Jowitt Major Completion

Runs lovely,  I luv the chugging sound, that makes it for me! (Aside from the great work, the governor, and all the other bits!  Looking forward to seeing the next phase 

The governor does move nice and freely and unlike a lot does not sem to suffer from belt slip. I don't have excessive stretch on the belt as that all add drag but I did cut the vee in the pulley at 60deg rather than Stuarts 90deg which should help with grip. The jockey wheels probably help a bit too by giving a decent amount of wrap around and reducing the side rubbing that you get when the belt meets the pulley at an angle.

I think I could possibly have gone a fraction shorter on the link rod but at the speeds and pressures I run at there is too much blow buy due to the open ended butterfly slot to reduce the flow enough to hold it at tickover speeds.  It will speed up if I manually open teh governor so does have some effect but I'm not going to be running it at the speeds where the balls are all out.

Plus with no load to vary you don't need a governor to hold the engine at one speed, they are just for show. Possibly a No9 would be different a sthat is a faster running engine and likely to do work where a sthe beam, victoria, JC, Real, etc are all slow running engines to look at.

Paint should be dry for the next phase this evening, stay tooned

As the other two had been painted in Ford Highland Green there was only one option for this engine.







Continuing the minimal bling theme, I went with satin black for the governor brackets rather than polishing up the gunmetal




I did splash out on a bit of red for the cylinder cover, would have been nicer if this were an iron casting for looks. The letters had a skim cut taken off their tops after painting to bring out the bare metal, left at that no polishing.

Don't tell Jo as she may drop a stitch but the four nuts holding the exhaust chamber cover in place are not one but TWO sizes smaller. Sometimes you just have to do these things as nobody wants their nuts hanging over an edge I milled up a bit of 8BA size hex from some round bar and tapped it 6BA.




That completes the Trilogy




Finally a video of the engine running; the trio are also shown running together at the end.

Very nice indeed, I like the colour with the splash of red; they look a great trio together - shame they have to be broken up if the big'un has to be sent on its way 

You really can't tell from the fine finish, the starting condition and how much work has gone into to get it to the end point, but that's the objective of the mission ...............  

From looking at the big model you would never know how many problems you had to fix.  An old guy once told me, "The difference between a pro and a beginner is how good they are at fixing/hiding their mistakes."  I guess in this case it was fixing someone else's mistakes, but the point still holds.  Great job!

I like institutional green.  It's very calming.

Highly attractive group of engines, an unusual sight to see three similar models so considerably differing in only their size.  The paint scheme suits all of them well, some of these less traditional engine colours give a pleasantly "clean" and quite modern effect in conjunction with the brightwork of the smaller machined components. The restoration of this model has been very worthwhile.

Those look fantastic Jason and I love the wheezing sound. 

(Need to find time to read about the build as I've no idea how they work).
