platen question

First I am not "fluant" in anything electrical . When I was working in my first shop (which had a hoky electrical circuit) all I had to do was get close to my KMG & she would zap the crap out of me. Since putting up my new shop with a new electrical system ,done "by the book" , I have not been zapped one single time. Don't know why , how or anything else. Just giving my input & my situation. For quite a while I thought something was bad wrong in my first shop with the electrical or the grinder. Not sure what was going on, it has stopped zapping me though :confused:
 
I didn't get the shock until I installed a ceramic platen on my Square Wheel. Now I do, since the ceramic doesn't conduct electricity.

I also have added a ceramic platen on my Burr King, but it doesn't shock me.

Both machines are direct drive, no rubber drive belts involved, so the difference between the machines is simply belt SFPM. The Square wheel runs much faster than the Burr King. Both machines are mounted on steel stands.

So when I mount a new belt I spray the inside while running with static guard. It works immediately and the belt doesn't need to be sprayed again the next time I use it.

My Mom gets the spray at the grocery store.

Now I didn't invent this process, someone on the Knet forum advised me to do it. To my everlasting thanks. :)
 
Thanks, Don. I'll give it a try, next time I get the hankerin to do some grindin. :)
 
Next time??

I do it 6 days a week, even sometimes on Sunday afternoons. But I like my boss. We get along just fine.:)
 
Hey Fitzo, my comments were aimed mainly at the new forum members who joined since last winter's discussions about what to do about static.

David, you probably had a bad ground on your machine when you had the first "hoky electrical circuit". Glad that the zaps that you got were not severe.

Don, all other things being equal (they are not) your Square Wheel is more likely to build up more static charge than your Burr King since it runs at a higher SFPM. You can try spraying or wiping fabric softener on the inside of your belt before each grinding session. It would probably be less expensive than the Static Guard. The Staticide that is sprayed onto workbenches and floors in electronic manufacturing facilities is apparently a lot like fabric softener.

If you are working indoors, a humidifier will help reduce the static. If you have hard water, fill the humidifier with filtered water otherwise the minerals in your tap water will come out of the air as white dust.

My thanks were sincere, Phil! I mean that! I had forgotten that thread, going round and round and getting nowhere. You reminded me of something: I don't want do that any more; it's not worth the frustration. My fix worked for me with my setup. My perspective about static generation and control comes not through electronics but through static generated by fluid flow through pipes and hoses and falling liquids and such; bonding and grounding to prevent static sparks that could generate solvent fires in chemistry plants. At its root it's about how and where electrons go, and the principles remain the same. I can translate it adequately to protect myself in a knife shop. This here is best left to someone like you who can communicate in terms of machines and electrical stuff.
Slowly, I'm learning... I want to stick to the lighthearted stuff and give IG crap. :D
