i have a harrison 12" swing one here, i bought a mint M250 a few yrs ago and stored it at the time. i pulled it out 18myhs ago and wired it up and set about turning some 30mm stock, it was at that point i realized just how good a lathe my 12" was, the 250 is a great wee lathe but it aint meant for anything more than light cuts. that monarch is a fine lathe, you would rarely see them about, wouldnt mind one myself but the next lathe im buying here when i get the money together will be a 2.5 mtr bed in either a harrison or a colchester with a big mouth on it. so i was right enough about the collet system, dont know how i remembered that. i take it you mean it is now converted to an r8 taper instead of not.
