So it has been a while since I tested the Corve and the skin finish is not as good as epoxy, kept at room temp or above, but acceptable. The problem I personally have is the styrene odor. I have worked with only epoxy for 15 years so I have become spoiled. I may go back to epoxy.

I ran a test using CORVE8101-50 VinylEster Infusion resin. Skin finish, looks very good, like epoxy and at room temperature. So I bought 5 gallons, I will let you know how it goes at scale. I will do a low temp post cure.

Agreed.

No in theory it sounds great, do not clamp tight, but we have all done this and stuff moves around and we are to leave our c clamps loose? It does not work, maybe spring clamps in their limited applications. I am attaching wood gunnels inside only to infused canoes in the mold. Once cured...

I have been using Duratec Surface Primer for fast build up, maybe 30 mils at a time on plugs before sanding and polishing and forgot it was rated for 10 mils or maybe less. Pocock the rowing shell guy, I will revisit him. I looked up Guard Dog UV9 and got the impression small quantities may...

The Sunshield looks like UV stabilized clear gel coat. I am trying to stay away from the labor and the weight on these canoes. 15 mils of gel coat is a few pounds I need to avoid, I have been staying under 20 pounds with cherry trim and gunnels. I could shave a little weight with aluminum...

Thank you, I will look at Sunshield seriously. It opens a lot possibilities in resins. The question I still ask is do we trust supposedly UV stable resins. I may not have to make the next step to a spray in (which is tempting ) I have been considering Adtech 820 it is locally available for...

fallguy Gurit indeed does have several infusion resins. One system may even cure with UV. I do not think any are recommended for long term sunlight exposure. Their Tg/ HDT look to be around 67C or 152F with a post cure. Those temps are right where I am having problems with carbon canoes...

I am building a few sub 20 pound 11.5 foot solo canoes. Kayak paddle, sit on the bottom or kneel and freestyle with a canoe paddle. I am using a Resin Research epoxy infusion resin currently mainly because i am doing skin coats with no gelcoat to save weight and RR has UV protection built in...

Milwakee makes an angle drive that seems robust. It is an option to attach to some of their drills I recall. I bought one years ago for about $60.00 and they claimed they would rebuild it for about $30.00. It has a 2/3 ratio or a 3/2 ratio (reversable). I tried it on my bow facing rowing...

Good discussion Sorry I got to it late. Steve, I also own the Amprobe ULD-300 and I believe you are correct it does not perform. There is a discussion on the Composites Central forum a while back discussing leak detectors and no one had tried the Amprobe but reliable members did like other...

Jeremy, It would be great to hear how you feel about your project, what works and what you might change. Jim

Kevlar is light and does float so will be too resin rich by itself without bagging or infusing. I think one could hand lay up the outer hull making sure it is well sealed, a layer of kevlar then glass cloth would be fine, then flip it and bag or infuse kevlar and perhaps glass on the inside...

If wood is the chosen hull material I think S-glass outside and kevlar inside makes best use of material qualities. The bow should have a heavier lamination schedule and a lot of rake to ride up on sea level ice rather than push through it. Following whales and avoiding ice: we should all be...
