The Home Machinist!

No back rake visible in the video.

I use a die grinder to add a chipbreaker.

It's function is clearly to transport and power the apparatus mounted on the right end. No idea what that is, though.

Before you, or anyone without a little experience, can judge that they are achieving good results, they must have something with which to compare. Sticking with any given type of tool does NOT provide that experience. H Thus my plan to start experimenting with insert tooling as soon as I get around...

With DC, there is no fluctuating magnetic field to induce a counter EMF in the heavy wire, so its removal is oper...

One plastic to be careful when machining: PVC. It can off-gas chlorine which will quickly rust any exposed metal surfaces. I always prep the machines by applying a coating of oil for protection. It wipes clean when the job in done. ~RN Machining isn't going to get PVC hot enough to release chlorine.

Sharp micrograin inserts are readily available with chip breakers, positive rake, and included angles down to 30 degrees. I'm looking forward to experimenting with some as soon as I find...

That would have to be a dual voltage delta. Star-delta isn't possible because there's no way to connect it star. See

Part-winding start might be a possibility.

I'm not sure how much threading I'll be doing.. but it is something I want to be able to do. How important is a thread dial? I'm assuming that on machines that dont have one, your only option is not not disengage the half nut while your are threading.... ie.. make a cut... back your tool out, chang...

I would be amazed if there aren't overloads.

The 50 A is reactive current.

I second the star-delta starter suggestion. If that option is unavailable slower fuses have a good chance of working.
