Peter Jones Loco Works #5 Mamod 0-6-0 RUTH ANN

Superbiker_uk · Post by **Superbiker_uk** » Sat Sep 15, 2012 4:11 pm

This one has been such a long time in the works. Tribulations of another kind have hampered progress and Mamodification has taken the back seat over recent months. BUT... I am now very pleased to have finally completed this 0-6-0 Mamod called 'RUTH ANN'

...and here in a more 'natural' setting:

Converted Mamod locomotive to 0-6-0T configuration using Dream Steam high pressure copper boiler, gas firing with BIX burner, pressure gauge, Goodall filler valve, Dream Steam upgraded gas-flowed cylinders, Roundhouse lubricator, laser cut custom designed 0-6-0 frames, coupling rods and cab back (by Peter Jones), sound by Summerlands Chuffer

Peter,

Another fine Mamodification from the Peter Jones Locos Works. I love the sound that the Summerland Chuffer makes. Does the SCGP1-25 chuffer just push fit onto the 1/8" exhaust pipe? Would be good to get one which could be transfered between my fleet of Mamods, MSS & IP Janes.

Is the Cab front a cut down Mamod SL or MSS one, or is it the cab that was sold as an upgrade for the IP Jane/PPS Janet (the whistle on the front is the same as the one IP Eng fitted to their IP Janes)?

Is the brass steam chest a commercial item and if so from whom?

Like the water tap on the side tank - where does that come from?

Thanks for sharing this great loco.

Chris Cairns.

Hi Chris - thank you for your appreciation.

The Chuffer does sound good doesn't it. It would be even better when running under load. This video was the first one on the track though and only the second boiler fill since completion of a single run on a rolling road so it needs more running in yet. The SCGP1 is a push fit onto the 1/8" exhaust so can be removed if required. It is easier to fit if you have a removable stack. This Mamod has an non-standard saddle and stack fitted to the standard smoke box so it made fitting of the chuffer relatively simple.

Is the Cab front a cut down Mamod SL or MSS one, or is it the cab that was sold as an upgrade for the IP Jane/PPS Janet (the whistle on the front is the same as the one IP Eng fitted to their IP Janes)?

There's nothing that would get past you re: Mamod/MSS - yes very well spotted it is an upgrade cab set-up from an IP Jane. I thought it would be just right for this loco and think this modification may well feature again on one of my locos. You can still buy them from Roy Wood Models unpainted so I think i will get an order in

Is the brass steam chest a commercial item and if so from whom?

Yes this is a commercial item with some modification to fit over the Goodall valve. I will have to look back over my records to see where it came from. When I find out I will let you know.

Like the water tap on the side tank - where does that come from?

That little water tap serves two purposes - to get water from the tanks of course but it also was to hide a paint defect

a nice little bit of detailing and also I am no longer 'bugged' by the inclusion that was in the finish (i drilled though it and fitted this tap

).

They come from Brandbright - Dummy Test Cock cast brass pack of 3 (RSA95 £5.15). There is just enough brass on them to tap a thread and bolt them on. That's what I did and I have fitted the other 2 to the the front of the tanks on my Salem "River Class".

Peter-

Wow, WELL DONE!

Technical question, it appears you had to "cut down" the main rods on the cylinders to make them shorter? And if so, did this change the geometry of the port plate port openings?

I ask as still like the "locobox" approach of extending the main rods to the rear driver, but I have yet to figure out the port arrangement using the online steam motor design software.

Just the other day I got the files off of a hard drive that crashed back in '08. On that drive was a 0-6-0 Jane/Janet. While interesting, it was not as well executed as this.

Not quite. Cylinders are standard geometry as are the port plate settings and openings. The frames are specially designed and made - the loco is actually longer than a standard Mamod and the smokebox and boiler sits higher than on the standard Mamod. This is for a number of reasons but primarily to create more clearance between the combustion chamber and the wheels.

When I built this I wanted it to still be a Mamod so all that is required as 'special' parts are the frames, coupling rods and the half cab back.

Thanks, I see now, from some of the photos, the rods looked shorter in others.

Again, great work!!!

So really, one could transplant their engine's upper half, strip the frames of the fittings, and then add them to the PJ 6-Star frames to achive the same [provided they also got the rods and 3rd axle] ?

It's not quite that simple but close. You do have to cut the standard body work by removing the part of the side tank that forms the 'floor' inside the cab. These then have an extra hole drilled in them and are fitted further back and higher up on the special frames. The other matter than is to make a new connection from the now 'floating' side tanks, rigidly back to the frames. This is done using K&S 1/4 x 0.14 square brass tube. You cut it to make some small angle brackets and then fix to the square tube.

Hopefully the pictures speak for themselves:

An important piece of the finished loco is the special cab back that I designed to hold everything rigid and square. The top pair of holes affix to the original rear tabs on the now separate cab floor pieces and the bottom pair of holes go in the normal place to affix to the standard rear drag beam:

Excellent Peter.

Many thanks for sharing those images. Just proves that there is a lot of work involved with your Mamodification projects.

What sheet metal do you use to make the cab back?

On the subject of cab backs here are some images from 2 IP Jane's I have showing how IP Eng designed their cab backs.

A IP Eng cab back fitted to an early IP Jane. This has an integral box fitting to replace the function of the rear drag beam fitting in a Mamod SL loco to hold the chassis frames together.

At the end of the IP Jane production IP Eng ran out of components and used a lot of Mamod parts, like the side tanks and a rear drag beam. So here is the cab back fitted to one of those late IP Jane's.

And adding some more info to this interesting thread. IP Eng had an optional coal door fitting for the IP Jane, and even made an optional tender as well. Fortunately I kept a copy of an eBay photo showing this coal door (the tender is just out of shot on the LHS).

These items used to be in the PPS catalogue for the PPS Janet - wonder if Roy Wood Models will do them?

A very nice model indeed.

Superbiker_uk · Post by **Superbiker_uk** » Mon Sep 17, 2012 9:43 pm

What sheet metal do you use to make the cab back?

I am using 1mm mild steel sheet for the frames and other body work parts. The only issue is bending it nicely so I have a simple 18" bench mounted metal bending brake for this purpose.

BTW - thank you for the information on the IP Eng parts - very interesting and the pictures are very useful. I like the original half cab back with the rear drag beam replacement piece 'built in'. Very good idea that.

I am having some half cab backs made that fit the standard Mamod to go with the coal bunkers that I had made to my design. I am stocking up for Mamodifications 6,7,8 and 9 :lol: :lol: :lol:

Interesting... The design is better than cutting down the Mamod one like I did. While it works, it is wiggly being held on by the buffer beam and mouting tangs alone.

Thank you Chris for the info on the rear door design, did not know that was an IP original. I always liked the Jane tenders, they were better sized then the MSS ones honestly.

What a good job Peter has made of Ruth Ann. As I've been mentioned in several of the replies and have been having an email conversation with Peter, I thought I ought to mention that I can supply many of the spares and upgrades for Mamod/MSS/IP Jane and, of course, my own ex-PPS Janet. I have a current price list but it doesn't include all the bits I have partcularly current parts for Jane - all of which are, or will be, available. Also I am developing new products and welcome further suggestions. I hope to have my website up and running before too long.
regards

Hi Roy - thanks for stopping by and welcome to the forum! It's great to find a supplier for these parts and look forward to doing further business with you for parts. Mamodifcation number 6 on the way

You can see some of my other creations here: http://gardenrails.myfreeforum.org/about5220.html

Agreed, great that Roy came on-board. I bought his new connecting rods for Jane/Janet/Mamod/MSS locos and they are nice.

Excited to see what other Mamod/Jane upgrades may be in the works from Roy, and what other projects Peter has in the pipeline.

Peter,

I hope you have a good supply of those Brandbright brass items - whilst looking for your drain tap I notice that a lot of their brass items are no longer available or whilst stock remains.

Roy Wood wrote:Also I am developing new products and welcome further suggestions.

Welcome to the Forum Roy.

One item that many of us use is the replacement steel wheels. These were originally designed by IP Eng as multi holed disks. Sadly the holes were dropped over the years and we now have some boringly plain steel disks instead. What is needed is some form of insert which would enhance the look of these wheels. These were available from Alan Briggs but following some major Customer Service problems he left the business rather abruptly. Perhaps dougrail can provide us wth a photo of the ones he obtained (Wayback Machine has not stored anything from www.loco-plates.co.uk - Alan Brigg's business).

Another item would be some smoke box door handles like the DJB Engineering ones.

It is not on your current lists on-line but are/will you be doing the turned brass domes for the IP Jane/PPS Janet? These are also good replacements for those lost on old Mamod SL locos, or to improve the looks of the MSS loco (it has a smaller steam dome), and even an addition to the current Mamod William IIs & Mark 1 & 2 locos.

As you will be aware the UK postage increases have killed a lot of business and it would be nice to get as many of the required Mamodifications from one source - one of the goals of the original owner of Dream Steam I believe which never really came to fruition.

I would be in the market to purchase a few of these also. I have an original one on my IP Eng / Mamod Hybrid "LUCY" that I made up with some original IP parts - I was able to purchase the remaining stock that Brandbright had a couple of years back (thanks to RWM I now have a source for some more

)

Roy - this is what we would be after:

Did the tooing for the nice little PPS Janet tender survive?
