    Default Brown and Sharpe Dividing head

    Hey folks, I just got myself a dividing head. img_20200103_164628.jpg I Got an unbelievable deal on it, a whopping 47 buckaroos. I am going to do my fair share of research but is there anything major I should know about this dividing head? like quirks, limitations, and drawbacks? thanks for any advice.img_20200103_164643.jpgimg_20200103_164712.jpg

    Any gears with that? Mine has two additional "hole plates" (total three) which I think is standard, at least in my size.

    No, I didn't get any gears, I'm going back next week and I know there are boxes of gears laying around so there may be some that I can buy or take if he feels like I paid for them with the dividing head. also no extra plates, unfortunately, I didn't see any. I didn't look very hard but again next week ill see if I can find and grab them.

    IIRC the trunion type shown are different internally than the quadrant type shown in John's brochure.

    If you can avoid it, do not remove the spindle and bearings, they may not go back together as accurately.
    I have the other version, model 2.

    Thanks for posting . It helped identify the one i picked up awhile ago. Old and crusty was not able to find name till i saw where it was at on yours. So small on mine had to use a eye loupe to see. Letters were .050 tall. Nice score with all the gears. Mine has non. Dont think ill ever need em anyways but would be heck of a project to make.

    Before setting up gears make sure you have disengaged the main spindle from the worm drive. The main spindle must turn freely. Behind the hole plate, on the bottom there is a locking pin which engages into a hole in the plate to fix the hole plate. Push it out of the hole in the plate. It is mounted to a knurled knob (eccentric). One of the nuts will lift the worm gear up and free the main spindle. Look for some arms with a long slot for mounting the gears to the end of the table.

    I know this thread is. a little old, but not that old.

    Ran across a set of gears that are probably for a Brown & Sharpe dividing head.

    Here is the eBay link for the listing.
