Romulus Valve Gear

On behalf of member J.W.
"I am having a problem in sorting out the valve events on my Romulus and I wonder if another builder of it had the same problem and was able to resolve it?
The engine goes, but not as well as it should and reverse is really very poor with the locomotive sometimes requiring a push to get it going. I have followed the drawings but I am not convinced that they are totally correct.I shall be grateful to have some guidance."

If he likes to give me a ring I'll certainly chat about it.

Thanks, Bob! I have passed your phone number on to John and I am sure that he will call you! He lives in Minehead so a bit of a distance from you for a face to face chat!

Long time ago since I made my Romulus and cannot find the drawings at the moment but I seem to remember an error on a rod, the valve rod I think, which meant having to raise the weighshaft by either 5/16" or ⅜".

Can have a sort in the workshop if needed.

That's is not an error that I have found (doesn't mean it isn't there though). The biggest problems I have found with numerous Rommy V/Gs that I've messed with is that people change one thing slightly, due to some other alteration they've conceived, and it has a 'knock-on' further down the system. I have to say it's not always the case, but one of the most common, is assuming that the die-slide should be vertical in mid-gear, then they move other sizes/positions around to achieve it. Hackworth is all about centres and right-angles. Whilst it has its detractors, it is generally a very forgiving and long lasting Gear.

I seem to remember that some time ago (15 / 20 years) the late Rodney Weaver doing an article for the News regarding corrections to and set-up of Romulus valve gear; I guess it will be in the News archive on this site.

I think you're right, John. Finding it would be a lot easier if we had a search facility!

I have a crude index for the news letters in which I can find 60 entries for articles and 38 entries for "Letter to the Editor" from Rodney Weaver.

I can post the results here or email to whoever would like them as appropriate.

p.s. indexing the newsletters in the archive is probably not practical as a significant number are scanned images presented as a PDF and thus much more difficult to index, not impossible, just would require conversion to text before indexing. I just used the MK I eyeball.

p.p.s. If the editor would like a copy of what I have you are welcome.

Looking up my old News Index (do you remember them?) Nos. 0 to 80 I find the following listed. I append here in no particular order or importance.

G Orton - i15 - p11
G Orton - i43 - p39
J Meacher - i43 - p40
J Meacher - i38 - p24
R Weaver - i54 - p15
R Weaver - i42 - p16
And if you don't like Hackworth try Baker - i55 - p15

I hope this helps.

There was also a piece by George Smith on setting up Hackworth VG. My original Roger Marsh drawings have some instructions on setting the gear once it is installed. By the way, my name is Meatcher, not Meacher and I was Editor of the News in the mid 1980s. Rodney was one of my stalwart contributors upon whom I could always rely if I was short of copy.

Thanks for chipping in Jack! John W has sorted out his difficulties with the help from Bob Gray - and the loco is now running well!
