Today I went to my friends shop, he will do a lost PLA casting from my 3d print and from it he will make a rubber mold to see how much it shrinks so I can do new PLA rings a % bigger to compensate for shrinkage. This will take the whole week.
What I found using this tool is that is great for bulk removal, but up in the grind when you are about to finish, specially in thin knives like I do, I prefer to have the biological thermometer (aka finger) touching the blade.
What I thought would be a good idea is to drill a 1/8" hole below the knife seat and glue a broken carbide tool there, I left the space for it, maybe leaving a small divot as a guide for someone wanting to do this is a good idea. Didn't think about the prices, but as posted above, the one I saw...
Oh I see, but we all know a belt grinder is not a lathe that can grab a finger, an arm or a whole person... Worst accident I had at the grinder was a 36 grit belt seam that failed and left an interesting mark for a few days in my torso and of course scratches here and there...
Thought about this, but that will leave the index finger away from the blade, I found that the closer the index it to the belt the better.
Cast brass or aluminum are my options, plastic could work but I think it will deteriorate sooner than later.
Not long ago I saw a video for a grinder ring and it seems the idea got stuck in my mind... So I put it to work instead of procrastinating remembering videos :D
The idea is to save the pain for your index finger when grinding long freehand sessions, I use it for the bulk removal and it works...
I get the sarcasm :D but always there is room for improvement.
I don't agree to the statement that says that is better to start with a jig, because it delays the proper learning, what a jig does for a newbie IMHO is to cope with frustration since the skills aren't there yet. Buy if you use and...
