455Hrs – Unexpected Work
Due to a failure of the laser equipment (a tad worrying) my treatment was cancelled for today and re-scheduled for tomorrow. This hasn’t helped my nervousness any so I was glad for a few hours boatbuilding to take my mind off it. Not that doing 24metres (80ft) of fillets is particularly interesting! Anyway that completes all the underside stringer fillets in the starboard hull so I’m pleased with that.
I have also been thinking a lot about the sheathing. Although I was relatively happy with the ‘dry’ method test I did, comments from Thomas and discussions with my epoxy supplier convinced me that there was still room for improvement. I think I have a plan. I am going to give the hulls a coat of epoxy, let it cure and then give it a light sand and washdown. I will then apply the twill dry, wet it out and then use Peelply over it. Everything I have heard and read indicates that this will give a far better finish and I will not need to sand before applying the filler coat. I have already used a 50mm wide Peelply tape to good effect on the bow and skeg sections. So I have ordered a 100m x 1.5m roll of Peelply today. For those that don’t know Peelply is basically a finely woven nylon cloth that is placed into the wet layup and then squeeged out. It doesn’t stick to the cured epoxy and when removed it pulls off the amine blush and leaves a slightly textured surface ready to bond to. It’s not cheap but having convinced myself that it will help me produce stronger, better finished hulls I had no choice but to go with it! So all being well I’ll be sheathing hulls next week, at least I will if I can see them!
