building the Gingery dividing head


Thomas Janstrom
 

So I bit the bullet and decided buying a dividing head was not an option, all I could find were too big for my machines or too small for the project or just plain junk... Anyway here's where I'm at as I now await parts to arrive.

Subscribed, and will follow with interest. :)

Have you followed Peters series on building the dividing head.

Last time (before today) that I looked at Amazon, they had a 5" B&S #0 clone for about $225 from a bunch of different sellers. Today, of course, only one, and for $345. That might still be too big for your purposes. It's a bit too big for mine. I want one right at 4". I've got an Atlas MF horizontal mill, and a Harbor Freight 44991 mini-mill, and a Smithy CB-1220XL 3-in-1 machine sitting here where I could use them to make change gears for my Atlas TH42 lathe, the Harbor Freight 93212 7x10 mini-lathe, and possibly the South Bend Heavy 10L once it gets restored.

I've also got a really cute little 3" H/V rotary table, and I found a tailstock on Ebay that I could probably block up the rotary table to use. Had you considered using indexing centers? They use a change gear to do the indexing. Vintage Machinery has blueprints for the Lewis shaper vise, and Lewis Indexing centers that I could use on my Lewis Shaper, as well. The Atlas & SB lathes will need gears around 9" across for the 127-tooth metric transposition gears. The HF mini-lathe uses module 1 gears, so those are easily printed on a 3D printer, which I have, and have even printed one of the gears. Was looking at doing 3D printed gears for all the machines (before I got the Smithy) the print times are horrendous for the larger gears.

I also have the Gingery Dividing head book... I'll be following your build.

Did look on Amazon but being in Australia not everything is available. Anyway the project is underway so I'm kinda committed now lol. 

I did think about indexing centers but out of all the gears that came with the project lathe, the only gears with the required tooth counts are the ones on the spindle shaft... Besides there are a bunch of missing change gears to get it able to do thread cutting again. The tumbler reverse and some of the mid range gears are there but not enough for the full range or metric (I doubt it was ever able to do metric). Oh yeah 8TPI lead screw which is in remarkably good condition for being ~120years old...

I built the tailstock support but use it with a 5C collet spin index and a small 4" rotary table.  Both those were really cheap at the time so it never seemed worth the time to build them.

Making some progress on machining the castings... And the worm and wheel finally arrived, I wish I could have sourced these locally but ended up having to have them shipped from the USA at a greater cost then the parts.

Nicely done!

It looks like you're doing great with the little time you get here and there! The "authentic" gingery feel is real here, using the minimum tools required to get the work done.

The next installment, Man I'd kill for some extra time off this is a fun little project and progressing well.

Had some interesting things crop up that needed doing, like picking up an 18" stroke shaper...

Braggart! ;)

I was going to go back to sleep, but now I have to watch your video. Two subjects dear to my heart in one video.

Look for the video called "Things are starting to shape up"... This will be one heck of a project as you will see.

Left you a comment, and a thumb up. I envy your shop! And it's going to be much better!

I've sent you an invite to join the Metal-Shapers-and-Planers group at groups.io. We don't have cookies, unfortunately, but we do have a manual for your shaper.

I sort of bypassed the building of gingery machines to buy ready-built or restorable machines, but I'm seriously looking at building the dividing head you're doing. I figured with the skill level I had at machining and making stuff I'd never have a shop if I did it the Gingery way. I'm far enough along in that process now that I can see my way to doing some of those things here in the near future, so I don't completely lose out of the learning involved.

Nice!  I've considered making one too.  Like Bill, I ended up buying a lathe, vertical mill, and shaper.  But I am thinking about building the horizontal mill and maybe dividing head.  I have invested in a set of ER40 collets and tool holders to use with my mill and was looking for an ER40 spin indexer but there don't seem to be any.  5C indexers are pretty cheap-ish on ebay, but I would have to buy a 5C-ER40 adapter to use one.  And then that could be used in the Sheldon lathe, with an adapter.  And a tailstock to be used with either the spin index or dividing head could be used on the mill table and possibly the shaper too

Very cool!  Really drives home the discussions regarding the importance of rigidity and close tolerances on all surfaces, locking unneeded moving parts, etc.

yeah, and accounting for wear over the past 20 odd years is hard too. The carriage and cross slide/compound need work, I might end up hogging them out now that I have a mill.
