After Deck / Hatch - If at first you don't succeed ...
give up and go home! Oh! I am home ๐
Since I need access to the rudder the after deck has to be made as a removable hatch. Would you believe at the last refit (25 years ago) I actually managed to shoehorn the RX and RX NiMH battery in there as well!? Pic 1 shows what it looked like when I started this refit, after 20 odd years in the cellar ๐ฒ
Anyway, I wanted the deck to be mahogany to match the cabin roof and as a hatch it was obvious that it would need a subframe. Pic 2 to 5, had to open a new bag of chomp chomp clamps ๐ Trial fit Pic 6. SFSG!
Under side was sealed with two coats of EzeKote and fixings added;
neodymium magnet
s at the forward edge, domed captive nyloc nuts glued into the under frame at the aft edge. Pics 7 & 8. These will then accept 4mm studs screwed into Riva style fuel filler caps to hold it down and (hopefully) keep it watertight.
Mahog was then finished in the same laborious and patience testing process described above (or is it below๐ฒ) for the cabin roof and decks. Pic 9 shows it screwed down with normal 4mm 'Camembert' head screws - Why? see below ๐ Finish was OK.. BUT
After leaving screwed down overnight a hairline crack had developed ๐ก
Pic 10. Also, I didn't like the 3mm fillets between the hatch deck and the main deck, and was wondering what to do about the lip on the bulkhead at the rear of the cockpit. There was a chunk cut out in the middle. This was where in the old days we had a tiller bar to set the rudder for Free Running on a great circle (Radnor Park Lake in Folkestone - side note for Graham P74, probably before he was born๐)
Sooo .... machined the lip away, removed the 3mm fillets, made a cardboard template for the new deck-piece and tomorrow is another day. Wonder what I can muck up then !!?? ๐ G'night all, ciao Doug ๐
Oh yes the Filler caps - drilled them on the lathe for 4mm thread clearance, dug out the tap set, selected 4mm 0.7mm pitch ..... Oh S..t, only a tapered tap which starts cutting at 5mm. Hole in the cap is only 5mm deep.๐ก Immediately ordered 4mm parallel machine tap, should be here on Wednesday. No sweat, should have deck hatch Mk. 2 finished by then ๐
