Hi Richard
My magnetic screw driver has been a great help when I've been working with small screw sizes. I got mine with a big set of drive bits: **LINK**.

I didn't have an alley key that was the right size, so I bought an iFixit driver kit in the end. I didn't want to risk stripping the screw head with a flat head screw driver that only went across two of the points.

If you have not already spotted them, Zander-Heba have drawings of some of the variants at 1:40 scale. Those available are listed on that site under their Prussian class types, G7.3 & G8.2 & G8.3. Tenders attached to these locos were 3 T 16.5, 3 T 20 or 2'2' T 21.5.
If you wanted to model a loco in the 56.2->8 series then you would have to source further information as the boiler is on different mountings being further forward and higher. I think!
As I'm sure you know there are a number of videos of the preserved Tr5-65 (= war reparation BR56 to Poland) on youtube.

I think Zane should inspect the security set as Mine does not have triangles, better safe than sorry.

Top of the thread has gone walkabout! First post is Zane asking where he can get a triangular screwdriver to fix his sons Thomas loco. Neils answer is as above and Zane has replied to say he never thought of a allen key.
I tried to paste it in from a list of Zane's posts but the formatting goes to pot.

Managed to paste it as an image.

HI Zane,
If you google 'security bit set' you can get a whole selection – check the type you need is included. The other option is to file down the end of an allen key.

Hi,
It might be worth contacting this precision engineering company to ask for advice and get a price on an oversized collet? : **LINK**

Progress. A couple of days ago, Mozilla 'forgot' to renew a certificate, so all (security) add-ons for the Firefox browser were disabled. Gmail has recently thrown a wobbly. Pilots fight and lose against airliners' safety-enhancing systems. Auto-piloting cars crash, for no apparent reason. Algorithms of Byzantine complexity make decisions too quickly for errors to be identified, and no-one understands what the hell is going on. The stock market has a 'blip'. Machine 'intelligence' learns by implementing heuristics it has 'learned' by processes no-one understands or can identify. Therefore no-one can tell whether the AI is correct or not, except by results – when it's inconveniently late for an error to be detected. And some of the mistakes are extraordinary. The prof. of security engineering (how's that for a concept?) at Cambridge won't touch internet banking.
It was nerve-wracking enough sitting in the passenger seat when junior was learning to drive. Luckily, instructions to go slowly were heeded. But how would it feel to be a passenger in an auto-piloting vehicle, with super-human reflexes, seeing all around itself, and making decisions far more quickly than the hapless, half-asleep and de-skilled human 'supervisor' possibly could, and speeding along, perhaps at speeds beyond the ability of any human driver, particularly in a complex environment. And yet the human is presumably expected to be able to take control as soon as (s)he senses that the AI has stuffed up. How relaxing to be a passenger!
And then there's the worrying problem of the AI's 'moral code'. Who gets sacrificed in certain accident situations (eg the owner, in a head-on smash, or the queue of people waiting at the bus stop, if the car swerves to avoid the head-on)? Will you be able to pay more to have a 'protect the owner at all costs' rule programmed in?
Since most garages seem incapable of sorting out existing misbehaving control systems, we can look forward to chaos when our electric vehicles have a slightly intermittent contact somewhere, or a bug that rarely manifests itself…
Progress? It's too easy to build complexity into software. Features are added 'because we can', and it doesn't cost much. But 'because we can' is not a good justification for doing something.
Rant over – for the moment.

I have a couple of Warco machines, a WM16 mill and a WM250VF lathe, and I am very happy with them – I think!
However I was at their open day yesterday. They had a Smart and Brown lathe (not familiar which model, but it did look nice), and two Harrison mills (one horizontal, one horizantal/vertical).
No room for them in my workshop. and it would need a more substantial floor.
But I could have had a excellent pair of substantial quality British machines for around £1500 total, delivered.
So I think if I were setting up again, but also only if I could accommodate them in terms of size and weight, I would opt for larger second hand British machines, if only one could find them at the appropriate time.

I have acquired drawings form the Heba site and started to cad up the locomotive.
I have some questions about the horn block and axle block and would be thankful for some insight into the design. Why the wedge and adjustment screw? Maintanence? take up wear? other?
I have attached a picture with arrows pointing to what I am asking about, I hope it is clear enough.

I drink Kenyan – can be a delicate taste – suspect the mix of roasts has just enough bite from the high roast not to overpower the more delicate low roast which might well be destroyed by a No 4 roast – the local roaster to me was lost years ago – now its either Sainsbury's beans/grind or the somewhat higher roast Waitrose which IMO is not as good.
My father brought me up on Chagga AA from Tanzania. I've found the Sainsbury's Original Blend bean is not half bad as a standard coffee.

Hmm ,yeah, better plan, get a bigger workshop.
My son & I have a bigger workshop, with a mezzanine floor on about one third for storage. 20 x 10 ———– metres, and still not big enough. VBG

Mine is a 5 x 7 metre fully insulated with attic…… and it's bursting at the seams, trouble is there's no more garden left now. hmmm, maybe down into the sandstone?!!!!

Zan: I completely agree, though this assumes one can get hold of a 34T changewheel, as I don't have the facilities for making one myself, at least not yet. I sent a message with the specification to HPC yesterday. Let's see what they can come up with.

I used to use the same sort of thing, but now they are in the bin you will magnetise the tools when drawing them off the holder ruined a very good expensive calliper this way. Don’t do it. Use wood with drilled holes.

a plane is to cut it must be razor blade sharp. Putting it face down means that it will be in contact with a bench which may have hardened glue etc. bonded to it so any pick up which moves the body will blunt it against this rubbish. So it makes sense to put it on its side. What… you say. My bench has no such rubbish! It’s perfectly smooth! Ok I say don’t damage the bench then with a sharp plane blade….but if it’s like my bench it’s piled with tools so putting it on it’s side means that it cannot be put onto another tool which could and I say could damage the fine edge and produce ridges in any planed work. Why take the risk? The old practise of putting any plane on its side was and still is good practise
A sharp plane will really sing to you when used. When used on a hard tough wood it won’t take long to need honing why take the risk?

As an addendum:
Zander-Heba have general arrangement drawings drawn at 1:40 scale of all the Prussian Br55 variants in their catalogue.
The 8.1 is here.
The 3 T 16.5 tender is here.
I only had a brief scan-about, but may be worth you having a good look round the site if you think the drawings may be useful, as, as written above, all the Prussian variants seem to be there…. example. I have not spotted the later DR 'heavier'(??) type, but I expect it may well be there somewhere. Maybe it is one of the types listed on this page showing equivalent classifications and a search in the 'Prussian Freight Locomotives' for the correct Prussian equivalent will turn-up suitable drawings. Alternatively you can ask Zander-Heba of course.
There is this copy of Eisenbahn Journal which is relevant if you do not have it. Click on the lower thumbnail labelled in red 'PDF Dateien' for an list of contents and an excerpt to show you what is in the mag' (Apologies if 'teaching grandmother to suck eggs'!). Maybe worth seeking out a copy if you prefer paper to an e-book..
The (seemingly!) definitive book is listed on this page. At a variety of prices – postage shown is within Germany, ask for UK rate. There is one listed on abebooks in the UK at present at just under £40 p&p included.
This site may whet your appetite. Look down the list on the left and click on 'lokliste', then click on Bundesbahn-/Reichsbahn-Dampflokomotiven & scroll down to the '55' section for a couple of pics of 5" gauge Br55.
And, lastly, there is this 5" gauge kit of the Br55, also available finished in 'Prussian' KPEV livery by Zimmermann. Don't know if they might be prepared to sell drawings, parts, whatever, etc.

Phil

Gerry, you may also want to ask on this forum, there are several there who have made that engine or have the castings for it as well as the person who can supply castings. I'm sure they may be able to help you and may even have some full size drawings as Mike who does the castings have made several other Anzani variants – Fan, W and 6 cyl radial.

I undertake work for a range of customers around the world to design models from 1:1 down to 1:350 scale. These models are either plastic injected or resin cast, sometimes made from wood for the 1:1 items.
I'm currently working on a full size replica of the Fokker V.40 sports plane of 1919. This was powered by an Anzani Y engine of 35hp. I have little detailed information about the engine, and have seem some 1/4 scale versions of the engine, I've contacted John Chenery who has given me the details of what h has available and its cost. I will be buying the drawings.
What I would like is copies of the Model Engineer magazine articles relating to the build of the engine. Does anyone have the following: 4022, 4024, 4026, 4028, 4030, 4034 and 436 magazines?
Much appreciated if anyone can help.

Not done it….. shame you have had bad experiences with the sc. 4 jaw. Mine is brilliant, but non round stock? Bdms is quite round I have experienced no problems.. often people are expecting micron precision for the price of a bacon butty .
I can take a piece of work out, put it back ( which I avoid at all costs) and it’s within 1 thou without any special precautions , I like bacon but my chuck is a basic level TOS chuck and I stand by the accuracy statement
If you use extra pieces to bulk out to a square shape for the 4 jaw s.c chuck, double sided tape is a great aid to hold it all together while setting up. Still think the faceplate is best though
Edit, …blasted autotype with technical terms on the pad!
