Indexing plate!

-20F this morning again...........:cool:

This morning's project was to finish up on an indexing plate that I had started the day before. Not that I really needed
a project but wanted to test out the bolt circle feature on my Mitutoyo digital readout. As luck would have it I had a
steel disc or the right thickness but a little larger in diameter than the original indexing plates. I picked 40,44, 48, 50, 55, and
60 divisions but maybe using some prime numbers would have been better, not sure at this point. Anyway, I still have
the flip side to drill out. This is not a difficult process but rather a time consuming and requires one to be careful not to
make an error in drilling. I used a center drill for the whole process for the sake of rigidity. It was quite a bit of work
so had to show it off to all you HM folks. At least now I know that I can make pretty much custom make any indexing plate
I desire.

Here's a couple photos of the results:P1020099.JPGP1020097.JPG
 
Ahhh! twas a wonderful thing hanging out with the Sargent, young, fearless, ignorant, yet so sure we were practicing the gospel, and after all, all you need is love. (pardon the chronological leap) Mike
 
Mike,
I'm going to have to rummage through a pile of vinyl and see if I actually might have the album. I havn't looked at
that stuff or played any of them for years.......:rolleyes:
 
The indexing project is taking a new twist as all of the indexing hardware and crank assembly were not big enough to reach the outermost
set of holes. I copied the original parts and made them longer to fit the new plate. It's pretty much done but a new pin assembly would
be good as the original one is for slightly smaller holes. There is a lot of complication to that part so will have to give it some thought
before making another one.

Here's a couple photos of the work in progress:

The original divider things were made of plastic but I made mine from mild steel so much stronger. It was a bit of work to make the
little rings and the divider spacers had to be welded to the rings.
 
Nice job on the pointers those should hold up much better to any unintentional abuse. I have a fair amount of vinyl around, but nowhere near what I had at one time. I have a nice turntable, but it needs a little work on the changer mechanism, and I need to find an amp with a phono connection. Haven't played any LP,s for probably 20 yrs, but want to set up for it in the new shop. Have gotten pretty used to the digital I-pod and sattilite radio, but a little nostalgia once in a while would be nice. Mike
 
My heavy turntable got repurposed(probably not a word) into a disc sander which is mounted on the back side of the ram on my mill
and I use it every day.:grin big:


edit: I looked it up and sure enough it really is a word..............................
 
Interesting! I thought of that too for an outer most set of holes on side one of the plate. The flip side is reserved for a time when I need it
for something out of the ordinary. I would love to make a 127 tooth gear for the Monarch but would need a hob for that I suppose.
It would be a pretty big gear with large teeth but would be an interesting project. I'm not really sure where the gear would go either
in the gear train or the DP of the gears for that matter. Maybe someone on here knows where the gear would go.

If I have the time, I will drill the 127 holes this morning.:)
I had a Monarch CK 14" toolroom lathe, and it was not physically possible to mount transposing gears on it due it its construction; for metric transposing, one needs the 127 tooth gear joined side by side with a 120 tooth gear; some time ago I posted a chart of all the change gears necessary to cut most all metric pitches on a lathe with 4 TPI lead screw.
 
The chart that I posted on metric transposing gears was from a American Machinist data sheet that was originally published in the magazine; it works with most any industrial sized machine (except, notably, the 14" CK) the info can be interpolated for other pitches of lead screw, quite easily.
I posted it with permission of the publisher, for all to use and enjoy, including Mr. Kite ---
