Ragleth spontaneous regauging problem

I have a Ragleth that is driving me crazy. Pretty much every time I run it a grub screw will come loose and the locomotive will regauge causing a lot of issues. Basically every wheel has done it at some point, so its not just one bad apple. Does anyone have any advice on how to keep the grub screw firmly in place?

Try putting some thread lock on any bolts that take vibration,
i use the Tamiya one as a tube comes in each RC vehicle
you buy and you only use a tiny drop on each thread,
(can be bought seperate)
http://www.ebay.co.uk/itm/Brand-New...sGames_RadioControlled_JN&hash=item2ebed9e242
holds well and allows bolts, screws etc to be removed when needed.
Just unscrew each grub screw add a little TL and screw back in, its oil and
water resistant.
Don't worry about the disolves plastic bit, i have used it to glue/stick
people/cargo in many dif vehicles/trains in the past and never found a plastic
it disolves {so far} test first though just in case.

The other option i have used in the past is Hylomar its a gasket/bolt sealent
can be bought from a car spares shop, comes in dif colours red, blue, black and
gold if i remember right, you need the blue i think as the others set hard, but
check the blurb on the box for the right one, Minimans probably knows which
is the best one.

Adam, I'm prompted to ask a possibly silly question...
Have you made sure the grubscrews are entering the dimple holes in the axles?
I'm wondering, because in re-gauging they have to back off a long way to allow the wheels to move gague.
The Roundhouse system doesn't have these dimples and the grub screw just bites against the axle shaft, so it doesn't take much unscrewing to move gauge.

It ain't that silly a question because this is what I was going to ask Rob. This is unusual however and I was also going to ask if any screw has done it more than once. Either way once located in the dimples a small drop of low grab Locktite will ensure it never happens again..
 
I havent regauged mine, but id like to run it on 32 and 45 lines. I just concerned that regular regauging might be harmful in the long run?

Putting thread lock on sounds a good idea, ive been thinking on making sime gauge adjustable wagons using thread locked bolts on the axle boxes, the just hot swapping axles.
 
I find it easier to re-gauge Accucraft locos than Roundhouse locos because the dimples make it so much easier to locate the wheels properly. There shouldn't be a problem frequently re-gauging them, but make sure you use the right size Allen key so that you don't wear the hexagonal socket, and don't over-tighten the grub screws. It does sound like you haven't quite got them lining up with the dimples. If the wheel is stiff on the axle sometimes it can be a bit difficult.

Just remember to put the loctite at the axle end otherwise you wont be able to get your allen key into the grub :bigsmile:
