Chop Gun Systems

Hey everyone,

Does anyone have any chop gun systems that they would recommend and what size of compressor you would use with it? Also a typical cost of one of these systems?

 

Chopperguns !What are you reallylooking for ? what are you going to use it for ? Theres a range of guns availible under differant brand names . Compresser required anything bigger than 25 cu ft per minute and run a 1/2 air line to the gun from the wall !! the bigger the line the less problems you will have when running any kind of air equipment also water trap make sure you use a reaiiy good water trap .You need dri air !!!!. If the climate is cold where you are ice build ups in the line and where the air exits the pump and the chopper motor can be a major problem!! Dry air solves part of this
I always set up a 1/2 airline to the gun and then use a tee fitting on the machine to runn other smaller things such as grinders and spray guns etc etc saves having to have airlines running all over the factory !1/2 lines means also 1/2 fittings all round dont fit a smaller coupler any where in that line !! restriction causes hi speed air and temp drop and ice build up Always us a compressor thas much bigger than you think you need . Big pipes and lines also act as aqumulators and give capacity to the system .
Do you have a air system in the factory already ?? theres installation methods you need if you are piping your factory

Ok chopper gun have you ever used one ? :?:

 

Im looking at building drift boats first as a hobby then progressing into a side business. I want something that can handle spraying up to 20-50 boats a year. Do you have any recommendations? I have no experience at all with fiberglass but looking at getting into it obviously.

 

Ok
i wish i was next door but im not !. glassing is an interesting field to be in ,i started 1972 and still enjoy the challenge everyday and the thing of seeing a new finished boat getting launched , its like watching a baby being born .
Just get a good grounding and learn the basics of what works and what dosent ! what you can do and what you shouldnt do . then move on from there , when things turn to crap and they will at some point theres always a reason so you need to be able to back peddle and understand what you did wrong and move on from there . I could write a whole book and give to you but you have to do the ground work first . Study and understand all the materials you will have to work with !!.keep them to the nessesities of what you will need every day cleaners wax's glass , resins , and gelcoats etc etc
Personally i would forget the chopper gun for a while and concentrate on doing hand lay up till you get to recegnise what the differant weights of glass look like while you are using them so later when you do start spraying you can instantly tell if you have a even layer all over your mould . A chopper operater has to be an artist , he is in total control of what is Happenng , he can make of break a product so its really good or really bad !! . I have a guy working with me and even after 6 months still cant get it right simply because its just a job and has little to no interest in what hes doing !! .
There some basic things that should become instinct such as weather ,temprature and humidity !, these are things few people take to much notice of but affect what you do every hour of ever day . it determins the catalyst ratio you should be using and govens the gel time and the cure time of whats happening and is changing every hour of the day like it or not !!
Later during the winter cold will make you realise the advantages of a climate controled enviroment 24 hours of the day 7 days a week so everything is predictable always , its 24 hours so moulds and equipment and all materials are at a constant temprature and problems never seem to happen because of it . A really big wall dial in a easy to see place is a god send as at a glance can see where its at !. I am sure others will want to add the bit as well !!

 

Are you still looking for a chopper system?

 

I'm looking at a chopper system myself. There are only two types available where I am, the Graco and the MVP. Which one do you think is better? Price wise, Graco is 90% more expensive than the MVP.

Did you get any reply's ?
If you looking at making boats a gun can be a good investment but just use it as a wet out unit to start off with !! they all spray catalysed resin and all do the same thing , they all have adjustable catalyst pump setting for Different ratios just some are easer to adjust than others .
I have used and spend may hours with external mix guns and they would never be my choice ! give me internal mix gun every time!!.
Chopper guns are made to be used and are capable if applying small amounts of materials like glass and resin or large amounts in a very short time . its completely up you the operator as to how good the job turns out and how good and consistent it is !!, he has Absolut complete control of his environment and what is happening .
Like any and all equipment used in any glass shop its gets abused and covered with fine spray so in a very short time that brand new shine equipment looks like its a 100 years old .
Clean guns well looked after hardly never break down or have any problems !!,cover it up with clear plastic or spend countless number of hours cleaning it all the time !! .

Something very few people ever ask or take any notice of is the weighing of glass and the resin that the gun is using . This is really ,really important if you want consistency and uniformity then measure you area you spraying accurately and know you lay up and how thick you want and work out how much glass needs to be used !! you can also work out how much resin is required to do that particular job and then you will also have the glass to resin ratio !!!
There is no reason why you cant be as accurate as doing hand lay ups or even better ! no reason at all !!
When the item is removed from the mould you have a final weight ! all this information is related and when you become really proficient you will be able to spray the job and not have to look at the scales and every item comes out +or- only a small amount ,for a good operator this could take about 6 months to master continuously all the time

 

Brokensheer and Laurenphoenix, thanks for the reply. I'm afraid I forgot to mention that we're based here in the Philippines, and that I only have the two mentioned (Graco and MVP) above to consider. I would love to have the option in the choice of equipment that you guys have over there. But alas, a man must make the most of the situation.

 

Yes, I realized you were based in the Philippines and that's not a problem, we ship worldwide. While a lot of our business is in the States, most of our equipment is overseas and we have distributors. We have sold equipment to the Philippines, been a few years, but I would love to get more business there! If you like, you could contact me directly: (727) 393-1818, laurenphoenix123@aol.com. I also have skype which I use regularly: hummingbird375. Let me know, would love to help
