    1910s W.P Davis lathe with odd size spindle

    Interesting, I just figured they were really worn out but it makes sense they’d undersize the spindle threads a little to prevent interference.

    W.P Davis Machine Co Lathe restoration

    I’m nearing the end of the restoration of a 1910s W.P Davis lathe and just wanted to share some pictures. The only thing left for me to clean up and repair is the headstock assembly I’ll post pics when it’s all together Here’s some before and after pics . Before: After:

    1910s W.P Davis lathe with odd size spindle

    I’ve double and triple checked that register diameter and it is indeed 1.5614 so .0011 (basically 1 thou) under 1 9/16 it’s still running concentric as far as I can measure (checked with a .0001” resolution rest indicator) and got little to no visible movement so I’ll just make any future...

    1910s W.P Davis lathe with odd size spindle

    I actually have a 4 jaw with a fitting backplate already (it came with the lathe) but I was looking to make a backplate for a precision buck chuck I got and I only just recently bothered to measure it. I’ll check concentricity and make sure that it’s still running true and if it is then I’ll...

    1910s W.P Davis lathe with odd size spindle

    Seems like I got pretty lucky to have it come with a face plate then cause I haven’t been able to find anything else related with a 1 9/16” 10tpi spindle

    1910s W.P Davis lathe with odd size spindle

    I didn’t know that. Is it 1 thou undersized as a clearance or just worn down by 1 thou?

    1910s W.P Davis lathe with odd size spindle

    I checked the threads on one of the backplates and there 10tpi

    1910s W.P Davis lathe with odd size spindle

    I have a pretty old line shaft driven W.P Davis lathe with an odd spindle size of 1.5614”. This just seems too far from any common spindle size to have worn to that Diameter and what I believe to be the original surface plate fits just fine with seemingly good fit so I’m not sure.

    Thank you! , I’ll be posting more detailed pics of it soon under antique machinery and history section of the forum I’ll link that at the end of the thread when I make that post.

    F.E Reed large change gear identification

    Hello everyone I did the measuring and some simple calculations and found that the gears are an 18DP and a 14.5 degree contact angle. I printed out some copies of what should be identical to the original, and they are! Mystery solved huge thanks to everyone for the help I look forward to...

    F.E Reed large change gear identification

    That’s I good idea although I’m beginning to lean towards the idea of just making an entirely new set with a diametral pitch of 20 for simplicity sake. I’m not not sure what I’m gonna do about the compound gear on the 2nd stud I think I’ll make a new 4 position thread chart where I get a...

    F.E Reed large change gear identification

    I’ll look around a bit on eBay or facebook marketplace for someone parting out an old lathe and see if I can grab some gears. Thanks again to everyone for the help

    F.E Reed large change gear identification

    Thanks to everyone for the info, next time I’m in the shop I’ll take some measurements do the calculations, put em in cad then print and compare to the old gears Fingers crossed 🤞 everything meshes correctly

    F.E Reed large change gear identification

    Also how would one go about determining the diametral pitch of the original gears?

    F.E Reed large change gear identification

    I only need enough gears for the more standard thread pitches like 8,10,24,32 tpi so somewhere around 8 gears

    F.E Reed large change gear identification

    If I were to remake an entirely new set of gears for threading what would be the important values I need to keep. Just tooth width/tooth height, tooth spacing and tooth count? (from the original thread chart)

    F.E Reed large change gear identification

    I suppose I should have been a little more clear in my original post my apologies but I still have 3 of the original gears a 28,96 and 112 tooth gear but I’ve been thinking and wondering if I only have 3 originals then I might as well just make a whole new set of change gears with more standard...

    F.E Reed large change gear identification

    I took a look at that book and it looks like it will have some pretty useful info. It’s even got gear profiles printed in scale for comparison to pre-made gears and some numbers and other info more relevant to the time period. Thanks for the recommendation!
