Thanks Bugbear.....another factor!
I have now arrived at the price of the box = cost of one brass screw.....so 10p or reallly upmarket at 15p each. Wood - home grown, time - home grown, tools - ancient second hand + 40 years ago, have forgotten the polish and wax so another 10p. and possible a bit of coloured felt, say 10p. Total value 30p to 35p. and I'm not a tax avoidance accountant.
Cut a block of Apple on Saturday and brought it into the house to see if there is going to be any movement..... and was it hard. Easy to see why fruit wood was used for cog wheels. Sanding is nearly a No No. Thanks to all.
