I've been pestered into making my granddaughter a tabletop to go onto a Singer sewing machine cast iron base.
The brief was, "Just get something she can do crafting and homework on, can be plywood or whatever but 1000x500 in size".
I've had a bit of 18mm plywood that size kicking about for a while and more recently have been cladding the inside of a building with engineered oak flooring (not my choice but there you go) so have some offcuts which just happened to be about 1100 long...
The boards are fairly rough as they look like they've been fired through a bandsaw at running speed but I can sort that, free boards are the best price though.
First of all I used some Sikaflex I had spare off another job to glue the flooring to the ply and secret nailed the tongues where the nails wouldnt get in the way of any cuts I needed to do.
Not showing the photo of the Sikaflex stage cos in the tradition everyone with a mastic gun my granddaughter wrote her name with the Sikaflex.
Anyway, I left all the boards overhanging the plywood so I could cut it later, left it dor a day for the Sikeflex to go off then the next day I planed it flat, using a toothing plane going across the boards at 45 degrees or so. Didn't have to be my toothing plane but I've hardly used it and I just wanted a play.
Then went over the parts where the grain was ok with my No3 record handplane and the parts with the reversing grain with a 112 scraper plane (the first time I've ever used one of these and yes I was just having a play with it) to minimise tearout.
Its all just on a couple of bits of offcut 100mm square oak beams ontop of my sawstools, in the back alley cos I'm short of space.
