Hi All,

Not sure if it is of interest to any or many, but this will be my last thread on this board.

It has been fun, well, when I wasn't being overly grumpy with first-time posters and their...

Not knowing the scale you are dealing with, nor whether a small amount of water is allowed to be purged in the process, I would suggest you look at a car's hydraulic breaking system. Been around for...

Hi Christian,

I know it is poor form to answer questions with questions, but posit...

Q:
Who gets to pay for remedial work if the County Building Inspector rejects the work?

Q:
Who is...

:D Thanks, but guilty -- it was a guess. Although, 784 seemed a random enough number of about the correct order to be believable.

My deepest apologies for forcing the groan and the Manager's...

If vapor is coming out of the hose under any sort of pressure, it suggests to me that you have a head gasket issue and gasses are being forced out of the cyclinder and into the coolant passages.

Only cadkey Help system could resolve that query for you.

PDF is generally a Vector-based item that can usually be converted to DXF. You should be looking to see if cadkey can read and write DXF....

I think the "99" should give a clue to vintage there. I seem to recall looking at it many many years back, or at least something similarly named. The fact that I do not recall it readily, strongly...

I guess at the extreme ends of technicality, the two bolt might be better than a single bolt as theoretically at some point the single bolt clamping pressure is at zero 180-deg from the bolt. However...

Dan, not uncommonly for first time posters, you have omitted some of the really important stuff. What are you putting on the mezzanine floor? Machinery, desks, people? How many or how much? What is...

Ha, funny you should mention the intern thing. I was coming in here this is morning thinking I would have to tread lightly with any further comments. Thinking more about it, it was sounding very much...

This is sounding to be quite a complex thing and not something that can be generalized about.

Are the spring ends in pockets at both ends?

Do they have to be compressed all at one time? I know...

Hi, interesting issue. As is so frequent here you have not supplied anywhere enough information.

The diameter and length of the springs.
The coils count and air gap between coils.
The...

Based on your stated current position in another post here, within the Engineering world that is a very risky statement to make when you know nothing of the actual situation.

The OP could...

It's called a "flatbed plotter," or "flatbed pen plotter". Been around for 30+ years. Internet search will reveal all.

Not sure about a Regulation, but certainly a professional Engineer's design for doing this is mandatory. IF you want to do it safely and not risk cracks in the welds during the lift, then an...

...and that's why I say do some research on what you are using and trying to do. Skipped steps is a bad thing and they cannot be made up or compensated for during a complete printing run.

If you...

As JB suggests, larger pulley on the motor means reduced torque so stay with a small (maybe 12T to 15T) on the motor. With efficient controllers (Gecko??) you should be able to peak at about...

Hi and welcome to the forum. The motors, I assume because of the "holding torque" statement, are stepper motors. You need to be more precise if you want to get any useful information. Stepper motors...

Hi L,

You may want to look at alternative methods than a friction clutch. It depends on what things are important. You have not stated weight, size, HP and a whole host of other things. Is it a...

Hi Seth,

Welcome to the forum. Just decide on a reasonable rotation in degrees and then use two arcs that will give the lift in that desired angular rotation. The fewer degrees the harder it...

daigoro,

In addition to all cautions and advice, please consider that because the thing stands and operated fine as it is, by raising it you will be adding serious extra loads to the structure. It...

Welcome to the forum and I kinda feel a little for you in your plight with the customer. :)

Hate to say it, but the description you have given is nowhere near enough information to offer an...

I especially appreciated the "urgent" part. I like that in a lazy, indigent incompetent.

C'mon guys, be a little kind.

Dale,

Curt, you need to buy a couple of books on alernate energy production. Way too big a subject for folk on a website to get you started.

Not sure why 30-seconds on and 30-seconds off is "desired,"...
