181 Game Changer Conversions

Vandergriff 181 Game Changer Conversion.

Vandergriff Inc has led the industry in the move to narrower saw spacings and gin stand conversions. The first 181 conversion was done by A.L. Vandergriff at Elbow Gin in Visalia, CA in 1996.  Since then, we have developed a "game changer," rib, and worked with Namoi Co-op in Australia to convert over 30 161 gin stands to 181's.

In 2014, we converted 2 Continental 161 Gin Stands to 181's at Moseley's Gin and Whse. in Abbeville, AL.  These gin stands have run trouble free for 2 seasons now, and can easily gin at 22 BPH.

Not just anyone can "convert" gin stands. Some are finding this out right now. It requires precision machine work on the rib rail.  This same rail has to be installed properly.  Any sloppy work in this area, and the conversion is just not going to gin like it should. Finally, we have our game changer rib.  It is CNC machined from Domestic 1018 closed die steel forging (not inferior Chinese steel) and simply can not be duplicated by the competition.  It is strong. It is accurate. It will hold up to the stresses and strains 200 HP and higher motors will apply to them. They will not lose little seed. The profile change promotes better seed discharge, which keeps the roll looser and allows you to go on up with capacity.

 "I had Vandergriff Inc. convert 2 of my 161 Gin Stands. They have run for 2 seasons now averaging 20 BPH. I have had no issues with these conversions.  One of the best things I have done to my gin plant was to do this."  Ed Berry. Moseley's Gin and Whse.  334-585-2345

At this writing, there could be even more exciting news about Vandergriff 181 Conversions. Stay tuned.

Any questions about about our conversion,  call Ed Berry at Moseley's Gin and Whse. He has run 2 conversions for 2 seasons now with NO issues except increased capacity.

Vandergriff Ribs For Consolidated Stands.

We are now offerering a Vandergriff Rib for Consolidated 164/198/184/ and 222 saw gin stands.

The production process to get this rib made is exactly like we use on all other Vandergriff Gin Ribs.  Ribs are machined from 1018 Steel.  They are accurate from rib to rib.  No loss of little seed.  No nagging troubles.  We continue to hear stories of how bad their 184 and 222 rib performed.  We are here to step in with a quality rib to fill this void.  These stands are a "Product of Vandergriff Research."  Its only right we offer a Vandergriff Rib for you to install in it.

How to change out Wearplates in Vandy Gin Rib.

This is a short video on how to easily and safely change out wearplates.
Take the breast off and lay it out wearplates using punch. Then turn over breast like in video to replace or turn-round the wearplate.  This is the safest, and most efficient way to do this.  The area where the wearplate is located is the weakest on the rib due to the notch that is cut out to install the wearplate.  Banging hard in this area is dangerous.

The Move Towards Narrower Saw Spacings.

The Move to Wider Gin Stands and Narrower Saw Spacings.
Updated. May 2015

A current trend in cotton ginning today is the movement towards wider gin stands, and in many cases narrower saw spacings.  This of course was started in 1992 with the introduction of the Consolidated 198 saw gin stand, “A Product of Vandergriff Research.”  It was the world’s first 20 bale per hour stand.  It took well over 10 years for the rest of the industry to catch up and buy-in to the concept of bigger gin stands. Continental followed with its 201 saw gin stand and then Cherokee with its massive 244 Magnum. In 2009, Consolidated Cotton Gin Company came out with their 222 saw gin stand, also a “Product of Vandergriff Research,” but there was one key difference that differentiated this stand from the rest of the field. This was not an extension or addition to the width of the gin stand itself, it was a narrowing of the saw spacing’s in the existing 198 frame to ultimately get to 222 saws.    
Mr. Vandergriff had suggested this to Consolidated in the late 1990’s providing sketches and drawings with the proper, well calculated saw spacing’s to ultimately get to the final 222 saws. He even labeled it, “The 222.” All of this was based on his research at Elbow Gin on further narrowing saw spacing’s from what was standard at the time on the Continental161, Lummus 170, and Consolidated 164 and 198. So, Mr. Vandergriff wanted to push the envelope even further, and make the spacing ever narrower. He did exactly this by converting a Continental Gin Stand to182 saws at Elbow Gin in Visalia, California for the 1996 ginning season. This stand ran for close to 10 years in relative obscurity, drawing little attention from the cotton gin manufacturers,  so it was very interesting for Vandergriff Inc. to hear that 4 Consolidated 222’s had been installed at Lubbock Cotton Grower’s Co-op Gin for the start of the 2009 gin season.  Mr. Vandergriff passed away in 2004 at the age of 93. He had no idea his proposal for the Consolidated 222 would ever be considered, much less implemented.  Putting the "222 and 184" saw gin into production was indeed a surprise to Vandergriff Inc.  This would have never happened without Mr. Vandergriff's research, testing and implementation of the concept. Not to mention key drawings labeled "Product of Vandergriff Research."
Mr. Vandergriff has been such a seminal figure in gin stand development, and has played such a vital role, I feel that people in the industry would find his involvement very interesting.  I have pulled information from his archives and from his book, “Ginning Cotton, An Entrepreneur’s Story,” published in 1997 by Texas Tech University. All information is well documented in this article.   Of course, I have had countless hours of discussion with my father on gin stand development as well as other aspects of ginning over the years.
The Move To Narrower Saw Spacing in a Cotton Gin Stand.
Initial work on this concept started at Lummus with the Super 88 saw gin introduced in the mid 1950’s. In 1970, at J.G. Boswell Company in Corcoran, CA., he converted a Continental 119 saw gin to a 141 saws taking the saw spacing to unheard of spacings for the time. Why did he do this? To increase capacity of the stand and enhance the cleaning of the seed.   A representative from Continental Gin Company flew out and watched the stand run during testing.  There was a significant increase in capacity of the gin stand. This same representative flew back to Prattville, Alabama and it wasn’t long before Continental was marketing their NEW 141 saw gin stand.  Lummus quickly followed suit moving from their 128 saw gin to their new 158 saw gin stand using the same spacing’s as the 141.  In the late 1970’s he signed a consulting agreement with Continental to work on the incorporation of a seed tube and to continue his work in the area of narrower saw spacing’s.  Much of the research from this had already started at Elbow Gin in Visalia, CA where he initially converted a Continental 120 saw gin stand to 152 saws and had installed seed tube arrangements in these same stands.  He suggested to Continental the use of narrower saw spacing’s (161) and also suggested they modify their rib to improve seed discharge. At the end of 1978, he terminated his consulting arrangement with Continental because he felt certain stipulations in their agreement were not being honored.  Continental continued on with their work and this ultimately led to the Continental 161 Golden Eagle Gin Stand. The research at Elbow gin was the template for the development of the Consolidated 164 saw gin stand, the first complete new gin stand since the Continental 16” saw introduced in 1961 while Mr. Vandergriff was President.  These saw spacing’s , would be the same ones he had suggested to Continental Gin Company.  Soon after, Lummus followed suit with their 170 saw gin stand.  It is not a coincidence that all the saw spacing’s were the same as Elbow Gin, Continental and Consolidated.
Implementation of Narrower Saw Spacings.
At this time, almost everyone in the industry felt that it would not be feasible to narrow these spacing’s any more. But in 1995 he began toying with the idea of taking these spacing’s down even further. As mentioned earlier, the spacing he ultimately came up with would place 182 saws in a continental 161 saw frame. A stand was converted in 1995 to 182 saws at Elbow Gin in Visalia, California.  The seed tube arrangement was left in place.  Testing was difficult due to limited lint cleaning capacity behind the gin stand.  Certainly more seed was removed from the seed roll and the potential for increased capacity was evident.  Elbow Gin ran this stand for close to 10 years, and it was virtually unnoticed by the rest of the ginning industry.  However, information regarding the saw spacing’s etc. was made available to Consolidated Cotton Gin Company whom Mr.Vandergriff was a Consultant with up until 1999.  From this work at Elbow gin on the 182 saw gin, he began to encourage Consolidated to apply this same spacing to the 198 saw gin.  This would ultimately create a gin stand with 222 saws. This same saw spacing was also applied to their 164 saw stand, that ended up being the Consolidated 184.   Mr. Vandergriff provided drawings and sketches with key dimensions regarding this.  Very little  was heard back from Consolidated on any of this. Mr. Vandergriff passed away in 2004 at the age of 93.  However, at some point in time Consolidated’s interest was renewed with wider gin stands becoming in vogue. In 2009, Loyd Vandergriff was informed that 4 Consolidated 222 saw gins were operating at Lubbock Cotton Grower’s.  He was also informed that “Product of Vandergriff Research,” stickers were on each stand.  Because of this, Loyd approached executives at Consolidated about the 222 saw gin stand, since this was a Vandergriff Idea that had been clearly documented on drawings that dated back to Elbow gin. These drawings that were given to Consolidated were labeled "222 Saw Gin" and had the key specifications for the new saw spacings. Loyd Vandergriff felt that given this, royalties to Vandergriff Inc. should be considered.  Keep in mind that Mr. Vandergriff ‘s  relationship with Consolidated ended in 1999, and he passed away in 2004.  An executive of Consolidated and a good friend of Mr. Vandergriff, was receptive to this and agreed to approach the CEO of Lummus about this issue.  His initial response was informal, but he stated there was there was no justification for any royalties.   In 2013, a Consolidated 222 was on display at the Texas Cotton Ginner’s Show in Lubbock, TX.  A Product of Vandergriff Research Sticker was on the gin stand, and a hand-out giving Mr. Vandergriff credit for his role in their new technology. Once again, Loyd Vandergriff brought the topic up yet again about this issue. This time a formal response was given to Vandergriff Inc. in writing from the CEO of Lummus, stating their was no justification for royalties to be paid.  Vandergriff Inc. had no desire to pursue this any further lacking resources to really take this on.  This clearly, in Loyd's view did not pass "the smell test," ethically or morally.  Since this time, all major manufacturers of cotton ginning equipment are implementing the narrower saw spacing Mr. Vandergriff first used in his conversion at Elbow Gin in 1996. 
Vandergriff Inc wanted to inform the industry of Mr. Vandergriff’s seminal roll in not only wider gin stands, but narrower saw spacings as well. While the industry is certainly better off from his reseach, he received little compensation for his efforts. Today, Vandergriff Inc. had developed a conversion to convert Continental 161's to 181's based on Mr. Vandergriff's research. 
The history of cotton ginning has way of getting facts and events distorted over time. As a keeper of the Vandergriff flame, I am making sure that does not happen here. All information in this article is well documented, and most is included in Mr. Vandergriff's book, "Ginning Cotton, An Entrepreur's Story."

181 "Game Changer" ships. Misc news.

Game Changer Ships & Misc. Updates.

The latest Vandergriff 181 Game Changer Conversion just shipped out to Funston Gin in Funston, Georgia.  This gin is well suited for the conversion with 10' split over head and 24D lint cleaners. The limiting factor for converting more in this plant is press speed.  John Stallings plans to deal with this next year by speeding up his press, so he can convert his other two stands.  Ed Berry converted his 2-161 plant in Alabama last year.  He just reminded me that they finished their season 20 days earlier because of speed up of gin stands. We have enough ribs to convert 3 more stands if you want to take you gin stand and gin plant up a notch.  Remember, our 181 game changer conversion is the only one with the Vandergriff 181 gin rib. The accuracy of  our rib rails is superior, and combined with our precision rib, this arrangement can't be touched by our competitors.  

We have a couple of more sets of 161 Game Changer ribs in stock.

We are just finishing a run of our 170 ribs.  Many are sold, I think we will have 3 sets available.  

We are running more wearplates right now and can fill your orders soon. Get them in.

Game Changer Conversions.

We are starting to get set-up to convert 161 saw gin stands to 181's.  If you are interested in converting your 161 give me a call. The prices for this year are still at the introductory phase and will increase some for next year. This conversion is tested and proven.  Read other blogs on the conversion to get good information as to what is involved, and how it can help you..

We still have a few sets of 170 ribs for a Lummus Gin Stand. Only 1 set of game changer 161's left. If we sell this, another run maybe considered.  We have a couple of sets of 141's.  We are working on a rib for a Consolidated 164/198 and several sets will be running for the 2015 Season.

All Vandergriff Inc. Parts are Made in the USA.  The quality shows. Chinese, Indian or Pakistani parts? You get what you pay for. They are cast ribs, and our competitors choose to cut the manufacturing cost of their ginstand by using these.  You don't have to put up with that. Your gin stand is the heart of your ginning operation and should be outfitted with ribs the will maximize its performance.

Mid South Farm and Gin Show...Report

I just returned from the Mid-South Farm and Gin Show in Memphis this past week. Very pleased with the results of the show and saw lots of friends and customers.

Highlights of the show were as follows:

Continental 161-181 Conversions getting lots of talk and interest. Sold some in Memphis.

Game Changer ribs...people are seeing they are the real deal.

New Consolidated Rib created the most buzz of the show. People want them. Tired of crooked, cheap cast ribs that lose seed and came with a whole host of performance issues.

Here are a few pictures from the show.:

Mr. Donald Van Doorn received the 3rd annual Vandergriff Pioneer Award at the 2015 Awards Banquet. Mr.Van Doorn was an integral part of  Lummus product development for over 60 years. Pictured above is Loyd with Don's 3 children.

Zane Burkett of Burkett Gin dropped by the booth. He has been running Vandergriff 170 ribs for over 10 years. No issues. This works out to be a pretty cheap rib don't ya think?  Don't have to replace them. Just gin. He also runs Vandergriff/American Jet Dryers. He said if someone tried to take em out, they would have to shoot him.

Loyd and Brad Glenn of Sowega Ginning, Climax, GA. Brad has 5 Lummus 170 Gin Stands. 4 Jet Dryers.  70 Bales per hour gin. Have not seen a better operation anywhere.  He runs Vandergriff Ribs and we are going to test a "Game Changer" 170 Rib there for the 2015 season.

We are taking orders for ribs, wearplates, and Conversions. There is a waiting list for some Models.

The Vandergriff 181 Conversion for Continental Gin Stands.

The key to any successful conversion is an accurately drilled and tapped rib rail.  There is no one in the industry that can get this done as accurately as Vandergriff Inc.  My partner, Chris Nachtmann at CNC Performance Engineering for 19 years can hold tolerances from hole to hole at .001.  The machine can drill and tap the entire length of the rail, and we don't have to do it in pieces or segments.  The rail is stout.  Major troubles arise when rib rails are not machined properly on inferior equipment. Hole spacings have been taken directly from Mr. A.L. Vandergriff's drawings he did in 1996, when he converted a Continental Gin stand to 181 saws at the time.

Vandergriff Inc. has a proprietary arrangement on this arrangement used to  install the rib rail.  This fixture holds both end plates accurately and square allowing the rail to be put in perfectly. It all starts here with this type of precision, that will trickle down all the way to the space blocks and saws when its time to put that part of the conversion together. This is not done in a hap-hazard manner.

An accurately machined rib is a must for the narrowest saw spacing's in the industry. Cast Ribs will not be strong enough to hold up under the tremendous pressure that a 200 HP motor will exert. The lack of accuracy in the cast will also allow little variety's of seed slip through the gaps causing a nightmare for grades and loss of seed.  Vandergriff Ribs are accurate and machined from a 1018 domestic steel closed die forging. We don't use inferior material from China!  We have also tweaked the profile to allow for better seed discharge.  This also greatly contributes to increased capacity.

We machine our own end rib filler plates out of stainless steel, with a custom machined taper at the bottom that will accomodate the profile of the end rib.  This will provide a tight seal and eliminate many of the issues associated with sloppy end plate arrangements.
