- Working At The Steam Workshop - Part #11 - Fitting The Walschaerts Valve Gear ..... Progress is now being made as the valve gear is checked over and reassembled. Only one link pin was unserviceable and a new replacement was made for it in the excellent Harrison lathe at The Steam Workshop....

That steam workshop sounds and looks like a place that would be hard to go home from. So many wonderful machines and things to play with. Thank you for sharing your trips there.
Mr Appleton. I really enjoy watching your video's especially this series and the ones with live steam trains. I also like your demeanor and humor. As long as you post I'll happily watch ☺
You pronunciation of Walschaerts was spot on, well done! (Compliments by a Dutch native speaker )
Thanks you 😃
Man, this series keeps getting better and better. Thanks very much for this latest installment.
Ok got it. The nuts are basically run to the end of the threads. Thanks for the answer, and thanks for all the great videos!
Hi Keith. Enjoying this series (as ever). I noticed that the playlist does not include Part #10. I did find 2 off #23 though. Sorry if I missed a comment. Keep up the good work and many thanks.
That was as smooth as oiled silk, great to see the old girl coming along from what was quite a state, I am surprised you don't turn your skills to the full size engines as the heritage railways must be screaming out for skilled steam engineers
I was looking forward to a new part in this series.
Thank you very much :3
Great work Keith Appleton, thank you for the great videos
2 sets please Keith!! Many years ago someone sugested using socket allen screws as spanners and published what fitted what if you leave the spanners at home!!
Workshop snowed under in snow for the past few days? Removal of copper rivets from front of part built Jinty buy, abandoned in the sitting room!!!!!!!
I bought a box of various sized socket head set screws, try them on for size with different nuts/bolts, and silver solder handles to the ones that fit. More BA hardware is being made with metric hex these days too so cheap nut drivers are starting to fit.
Probably a bit too old to comment, since this video is a few years old now, but my friend has a good trick for getting oil around the cylinders. He puts the engine in reverse, put some oil down the blast pipe, and the running rolls it forward. That way it sucks oil down into the cylinders.
Very nice and useful as always. Thank you
Once again great video very interesting. Cheers Keith
Thanks for sharing
Thank you for putting the text on screen. It makes it much more understandable:)
So cool
If pins don't have threads, what holds them in place?
Is this a 5" gauge loco? Seems a bit fiddly.
Yes it was a very small 5 inch gauge loco in very bad condition ........
Really enjoyed that. I find Walschaerts valve gear very complicated but you’re excellent video has helped me understand it a bit better. I hope to build a live steam loco one day but will probably use Hackworth valve gear as it’s a lot simpler. Are there any disadvantages with Hackworth? Thanks.
The only minor advantage with Hackworth valve gear is that the timing geometry changes very slightly as the rear wheel set moves up and down in the horn slot - but really for a miniature steam locomotive, Hackworth valve gear is perfectly fine.
The guys at my club reckon it's only good in full gear, notching up doesn't work so well. This came up because I was driving the club sweet pea and thought I'd try it and it ran like a dog so I asked why.
Slip eccentrics might be even simpler than Hackworth. You won't be notching up anyway.
The very minimum of ultra violence
After making it this far, I can’t help but wonder; did you do any work or at least open the cylinders to see if there was any rust or pitting?
The cylinders are fine . . . .
Keith, there are a bunch of pins with threaded ends that you nut into place on the linkage. Do you have to worry about any of the nuts coming loose after some running? Do you have to go back and Loctite the nuts at all? Thanks!
When tightened, the nuts are a tight fit on the shoulder of the the pins which are exactly the right length . . . .
What kind of oil did you use during the assembly?
It is some that they use in the Steam Workshop - probably motor oil . . .
Now I know why everything I build wears so quickly, I always use bolts/threads as bearing surfaces :(
Even better if you use silver steel and harden the pins.
Heusinger gear not Walschaerts. Heusinger invented it first. Name was changed in English speaking countries during WWI.
You can go to google translate and have it pronounce Walschearts correctly. Good luck emulating!
Yes I know you can - Yes I did that .....
