All new to me - but it comes with 4 plates with the numbers 24, 30, 36 and 40 ?

They all look the same to me so any help advice on how to use would be welcome

Looked on you tube but no wiser.

Thread: Is Model Engineering in Decline

I don't know about model engineering being in decline, but this model engineer has been for years...

I suspect that perhaps a fair percentage of members, like myself, are in their twilight years. A poll of members ages would be interesting.

Sadly, it seems to be . My friend in Cornwall tells me five years ago there were three clubs in Cornwall, now there is only one.

Moved from meths to butane Ceramic burner and silver soldered gas tank. Much cleaner.

I make small pot boiler types etc up to 3 inch diameter.

I use the vermiculite blocks as per Jason's post and a propane supply with Sievert equipment.

The Sievert items are sourced from Hamilton gas products in Ireland - very helpful people and will supply complete set . 7kw burner I find more than adequate,

May be worth giving then a call .

See if this works - two WG bushes and injector seperate on RH side of top WG bush. All the other models are like this so totally confused.

Thanks Jason - penny has dropped. I stand corrected.

Jason thanks for correcting me

I would add a picture but cannot get into my album - I always seem to have this problem

I get

Bill see my answer in the other thread, Only one bush for the lower water gauge fitting on the drawings.

Same person asking?

Edited By JasonB on 14/10/2019 13:42:42


Jason, you are right. Same person - same question and similar reply from me on this thread.

Yes realise only one bottom bush for WG but I was replying to his injector take off question which I believe is the inboard bush by the top wg bush ? Please correct me if I am wrong.

It may be worth looking at Station Road Steam archive traction engine section .

If you input Allchin in the search box there are plenty of pictures of boiler backheads

The bush for the injector is the seperate one to the right hand side of the top water gauge bush approx 1/2 inch away.

Hope this helps.


14/10/2019 12:03:32

This question came up recently in another thread and I admit I am confused as to why ?

The drawing shows two bushes on the left hand side of the backhead for Water Gauge only.

I am sure that it’s been said before but I feel it needs repeating, you get what you pay for, pay next to nowt and you will get rubbish, pay a good price and you will get good stuff, pay top dollar and you get top quality.

With Baz on this one - extremely good advice.

My brain is on the same wavelength as Howard's

I did it by drawing the equilateral triangle with 65mm sides then mid point of sides to halve the 60 angle gave me mid point of the triangle. Measure from centre to one of the triangle corners and got 37.5 mm radius. ie 75mm diameter.



”My brain is on the same wavelength as Hpward's”

Apparently not, Bill

You used elegant geometrical construction [which is subject, of course, to draughting & measurement errors]

Howard used calculated trigonometric functions to reach a good approximation of the target value.


Sorry Michael, but to my simple mind drawing it out with a ruler and a protractor is simple to me as opposed to elegant. May we just agree to disagree.
