Since works been kicking my but lately, and it’s been to cold to comfortably work in the shop, I’ve been spending my nights becoming more familiar with my new camera. I’ve been wanting a new camera for a while, but kept putting it off. However, with the wedding/honeymoon fast approaching I decided now was the time. I spent a good wheek researching what camera to get, and ultimately settled on the Panasonic G7. It’s an entry level micro four thirds model, that should do just about everything I require from a camera. It’s 16 megapixels, shoots 4k video, and the interchangeable lenses will let me get into macro photography. The following shots are my favorites from the last weeks.

Two of the goals I set when designing when designing the tool rest where specifically related to adjust-ability. First and for most, I wanted to be able to adjust the rest quickly. spending 15 minutes to set a tool up so you can use it for 2 minutes is always a buzz kill. Secondly, I wanted to have as much adjustability as possible. After pondering it for a while, I came up with the slot nut idea. It gives me 1-5/8″ of front to back adjustment, and it can be adjusted one handed.
The following video shows machining the slot nuts. While they look simple they could be difficult to make if you don’t use the proper order of operations.

Now that I’ve completed both the wheel bushings, I can dig my teeth into the heart of this project, building better tool rests. I’ve never seen a bench/pedestal grinder that came with what i would consider a good tool rest. To me a good tool rest is one that wraps around both sides of the wheel, and has 2 to 3 inches in-front of, and on both sides of the wheel. In my opinion a lage work surface makes it much easier to grind metalworking tools, specifically threading and form tools. With regards to woodworking, a large work surface makes it really easy to grind plane and chisel blades.
I’m going to purchase a Oneway Wolverine jig for grinding wood turning tools, so the rest i’m building needs to mount in a way that it won’t interfere with it. Thus, my rest will mount to the wheel guard like the stock Baldor rests do. The following video shows the machining of the first of 3 parts needed to make my rests, it also gives a brief overview of what my rests will look like and how they will work.

A CBN grinding wheel is a significant purchase, usually costing a significant portion of what the grinder it will be mounted to did, and in some cases even more. Additionally, it can’t be trued like a traditional aluminum oxide wheel, so care must be taken minimize wobble & run-out. In the following video, I show how I made a bushing to mount a D-way 180 grit CBN wheel to my grinder. Besides centering the wheel on the shaft, the bushing was also designed to act as a space that would accurately center the wheel inside the housing.

Shortly before Christmas I acquired a new tool for the shop, a Baldor 8100W 8″ slow speed grinder. For almost a decade, I’ve used a no-name 6″ grinder for all my tool sharpening needs. While it always got the job done, it was never a tool I enjoyed using, so the Baldor is going to be a substantial upgrade in more ways than one. In this first video of what will be short series, I discuss truing up the stock flange washers supplied by Baldor, and I show how I made a steel bushing for mounting an aftermarket aluminum oxide wheel.
