Went with the C330, I'm partially brand-loyal to Niagara after using one of their 1" 5 flute HSS hog mills. It should be in by next week, so we'll see. Sending one sample case out to treehugger so he can torture it in his truck, then waiting for the 3 flute endmill to make it's way through the ...

I'm mostly set on a Niagara C330 TINI coated 3 flute. There's also the Precision Twist E3603G 60 deg, but it's 5/8" flute length, which might counteract the entire reason for going 3 flute to begin with. Then again, I catch myself doing blind bore operations up to the full depth with the 2 flut...

2 flute, non-coated, relieved. I'm looking for a 3 flute in the catalog as well, possibly TINI coated with a larger shank so I can put it in a solid holder instead of a collet.

I've got walnut shells in a vibratory right now, mainly for knocking off the small burrs. Usually I can get away with 12K on the spindle and 24IPM feed for 1/8" carbide, but I'm thinking I'll have to halve that due to the resonance issues with. I'll also be switching the entire shebang over to ...

Got one finished today, should be close to the final design... damn chatter is STILL there, even after dropping feed and speed... Looks like I'm swapping everything over to conventional from climb... http://zarnochwf1.com/gallery2/d/3707-1/IMG_20110711_144302.jpg The bearing bores are .0005" ov...

Yeah, that's the joke!

I'll try and shoot a vid, but my phone doesn't like taking video...

Work of art???!!! THAT THING??!?!?!

Someone hasn't felt the horrendous chatter marks that come from jacking up the feed rates that high!

You're $1100 off John, it's more like a $400 truck...

Weight comes in at 34 grams without the dowels, 35.4ish with them. I'll ...

From an outside perspective, I prefer powerpole connectors to the deans connectors.

Much less chance of an inadvertant short, and a more positive lock.

Back to the grind tomorrow (today?), here's to having everything bug free!

Yeah, it was only a small change on the solid model, but the toolpath generation required a full redo to compensate...

We're a long way from "make the solid, get the part with optimized toolpaths!"

Haha, yeah, I ended up getting bogged down in the CAM side of things, ended up being a bit more of a PITA than I expected.

Then I found an error in the model, so that was "yep, time to redo all of this...".

Have a happy 4th everyone!

Well, I'm not going to hit my "by the end of the week" goal.

I hate to see what the bearings look like after a toothpaste treatment!

Then again, they would be "minty fresh".
