My Isokern tube is still as good as new and ready for the next boiler

Thanks guys, lots of useful information. The Claud wil be my second loco, the first being a 5"AJAX. That has a pair of 3/8 axle pumps with a similar sized boiler and cylinders. Nothing against injectors (yet!) but I like the simplicity of the axle pump in maintaining a steady waterlevel.
Cheers

John,
Many thanks, I'll pm you about the castings.
Going back to the tender axle pump if I use sufficient one way clack valves can I tee this into the 'handpump' feed and just have a single connection to the loco?
Cheers

I'm just about to start to build a 5" Super Claud (Martin Evans design). The boiler feed is shown on the drawings as two injectors and a tender hand pump. I'm keen to fit an axle pump instead of one of the injectors but there is probably not a suitable place on the main loco, the front main axle is full of eccentrics and inside cranks etc and the rear is directly below the firebox / ashpan so not idea. I was wondering therefore whther it would be ok to fit an axle pump on the tender with a suitable coupling to the loco? My main concern is that the load on the pump will cause the 'undriven' tender axle to lock up, am I worrying un necessarily? Thanks

Probably best to tap a thread into the hole (even if you have to open it out slightly more) and screw in a bit of threaded bar of the same material, a dab of loctite would be a real belt and braces job.

I would appreciate some guidance, I picked up a set of four bogie frames from a car boot sale for a tenner with the intention of making a braked 5" riding trolley. I assume they are not for a locomotive and that they are for rolling stock Does anybody recognise these and / or suggest where I could find a suitable drawing? Many Thanks

Pete,
Thanks for that, I did wonder why the Glen appeared to be a smaller engine. At the end of the day there does not appear to be too much in it, I'll wait and see what if any castings turn up second hand between now and the Autumn.

I'm starting to plan what to build as the next project. I want a larger engine having already built an AJAX but would prefer a shorter wheel base just in case I ever get my way for a garden track.
I think a 4-4-0 such as Maid of Kent, Super Claud or Don Young's Glen would perhaps be the best choice as well as appelaing to me visually.
I would hugely appreciate any thoughts on which would be the best of those three. If anybody can point me in the direction of build articles for Don's Glen that would also be great.
Cheers

Just a quick question,
I need to order some comsol and flux to seal a couple of hard to get to boiler pinholes but most suppliers seem reluctant to post the flux. A few suppliers hint that Zinc chloride is the flux and seeing waggy's post it would appear that Bakers fluid is also zinc chloride, now I can get this at my local hardware shop so can I use it or is there a difference?
Thanks

Having just had a new chimney and flue built onto the house I was left with a spare length of chimney liner. We used the Schiedel Isokern system which comprises various diameters of basically pumice tube. It's soft enough to cut with a hand saw and with a few additional bits of vermiculite board all sorts of arrangements can be made. I think it must have cut the heating time by at least a half as well as made everything much more comfortable. The liners are not cheap at about £25 a length but having used it I would not hesitate to go out and buy another length specifically if I had to do a larger boiler. Just make sure you get an inch or so bigger than the boiler barrel to clear any bosses etc. Attachments:

Could you use plugs (inside the tube) rather than caps?

A nice braided stainless steel flexible brake pipe would look quite neat and no problems with pressure. Thinking about it the tube will only be at boiler pressure whilst actually pumping, the rest of the time the boiler clack valve will ensure there is no pressure in the pipe.

This could be ideal and will share a lot of tooling with the Myford. I saw it on Lathes.co.uk and was almost tempted myself
For Sale: RAGLAN vertical milling machine in remarkably fine, little-used and original condition, even to the maker’s paint. Variable-speed drive, an unmarked 21” x 5.5” table with three T-slots and coolant trough. Metric micrometer dials, No. 2 Morse taper spindle, 1-phase motor fitted from new giving speeds from 380 to 2400 r.p.m. Complete with collet chuck, a Myford machine vice, work-light and some cutting tools. Quite possibly the best surviving example of this handy little machine. £775 Phone: 01388-608132 or 07891-325631 Machine located in County Durham. Pictures of the milling machine for sale here and details of Raglan milling machines here

Well I finished the workshop a few weeks ago, brick walls, double glazing and 8" rockwool in the roof, almost better than the house itself. Can't get to work today so have to entertain myself at home, hmm I wonder where I can go?

I have previously used drain cleaner but my batch seemed to leave a black greasy film on the copper , I'm now using citric acid crystals, you can purchase these by the kilo in any home brew shop, it may take a few minutes longer but it certainly won't do me too much harm
