Save Time. Save Money.

Time is a commodity maintenance personnel typically have in short supply. We hear quite often, in our on-site Shaft Alignment Best Practices training classes, “………. doesn’t give us enough time for a proper shaft alignment”. So how can maintenance personnel get more time for shaft alignment? Stop wasting it! I had the pleasure of working […]

Shim Safety

| |

By on September 1, 2016

We recently received a customer request about shim safety.  An employee at the customer site had experienced a “near miss” safety issue due to walking too closely to a machine, and getting their clothes caught against a shim.  Since I have a scar on my right thumb caused by a 3 mil shim, I thought […]

Short-cuts, a way to make Precision Shaft Alignment take longer.

| | | | |

By on February 12, 2016

I love my job, I love conducting precision shaft alignment training at various facilities across this great country and interacting with industrial maintenance technicians that have suffered through or are suffering through the same issues I did. I love proving over and over again that the VibrAlign method of precision shaft alignment is the best […]

Soft Foot And The Dirt That Causes It

By on January 15, 2015

While on the road for VibrAlign ReAligning America, we trainers encounter similar issues at every facility where we conduct our Shaft Alignment Best Practices Training. During our training classes we ask the students what are some of the “pains” that they have regarding the precision shaft alignments that they have attempted in the past. The […]

Don’t Overlook “Hidden Shims” Under the Feet!

| | |

By on August 15, 2014

A recent Fixturlaser EVO class performed an alignment check on a 35HP, 1750 RPM electric motor and chill water pump set. The initial set of alignment results indicated horrible angular misalignment (14 to 16 times tolerance) and offset misalignment (6 to 8 times tolerance) in the vertical and horizontal planes. Before making corrections, pre-alignment checks […]

Why Do People Struggle with Alignment? – Part 2

| | |

By on March 26, 2014

In my previous blog entry “Why do people struggle with alignment? Part 1”, we discussed the importance of not only micing, cleaning, and consolidating shims but also noting the total amount of shims under each foot of the movable machine. The motor-pump set we performed an alignment check on, had the following amount of shims […]

Why do people struggle with alignment? Part 1

| | |

By on March 6, 2014

After a shaft alignment check, if it’s out of tolerance, some maintenance personnel will skip the pre-alignment checks and proceed directly to correcting the vertical and horizontal misalignment. Frustration begins to set in as the alignment results go back and forth and seem inconsistent. The laser shaft alignment instrument says to add 20 mils to the […]

“MIC” Your Shims!

| | | | |

By on September 20, 2013

Has this ever happened to you? You’re aligning a machine and your laser alignment system or dial indicator calculations tell you to add shims under the motor feet. You do what is expected, re-measure and you still have to add shims! Wonder why?  I’ve heard it before, my laser doesn’t work or you calculated wrong. […]

Sof Shoe® Shims

| | | |

By on June 5, 2013

Soft foot is undoubtedly the number one challenge faced on an everyday basis in precision shaft alignment.  The concept is simple enough; make sure the machine feet rest flat on the base. Unfortunately, it is not always so simple to solve. Before sitting down to write this, I noted there are 17 articles posted on […]

What Size Shims Should I Use?

| | |

By on May 16, 2013

One of my co-workers recently fielded a call from a customer, asking, “What is the proper way to size shims under motor feet?”  In other words, if the foot is 6 by 4 inches square, how big should the shim be? Excellent question!  And one I wasn’t sure how to answer.  I have always tried […]

Shims 201 – The Importance of Measuring Shim Thickness

| | | | | |

By on March 28, 2013

Stainless steel shims are now the standard for use in shimming machinery when preforming a precision laser or dial indicator shaft alignment.  They are clean, corrosion resistant, flat, and most importantly, pre-cut.  Their use speeds up the alignment process significantly.  However, it is very important to measure the thickness of a shim before using it. […]

SHIMS 102 – The pitfalls of carbon steel shims.

| |

By on February 21, 2013

Stan’s “Shims 101” blog last year provided some great guidelines and reasons for using pre-cut Stainless Steel Shims.  We repeatedly see rotating equipment that is supplied with carbon steel shims under the feet and/or shims of the incorrect size. When aligning machinery with carbon steel shims get rid of them! Measure the old shim thickness […]

Cutting Shims to Correct Soft Foot During A Shaft Alignment

| |

By on August 20, 2012

Here’s a thought-provoking question for you my fellow shaft aligners: is cutting shims to correct soft foot overkill? That concern was addressed last week during a shaft alignment training class where we aligned a nice little water pump. The motor had one of the stamped out bases that are always fun to work with. We […]

Shims 101

|

By on June 9, 2012

Stainless steel shims have for the most part replaced cutting shims from rolled stock. They speed up the alignment process dramatically. They usually assure a more accurate alignment since they come in many different thicknesses. They are clean, flat, and their thickness is marked on each shim. Since they are stainless steel, they are not […]
