Yet Another Transom Job in the Works - ?ions

[ob1jeeper]

FJ,
Did you get all the wood out yet? I had to sharpen the electric chain saw a couple times, because the resin in the plywood, and scraping along on the fiberglass had a tendency to dull it over time, but it did the trick for me for ALL the wood removal. Clear to the bottom, and with a little side pressure, it cleaned off nearly ALL traces of wood from the transom skins also.

Sounds like you're keeping the project rolling along nicely... Enjoy reading your posts

HIN- get some tin and some stamping letters/numbers and then imprint your HIN into the tin. Flip the now imprinted tin upsidedown and lay some gel-coat/or resin then some mat 2- 3 layers. You will now have a section you can laminate into your transom and it will look factory.

ob1jeeper - she is just about cleaned out now.... Thanks..

The plywood in my hull had a bunch of staples in it that gave all my tools a hard time..

I have not seen anyone mention the staples in the original wood??? But when you hit them you know it....

FJ,
I had forgotten about the staples While most of the ones I hit were rather rusted, there were quite a few which were solid as well. They obviously don't help with keeping acceptable blade sharpness either

Tom-

I can not take credit for coming up with the technique, I learned it from Mike @ Wildfire

The old transom wood is 100% out.. Finally!
Down to bare clean fiberglass all the way around the edges.

Another quick question - I plan on extending my stringers up the back of the hull a bit and glassing them in - What type of wood should I use as a core for this? Should I laminate two pieces of 1/2" or 3/4" ply?

Also - is there any certain type of plastic sheeting - other than peal ply - that will work to keep clamping devices from sticking to the curing epoxy? I remember someone talking about this on another post and cannot seem to find the info.
Thanks

FishJack -

I never mentioned it in my rebuild, but I ran across small brads in the transom plywood, guess they were there to hold the two sheets together thru the build process.

As to your questions, above, I made up my knee out of plywood, used both 5/8 and 1/2 to get what I wanted, 3 pieces in total. After cutting them to shape, I epoxied them together, leaving the outside dry, and clamped them up to cure. Later, when installing, I used wax paper as a release paper, with another piec of 1 by pine, or a piece of 1/2 ply as an external clamper. I had put one layer of glass on the pre-built knee, before installing, and then several more layers of glass over the knee and onto the transom / hull, after installing - there's some pix in my rebuild, way back on about page 10 or so now.

hope that helps some

Thanks Bill - This brings up another question -

I might be running low on marine ply by the time I get ready to fab some misc. deck braces and knees - Is there any other type of ply that is accepable that I can pick-up at Lowe's or HomeDepot?

OR is marine ply what I should stick with for the entire project (knees and other deck support pieces)??

Regular 2,3 or 4mill visqueen will come off no problem after it has set up. Don't try and pull it while it's still green. The same goes for peel ply.
