Certainly better than watching Steeler Football on a Sunday. Thanks for the demo. I wish I had one of these when I worked in a small tool and die shop as a teenager.
That was pretty cool, and what made it better was they clearly made it to be regularly taken apart serviced, and easily replaceable parts. Thanks for going as far as you did. It wasn't overly long.
That looks like it uses a standard "DA" collet which was common back in the days for holding drill bits. I quit using them over twenty years ago for the newer "ER" style collets. DA's are still available from a couple of sources out there. As always thanks for sharing, Ken
Very interesting Mr. Pete. Channels like yours and Keith Rucker's help keep the history and knowledge of these old machines and parts alive. Speaking of Keith, he may know where to get some collets for your device. Thank you.
My multi spindle drill press fixture is made by Johnson not Johansson. Mine is designed to drill concentric circular hole patterns. Cam follower slots on the diameter adjusting plate allows rapid circular hole pattern diameter adjustment. It adapts to the drill similar to your Johansson, but has a Morse taper clutch adapter eliminating the need for the drill chuck. Mine was mounted to a very large and heavy Doall geared head drill press. The fancy multi spindle fixture coupled with an integral 3 phase motor meant that I had few bidding competitors and I purchased the machine for $100! I removed the multi spindle drill fixture and installed the appropriate ball bearing Jacobs chuck. Being thrifty I purchased a heavy Powermatic drill press head, stole the chuck and sold the the drill press head making my Doall drill press investment $0! I wish that all investments worked out that well. Our shop used the multi spindle fixtures for production drilling and used drill guide fixtures as you described. I have kept my multi spindle fixture since I haven't found anyone that wants it. I may someday find a need to repurpose one of the small Jacobs chucks it is equipped with. My fixture uses extending splined drive shafts with universal joints to accommodate the varying hole center diameter function. CNC has pretty much obsoleted these fixtures, but they were expensive and highly engineered units in their day. Mine ran multi shift full time production for many years. The drive clutch was badly worn (about 30%) when I disassembled it. Since we never had a requirement to reverse the spindle, this drive lash was not evident in production use. Your video compels me to show my fixture to my son's and grandsons. They probably have never seen such a critter. ...now I need to find where I put it...😊 I call the keyed drive adapter a clutch. That may not be a universal term application, but I have seen the term used by several machine manufacturers for this application. Direct coupled motor/hydraulic pumps on small equipment like scissor lift pallet jacks and snow plows use this drive connection design (C faced motors).
In the late '70's I worked for a small ( about 30 employees) Industrial Woodworking Machinery company. Our bread and butter machines were multi-openng laminating presses for glue-ups, but we also made a drawer front dovetail machine that cut dovetail slots on the back of the drawer front for the drawer sides, with matching dovetails, that slid into the dovetail slots, then a router cut a slot in the back for the drawer bottom to slide into and support the front of the drawer bottom. An option on this machine was an overhead bar/beam that could mount 2 (or more) multiple spindle drill heads (with integral motors) to drill 2 pairs of holes for drawer pulls. These machines could process a drawer front in less than a minute, with repeatable results. 60 machined drawer fronts per hour. I always wondered what the inside of those multiple spindle drill heads looked like, now I know.
What a coincidence that Mr. Pete has demonstrated a twin spindle drilling attachment at the same time that I'm preparing to offer him a dedicated four spindle attachment that uses sun and planet gears. This unit was custom made for a telescope client and drills and taps four 8/32 tapped holes quickly and efficiently. I have no further use for it since my client has sold his business. Mr. Pete has first choice.
I was looking for you to mention the RPM ratio , one large gear and two small gears. Thanks I enjoy all of your videos some times more than once. A retired machinist
if anyone wants to see a BIG version of this look for a NATCO drill, National Automatic Tool Company. Back in the day local big factory had a few of them, even a pair with a shuttle table. They would load a gearbox casting into a fixture, and drill about a dozen 17/32 holes in one shot. Then slide the shuttle over to the other machine where it would tap all the holes at once. They worked well but in production, the little drive shafts and U joint would wear out and need regular repair or replacement. I have had a few Commander heads over the years, came from who knows where. They always had broken gears, the small gears break teeth when abused I am guessing. It was a fun interesting video, Thanks Mr Pete!
Multi spindle drilling is the way to go. They also have multi spindle torque wrenches. Saw one in a Caterpillar movie that torqued all 32 head bolts on an engine at the same time.
Thats a slick drilling attachment, especially for production work, always enjoy you pulling items apart to show how they work. Excellent video Tubalcain.
Excellent video. I have seen these on Craigslist and Marketplace and always wondered how they function. It would be interesting to see the guts of one that had something like six bits. The gearing scenario for six still makes my head spin. Thanks.
I'd never heard of such a device until you featured it in the what is it video. Now I have seen it work and seen what makes it work. I sure got my money's worth on this video! Thank you Mr. Pete, love this sort of thing.
I can see why a small job shop would have a unit like this, one stroke of the quill, two holes, doubles your drilling production. Thanks for the breakdown and explanation Mr. Pete!
I just got dischared from the hospital with pneumonia. That crack about pure bubba and his illegitimate son sent me into coughing spell for ten minutes. i just watch your videos for the comedy
@@mrpete222I experienced a machine when I worked at a furniture and window factory in Garner NC. Was the double end tenon machine. PITA to setup. Cutters Expensive left and right dovetail. In house sharpened and honed on dedicated jigs
so did this company sell different ends for the drill? it seems like it would be very useful in a production line to have two different speeds if you were doing something like using one bit to drill a pilot hole and the other to drill the main hole. or have one hold a drill and the other with a tapping head. I wonder what options it came with
Multi spindle drill models usually have every other drill rotating clockwise and the the ones in between, counter clockwise. That’s why you see drill bits that are left hand. It’s for those multi spindle models.
Thanks, excellent video! I would still like to see what's in those 2 small spindles, as they gotta take a lotta end thrust and look too small for any thing that would last very long on the production floor. The 2 long gears on their fixed shafts is nice, they've got a keyed shoulder & pressed in, the 'cap' as mentioned. Also, did you go by feel for their 1/32 inch mounting spec to your quill?
If you going to throw it out I would be interested in it. I run a nonprofit the makes toy for our local children’s hospital. We do a lot of toy cars that have a through 1/4” axels. Let me know , thanks.
I used to work at a small company making HF antennas (mostly for hams). We had a 3 spindle drill head. Drill press was permanently set up for center drilling various diameters of round stock with a set of vee blocks and the 3 spindle head. It worked fine but was pretty fiddly to set up for our application and to get the holes truly interchangeable (drilling thru both sides of tubing).
I have never seen this double drill attachment. This would work good in a small shop with limited space. And i was in production machining for 25 years.
Jan and I would not have been able to work together because after the first month we would not be able to walk around the shop. I believe you need to pick up at least one time a year😊
I suppose after drilling the first two holes, you could reverse end-for-end one of the bits, and use it as a locator, and drill a line of equidistant holes?
If it is the Johansson that I'm thinking of he was the first maker of slip gauges , I think in America they were called "Jo Blocks ." I'd set them with appropriate "Jo Blocks "😁
I use to run a set up about like that, it had over 12 drill bits in it, we drilled the mounting holes in a large drive ring used in a power takeoff. drilled all of the holes at once but taped them one at a time on a single drill press with a tapping head.
I am so glad you pulled through that Covid and now, improved your tool-auction addiction! LOL...please...no more Redbull! 🤣 Keep the What Is It coming! Yes, we do care!
Certainly better than watching Steeler Football on a Sunday. Thanks for the demo. I wish I had one of these when I worked in a small tool and die shop as a teenager.
Excellent demo, Mr. Pete. Thanks for breaking it down as far as you did. Always interested in how things work.
Great video Lyle. I have always enjoyed taking things apart to see how they work.
That was pretty cool, and what made it better was they clearly made it to be regularly taken apart serviced, and easily replaceable parts. Thanks for going as far as you did. It wasn't overly long.
Shockingly simple,but fascinating non the less. Great video

Those small garage look very delicate. But remember, the capacity of that head is 1/8 inch drills cutting steel.
Did a search for images, big is right, thanks.

Lyle - Good example of a simple - yet elegant - design that 'gets the job done'. And quite a time saver in applicable applications. Have a good day.
Your very last tool auction, Teach? Yeah, right. Thanks for doing what you do, Teach. Most appreciated.
You bet

Thanks for the demo and breakdown Mr. Pete, always interesting to learn how something works.

Kind of reminds me of some photos I have seen from colts Assembly line from the 1870s. drilling and reaming the cylinders of revolvers.
Yes
That looks eminently makeable!
I am shocked by how simple the gearing was , I was expecting it to be planetary gearing much like the speed reduction thingy mr pete refurbished.
I was too

Very interesting video,mrpete.Thank you.
VERY Much appreciated Lyle...
Great Video...

Glad you enjoyed it
Worth mentioning in last example, that middle gear has no impact on the driven spindle speed.
The cavity in which the gears ran appeared to be machined. Was the part a sand casting, and if so how could that have been done?
Brian from Ma great video that attachmint would be good for drilling fixture plate for bridgeport anyhoo Besafe
As Abom79 would say, you could get " two birds stoned at one time" with that attachment!

Great job!
Great for making a cribbage board. Nice sharing the tool.

Thank you for that. My dad told me the same thing 60 years ago, lol.
@@mrpete222 I figured you knew it.
Yes everything is worth taking apart to find out how it works. Some things that are not meant to be taken apart you must use a big hammer. 😊😊

With my luck, I'd break two drill bits at the same time!
Thank you
Pretty neat demonstration. Wondering what the gear-up ratio might be. 2 or 3 to 1?
1 to 2.2
It's on its label.
Thanks Mr Pete 🖖
I suppose after drilling the first two holes, you could reverse end-for-end one of the bits, and use it as a locator, and drill a line of equidistant holes?
You could do that more easily with a DRO on a milling machine. Just move over the desired distance and keep drilling until the material runs out.
Interesting.... Someone will want this!
that's really ham dandy.
I never seen one thanks Mr. Pete
Now we'll have to say: "I need that like I need two holes in the head!"
If it is the Johansson that I'm thinking of he was the first maker of slip gauges , I think in America they were called "Jo Blocks ."

The ultimate tool for the cribbage board maker. I actually have a project that requires 2 holes drilled per piece, can I borrow it?
