I've been thinking about building a powered tool post spindle for a while, for grinding and milling on the lathe. Yours is my favorite design - in particular, the ease with which the belt can be tensioned and the motor swapped out is very appealing. Bravo!

Very nicely done CàLem! The front locknut will influence the runout of the nose even if all the parts are perfect. It is the squareness of the pressure face of the nut and the parallelism of the spacers that causes a deflection of the nose. By lapping the pressure face of the nut to remove material at the low point of tir when measuring on the OD of the nose you can get the nose to run true. You need to keep the nut face flat while altering the angle of the face. Also as you remove material from the nut face the tightened nut position keeps changing. This makes the process very difficult and tedious but is a skill that experienced spindle rebuilders must master. ATB, Uncle Robin

Thanks unlce Robin I did notice that on your mill bearings repalcing. Never tried lapping before. Definitely will get some compounds and mess around soon 🤓

Hello gentlemen, can the problem also be caused by the type of collet used? When tightening on this type of collet, you keep the diameter on one end as it is, while diminishing it at the slotted end. The taper consequently will vary, the more so when you have to tighten more. I would prefer ER collets for this reason. They have their slots alternatingly running front to back and back to front, so the taper is more likely to remain constant and will settle against the receiving taper in your arbor even if either is a minute of angle out of spec. Have a nice day!

One of my tenants has a bunch of CNC's in his shop. Not one person in the shop can run a manual mill. They're more computer programmers than machinists if you ask me. They still make quality parts, but how they get to those parts is a completely different world. I'm not sure they could make anything by hand. At the same time though they can make parts far more complicated than any manual Machinist could dream of.

Great skill, as always. I suggest building guards for the stone and the belt. At those speeds, a face shield might not be enough in the case of serious failure. And having a piece of the stone embedding itself in a hand/arm/chest or getting a whip from a belt thread is not much fun, either. If you want to use induction motors (like the two you tried first) you'll need to use a VFD, otherwise you're limited to the mains frequency, i.e. 3000 rpm for 50 Hz. Using pulleys would to increase speed reduces torque, requiring an impractically large motor. Regular 50 Hz induction motors usually work fine at 100 Hz (I use this setup on my mill).

The best way to protect yourself is to ensure that, as much as possible, you keep your body and anything else important out of the plane of rotation of the grinder. I always keep myself as far as possible out of the plane of rotation when I am using any rotating machine. Personal protective equipment is important, but it is in the third level of safety, first level, is a safe workplace, this includes the machine itself, ingress and egress routes, correct unobstructed working space, machine maintenance, etc. The second level is proper training, and the third level includes personal protective equipment and "magic". Magic is things you can't see but can only assume are working, this includes things like stop-saws, earth leakage breakers (core balance devices, and the myriad of other names that have been used for earth leakage breakers) - WARNING these only protect you if you are connected to earth, if you are insulated from earth and become a load across a high voltage circuit, the breaker will not trip and you will be toast. It is amazing how many people seem to not know this serious issue.

The spindle was so great. Amazing publish. The studies that you made about the spindle was very fine. I don't wanna be boring but, in my opinion, I do believe you can put less speed on the milling process. The motor could be assembled on the shaft by helicoidal gears. This device is amazing, don't through away. Perseverance my friend.

I built a really simple holder for a airdriven 20€ grinder to grid some chucks. Worked well. The only problem was the massive air consumption, which lead to a noticable change in rpm and believe it or not, in grinding disc diameter. I had to ensure that the final pass was always done with a full tank of air or it would not cut material after the previous cuts.
