Thanks to everyone who responded to my question about boiler
insulation, I have found a source for ceramic paper material in 1/16
thickness.

Would you care to share the source?

The ceramic cloth comes in a sealed bag and it was $75 for several

Probably less expensive, if you don't mind importing it from England, is the
ceramic fibre insulation from GLR Distributors

Sorry for the delay in answering.
To correct myself on the A3, there wasn't much play in the valve gear,
it was in the reverser and the linkage to the valve gear, more for my

well now.

Rebushing the valve gear is possible, but if the holes in the linkages
are worn away, there's no real way to be certain that they are worn
equally in all directions, so drilling out the holes for the bushings

slightly farther apart
Hi Geoff.
This e-mail is not aboot insulation although might as well add my
thoughts ( I use glass insul ie what is used in house wall insul ;; it
supports the lagging and at the same time gives that air gap that all you
guys mention ) .
No I have had a puzzling problem pop up
Hi Graham,
Ref. Insulation.
Do I understand you use both glass and lagging. i.e. use glass
insulation, it supports the lagging?.
Is it a two layered sandwich?. What is the lagging material?. How
thick? Which areas do you use it?. Which engine and fuel?.
Would appreciate a few
Hi Geoff
No the insulation is just wrapped around the boiler in every location
and held in with thin wire to hold in place while I wrap the lagging over
the top ' ;; there is a small amout of movement wich helps prevent denting
;;; the insulstion is the pink material wich comes in 8X 2
Hi Tony
The insulation is of glass fibre ( the orange coloured sold in 8X 2
foot panels 4 6 inches thick ) ;;; the thickness on the boiler is in the
region of 3/32 to 1/8 and loosl;y packed ;;; then I use aluminum sheet
clamped ontop of the insulation .

The sandwich idea really appeals to me! Sandwich-like structures

Dear Friends,
I have about 2.0-2.5mm space between the boiler and the
jacket and I wonder whether insulating the boiler would
be a good idea and what the best material for this would be.
I am considering ceramic sheet like the one used for the
smokebox insulation or mineral or glass wool
I've used cork without any ill effects.

Wool felt was the material of choice among builders in the UK way back in the
good old days. I have used it on a couple of locos and it works well and holds
up (surprisingly) well.

I can't give the web-site reference, but boiler lagging tests by Chuck
Hackett in the larger scales showed the following -
adding a jacket, giving a trapped air gap, made a difference
adding insulation ie. lagging, produced NO additional benefit.

Hi,
Could Fibreglass (woven or matting) as used in boat building be used as
lagging?

Re lagging, I note that the Aster KGV kit had no insulation around the
boiler--just an air gap. The burners and smoke box had insulation, of
course. The Flying Scotsman doesn't either, yet both locos seem to run
just as well as those with insulation (ceramic sheet or asbestos) . The

that the fibreglass cloth meant for fibreglass/resin
lamination (grp) is pretreated with materials to improve its adhesion to
polyester resins (flammability?)

Midwest provides a piece of fibreglass mat in its steam engine kit for
boiler insulation. The yellow
at the smokebox/casing join area. Which apparently
was caused by the builder using a glass wool/fibre glass insulation as a
replacement for the generic ceramic sheet, which the builder normally used
on other engines. And similar to the ceramic sheet Aster suppliers with
their kits.
