25 pounder wood seat

Thanks Phillip, looking forward to it.

I have the same problem with mine. The seat looks like a giant cake!

Kind of what I don't want. They have some nice laminated pine at home depot for a decent price, but it is 3/4 thick. I think that will be too thin and sandwiching it will end up 1-1/2 thick which might be too much.
I thought of buying a couple wood barstools and using the tops off them.

They are in stock at Dirk Leegwaters site, but between the Euro exchange and the postage, they are a little too rich for my poor blood.

Does this image from the Identification List for Ordnance, Q.F. 25-Pr., C Mk. II on Carriage, 25-Pr., C Mk. I also Carrier Dial Sight, C No. 18, Mk. I - 1943 help?

Well it does show that the seat overlaps the metal base, so it is likely pretty close to 12" diameter. It does not solve the unknown of the thickness.
I note the dozens of screws holding the wood to the base in your photos Ed. My manual does not specify the length nor even list them. Does yours?

I have seen two styles of seat bases here in Australia, we copied the British gun and made it better.
One base is the full width of the wood seat and the other is smaller and is recessed flush into the wood seat.

Photo is of a reproduction seat, incorrect but I will fix that in the future when the custodians throw money at me.

I wonder if the metal plate is smaller than the 11" on mine.

We also copied the British gun and made lots of Canadian substitutions and manufacturing changes.

Unfortunately nothing on the screws or the seat thickness.

Phillip emailed me the measurements of his seat: 11-3/4 round and 7/8 thick for those that want to know.

Ed: Your scan shows around 23 screws. My base only has the inner circle of screws that I am able to identify, so there may be some variance on the designs.
