I've got a couple of fractional AC motors in my shop (drill press and mill) -- I'd love to run the machines at a slower speed (the big bits in the press and the boring bar in the mill are running WAY too fast) short of buying DC motors, or rigging up multiple pulleys and/or leather straps up to the ceiling with other pulleys and the like, is there a simple way to slow these motors down? I recall seeing a control box for routers (I think) that would do the trick, but havve no idea if they would suit a 1/3 and 1/2 horse motor or not -- don't want to let the majik smoke outa them, after all . . ... .. thanks, all (and, jsut to head off any arguments, I am ready to admit that anyone's drill press can out run mine, anywhere, except for in Bubba's mind) | ||

I don't have a drill press so you are safe! Dave | ||

I remember seeing something like that on Myth Busters. They had some kind of control box hooked up to either a router or a grinder (I can't remember which) and they could vary the speed. They were trying to bust apart CDs!  | ||

"(Non-confrontational"  Says you! If you are rich enough to afford a drill press, then you should be paying more taxes.  | ||

"..fractional AC motors....at a slower speed" If the motor has brushes (hand drills, routers,etc) speed control is simple phase control (like a lamp dimmer), but if the motor has no brushes (drill presses, big fan motors) electronic speed control is expensive as the AC frequency has to be changed. | ||

Variable Frequency Drives can vary the speed of AC Induction Motors (the brushless type) from 20% to 100% of full speed. They are fantastic devices and are priced accordingly. You'd be FAR better off to shop for a two or three speed AC Motor with the same mounting as the ones in your equipment. Try Granger's or someplace like them for a start. | ||

I have a drill press that goes 172MPH.  | ||

I overheard a guy talking at Hooters about the new Buell drill press. But I'm not going to tell you what I heard. | ||

Give it up Bomber. I know what you are trying to do. The contact patch will remain the same no matter what speed you run the press. The mill on the other hand, will vary the contact patch, but motor speed has nothing to do with it. Hope this helps. I would explain why, but this topic should remain non-confrontational, as you requested. | ||

My 1/4 HP drill press with the racing v-belt will outrun your 1/2 HP drill press on any workbench... rt | ||

Blake -- not only am I rich enough to have purchased a drill press, I did so on the profits made by selling parts to other motorcylcists, without reporting the income to the feds -- beware of the upcoming taxes on race rubber, bud -- it could put a crimp on your activities! therefore, of course, not only am I a scofflaw, but I am also standing on the backs of the poor, downtrodden biker community! I'm a capitalist fool, er, tool! Attica! Attica! power to the man (I'm so confused!) Fly -- thanks for your information, but what the heck are you doing, actually answering a question? Same goes for you, 99 and bear -- both motors have brushes (which surprised me!), so I may be able to rig sumpin up! thanks for the guidance Glitch -- I understand about the contact patch, but let's talk about filtering the cooling fluids used on metal working equipment -- I say nuthin less than a 0.1 micron filter is worthy, and anyone that sez otherwise is a godless commie! Lastly, for my brother thang, I admit you are faster than I in every endevor, sir! (which may not work out so good for you in some venues {leer}) I love this place ;-} | ||

I'm both surprised and amazed at you Bomber, a 0.1 micron filter? And here I thought you'd use an old hankie to filter the cooling fluid through and use an old oil can to hand pour the filtered fluid onto the part being cut. Just what is this world coming to. I know of an old woodworking shop in Auburn California that still uses leather belts to run their equipment with all the shop's machines being run off of one big engine downstairs. | ||

edison's shop in winterhaven fla has the same setup -- we've gone there 3/4 times over the years, and the girls just leave me be and come back a couple of hours later when it's time to lock the joint up . . . .. . big old 5 horse motor in the shop corner, lathes, mills (horizontal, natch) and a HUGE shaper -- they've never let me run em, though ;-{ actually, I filter the fluid through my teeth and spit it on the metal, buit that didn't seem in keeping with the newfound elevated level of discourse found around here, so I lied | ||

| Road_thing |
Brer Bomber, I take your point, but I doubt we're playing in many of the same venues! Filtering the fluid through your teeth seems like it might have dire consequences...do your teeth leave a ring of lube around the glass you keep them in at night? rt taking cover... | ||
| Bomber |
ROFLMAO -- with regard to venues, I'm thinkin we're lucky that our venues let us come home (not wure I would, in their places ;-} ) nope, no ring . . . I soak em in Kroil! | ||

I'm sitting in a Greek joint in Astoria Queens. I'm not sure I understand EXACTLY what these folks are saying but it SOUNDED like "All hail Dan Hurda for engineering the Revo powered drill press". Greeks will probably buy it, modify it, drill the heck out of materials it wasn't designed to drill, then sue the manufacturing claiming "non-fitness for purpose" or something under the Magnuson-Moss-on-a-rolling-stone Act. It's all Greek to me.... | ||
| Bomber |
thos Magnum Mosses would pack quite a wallop if you double loaded em, I hear I'll stick to my LeMat | ||
| Newblaster |
Didn't Anon say that there would NEVER be a Revo-powered drill press? | ||
| Bomber |
Newbie - only that they woudn't be marketed in democratic wards, I think | ||
| Newblaster |
Ahhh, I misread. My Blast with street tires will still beat a drill press. | ||
| Blake |
  Thanks guys. Humor is good medicine. | ||
| Cj_xb |
This thread had me laughing soooo hard, one of the best one's I've seen !!!  | ||
| Newfie_buell |
The hell with you all, My Drill Press has a Light Bulb that I screwed in MYSELF | ||
| Glitch |
OK Bomber, the filter don't matter that much if yer usin' synthetic! Just remember that during break in the press may smoke a little unless you use dino first. Oil cooling through the teeth forever! | ||
| Court |
>>>>My Blast with street tires will still beat a drill press. Yeah...sure...maybe on your home workbench, but how about a neutral workbench? The drill press will win everytime on my bench | ||
| Phillyblast |
No fair, Mr. C. You have Court's Home Advantage. | ||
| Bartimus |
Bomber, I have a few Frequency drives that may work for you. ping me... BBB | ||
| Bomber |
Bart -- you've been pinged (pung? always had trouble conjugating irregular verbs)! Thanks for any assistance you may be able to render also, all else, you guys were right, of course, no brushes in these motors, so a dimmer thingie is out . . . . .. . |
