Barry Bucknell is my hero
Update : The local-ish supplier (went there on my bike!) - the sheets had more plugs than you can imagine, on both faces.It does seem that way from the comments here this morning and the searching I've been doing . . . . looking back the 18mm B/BB board I bought for the table (including cutting, I collected it) in July 2020 was £101 + VAT - today's price, with cutting and collection, is £211 + VAT.
There is a semi-local timber merchant that is listing 18mm BB/BB Birch ply at £119 + VAT + cutting . . . I'll probably go and have a look at that, as I can look through the stock to find a sheet that will be OK for the table?
A bit more research on Stretek and I've ruled it out as being too soft for a table top - the original Birch supplier looks likely to get the order and I'll just have to close my eyes when I pay!!!! AND with some lateral thinking from my wife the original table is going to be repurposed as a bench for use with the table so not wasting the original investment.
