I just finished Stuart's Victoria engine. The are remarkable models. How did you get such a high-shinny-polish in the iron parts such at the flywheel? Check out the video of my engine running!
Here's your answer, Bernard, from Bob Marchese... Dear Bernard: Understand that the smoother the part, the better shine you can get. After filing and grinding as far as you can go, sanding with progressively finer grits of "wet or dry" sandpaper is the next step. The final step is to go to a paint & body shop supplier and buy a bottle of diamond cut compound. I use Meguiar's 2.0. This stuff really works. I think I paid about 20 bucks for a quart bottle some years ago. If you can spin the part in a lathe, you will do OK with just a soft cloth and the compund. If not, you can use a cotton wheel on a bench grinder with the compund applied to the wheel.
Sharon Poteet Thanks for the reply on polishing. It's a great looking model! Now we just need to take care of the "knock" sound that occurs when the piston comes to the bottom of it's stoke. Most times, this is fixed with just simple valve timing adjustment. Setting the valve to slightly open just before the piston comes to the end if it's stroke will allow "early admission" to the cylinder. This in turn cushions the piston, and allows for any slack on the crank or connecting rod to be absorbed with the steam or air you are using to run the engine. Check out my Stuart Victoria videos for an example of this as the Victoria is just a horizontal set up of the beam engine. Happy steaming!
Great looking model... 2 remarks though: 1) At certain points in the video you were running the model at a speed (RPM) that was totally out of sync with actual usage of these engines... 2) You need to do something (timing probably) about that hard knocking sound!...
There is something wrong with that engine all that knocking it is working like a steam hammer!!!! I have seen other beam engines working no knocking!!!!!
Shouldn’t be knocking, otherwise beautiful build
There's someone at the door!
Knocking is caused by valve timing check out Kieth Appleton videos a master of his craft
A lot of love went into that. And it was worth it.
Nice build. I just started a D10
Nicely done! 👍
Liked the whistle on this one - can you please tell me what it is and where sourced?

Is the valve timing set for a proper lead? Lack of lead will cause knock at end of piston stroke. Is the knock absent when running on steam?
Lovely model but what is causing that tapping noise?
Sounds good, how it should 😊👍

knok, know knok. I cant listen to this
+Tech Uno that knock knock is not a good thing it ruins everything
indeed it does
for me it's the piston on the downward stroke just shave off a bit of material
timing off, valve setting ???
Beams don’t run that fast.
Beautiful engine, but it just sounds awful. The timing must be off.
The Governor is adjusted wrong. Cuts air / steam feed much too late. Spring too strong or / and balls too light. Silly high rpm ...

WHAT IS KNOCKING?
It sounds terrible but looks very nice. Needs to be run on steam, otherwise no point. Also, no lagging on the cylinder so it does not look authentic.
