Mill Brainer:  The Knee Lift

For 50 years now, I’v been cranking the KNEE of hundreds of different milling machines UP & DOWN, DOWN & UP…

Do you guys know you gotta crank the damned thing 160 times to go 16 inches???

 

FINALLY, I had enough!  

I priced out a couple of POWER knee lifts.    $500  to  $1,000!?

 

So, I kept CRANKING...   UP & DOWN, DOWN & UP...

 

Well, here’s the answer!

Normally, we don’t need to take a vertical “cut” that far.  

We just have to get the knee up or down to the working position. 

 

Check out this brainer idea:  Attach a KNEE LIFT adapter to
your portable drill!

Frequently Asked Questions:

  1. My mill knee does not have 9 teeth

  2. What is the Knee Lifter Adapter made from?

  3. What are the mechanical details?

  4. My question still wasn't answered.

Answers:

1.  My mill knee does not have 9 teeth

Contact Ed Holdgate with details about your mill knee layout because we may be able to create a custom knee lift adapter.
 

2.  What is the Knee Lift Adapter made from?

The standard model is made from cold rolled steel, but contact Ed Holdgate to discuss other possible custom materials.
 

3   What are the mechanical details?

Holdgate Enterprises is flexible, so contact Ed Holdgate with any of your questions or requests for custom modifications.    To use the "Standard Knee Lift" your mill crank shaft diameter must be 0.625" (5/8") to fit.  I bored it out to 0.6315" to fit a 16mm shaft (0.6299 also).   The Standard Knee Lift Adapter has 9 slots.   The shank fits any drill chuck that will accept 1/2" or larger drill bit. The Knee Lift Adapter shank is also hex milled to accept a 7/16" socket.   Use then with a Hex Drill Socket Driver (per photo of the Harbor Freight Set).   OAL is 3.124 and Max Diameter is 1.600".    Again, contact Ed Holdgate with questions or inquiries about custom applications.
 

4.  My question still wasn't answered.

Contact Ed Holdgate with your question and a reply within 48 hours can be expected.   If you have already placed an order, please include the order number.

I suggest you count the slots in your milling machines “handle.”   If there are 9 slots, this adaptor should fit just fine!   I’ve checked several different machines and it fits them all.  

The 19.2 Craftsman drill absolutely wings the weight of the knee.   I think a charged-up 12v might work but you would definitely need the socket as the drill chuck won’t open far enough.  

One other thing,

DO NOT USE A HAMMER DRILL.

It’s not good for your machine!

Mill Brainer:  Overhead Clamping

 

This is the FABULOUS OVERHEAD CLAMPING KIT!

 

Squaring plates on a mill can become a cumbersome job – quickly! 

 

This innovative device will allow you to easily and accurately square two edges at once (X & Y).  

 

Use a “table stop”, and then square the other two edges.   Installation of the device is easier than putting a vise on the table.   Once the stop blocks have been adjusted for longitudinal (X axis) parallity using an indicator, the set up can be torn down and reinstalled at will   The device eliminates the need to constantly “move” clamps to machine the ends (Y axis) of parts, and as mentioned, allows the X & Y axis’s to be cut in one setup. 

It utilizes the table stop slot milled into the front of the table on most milling machines.  Check your milling machine for this slot before ordering. 

Various clamping arrangements can be utilized as seen in these photos.  Flip the plate end for end – kitty corner and machine the other two surfaces. 

Use a mill stop at right end.   You will quickly recover the cost of this device in set-up time alone. 

Easily triple your production times!

Mill Brainer:  Quill Device Holder

 

This clamping brainer idea fits on the end of your mill quill, and then you can attach any of your devices right on the end of your quill.  

 

Every once in a while, I really do come up with a good idea.  

 

The last one was in 1950 but I ended up in a foxhole thinking it wasn’t so good after all!


This device is quickly installed and you will find it VERY handy for holding different items like dial indicators and/or spray mist devices. (And cigarette butts can be extinguished in the ¼” hole!)

Three different corner
hole sizes (
1/2  &  3/&  1/4 ) are available

You can re-bore yours larger or
tap them out if necessary.

Fits 3.375" Quill.

Mill Brainer:  Tramming Ring

 

This brainer invention will speed up that tedious mill head tramming operation!

I absolutely HATE screwing around tramming a milling machine head in. 

 

Seems like a completely (but necessary) waste of time!


You gotta pull off the vise (and re-tram it again later…), mess around with indicators, etc., etc., etc.


Try this brainer idea on for size.


(By the way, I recommend you make your own instead of buying one from me….)


Damned material is getting expensive!   Big thick aluminum plate will probably cost around $40. plus.

The tram job is bad enough, but then you have to wipe everything off, reset and re-tram the vise – seems like a gigantic waste of my time and talent(?)!

The bigger the ring is, the more accurate your tram will be. The other advantage is not having to worry about the T-slots in the table bouncing the hell out of your indicator!

Should save you about 30 minutes every time you tram.

By the way, I cut the lightening holes as I was afraid the aluminum plate might warp without the “web” inside it.
Perhaps also the lightening holes would allow the plate to stress-relieve(?) – iffy?

Kinda big but it stores easy and is definitely handy.
