Sensitive drill press

I've been looking for a sensitive drill press for ages to use in my hobby of clock making, the FEW i've seen are all 3 phase and the motor an integral part of the machine (so a motor change is not on), were their ever any single phase ones made ? David

Yes, also machines with separate motors, but your whereabouts may
determine which makes may be available.

I have an old 1/4" Jones and Shipman sensitive bench drill that's been
converted to single phase. Uses an ordinary foot mounted motor.
A point that I would raise is that a lot of the commercially built
sensitive drills - AREN'T!!!
My little J&S (and a pretty similar Meddings that we had at work) uses
a rack and pinion feed for the quill just like a conventional bench
drill. Not really sensitive enough for the really fine stuff, for
which a lever action feed would be better.
Probably the best advice I could offer is to consider building a
George H. Thomas universal pillar tool, as covered in his "Workshop
Techniques" book. The kit is available from Hemmingway, here:

Cheers, Scruff.

A three phase motor on a small drill is not automatically to be rejected.
Check that the motor is marked 240/440 volt. It should have six terminals
under a cover plate. Wire this as delta mode 240 volt.
connect two of the terminals to 240 live and neutral and an 400vAC rated
capacitor between the third terminal and one of the others. The value of the
capcitor should be about 40mfd/hp of the motor.
You possibly have to spin the chuck to start the motor but it should run OK.

Steamer, I'd forgotten about that sort of attachment. There are plans
on chris Heapy's site (archived here:http://tinyurl.com/29ffp6) for a
similar one. It's a few items down on the workshop projects page. It's
a pretty handy looking thing. Hopefully I'll get round to making one
eventually.
Cheers, Scruff.

Myford sell a similar one for use in the tailstock of the 7 series
lathes.

Handy. What method did you use to provide the rotational drive to the
chuck as it slides up and down, please?

Re: Sensitive drill press

--Ah. It's store-bought and modified. I think it's just referred to
as a "sensitive drill attachment" or some such. It consists of a Jacobs #0
chuck on a stem that slides inside a 1/2" rod. It's got a spring to retract
it and the back of the chuck has a bearing with a ring pressed onto it. To
operate the ring can be grabbed and used to push the chuck down into the
work. My widget fastens onto this ring, then provides a lever a little
farther away. Will check the big catalog and get back with a part number.

Re: Sensitive drill press

--Yeah, found 'em in a couple of catalogs. Travers Tool has
something called "Accu-Driller" 'sensitive hand drill' and they sell them
for as little as $54.60, but one with a decent chuck costs about twice that.
Their part number for this one is 63-003-205. In the Rutland catalog it
"Hand drill feed with chuck", model# 5000 2200 for $115.11
Hope that helps!

Thanks. I'll have a look at those.
