The Unofficial Mamod and Other Steam Forum

tmuir

A while ago I bought this SL2 loco of ebay for 49 pounds.

On getting it home and giving it a clean I ended up with this.

After a large wad of cash was spent and some effort put in I ended up with this lovley SL2.

I have an article here showing how I did it.
http://modelsteam.myfreeforum.org/about1251.html

After many successful runnings it's developped a couple of minor steam leaks and performance has dropped off so I decided it was time for a strip down, clean and rebuild.

A little while ago I was given a Mike Chaney regulator for the loco by MM which fits in the cab a bit like this.

This regulator gives much greater control than the Mamod standard one.
To fit this regulator I have to reroute all the pipework to the back cab and I figure whilst I'm doing this I might aswell replace the IP Engineering lubricator

With a Roundhouse inline lubricator that will also fit in the cab and is much more efficient at lubricating.

.

I've just ordered a Roundhouse lubricator for 10 pounds from Roundhouse and tomorrow will order all the new 1/8 pipe and union nuts I need to carry out the work from an Australian company.

Once I've got the gear I need to desolder the pipe from inside the steam dome and pull it out from under the boiler.

I will then need to fit a new pipe into the boiler bring it into the cab and fit a union nut and nipple and connect it to the regulator.
From the other side of the regulator the lubricator will hook up and then after the regulator a new steam pipe will head back up under the boiler getting superheated by all three wicks not just one as happens now before connecting back into the Mamod regulator block.

As I get the parts I will put photos up here of my progress.

It shouldn't be too diffucult to do Tony! The extra superheating will prevent priming too!

That lubricator looks like it will hold a hell of a lot of oil!

Its a shame no one on here has the PPS steam block which has been machined! Always wondered what thats like!

Looks good Tony looking forward to more info.
I have an IP regulator which goes where the whistle is so will be doing some mod works as well soon. when the mss turns up it will be striped down and the regulator added.
cheers G-J

Nice work Tony. I can see R/C would be real handy on these locos

Interesting stuff Tony. I'm looking forward to seeing how it goes.

I ordered the rest of the parts I needed today so hopefully on Friday or early next week I will get all the parts and can put it together.

I've decided to silver solder the nipples to the pipe for added strength and just to be on the safe side bought a couple of extra ones in case I melt them.

Time for the next installment.
I received my 1/8 pipe and union nuts today as they were only coming from the eastern states. I'm still waiting on the lubricator from the UK.

I've just finished making up the pipework from the boiler to the regulator.

I decided to silver solder the nipple onto the pipe for extra security.
I used tenacity flux and my 0.4mm medium solder from my silver smithing and my mapp gas burner and it soldered up very well.

Here is the results.
I probably will leave the regulator unattached as I don't want to drill out the rivets in the boiler.

Will do the rest when the lubricator arrives.
