Easy part to make on a lathe. Does anyone here turn parts?
« on: March 06, 2018, 01:20:13 PM »
Hi, I posed this question on another thread, but I think it deserves its own.

Anybody run a lathe anymore?  I can make up three adapters to do this, but one-piece would be best.

There's a small turned part I need made, to complete a new rig I'm working on.

It's standard 5/8" spigot, with or without a 1/4"-20 stud on top, with 0.45" Spigot on the bottom to fit into the Windtech clamp's 0.47" holes.


Like this 5/8" spigot on the top.....

.....but the bottom half a smaller (0.45") spigot, to fit into a Windtech clamp.

Easy part to make on a lathe.  Red brass or free-running steel.  Does anyone here turn parts?

Hey K,

Just in case you can't find anyone-

I have a simple alternate idea which may or may not work for you- I generally use a stainless machine-bolt of the appropriate length and shaft diameter through the hole in the Windtech clamp.  With the bolt inserted and the hex-head up against the edge of the clamp, the Windtech knobbed set-screw locks it in place.  I then use the extended threaded portion as a stud (or thread it into something else).  A few times where I wanted to have the hex-head end of the bolt as a stud-shoulder on the extended portion (I think I was connecting to the stud socket on a Super-Clamp and a hex-head bolt fits in there perfectly), I used a longer bolt and secured it with nuts on either side of the Windtech in addition to the set-screw, leaving the head end of the bolt extended as a stud.  Apologies if this is obvious but undesirable or won't work for some reason.

Alternately, if the main section diameter of a standard spigot stud is small enough to will through the hole through a Windtech but the shoulder is not (I don't have a standard spigot stud here to measure to see if it's main shaft dia. is < 0.47") and you have a belt-sander available, you should be able to remove the shoulder from one end of the part you linked pretty easily.

Yeah, I guess I can price getting one of these,

and then figure the cost of getting the bottom end turned down to 0.45"

I'd rather put some money in a taper's pocket if I could.  Anybody got a lathe?

I hear that.  We have a machine shop but they are currently short-handed and long wait-listed, and my plant manager would probably kill me if I even asked.

Bump for a TS machinist.

Years ago I got together with a neighbor who had a machine shop and wanted to produce a replacement mount stud for the Windtech C clamp. He agreed to do it and quoted me a price of around $6 for an aluminum piece and $9 for brass. Seemed easier and cheaper to get a new clamp so I abandoned the idea.

Somewhat tangent to Gutbuckets lead,...
Is there a particular reason to stay with that 5/8-27 thread?

Have you tried to see how a 3/8-16 thread rod connector ferrule might fit in there?
A 3/8-16 thread rod ferrule cross-sectional wide profile comes really close to your specified dimension of .47", at its widest mark.  I'll dig out some calipers and see if I can get a better measure.

I use a whole series of adaptors made from this same thread pitch thread rod, with ferrule connectors and jam nuts.
The Manfrotto Mini allows these adaptors to pass through the clamp, lengthwise.  It has two set screw points, and, locks the adaptors securely. From what I see of the Windtech, it would have similar capabilities.

Nope, no use for the 1/4" or 3/8" thread stud at all, just need a 5/8 spigot to 0.45" spigot.

I'll get this one and turn one end down to 0.45" dia.

Stuck on stupid is I. Sorry.
I saw 5/8, and my mind added -27, and, it then started into this runaway thought about threads.

Capn — send me a drawing of what you want.  I’ve got an old Southbend and can probably crank it out in brass for you.  I did some Superclamp studs awhile back, came out OK.

Thanks mixedplate!  I ordered a couple of these double-ended cheapies.  I'll send you a PM in a week or so, to get your address and send them to you.

They'll need one end turned down to 0.45" dia.  I'll make a good bar napkin drawing.  Looks like they're made out of aluminum.



My grandmother outlived 5 men.....grampa #5 used to have a niiiice Southbend in the basement....made brass piece-parts at home on contract to Uncle Sam during WWII.

Wish it were ten years ago....I'd have made these by now...!  ;D :bigsmile:

Capn --  OK, just send them to me when convenient and I will turn them down for you.    But if aluminum is adequate for your use, and you don't need the threaded studs on the ends, I can just make a couple and send them to you if you shoot me a diagram with critical dimensions shown.

I guess it would be better if I have those threaded stud ends.  I got the pair ordered, standing by to send them off to you for mods soon.  Thanks!

Can you send me your address in a PM when you get the chance?
