Dimension requests and more information
Hey all,
Thank you for your help getting this lathe back together!
I am Deg's friend that picked up the lathe and I am currently working on machining the missing cross slide sleeve before I bring it up to him tomorrow.
Here is a picture of our carriage where the cross slide screw sleeve mounts.
Here are two pictures of where I am at so far that show the front and back of the sleeve.
I have shoulders on the front and back to accept the dial back plate (1.187 dia and 0.875 long) and to locate itself in the carriage casting (1.125 dia and 1.125 long of which 0.375 will be used up by a flange i am also locating on the same shoulder).
I have a groove cut in the front of it to accept the bronze dowel pin that the dial backing plate set screw engages.
I have bronze bushings pressed into both ends of it that i still need to open up to the shaft OD of 0.6875 plus a little clearance.
From the front of the carriage, I have settled on a protrusion of 4.250 which i hope someone might be able to confirm for me.
I am starting to fabricate a flange now.
My plan is to start with a piece of .375 x 3" bar stock bandsaw cut and finished to 1.500 tall in the 4 jaw (no functional mill for me).
I intend to center bore an id of 1.125 to slide it onto the back reduced diameter of the sleeve to locate it. Note that this still leaves .750 of the sleeve sticking thru to locate into the machined hole in the carriage.
Next I am going to attempt to drill and counter bore the two holes for the socket head cap screws that retain it to the carriage. I don't have great location measurements on those yet. It looks like the bolt circle diameter is 2", but I haven't figured out a clean way to measure the clocking of the two holes. I know they are diametrically opposed, but I haven't established their height above/below the center line of the shaft.
The machine is disassembled inside my enclosed service truck for transport and I didn't stack things in a way that is conducive to accessing this feature to measure the situation better.
Then I thought I would slide it onto the sleeve and weld the two parts together.
I then plan to turn a 3" diameter on the two 1.5" tall edges of the bar so the flange clears the cross slide dovetails.
Lastly I will true up the rear face of the flange in the lathe to be normal to the axis of the sleeve and clean up the front face to make my weld disappear.
If any of this sounds wrong or dumb please let me know!

A Hendey oddity is that the whole shaft moves back and forth with the cross slide screw during taper attachment use - this naturally displaces the sort of clamped on cross slide dial
Hey Johnoder, Thanks for tying Deg's other post to this one, if that was your intent. It does have some pictures of his soon to be lathe in its current state.
I was studying the same manual you linked last night, and while very close it is not the same as the lathe we are working on. In the linked breakdown it shows the cross slide sleeve threading into the front of the carriage. This lathe has two tapped holes and and a grease impression where there was a flange on the back of this sleeve. I was able to find some pictures online to verify that both types were made by Hendey. I never found a parts breakdown showing the flanged style sleeve though.
You seem to be missing quite a bit actually, there is a small gear that is on that shaft, that is it's power feed supply, the main collar you are talking about, and the dial that tells you how much you have moved. I can luckily say that I have those parts currently off of my Hendey lathe and can measure them and give you blueprints or you can get original blueprint copies (possibly original parts) from HendeyMan.
Thanks GreaseGirl,
Could you confirm how far out the sleeve protrudes from the carriage on your machine?
That would help me a lot to know that my part will allow the correct travel of the cross slide and that the dial ends up in the correct place.
The rest of the parts you mentioned are in hand. You can barely see the feed gear installed inside the casting where it would mesh to the apron drive gear below. I have the dial backing plate and the dial. I also have the handwheel.
All of these parts were in the chip tray when I inspected and picked up the machine. The only part that I never saw nor could locate is the sleeve that spaces the dial away from the carriage to allow more movement of the cross slide outwards.
Deg,
Not sure what your missing but the cross feed screw should not be hanging out that far. Perhaps it's just needing the cross slide moved back or the screw pushed in. It may have to do with the taper attachment being incorrectly engaged. Looks like both pieces are off, the actual dial and the part that would have the witness mark which may be all that's missing. Nice score.

Thanks spaeth,
I am fairly certain the only piece we dont have is the sleeve that holds the dial backing plate away from the carriage. I am trying to machine it currently, and i am hoping you folks could verify that i am on the right track with my protrusion length and the bushing locations.
Any suggestions,feedback, or criticism would be greatly appreciated!
Thanks- Cody
