Thread: Allchin outer wrapper
21/12/2020 13:44:43

Hi and thanks for the replies

I may have mislabelled the parts I bought as part built as only one of the tubeplates was silver soldered and it was scrap

I hope the pictures I have will upload okay

The wrapper is too long by 3/8 but the previous builder has cut the stay holes before reducing the size

I was thinking of cutting each side, removing the excess and but joining the sides back together

My other option is to buy a new copper sheet which will be in metric 2.5mm and make a new wrapper

I bought a pair of half built allchin boilers from the well known site

I have found, surprise surprise, that the outer wrappers are wrong

In a nutshell the stay holes have been drilled in the wrong place

But the wrappers are also too long so the problem could be fixed by cutting each side, removing the excess and re joining the sides back together which would bring everything back into line

This would mean a but joint either side with a strap on the insides

My question is will this be a safe way to fix it

Thanks in advance for any advice

What am I doing wrong


Thread: Photo copies of articles

Is it still possible to purchase photocopies of previous articles from the magazine

I used this service a long time ago and wondered if it was still available



Thread: Westbury wyvern / centaur
14/11/2020 12:53:31


I have a part built wyvern engine that is missing some of the castings, namely the valve levers and inlet /exhaust

As the centaur engine is a similar design in the head does anyone know if they are Interchangeable or can anyone help with the dimensions of these items?



Thread: Heinz kornmuller de dion engine
10/10/2020 19:56:41


I have recently started working on the castings for this engine

I bought them a long time ago from the designer in Austria

There are no construction details on the plans but I did get a CD with lots of pictures

I have come to the point where I am ready to machine the crankcase half's but there is no wat to hold them in either a 3 or 4 jaw chuck

The pics on the CD show all machining being done on a mill, the castings are almost to exact width as received with

0.2mm over finished width

My question is has anyone tackled one of these engines before and if so how did you go about machining the crankcase half's

Any advice would be greatly appreciated

Some time ago I bought a set of castings for this engine from Heinz Kornmuller in Austria

The set came with a cd of photos and drawings

I am just about to start making the engine but the drawings are all in German with no translation, I also have an issue with the drawings not printing correctly, can anyone tell me where I can buy a set of these in English ?



Thread: primus blowtorch

Hi, I have a primus blowtorch which has a blocked jet, I have tried to clear it with no joy, the jet is marked 07, I have searche the web but cant find any replacements. Can anyone here point me in the direction of anybody who might sell spares?



21/09/2019 10:17:18

Thanks Jason

Thats what I was looking for, I thought I saw refrence to it being in the magazine recently but must be mistaken

Thanks again

Hi, can anyone help with details of the issues containing these articles so I can order some photocopies ( is this service still available )

If not if anyone can copy them for me I will pay the costs



Thread: anealing piano wire
10/04/2019 18:45:51


Your dremel suggestion was going to be my next option. I have a lot of clips that would work in a grove as you suggest but as this is an axle for a model aeroplane I'm worried about side forces moving the clip, my few experiments have shown a little side force can release the clip

Thanks for all the replies, i'm going to persist in trying to get it soft enough to drill

Thanks for the info on the manufacture of piano wire Clive, now it makes sense that my heat reatment has only limited succsess but with enough drills and enough time it wont beat me


10/04/2019 16:42:51

I dont need to re harden it, its just at the ends for a split pin to hold the wheels on

I've ordered more drills !!


10/04/2019 15:38:56

As the title says I need to anneal some piano wire to drill a 1/16" hole through it

Its 5/32" dia and I have tried heating to cherry red and holding it there for a bit then cooling slowly

This isnt having much effect, iI have blunted all of my drills so far

Any advice?

Thankyou for all the sensible replies/advice

I'm going to send me inverter back to drives direct to see if it can be repaired then take it from there

Thanks Again
