Re: 69 Ouachita restore

Not a pro but have dug into a few of these in the past. Where you added the half round I always understood to be a channel to aid in drainage to the plug and was left empty. If yours was filled I don't understand why. Good work so far, really enjoy this stuff.

Need more details. Please explain, Step by Step exactly how you installed this, materials used, and mix ratio's used. Temps at the time of install.. ALL the details please.

Bedded in PL but it had been drying for a week. 1/2 qt resin, 1/2 qt cabosil, 1/8 cup chopped mill fibers, 5ml hardener. temp about 73

I think ezmobee got it right, only that i had some globs of PL here and there so i ground those down and while i was at it I just kept grinding to smooth it all out. I think grinding the dried skin down allowed more gassing, at least that's what i'm hoping. Just glad I only did one side of one stringer. Figured I would start small so i don't have any major problems.

Re: 69 Ouachita restore

Did you wipe it all down with acetone first? did you precoat your stringers with resin first?

Wiped down with acetone. Precoated with resin and styrene.

Styrene????

Re: 69 Ouachita restore

Yes, to thin the resin to coat the stringer. I did this a couple of weeks before hand. I understood to help the resin soak into the wood better. Was that a no-no?

You would normally thin with acetone. Styrene will work but its a nasty case of bad stuff.

Re: 69 Ouachita restore

IMHO you don't need to ever thin the resin. I used to think so, but after being educated here on the forum and other research I've been led to believe it serves no good purpose. Others may have different opinions. The main thing is... you pre-coated the wood. The issues shown in your pics, to me, indicate some sort of contamination. Either from the PL glue or something else that caused the Thickened Resin (PB) not to adhere properly. You will need to grind it all off and try again and try to ensure that the surface is totally clean and free of any contamination. That's how I would do it. I would recommend you use the Metric system when mixing your resin. It's soooo much easier to ensure you get the proper ratio of 1.0 to 1.5% MEKP to Resin volume. You can in some circumstances go to .75% but I would not go much lower if you want a good strong cured mix. Again, my opinion and others may differ.
