You mean I should just keep all the ones I get and not sell any??????

Is it POSSIBLE to make money in TT? !!!!

...all tongue in cheek.

I'm already in discussion with TiTan TT on how to get a re-stock order across the pond.
This will solve the immediate issue with the trucks... but not the wheelsets.

As we discussed at OSW, I plugged my last set of Fox Valley wheels into one of the truck sets and it's loose but acceptable. Seems to roll okay with forefinger pressure on it. We really need to build our trucksets (axles & truckframes) to NMRA standards just for interoperability in the future. Just sayin'.

Yeah problem with that ^^^ is, FV wheels aren't always available. The stuff from Germany on the other hand...

Perhaps tiny "plugs" can be used in the journals?

>> C'mon man, get with the program and make some money ;) << how does the line from that old song go - " to dream the impossible dream " :lol: :lol:
Even if I did make a " profit " there's never any money in the bank because I keep spending it all on research books & material. :thinking: :geek:

So, OK another lot has been packed and is already on it's way.

Wheels - The trucks were designed to take the Mueller / German wheels simply because they are ALWAYS available and come in both standard European flange and RP-25 profile.
Fox Valley - I bought a 100 pack from him when the last lot was available only to find out they are too short in the axle. The will fit but, there's too much movement for my liking. I asked FV about doing a longer 18.83mm axle but, never received any response.

One point too note;- It turns out that the truck mounting pins are a fraction too long. They need to be shortened by 0.020 to 0.030" ( 0.50 to 0.75 mm ). I've finally tested the trucks under some of the hoppers and they wobble like crazy. Shortening the pins solved the problem. Thankfully, this should be an easy fix on the tooling block before the next production run.

Moving on - I've received & accepted the quote for the next two truck types - Arch Bar and a 70 ton roller bearing. After all the problems with the first lot, the block design for these has been completely re-worked so, hopefully, these should be much quicker than the 12 months for first lot took.

So, stay tuned to radio Richard for updates on delivery.

Mis-quoting the old saying:
The only way to make a small fortune in TT-scale models... is to start with a LARGE one!

Yup just like those. Peho in Germany makes them in brass. Oh and the 70 tons - I'll take a bunch thanks :)

Bearings - yeah, I haven't tried that yet but, they would need to be ultra small. Somewhere ?? in the shed I have some from the 2mm society in the UK that were " shoulderless " and could be pushed to the base of the axle hole. The bottom line is that they would only need to fill the hole by 0.005" on each side of the truck. The ones sold by 3SMR in the UK are too big. Both the 3SMR & PEHO are 2.0mm O/D. I will experiment over the next couple of weeks and see what I can work out for the FV wheels.
