I spent a lot of time and put a lot of thought in responding to this thread only to have my reply vanish when I tried to submit it. Apparently this sight is only letting short, sarcastic, and nonconstructive responses to get posted.

I see none of the type of responses you mention here.

no personal offence intended. I was just venting my frustration over loosing a lengthy, and hopefully a constructive response.

No offense taken, since I'm as guilty as anyone about short snide comments.

There was a glitch, and a response regarding this loss of longer, detailed posts.

Not sure of the outcome, but the temp fix seems to be to copy longer responses to the clipboard for safety.

Maybe Savvy Exacta can refresh our memories.

welcome to the club, that happens all too frequently.......usually after a well thought out reponse

I've had that happen too.

I don't know what causes it, but I now use the highlight/ copy function, before attempting to submit. If it disappears, I just open a new response window, paste, and submit. It seems to have something to do with the length of time that the response window is open...so the lengthy, well thought out posts are the most likely to disappear.

For any lengthy entry, I do the original either in a word processor or in my CAD program, then copy and paste into the CR4 editor.

Yes, although if the WP is MS WORD, it might be clearer if stated as "drag". "Highlight the entry in the word processer, place the mouse over this, push the left mouse and drag it over to a fresh blank comment box". This is from my experience doing basically the same that you do. If the WP is highlighted and copied it will not paste to the CR$ comment box. This was a "speed bump" in my search to a workable solution to the time delay problem.

As with you probably, it is a great time saver and you get a sense of accomplishment when you work it out!

Since I'm a long-time Mac user (very close to 30 years), there are slight differences. I do use MS Word occasionally, and I'm using it right now, but I've never gotten used to a Right and Left button. I work almost entirely on a laptop, and nearly always use a trackpad; my right index finger is the pointer, and my right thumb clicks the button on the right side. My left hand is thus available to press Shift, Option, etc. as needed. It would be very inconvenient for me to use the left side button with my right thumb, so I have my preferences set so there is effectively only one button, which of course acts as the left button. If I need to right-click something, I use Option-Click.

I do drag to select text and other items, but in this case I would use Command-A (Control-A on a PC) to select all, Command-C to copy the selection to the Clipboard, then go to the CR4 editor and Command-V to paste the selection into the editor. I don't recall ever having any difficulty pasting into the CR4 editor.

One other item that might influence the procedures is the choice of browser. I currently use Firefox. Safari is the default browser on Macs, but the CR4 toolbar

does not appear in Safari, so I don't use it. I haven't tried Chrome.----

I just pasted the above from Word. More in a second post...

I posted my previous post last night, but this morning it did not show, so I just posted it a second time, adding a minimum to the Word text to save time. I closed the window and then returned, and the new post does show. I'm now typing directly in the CR4 editor window.

As you can see, although all the text from Word pasted correctly, the graphic (a partial screen shot of the CR4 Toolbar) did not. The original paste from Word appeared in a serif font (the Word default), but the preview changed it to CR4's standard sans-serif font.

There does appear to be a rather short time limit on posting/editing...

In reading you last answer, as you and I have already stated, we both notice there are many ways that things can be done. I now understand more about the problems you are having with the posting. As with many of the contributors, and myself included, we sometimes tend to associate the posting with our own particulars and not the general or specifics of the posting. This is a constant problem with this type of forum and many of the users but enough of that for now. That is something that can only be discussed in a very great amount of time and I don't think you are interested, as I am not, discussing that tangential subject at this time.

I cited the process I did because I didn't know what you had a Mac. A majority of people use "IBM" based PC's, probably the most used word processor (wp) is Microsoft Word (although there are many wp's that can be used with this forum), and I am most familiar with these units and this wp. In this approach I guess you could say I am the "averagely" equipped user. Sorry if my approach was wrong. I went to the "average" question and answer concept.

There are many, probably many more than you and I realize, CR4 members that have the same problem. The time limit is very frustrating and sometimes counter productive to good and clear answers.

Now to further confuse you and anyone else who is interested in handling the time limit and working with it consider this: Although my right hand is my predominate hand and the one which I write with, I mouse with my left hand. Got into this because for me it is easier to type with both hands, then use my right hand to write or use an adding machine or any other device. This way I don't have to let loose of the mouse, use the other device with my right hand, and then put my right hand back on the keyboard. Especially when writing, this is easier for me since I don't have to let loose of the mouse, pick up the pen/pencil, write, put down the pencil, grab the mouse with my fingers in the proper position and then get back to keyboarding. The left hand also acts as a reference to the location of the keyboard. Same with several other ergonomically compounded motions. Now combine that with I don't have the mouse buttons reversed, as left-handers would probably do, index on right and middle on left. Now combine all these with the "Natural" position keyboard (left keys are split from right keys at the center of the keyboard at an approx. 15^o angle) and there is another deviation from average. Now finally, my keyboarding skills are real lousy! The last time I had any keyboarding training was when the names like Smith-Corona and Royal typewriters were the best names for keyboard equipped devices. That was before the development of the work "keyboarding! The IBM "ball" hadn't been introduced yet.

Hopefully my other skills far exceed my keyboarding and mouse skills. I can say that my first programming skills were with Fortran 2 and 4 on a IBM 1130 and I was pretty good at that.

What does all this mean? As an analogy-- "We are both pounding the stake into the ground. Your using a 3# drilling hammer and I'm using a 48 oz. Ball Peen hammer". We are both working on the same problem but with different tools working for the same results.

If you develop a better way to get around the problem, either for mac, PC, or both, please let everyone know. Its a real pain in the A_SS!

Thanks,

Gee, you know, of course it could be improved - the point was to get him to do a little work on his own. Providing IDEAS which lead to creative thought are better than actually giving the answer as if it was contracted to design. My drawing was intended to provoke discussion from him, and maybe in the process of an exchange of questions and answers he would learn something of mechanical design. For the record, I could have provided the blueprints of the design that the drawing was loosely based on, but thought if he were mentored he would be better off in the long run doing his own stuff rather than being spoon fed. ( no offense intended, and none taken )

For starters, the reverse threaded rod and nut are not common and make the assembly more complex than it need be.

Second, the range of motion being considered in the design would have the scissor elements long enough so they would not be prone to the cantilever effect, I never suggested the scissors be exercised to their limits. there's other reasons for the design as shown, but they were supposed to come out as a learning environment.

Yes, you're right!

On the other hand, there's still a lot of information missing to actually build a stable and reliable unit, such as the sizes of everything, pitches of thread, sizes of pulleys/sprockets, etc.

I don't recall if the OP said anything about size, how far it needed to lift, how fast, with how much effort, etc.

20Kg, but no range, I expect it is a lift table for a small child and the gearing would be suitable for the average person strength by hand crank as specified "person turns handle". You are also right the lift distance has a large bearing ( pun intended ) on the design elements. Given the mass of "only" 20Kg its likely to be a smallish device.

No mention of any holding or braking mechanism either.

that would be another lesson in adequately describing a design problem.

the rollers could be drawer slides too, a captive bearing and eliminates some of the stability issues too

I did not bother with problem 2 because I could not grasp the idea. Simply the description does not make sense to me. I dont care whose idea or project it is, there has to be enough information to make an intelligent response. Otherwise I might just imagine that you do not want your professor to know you posted his problem on this site LOL
