Re: JJNewitt's Wonderful World of Wagons - Wagon axlebox and spring castings progress

Hi Russ,

It's soldered in place. The final fold at the top is made after it's been fitted to give you something to hold whilst wielding the iron.

Re: JJNewitt's Wonderful World of Wagons - Brass castings, Tubes and Bogie Bolsters

The wagon axlebox and springs saga is finally drawing to a conclusion. The production brass castings have been returned to me and I've just spent the best part of two days tidiying them up ready to be sent off to make the whitemetal moulds. Very nice they look to!

Re: JJNewitt's Wonderful World of Wagons - 3D Printed BR Era Axleboxes and Springs

A complete redesign of the Rumney Models website has taken up a fair amount of my time recently but there has been some progress on projects, most of which will end up on the whizzy new web portal. A second round of wagon axlebox and springs test prints were recieved at the Scalefour Society's AGM r...

Re: rectifying bowing plastic wagon sides

I generally find that when a plastic wagon bows it is down to the fit of the parts. Small bows and streses that are introduced during assemebly aren't necessarily noticeable at first but gradually work their way through the body. The main culprit for this I've found is the floor which seems to rarel...

Re: Wagon Corner

That's coming along nicely Jeremy! Loos great.

The sides shouldn't need supporting at the top. They are quite robust and there's also a lip all the way around the resin roof which will prevent the brass sides from moving inwards. It should be a very strong structure once the roof is glued in.

Re: Wagon Corner

I wouldn't recommend it. There isn't really that much brass in each side/end. The layers are only 0.010" thick and have a large amount of half etched detail on them. If you took a flame to them you'd almost certaily end up with a buckled, distorted mess. I wouldn't even like to tin the backs of...

Re: JJNewitt's Wonderful World of Wagons - 3D Printed BR Era Axleboxes and Springs

Perhaps it's just me, but I've never really got on with them. Of course I could be the one fitting them incorrectly...

Re: JJNewitt's Wonderful World of Wagons - 3D Printed BR Era Axleboxes and Springs

The springing is intriguing, I could be tempted to have a play even. Lord knows how many coil springs have bitten the dust at The Works, I gave up in the end and went back to solid buffers. I don't blame you. Given the spring rates of many of the coil springs solid isn't far behind in terms of perf...

That looks very nice John. The securing chains must have taken a while! They found an interesting position to put the number plate.

Has the LMS wooden ended open with steel channel seen any paint yet? I'm really looking forward to seeing it finished.

Re: Coach wheel sizes

I'm pretty sure Branchlines do 14mm coach wheels.

I've used Exactoscale wheels (14.4mm diameter) and Gibson (14.5mm diameter) under Mk1s before and you'd be hard pressed to notice they were oversize.

Can anyone suggest why the axlebox shouldn't be attached to the spring rather than the W iron? No reason what so ever why the axlebox can't be attached to the spring carrier and move like the prototype.
