This thread is to give anyone with a mill capabilities with the measurements to fabricate their own. There will be repeated information and its not professionally drawn. I will be adding photos and information throughout the day.
When I'm finished I'll say complete. At that point if I have missed giving necessary information please point that out.
This is intended to be a reference post.
I will give the specs for the micrometer dial later.


Edit. one measurement I think I missed is the measurement from the flat for the cover plate to the flat on the bottom. is 1.353

20201228_180846[1] (3)_LI.jpgI missed this measurement.
The idler gear shaft is 1/4 with a 3/8 shoulder the gear rides on.. The drive gear shaft is 5/8 turned down to 3/16 . The drive gear and shaft are all one piece . That could be re-engineered.

Both gears are 35 teeth with a 1.09 circular pitch and a 1.18 addendum circle. The idler gear is bronze with a 3/8" bore. The drive gear and shaft are all one piece. I think the right gear will have to be fit to a fabricated shaft. Its a 14.5 pressure angle and 35 teeth.
I'm having trouble finding a catalog to locate these two gears. If you can find the part numbers please post them

Both gears are 1/4" thick

Here is the worm gear.
That first photo in the link must be a generic file photo.
Photo # 4 the drawing is completely correct For my worm gear.
Two screws need to be drilled and tapped and a pin drilled in the hub.


Part # g1027 is stamped on my worm gear.

A critical measurement is to the milled surface of the bosses on the side with the drive gear and the idler gear. The idler gear meshes with the gear segment on the taper attachment.
From the center of two mounting holes to the flats on the gear bosses is .525. THIS IS WHERE YOU MUST VERIFY DURING FABRICATION.

The casting is 3/8 thick between the worm gear boss and the drive gear boss on the opposite side and the worm gear must align and mesh with the worm.

Verify Verify as you fabricate
 
This thread could include the specs for the bed taper att.bed clamp.I should have added bed clamp in the title.
For square dial.
Feel free to post if you have a drawing with specs.
I can check specs against my clamp.
 
I am watching your write up closely and may try to retrofit onto my 16cw.
Please post the actual boston gear part #'s in addition to the amazon links in post #3. After a little time the links will probably become dead, so having the real info in the thread will help future readers be able source the parts easier.
Keep up the good work.:cheers:

What a screwed up post:willy_nilly:
Thanks Rob





Thanks Rob
I didnt think about that

I'll have to call Boston gear or a distributor to get part numbers and specs
All I have found is pdf catalogs and they aren't easy to navigate.
The drive gear shaft will most likely have to be made separate. It looks like it may have been special order or monarch fabricated.

20201225_143208.jpg
The shaft and gear are all one piece. pin is separate.
Suggestions on a source appreciated.

The bronze idler gear with 3/8 bore should be available.
Both gears are 35 teeth for these two gears

Ill get this gear stuff straight tomorrow
