bow: :bow: ......OZ. |
