ok. so ive seen a bunch of people complaining about the backlash on the x and y. the big mills have backlash too. what you want to is either move it x+ or x- right up to your correct dimension. and if you're right up on it and you stopped before you got there and theres backlash you need to go in the opposite direction and then re-approach it and stop exactly on your mark. and then it will be accurate. thats how the backlash works. reference, i'm a mechanical/electrical engineer in an r&d department that uses cnc mills and regular knee mills. (bridgeport, grizzly, and WEN) bout every day. and i also have a heavy background in welding/metal fabrication/ machining/ cnc operation and programming. before i became an engineer. then you really need your vise properly indexed. it just helps keep your part square if you can get stock with square sides from the steel mill

This drill and mill is very versatile for general machining. Like the way you reverse mount the hex bolt for machining. Saw a bit of vibration of the spindle frame during a drilling process. You can reinforce it by adding some machined parts.

Hold the bolt farther up in the collet for less stickout. This will increase rigidity and achieve as better cut. Also try using a steel v block instead of a soft jaw, for the same reason. Rigidity. Otherwise have fun.

Boring bar as a tool holder? Well, it does hold a cutting tool, so why not? He says that what he demonstrated was what a boring bar was used for (31:04 - "That is how that tool is used". But that is one way to do some turning in a pinch if no lathe is available. Nice honest assessment of the milling machine and related tools, clamps, etc. one might need.

When you were using the face mill the first and third pass you were feeding the material the wrong direction. On a manual you should feed the material so the cutter is trying to push the material away from it.The backlash could jerk the material in and break your inserts.
@turbocobra

So do you reverse spindle direction on each pass ?
@BigJsgarage

No, The spindle has to spin clockwise for that tool. you would feed the material from the left side of cutter on all three passes like you did on second pass.I guess the best to help you understand is google climb cutting and conventional cutting.

Also there's Enco tools, but I've never bought anything from them, so no comment on them. Supporting the ends of the plate you were facemilling with machinist's jack may help with the chatter.

As you might have figured out by now, you're running far too high RPM's. Lower RPM's will take out a lot of the chatter, and your inserts will last longer too. So, slow down there, Speed Demon! (p.s. as someone else mentioned , clamping straight to the table would most likely work a little better. just start with all the clamps on one side, mill the other, when you're done, just move the clamps over to the finished side, one at a time, then finish the side that was under the clamps. easy.)

Even though we have known Christ according to the flesh, yet now we know Him thus no longer. 17 Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 18 Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, 19 that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. 20 Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. 21 For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. 2 Corinthians 5:14-21
