Cool build. I wanted to drop a note that the runout of the tool holder that you made at the end is actually less than 10 microns! Probably closer to 5 microns. This is because you measured with the probe of the indicator at about a 45 degree angle relative to the runout which amplifies the measurement. If you want to learn more about this effect you can look up "test indicator cosine error."

@@artisanmakes you can read my reply above this one for the explanation, but I dont think it actually was a goof...

Work piece rotational speed should be slow compared to the grinding wheel. Doing so improves surface finish, reduces vibration and lengthens the time between wheel dressings. Coolant should either be flood or none at all otherwise thermal distortion can occur (of course depending on part dimensions). As someone else commented (and I agree), reducing the contact area between wheel and part offers huge improvements in surface finish. Hope this helps going forward. Great job, keep up the excellent videos :)

Someone else suggested that too. What I found was that it didn't make much of a difference with soft steel. Low lathe rpm definitely is what is needed for working with hardened steel though

I find your determination extremely impressive. I have a suggestion that might help the rigidity and in turn leave a much better finish from your lathe spindle. The mini lathes use a plastic bearing retainer on the head stock spindle bearings. If you replace them with metal retainers you will be very surprised at the difference in surface finish. Keep up the hard work

I highly recommend an immediate investment in literally any cheap ultrasonic cleaner you can afford. Grinding dust will contaminate each and every part until you’ve given things a thorough wash.

Liked this video because you are using hacksaw to cut the blank... 👍👍

Here's another tip, get yourself an oscillating saw, Milwaukee tools makes their Sawsall. Some fine tooth metal cutting blades for the saw and you can leave your hacksaw for cutting off for old crap . Test indicator notes, bring the needle down to a perpendicular position to the surface that you are trying to measure.

You keep working a hack saw like that and you're gonna look like one of those pro arm wrestlers with one arm bigger than the other. My elbow was aching just watching that.

I have a very similar shop built tool post grinder. I ordered a variety set of those carborundum stones along with some vintage ones on 1/4 inch arbors. I had high expectations, they were cut very well. They did not perform at all well and they're quite a bit Pinker then other carborundum Wheels source elsewhere. I don't think they have nearly as much garnet and that's the biggest problem with surface finish. Try ordering an older wheel off of eBay and see how it goes, I think it might be surprisingly better

We all know that different settings work with different machines because of the cutters being used.

And you've done me (and others) a great favor by showing us a way this can be done.

Never cut stock by hand!

I hadn't noticed first, but you're using the lever indicator wrong. This type of indicator reads how much that leg swings. So it should be positioned in such a way that the part you are indicating pushes against the leg, comparable to the action between a footballers lower leg and the ball. In your current setup, this means the indicator dial should be pointing sideways so that the leg can 'kick' the 'ball' i.e. the endmill sideways. Hope this makes sense...Perhaps look up some videos. The leg should 'kick' the target in the direction you want to indicate. You can always reposition the leg on the indicator - it's intentionally a friction fit. That position is irrelevant. But the leg's position should 'hit' the target 'straight on'. Again: this indicator just measures the swing of the leg. Ah...I finally found a video that clearly explains it: "Indicator Basics - Using a Test Indicator - Haas Automation" (I can't add links in comments apparently) The best visual is about halfway the video - with all the angles.

You'll get tons of cosine error if the probe is that far from parallel to the surface being measured, but it's easy enough to compensate for. Cos(probe angle) * (indicated reading) will give you the actual deflection. Cosine error always increases the indicated reading, exaggerating the deflection and making the runout look worse than it actually is. It's hard to tell the probe angle from the image, but the actual runout on that shank is probably about 5μm. I'd say that's a pretty good result for a cheap Chinese spindle motor on a mini lathe.
