Can you use a horizontal milling machine as a surface grinder?


Dunno!


Anyone got a BCA milling machine? Any good? What collets does it use?


They aren't milling machines, they are small jig borers. Could be used for
_very_ light milling, but think in terms of clock making rather than traction
engines. I've got one that I inherited from my father. It needs working on to
make it usable (I don't know if it was a wartime expedient or a lash-up, but
the feed screws currently appear to be 7/16BSW...14tpi!!). It will be sorted
once the Hardinge HLV, Beaver mill and J&S 1400 grinder have been done, so not
for a year or so...

The collets are Lorch "long series" that are about as common as rocking horse
sh1t, since about the only things that seem to use them are BCA's, and
Boley-Leinen jig borers

Thanks

De nada :-)
