Normally, I would have posted this as I made it. However, I wanted Ralph to receive his gauge before I posted anything. You can read about it from him here.
Basically, what Ralph wanted was a solid brass dovetail marking gauge, based loosely on an older Hayward design. Instead of the double angle on the gauge that most of us are accustomed to, he wanted a 1:7 slope on one side and square on the other. Sure, you have to mark and flip as you lay out your dovetails, but you also have a built in square on your gauge. I think Ralph is onto something.
Following is about how I made it. Just highlights, really. Sometimes I forget to take pictures when I get going.
|Before starting, I wanted to make a 1:7 gauge of my own. This will get used later to mill the final angle into the finished product. It will replace the parallels that are usually used while milling a part.|
|This was a good chance to test out my 2" indexable face mill. What makes this one different is that it uses round inserts. I wanted to see what kind of surface finish it could lay down.|
|Yup...I dig it!|
|Once the dimensioning was done, it was time to form the cut aways that make up the shoulders.|
|Sometimes you need to get real close to the vise. But hey, .001" of clearance is still clearance in my book! This was more like .015".|
|Now we get to use the angle gauge from earlier.|
I'm thankful to Ralph for putting his trust into me to make this tool for him. Making parts like this is what I enjoy most. At work, or at home, I love to sit on the milling machine and play (um...I mean work).
I'm so glad that he is happy with the finished product. I get a little nervous when I make stuff. I try to hold myself to a high standard, which means I always feel like I may fall short.
Thank you, Ralph!
