Hello, The screw thread size is 10BA on the front and rear pairs of drivers. The Center drivers have a crank pin pressed into the wheels with a smaller thread size for the screw that holds the parts there. The center crank pin size means the GW quartering tool is not suitable. I have now got a Bill Bedford quartering etch to put together and try. The 10BA screws for the front and rear pairs will need some sleeve to match the center crankpin diameters so the pins match all pairs. trustytrev.

Hello, I have come to the conclusion my choice of a piercing saw with a 150mm deep throat to start with was asking for disappointment due to being more difficult to handle. I am waiting for another with a shallower 70mm throat which should make things easier.I have also ordered some heavier blades now the size options have become more clear to understand. I had tack soldered the Comet chassis sides together to enable cutting and filing of mirror images. I am trying my best to make use of as many of the original parts such as wheels and motion from Hornby's rebuilt Scot as it would be a shame to discard them. Quartering the drivers with different sized crank pin fasteners is in the process of being resolved. I discovered the GW quartering press was a problem if going this route. I am awaiting the arrival of another type that rests the axle on two center flanges and requires the crank pins to just touch either side to right angled verticals. trustytrev.

Hello, Are these 2mm scale? trustytrev.?)

Hello, I have now seen the light. I presume the impending newly tooled Hornby models are the reason. trustytrev.

Hello, I believe bigger and finer is better but how big and how fine is the question probably. trustytrev.

Hello, Correction needed. I should have said a piercing saw. I have that many saws nowadays it can get a bit confusing I bought a piercing saw on ebay and a pack of assorted blades. I have no idea if the blades are actually suitable for what I am attempting to do. I thought a selection would cover my bases till I became capable in this skill. trustytrev,

Hello, I have had a go at using a fret saw on a Comet chassis. It has not gone very well. I have watched people doing such things online to try and copy the techniques shown. So what size blade are you using Tony when you make it look so casual please? Thank you. trustytrev.

Hello, Thank you for the mention Tony.Yes it is Trevor. I was joking about the tennis but the images in the following posts are brilliant. Thanks for showing them and the prototypical information. trustytrev.

Hello, Are you being facetious or is there really something I am unaware of? trustytrev.

Hello, Who is that fellow by the signal box playing tennis with. It does not seem a very safe environment for such behavior. As for spelling. No matter how many times it happens I always have a problem spelling feild as field until I actually see it written. How weird is that after more than six decades? trustytrev,

Hello, Found this by chance today. A real gem from the past.https://www.youtube.com/watch?v=FeojYgl5GFE Possibly a better location for this? trustytrev..

Hello, Thank you Ray. Your reply does offer an answer to the question I actually asked. I do recollect seeing a reference to them possibly being BA somewhere now your suggestion triggered some thing previously forgotten.Now the question to myself is where did I put those BA threaded bits ? trustytrev.

Hello, I encountered this in the Modelling Questions, Help and TipsWhen I asked a question about the latest Hornby Scot/Patriot crank-pin thread size. I know they are both rebuilt three cylinder locomotives in real life. I also know how to divide 360 by 3. But that doesn't tell me what I wanted to know. trustytrev.

Hello, Is this resize any use?

Hello, They are a solid brass material rollers on stainless steel pins. Self lubricating to a degree. trustytrev.

Hello, Graphite acts as a lubricant so will probably cause traction issues. trustytrev.

Hello, I am asking about screws for an electric motored 4mm model so 3 cylinder prototypical crank dimensions are irrelevant. trusytrev..

Hello, Just got one of these https://www.ebay.co.uk/itm/HO-Scale-1-87-E-Z-Riders-Standard-Track-Roller-Test-Stand-with-6-Trolleys-HP1387/372435163228?hash=item56b6dd985c:g:u80AAOSwp-5bmgaf:rk:1:pf:0 Seems to work well. trustytrev..

Hello, Does anyone know what thread size the screws for the coupling rods and crank pins are for the latest Hornby Scot and Patriot models please? I need to find something that will screw in so I can quarter the wheels with the GW quartering tool. trustytrev,

Hello, I erred on the side of caution and just re-attached the loose wire with the soldering iron. My curiosity is not sufficient to risk disaster just to find out at the moment. The thought of getting a cardboard box big enough to work inside of is quite amusing.How would one go about providing sufficient light inside to see? trustytrev.

Hello, Does anyone know if the brushes in this model are removable? I hesitate as mine appear to have wires soldered on the center of the brass bit rather then the tags below. Any assistance would be appreciated please. Thank you. trustytrev:)

Hello, A cheap dashcam off ebay would be a viable option.Runs off 5 volts and records to an sd card. trustytrev.

Hello, DCC in locomotive tenders appears to be getting more common instead of trying to cram them into the locomotive itself. An improvement I think. Did a younger person come up with that idea? trustytrev.

Hello, I have maybe misrepresented "yoof" in my remark. The person asking the question was in her mid twenties at the time(last year). trustytrev.

Hello, I think an interest in history is sadly lacking in today's "yoof" which automatically lessens any likely enthusiasm in railways. A young person once asked SWMBO at work "What is a monarch?" A sad reflection on education today. trustytrev.
