Log Book
spent 3 days working at alloy yachts helping out the tradesmen,
wednesday i started out sweeping and moving laquered doors and panels for the guest bedrooms these were made of a teak veneer and a light brown stain with a clear laquer finish over top, also had to check the panels for runs and air bubbles so they could be returned and re-done , they were really fussy with the quality and i had to be extra careful with the components.
after i had moved all these i went inside the AY41 yacht which is a 63m power yacht worth 120million. I was fitting 7mm ply around the top of the galley units for the corien tops to stick to also to help position them. (i asked what the corien was made of but all i could get was that its a type of acrylic - dense plastic) but i will look into it with more detail along with a few other things.
that pretty much wrapped up my first day there it all of the workers i met were really great to work with and had alot of time to share what they know and answer any questions i had.
thursday i arrived and got right into the pre upholstry shop where the guys were making seat frames for the upholsterers to upholster leather onto them. the 3 seats i was working on were some ones mistake they were 7mm to small on the width and when they were pre-fitted on the yacht thay had a 21 mm gap on the edge which stood out like dogs ___s so i measured up and glued a piece of 7mm ply on to the end of each unit . i made them about 10mm oversize so i could use the trimmer to make it flush all around, i then had to make a trench 20mm from the edge so the seam from the leather could slot into it. wasnt aloud to use the big router so it took me twice as long having to do 3 passes for each side beacuse the small trimmer couldnt handle the 8mm deep trench in one go. never mind.
after this i went into the veneering shop and i was cutting backing veneer for the panels in the galley these were all visual panels so the backing veneer wasnt going to be seen. Im not sure what type of veneer it was my guess is a teak look a like he said the sheets were about 10buks each and the good face sheets about 50buks this was a simple job to do as all i had to do was place the panel of ply on to the sheet of veneer then cut around it and tape the cut piece to the ply so it could be pressed later on with the face sheet.
friday
i was set to work with a man whose sister is a good family friend of mine i had never met him so it was good to do so, i was it the AY43 yacht fitting the soles.
the entrie yacht was sitting on foam core between itself and the aluminium this helped with the sound proofing of vibrations etc. so we had to be carefull that the resin we made to hold the sole wasnt to thin, so it wouldnt run down and bridge the gap between the sole and aluminium, this would eventually snap and squeek when walked over and if you spend 120milllion on a yacht you dont want a squeeky floor, they were using a summertime resin which goes of slightly slower than the resin we use a unitec i noticed this because the hardener looked alot lighter in colour, almost looked thinned out.
i had to use the grinder witha sanding disc to sand the epidure off the timber so the resin would stick to it, (apparently resin doesnt like sticking to epidure)
we then brushed the resin with microballoons onto the timber and placed the sole down, screwing strongbacks to make it flush with previously laid soles.
we then set about fitting a bulk head this took us 5minutes because someone had already prefitted the bulkhead. it was for a panel to be scewed to that held wiring for the sound system.
after that i went to the cabinet making shop to help out and i ended up making some triangle shaped and circular shaped plywood these were for yachts to raise up their mast i think to signal something.. will have to look into that aswell
that pretty much summed up my exp days i really enjoyed it and wish i had done the whole week but a funeral had me in hawkes bay since last thursday until tuesday
28th August
This week I started fitting the spacer for the foam core on thee cabin top I cut the pieces for the corners out of four by two then band sawed the shape out to fit the curve on the back edge, I the started to get a rough idea of the shape for the back edge of the cabin top. I then marked a grid on half of the edge and took tick stick measurements and transferred them to my lofting paper and lofted the shape and faired it further. After this I selected my yellow cedar to cut My scarves I had to scarf because a simple but joint would snap over the curve of the cabin top. I scarves it then I used resin and glue powder to join them I left it over night to go off. The next day I used the process of lifting frames off the lofting floor to get my shape and then used the bandsaw to cut it out then steamed it to the curve of the cabin top.
30th August
Today I started with the hatch frame packers i cut them out of 14mm yellow cedar offcuts that I found under our hull. I had drawn a shape o to a piece of a4 paper the I used the nail process to pick the lofting of the table them cut and sanded the shape to size. I then used it as a template to mark the others , enough for 2 hatches. Afte that I continued to shape the cabin top packer because it didn't have enough shape to it, I fired the steamer up and while I was waiting I cut eight slots where the curve had the most loadto help it follow the curve . One of the cuts split slightly so I had to repair itthen I could steam it And shape it without a hardpoint in it.while I waited for it to steam I helped mark and Scott clear of the resin that hadn't been mixed properly on the Coving around the edge of the cabin top. The ratio of the mix had been mucked up buy the hand pump locking up and not putting it out into a 1:5 ratio of hardener to resin. I've also been watching the guys work inside the hull on the flooring and they have bee. Going well until then mucked up the actual floor panel. TheyMeasured between each station which had a 20mm packer on each side and that meant thatthey were 100mm out. It also had curve which didn't fit becuase the length of the curve was too short
31st August -- 7th September
Today came in a bit late and started working on the backnof the then cabintop I clamped it into place the added nalis for pressure, the I cut a scarf into each end so I can fit the corner onto it then I shaped the window packers to suit the corner bracket and mucked it up first time round but it took me five minutes to repair it. I help mark marshal pit some lines on the fored Coving of the cabin top. So he could fair it up , while he worked on that gabby was fairing the aft end of the coving and which was a solid piece of timber that he could take away to fair. Richard was supposed to bring the hatches in for me to look at so I can accurately make the hatch packers. I've been watching jimy and fish assemble their flooring in the aft of the hull they have a good shape and it's all fitting well. The guys inthe fored are slowing down today becuase a few people are away And some have left while we were working. Slack buggers. Jeff has been working on the back deck edge of the cabintop and has got good lines. I think he has got a hard taskcoming up for when he has to cut the excess off. All the new coving around the front edge of the boat has gone off and is hard luckily we noticed it was bad yesterday or we'd be in shit!!
Made a sketch of the cabin top edge near the port port so mark and I can centre the port between the two coves, the ports had been pre fitted by Jeff to suit Richards requirements but after we drew the diagram to get a better idea we found it was out by 5mms 5 to high and 5 to far foward. We now have to wait for Richard to check our drawings so we can adjust them accordingly. I also sanded the Coves slightly so we wouldn't lose much of our resin sealer if we sanded them after we sealed it all.
We cleared off all of the window frames and the back of the cabin top then sealed the entire cabin top with two coats of resin and hardener .
We then started to clean tha back of the cabin top so we can store all of the accessories and they won't get lost.
14th September
* We are worrying about the hatches as of yet we will wait till the end product to fit them
Few tools have been stolen
Today we are cleaning up the cabintop and about to spot fill dents and cracks mark m is mixing the bog up and then we need to seal it again today then we can be ready to dura tec over the entire mould tomorrow after the theory lesson none of us can really be bothered but it has to be done maybe after we have spot filled we will have more motivation to carry on after lunch, Ray is helping Scott with the anchor bay in the front end ofthe hull Ed Han and jming are COBE the window frames
Mark me and Scott braver have set up te scales and tested them to make sure they are accurate and we are now checking that all the duratec is mixed to save time tomorrow as we only have half a day to get it fully coated we have worked out we need 2% catalyst which is the peroxide and test out the weights of the duratec to have the accurate measurements fir tomorrow also to save time.
We have set up a small wall to stop over spray hitting thenother classes boat c foto. We will roll resin over cabintop this afternoon to seal it all thentomorrow we can sand off excess resin an filler and when we seal the too we have to makesure that there is no runs to save work tomorrow.
Went through the work and checked there was no runs on the cabin top. All checked out pretty good and tomorrow we can attempt to do the final sand and then spray with the duratec.
