Thats sounds like the same collet as my Gorton O-16 uses. Its
known as a (gasp!) Gorton taper...which means its unique, and
somewhat hard to find collets for. The included angle is 20
degrees, the nose diameter is 1" +- .002, I think. The biggest
collet I could find for it is 1/2", which is a problem for all
but light duty projects. Other than that, the O-16 has been a
great machine, mine wqas built in 1954, I've had it since 1983,
and that spindle is still real smooth, the scraping in the ways
still looks terrific as well. But, all in all, I wouldn't buy
another one...accessories were still available, for a price, at
the time I got mine, but now its a scavenger hunt.
