Can anyone who is not sworn to secrecy e-mail me and explain how to make the flattening machine from one of these of just explain it here? Maybe a little thought and we could come up with a good idea ourselves.:)

Gouge,

I notice you are in Hampton. I lived on James Drive from 80 to 87. Not Hampton, but close. Are you a Yard Bird?? I was in X31 department.

Nope,

Not a yard bird. Came to this area in mid 80's while serving in the Navy. Nice area but its getting too crowded and the crime is a joke. Usually its the same group killing amongst themselves but its still scary:( . Trying to get back to the mountains of Georgia but my job is just to darn easy. I babysit a E-2C hawkeye simulator,(sit on my butt and watch the day go by)

You and I both know why the crime is going up. That stuff used to be more south in the city. It keeps moving further north through the city year by year.

I'm not certain what the question is, and if it's partly secret anyway...
 
turn the 6"x48" on with a selected belt and press down with firm even pressure what ever your are trying to flatten!:rolleyes:
 
As I'm sure you have all experienced trying to flatten a piece of metal with even pressure on a grinder. The result I usually get is either one end or the other gets rounded off. I had read a thread a while back about using a 6x48 grinder to make a device to flatten steel. I wish I could remember the makers name. Someone had said there was a picture in an issue of Blade with someone using one.

Do you mean one end gets rounded off or one end gets thinner than the other? The magnet method on a disc grinder with a foot switch helps prevent the rounding, but if there is a jig that helps to keep the thickness constant, I'd like to see it too.
 
I'm sure you're talking about the blade grinding/flattening unit that J.P. Moss designed and used to sell. A modified 6X48 sander.

I took the lock-back folder class from JP and saw/used the sander. I even bought a sander to convert....but I never did. I use a disc sander to flatten things.

I paid $2000 for that class, and the stiffest rule of Moss's was to keep the design of the sander to myself and those that had taken the class. I'd be happy to share the idea, but I gave him my word...and a man is only as good as his word...if he keeps it.

Dang, Nick, I'd'a taught ya for only a grand, but then, you'd have probably gotten discountable information anyway. :D

Heard ya did good at Blade. Congrats!

If the guy's not making them anymore, then someone should contact him and get permission to let the cat out of the bag. Why in the world did he want to keep it secret anyway? I thought that one of the great things about the knifemaking community was the open sharing of information!

It's part of the way J.P. makes his living, and feeds his family.
It goes part and parcel with his knife making classes. He still does this. In fact, it's his sole means of income now.
 
Disc sander with me too.
You don't have to spend $50-100 dollars for a disc. Just call grizzly and get a replacement for the 9" disc. I think they run about $15.00.
Just thin aluminum, but they work, and will hold you till, or if you get a thicker disc. You can do the same thing with Sears parts dept. Same price.:eek:
 
I've really tryed hard to understand the original question of the thread. I guess it is: how to flat grind. For me it has been very difficult to get a consistant grind without periodically switching ends of the work piece. Am I understanding the question correctly?? With the belt running it predominately hits the first thing it sees and therefore grinds it first and mostly. Regardless of how I have tryed even hand pressure it always grinds most where the workpiece meets the running belt. Am I missing something here? I just can't see where, regardless of pressure, it can come out consistant unless we regulate pressure at the back end in order to balance resistance.
 
So am I to understand that Mr. Moss only sold these modified units to people that payed for the class. Or were they open to sell to anyone?
