Re: 3 phase power plugs/outlets
I hope I¡¯m not hijacking this thread but I¡¯m currently trying to sort out the line connections on several 3 phase machines running off of my 20HP Phoenix rotary phase converter . For the record i¡¯m a complete three phase dummy.?
?I just commissioned a new k700 and the instructions specified that the manufactured leg ( i assumed this to mean the high leg from the rotary converter) to the brown wire on the attached power cord. This prompted me to double check the placement of the manufactured leg on my 2004 RL160 collector, 2000 F700Z shaper and 2008 Exact 51 planer. Can anyone help me determine the correct placement of the manufactured leg on these machines?
Thanks, Chris

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.

I would be inclined to use a two speed motor and

Two belt changes and high low speed on the motor

?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.?

Re: 3 phase power plugs/outlets
Mark,
I was merely saying that the following statement is wrong:
¡°It takes voltage in that is 180¡ã phased, and shifts to 120¡ã phased¡±
No phase converter does this. A static converter (I doubt anyone here uses one) does create a phase shifted (delayed) signal to start a 3 ph motor but it still does not take 180 deg phase voltage and shifts to 120 degrees.

Re: AD941 dust hose attachment
I have the Felder 90-degree 120mm to 120mm hose elbow. I bought 120mm hose so didn't need an adapter. My only complaint with the Feldor elbow is that it is a "hard" 90, nothing at all sweeping about it.?

I¡¯m just connecting flex ducting that has the reinforced spiral wire that coils through it. Wanting to make a direct attachment. ?
Some have mentioned they use Felder¡¯s right angle adapter, but I don¡¯t see the need on my situation to use a right angle adapter.? Just a straight tapered adapter would suffice. ?

Re: P coupling Felder adapter to Hammer
Thanks for the responses, I have come across your parallel fence which is very nice but unfortunately haven't been able to afford them including the shipping as im based in Aus. The one from Felder is in country and interestingly enough a little cheaper per unit price but its not a DRO.
Hi Bram thanks for your suggestion, ive found some other forum posts of people using aluminum extrusion and other things such as incra positioners, rulers etc which seem to function quiet well without adding too much lateral weight bearing on the t-slot.
Thanks,

The right angle connector part number 02.0.020 is a snug fit due to the taper.

Bill does offer a 120mm to 4¡± hose. See link. But it¡¯s not a right angle. ?
Now if he offered a 120mm O.D. to machine connection, then it curved 90 degrees to an end that excepts a 4¡± hose, well then FOR ME that would be the ¡°Holy Grail¡± of adapters! ?
