Thread: Plumbing 2 injectors
19/09/2014 10:57:20

Yes, you need a clack on each injector.

If the original clack is on the backhead you may be able to fit a double clack which would be a better option than two inline clacks feeding into the original. I did this on a loco I worked on.

Hi Clive,

No, Dolgoch wasn't in LLAS.


Thread: What did you do today? (2014)
12/09/2014 21:40:19

EDPM is used for pond liners as well so must be pretty safe around water. I bought one recently for a wild llife pond.


Thread: Piston rings or graphite packing ?
12/09/2014 00:12:38

For steam use Viton seems to be the prefered material for O rings. I gave up on O rings for piston seals a long time ago and now use rings made from PTFE for gunmetal cylinders.


Thread: Jubilee boiler stays
10/09/2014 13:54:22

Hi John,

As Julian says, you will be really struggling to silver solder stays now the backhead is fitted. Access will be difficult even with oxy acetylne/propane. There is nothing in the boiler regs that says you cannot use Comsol in a boiler but unfortunately some boiler inspectors make their own rules.

You might find the construction of my Helen Long boiler of interest as that uses threaded and nutted stays:


I theaded copper rivets for the stays which wasn't difficult to do, much to my surprise. The heads are actually silver soldered outside as that was easy to do but the firebox ends have brass nuts fitted and then caulked with Comsol.

You do have to keep a watchful eye on the water level but it would have to get pretty low to melt the solder.


Thread: Myford secondhand machine prices
05/09/2014 15:06:55

I bought my ML7 new in 1973 from the old Reeves when they were in Marson Green? I paid about £150. No motor but the price included tray, raising blocks, 3 jaw chuck, tailstock chuck, vertical slide, and a set of lathe tools. I was on a course at the time and when I came home one weekend the lathe was in the front room. The chaps from Reeves had delivered it to Derby foc! It's been in constant use since then and is still going strong. The only thing I've replaced is the cross-slide leadscrew and nut. It's now got a 3 phase motor and inverter though which has improved it no end.


Thread: Seeking recommendation on new Live Steam Locomotive
02/09/2014 13:33:39

Hi John,

As Julian says, choose a loco that you actually want to build. If not, you'll soon lose interest. My philosophy is that a 4-6-0 is no more complicated than an 0-4-0, it's just got more bits to make and will take longer! You can get a lot of parts such as frames laser or water jet cut which will save a lot of time.

Britannia and Don Young's Black Five are both good designs and many have been built. The Duchess by Michael Breeze is also a good design but it's a big loco with a lot of work. The boiler is quite complicated. Galatea is horrendously complicated as it is based on works drawings and will take a long time to build. It's not a design for the faint hearted.

Blackgates don't sell the B5 drawings as Reeves have the copyright on the Don Young designs but anyone can sell castings as they are not copyrighted.


Thread: Making a Tender water tank
20/08/2014 00:09:04

Carr's do a very useful range of soft solders with lower melting points than the usual plumbers solders. Joints require less heat with less chance of distorting anything. I've used their 145 solder on tanks with either the appropriate Carr's flux or ordinary Bakers fluid. I've also used standard electronics 60/40 solders but the resin flux makes a bit of a mess.


Thread: Re bushing boiler
12/08/2014 09:27:53

Hi Mark,

It would be possible to drill out the old bushes and fit new ones or silver solder in a bush that can be rethreaded. The silver soldering might be best done with oxy acetylene to keep the heat local. Depends where the bushes are.

Can you not simply tap the bushes the next size up and make/buy new clacks to suit? Alternatively, drill and tap the bushes to as large a size as possible and fit threaded adapters to bring the thread back to original size?

Thread: What did you do today? (2014)
10/08/2014 20:19:19

Hi Brian,

Good work!

I notice on some photos that you haven't put a 2½" gauge rail in. Are there any plans to do this or have you decided not to bother with this on the new site?


Thread: Denham Junior serial numbers
10/08/2014 19:55:50

Hi Steve,

Right, here's some photos:



feeds must not.jpg


I realised as soon as I took the photo of the speed plate that the serial number is on this plate! I would guess that the serial number you have found is not the Denham number but a Ministry of Supply. MInistry of Defence, or similar number. The crown would suggest this. Mine's got a brass plate on the door which says Ministry of Supply with another number on it.

Mine is 8205 making it 1943 which seems right to me.

Anyway, hope the photos are of some use.


PS must clean those plates up!

09/08/2014 21:31:28

HI Steve,

That's looking very nice indeed smiley I remember I had a right job to get the saddle gear box etc. to pieces! That extra centre height would have been useful on mine as I could have then used some big indexable tool holders that someone gave me. As it is they are too thick.

I'll collect my camera on the way home from the pub tonight and get those photos for you tomorrow.

I notice that your workshop floor is blue as well so I don't feel so bad about mine now!


08/08/2014 20:32:08

Hi Steve,


Glad the write up was useful for you smiley

My camera is at my brother's house at the moment (I left it in his car!) but I'll get you some photos of the plates as soon as I can.

I upload photos into an album on this site and then import them into a post using the black camera icon at the top of the reply box. Think there's been quite a few posts on how to do this.

I found an image for the change wheel plate that goes on the stand door on the web somewhere so I'll try and find out where it is. Mine doesn't have that.

Edit - just realised the changewheel chart is on the site!

Hi Steven,

Ok, found a number but it's pretty much worn away. The first two digits are 10 and the third looks like a 6. According to that would put it around 1958 but I'm wondering if I'm reading it upside down. It must be earlier than that as it has a plate on it saying it was reconditioned in November 1955.


08/08/2014 00:39:36

Hi Steven,

Thanks, I'll have a look tomorrow. I did have a quick look earlier tonight but couldn't see anything obvious.

Re the brass plates - do you mean those on the various control levers? If so, I can take some photos for you.

Mine is ex Ministry of Supply and came from the Royal Radar Establishment. A friend of mine, sadly no longer with us, bought it from a government surplus place 40 odd years ago and it sat on his garage floor all that time. It had been refurbished in Leicester before he bought it and was still covered in thick protective 'goo'



07/08/2014 21:48:10

Hi Steven,

I can't remember finding a serial number on mine when I rebuilt it. Whereabouts is it?

Ordered some paint and thinners from Craftmaster Paints yesterday and they arrived this morning smiley


Thread: 5" Speedy, LBSC v Don Young
05/08/2014 09:30:56

Hi Mark,

The big problem with Speedy is that the valve gear as designed by LBSC is very poor but Don Ashton has designed a new version which gets over this. Don Young may have had a go at it as well but you should go with Don Ashton's version. He's the bees knees with valve gears.

There is a good thread running on the MECH forum by two people building Speedys which you may find useful.


Thread: What did you do today? (2014)
05/08/2014 00:31:32

Hi John,

I recognise those, especially the steel Sweet Pea boiler. They're from a deceist model engineers workshop that I helped clear a year or two back. The widow got in touch with someone I know and asked if we could help. If I had known she was just going to scrap everything that was left I would have made an offer for them sad There was a load of laser cut frames as well. I spent hours sorting all the castings out and putting them in separate boxes!

I bet she got bugger all for them as well.

That's where my Boxford shaper came from.

At least you mangaed to save them before they got melted downsmiley

Thread: Flat Silver Steel
31/07/2014 20:53:13

Hi David,

I got my stocks from RS Components some years ago as the usual ME suppliers only seemed to have it in the 2 inch wide sections whereas RS have it in smaller sections. Their prices aren't bad either. RS list it under tool steel. I believe it's oil hardening chrome vanadium steel but cuts and machines very easily.

Sheffield Gauge Plate have it in a greater range of sizes but they want £12.50 postage for orders under £200.

I use it for valve gear components as well as slidebars. It's hard wearing even when left soft. Got that idea from Don Young.
