she seemed pretty cheesed off…
Did you see her expression after Michelle Obama hugged her a while back?:eek:
Gooday All
You can sometimes find interesting writing when you start stripping aeroplane parts.
TFC’s old Yak had newspaper used between the stringers etc & the fabric. The print had transfered from the paper to the airframe parts so it was covered in arabic from Egyptian papers…
At least I think they were Egyptian…:confused:
The amount of pistons i have thrown to scrap & never thought about making ash trays although not merlin pistons, but with the smoking ban in the uk not much point now.:dev2:
Was at a motorcycle salvage yard one day & discovered 3 brand new high comp MTC pistons for a Kaw 1000. They were just laying in the dirt, but clearly unused. I got em for free as you need 4, not 3 for a set.
Fast forward about 12 months or so & on another visit to the salvage yard discovered the 4th one, also free π
As seen here on top of my Connie piston…

Can you do a quick measurement of the diameter of your piston?
It’s a hair over 5.7in, so it’s either 1340, 2800 or 4360..
Hi ZRX61. Thanks for the pfoto of your R1830, which is exactly the same as mine. Now, as regards those piston rings……..

It appears to be a flat topped R2800 piston judging by the size.
I don’t smoke, so my Merlin piston is still intact…:p:cool:
& no, thats just polished, not chromed….. I’m not one of those chromo-sexuals π

Looking a bit optimistic with the drop tank on the P47…. ;):D
If you want radial engines parts (AND have the part #….) This warehouse is like that scene at the end of Raiders of the Lost Ark.. but it’s ALL engines & parts… & 99% of it is NOS… I’m like a kid in a candy store when I go there..

If you don’t have the part # you could just say “I need a set of knackered rings for an R1830 piston please! whatcha got?”
Bore/stroke sizes:
R1340: 5.75in x 5.75in
R1820: 6.125in x 6.875in
R1830: 5.5in x 5.5in
R2800 & R4360: 5.75 x 6.00in
R3350: 6.125 x 6.312in
I’m totally confused now…..is this an R-1830 piston? :confused:
I have no idea, lemme measure it…
ok, it’s about 5.7in so it’s probably another R2800 piston
Same *team* as the one in March…
Hi ZRX61.
Have you a photo of the inside of the flat top piston please.
Thanks.

Flat top:


Flat dome (Connie):
R2800:
Yep, not exactly much variety with design of large American aero-engine pistons! π
Well, some of em are flat on top…

& some have a flat dome…

Some sort of boat?
Here are a couple of photographs of my R-1830 piston…..at least I hope itβs an R-1830 piston! :rolleyes:
I’ve got R2800 pistons that look exactly like that…
Well, the lower one does…..

The βmasterβ connecting-rods for the R-1830 are particularly impressive if you can get hold of one.
This pair are 1820…right one is unused.

Slowly cleaning this up… Got most of the burnt on oil off by plastic blasting(it went BOOM! clatter clatter clatter…..pop, clunk)
