Delta 17 " drill press with VFD

1943 3 phase drill press running on 120 volt house hold power

[@phooesnax]

thank you! I love seeing what you are up to and what you are Jack O fying! You do tremendous stuff.

[@American_Made]

Great press, I just bought same one not long ago I am in process of rebuilding it, tracking down parts I need. That one you have is a really nice original complete machine. I see the foot press too. awesome drill press. I need that badge and several other parts.

[@maydanlex]

I like the explanations you provide here. Subscribed.

[@jackEnglishmachines]

+maydanlex thank you hope you find more useful things here. thumbs up on the sub.

[@OllyParryJones]

Love the depth stop idea.

[@hyperborean.]

Very informative, thank you so much.

[@goshnodo]

Look at that young guy

[@jackEnglishmachines]

jon i got this drive from Factoymation. for a brake the VFD is the way to go for anything 3HP and under. the stock dynamic brakeing is very good but you can add a resistor and stop an elephant

[@phooesnax]

Nice machine. Have the same unit with number two taper and jacobs, 3/4hp 3p 1955 and the FM50. Little wary of running past 60hz. Also was warned not to go too low. I set low limit at 20hz. Bearings sound a little rough on your though. Only complaint on mine is the standard table has no slots for clamping. Nice job.

[@jackEnglishmachines]

the upper bearing is on order the only one i did not change.LOL it is a great press. I don,t see any problem over running the motor up to 120 as this would just be a 3450 rpm motor. my motor is 1 hp and i am not worred about running it lower for short time periods. thanks for the comments

[@roofermarc1]

Second time I've watched. I like very much.

[@dannersmyers]

Is the lower nut on your depth gauge necessary? Can't you just use the quill locking lever to keep it in place? I have a 1957 delta 15 just wondering your thoughts. Very cool press and a great job!!

[@jackEnglishmachines]

yes you could use the quill lock but then you would have to unlock to go down. Also i like the quill lock set to take the play up in the split casting bore of the head and do not want to move it . this drill here is set to less than .002" of play in the quill bore

[@roofermarc1]

I would like to see that table you have built for the press. Also how have you wired the existing switch, I'm assuming a manual starter, into the drive? Is it considered a disconnect now?

[@jackEnglishmachines]

+Marc Lewis Yes its a 2 wire control to the vfd control side. its used just like a light switch. I just like the look of the older switch even tho its over kill. table is nothing special but the production table below it sure helps support that large table

Why would you record such an interesting video with your radio blaring in the background? Maybe it's just me and I'm too easily distracted so sorry for bringing it up.

[@jackEnglishmachines]

+spidersinspace Its because i don't care that much what the you tube ethics are. Making flashy video as a living is not my thing. Lots of them to be found if you're here for entertainment;) . glad you found it interesting but there may be a radio on in my other VFD videos . Peace out

[@whitacrebespoke]

spidersinspace I didn’t notice it till I read your comments

[@jonrfreeman]

Where do u get your vfd. Looking to add one to a table saw for the breaking feature or is there a easer way to achieve an electric brake?

[@danielosmon]

I had no idea you could convert 3 phase down to 120v single phase. Are you running the cat5 from the potentiometer to the tranfer switch, bypassing the main on/off switch? I appreciate the lock set-up for the quill, nicely done

[@jackEnglishmachines]

yes, I sell VFD's check out my playlist for wadkin temple VFDs . 120 V input are capable of one and a half horsepower on a regular household outlet and up to 3 hp on higher amperage outlets output, 240 V three phase.

[@mnsterbruiser]

I just bought a similar 1946 Delta press I'm told is 3 phase. Motor tag is completly worn away can't read it's specs at all. I noticed you swapped your motor. I'm assuming because the voltage was higher. What motor did you go with? Why did you swap? Love the Vfd setup.

[@jackEnglishmachines]

+mnsterbruiser As you guessed the old motor that came with my press was 600 volts and though you can run 600 volts with a VFD it is more costly (3 times the price)than a 240 volts motor. The cheapest VFDs for single phase input run 240 volt motor and only 240 volts for 110 volt single phase input. I picked up a vintage Rockwell dual voltage 220/440 volts 1 HP for $50 and wired it at the motor for 240. Some times your switch gear can tell you the voltage of your motor if the tag is gone. there is often a wire diagram in the wire junction of the motor too. Is your motor OEM?

[@mnsterbruiser]

+jack English machines The tag on mine is still present and I can make out a few of the faded letters. But, all of the stampings are gone. It's a rather large motor much larger than a coffee can. It says Delta, ball bearing, Double Duty. It has two random letters EL punched in about the middle of the tag. Three wires coming out of the motor all the same color Black. I'll pull the box cover and see if I can find additional markings. Thanks for the tip.

[@jackEnglishmachines]

if there are 3 wires its a 3 phase motor. there may be 9 wires in the motor if its a dual voltage. how these are connected configures the voltage the motor runs on. look here i284.photobucket.com/albums/ll29/oldtool1/motor%20delta_zpswumucupk.jpg

[@mnsterbruiser]

+jack English machines Opened the motor box and I have several wires with number collars just like that badge. So I definitely have a motor with dual voltage. Was your 600v motor dual voltage as well? I still can't determine what dual voltage motor I have unless the only dual voltage motor ever made was the 220/440. Might just buy a Vfd and see if I can get it to run then I will know I guess. Thanks for the help, very hard to find this info online.

[@jackEnglishmachines]

yours will be 220/440 . 600 volt is a single voltage winding motor and would just have 3 wires at the motor not 9. How they(dual voltage motors) work is the winding in the motor always see 240 volt its just a matter of the wiring of the winding Leeds(all the 9 wire numbers) in the motor . what the diagram is showing is there wired parallel or in series that why the voltage on these motors are double 220/440. All dual voltage motors will be that way. you want yours wired for 240 as per the motor tag . if you want to run your 240 volt 3 phase motor off 120 volt regular plug this is the drive you need. www.factorymation.com/Products/FM50_115V/FM50-101-C.html
