The best advice I can give, is power equals depth and the coil size equals sensitivity. The larger the coil, the lower the sensitivity. What helps is to make a oval search coil. It increases the depth but you have a small point of fokus. It also lengthens the search cone so to speak. Giving you more a tent shape than a funnel shape. Hope it helps. Btw. This is a very good detector...

This is for anyone to answer. Can this project be modified to do cnc and lazer cutting/edging? BTW all ready busy assembling Y and Z axis

Why haven't I thought of that moment... Would you mind if I add that to the instructable?. I was wondering what i can use to buff the grips a bit. Heatshrink will work wonders...

So far no comments. This is either a good instructable, a bad instructable or you don't have any questions...

I have found that oil works better. I use a high carbon oil like used motor oil or gun oil. I only use about 2 or 3 drops per knife and it smooths the edge more. I also recommend the finer side of the stone for a knife that you sharpen alot, like a kitchen knife. The coarse side is mainly for a knife that has lost its edge and you are trying to get that edge back. Great instructable and beautiful photos.

On my kitchen knifes, twice while cooking. I do it on the sharpening rod. My more precise skinning knife about once or twice a week. It depends on the thumb test. If i draw the blade across my thumbnail and it does not stick I sharpen. (BTW great bio on profile. Added a chuckle to my day)

Excellent build. I built one a few years back. Mine was solid and had a push pull prop configuration. It drained my battery pretty fast but it's job. I'll try this project this weekend. Thanks for the extensive detail as well.
