Re: 1965 Johnson Tri-Hull restore!

Your Glassin is lookin good. I would recommend waxin the last coat. Some don't but I do. I told you that 5 gals might be what you needed to finish.

Thanks! I got the wax, I thought it would add extra time, since to paint it, I then have to sand it again to get the wax off. For sanding the final coat, would a palm sander do? Belt Sander?

I'll likely pick up another 5gal of resin, but I don't think I'll use that much.

Palm Sander will be fine.

Ok. I'm guessing you don't have to go far to get the wax off. On the bottle of wax it says to wipe with acetone, then sand, then wipe with acetone again.

Got one more piece of CSM in on the deck, then ran out of resin, got to pick up another 5gal of resin tomorrow. One more piece to go in the middle of the deck, and the first layer is done. Should be able to do all of the final layer on Monday!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Then put it all back together!!!!!!!! Hopefully finish June sometime.

Thanks. Just picked up another 5gal of resin, and 8 yards of CSM. I'll put the final piece of the first layer in on Sunday, and should be doing the full layup on the final layer on Monday!!

Just out of curiousity, and for the benefit of others, why don't you describe your methods for laying your CSM and pouring your resin over a large area such as a deck. How much resin do you mix at one time. How do you spread it around? What about the edges and the corners? You're the PRO now, Share the KNOWLEDGE!!!

Hey, sure. I mix 32oz at a time, I made my own mixer for the drill, just a piece of 1/4 steel rod, I cut a small piece about 3" long and welded it on the end to make a T, works great to mix resin and PB, the first batch of PB I made I mixed it by hand, and was really tiring, I thought there has to be a better way to do this, so I just made that simple mixer. I then pour the resin all over the CSM in a couple feet section at a time and use a body filler spreader to drag the resin around the cloth until it soaks it all up then roll it out using a fiberglass roller until the air is all out.

For corners I usually make a few relief cuts in the CSM, otherwise it likes to bunch up and takes a bit more work to get it to lay down. For say in inside square corner I do the same one cut in the middle on the top and bottom, the top will wrap over the top edge in either direction.

CSM is really easy to work with on the flat section like that, I found with 1708 you really need to work it well with a brush to get it to soak up resin and conform to any bends, but it lays down real nice. For vertical sections I find I just use a cheap paint brush to wet out the cloth, I'm sure a small paint roller would work better, I've just not bought one.

I think that's everything. Pretty simple really.

Got the last piece in this evening for the first layer, and got the pieces cut for the second layer of CSM! Tomorrow is the big layup of the second layer!!!!!!!!!!

Re: 1965 Johnson Tri-Hull restore!

Got the final layer done today. It seems to set faster with the wax!! I'm a little worried about the last seam, before I could get to it, it was already curing to almost dry to the touch, hopefully layer over that was ok, there was nothing I could do, already had half the last piece wetted out. We'll see tomorrow. All in all, it seemed to come out ok though, my first time doing this sorta thing, next time I'll be a pro! Well according to the wife there wont be a next time! LOL, well maybe when the kids are a bit older and I have more time. Now just have to sand it out, and paint it, make a transom cap, and mount the motor back on, and a little electrical work and mount the Gas tank.

Re: 1965 Johnson Tri-Hull restore!

PW,

I been thinkin. Now that can be dangerous sometimes but here goes.

Grind and sand the top of your transom until you get it the way you want it. Then wax it down really well with 3 or 4 coats of Johnsons Paste Wax.
Next cut 4 pieces of 6 " wide by 5' long of 1.5oz CSM and saturate em with resin and then mold em over the top of the transom. Use your gloved hands to mold it nice and tight to all the cracks and crevices. When it sets up it will pop right off because of the wax. You can then apply more layers is necessary or call it good. Paint or gelcoat it and you've got yourself a transom cap. Like I said, it can be dangerous at times.

Re: 1965 Johnson Tri-Hull restore!

Man, you're moving right along. Nice work. I gotta question for you. I think when you started the topside of your deck, you had about 2 - 2 1/2 gallons of resin, and you bought another 5 gals. How much did you end up using of the extra 5 gals? I have to order mine from out of state and the shipping and hazmat fees are pretty steep.

Hey, wood, that would work. But I'm going to make a custom aluminum one!

I used a hell of allot more then I thought I would. I think I used better then half of the new 5gal container! From all the restores I've read it seems most people use about 15gal of resin, so I figure I'm doing good! And the last container wasn't quite 2.5gal left, more like 2.

Re: 1965 Johnson Tri-Hull restore!

What would be the best way to drill oversize holes in the Transom? I got some big Forstner bits that might work ok? My biggest drill bit only goes to 1/2"

Re: 1965 Johnson Tri-Hull restore!

These will work.
What are you going to be installing. I use the double rule. i.e. If the shank of my screw/bolt is 1/4' then I drill a 1/2" hole.
Hint: Drill a 1/8" hole all the way through first. Then drill the finish size 1/2 way through from the back side and then finish from the outside. This alleviates chip out.

Ok, I have those bits, but thought they wouldn't do a clean enough job, but I'm sure they'll be fine. I'm mounting my outboard, I think the bolts are 1/2" bolts. So drill to 1" then fill with PB then redrill?

You got it!!! You KNOW you can sharpen them with a flat file!!!!
