Re: Top up valves and anti-vacuum valves.

The top up valve over the sight glass seems to be be an additional mounted tune up part. As I know was this not ex works. That's how Regner do it. A goodall type water filler valve was included with most Cheddar Models locomotives, but was fitted into a spare boiler bushing, not on top of the sight...

Re: Roundhouse Bertie

Two things to consider when R/C'ing a Bertie. 1. It is fitted with slip eccentric valve gear so you can only radio control the regulator, and need the out of scale human hand intervention when requiring a change of direction. 2. Roundhouse use 2 different regulator controls, one for manual control &...

Re: Safety valve

The Roundhouse safety valve uses an internal 'O' ring as its seal and likely will need replacing over time (I've replaced several Roundhouse & Accucraft internal safety valve 'O' rings in the last couple of years). http://www.roundhouse-eng.com/tech.htm#sv These internal 'O' rings are not includ...

Re: New Mamod offerings

Mamod are a member of the Unofficial Mamod Forums. I understand that it is more than just coincidence that their diesel, Boulton, has similarities to the LC Models Danny, which is no longer sold by Kent Garden Railways. It has a 12V MFA motor & bevel gears. http://modelsteam.myfreeforum.org/ftop...

So if we can't use that what do you recommend? The right water to use is a controversial subject online.

Re: water level glass

it works out at about eleven pence per boiler full! And £35 for a replacement boiler. De-ionized water - this is often sold for use in steam irons and the general opinion amongst the small scale live steam community is that it should not be used. Because of the way it is 'purified', it can cause lo...

Re: Regner whistle fitting

My whistle kit is some years old so I see they have now added Lötringe (solder unions/nipples) to the kit as well.

Regner state that these should be silver soldered to the steam pipe.

Re: Regner whistle fitting

Re: Silk purse out of a pig's ear?

Depends if you are a tinkerer or not. At a recent running day a fellow member was relating a story from another tinkering member. He bought a new Roundhouse loco. Got it out of the box & gave it a run, which of course was faultless. Back into the box, and a repeat on the next run. After it did t...

Re: water level glass

In my experience the problem with sealing these sight glass's is down to two problems. 1. They were originally sealed using an oval shaped seal. At some point in the Mamod ownership takeovers this seal was changed to a thin 'O' ring, and this is what is still supplied now by MSS. My solution here is...

Re: Mamod upgrade

I hate to be distrustful of domeless engines Effectively these aftermarket Mamod/MSS replacement copper boilers do have a steam dome, it is just part of the steam turret at the rear. After all, this is what Accucraft & Roundhouse use on most of their locomotives. The only boilers I've suspected...

Re: Mamod Brunel "cabside" length

My Brunel is a Mark I Version II. Do not think the cab sides have changed on the Mark III but you never know with Mamod's constant improvement policy.

There is about 0.2mm difference between each end.

Re: How to replace wheelsets?

Sounds like MSS quality control has not changed then. The problems I've heard of with MSS wheels is either they are wide to gauge (back to back greater than 28.5mm) or their flanges are too thick so that even with the correct back to back they still end up wide to gauge (greater than 32mm across the...
