The "Ask Nathan a Question" Thread

We have Makino graphite mills in the other building that we use for scales production and they use a lot of air.

We have a small Atlas Copco rotary screw compressor as our primary air compressor with a relatively low output Quincy reciprocating compressor as the backup. Being a reciprocating compressor that Quincy is not rated to run 100% duty cycle and it has been tricky getting the Atlas copco pressure settings high enough to prevent the Quincy from running constantly. Setting the pressure on the Quincy lower creates a low pressure situation in the shop so that's not an option.

So I picked up a larger Kaeser air compressor at auction a few months ago. Chris and I pulled the Quincy out and put the Kaeser in there as the primary. Well, unfortunately, it's causing some electrical issues. It's twice as powerful and that big motor going directly to line is dropping our wild leg of the delta three phase out of range which is making the CNC machine tools alarm out. So we can't run it until I fix the power problem. Which I'm in the process of trying to do with an enormous Liebert Npower system that I bought from General Motors that they were using in their engine building plant in Tennessee. They were having some issues with it so they replaced it with a new system however Chris and I were able to debug this one and I have a new board on order so hopefully we can get that going so we can get both compressors (and the little DMGs that need the neutral from WYE three phase) going so that we can get all 10 machine tools online.

However I'm the only one that can actually do the finish sharpening on the fat bastards. So I'm spread a little thin right now.

Good Lord man. I really need to fix my driveway.

Sounds like you have it all under control. Great work!
 
Hey Nathan,

I’ve got some of your Diamond Schmoo on the way, which I’m excited to try out. Is there a best method for using it? Spray on the flesh side of a strop and then finish on bare leather? Or is Schmoo the final step?

Thanks — I’m grateful for any insight.

Schmoo final step

Don't spread it out leave it as a mist. The droplets behave like a structured abrasive

When the bottle clogs up, make a little voodoo doll of a fat little white guy with a gray ponytail and poke it with your sabenza

With good technique, a LC will be fine. If you're snake slapping it, you can expect some bent primaries. People like Jo, Ben, Sue and Dan can run these really hard and have no problems but I have to focus. I have a bent primary on my own Light Behemoth. I'm hard on stuff. 😞

I like the LC in the woods because I can arrest swings without hurting my wrist, and it really does hit above its weight, but the SC is a more capable tool and the weight difference on your belt is not noticeable.

The Light Chopper is a carbon copy of the old Medium Chopper profile. The 10" Standard Chopper has been tweaked a hair to add a little bit more weight to the tip. It will have a tiny bit more power than the original MC at the expense of being slightly less flickable in a snap cut. Most people would never notice a difference. I think it will be the best general purpose 10" Chopper out there with an unmatched combination of cutting capability, durability and edge retention. It would be competitive in a blade sports event and you're unlikely to tear it up in rough use. If you liked the old MC, I think you're going to like the SC about the same. The MC was one of the best CPK we ever produced and I'm confident the SC will be viewed the same.

I would take the LC on a camping trip. It is an outstanding option for a large Camp knife that can do double duty with meal prep. I would take the SC into the woods in your line of work, it's the more capable tool.

Perfect exactly the info I was hunting for. SC/MC will be on my hit list once they start to circulate!

No, but I am considering a very basic lockback just to get some Delta 3V in my pocket.

I really need to do that. Right now I can't find my Shiro (it's lost again) so I'm carrying something in m390 that I won't name that has the worst edge retention I have experienced in a while. Pissing me off and that folder gets closer every time I use it.

A lot of us would definitely like a folder with Delta 3V, too, but I am wondering why you don’t pocket carry one of your EDC knives? A pocket fixed blade can be useful.

Also, what happened to the CPK Encyclopedia sticky thread? Its seems to be gone now.

Thanks! I am not sure what happened but clicking on the links says “not open for further replies”. I don’t see any knife info.

Do you have AR-Trvlr on “ignore” for some reason, it may even be accidental. The only reason I’m asking is because that page you screen shot says “show ignored content” mid page on the right hand side. Click that and see if all the posts load, if so, that’s the issue?
