With the recent spate of nutcrackers going around, I thought of another little project that will please the little woman, and make a nice gift as well: a salt/pepper mill.

I got inspired after finally seeing one with a decent opening - then I saw the price - $85! Those Perfex's also are known to have a limited capacity. so a quick google search later, I found a supplier (http://chefspecialties.com/catalog/index.php/cPath/18) for the mechanism.

The hard part is how to fill it - I don't like the ones where you have to take the top off, because invariably with the constant filling the thing loosens up. The Perfex has IMO the best setup:

I was thinking of tapping the side with a fairly large diameter tap, say 1/2-20 and putting in a large, thin headed screw that could be turned out with a butter knife or a dime. Also, since it's tapped, you could make a funnel that would screw into the hole, making it easier to fill.

Thoughts, comments, suggestions?

Have you thought about using a electrical box type screw 1/2" 3/4" or even 1" the kind either die cast or aluminum for water tight boxes. they use standard pipe threads could be made out of yoor choice of materials. or the standard in most wood mill plans I have seen is a good ole cork, or rubber cork or lab flask stopper.
Don't know what your search turned up but here are my list of sites from wood turing.

I've had a pepper grinder for years that gets the top removed when refilling it. Wear is not a problem.

The thing gets refilled 3 or 4 times a year. Maybe it will show some wear in about 500 or 600 years.

Of course, the blades are another matter. They may only last about 150 to 200 years. http://bbs.homeshopmachinist.net//smile.gif

Glen is on the mark about locating a mechanism. Woodturning supply catalogs should all have them.

HTRN,

Here is a peppermill that I have had for years and it is fantastic. Easy to fill, grinds pepper like crazy, holds a ton, etc. Consider it the big brother of that whimpy Perfex.

Here is an overall shot, its about 10" tall, 1.5" diameter of the main tube, all brass.

Here is a top down shot. Notice the long handle for good power. The swivel knob on the end allows you to really crank on it. Much better than those wood tube style monsters.

http://www.maxscient.com/images/kilroy/DCP_2927.JPG

This is how you fill it. You take the acorn nut off and remove the handle and then the top cover. Nice big hole to fill. It also holds a ton.

Then tension on the mechanism is adjusted on the bottom. So you can take the top off and refill as much as you like. The mechanisms you found online look a lot like this one.

That brass 'peppermill' is really a Turkish coffee grinder - or it is identical to the Turkish coffee grinder that I have, anyway.

rkelper, you are right on, it IS a Turkish coffee grinder. It works much better as a peppermill than a coffee grinder.

Yah, it does look like a similar mechanism. If that's the case, then a tight fitted threaded knurled nut on top to hold the arm down, and threading the top piece so it screws off the body would make things a great deal simpler.

About the only thing that determines the "length" of the kit, is the shaft, which I can't imagine as too hard to replicate in a longer length. http://bbs.homeshopmachinist.net//biggrin.gif

I think a chunk of 304SS tube stock in an apropriate diameter, knurled and given that "brass bed in a sporting house" shine, with a nice long arm for easy cranking, say, 6", with a SS handle (https://reidecom.reidtool.com/xephr/edit/ITEM_GROUP?query=*START_WITH_ID=72012&query=*GROUP_ID=72012&query=*GROUP_PARENT=3713) on the end would do nicely.

Only problem is the cost of SS tubing - McMaster Carr has 4 foot lengths for anywhere between $170-240 depending on exact material, diameter and wall thickness. I'll have to see what the local scrap guy has the next time I'm in the neighborhood.

That brass grinder gives me an idea,I have a
3 pounder or 40mm shell casing that was cutoff that has been looking to be made into a project. a coffee grinder it is.

Hey HTRN let me know what size of tubing you need and I can get you a chunk for the cost of shipping it. My place of work uses alot of 316L and we have any size/sched in stock or in the cutoff bin.
