Re: Bill Bedford Coach Bogies

Secondly, one or two of the spring carriers appear to be a bit loose on the springing wire. Is there any reason that, having ascertained that the wires are of the correct diameter, I should not solder the carrier onto the wire? And similarly, becasue the wire on one side keeps trying to escape from...

Re: Another newcomer's question re wagon suspension

Waisted bearings also vary in depth, between manufacturers and between batches from the same manufacturer. Traditionally, Gibson bearings tend to be shallower and Markits/Romford bearings deeper. The BB axleguards sold through Eileens need the shallow bearings and those in the Mousa kits generally n...

Re: terrier advice

I suggest waiting to see the new Rails model, or reviews of it, before choosing. There is some pre-release discussion of it on RMWeb. The Rails terriers missed the Christmas boats from China and are now expected in the new year.

My grateful thanks for the replies. I am intending to backdate my example by applying some large "SR" transfers and removing the small 'SR' letters. It may be a case of painting them out. The other problem will be couplings. The model includes moulded on scale(?) hooks, but I do not know ...

Re: Rails of Sheffield/Dapol ex-SECR box van 45374

Concerning the SECR No.2 axleboxes: these were a Maunsell-era design of oil-lubricated box and were widely applied to SECR wagons with 3'1" wheels. The No.1 axlebox was from the same period and was used on wagons with 3'6" wheels, but precious few of those were made in Mr. Maunsell's time....

Re: Rails of Sheffield/Dapol ex-SECR box van 45374

If replacing the axleguards in this model you'll need to salvage the SECR No.2 axleboxes as, so far as I know, nobody makes separate castings or prints for these. The model comes with AGW wheels in OO. I suggest just swapping the wheels for P4 and seeing if it runs adequately with fixed suspension. ...

Re: Brassmasters Blk5 45232

Two things I've learned for tracking escaped parts: always double the search radius from your first guess, and use a UV torch. Small things bounce much further than people expect and shiny NS sometimes shows up brighter in short-wavelength light.

Re: Glenmutchkin - Turntable Troubles Reprise

Work out the circumference of your turntable and base the speed of rotation on the walking pace of the man pushing the turntable? Yes. I suspect that tangental speed was even slower than that, but walking pace is an upper limit for a model; anything faster looks wrong. I've seen films of full-size,...

Re: Exactoscale wheels and axles.

Amongst the Loctite retainers, it looks like 603 is better than 601 anyway. Advantages: - 50% bigger maximum bond-gap; - lower viscosity, making it easier to distribute in Exactoscale wheels; - high oil tolerance; - bonds imperfectly-cleaned surfaces; - good at bonding non-smooth surfaces.

Re: Exactoscale wheels and axles.

One advantage of the proper retainers is that they expand on hardening, centring the wheel on the axle.

Re: Better Running

You could also try and assess the smoothness of ride from the vibration spectrum. You'd need to know, or discover, the signature of a lurch in the frequency spectrum, and you'd need an on-board accelerometer to obtain the spectrum. Small accelerometers with wireless connection are available. I sugge...

Re: Electric traverser

Interesting. I need a wagon traverser for my eventual layout, and I'm wondering whether that above-ground kind would be better than the kind that moves in a pit. The sprung flaps at the entry and exit points might be a bit hard in 4mm scale. I can't see why Curzon Street would need a powered travers...

It looks very interesting. The combination of three different electrifications is attractive. How high is your staith above the river? IIRC, the RL Harton High Staithes were quite high up, certainly too high for a bank down to dock level. The latter - which I like, BTW - is more like Harton Low Stai...

Previously I have made the wheels a tight fit in the tyre with a bit of glue so they stay put. I have used Gibson tyres in the past but if I can get tyres CNC machined the I would design the tyre so that the centre has a more positive location. The fit I can get on an axle is similar to that of a G...
