drill press variable speed conversion

Great project! The quality is great. 1979 B7100DT Gear, Nissan Hanix N150-2 Excavator. My farm shop drill press has seen better days and either needs to be upgraded with a new motor and a variable speed drive or needs to be replaced all together. they heat up too fast. I had to modify the pulley's 5mm key to fit the 3/16" groove on the motor shaft. I'd get a 1 HP 3 phase motor and this VFD. I put it on a Jet 14" bench drill press that had a slow speed of 450rpm.

To make sure that this hole is exact in the centre we did made final cuts on the lathe machine as there is very limited clearance between the rotor and the stator. The reason being the face that this thing has got plenty of torque and these days you can easily find one for cheap as well. For a better experience, please enable JavaScript in your browser before proceeding. Once we dry fitted everything, the first problem we faced is rotor getting stucked to the stator as the machining of both the parts we not upto the marks so we messed with the 0.5 mm clearance. I did also have to use a link belt as the one supplied was too long. With all of this additional gear reduction, Ive got a LOT more torque available and I expect that my issues with stalling are over as well. So instead of messing up with gears and pullies we have decided to drive the chuck directly with the hub attached to the main shaft and the stator enclosed within. I have a Craftsman 17" 1.5 hp floor standing drill press I bought probably 15-20 years ago. Thanks for posting and the documentation! Thanks guys, I think I'll use the drill press alot more now. It's up to the buyer to decide where to put each pulley, and at what height. probably weather-related, time change.whatever. Absolutely amazing customer service!!! So I bought a TECO L510 single phase 115 VAC input VFD and a 1.0 hp 56 frame 3 phase motor to make the conversion. This is mostly for fun and to see what all I can do (much like most of us and our E30's). I've cut over 100 holes without having to sharpen anything! It would be cut up like crazy and have trouble staying on, I would imagine. It has gobs of low end torque. Thanks very much for the quality kit! It consists of a large offset pulley mounting plate, and a set of 4:1 ratio pulleys that will cut the speed of the motor down to a fraction of its previous setting (about 25% of original, Id say!). I bought a 10" X 10" X 6" case with a hinged cover to mount everything in. Delivery time was quick and kit was easy to install. Loop has it right. yes you have heard it right and yes its crazy. One other thing, just forget about trying to put the top cover back on. L185F, Modern Ag Competitor 4 shredder, Rhino tiller, rear dirt scoop, A very clean well thought out mod, I have to as though, what do you have tied up in it, VFD and 1hp 3phase motor, we cant figure in yoru time and odds and ends. Only pictures is not enough for a good referenceThanks! This bolt on kit will double (2:1) or quadruple (4:1) the torque of your drill press at the spindle and cut the RPM by 50-75% (2:1 4:1)! All in all, none of the issues listed above are rogue fabrications fault, they supplied a kit that does exactly as it says, and does it with a very easy and adaptable installation. I haven't thought of using an old treadmill motor and variable speed. Even though I am modifying it (Drill Press Reduction Kit), what you sold me is exactly what I wanted, and is perfect. Well like all the crazy project ideas we got, there is always a problem waiting right in the middle of the project, so there are two of them. You may have to flip some pulleys over, or mount them at different locations. I needed to lower the RPM of my drill press to allow for using a 3/4 inch annular cutter for making holes in half inch steel. But you have all the pieces you'll need, it's just a matter of installing them in a manner that will work on your drill press. I used the belt sander to make a .009" step on one side of the key. Turned a ordinary drill press into an incredible machine. That's a way better speed range for these drill presses. Buy it and have fun with your project. 310 RPM -> 78 RPM So we cut down the top half of the pully and later we flush cut the top of the adapter so help the rotor sit as close to the centre as possible. Now before we rip it a part, time to modify the motor. I have read, and IRL found, that a 3ph motor lacks torque at low rpm. Now, bits cut like they are supposed to and holes are very clean. On top of the fast shipping it also ended up costing more than I paid. You must log in or register to reply here. This page was generated at 10:36 AM. i made a youtube review, might give you a little heads up to what this kit does. Do you know what the hub motor's original specs were for voltage and amps? Just for grins I punched a 5/8 hole in a 1/2 inch plate without a pilot hole. I've had this project in mind for a while now and finally found great deal on a 1.5 HP three phase motor (thanks Chad).I bought an inexpensive 1.5KW (2 HP) vfd on Amazon as well as an electrical box to house it. Live and learn. I wish I could have had you make duplicates of all your parts while you were at it.I have the exact same drill press. there is a small 2 new pulley that gets installed on the motor itself, and the pulley stack that used to live on the motor, is transferred on top of that large 8 pulley wheel. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This works great on my Harbor Freight 20" drill press. Each installation will be different. There is a small wobble in the provided pully, but it works great and it doesn't bother me. I can easily count the revolutions as they spin by, and theres a chance that it might even be a bit TOO slow at its slowest setting. Kit bolts on in about 25 minutes with hand tools. I build lightsabers, and I have always hated being at the mercy of shapeways and other suppliers for the little parts that I need. Thanks guys! The end result is I have a standing drill press (with ceiling attachments so it won't fall over) that runs in the 300 rpm neighborhood (don't quote me on that, may be lower) that's got great torque. I really need to start collecting old hover boards. Really awesome product, just doesn't work very well with the harbor freight 13" drill press due to the way the belts are tensioned. Ratted at 10 cells and 350 watts of power initially sounds like good enough but this crap ESC just wasnt able to get the juice out of the hub motor and made us doubt the power of this huge motor. presses So we switched the ESC with a more powerful RC Car ESC ratted at 150A and 6 cells lipo. It works awesome. Didnt seem real. Some combinations of pullies will require longer belts, but i was able to get an acceptable speed with the one provided and the 2 that came with the machine. I got everything mounted in the case, twice. To controll the speed of the chuck the servo tester is mounted on the left side of the housing where the on/off switch was mounted previously. Fortunately, Joe over at RogueFab saw my previous thread posts and contacted me about my drillpress issues, and we talked for a while about his reduction kits and how they would be a low-cost way to give me better cutting capabilities, and finish up all of those 2 speedholes in the monolith crossmember. 435 RPM -> 109 RPM Later we filed the edges to make a good clearance between the stator and the shaft adapter thats going to hold the rotor. First drilling i did with the slower speed really highlighted the torque increase. Thankfully this time we got the rotor spining perfectly arroun the stator without touching it. So to increase the speed of the motor what we are going to do is to connect all three sets in parallel andd we are going to do that with all three phase. workshop power8 power tools portable saw drill workstation tool box table cel circular press scroll toolmonger battery jigsaw cordless separate Grand L3560 with LA805 loader, EA 55" Wicked Grapple, SBX72 BB, LP 1272 mower. I am buying almost everything online these days so it came from Amazon. Nice work John. You may have to purchase a separate belt if the one we provide does not fit. Excellent! A little overkill on the size of the steel but it was laying around. Question Highly recommended if you have a wood cutting speed press and want to be able to cut metal too without having two machines. It may not display this or other websites correctly. So after drilling more holes, I got everything mounted and wired up everything I could until I mounted it on the drill press. Also, I guess there are cheaper options for the ESC than the one you used? But believe its almost impossible to get it solved otherwise as we dont own a lathe at this moment and the lather workers in our area are going to further ruin this whole unit. Some disassembly and fabrication of mounts and pulleys is definitely required. I placed my order Friday for next day delivery, after the mailing cutoff via Internet. I made a new control panel and mounting box for the FWD/REV switch, ON/OFF switches, speed control potentiometer and a digital tach display. The kit included everything I needed and so far it's perfect. One word of advice i would suggest, i bought a harbor freight 12'' drill press brand new to use this reduction kit on, because it uses metric belts that are slightly smaller than 3/8 i would highly recommend starting off with a drill press with 1/2'' belts as they said on the "tech" portion of the website. Hmmmm, i was unaware of this possibility. We recently brought a drill press and as we have got a limited budget so that one was found from a scrapyard and later repainted. After all the aggravations Ive dealt with through the years with the high speed low torque slowest setting of the machine I was blown away. The outer casing is the hub containing all the magnets and its the rotor. check out the. We made every possible effort to get this thing solved but for the time being the only solution that can help us get through is to grind the rotor!!! Its a very nice product! I might keep this one as my drill press is pretty old and the motor is super loud. The drill press can go forward or reverse. I got the motor for $40 and the rest of the stuff including the cable was about $250. For instance, on a piece I was paying $50.00 for, we are doing the drilling in 1 hour with a jig internally, saving jobs and of course money! Now to drive the drill chuck we need to mount the rotor on top of the main shaft. We were able to pull in the drilling we used to outsource (although we are a little slow). Otherwise, most energy is spent on heating by friction, instead of cutting through the metal. The motor from the hoverboard is a permanent magnet outrunner brushless motor. I am a fan of industrial grade DC motors and varIable speed drives on drill presses. I like how you worked out the problems as you Progressed. A nice problem to have.. I literally just bought an 80's-vintage drill press the same day you started this thread and was already thinking about variable speed control.
