Hendey Refurbish #3

Bear, do you still sweep the two vises to fine tune the alignment or do you find that clamping to a bar is within a few tenths?

I didn't check it with an indicator yesterday... but since you asked, I ran an indicator on it this morning.

Across the full width of both vises, there is a total indicator movement of 0.002"... most of the movement is in the soft aluminum jaws on the blue vise.

Machining the 70 degree angle on the edges of the gibs is just for clearance, so two thousandths is more than 'good enough'.

I’ve just read through all three Hendy Lathe restoration threads - amazing work!

Am I correct in saying that you now have 5 Hendy lathes? One for each of the restoration threads, a donor Hendy you bought in this thread and a Hendy you already had? If so, you could start a Hendy museum and start charging an entry fee!

Thanks, Ben...

Yes, I have 5 Hendey lathes, two are 12 inch lathes and three are 14 inch... I may be nuts...

I've really enjoyed working on these machines... I've learned a lot tinkering with all of them.

I've finished painting the upper slide of the taper attachment...

...and this morning I finished the gibs for the upper slide...

I have been working toward getting the taper attachment finished and installed, and planned to have most of it done tomorrow. This morning I realized that I am getting WAY ahead of myself... I've skipped several mildly important steps...

I can't install the taper attachment until I install the pivot block that I machined earlier.

I can't install the pivot block until I install the cross slide lead screw.

I can't install the lead screw until I install the apron.

I can't install the apron until I install the gear rack under the bed.

To top all that off, I wasn't planning to install the apron until I move the lathe into it's permanent position, and I can't do that until I get the motor mount fabricated and installed. I don't yet have a plan for the motor mount... so I guess that is next...

Bear with me... I'll get it figured out eventually.

Ah, the gear rack bone is connected to the apron bone. The apron bone is connected to the lead screw bone, etc. Looks great!

Wow, a 24" long gib on your taper attachment?!? I'm curious what the travel is and how much angle can you dial in. I think my 14" x 40" has around 12" travel and probably just 5 deg.

According to the Hendey manual, it allows 14 inches of travel and an included angle of 15 degrees... I assume that would be 7½ degrees each direction?

Also according to the manual, you can use both longitudinal and cross feeds simultaneously to increase the taper angle significantly. I haven't exactly been able to wrap my head around that yet... but eventually I'll probably try to figure it out.

Thanks! I was curious because of a project I have in mind on my Clausing 5418. I've been contemplating making a taper attachment for it though it'd be a heck of a lot easier to find one on eBay. My worry (guess it'd be part of the design) is cross feed travel vs. longitudinal travel. I'd hate to design it with too much of an angle and run out of cross feed travel while making a cut.

Really going down the rabbit hole; I had a Rockwell 10 x 36 with a taper attachment that was sold 4 or 5 years ago. The one thing I miss about that lathe is the QCGB had a 27 tpi setting. I'd very occasionally thread pipe with it. Long story longer, my Grizzly G0709 has a taper attachment, but doesn't do 27 tpi, the Clausing has 27 tpi, but no taper attachment. A smarter person would cut a new quadrant gear to get the 27 tpi. I'm leaning toward that as cutting a gear is a lot easier / cheaper than buying/making a taper attachment.

Great work by the way! I love watching and learning from your threads!

I haven't worked on the lathe in a while... I've been working on the Arter carbide grinder, trying to catch up on yardwork, servicing vehicles, etc...

I'm still working on the plans for the motor mount plate also... I've almost got that figured out.

Yesterday, I started working on what I hope will eventually be the bed clamp for the taper attachment... the clamp was missing when I bought the lathe. I'm going to attempt to make one and try to keep it at least similar to the original.

Luckily, I have an original bed clamp on Hendey #2 that I can use as a pattern.

I started with the piece that actually clamps to the rear way. I've machined the 90 degree groove to fit the way...

My plan is to make this in five seperate pieces and weld them all together.

This may take a while... bear with me.

I've been working on the clamp... I cut another piece of 1018 and drilled a 33/64 hole through the center and cleaned up both ends. Then I set the first piece up on the vertical mill and used a boring head to cut a notch in the side of it to fit the second piece, then welded the two together to finish the way end of the clamp...

I did have to mill a 45 on one side of the second piece to clear the angle in the first piece.

I've started on the piece that fits over the threaded rod on the taper attachment... it has to be clearance for the 3/4" rod. I've drilled it to 5/8", but will have to finish the bore with a boring bar... I don't have a drill the right size.

The middle section that connects the two ends will be cut from 1/4" plate... I'll have to see if I have any 1/4"... I may have to buy a piece.
