Not sure if this has come up before or not. I bought a BS-0 Dividing head some while ago, and it had no manual or instructions of any kind in the box. Zilch.

Came upon a Grizzly Model G1053 manual, which is available on their webside and (for me) is a great manual with lubrication details, parts diagram and lists, etc. Minor differences in nuts bolts tapers etc, but contains a lot of good information, including dividing charts. Enjoy.

Thanks

I have the same dividing head and it did come with a manual but the Grizzly one is more comprehensive.

Did you see the previous thread last month?

It provides various links including a strip down video which is rather long but instructive. He fails to remove the wormwheel – FYI this is because it is located by a keyway and the key is intentionally deformed with a hammer to make it a rigid fit. An interesting economy measure to avoid having to machine to tenths.
The Grizzly instructions are here and are up to their usual standard. However they fail to mention the end float adjusment screw plug item 15 which may need adjustment. Unfortunately it is locked by a grub screw from the front which graunches the thread – how I hate such design sloppines. The spacer 39 on the wormshaft is I think a plastic collar to help preload the shaft and protect it a bit if things are not adjusted correctly but it is worth understanding that for ultimate accuracy the cutting forces must apply anticlockwise rotation to the chuck (seen from the work) so that the worm shaft pushes against the above mentioned plug.
