Fairing Thickness ?

[ccx2]

Hey , Glued the bottom panels on my Garvey and had a screw up, nuthin major but one panel i couldnt draw down like i wanted it along the keel and im going to need to fair this spot out about 1/16 to 3/32, i am planing on fairing , sheathing,then tapeing, then finish fairing, sound right? will the fairing stand that thickness?

Is this a wooden boat or a fibreglass boat? If it's a fibreglass boat, it doesn't much matter how thick the plastic is.

I don't see a problem with that much fairing. Use thickened epoxy and it will be stronger and tougher than the wood.

Ideally you don't want fairing material between your fiberglass and your wood panels as there is very little strength in that layup. If at all possible, do the laminating first, then filler should be layered on top. Im just not sure if you mean that the edges of the ply aren't lining up appropriately, so a photo would be beneficial.

If your bottom planking is 9mm (3/8-inch) it might be easier to just plane down the high spot. You've got that nice DF keel backing up the ply panel, so there's plenty of strength there to stand a little lost panel thickness. Pics, we all love those pics.

Bob, its a Plywood boat.

Todd, after some thought i think that would prob be the best solution.

Spookaloo, would you think thickend epoxy as suggested would be strong.

TerryLL, Yeah i thought about that, maybe plane some and fair some. Daggit, i dry fit it so nicely and was really proud of myself then when i when i glued i set the panel on and lined it all up then fitted and fastened the chine and when i went to squish it down along the keel i had one area about a foot long that didnt want to go down all the way so i walked along it to use my body weight to mash it down and squeeze the epoxy out and that helped some, i think i may have had to much epoxy in that spot and along the whole keel in general because i was afraid t would starve the joint and i also had it thickened pretty thick. Oh well ,at least its on the bottom where it wont be seen when its right side up, BUT i know its there chewin a t my pride:)

You probably know this by now, but when fastening down the bottom panels it's best to do the keel edge first, especially if the panel fits into a rabbet or butts the other panel. Then, if the panel turns out to be a little fat, a few swipes with the hand plane can correct the problem before the rest of the panel gets locked down. Another option is to plan on a small gap on the centerline to be filled later, simplifying the keel fit.

Yep, one of the panels didnt get down flush with the other for a foot or so about three foot from the stern, dont know why because i lifted it and couldnt see a cause or anything in the joint, i tried good licks with a rubber mallet and then standing on it but no luck. Wish i had peeled it off and scraped all the epoxy off and started over today. Do you think if i wetted the area out and then lay a layer of thickened epoxy over it stuck off of the high area let it dry, sand it, then sheathing, tape joints, fair, that would work.?

Given the choice I would shape it so that its rounded enough for glass to lay on it, then lay glass. After it is well adhered, I would build up filler to the levels necessary, and fair back the shape you want to show. This way your glass is doing its job against the wood and the filler is just there to fair.
