I scored a bit of kitchen bench top that had been cut out for a sink.
Nice thick water resistant chip board with laminex on one side & melamine on the other.
It wasn't big enough for a router table so I chopped it up into squares on the band saw to turn it into threaded face plates for vacuum chucking.
I have 2 different lathes with 2 different spindle threads so I made 3 for each lathe.
I borrowed a couple of big taps from Jim (powderpost).
I used my big bowl jaws to hold the blank while I marked it out & cut the hole with a small scraper.
I planned to have the laminex side up against the flange on the spindle as I though that side would stand up to the compression of being tightened up longer that the melamine side would.
If you look at the 4th & 5th picture you will see that I made a little step inside the hole for the last bit of un-threaded spindle.
I used a big shifter to hold the tap & get it started on the lathe & then I removed the blank & finished it in my hand.
Once it was threaded, I reversed it onto the lathe spindle & cleaned it up.
I have some epoxy timber preserver that I plan to use to seal the bear chipboard edges & thread. It comes with a thinner so it soaks in & once it is set, I'll get it a couple of days before I stick it back on the lathe so it doesn't end up stuck there.
