I thought it was high time we started a Delta Manufacturing Co. / Delta Rockwell thread to discuss and post all your Delta/Delta Rockwell stuff.

"Delta Specialty Company" was started in 1919 by machinist Herbert Tautz while working out of his garage, initially only producing small home tools then growing to light industrial. In 1929 Delta Specialty Co. became Delta Manufacturing Co.

In 1939 Tautz sold the company to The Marshall Fields Company, and in 1942 Marshal Fields sold the company to the Timken Detroit Axle Company.

Finally, (for purposes of our thread) in 1945 Delta was purchased by the Rockwell Manufacturing Company of Pittsburgh, Pennsylvania.

Rockwell continued with the Delta Milwaukee badge, but began incorporating the Rockwell logo on the serial number/model number tags. When Delta workers went on strike in 1952, Colonel Rockwell closed shop and moved production to Ohio and Mississippi. Badges then became Delta / Rockwell, dropping the Milwaukee.

To start this party, I'd like to submit my 1937 Delta belt sander, which I will be painting the original 1930s Delta gray / green when I know I'll have a week or so of decent weather:

Here is the original Delta grey / green. I think it's awesome.

86511.jpeg

I lucked out in that this belt sander came with very uncommon Delta cast iron wheels / foot pads. 8 pounds of wheels!

86510.jpeg

Here is a part I tracked down on a second Delta BS, the vacuum attachment.

86450.jpeg

And yet on a third, red Delta BS I snagged this "era correct" cast iron pulley guard. Comes in at 35 pounds!

All right gentlemen, let's see your Delta MILWAUKEE table saw, drill press, band saw, shaper, jointer, scroll saw, disc sander, belt sander, grinder, etc! Date your machine as best as possible as Delta went through FIVE badge / logo changes from 1936-52!!

Okay, I’m in! Here’s my 1947 Delta Milwaukee 10” tilt top table saw. The saw is in original factory condition. Next is my 1954 12” disc sander. I bought it from its original owner and fully restored it a few years ago. Although the serial number is from 1954, the badge on the front edge of the table still says Delta Milwaukee. Next is a 1951 17” drill press that I restored. The head badge was faded to nothing so I tried to find a better example. I ended up finding a pretty good next generation badge. I’m still looking for a correct badge if anyone has a spare. The motor badge is correct. Last is my 1952 HD shaper in original factory condition. Oh yeah, and my 1948 Unisaw waiting to be restored.

I've had too many Delta Milwaukee machines to count and found them all solid and mostly well engineered. One may take issue with the table trunions on the bandsaws being weak, and using a proprietary bearing on the 14" DPs, but there are few flaws in these machines.

Delta was responsible for many industry firsts and innovative ideas. What may be Deltas most renowned machine is the famous Unisaw table saw. Making it's debut in the 1939 Delta catalog, the Unisaw was the first 10" cabinet saw to offer a tilting arbor, and at 83 years, is by far the longest production line of table saw from any American manufacturer, and one of the most widely distributed machines ever produced. In 1939 the Unisaw cost roughly $168 (depending on set up), that is $3,359 in 2022.

And here it is, as it first appeared in 1939 with that magnificent art deco styling and lettering:

Screenshot_20211231-085034~2.png

Delta devoted several pages of their catalog to tout all the new features of the Unisaw:

Let's see those beautiful Delta Milwaukee machines!

Here is my Delta 17, other than a standard rebuild I added a VFD, custom mobile base, custom vfd mount, wood working table, and a fixture plate for metal work. I also re built a delta table saw but I'll post that separate.

This is a late model Delta 5hp 12-14 table saw. I built a custom mobile base with leveling feet. Used a vfd to power the 3 phase motor and provide soft start. Every nut and bolt was cleaned or replaced. Any holes not used on the cabinet where welded up for a clean look. It's heavy but rolls like a dream. Last photo is a delta four footed shaper I'm currently working on.

Thanks, it's been a lot of fun so far. The table saw is my favorite as of now. I think because it was a immense amount of work and even had a member machine me some missing parts!
Pretty good sized workshop at well. Thank you for those outstanding additions.

As famous as the Unisaw is, the 14" Delta band saw may be even more so. Endlessly copied, the Model 890 came out in 1934 and remained largely unchanged for well over 80+ years until Delta recently adopted a modern square style bandsaw.

Almost everyone has either owned or been in a workshop or garage at one point that had a Delta 14" bandsaw in it.

Here is how it debuted in the 1934 catalog, with Delta dedicating 3 pages to hype the advantages. Note that it came with pressed steel wheels, had raised indentations on the wheel covers, used an open back design and had steel knobs. Delta didn't have a badge in 1934, most machines just had the name Delta cast onto the frame, or had a decal of an unfurled parchment with "Delta quality tools" within:

Screenshot_20211231-202419~2.png

Screenshot_20211231-202428~2.png

Screenshot_20211231-202436~2.png

In 1937, Delta made several improvements to the Model 890, the most obvious is the smooth, graceful curved wheel covers we are all familiar with. Delta also brought forward the controls on the lower trunnion, and introduced the belt guard accessory - a 30 pound cast iron beast!

Screenshot_20211231-210204~2.png

Screenshot_20211231-210212~2.png

In 1940 the pressed steel wheels were replaced with cast iron, and in 1941 the gloves came off and Delta introduced the cast iron pedestal.

Screenshot_20211231-211210~2.png

During WWII other changes took place, the cast iron wheels gave way to aluminum, and the belt guard became stamped steel, yet the basic style, form and function remained.

Here is a Delta trio, all three are dated 1950. This was a probate sale and I paid $200 for the 220, scroll saw and shaper. Person handling the sale picked up the tenon jig and said, "I think this goes with the shaper" I didn't argue and was just handed the jig. Picture is as I found them.

Love my triple duty grinder, my first real pedestal. I'll have to get some pics of my other Delta machinery. The right tool rest has been replaced with the proper vintage. I might give it a paint job someday. I use the top switch for the lights and the pedestal switch for the grinder. Truly a rare find in CO.

Ok, I did find a couple pics of my sander. This is a later model, but I replaced all of the worn 6x48 parts with a nice 1950s model I found. It was a tough decision but I did not want to lose the disk sander and the 6x48 parts were well used. Also put in a craftsman articulating lamp and the c-h switch. These are great sanders no matter what year you end up with. I do need to find a dust port for the disk sander at some point.

I'll play. A 14-inch metal/wood bandsaw dated 1954 (same as ME). I made my own fence for it. No other pics as I sold it last year.
Exmaxima, is that a Walker Turner hand wheel attached to the upper wheel guide assembly lol? Nicely done.

Here is a 1938 Delta DP220 that I posted last summer - but it gets a curtain call for this Delta Milwaukee thread. There was much discussion as to whether or not the jack shaft assembly was made by Delta or not. This question is still unresolved and may never be figured out. The "Model 14-207" which went by DP220 because of the head casting number, had a very long production run with Delta.

86494 (1).jpeg

86699.jpeg

When this lever is forward as shown, the belts are tight. When the lever is released and rotated back, all the tension is released making belt changes quite easy.

86705.jpeg

Here the lever is back and you can see all the tension is out of the belt, with the two motor mount plates separated.

86702.jpeg

Here is a picture that GJ member @BradnCali found in a Delta catalog that shows the exact jack shaft assembly being used in manufacturing, most likely during WWII with a woman manning the drill press.

Screenshot_20220102-175741~2.png

And here is one of the greatest badges ever created.

Regarding the 1934 introduction of the Delta 14" bandsaw, I want to offer this outstanding example. Not only is this a very early, possible first year bandsaw from Delta, but this 85+ year old gem has all it's original paint and decal. I received permission from the owner to display these photos. He uses is almost daily and said the PO took great care of it.

15576-B.jpg

I have personally never seen an early model Delta bandsaw in the wild with the open frame and Delta name cast into the upper wheel arm. Note also it has a ball crank handle on the upper wheel guide assembly instead of the star knob.

15576-C.jpg

Note the red angle gauge takes up the entire trunnion, and that Delta name there looks great. Trunnion uses full length solid flange instead of the much smaller "three arm" design.

Here is my first Delta 220, a 1941 (the mobile cart was very temporary). Technically it is a model 14-207; each 14" Delta depending on how it was ordered had a unique designation -at least six different variations. Therefore, we call them all 220s, much simpler.

88175.jpeg

88170.jpeg

88200.jpeg

Here is how it looked when I brought it home:

88232.jpeg

When I removed the Delta badge from the front pulley guard, this was the original color. Rust-Oleum satin charcoal gray is an absolute dead ringer. Delta has changed their shades of gray many times, the repulsion motor was painted with Ace hardware Machinery gray.

The attached pics are some of my Delta tool collection, at least one of which (the disk sander) is dated 1945. I still use them frequently, except for the D.P. which needs some spindle bearings. I inherited all of them from my dad. I was born in 1955 and these tools are among my earliest memories of my dad and his shop. The disc sander I recently "refreshed" when the bearings started to growl. The drill press is starting to do the same thing, so that will probably be my next project.

I also have a 12in x48in Delta wood lathe, and Delta 10in radial arm saw of similar vintage. Will post pics later.

Great refresh on that disc sander! What color did you go with?

I took an original piece from the sander that looked like it had suffered the least "aging" down to the Sherwin Williams store. They scanned it and came up with the "recipe" for a color. Don't know how accurate it is. I specified that I wanted an industrial grade brush-on paint and went with their recommendations for the gray and black.

The paint didn't "flow" as much as I would've liked, brush strokes and runs are apparent if you look close. Next time I might go with a premium rattle can.

Don't like painting. I appreciate a good paint job, but I don't have a talent (or patience) for it.

Hey jmarkwolf,

I‘ve gotten some pretty good results with this stuff. I used it on my 12” disc sander depicted above in an earlier post, and my restorations look almost as good as Hoorn’s restorations.

I previously showed this 1937 belt sander:

Screenshot_20220124-200619~2.png

I took the side panel off and brought it to my local ace hardware to get a quart of Benjamin Moore color matched. This is what the paint guy came up with for the original grey-green. I think it's dead on.

PXL_20220125_035501155~2.jpg

If anyone is interested in the original 1930s Delta grey-green, here is the color code.

PXL_20220125_035511974.jpg

I would have preferred oil based paint, but for those who don't know, we can't get that anymore in California.

Be aware brother man that you could get banned for a week over something that seems trivial to you. Aside from that, you have done a great job restoring that machine, and because of you it live again.

@Nutria that is an outstanding scroll saw. Love the Craftsman Powr Panl addition. I don't think I've ever seen a Delta motor badge like that one, thank you for posting it.

It's been awhile since I acquired and overhauled the machine, but I estimated a 1942 birth date at the time, based on serial number I think. Of course, the motor could have been a later addition.

This is my only other relevant machine: 6" short-bed jointer, late 1930s, I believe. Found in a junkyard on an original combo table that lacked the table saw. It fired up right in the yard, despite what turned out to be about five gallons of sawdust in the motor. The no. 1120 RI dual shaft motor did not have a shaft cover as an option; I think that those appeared just two-three years later. So this one got a Pinnocchio nose from a towel rod bracket. The machine is a pleasure to use.

Nutria you have some fantastic Delta equipment. Looks like original paint on the jointer and on the pulley guard too; that thing was very well maintained. That three line Delta badge you have indicates it was made between 1939-41.

Those big 8.5" diameter RI motors are the best. I have two 820 1/2 HP RI's and a 1 HP 84-940 that spins at 1425 RPM. Torque!! Thanks for sharing.

Yes, thanks, original paint on the machine and motor-- not on the stand, of course. Agreed on the old Delta RI motors; they sure do punch above their weight.

And thanks for narrowing down the date for me. I forgot that there *is* a serial number on this one: 13-527, which should make it 1941, consistent with your call on the badge.

Hey jmarkwolf,

I‘ve gotten some pretty good results with this stuff. I used it on my 12” disc sander depicted above in an earlier post, and my restorations look almost as good as Hoorn’s restorations.

Hi Jim

I'm about to start painting my drill press. Is the Rustoleum you suggest durable and scratch resistant?
