New To Me Dividing Head

Got it! I inspected it well packaged arrived intact,I gotta go work so I will get it into the shop tomorrow ....It's a heavy beast all I can do to lift it....well it's heavy, I'll post pictures tomorrow.....and count the holes they are not marked as far as I can tell......and I was right there is a row of holes that are for direct indexing.....all the other heads I've seen are different than this one ...Carrolls included ....
 
holes are 15,16,17,18,19,20. divhead 003.JPG divhead 002.JPG I don't think it has direct indexing. That row looked bigger but just had some slop......works nicely....I am a happy person! I paid a total of 160.88 that includes shipping, I know it's a lot, but I really have been wanting one and it will eventually pay for itself ,right?
 
cleaned it up as muck as I am going to....One of the three screws that holds on the plate is missing so is a washer for the plate .....that's going to cost me another 10 cents. I probably have them here somewhere ....This is a well crafted Head with very little wear on it. very little backlash if any....

You didn't pay much for it. Ck eBay prices ,there charging that much to ship smaller ones. Good luck with the beast , I always say most times bigger is better. I'll bet she cleans up real nice and is smooth as silk . Let's see some fancy helix splines and gears .
 
Hi Rafe,

If you are looking for more dividing plates check post #6 here:
http://www.hobby-machinist.com/threads/i-am-in-need-of-a-vn-dividing-head-plate.36623/#post-315155

When that poster was looking for more dividing plates, I photographed and posted some that my local used tool place had.
I believe there were still there last time I looked.
Let me know if any of them look right for your "new" dividing head.
If you send along the ID, OD, bolt circle dia., pin size and # of holes you need I can check this weekend. Let me know.

Oh and I almost forgot....do you have a chart showing the number of full turns and number of holes for what circle to get a particular number of divisions? If not, let me know the worm-gear ratio. Last time someone was looking for a chart I made a perl program to figure it out. I could resurrect that program and provide a file or table.
You could also look at this discussion for a few on-line calculator options:

Hello Brino, I picked up a 21,23,27,29,31,33. on E=bay today,I do appreciate you offering, I'll just keep an eye out too. the size seems pretty standard 1 1/8 X 5 with a 3 hole patern, if you happen to be there and feel like checking that would be great, to be honest I don't know what I will need ,,,,but the two I have will open a lot of doors....I think! I am going to lube it up and reassemble tomorrow ....not even going to paint it,it has a great look and earned it's coat

I've been to Olga's Diner many many times :)
 
No more Olga's , state practically stole there property. Highway changes no more circle just headaches. The had the best bakery around for many years . And good food too.I live a stones throw from there. Yupp spitting distance
 
I checked out the chart that Brino (thanks) put up and it does help ...Looks like I have the #1 and #2 (standard) next I'll want is the #3 ....That will cover a lot of options ....Kinda like collecting baseball cards Right now I could do up to 40 holes ...except 13,26,39 and then a lot of higher numbers too...It would be unlikely I'd ever need more than 1,2,and 3 plates and plate three is iffy.....but would be nice to have. I am off today looks like more rain so I'm going to reassemble the Head .....
 
Rafe,

Just be sure that the chart your looking at was made for the same worm screw ratio you have in that dividing head.
If you do not know the ratio, you can mark the output shaft against the base, then rotate the handle in one direction (counting turns) until the line comes around and meets again. Warning, it may take 30, 80 or 90 turns of the handle for one output turn.
