  Caulk tubes is a great idea... I thought about that a while back... If I ever git to making some bows again I will be doing this...

That's a Killer idea Shredd!  I didn't know they sold empty caulking tubes like that. I'm going for it!

I wonder if they make food grade tubes?  Could you imagine how fast you could make a PBJ with caulking guns?

Thanks,   Kirk

Well i'm going to have to find them locally.... this was the shipping cost schedule for 4 empty tubes.

I didn't know you could buy unused caulking tubes, I am going to have to look for those on this side of the border.

Kirk it looks like Tap Plastics has retail stores in Portland and Tigard. Sorta in your area.

Yup.... But Portland is a big town, and I'm 30 miles south of Portland. Tigard is a 35-40 minute drive one way, and the other one is about the same drive out on the NE side of Portland near Trout Dale. With the price of gas at over $5.00 a gallon i'd be better going with Amazon Free shipping.    Kirk

I like the caulk tube idea, BUT would we be just trading the mixing mess for a tube filling mess?

I think it might be worth it just to keep the epoxy parts free from air exposure & contaminants that you get scooping it out of a can. How often would you have to refill the tube ?  Not that often at all depending on how many bows you are building.

Now measuring it into the cup may or may not be easier depending on how well it flows through the caulking gun. In winter time you would definitely have to keep those tubes hanging in a warm place.

 I'm going to give it a go and see how i like it...    Kirk

  Now I guess that all depends on if you are messy or not...    I think it's a winner...

[Mad Max]

I hear that keeping the air from getting to it prolongs the life of it.
Sounds like a winner to me too.

I just ordered from Amazon

Someone mentioned pump dispensers. You can get inexpensive condiment pumps from restaurant supply stores that will take a variety of wide mouth jars and bottles. Might be easier to fill than a caulking tube and most dispense 1oz per pump.

[Kirkll]

I don't think those kind of pumps are going to work with EA 40. It's just too thick. But It might  work if the stuff was stored at over 70 degrees.

I got a feeling getting the EA 40 loaded into an empty caulking tubes might prove to be interesting. I think i'll try turning up the spray booth temp to 90 degrees and warming the cans up really good. The part B wont be too bad, but the part A is going to be challenging.

I'm afraid to heat it up too much, but if you could get it thin enough to pour like honey, that would make it a lot easier...   I'll let ya know what i come up with...   Kirk

[Mad Max]

Yes I'm setting here thinking how to load part A into the tube also.
If you stab the fill end of the tube in the can to the bottom and wiggle it around a little you should come out with a good start, then add more with a putty knife trying to keep air pockets from getting in.

Yeh, I was wrong.   Not gonna be a mess!

Those are condiment pumps, like for ketchup and mayo. They use the same pumps for Honey.
They will easily pump EA-40.

I used to work in restaurants long ago.....

Those pumps have to get air in there, we are trying to keep air out.

West Systems uses the same pumps??
