Nice cylinder head shot.
What microlight would these have been used with.
It's a French origin vintage (1930's) flying death-trap called Le Pou du Ciel.  There is a whole lot I could post about it, but maybe not right here among the pistons :)

I would be wanting to source pistons that are made for cylinders that have been bored out and honed to +0.020 inch

Thats putting the cart before the horse !!
Workshop manuals tell to ALWAYS  have the pistons in hand, and thus to bore to suitable dimensions.
Having said that, why don't you contact JP with a photo of your pistons, and enquire.
They recently supplied me with a pair that weren't even in their catalog, and were most helpful.
It did cost, but even common pistons seem to have skyrocketted in price everywhere lately ??

Since they do all the manufacturing, they could control the diam to the size ye seek ?

Honestly, I really did put the horse first. FW Thornton said they did T35 pistons made by JP Pistons. Size would be 60.8mm +0.020" with the correct 5/8 pin, and they would send them to the re-bore company (Saunders in Cadnam) with their regular delivery, saving me the long journey. Saunders did the lovely job on the re-bore, to fit those pistons, and then I discovered how Thorntons had got it wrong!

You are not wrong about how the prices have soared.
JP Pistons have replied. The piston, they say, looks like a Douglas AE10003, and there is an information sheet (attached)
They have one casting that will make this as a new special piston.
The price for a new special piston is AUD$600.00 per piston assembly (includes rings, pin & circlips) + postage & handling.
[ Translation to GBP is 311.22 each!! ]
That is 622.44 before shipping, and handling, and (I guess, VAT) .
We are up to 746.93 for the pair before shipping!
The GHC heritage centre get my work on the engine for free, but I am pretty sure that that much for a pair of pistons will stall the project. I think it's just too rich for us!

I am a LDMCC member now. If, one day, I get this together, then Douglas enthusiasts are welcome to be my guests at Lasham, and let us start it up, if anyone  can face swinging a propeller!

Because the photos of the parts and the identification comments that people make about those parts, will be of interest to Douglas enthusiasts in the future.

Hi Alistair,

When items are sold, just post a message in the topic indicating if all items have sold and what is still available in the batch, if any. Then an admin will come along and add more prominent wording to the topic subject line (eg SOLD) as needed.
