pretty much everything Keith said, knowing when to use a yardstick (meterstick?) and when to use a micrometer is a real deal, more precision than you need is time not well spent

For gimpyrobb.
Here are pictures of a couple of drills I made from busted mills. The guy told me to grind a spade tip and negative cutting edge so it would be strong. He said you should run them fast and feed lightly, and it will drill through a tap or any other broken tool.
I have 3 carbide twist drills but I would never use them in a hand held drill because it would be so easy to destroy a $100 bit. These things would function best in a mill or drill press, but if I have to I would use them in a hand drill as they are already paid for and their life was over.

Makes sense to repurpose then if you can. Looks good Gerry.

This old Tony" on you tube took the opposite end of a broken carbide end mill and turned it into a 20 degrees chamfer tool. The results were good. I think I've watched all of his machining related Videos already.

Yesterday I dropped a new 3/4" end mill on the floor and it broke in half I have it happen to drill bits to, it seems that if they land flat they will brake. Same thing with a good pry bar.

Ordered so far:
123 blocks
Machinist square set
Protractor
Edge finder
Parallels
4" vise - HFS brand https://www.amazon.com/HFS-Milling-M.../dp/B00KRRBROE

Ordered the 4inch vise today. Immediately after that someone local offered me a 6 inch Kurt for $400. I might have to go check that out yet but that's pretty big for this machine. They are on ebay for $350 to $600.

just the start
you will need an Indicator so you can square in the vise and something to hold the indicator...................

I just grab a piece o round stock in a collet and use the mill to get the vice true to the axis. A DRO helps but is not necessary. Work that is directly clamped to the table can be trued the same way if you are putting a feature in with respect to an edge. if the feature is not true to an edge more creative methods are needed to match the individual job.
Tramming the mill before you start using it is probably the most important thing as proper tram affects finish quality and accuracy as well as tool life.

With a mill, words to live by.

I cannot remember for sure, but I think it was "Old Man" that turned me on to using a new brake rotor for getting a good look at leveling things on my mill. Of course should I need a rotor for my 94 ToyPup, I'll have to get another for the shop.

The vise looks good. The brand is HFS.

Got a quill indicator holder and a cheapy half thou indicator. Looks like its about .003 out of tram across the vise. Will get that dealt with in time.

Now I just need a project!

My first vise was the same (at last it looks). I did not have a problem with it for a long time but I got a real Kurt. Anyway, I modified mine according to this guys mod:

Mine was the same way, small dia. on the shaft. I welded up and turned the same way luckily before the thing got whacked. It's worth wile to check before you get cranking on it.
