Any interest in a short run of grinder radius platens?

EDIT, 12-4-2010:

I started another sale thread for a second batch: http://www.bladeforums.com/forums/showthread.php?t=796545

Please go to that sale thread if you are interested in buying one of these.




I'm machining a curved platen for my KMG so I can simulate a large wheel grind. I'm making one for myself for 36" diameter. While I'm setup for it I can make extras if folks want them. I have enough steel on hand for a few, though if there is interest, I can get more before I start.

The purpose of this thread is:

to determine interest, so I can figure about how many to make (this is not preordering, I'm just getting a feel)
to determine the preferred diameter people would want
to determine the level of finishing folks desire
to determine what bolt hole pattern people would want beyond the KMG standard

I have no interest in getting rich making these, I simply want to cover material, tooling, HT and machine time. I also don't want this to become a large project, so it would be my preference to sell them cheap with no additional finishing (I'm a machinist, ya'll are metalsmiths, I figure most of you can finish them yourself better than I can).

It would probably cost in the neighborhood of $75 via check or paypal. And figure on another $5 for shipping. It would be A2 steel at around HRC 62. As machined and heat treated, no special finishing.

If folks just really want theirs finished I could do that - but it wouldn't be cheap.

So, is there any interest? (you are not committing to buy, but please don't leave me hanging). What diameter wheel would you want to simulate? Will "as milled, in heat color" work for you? What bolt hole pattern do you want beyond the KMG 1/4-20 6.75" center to center?

I did a micarta one-time-group-buy about a year ago that went very smooth. I'm hoping this can go equally smooth, so I would set up a process similar to that sale, which would be described in detail in a sale thread over in the appropriate sale forum if/when I do this.

I would definitely be interested in either a 36" or 48" radius - I have a Bader3 but with Rob's flat platen attachment - which is assume has the same hole pattern as his one for the KMG

PLEASE correct me if I am wrong, Rob or anyone else

Nathan, I would be interested also. I have the KMG flat platen. 36" or 48" diameter would be great. i could use either for my swords... No problem with 'as milled, in heat color' finish.

Thanks,

I'm interested,either 36 or 48 inch radius starts to approach the diameter of some ofthe medieval water driven wheels so either works I know how to finish metal, I have a Bader platen and wheel setup that I'm building a grinder around,

Hello Nathan,

KMG standard mount. 48". I'm in if you make these. I'd prefer to finish myself. Thanks!
 
I don't even own a KMG (I've got a Coote) and I'm in on this in either size in the KMG pattern. I can use this one way or the other regardless of what machine it's made for.
 
Do you take knives in trade? :D
Interested in a 36" KMG style
What would the lead time be?
 
I am in if you can make the screw hole 3/8" x 16. I just got off the phone with Bader and this was the dimension I was told.

A set of 3/8-16 holes in the back of the radius platen should not be a problem. What is the distance center to center? Is the pattern centered on the platen? Is the platen 8" long?
