Thanks Pete, looks like that would work if I had more room but I can't get inside once the thumb screw is in place.pete wrote: ↑Thu Apr 30, 2020 7:57 pm Edit https://www.mscdirect.com/FlyerView?pag ... s/big-book 18-8 stainless at least with just a quick search of the MSC catalog.
I'm still thinking that nylon insert is the best idea so far. From my tests it appears to be holding well. Time will tell.

Dang! I thought I was bad about coming up with complex solutions to simple problems! LOL

Re: loose screw issue
This thread reminds me so much of conversations with my son.
Me: I need to make this part and it's going to be a pain to hold it.
Son: Why don't you just clamp it here?
Me: Because when I get to that operation, that surface will be gone.
Son: You could machine a fixture to hold it.
Me: It's a single item and it was supposed to be a quick fix and move on.
Son: If you redesign the whole thing with some surfaces that could be used to hold it, you wouldn't need a fixture.
Me: It has to fit in an already existing space so redesign isn't possible.
Son: What if you modify the existing space?
...ad nauseam
LOL
The original part reminds me so much of the things I make, too. I seem to put so many constraints on my projects. Must be easy to make, fast to produce, last forever, not cost much, be worth way more, and most important, it has to look cool/gadgety!

It reminds me of a very common type of "minor" engineering project:
"Fix this but don't change anything."

Like a lock nut, but in reverse. Could maybe work if the hole is blind and preload is set by screw shoulder. Tighten outer to set preload, tighten inner to lock in place. Or along the same lines, like a split nut used to minimize backlash, but a screw, and remove all clearance, thus "jamb" the screw.
Again, I make no claims to practicality, just something that popped into my head while browsing.
This is not a bad idea!
I have a "Cutter Master" cutter grinder that I have been giving some needed attention. It has micrometer stops for the table.
Here are a couple of pictures of it, disassembled and partially assembled.
From left to right.....Grub screw, Dial, Wave washers, Threaded shaft, and Center w/ key slot.
Top...Collar and Base.
The Grub Screw is used to attach the Dial onto the end of the Threaded Shaft creating a solid assembly. The Wave washers are for setting the amount of tension, required to advance the Center. They push up against the end of the Collar. You would not need the Wave washers, as you are using the friction from Thumb screw to Shaft to set the tension. To make is tool free and pretty, one would only need to make a two part Thumb Screw. Tighten the fist part for tension and the second part to lock it. One could get tricky and make the two parts of the Thumb screw. captured to each other. making them harder to lose in a steam.
It only adds one part to the whole assembly.
This will not help you, using up your existing inventory, but hey!
Live for the moment!
Prepare for tomorrow!

Re: loose screw issue
Thanks Patio!
I like that idea a lot....I could possible make some mods to incorporate that. I have been thinking that in order to move forward I may just have to abandon my inventory and start fresh, this could be an idea worth investigating.
