Wheel loose on a Lady Anne

Hi All,

I noticed that my Lady Anne keeps going out of gauge. When I tried to tighten the allan screw i found one of the front wheels was impossible to tighten they just turned indefinately. Now normally I would blame myself for overtightening or stripping it somehow (and probably do on this one too) but oddly both screws on the same wheel are the same.

I assume I need a new collar but that means taking the motion off which seems scary!

As I run 45mm I have been able to put temporary collar between the wheels holding them to the frame which is an interim fix - but not elegant and of course there is no drive coming from that wheel either as the axle is slightly greasy and so the wheel almost freewheels.

Possible home fix? Can I send it to Doncaster?

Help please, I love my Lady Anne!

Is there not a "flat" on the axle for the grub screw to locate on? - Its been that many years since I built mine I can't remember!

I'll see if I can dig out the instructions from Roundhouse
 
Just dug out the instructions

Here's what they say

"The driving wheels are moveable on their axles and are locked in place by a small screw. They should be adjusted so that the gauge supplied will just slip between their faces. Ensure that the wheels are evenly spaced relative to each side frame. Do not tighten the grub-screws. Note that the wheel gauge can be used for either 32mm g (SM32) or 45mm gauge ('G' scale) depending on which end is used."

And that's about it......

I'd be tempted to file a small flat on the axle where the grub screw has made a mark - Give it something to locate on. I'd also write to Roundhouse and see if you can get some new grub screws - just in case the thread has gone " a bit knackered" (technical term) :bigsmile:

Do Roundhouse do repairs? Sounds like mr ham fists has overtightened them...

Don't blame yourself Mr C. Correctly engineered collars and grub screws need an awful lot of force to cause any damage (this written by an ex IBM typewriter engineer - and an 'IBM Selectric 82' had thousands of the b+ggers!). They would have come free very soon after you over-tightened them. I'd suggest you get it back to Roundhouse and see what they say.
 
Roundhouse are renowned for their after sales service - not sure about repairs though.....

I have been to the factory when I was building my Lady Anne as I had a problem with the loco (engine had been running fine in test, then wouldn't run in reverse - I couldn't work out why....... Rang Roundhouse up and asked if I could go across - They said if the fault was of my making it was chargeable - If the fault was in their product - the fix would be free - Can't say fairer than that.........

Took the loco to them - and on investigation a crank pin had come loose - Their fault they said as the wheels come supplied with crank pins fitted by Roundhouse (interference fit, plus Loctite, plus peened over on the back) - In theory should have never come loose.

So they repaired the wheel by fitting a new one and ran it for an hour or so on compressed air whilst I had a personalised tour of the factory :bigsmile:


Give 'em a ring - Nothing to lose :smile:

While Accucraft locos have "dimples" on the axles, Roundhouse don't, their axles are plain.
The grub screw threads could be stripped, but more likely the wheel threads have worn.
Replacement wheels are available, but if you're unsure about the job, it may be wise to call on Sir Haydn.
 
Oh yeh sorry -doh!

Right so I can send it to you? Or bring it round where are you based?

Maybe you could PM your number or a link to your site...
