???small Rotary Table Dividing Plate Set???

[Whyemier]

I have lately seen on E-Bay sets of 'Small Rotary Table Diving plates'. Curious.

I will reveal my ignorance by asking; "How do these plates attached to the small rotary tables?" I have a small (4" only) rotary table and see where these might be useful (If they'll work with my small table). Anyone have a photo or explanation of the application to use with the table?

Thank You,

Whoops! Found this photo and it's for a 4" so question answered.

good, you found a picture, only a few sizes are critical for mounting the plates:
1) you want the centre hole size of the plate to match your hub
2) they often mount with three screws, you need those holes to align (hole circle diameter and hole size)
3) you need the pin holes to be a nice tight fit on your handle pin
4) you want to be able to reach all the hole circles with your pin (handle radius).

Also, pay attention to the worm-gear ratio and the number of holes in the circle. There may be certain plates that are more useful than others depending if your worm-gear ratio is 60:1 or 90:1 or something else. If you do not know, it is easy to find out, mark a spot on the output shaft and count handle cranks for one full output shaft rotation.

If you do not have a table that shows how many full and partial turns to get a specific output angle post back here with your gear ratio and someone will have them. If not, a few people have written programs to figure them out, I did, but I have to dig to find it. There was a post here a while ago with a few charts uploaded and a few links to online calculators. I'll see if I can find it.......

I got that very same rotary table and dividing plates along with a lot of other stuff I've never used (yet).
I just finished dis and then re assembling the table along with new grease and realignment of the parts
so that they work (sort of) Not the smoothest and most precise piece of equipment, but it was free, and I think
that I can get it to work. Probably a Grizzly, but no manual, parts list, instructions etc seem to be available anywhere. I have
no idea what or how to use the plates or what any of the ratios are. Any info would be appreciated as I'm sure
Whyemier would agree.

CHuck the grumpy old guy

Hmmmm? Got to thinking, I picked up a couple of dividing plates in a box of gear cutters I acquired some time ago. Only paid about $20 for the whole lot, if I remember me correctly. Good price considering what they are going for new and on E-Bay. I might just have a project going now. Make an adapter to fit the center of the plates that will fit the spindle on the rotary table. I'd have to make the indexer handle too but a little trial and error won't hurt. Could be I already got what I was thinking of buying...or part of it.

I have the manual for the 6" version if it would help.

Hey @BROCKWOOD , if you wouldn't mind uploading the manual to the "Downloads" section here could help many others.
If you are set up to scan to PDF it might be fairly easy and very useful.
Thanks,

While I can't stand that my scanner only does PDFs, seems this will aide in this 1 situation. I'll tackle it in the morning after my shift.

Thanks Brockwood, It will be undoubtedly appreciated by multiple users here.

Downloads does not accept *.pdf extensions. Here we go again. PDF here & *.jpg in Downloads. Enjoy. I'll be in the Shop!

pdf's are a great way to hack some ones computer. They require all sorts of permissions and access to the back end of you computer, so hackers love them for sending in nasty stuff. They are really remarkable in how flexible a document can be, but not worth the size and danger imo.
Look to see if your scanner will "scan to text," most modern scanner will do this. Save it as a pdf (unless you have the option to save as Word), then open it with MS Word and save as a Word document. After that, you can "publish," or "check meta-data" and strip your personal info out of the document so you can upload it. Remember, you are your meta-data - it is not safe to upload your meta data, and no one should ever be able to look at it.

'preciate all the work you did uploading, that is a lot of stuff to cut and paste.
