    Question, in pic #4 what are the 3 things in the back row? I can't tell the scale of things in this pic but they look like they might be tool holders that screw on the threads of a P&W spindle? Is...

    E-85 works great for ruining small engines and you don't even have to mix it with anything. Doesn't do most car engines any good either, even if their rated for it.

    This isn't exactly what you asked but here is what I do, since it's hard to get an exact force you will be putting on a part while machining. I go to the Kurt website and look at what force the vice...

    We use 2219 for some of out parts, but I believe -T6 condition. All our parts are roughed out then fully solution heat treated and aged again before finish machining. Of all the aluminums I have...

    Nice link Gary. The PS 95 spindle has the same 33.5 HP spindle that Makino uses in the A51 HMCs. It really tends to stand out amongst its peers.

    I'll speculate here. We use Torlon and Nylatron "plugs" to pressure test parts with. These materials won't scratch our bores. Nylatron is the first choice due to cost but in cases where we blow...

    Most jig borers in good condition should do what you are asking. These guys are correct, you have to test your machine. Some things I would do is finish bore (light pass) a 1" deep hole in alum. with...

    I'm betting you have run neither a jig borer or a Grizzly mill with a Chinese DRO, or you would know that what you say is not true.

    I wasn't sure if "stub arbors" was shop lingo or what Peterson actually called them. This goes back to when we still had KT H-mills in production. Seems like they use Robbjack arbors/cutters for most...

    John, the 2Es had reverse. I wonder when P&W started putting that on the jig borers? Not until the 2Es?

    It does work good for power tapping but the other benefit is you can OD bore with a...
