Hi All

Im looking into converting my pedestal drill (PD) like this one

http://www.machineryhouse.com.au/Products?stockCode=D140#

into a pedestal drill and a modified milling machine by using

http://www.machineryhouse.com.au/Products?stockCode=D140#

this compound table, albeit that the PD has 2 thou runout at the bottom of
the taper shaft.

Any comments?

Anyone from downunder using the above compound table from Hare & Forbes, if
so whats the quality like?

I've tried the same thing but with a heavier drill press. Its barely
acceptable for light plastic or wood. I know of a guy who uses a much
sturdier xy table with a heavy gear head drill press, its ok for plastic
jobs but not much more. Depending on your expectations it might work for you
but it didn't for me. :(

they are chinese manufacture. they do work but are bloody awful.

you'd be better off keeping the drill as a drill and buying a small
mill.

check the rest of the hare and forbes cattledog.
my son has the little HM10 and it seems a nice piece of kit for the
size. one of my mates has one for making model aircraft engines.
I have the HM50 and I'm quite happy with it.

Better yet, dump the cheesy drill, and buy a Chinese mill drill.

They make a really fairly decent drill, better than an average working
guy can find, in general these days, and they already have a drawbar, to
keep the chuck from coming adrift at speed.

Much to be said for that last bit!

I don't think the spindle of any drill press like this is up to the task
of milling. It's not designed for side loads. And I think you'll have
a tough time keeping the #2MT tooling in place. Next issue is using a
drill chuck to hold an end mill. The end mill tends to pull down and
out of the chuck, no matter how hard you tighten it.
I have used an old Craftsman drill press with an X-Y table for years
and wouldn't be without it. It's on the table 99% of the time. In
fact, I even have a simple wooden table, 8" X 10", glued to a piece of 2
X 6 that I clamp into the vise that's on that X -Y table when I need a
flat surface. That way I don't have to take the X -Y table off very
often and the wooden "table" can be considered sacrificial. ----So, I'm
not against the X -Y table, I just don't think you'll be happy with
using that tool for milling.

Many, many years ago I had a project where I had to mill a 1/8" slot
in steel and I got away with it. But I had to take tiny cuts. This
drill press, by the way has a threaded collar on the chuck that pulls
the taper up into the spindle so it can't come loose.
