24.3mm Axles - Help!


KH1

807 views

Help - my patience - already stretched - is now at breaking (pin!) point!

 

Into my stupidly hectic schedule (which explains lack of updates), I am trying to fit in what has turned out to be a pretty major project - to ditch the scale chopper couplings and replace with auto couplings that might actually stay coupled. I have settled on a heavily modified Dingham now but removing the old couplings is proving rather troublesome. Having removed all the bogies from the wagons I have also set about trying to weed out those that do not run smoothly enough. This has resulted in two things;

 

1) A rather large pile of bogies
2) A realisation that that the only ones which work properly have a 2mm pinpoint axle which is 24.3mm (or slightly under) in length.

 

Obvious solution is to replace all the longer axles - mostly 25.8mm with shorter ones but can I find any?

 

A Google search brings up plenty of wheels on axles but no body seems to state the axle length. Although it would be great to be able to find a supply of axles only I am now desperate enough to buy complete wheel sets and use just the axle.

 

So it would be brilliant if everyone across the land could whip out their Vernier calipers and measure their axles in the hunt for ones of 24.3mm and it would be even better if you can remember where they came from!

I did not even think you could remove the wheels from a Wrightlines bogie after it was built. I have a number of the kits where I have not built them waiting to buy new wheel sets. I will be following with interest.

The Alan Gibson option is nominally for a 24.5 mm axle, although having just measured a couple of wheelsets (admitted purchased a few years ago, before the business changed hands) they're more like 24.4 mm on the Vernier.

 

I rate these wheelsets very highly (robust, free-running, good profile), but they are ferrous so are strongly attracted to uncoupling magnets!

Thanks to everyone for help with this. Have a few Emails out now exploring the 24.5mm axles. Is interesting that Ian found them to be 24.4 which explains why my searches for 24.3 got me no where. I did also try the 'so obvious  I didn't think of it' route and tried tuning a long axle down on my lathe, but a combination of it's rather slack and worn out nature and my ineptitude meant I couldn't quite get the end pointy enough and or the correct length. If all else fails I do know a man how would be able to do it and could just end up cheaper than buying wheel sets.

Markits do Lima 2mm axles for any of their wheelsets. The 7mm NG Assn. sell the Gibson curly spoke wheels on the narrower 2mm axles. I’ve used both recently on scale width 3D printed wagons and bogies, and for scale width bogies on a Worsley Works coach kit. All are a nominal 24.5mm axle length.

I’ve just discovered a great source of wheelsets  - in Berlin! I ordered some Kleinbahn 9mm diameter 23.8mm pinpoint axles, they arrived swiftly and are excellent - and cheap, £1 approx per axle.

 

Closer to your needs are some Marklin DC 9mm dia. on 24.4mm pinpoint axles, here:

Their selection of wheelsets is superb, and they also do some axles alone, but not the length you need.
