what are the holes near the spine for?

Just an accent for some brass dots.
No functional purpose

Due to safety concerns, I made my grinder base tall again. Grinding while sitting down was really nice and easy to do (locking my elbows with my knees made the most stable grinding I've ever done). However, no amount of comfort should come in the way of shop safety, hence my decision to revert the base.

PS. Pro advise, don't talk on the phone while measuring, unless you want to make twice.

Tony what was it that concerned you about sitting?

Even though it happens rarely, a knife might go flying while grinding, usually it happens when a belt breaks or the tip gets caught.
While standing, the trajectory of the knife is towards the feet. Sitting down (or at least the height of the base and chair I had), the trajectory was straight my belly.

Between the two options, I decided to go for the feet.

that's some solid thinking. 👍
The CAS bros have a pretty interesting set up where they sit, but instead of holding the knife edge up at 90 degrees with the ground they hold it with the edge facing them at around half that angle. All freehand of course, no tool rest or anything. The footage I saw they were using a big wheel, I don't know how that set up would work out with a flat platen.

That's good to know. I do a lot of work sitting at a two wheel Burr King but all of those operations are under the wheel with the trajectory away from me. When I work on the top platen the belt is in reverse so things are moving away as well. It's a scary thought for sure. I've seen a few instances in the knife shop where a blade would get away from a guy at the buff and launch straight into the ceiling.

Cas brothers were the reason I made the short base and it does work quite lovely. One day I might give it another shot with this variable in mind.

We tend to forget the trajectory a blade might take, that's pretty much the reason I don't use a buffer.

Once that blade starts turning its like Russian rullete until you hit the stop button. Gave me a heart attack or two..

Always, always, always clamp before drilling metal. big C clamps work on drill presses. Since I got my mini mill, all metal drilling is done on it, as the clamping system is strong and very adjustable, and the ability to move the table makes drilling in the right spot much easier

Beautiful day today! 70's and partly cloudy, before the rain hits tonight. Got some work done, tangs tapered, spines rounded and polished, hollow ground bevels polished, and thumb serrations cut. My back is sore, my hands are sore...but I like the results! All in S90V.

The rounded spines are a really nice touch.
 
been in the habit of grinding bevels after heat treating, so I decided to change things up and do it before. The first half dozen or so knives I made- years ago- were all hand filed and hand finished, so doing all the work in advance of ht was mandatory. Now with the machine, it don't really care if the material is hard. One thing I have noticed though, is that annealed steel dust will just not combust anything like hardened high carbon steel dust will. It also doesn't seem to clump together magnetically in at all the same way.

I'm now convinced that doing the bulk of the stock removal prior to heat treatment is safer, and therefore that's how I'ma do it from now on. I also like the feel of grinding soft steel, now that I'm a bit more used to it. Of course there is an increased risk of warpage in ht, but I can accept that in exchange for not burning my house down.

ever had the steel wool you've ground off your blade collect in an idler pulley and catch fire? Looks pretty neat, but...

Apologies for the blank post, I was trying to post a picture but couldn’t figure out how to add an attachment…
