Speed Control and Frightening Noises

dusty · Post by **dusty** » Tue Jan 02, 2007 6:37 pm

Nick:

Thank you so much for the last two posts to this thread. They are very informative and they communicate very well; the addition of 'modern day photographs' makes them very effective.

While these posts do not add any new information, the detail provided by the photos make the procedures much easier to follow. This is especially true if the technician doing the work lacks some confidence.

I have resolved my screeching noise problem and once again have lubricated the sheaves. This time in accordance with the most current instructions that I have.

I can hardly wait to see the latest maintenance manual. I trust that the current Traveling Academy classes will have all of the up-to-date information.

This post caused me to do some research; I was certain that 1-2 drops of oil to the sheaves was per instruction and I am correct.

I am correct unless I want to also be current. The instructions available on line ('MKVMaintenance_1_10.pdf') recommend 2-5 drops and now this posting recommends 5-6 drops.

Incidently, when SS determines that past instructions are no longer current/correct, how is that information passed on to current users. If it doesn't already exist, I would like to recommend that a bulletin board be established on the official Shopsmith website (Shopsmith.com) where the changes can be found in realtime or that change notices be sent to all registered users via email. The mechanism being used to notify us of 'special sales offerings' works great - just expand it to include 'special notices'.

Nick:
I agree with Dustywoodworker, your posts are great and I might add a lot easier to understand then the instructions that were sent to adjust the speed. I'll be rechecking my speed adjustment tomorrow. Your help is greatly appreciated. Dustywoodworker, I think you had some good suggestions.

Dusty, you're implying that my posts have more weight than they really do. Just so everyone here understands where my posts fit in the scheme of things, let me paint some parallel lines between what I am doing and the Federal Aviation Administration -- FAA. (I promise, your Honor, that I will make a relevant point if you'll just let me ramble on for a bit.)

The FAA has put in place several programs by which pilots can share timely information. Two of them come to mind. (1) From time to time, FAA engineers and maintenance specialists consider new information that has come to light about an airplane or an engine, they decide in committee that this information is crucial to safe operation, and they issue an official Airworthiness Directive (AD) carrying with it the legal obligation for mandatory compliance. (2) In another program, the FAA solicits timely information from pilots in the air and relays these pilot reports or "PIREPs" to other pilots enroute. PIREPs do not carry the weight of officialdom; they are not even reviewed by the FAA for accuracy. They are simply passed on. (For you history buffs, the PIREP program is very similar to reports posted by riverboat pilots on the Mississippi 150 years ago.)

The information posted on this forum and others like it are PIREPs, not ADs. We are Shopsmith pilots sharing information, not an engineering committee issuing proclamations. When you folks have questions, I file them away in the back of my head until I have time to wander out on the factory floor and ask someone with a little experience in the matter. There are people here who have built and rebuilt more Shopsmith machines than we will even see and I figure this expertise is valuable to all of us. But it's not passed by Shopsmith's Engineering Committee; I don't have time to check it against every manual Shopsmith has issued over the last 60 years; and I don't have the authority to send it off to the traveling academy instructors with the understanding that what I say is Shopsmith's Official Word on the subject.

I'm just a teacher here, folks. What I do is informally obtain infomation from people who know and informally pass it on to people who need it. Nothing more than that. When I am promoted to Oracle of Shopsmith, there will be a formal announcement and you will all be required to sacrafice a goat before I answer a question.

With all good wishes,

The confusion is your signature, when I use my Intel email address to respond to a forum on computers I add a disclaimer that anything I say is my opinion and not endorsed by Intel. When I respond in my official capacity I sign with my title (as you do).

I think it helps, use the information as you wish.

I don't care all that much what title is included in the signature block; what impresses me is the quality and reliability of the comments above the signature.

I have read all of your postings, many several times over, and I am very much satisfied that if you posted it, we can rely upon it. I really don't care whether the engineering review board has given their total blessing or not. It is not the engineers who come face to face each and every day with the customer and all of our varied problems. On the other hand, the entire training staff and the fine folks in customer service do.

Therefore, I shall continue to ask my questions and will eagerly look forward to the comments that I read in response to them and to all of the other very interesting and informative posts that I find on this forum.

The Shopsmith engineering staff has produced a fine set of machines but we wouldn't know that if it wasn't for the rest of the staff who meet our needs each and every day.

Nick,

This is tremendous info. And your pictures very clearly show what you are talking about.

Thanks,
Hal

nick: been have a time trying to adjust speed control dial. looking at ur post of o1-o2-o7 . am i correct in seeing on fast speed the belt is 1/8 below rim. mine is when on low speed what did i screw up. mostly all i have been doing is lathe work. runs great, i keep it well maintained. after a long session always clean her up inside and out . when i bought it used kust a few short months ago speed control was stripped out other wise run out nicely. thanks. Papahammer8 jim to all the saw dust junkies on the forum.

If you follow the procedures in the following post, you should have proper belt alignment and good speed control.

If you open the peep hole and watch (keep the fingers out of the way)
while you run the speed up and down you'll see how the belt changes position on the pulley. What you are watching is the pulley ratio be changed to facilitate speed change.

thanks Dusty have followed Nicks instuctions . but a lil confusing. is the high speed position at the top of sheave rim or is it the low speed.

At high speed (5200rpm) the belt should be just below the edge (1/8" or so) of the adjustable sheave.

Have you opened it where you could see the sheave and adjusted the speed (remember, with power on) and watched the belt travel up and down on the sheave as the speed is changed?
