2775Hrs – Nine Hour Sanding Marathon
I hadn’t anticipated such a hard day’s work today but I now have lots of glass fibre itching to go with the sore arm and shoulder!
Of all the tasks necessary to build a Tiki 38 sanding is the most unpleasant, no doubt about it.
It took me 9 hours of it to get all four beams ready for the next stage of work and I’ve now decided what I’m going to do.
The tops and bottoms are glassed and I now intend to glass the sides in the areas shown in red below. I’m not going to attempt to glass the recesses shown in orange, they will just be painted.
I’d pretty much decided that even before the comments left by Cynthia and Jean-Paul. It’s interesting to hear that they have to repair areas even after fully glassing the beams on ‘Apatiki’. I want to make sure that the main timber joints are reinforced hence the decision to glass the sides but I figured that trying to glass into the recesses would be time consuming, difficult, would not add any strength and worst of all create possible hidden areas where rot could take hold over the long term.
I’d far rather be able to see if problems are developing and repair as necessary than get a nasty surprise someday.
Roger’s question about glassing over edges and in/around corners is indeed timely. I’ve found that it’s nigh on impossible to glass into sharp corners, it’s essential to create a decent size radius by routing external angles and epoxy filleting internal angles. PeelPly is a great help as well because you can pull it tight over the radius to help keep the glass in place whilst the epoxy cures.
It’s inevitable that there will be a few places where air bubbles are created so some sanding back and filling afterwards is inevitable.
