My Webster's New International Dictionary, with some 2660 pages of definitions says bur is a variant of burr. There are at least 15 different definitions under burr, including the use of the form bur. It also includes the "bur" made by a burin when engraving metal.
PS...published about 1965.
I built that as a tribute to my 12 1/2 years living on Kodiak Island. Each of the 18 animals depicted have stories of my adventures on the Island. The black walnut for the back, sides and neck were cut from boards my scoutmaster of many years ago cut from his property. They were passed on to...
The upper photo is in the finished state. While it is playable, I don't play stringed instruments and have had little luck finding anyone that plays baritone uke.
Like I said Ed, you are not alone. I don't collect or play guitars but have built a few for fun and also to experiment with engraved inlays. Here are photos of a baritone ukulele I built for fun and to experiment with engraving inlays. Sort of "before and after" shots
Ed, glad you are "into" engraving so thoroughly. I've been at it for over 50 years now and would surely be lost without my daily dose of cutting! Lost my wife over 21 years ago now and having my engraving to fall back on was a great help and still is!!
Here are some modified tools I made to engrave the guitar tuner base shown. The two on the right, made with much less lift might be an idea to think about. The six uprights on the tuner base got in the way of almost every cut I wanted to make.
I should think acid etching for the removal. I have not used this method but know other engravers have. Maybe someone will pipe up with info or point you in the right direction for information.
As long as you are VERY selective in what you buy it can work out well. I bought a roll-around tool chest, 4 drawer, of heavy gauge steel. I liked it so much I later bought a second one when it was on sale for 99 bucks.
The #10 lens focuses at about 4 inches so you will need your vise high enough so you don't have to bend over and tire out your back. Works well for me.
One of the things we all have to learn is that background, whether removed or not, is very important to the quality of the engraving...and takes a lot of time. A little less background and a bit more scroll helps.
Have you tried an Optivisor? I use the #10 lens and see just fine while...
Perhaps you can set up a stand-alone checking account just for this purpose and have the money wired to it. You can then close the account...if your bank will accommodate you.
