Re: P4 steam loco driving wheels centre outside boss

Thanks for your replies, folks. I'm getting the message that you take the thickness of the boss as correct, and you get or make a suitable length axle. Not the inverse, taking the axle as the given, and filing or sanding down the boss to the length of that axle. Nor is anyone so far going with Dave...

Re: Drill for rivets.

The rivets have a diameter of 1.1mm and the same goes for the hole punch. A drill should be the same.

Re: Scaleforum 2019

It seems some photos, especially from iPhones, can have orientation info built in. I have found that opening it in MS Paint, rotating if needed, then, whether rotated or not, doing a 'Save as' will allow the resulting files to be uploaded and displayed correctly.

Re: Close Coupling

http://www.proto87.com/media/gresley%20sub%20coupling-600.jpg Just checking on my (Gosh) 65 year ago memories. These (prototype) coaches would have been coupled with screw couplings and the buffers would always have been in contact. Or even slightly compressed by the couplings. Is either or both co...

Re: Exactoscale wagon couplings - a problem

The thinned bit should be half way up the long side of the link, then you have to try hard to get it to fall out.
But I just open the link and thread it in, then close the link. Can't do that in full size :)

Re: Extracting coach wheels from Hornby Gresley suburbans

So 21.6 mm, that is very tight for a P4 wheelset, just about possible with an Exactoscale wheelset. AGs are 21.7 mm wide.

Re: Extracting coach wheels from Hornby Gresley suburbans

From Andy's and Knuckles' replies I would surmise that the sideframes are spaced closer together than needed for P4 and maybe not using 26mm axles, I suppose that does not affect Andy but it would be rather a shame as the recent Hornby LMS and Pullman bogies have been easy conversions. Perhaps the o...

Re: Extracting coach wheels from Hornby Gresley suburbans

I have not tried these specific bogies, but most Hornby (and Bachmann) bogies can be flexed enough to get the wheelsets in and out. A thumbnail each side between axlebox and wheel has always done it for me. If you can't get the old ones out then you won't get the new ones in. Although while the whee...

That should just be the minimum width on the drawing, a lot of manufacturers went for the maximum.

Re: Can I drive a Seep motor from a lever frame?

The simplest solution is to use a Capacitor Discharge device designed to be the interface between a simple switch, ie the microswitch on the lever frame, and a solenoid type point motor. MERG has kits for this, PD3 at approx £9, that can link 2 levers to up to 4 points, eg 2 crossovers. An alternati...

Re: Chassis kits for CSB

I said the opposite. Of course the same laws apply. There is not a separate, different case. But when calculating the effects of moving vehicle body inertia, the value of "a" in F=ma is zero when stationary and only increases gradually as the vehicle speed increases. That formula does not...

Re: Chassis kits for CSB

So you do want to rehash it :) One if the "what for" points is that making chassis construction simple, fast and impossible to get wrong, would likely steadily increase the membership of the Society tenfold. Maybe even start a trend of there gradually being easy to manufacture RTR P4 equip...

Unless you operate in the dark light dependent resistors (LDRs) work from the ambient light and fit nicely between the sleepers detecting anything passing over putting them in the shade. The MERG pocket money kits have these detectors for £0.88 each including an LED for the indication. The circuit o...

Re: Chassis kits for CSB

Obviously sufficient weight of the loco will force all the wheels down on to the flat portion of the track, by forcefully bending the wire against its alternating tendency. But that means the individual wheel weights will be increased or reduced incorrectly for optimum track holding. Andy, do you r...
