Garrison?
This drill press is pretty handy could be better at the moment the turret has issues so I use one spindle and a Rohm hand chuck.?
I have 4 speed options ,high / low ,,, turn machine on ,,,start to move large spider handle,,,start in slow ,,, so normally do nut use center bit just let bit find center than if small diameter select by switch high speed and drill. When done raise quill back up drill shuts off. I use a low profile German Rohm vise and is mounted to a Thompson 100 xy bearing copy table . Both axis lockable manually or with electric brake . Very handy table i use 3 of them on different drills.
Also set up with foot switch for instant reverse for tapping.?
Machine is Japanese one of last made .?
Currently setting up rise and lower of head when out of stop set tange with 12 v DC gear motor from wheel chair and chain drive .
Vari drive. Head moves on 2 -60 mm shafts 10¡± center. So no loss of position like single column. 3 phase 1.5 hp 240 volt

Thanks Mac.? I had never considered setting up a machine that
way, but I love the idea.? I'm going to look into how I might do
that to my drill presses.

Assembly drill ?I told my friend what I wanted and I did the hard
stuff he set up to do.?
Micro switch and relay I think.
Very handy my other machines it¡¯s built into the controls.
Very glad I know a young smart energetic
Fellow to implement my request, controls is not my strong
suit ?but they are his.

Hi Mac,
??? Can you provide some details on having the drill
start automatically when the handle is activated?? What
did you use?? A microswitch and a relay?? An aftermarket
product?

Also I have my drills most set up so when handle is
activated the drill starts and whe n returned it stops and
also have foot peddle with reverse although most have that
set as. Auto feature with activation by stop.

I have quite a few serious drill press, B&S
turrets , single spindle Alzmetal, Burgmaster , and
Azuma Radial 10¡± column .?
They all have vari pulley drive (reeves)or gear
drive with 2 speed motor .?
I would be inclined to use a two speed motor and
use a couple belt changes you only need 4 speeds is
way more than enough.
Two belt changes and high low speed on the motor
mor positive drive system that¡¯s what the big boys
do talking machines of course and a hell of a lot
cheaper and problem free.

?My prior drill press, a Powermatic
PM2800B with a single phase 1 HP motor with
mechanical variable speed with digital readout
was nice. ?It was not too powerful, which was
good, but my larger Forstner drill bits did not
stop rotating when cutting wood. ?However, I
wanted a radial drill press where the table
stayed fixed and I could drill holes farther
from the edge of the wood, and I could adjust
the distance chuck to wood without the table
shifting side to side like on a standard drill
press.
I went with a 3 phase vintage Delta
Turner-Walker style radial drill press that came
with a smaller motor - a 0.5HP 1725 RPM motor..
?A VFD was added. ?This was discussed in a prior
thread. ?
The VFD makes noise at all times unless the
power supply is turned off, and the larger
Forstner bits stop turning in wood, especially
at lower speed.
Plan is to change to a ENC single phase 220V VFD
along with a Marathon 1 HP 1750PRM 3 phase
motor. ?A friend has a similar radial drill
press but no VFD and does not have this issue.
He would have to change belts to adjust speed as
the tradeoff. ?I am hoping the upgrade will give
me the needed performance without the need for
belt changes.
When the change is made, I will provide feedback
on the performance.?
