Hi Arno, good to hear from you my friend, yes it's a good idea to seal the frames and I think I will on this one after I have done all the cross members and deck bearers.
Hi Paul, I use a scroll saw for the frames, once it's hooked up to my old Dyson you get virtually no dust at all, one of my favourite tools and at £90 was worth every penny,, the fillet around the frame is P38. I first tack the frame in place with three spots of a two pack acrylic adhesive, it's not easy to work with as it sets hard in less than two Minuit's but is a very strong bond, then apply the P38 fillet and clean off any waste as it sets.
