Part 34: The Expansion Link Trunnions
HTML-код
- Опубликовано: 6 сен 2024
- Welcome to Part 34 of my long term series of videos covering the build of Don Young's Hunslet 0-6-0 Saddle Tank Locomotive in 5" Gauge.
In this video I make the Expansion Link Trunnions, another exercise in working with small parts.
Given the nature of these sorts of projects, new videos will be posted as I progress through the build but there will be no regular cadence, rather their frequency will be dependent upon time available and of course real progress on my part.
If you like what you see, please do give me a thumbs up and subscribe.
Enjoy!
my goodness, it's only when you hold them with your fingers you can appreciate how small those parts are! Bravo Sir. All the best, Matt.
It's great for us that you are now uploading new videos more frequently. Thanks!
I understand why you make the CAD drawings so you get the metric measurements you need. Ive started drawing up parts in CAD too because too often the dimensions needed at an interim stage are not on the drawing. Also with complicated parts it proves (or otherwise) that the original dimensions work.
I continue enjoying your project - thank you and keep it up 👍
Very nicely done indeed - the wicking of that silver solder was something to behold. May I ask about your button filing? I used regular mild steel and decided not to harden them - but they were free to rotate on their pins, so essentially lifted the file off the work with their motion, rather than acting as stops. Is this two distinct methods? Or did I do something wrong?
Hi William,
Thankyou for the feedback.
The buttons are Silver Steel and hardened by heating to Cherry Red and then dowsing in cold water.
I did show the process in an earlier video, but used Mild Steel, which doesn't harden 😁
Cheers
Mark
@@markshomeengineering5243 Thank you! Why silver steel over tool steel? Or are they the same thing just American/English demarcations?
@@williamsworkshopuk I think they're the same thing.....
