Best advice to a new grad is to take a job with either a smaller company, or a small division of a larger company. Generally super experience, as mentioned,...

Not sure who that was "aimed at".

My swivel vise cost me about $5 and some work. The swivel base I made, meaning that I got just...

[J Tiers]

Let it go, Brian.

I do not NEED nor WANT to search this thread. I doubt if anyone does....

[J Tiers]

Nice.... I like it.

A question: Why did you go with the chain over a belt drive? Is it also used as a positioner?

[J Tiers]

So now a swivel base is the next "marker" indicating that someone is "not one of the cool people"? That they are "just a clueless...

[J Tiers]

Of course not.

On the other hand, if one pays the going rate, as opposed to a premium, one has more left over to use for something else they...

[J Tiers]

No doubt. But I am at about 38 deg N Latitude. You are up at 60 deg or more N Latitude....

I have a mill on which the overarm support has been brazed, as has at least one dovetail. it works fine. Brazing the banjo should not be an issue per...

[J Tiers]

Well, maybe.

It can be damping, but it can also be "stiffness". Stiffness RAISES the vibrational frequency, which can be good,...

The gear on the spindle is not integral, and is obtainable.

You appear to have around a dozen gears, out of the 17. Logan gears are around...

[J Tiers]

There are other controllers for DC motors other than the ones originally supplied with the treadmills. The other ones may be more suited to the purpose...

[J Tiers]

Actually, I originally though that looked pretty odd myself. But as I looked more at it, I got to thinking about how I would hold that on a milling...

[J Tiers]

Nope, not an SB, it is a Logan, the Wards version of the Model 200. A very nice machine, actually, and I like the drive on that better than the "patent...

[J Tiers]

Usually, that sort of overload is "self-resetting". Those particular ones might be "one shot" types, of course.

[J Tiers]

Well yes I can. I own one....

[J Tiers]

My take on it is that it is mixed. The reasoning is as follows:

The forces are "contained" to some degree in the "path"...
