Hi all
Am just on the point of completing my S10V; started out as what was a 'beginners engine, easy to build' ... so I thought...

but have had a few mishaps & cock ups along the way, mainly to do with measurements, sausage fingers, aging eyesight... yeh ! I know, excuses, excuses,

, anyway got it together this weekend hooked it up to my compressor with fingers x'd, & wow away it went. So far so good, so I thought will it turn over on low pressure

, I hooked it up to a small sprayer compressor, on full pressure ... off it went

. Looking at the pressure gauge ( 30 psi ) I then turned it down to 15 psi & it was still going... down to 8 psi... still going, finally got it down to 6 psi... just ticking over...

looking good. There are a couple of tweaks to do mainly to do with valve chest jointing & valve rod mods but hey it works. One mod I did was to replace the cast valve chest cover with a Perspex cover to allow sight of the valve in operation for anyone interested enough to ask how it works, Hmmm! maybe fit a Perspex cylinder top cover later to show the piston working

So I shall attempt to place video in this post for your delectation, failing that a link to my You tube channel...

Comments / advice / suggestions welcome
