Default Stringer Install , Vacuum Bag and Infusion?

I have a old Jet boat that needs the Stringers and Transom replaced , I have to Laminate 3/4 ply to make the Stringers . I'm using B70 to Bed the Stringers in the hull.
I'm thinking I would like to Vacuum Infuse the 1708 tabing and reinforcement to the hull , one shot .
Anyone have experience with this ? I wonder if its worth the trouble ? I think it would be a Whole lot less mess or PITA than wet lay up.

for something that minor its not worth the trouble. Not knowing what the surrounding structure is like getting a good seal and pressure would be difficult. Now if its purely for the experience then its a good place to learn some new tricks, its certainly a worthwhile process and worth knowing. The efficiency of materials and lack of mess are worth it thats for sure.

Hey Dave ! The Sealing issue is what I was worried about . But I have a 5 HP Vacuum pump I got from an auction at Penske's race shop . It was used for making Indycar tubs .
I think I can overcome the Leaks! At least I hope so! I'm going to do a test pull without reinforcement , and see if I can seal it down . I'll post picks .

nice! I have a two stage Edwards M30. Volume is what you need as vac is linear once its up to (or down to) 29.92 in/mg but it sounds like you have the right pump I'm sure anything Peske had is top notch. My pump was almost $3K and sucks! lol

Yes do a test pull to see if you can even get a seal on the area. Its not so much overcoming leaks its more about a total seal. If you have a high volume pump and it can overcome the leaks it will most likely pull more air into the laminate. I have a regulator i built (thanks Steve Koss) that allows me to adjust the draw in case i want to lighten the bag pressure. Some resins can actually be pulled almost dry if your not careful.
