Dave The Quick Bag was Invented due myself to being backed into a corner, I found a bunch of body shop film from Germany that a local Kuwaiti guy kept in stock, this material has a side that was treated in a corona or plasma and was coded black masking tape stuck to this side very well, Now the other side was typical polyethylene like green coded, low energy and nothing stucks to it (being the side down in masking use.) You can see it in the bagging pictures. More,

so an easy to use readily avaliable source. I had a similar situation when i first started trying to bag stuff. I had some molds that i was making wet parts out of and i wanted to try bagging some parts. The molds were an odd shaped and difficult to figure out where to pleat (at least for me lol) I had a huge surplus of these big four foot by five foot industrial bags, not sure what they were for but they were on the thick side and polyethelene. Any way the molds fit inside the bag and all i had to do was seal the opening and pop on a port. Worked pretty good and about all it stuck was the consumables so no biggie, tear 'em off and throw 'em out

There is more to this coming up after I eat.

cool

I had the vacuum system worked out where it was self correcting as the work was added, The film was around two mill and had good elongation when I tried to push my finger through it pretty tough (I had no specs).

The first job pilot houses for the patrol boats, I needed like 16 of them now,to do this the plan became ,Gelcoat ,skin out one hour later cure,then 1708 Balsa 1708 and bag co-cure.

Now the method and I had an audience watching btw.

This is where the Kuwaiti's could not believe what they were seeing,The laminate and core were placed,then I came back and put a piece of the film green side (she no sticky sticky)down then, I had a roller made out of 2 wire brushes for a electric drill stuck through a drilled pipe handle and the shafts welded together inside the end of the pipe.

The entire surface was rolled with this tool which perforated the plastic for a peel ply,then my high (dollar) Dinar Burlap breather was placed on with a 2" vacuum channel ,then the bag Black side up again, then 2" 3-M masking tape for a sealer (no tacky tape needed),You can see from the pictures.

This bag became the peel ply for the next cycle. Hence My Quick Bag was Born. I build more than a dozen boats with this system as well. Like I said was in a corner and had to think

Dave, those yellow halogen work lights are great. Workig/repairing the ice boats in winter, we will warm the garage up with a karosene turbo heater while we are working, then place several of those lights close to what we epoxied overnight and turn the heater off. The next day the stuff we glued up is good to go.

Dave Remember these?you can see the size of the pickups

pretty cool, i had seen those pics before and noticed the masking tape. Good think'in on that system and working with what was avaliable. I try to tell people that are in the "do it yourselfer" catagory that you kinda have to be creative sometimes and a lot of this isnt writen in stone. Some times you just have to make a situation work for yourself.

thats a heck of a feed there, hey what kind of hose if that? I have been looking for some bigger stuff but most I've found is pretty stiff. Some of the clear "Home Depot" stuff i am using now has a tendancy to collapse if i add a little heat to the system.
