G'day Chris
I admire the work form my "armchair".
Can you please give me some details of your gas-air torch.
Regards Ian

Brazing Torch. Hello Ian, It's a Flamefast. Very similar to the RF-80 brazing torch shown here, but I think it's the predecessor as the valve knob is in a different position, and it's 20 years old. It uses natural gas, and is only just 'man enough' for the job. Chris www.flamefast.co.uk/PDFs/Rf10-rf80-gas-torches.pdf

Hi Chris, Excellent work as usual, keep going! cheers Paul Thanks Paul. I am keeping it going, but slowly. I put the other side stays in today, and all went well,except for a little 'blob' but I can remove it. It happens. I like this ' silver solder in a ring' process as it seems to give better penetration. I'll get on with the backhead ready for fitting, but have decided to fit bushes for the firedoor hinge screws to screw into. So it looks like ordering some 3/16" dia. phosphor bronze. I assume that's what you used on your backhead? Chris

Firedoor. Because I enjoy firing and driving these things: the backhead layout is pretty important to me. I've made a start on laying out the backhead in order to enable ease of access to the controls. I've fabricated the firedoor hinges in the past so this time I decided to machine them from stock, and I enjoy using the rotary table, which made easy work of the hinge pin lugs. Everthing lines up much more easily, as can be seen. Just a 'clean up' and I'll be ready to use them to position the blind tapped bushes for affixing them to the backhead. Yes, It'll look better with another rivet as well. Chris

Model Engineers Thumb. I'm 'lurking', but thought I should post something in case anyone is looking for my obituary. I've got 'model engineers thumb'. I can't grip anything due to an inflamed thumb joint. I must have the cleanest workshop in the Midlands, all done with my left hand. This is where I was when it 'struck'. I'd been working on the regulator, prior to fitting the backhead, just to make sure the regulator bush is set up at the correct angle so that I can silver solder the backhead in place. I'm on the 'look out' for some heat conserving firebricks ready for the 'big heat'; thumb recovery permitting. Chris

Nice to see an update, keep 'em coming...and remember ....a sore thumb is a sore thing, but a sore thing isn't a sore thumb.

Cylinder Hone. I'm still 'lurking'. My 'model engineers thumb' has not yet made a full recovery. Boredom has set in, so I couldn't resist messing about with a pair of B1 cylinders that required machining. I bored them on the vertical mill with a boring head. I'm not yet convinced it's the best way to bore. Springy boring bar and all that. I tried one of those things that was mentioned on here a few weeks ago: a brake cylinder honing tool. As can be seen, when any load is put on the spring tension, the three honing block want to twist. Has anyone used one with success? Chris

I've used one successfully in the lathe, mounted in the chuck with the cylinder on the cross-slide. I was told it was important to keep as much of the length of the stones inside the bore as possible and to keep moving it back and forwards. The finish looked good and the bore was parallel as well as I could judge.

I've just used a 2 stone jobby on my piston valve liner bore - as recommended by Simplyloco (I think), I clamped it in the chuck and hand held the cylinder block moving it in and out, but not letting the stones come out beyond their fixing pins.
The resultant bore was beautifully smooth :-)

Mike, I think you might be referring to this. Still No Tube. If I can't lay my hands on a piece of tube in the next week or so I shall have to roll one up. Baggo was right - 4 1/4" tube is hard to come by. Anyway - quite a while ago I bought an unfinished boiler off ebay. It was going dirt cheap, no one seemed to be bidding, so I had it, knowing that it was costing me less than a set of tubes for my Bantam Cock boiler. I intended to cut them off and use them, and I could have also used the barrel. But It's too good to cut up, otherwise I would be on with my V4 boiler. Looks like making 'Heilan Lassie' next, so as to make use of it. I'll get it in the pickle tomorrow ready for close inspection. So I might be jumping ship for a while and carry on with this boiler to keep my hand in. I'm not building Hielan Lassie, but I am building a 3 1/2" Gresley V4 2-6-2 'Bantam Cock'. Well , I was up until October 23rd when my thumb became inoperative and have not worked on it since although I have been modging about in the workshop as a therapy. I should get back on it soon now that the workshop is a little more inviting. Yes, Heilan Lassie was in ME about 1959 to 1961 ish. I must have the odd copy of that period as I recall reading a little about it, but I don't have the set. So, as it states - 'looks like building Heilan lassie next', thumb and good health permitting. Chris.

Slanting Boiler Bush. I should get back on it soon, now that the workshop is a little more inviting, thumb and good health permitting. Chris. So I am back on it. I thought I would have a play with the A1 boiler by making the backhead. I've drilled the holes and made the bushes. Now - when I fit the regulator bush, the axis has to be horizontal, and the backhead slopes at an angle of about 15 degrees. This leaves a gap at the top, as in the photo. Has anyone found a good solution to prevent this bush from moving during later heating? Although it's a tight fit I don't want it lying down flat on me after inserting the backhead because it needs to be on the horizontal axis for the regulator to meet the wet header. I put a wedge in the V4 boiler - but I don't really like it. Chris.

Gresley's V4 Steam Manifold. I haven't done much on this for months. That bad thumb put a stop to things, and I don't think it will ever be the same. Old age, too much workshop use and the like must be taking its' toll. Even though I haven't yet soldered the backhead to the boiler, I've been having a go at the steam fittings to break myself back in, so I decided to give interest parties an update. Here's a few bits for now. Chris.

Hi Chris
Liking your progress, I suffered hammer rash to my thumb last year smashing it really bad with a lump hammer, that bad I shattered the bone. Boiler is coming along well, looks very professional, what are the 3 very small bushes for if they are bushes that is.

Door Hinge Screws. Hi Chris Boiler is coming along well, looks very professional, what are the 3 very small bushes for if they are bushes that is. ace Hello ace. The three small bushes are blind tapped holes, 8BA I think. They are for the screws that hold the door hinge and the door latch. I'm still looking forward to a progress update on the Gresley V2 in gauge one! Chris

Hi Chris
That explains it. Like I said earlier in a topic somewhere I know nowt about trains.
My V2 is still waiting for me to get stuck in to it but I just have so much on at the present, preparing my models for the Harrogate show this weekend trying to get my 'project' loco up and running and on to the track that I am building....slowly.

V4 Grate and Ashpan. Hello JB. You've been missed! I haven't done much on Gresley's V4 in the past few months but hoping to be inspired by your return. We must still be 'neck and neck', as I am also working on the grate and ashpan. I've secured mine by including a cross member behind the backhead. A long allen screw holds it up, and with a couple of turns, lets it fall down. The cross member also secures the rear of the boiler, stainless screws into the lower extended backhead plate below the foundation ring, allowing for expansion, and also supports the front of the footplate. Chris.

Two loco's at the grate and ashpan stage, looks like things are going to be very interesting on the forum for a while. Great work Chris, I'm looking forward to further updates.... Pete

Only too Pleased. Hello! I've been reading your post for a while now and i've just decided to make an account... i'm also building a LNER V4 in this gauge... Thanks for all the help you've given me! To think it's of interest to someone, but I haven't done much to it recently. I'm hoping to finish the boiler soon. Don't forget to post some pictures of your progress, no matter how small or slow. We like progress photos on this site. Chris
