Subject: Re: Anybody re-attached a fin? Need advice
Date: 9 Jan 1996
+– I need some advice on putting a fin back on.
Never done it myself. Paraphrasing from an old copy of The Ding Repair Scriptures by George Colendich . . .
Get a grinder. If there is any board de-lamination at all deal with it. Grind the old rope off of the fin. Grind the old cloth off of the fin. Or get a new one. Prep the slot. Allow for fin glass. If there is _ANY_ board de-lamination at all deal with it.
| How much angle should the outside fins have from vertical?
Use cardboard to take the angle of the fin that remains and use that on the other side. Be patient as you tape it into place. If you can’t do that then maybe the original shaper has the angle spec for that board.
| What is the general order between cloth/rope – is there a layer of | cloth first then the rope then some more cloth?
Rope under cloth. Cloth over entire fin. Twice.
Cut some cloth that will cover the fin and overlap onto the existing board glass, flap-like. The flap is your stress defense. 6 oz.
Glass around the fin slot, unless you don’t need to qcel the board and the fin glass will overlap the board glass as is. It is said that the ripped fin slot that doesn’t need prepping is a rare thing.
Coat the fin with resin. If you did glass around the slot it should still be wet when you do the fin glassing.
_Saturate_ the rope and lay it along the fin, avoiding bubbles. Add the fin cloth. Press the rope into the base of the fin. Do the other side. Then brush on some more resin. Then lay down the second layer of fin glass.
Squeegee, taking care not to separate the glass from the rope. Hot coat. Trim.
Grind and sand, after a long wait. Rope that isn’t completely set and dry will cause much grief.
| How far does the cloth need to go up the fin?
+—- All the way. Twice.
Accurate details can be had from Village Green Publications 6362 Glenhaven Road Soquel CA 95073. The Ding Repair Scriptures $8.95 + $1.50 shipping. CA residents add sales tax. Overseas add $1.50 more for more shipping. All prices subject to inflation.
I’m not connected to the author or company, just a fan of the book(let). Great step by step how to, cool cartoons, lots of ‘what to avoid’s. A classic.
