Glad to have finally caught up with all your restoration videos. My guess at the rpm was shy of 200 rpm so I failed. Looking forward to the next episodes as and when they come out. Good luck for the rest of the restoration. 👏👏👍😀
My dear friend Natel Taylor has a 7nhp expansion engine (Number 7497 "Faith") he has owned since 1965. I set her governors up a few years ago, but I was about 150 RPM over the top on my guess. Faiths governors are rather worn, but at 91 years old I think Natel has decided they will last him out (Natel is only 17 years younger than his engine, and both me him and the engine have birthdays all within in a few days of each other) . In regards to your pulley, If your making a new shaft, I would repair that pulley, making the missing bit a uniform shape, and braize in a replacement bit, and then clean up and shape as required. Its always much nicer to keep as many origonal bits as possible.
@@James_Rivett Interesting. I’ve never belted these up in the time we have had the engine. luckily these old girls don’t need to run the saw bench day in day out now so having a perfect set isn’t so much a worry. I never really gave fixing the original a thought, it would be nicer to keep the original. All the new bits look very out of place on this engine due to the heavily pitted original parts. I’ve got to find a good picture of a set or a drawing to make sure these go back together correctly as they weren’t right when I taken them apart. Cheers
@@VintageIronuk I actually like seeing the age on things, I know many throw things away or machine the pits out, but I like to see the age of things. Every ding, every knock, every changed bit, all tells the story of our engines. Its just a shame they cant talk, because what fascinating story's they would have to tell. If you get stuck for photos, message me, and I will go and get some of Natels. I did do one modification to his on the link pin you change from manual and governed expansion, in where the original on his had to lock nuts, I changed it to a washer, full nut and a split pin so it was easier to change (albeit he uses a R clip) whith out trying to reach across the motion with spanners (you can now do it all by hand). We had his safety valves off the other week to put some graphite on the regulator faces. The man who made the pattern for those blocks was a very clever chap! Much nicer than the likes of fowler or burrell inside!
@ Brilliant. I will likely be in touch if I can’t get it figured out. The issue I have is with the arm that takes that pin. It has a boss on the end and seems to be offset away from the little link arm. Whoever put it together last, put the arm on upside down making the point for oiling on the bottom and inaccessible. Will likely explain better in a future video. Any ways thanks for the comments and for watching. Cheers
I guessed 300 rpm, It must have turned round a few million times in it's life ! , always a struggle to dismantle old equipment. Thanks for this weeks update. Brian from South Yorkshire.
A bit of heat doesn’t halo help at times! Pity my shed is full of the tractor and other crapto have everything handy wheel I’m working on bits 🤦♂. Looking forward to the next episode 👌👍
What do the ball weights control on the steam engine. Nice piece of engineering. It always amazes me how engineering goes into making parts like this . Considering we have more technology than they did back then . 👍👍👍👍👍👍
@@markclifton14In simple terms the ball weights (when hooked up) will regulate the amount of steam entering the engine. If there is a load put on the engine when running on the governor the amount of steam inlet to the cylinder will increase to keep the engine running at a constant rpm. As the engine speeds up the balls fly out and decrease the amount of steam. Hope that makes sense.
"One blade and it's already knackerd" That sounds about right! Forging that shaft part would not be hard for a man that understands how to do it. I am not that man, however I have seen men do such things and more on a power hammer with ease. They make it look simple. Indeed it may be witchcraft or wizardry, nevertheless it's amazing. Might have been die forged as well. Cheers from the US.
Thanks It was once forged so definitely can be done again. Just amazing to see how some of this stuff was made. Would be good to go back in time and have a nose about the Wallis and steevens workshop. I’m going to have a crack at the forging Cheers
@@VintageIronuk It would indeed be fun to go back in time to see that. Instructive at the very least. I and probably nearly everyone else in the audience would love it if you filmed your attempt at forging that beauty. Good bad or ugly. Cheers
Nice work, i enjoyed watching that being stripped down, are you going to polish your balls, as they look pitted, would be interesting seeing how that is done.🙂
@@garryowen6671 Hi Garry I’ll be stripping the paint and will assess what’s underneath. Not sure they will polish up well with all the pits. Will likely just wire wheel the lot and leave them oiled. Having your balls polished does sound nice but would it help them work any better 😆 Cheers
@@VintageIronuk Na, it will not make it work any better, But you are putting a lot of work into that engine, she will be a lovely engine when finished, so you have to do something with ya balls, but saying that i have no idea if agricultural traction engine had polished or painted when new.
its geared up via the crank to governor pulleys and belt, then geared down slightly on the bevels. Crank RPM will be in the area of 150rpm (+/- a bit) (wallis used smaller flywheels than their contemporaries where other makers 8nhp would be around 120rpm)
Great work in saving these old equipment. Nice video

@@andrewdolinskiatcarpathian It’s been quite the journey to get caught up. Hopefully we can keep up making new ones. Thanks again 👍
Cheers
good video as allways

Hello from north Carolina USA
@@jamest.5001 Hello 👋
Thanks for watching
Norm
Guessed at 200 rpm Norman but couldn’t remember how big the crank shaft pulley was. No far away.
@@jameshodgson1609 Extremely close!! I’m not sure how accurate the lathe rpm counter was looking back. She started at 8rpm sat still!!!
Cheers

Ha well I guessed 200 so I’m not too embarrassed about that one.
Taking old iron apart and cleaning takes a lot of work, Is the governor running 1 to 1 with the crank? Thanks Cheers
@@RandysshopNo the flat belt pulley on the crank for running the governor is a lot larger in diameter. At a guess I would say 3-1
Cheers

Gotta be at least 200rpm
300 max ?
Not far out at all 👍
