knock down saw horses/ trestles

I’m currently working on a project that is simply too big for my workshop. So I made some knock down trestles that I could take outside and put the project on when the weather is permitting. Lately that’s been quite often.
They’re made from some 70’s chipboard I got from some old cupboards a friend asked me to dismantle and take away. I tell ya, they don’t make chipboard like that any more ! It’s tough ! There was also blockboard and ply used in the cupboards, all very good quality. A good haul in all.
Fairly basic construction on the trestles. I think the pictures are fairly self explanatory.
They do the job.
