Hey All, Newbie here again ;) So I have a typical round column mill. Just like the King PDM-30 but from Modern. Anyhow. It started to make a loud knocking noise and it looks like the pulley stack on the motor shaft is now kaput. I wanted to look at all my options. I might be able to bore it...

Yes. This is the way I look at it. I just don’t know where to start in order to evaluate the chip :) Seems like a lot of trial and error.

I have the formulas I dont have the proper SFM per material for carbide inserts. ( https://littlemachineshop.com/reference/cuttingspeeds.php is the best chart so far.... but that says its for turning, not milling. The milling chart doesnt offer carbide)

Thanks for the info. I have heard and understand a good portion of that. (So if I have this correct you are saying use a HSS guide and X2 to start?) Let me reword my question. "Cutting speed can very for carbide from 500 to 1000 depending on coatings and material it(s) used on" How the...

Im having an issue here. Every time I think I have the right cutting speed figured out I bounce the number off of my machinist buddy and he laughs saying "that is way to fast" or"Way to slow". Now it is easy enough to find a chart of cutting speeds for HSS. (Milling operation) But, I am told...

This is what I think I know :) Hope this help add to the understanding on it - Amperage is what makes breakers trip. - An electric motor will fight to stay at speed. Meaning the more you slow the shaft, the more amp it will eat trying to get back up to speed - An electric motor can draw up to...

well at this exact second.... I got 320$ for it :) I can only work a little bit once a week to go into this pot. Rest of my free time (which is limited) is reserved for my family. So it would be nice, but still cant do it yet. Will advise when I am closer to my goal value then we can start...

I’m gonna working my way to save up 3k. Hoping I can get something like a used king 1236. Going to take me a while though. But at least that tells you guys what I’m setting my goals to.

Those links didnt work. But to be honest at this moment in time, there is no money to go into it. Or at least very little. I am working a second job with a blacksmith to get some extra coin, but I can only work 1 day a week with him as the rest of my time is my normal job and my family. As soon...
