Re: Advice please....new member

You can fit functional chairs to ply and rivet Martin, its been done on Slattocks in the last couple of weeks though it does need accurate positioning of rivets in the first place to avoid grinding and then a bit of work carving out the back of the chair. I've used pins instead of rivets to get some...

Craig and Russ, Suggest you read the original request for help, I suspect you are getting a bit more esoteric than needed for a beginner, we want to encourage people to learn by doing. Sorry, had no idea the thread I was responding in was related to a completely separate one! I would suggest though...

Re: Starting in P4- Advice please....new member

Hi Phil, The way to deal with baseboard joints, which I concur do need to be durable, is to use the cast brass chairs from the P4 Track Co (see link here - http://www.exactoscale.co.uk/4mmtrack.html). I solder these to a copper clad sleeper and make sure that the "gapping" of the copper c...

Re: Progress with Slattocks Junction

. where possible we are now adopting Dick's method of ballasting as the track is laid Presumably you're laying the track into a bed of glue? I ask because the depth of ballast you've achieved with the full depth sleepers is very good, usually what I would expect to see with thin plastic or ply slee...

Re: Wiring capacity

I'd suggest you look into DCC track bus wiring on the web. For the Manchester layout the droppers i've done so far on the rebuild are 16/0.2 onto a 13amp mains solid copper bus running parallel to the track under the boards. Its a double track with a separate pair of bus bars for each to allow separ...

Re: Brass etching

You'd probably be best talking to Brian Hanson at Shawplan, he has pushed the boundaries for his etched grills in 4mm and some of the number plate borders in 2mm. I've been using lines of .125mm thickness in .25mm (10 thou) brass a lot and I think I went thinner than that but would have to check the...

Re: Electromagnets for AJ couplings

If you go with the MSE magnets put them in the ballast between sleepers rather than under the board or something as you wont be close enough otherwise. Suitable transformer is the Maplins VN10L at 1200mA running at 9V. This combination has been used successfully by me with hinged and flexing variant...

Re: Kean Maygib 3'7" coach wheels

This is not a field in which I can profess any expertise, but it ran through my mind that there must be nearly a half inch difference between the diameter measured at the flange root, and the diameter at the front face of the wheel. I think the quoted diameter is the former(?), so which can you mea...

Re: Kean Maygib 3'7" coach wheels

Well, blow me down with a feather, Craig is right. Looking at Keith Parkin's MkI coach book, it states, in the context of saving weight compared with pre-nationalistion designs: "Some of the weight penalty was recouped by reducing the wheelbase by 6" to 8'6" and the wheel diameter by...

Re: Kean Maygib 3'7" coach wheels

Don't forget that these wheels are too big for mk1 coaches and similar, I wish they went for an accurate smaller size as they have a better shape than Branchlines wheels. MkIs don't have 3'7" wheels???? No, they have 3' 6 (14mm) whereas Maygib steel wheels are all about ~14.50mm which makes th...

Re: Kean Maygib 3'7" coach wheels

But they haven't quite got that "edge" in being accurately round and concentric that the Branchlines ones do. Only one in 100 of the axles I have had a moulding error, the rest were perfectly turned and fitted to their axles. I don't use plastic centred wheels apart from Exactoscale as th...

Re: Question on wagon springs

9-leaf springs were an alternative to 5 on these sorts of wagons, note the lack of bump stops with this type of spring too. I think Chris Croft talks about it in part 1 or 2 of his wagon articles in the early MRJs. Not sure if its a different metal quality in them or they are narrower than normal or...

For DCC users its worth noting that Auto Shuttle functionality is built into Lenz Silver and Gold decoders under the 'ABC/asymmetric DCC' feature, You just put 4 1A diodes (3 one way, one the other) at each end of the track. For initial testing of kit builds though I stick to the DC controller and B...

I haven't managed to buy some blackening for Exactoscale stainless steel wheels yet though as brass black didn't work on th...
