This press has worked like a charm for my projects kzfaq.infoUgkxajoEbapTfqWaadnqb04h6U576yxXp-FE . I didn't even secure it to my table top, mainly due to the fact that I was using a 15 lbs drill vise. It's not flimsy at all as to what others have claimed it to be. Make sure the locking nuts and levers are secured and there won't be any issues with light pressure and patience. I was able to drill through aluminum, plastic, and steel (steel took a while) with no problems at all. Yeah it took a little longer than a regular drill press, but I don't have the space OR the money for one.The instruction manual was worthless, but luckily assembling the press was intuitive. However, the manual would be good for ordering replacement parts if needed. There is a nice breakdown of the parts that are included in the kit. Before ordering, make sure it is compatible with your unit, it is clearly stated what models the press is compatible with.This was an excellent purchase for $40!!

Thank You Lyle.... another GREAT "Wake Me Up" show... I still use a 1940's? Delta on the job. The large table 2 ' 1/2" square 1/2" steel is still untouched with holes drilled into it. A rack & pinion on the column for quick up & down movement. ... Also Lyle the quill is the style that protrudes down from the headstock with the morse taper and drift hole in easy access. .. Ten years ago it was showing slop from the all original headstock and quill. I dismantled, mounted it upside down on the Bridgeport and rebored and sleeved with Aluminum Bronze. Made a new quill and it is the most BEAUTIFUL hardworking drill press I have come to know. .... ( I LOVE all you do Lyle!!!!) ..... TM

I have always remembered, from my high school machine shop class, the little rule of thumb formula for spindle speed, “Cutting speed times four over the diameter”. Along with that, because they were the two materials that we most often used, that mild steel had a ballpark cutting speed of 90 fpm and aluminum, 200. A quick glance at the one chart in your Cleveland book pretty much verifies that formula. Thanks Mr. Don Sarlo, my high school shop teacher from 1971 to 1973 and thanks Mr. Pete, one of my present day shop teachers.

I worked at a fab shop in the 80’s, we had a drill press that was originally belt driven off an overhead drive feeding many machines. It had a 30” table and a 3 speed transmission like a truck might have plus belts for speed changes. It was nothing to drill 2” holes through 3” thick plates.

Keep in mind that speed and feed recommendations are for a production environment. The tooling engineer is looking for a balance between tool cost, metal removal rates, tool life, and downtime to renew cutting tools. The reference materials assume your machine has the horsepower, rigidity, and coolant to get the most out of the cutting tools. In the home shop I usually start at about 60-75% of the recommended speed and feed. I'm rarely in a hurry and longer tool life is more important than how fast I can make chips. Lyle isn't fooling when he says to have your work clamped down and backing for the work when possible. You don't want to have just your hand holding the work when the drill breaks through and the machine's quill backlash allows the drill to be pulled suddenly into the work. You can get away with that with a 3/8" drill, but with a 3/4" drill not so much. Cheers from NC/USA

I have that same drill press and I rigged up a footswitch to a GFCi outlet and another receptacle where one outlet is continuous power and the other is footswitch controlled. I use the continuous for an add on work light and the footswitch control for the drill press motor. Keeps both hands free for the work at hand and I think it is safer as well. Early on in my education I caused a drill press folly where the work spun on the bit. I was ordered to walk away, and others turned off the circuit breaker to stop the drill press safely. Ever since I try to avoid all drilling where the work is not solidly clamped to the table and the clamping is arranged to jam against the column in case it comes loose somehow. This is a case where life presents you with lessons that will be repeated until you learn them. Thanks Lyle for the great videos. I learn something from every one I view.

Mr. Pete: I bought a used Craftsman drill press identical to the one in your video. The base in my opinion was worthless. My neighbor gave me an older Craftsman table saw that he thought might be able to rebuild. It was beyond rebuilding so I disassembled it and saved what I thought was salvageable. I remembered the heavy cast iron table that I had put in the scrap pile. Well, I dug it out and figured out the hole pattern and it came out nicely. It is a big improvement for a base on the press, so if you know if anyone scrapping out their old table saw jump on it. Really like your video's. I've learned a lot from watching them. Keep up the good work! Thanks: Jim Hutchison

While I continue looking for a nice copy to keep near my drill press/lathe, there are clean e-copies to be found online. Like you, my eyes have a hard time with small print, but my e-copy allows me to quickly zoom in and print off (for highlighting) just what I need with the added value of being expendable after getting soaked with cutting oil.

The drill press label stated 1HP Maximum Developed. Marketing to get people to feel the machine power is greater than it actually is. Reminds me of the marketing used by many shop vacuums which state ridiculously high maximum developed numbers. It would be interesting to know how many amps the motor is pulling when the belt slips. As you said the motor looks to be too small to be a real 1HP motor. Dave.

Increasing the rpm would put the belt on a larger pulley thus decreasing belt slippage. The trade off would be a greater load on the motor thus possibly stalling it. It would be interesting to see the difference in time and how much grunt the motor has. Maybe a sequel is in order.? Art from Ohio

Great video Pete; Here is what I did to improve my similar Impco. Make a bracket to bolt down and tension the center pulleys so you can use a 1/2" square drive to tighten the front belt separately. Mount a ball bearing on that bracket for a backside idler near the small pulley on the front belt. Then you can use the present tensioning system for only for the rear which needs less tension. This makes changing speeds a breeze, since you don't need all those fast speeds anyway. Thinking/planning 2 weeks, actual fabrication about an hour. If you like lathe work and have much time you could remake all 3 pulleys making the front larger, the bottom-middle smaller, the top of the middle and motor pulleys multiple step for 1/4 belt.

So I *think* I can visualize that, let’s see if I got it right: - you made a fixed mount for the middle sheave/pulley block. You can still use the step pulleys on that block and the motor to get a (small) range of speeds, using the current tensioner. (My Craftsman moves the motor back to apply tension.) - keep the belt to the front pulley in the slowest position - make an idler with a bearing to get better tension on the front belt to avoid slipping. Makes sense, sounds like something I’d like to try! (But then I have 100 other projects already piled up waiting to be gotten to 😆)

Maybe a set of those cogged gator V belts will keep it from slipping at low speeds. Of course though, having the belt slip might be the only thing that keeps one of your students alive to see another day. Every drill press should have a board behind it with an assortment of clamps made to fit the table and ready to go, no rags, but maybe a small pouch of bandaids handy.

Your drill press is exactly like the JET model we have......great machine.....but I do like my Clausing from a gang drill that I found on a trailer at a friends that was going to the scraper..... As far as figuring drilling speed, I decided to come up with an easy way to figure out by taking a conservative speed and using 300 rpm for mild steel for a 1" bit, then just taking that number '300' and dividing the bit diameter into 300 to get the rpm for any bit size....example would be 300 divided by .250" [1/4"] equals 1200 rpm....works great, and is conservative too.....for aluminum I triple the speed and for austenitic stainless [304] I reduce by 1/2.......only one number to remember!!! 300......I just think of Snoop Dog and his Chrysler 300, not the avocado dip he sells with Martha Stewart,,,,.....never fails, I also use when milling and turning.....I hope this helps some one.....I burned up many endmills, lathe tools and drill bits in my former life......cheers Paul

I have a 20” drill press thats rated for i think 7/8” without even a pilot hole. It was a lucky find that needed a lot of work. It came with a 1.5hp motor and weighs 500lb plus the quill feed has more leverage. It has a drive and I run it a lot slower than that for big bits, 100fpm would smoke like crazy. It’ll feed nice continuous chips chips anytime I see those dusty broken chips I know to feed harder or slow down. That little press put in the effort, at least it tried.

I would replace the V belts, they are old and dried out. New belts have better traction in the pulley. Drills love horsepower, they will take all you can give to a point. To get long life from a bit it needs to cut a full chip, if it slips on the work or chatters it will dull faster. I would always adjust the speed based on the chips, you should get two nice curls. If you get small bits or "needles" you are to fast or not enough feed, and long streamers are too slow. Like most jobs, you'll have it figured out after the last cut... oh, and drilling metal thinner than the depth of the drill point is always awful and often gives poor holes.

For large holes over 1/2 inch I prefer to use hole saws. Safer, as they don't grab, there is less torque required so easy to use on underpowered drill presses or battery or powered hand drills. + I can also usually find something useful to do with the circle I cut out - eg washers, etc. There is a need to use lots of coolant to flush out the chips. For this I use a squirt bottle - water works OK but I prefer a water mix coolant else it causes rust. Or use kero, deisel or WD40 but I'm too cheap for that. Holes deeper than 1/2 inch is about the limit but it's pretty rare I need to drill anything that thick. I use hole saws in the lathe too. You can buy asian carbide hole saws pretty cheap but run them slow if they get hot the teeth fall off. I prefer a set of bimetal type myself.

Thanks for another great video. I just don't understand why manufacturers wouldn't make drill presses that will turn at 100 rpm or so. Even my 1940s Delta (beast) runs more like 250 rpm on its slowest speed. So it has huge castings, large motor, high quality spindle, and yet it wants to burn the cutting edges off of a 1" drill bit (in steel) purely from excess speed. Seems odd to have over-built the structure but not addressed the excess speed. Thanks for continuing to stress these basics that are too often forgotten.

As I've mentioned before I have the very same exact drill press, but it was branded as Central Machinery and I bought it on sale 20 years ago at Harbour Freight. Mine came with a slightly different motor. It's sealed and does use a start capacitor. About a year ago the contacts on the switch welded.. The amp draw on the motor slightly exceeded the contact rating on the switch. Since I had all the parts laying around I changed out the switch for a magnetic motor starter, took off that plastic cover on the front of the Drill press replacing it with small box that fit nicely that holds two industrial type round push buttons. I put in a mushroom red button switch for the stop and a green button for start and I cut out a slot near the bottom for the original small rocker switch that controls internal lightbulb that lights the work. I like it because it's a lot safer. There was plenty of room to mount the small hinged covered box that holds the contactor on the left side of the drill press. I always thought this drill press was a good value.

I have virtually the same drill press. I have cut or sawed 3/4 inch hot rolled steel 5 inch diameter holes with a bi- metal hole saw. Sears claim 1.5 hp. I modified the drill press with a reduction shaft and pully setup copied from a commercially available system. The three to one reduction allows slow enough speeds but still causes belt slippage. Drilling a small hole on the waste side of the part helps chip clearing. At the start if your video I thought you might be going for test to destruction being a Tiawanisium drill press. 😆 lol!

I use a float-lock vise along with a vise-grip type hold-down clamp. I had a 'learning experience' a few years ago where I was lucky not to be too badly injured when a workpiece climbed up the drill bit - ever since then, I've stayed with the belt and suspenders approach. It's safer and it also gives better results.

I am a little jealous, the Craftsman I bought and showed (same model) has a plastic belt guard, and a treaded collar coupling. But the Big Gaurdian ( Large 1hp capacitor start) & the Powermatic 1200 (2 hp 3ph) both have morris taper #3, big plus for my shop. I am looking for my Craftsman a new home, 5 drill press's and a Mill makes a small shop tiny (@@)! I will be on the hunt for some morris taper drill bits, but my 3/4 /19mm chuck seems to hold my large 1in & 1 1/2in with turned down 1/2 shanks well, just can't crowd them. Thx for the tid bits, have a great wk end, Bear

Impressed by the drills performance, although not a top of the range machine,my machine has another set of speeds due to a train of gears between the two main pulleys, it’s a Meddings machine,with a 3/4 HP motor so can drill large holes easily. The use of a lubricant is always a great help!

I’m glad you used your drill press to test these techniques and not mine. Now I know not to attempt them. While my press is fairly new and direct drive I’m sure I would gall the spindle and spend the rest of the year on KZfaq looking for procedures to replace the spindle. That’s why I come here. To absorb your knowledge while I drink a cup of coffee.

Lyle, I prefer the imported TCT carbide hole saws for making large holes. I bought 13 for $26 on eBay, and they are similar to annular cutters, but less expensive. They cut faster than a drill bits, and leave a clean hole.
@beachbums2008
@beachbums2008 Жыл бұрын
Are the hole saws carbon steel or high speed steel? For that cheap of a price,I'm willing to bet there carbon steel,use once or twice then throw them away. Just my $.02 worth coming from a retired machinist of 40+ years experience.

I also use these economy carbide tipped hole saw type drills. Very impressive! I'm also a 50 year + machinist. They work on heavier spindled drill presses. The smaller ones work on smaller spindle drills. Clamp work securely!!! I mostly use these on my Kingston knee mill. Ridgid is key!!!

For large holes in flat stock, a hole saw or annular cutter works better. For cylindrical stock, the lathe is ideal.

Thank you for showing the drill tip so one could see if it was sharpened correctly for it can be sharpened specifically for the job, though I would like to see a clearer picture of the longitudinal relief of the drill. I saw no helix chips a sign the drill might have been a bit dull or need a different sharpening.

I have an import drill press that seems to be modeled pretty much exactly off the Sears drill press you used in the video, it only has a 1/2hp motor if i remember correctly but it is good enough for most work i do. I'd have to check if it has a mt2 spindle, that would be interesting to find out. I never took out the chuck so I'm not too sure. Your drill press seemed to handle drilling such large holes pretty well. I doubt I'd be able to do that with mine. Like you said i usually need to work up by going in 1/4" increments at a time or close to that. Great video as always Mr. Pete.

Did you notice that when you put sufficient pressure for the drill bit to cut into the work that the table deflected downward? I had the same problem with a newer Delta drill press. I made a jack with a length of 1" Acme threaded rod, some pipe, and an Acme wingnut. Bracing the table made a BIG difference. I love my Morse flip book; I call it "My little book of everything I know." I'll have to see if I can find a copy of the Cleveland book.
