Hello DoN. Nichols,

Thanks!!! _ I was pretty sure the string went through the bolt (as opposed
to the nut) but wanted to be sure...
Why do I want the webpage? - I like to give credit for where I borrow ideas
- simple as that. When I write up this project, I'd like to be able to point
out this little tip and say where I got it from.. right now I can say it
came courtesy of the folks at RCM, but it'd be nice to say where else it
came from.

The machine jacks will be used to set a sine bar because until I have sets
of guage blocks, etc, machine jacks set to a vernier caliper will be better
than nothing.

Thanks,
Des

G'Day,

I recall seeing a webpage where there was some pictures of a threaded
device which used a piece of weedwhacker string pressed through a
hole to serves as a form of threadlock - similar to a nylock.

Now I need something like that in my design, and I don't recall the
website.
Does anyone know the website page I'm describing?
What is the URL?
I don't remember a website -- but I do remember posting here the
advice to another regular's question the suggestion that he try that
technique. I've seen commercial screws with such inserts, and when
I've
needed a locking feature in existing screws, I've used the technique.
I
simply would find some nylon string of a reasonable size for the screw
size, drill a hole perhaps between 1/2 and 3/4 the diameter of the
screw, shove in the nylon, and cut it off flush with the crest of the
threads. For really small nylon string -- try either fishing line
(leader perhaps) or Classical guitar strings.
For somewhat larger -- aside from weed whacker strings, you might get
some scraps from a place which restrings tennis rackets.

The other regular tried that, and it did what he needed.

Why do you need a web page to do this? Just do it. :-)

I'm making up some little machine jacks for settign a sinebar, and
they tend to move a littel when they are maneuvered into position,
I'd prefer the thread lock action as opposed to the bulk of a lock
nut.

Setting a sinebar on jacks? How do you get the precision you
want? Normally, I use a stack of cheap Chinese gauge blocks -- though
I
might try an adjustable parallel if I needed a variable which I would
set to a given dimension (usually using a micrometer). I certainly
would not use machine jacks.
Enjoy,
DoN.
