blocking off option

I was thinkin the same thing.. also how many times has he tracked right thru the paint

Thats me running the gun. We did 150 of these things and only hit my shoe once. It took me and a helper about 20 minutes to paint. JIm

That thing works great Jim, they look good and no more stenciling nightmare. Congrats!

Jim, Could you post close up pictures that show the details of how you put that together. I'm not sure, but it looks like you rigged up a cable from the trigger of one gun (top) to the other (bottom). That thing works great! I want one!

Thats all the pictures for now, until I decide what I am going to do. Jim

Do I sense a patent in the future? Don't blame you at all.

I replaced the huge 3/8" 50' hose on one of my line lazers with a 1/4" 50' hose a while back and there is no hour glassing in the lines and I shoot latex almost exclusively. The new hose is an off brand and now has a cut on the outside. I assume that a bursting hose is a little more excitement than I care for so I plan on replacing with a 1/4" Graco hose because they appear more durable. The question is, does a 25' hose have enough reservoir volume to control the pump surge or do I need to stay with a 50'. Has anyone experimented with this? I would appreciate some feedback if you have any. Thanks

I suggest running two hoses all the time. Leaving two hoses on keeps you from having to undo the striping gun to do stencils and detail work. It also adds capacity and you can cut down on hose length. Also.... stripe with the sort hose. Use the long hose for... well, you get the idea. Another tidbit..... put a painters whip on the end of each hose just before the gun.....adds a little more pulsation compensation and makes life a lot easier in handling the guns. Graco is playing a bad joke by putting that monstrosity of a hose on striping machines.

That is my M.O. 2 hoses but will the 1/4" 25 foot hose enough to compensate for the pump surge. 50' of hose is a pain if I don't need it. Have you ever used 25 foot hose?

Calif Striper, Graco made the decision to add the 3/8" hose to cover "worse case" scenarios. This includes: paint issues, temperatures (paint and air), geographic location, various brands and types of paint, and pump condition, etc. To put things in perspective, a 1/4" by 50' hose holds .2 gallons. It take just a few seconds to wash it out. With that you should be fine. Going to only 25' you are getting closer to the "edge". Why bother? Knowing the above and more, I would be running a 1/4" X 50' hose, recognizing that as it gets colder and storing paint outside, to just keep an eye out for potential line quality flaws. I might never see them.

I was thinking of having some custom hoses made for me through a "hose and coupling" company. The reason I even thought about having the hoses custom made was the exuberant prices Graco wanted for the 2 short high pressure hoses coming out of the pressure regulator control of an old Graco 3500 I had just bought and was repairing ('was in very clean shape and bought it for nothing). I thought about making several 75' long X 1/4" o.d. hoses to use on my machines, allowing me to have 1/2 of the hose tightly wrapped around my machine and well secured, yet ready for me to uncoil the extra hose when it serves me have a longer hose. Adding a whip hose would also benefit hand work, though If I could find a very soft hose which was still very durable, the benefit of a whip hose would be less needed. In the past I have used some very soft hoses which were almost enjoyable to use and recoil, like the a pre-titan speed-flow hose from a Powerliner I bought new years ago. It's paint hose bends like 'butter', unlike Graco hoses which are very stiff for doing hand work and are a 'Dog' to recoil,.. but I'm sure they are trying meeting a "durability goal" and not a "user friendly goal" Anyway, anyone know what specs constitutes a good paint hose that would be very soft yet durable and safe. I know Cormac said the fittings should be" E nickel plated not zinc"?

Markings #1, I believe we still use " hose with SST ferrules (wetted parts). There is a lot more to hose than soft or stiff. We meet safety factors (4 times rated PSI) which does not do much to help having a pliable hose, but it keeps you safe. Our airless hose also has a conductive core that also keeps you safe from static discharge or in short, FIRES. Hydraulic hose is not a satisfactory replacement.

Ya, I know you can't use hydraulic hoses, but I was wondering about the different webbed core materials like stainless or other conductive materials, plus the different jacket or casing material options? If someone has only used Graco hoses in the past they might be surprised how much softer and 'easier to use' some other paint hoses can be, especially if you are using 3/8" Graco hose (nothing against Graco, I think I know were they are coming from... well, except for that ridiculous Fat Max hose when trying to stencil several hundred numbers!).

Suddenly I am having a problem with my LL5900. I have always left latex paint (Pervo) in the machine under pressure. It has always stored well and ready to shoot no matter how long it has set. Now the paint has been setting up in one or other of the hoses within a couple of days. Cleaning it out isn't fun. The 3900 using the same brand of paint, only blue, is fine. So I don't think that there was a formula change. Anyone have any ideas?

maybe seals are getting worn and you are letting out a little pressure and are experiencing an air pocket

I rebuilt the pump about a year ago and when I start it up the pump usually takes one stroke, so it's not loosing much pressure. But that was my first thought, I was wondering if I was missing something else.

cali, check all of your hoses and hose clamps to make sure they are tight. Make sure your bottom filter is completly sumerged in paint, water, or something. also, i have always found that if i turn my tip sideways when finishing it does better. Im guessing just that little air that can come through the tip had always helped stop it up while setting. good luck

I just clean it every time. I know...time consuming, but I have NO problems that way.

our line lazers came with whips on them the whips are 1/4 inch the hose is 3/8 we just let the pressure off the gun and the hose rolls up fine we use the velcro to hold most of the hose to the machine i think it works great

When was that last time you did several hundred stencil at one time using the 3/8" hose? Also, you should get back to me after uncoiling and re-coiling the 3/8" hose several hundred times -- good tools should be a pleasure to use unless there needs to be a compromise on efficiency or Safety, neither of which I believe the applies to that ungainly, clunky, burdensome, ill mannered, overkill of a hose .
