Yeah...sigh. Live and learn. I'm an amateur (and I do mean amateur) and I was running the mill all week in a....less than tidy workspace and amongst the 518 tools I dropped, the Starrett may have...

Here's a new one on me. I've got a set of very nice Starret calipers. I was making some measurements today and I noticed I was seeing numbers real high - roughly 0.02" greater than expected. Upon...

I have a small home brew flood coolant system for my mini-mill. The mill sits in a shallow tub that drains into a bucket. I have a small fish tank pump in the bucket pumping the coolant up through a...

I just checked with paralells too. They do indeed appear flat. But, running the table for the Nth time, the results are the same. <= 0.0005" over the 4-5 inches of travel on the right side of the...

I'm not sure I follow. Assuming, under ideal circumstances that a table is perfectly flat, it shouldn't matter if the slots are parallel to travel direction. The table should be able to move in any...

As I've started delving more into precision work, I've run into some real strange issues with the flatness/alignment of my table.

To start with, I trammed the thing using the standard technique of...

So basically - take it slow on a baby mill :)

....from the perspective of speeds and feeds, that is? Or is it considered free machining?

... I think I generated more questions that the ones I figured out :)

Preface : Beginner, working with a humble Grizzly mini-mill. After tinkering around for a month or two, I built a little...

In my course of learning my way around the mill, I'm trying to figure out the proper way to use basic dial indicators. There are a few places on the web which hint at a tutorial, but they all leave...

In the process of getting my flood cooling system going, I've been milling a few odds and ends using liberal amounts of WD40 as a lubricant/coolant. It works great, but the mess it leaves is....bleh....

In addition to the 3/8" and 1/2" collets that came with my mini-Griz, I ordered a chuck collet set from littlemachineshop

Yet another newbie question. Flipping through the posts here, and reading the textbooks, I always see RPM numbers for milling aluminum that are well above what my Grizzly mini-mill can do. It tops...

They're 1.5" diameter aluminum round stock (I also have 1.25"). What I want to do is make posts out of them about 1.5-2" in length with drilled out centers for bolts. I want to use the posts to raise...

I just realized this should probably be in the General Machining forum. Could an admin move this when they get the chance? Sorry.

(Warning, rookie alert)

I'm looking to make some mounting posts, ala:

I've got my round bar stock sitting...

Thanks for the suggestions.

I've got a spare room inside that I could theoretically convert to a shop, but it's a carpeted room, so....bleh :)

Do you recommend any maintenance/inspection on...

I recently bought a chuck collet set from littlemachineshop. It was basically the same thing as Grizzly offered on their website, but was $10 cheaper and came with 3 more collets.

But when I got...

I've recently picked up a mini-mill and am poking my way through my new hobby. As I've tooled up, I've started wondering how sensitive your average metalworking tools to temperature and humidity...

Ahhh. Yes, I've seen the term bandied about while lurking. Just never put a face to the name, so to speak.

Thanks for the info. Looks like I'm ready to rock, for my meager purposes :)

Side...

Hi everyone. Let me preface this with : I'm a rank beginner, so please excuse terminology or general silliness.

I recently purchased a Grizzly mini-mill and I've started poking around with it to...
