I’m actually shocked. The advice seems to be not to buy any more right now, and to work with what I’ve got while I work out what I need. This is not the type of measured, considered, non-acquisitive attitude I expect to hobby forums (most experience I photography where Gear Acquisition Syndrome is a real thing)!
On balance I think I’ll get going with what I’ve now got, and then as time proceeds move across either to ER32 or as Clive suggests, a fleet of Weldon pre-mounted cutters. The chances of me ever changing this mill is slim to none – there’s no way I’ll have the space for anything bigger, and also no chance of me (as a hobbyist) exceeding the capabilities of the mill!
