Hi Guys, would anyone happen to know how many degrees apart the 10 holes are on the vernier plate of a spin indexer?
The outer plate has the 36 holes at 10 degrees apart.
the vernier plate has the 10 holes numbered 0 - 9.
I want to be able to index 360 degrees every degree.
I cant wrap my head around the math.
thanks

One
If you put the pin in hole 1 you indexed 1 deg 2 = 2 deg, 3 =3 deg, ------------ 9 = 9 deg back to zero and your on 10 deg.
Hope this helps

Mark,
Unless I have missed something critical here, my "spin indexer" has normal 10° increment indexes on the primary index ring and 1° increment indexes on the vernier index ring. Thus, I start at the 0° position and move to the (say) 20° position -- and then place my index pin in the (say) 5° vernier hole, remove my primary index pin, and rotate the indexer until the vernier pin drops into the next hole. I have now moved 25° from my initial position. Your 0° vernier hole should index when the primary index pin is in any of the 10° increments. My "spin indexer" is old enough that it has 11 holes on the vernier (0°-10° for double-checking). It is a shop-made tool given to me by a retiring machinist back in the 1960's. I know that I have used commercial "spin indexers," but my fingers know my own tool best.

Manual here that applies to pretty much all the similar spindexers.

Worked ok for me also.

thanks guys for the replys. The holes in the vernier do indeed have to be 1 degree apart but that would overlap them. I got the answer on cnc zone to make them (the holes in the vernier plate) 11 degrees apart which makes sense to me.
thanks a lot.

it worked for me today but it was not there when i checked it first time. cool beans man will give it a good reading thanks :headbang:
