Re: Help with Oil-canning

I disagree with above. To stiffen a layup you need to add to the INSIDE. It can be just a diamond shaped piece that covers the flattest part of the hull. I am curious about the strip thickness you used. It seems to me your fours layer of 3.25oz should have made a hull stiff enough to not oilcan, at ...

Re: Ash bottoms for tough river?

I have to agree with all of the above and add this. Kevlar inside, glass outside. If you are adding layers to the bottom, inside or out, make sure you stagger the edges of the layers by several inches. Laminates often fail at an abrupt transition in stiffness. Spreading out that transition is always...

Re: Advice needed - Fiberglass/Epoxy shaping and filling(?)

Patrick! A tough situation to deal with at a time when more progress toward finishing would be desired. Your patience with solving the problem is good! I agree that you need to finish the flattening process. You are close. It does look like you have breached the glass already and those spots will ge...

one more thought on this

Early on in my boat building experience I re-used mixing containers as I was glassing. The mixed resin that was left coating the sides and bottom of the container seemed to mix in fine with the new resin. The problems began appearing as I squeegeed the excess resin out of the cloth. Patches of resin...

maybe contaminated cloth?

The pattern looks like the weave of the cloth. It is possible the cloth is contaminated. Handling glass cloth can transfer oils from skin or sweat. It can also come from the supplier with contaminates in the finish or inconsistently finished cloth. I am always cautious about cheaply priced cloth. So...

Re: Refinishing and blotchiness

What it looks like when it is wet with water is pretty much what it will look like when the new finish is applied.

If you have abrasion down to bare wood make sure you let that wood dry thoroughly before you seal it back up.

Re: Ribs at the seat

I have had a 300 pound partner in a bow seat without any problems. The seat frame bowed a bit, but what concerned me most was the inwale from which it hangs. My gunwales were screwed on from the outside. That leaves the inwale a little stronger not having all the screw holes through it, just the tip...

Re: Ribs at the seat

Are you hanging the seat from the gunnel or attaching it to the hull?

Re: Replaced knees

If 12 feet is your #1 criteria than the solo passage should not even be on the list. It would not be easy to shrinking by spacing mold closer with the tumblehome. Also, if you shrink it you would want to make it deeper and that is not going to work with the tumblehome. The solo passage is a great ca...

Re: Replaced knees

http://www.newfound.com/Otter.htm Here is a canoe you may be interested in. Its symmetrical so you could stretch it out a bit if you wish. What I like about it for your situation is that the sides are straight up, no tumblehome. That would allow you to make it a little deeper, which I would suggest....

Re: Replaced knees

I am assuming you are looking to sit, not kneel. My partner has two new knees and she finds kneeling quite uncomfortable. Are you looking for a tandem or solo? If tandem will you be in the stern or bow? Beside not kneeling, another issue with knees is getting up from low sitting positions. Consideri...

get a English measuring ruler

I really think it would be easier to just get a English rule for the project. Its not less accurate, just different. As for finding canoe plans in metric, there may be some, but you won't have many to choose from. Consider that the type of canoes you are interested in building pretty much developed ...

Re: Non-Bear Mountain Designs

I would have to dig the molds out of storage to measure the seat height off the bottom. I no longer have access to the canoe. As you can see from the photo the seat is just a few inches below the gunnel. The hull was 14 inches if I recall correctly, but with that v-bottom the depth number is deceivi...

Rushton v-bottom designs

Interesting to see this hull being built. I built a similar hull from the plans in the book about Rushton, the Canadian Ugo or Vayu model. 15'x30". I built it as a solo tripping canoe and like it a lot. It has the same "deadrise" v-bottom as the Arkansas Traveler. You will find the in...

consider 4 ounce double and a caution

I think that 6 ounce double layer inside and out is overkill unless you are really going bash this canoe around a lot. I went from 6 ounce inside and out to 4 ounce overlapped below the waterline inside and out. This has proved to be a durable lay-up for canoes that get used hard in rough places. Yo...
