Default Various experiments with an old metall mill

This little adventure started around a year ago so I'll try to do a write up of my adventures with this, hopefully someone finds it an interesting read!
Do people prefer images attached as clickable thumbs or big size? Not sure what is proper forum etiquette.


I've always wanted a metal mill so when this 1947 K&T 2HL showed up for aprox. $600 I went and picked it up as fast as possible.
Weighing in at around 2600 pounds it's a bit of a handful for someone with no real equipment. The seller helped us load it up on the trailer I had borrowed.

Had a friendly contractor working in the area help me lift it off the trailer with his digger but getting it the rest of the way into the garage was a bit of an adventure..
Drove our little golf in and attached a chainblock to try and pull it in, which often resulted in the car moving rather than the mill...

Eventually managed by very carefully hoisting the rear up and letting the jack act as a dolly of sorts ontop of some scrap plate.

What followed was what felt like an eternity of cleaning to get rid of old grime, loosening seized components and just generally trying to understand my first ever milling machine.

Here it sits after I got some tooling for it.

And here's my first "real" project with it. I had done some tiny milling before but here I milled out all the "teeth" on the bottom thing and milling a bunch of other stuff to square and size.
The whole thing is a manual splitter for firewood
Sure, you could do this with an angle grinder but where's the fun in that?

After using it for a while I decided to do a small teardown since I was constantly worrying how the ways and oiling systems looked underneath.
It is after all 72 years old.

On top of the knee ways you have a saddle for Y movement and also Z axis rotation(ie the entire X table can rotate).

This is one of the nicer looking parts... Lots of sludge to remove and the oilwicks were .. Let's say they had passed their "best before" date.

Here's the little X screw, mid-cleanup.

I also started going through the vertical head that would every now and then let out black goo through the spindle bottom..
It was filled to the absolute brim with grease, most of it looking to be from the early 1800's(Ok, maybe not that old)
I took a whole lot of fistfulls of grease out of it...

Here's almost all the parts that go into the vertical head attachment, cleaned up and nice. Most things still in good shape.

Whole machine is starting to look a lot better, besides the worn paint.
I have also started installing a DRO here.

For some reason this picture uploads rotated.
With a decent working matt it was a pleasure to play around here.

Based on my own experience I can tell you that having a milling machine that is old and clapped out is a lot better than having mo milling machine.

Looks like a fun toy!

Welcome to the site. We need fresh meat

That's an interesting configuration, never seen a head like that. How is the accuracy and rigidity?
I will say for never owning a mill before, you did take on quite a project, but from what I see, it seems to be in great shape for it's age.

Be sure to lock your wallet up when you are near the mill, they have a magnetic attraction for money.

Walker:
I was originally looking at import milling machines which would've underperformed this by a lot despite costing 4x as much. Needless to say I'm secretely in love with this old piece of cast iron.
There's just something about old machines..

Ironman:
It's a lovely head for doing weird angles BUT I do imagine a regular head would've been much stronger.
I can run a 160mm carbide insert facemill without too much problems but only if I use half the inserts(4 out of 8) otherwise tool pressure becomes too high, or that's my guess anyway.
Accuracy wise I can get it within a few thou usually, I feel any lack of precision is more my fault than the machines.
I can assure you my wallet has already filed for divorce.


Sometime around here I made a bad mistake as I was testing out the overtravel stops...
One didn't work.
When it was supposed to trip and turn the powerfeed off, it instead jammed and caused the entire powerfeed gearbox to bind up and shatter the weakest link...
This is the input gear to the entire knee gearbox, controlling all feeds except rapid traverse.

Here's the powerfeed gearbox taken out, quite the procedure.
The above gear sits on the backside of this.

I did my best to repair my mistake but without the proper tools and knowledge, it never became 100% good. However it did run decently for quite a few weeks, probably closing in on 80h of actual work.

During those 80h I managed to finish my DRO install, just a "cheap" asian import DRO but works well enough for an hobbyist amateur.

All the brackets cleaned up and painted.
I'm big into re-using materials. Most of what I've used here is scrap that was going to be thrown away or had already been discarded.
Feels good to not let more stuff go to landfill and also tends to be cheaper.

The attached pics at the bottom of the post do just fine. No need to double post pics. Nice looking machine.

You're on the right track by using thumbnails and uploading to our server rather than using offsite hosting. However, there is no need to display them twice. You can position them inside your text if that suits you or simply let them string across the bottom. We're used to both practices.
What we do not do is use the IMG tags to paste full size photos into the page as embedded images from Photoshop, et. al. Takes too long for them to load even with today's connection speeds and offsite hosting usually results in ruined threads when the users eventually edit their hosting services.

Welcome to SFT and congratulations on your ambitious thread.
As Ironman said, we do need fresh blood and some raw meat on the grill.

I'd add to that by saying that the Machining forum would be ideal for this thread.

milomilo: Apologies, I'm not too proficient with this kind of uploading!
cutter: Thanks and apologies! I like to have them stringed into the text as it makes it easier to follow along to what I'm trying to describe. But how do I get rid of the thumbnails at the bottom if I do as such?

Currently I add them to my text with this:
[ url=url to fullsize picture][ img]url to thumbnail[/ img][/ url]

How do I add them to my text so it doesn't also display them at the bottom row?

Ironman: I will report the thread and ask a moderator to move it.
