Haines Signature 1850L Rebuild and Refurbishment on going project.

[burleygu]

Little bit of stringer work this afternoon. I took some photos of how I go about getting my stringers cut to size/shape. I mark the hull in 200mm increments and then I measure from the top of my newly installed stringers to the LOWEST POINT of the hull. This ensures I have enough material on my stringer to sand/plane off for the taper of the hull. I write down all my measurements and the fluctuate quite a bit. This is due to how much fiberglass I removed in places when I sanded the hull other bumps high spots etc. when the hull was manufactured. I transfer this all onto my ply marking out the ply in 200mm, then its just a matter of joining the dots and that's your stringer. Cut it out and you have a roughly cut stringer. It then goes into the boat and you can mark out the areas were you need to remove material etc. to make it sit more snug to the bottom of the hull. You can see my marks on my ply match up with the marks on the hull and for a rough fit there is nothing more then a 3-4mm gap anywhere. Once sanded and tapered it will fit nicely. You can also see how my pieces are going to fit together with the 250mm overlapping joins. I'm sure there are better ways and different ways to do this but this way works for me with what I have and I've been getting good results.

Adam Ill be a little while yet before I glue these suckers in as I have 2 more to cut out Chance Ill be gluing them in sometime on the weekend!

Thanks Mate, these are the tips I need. Still real keen to see the taper to match the hull and gluing process (poly resin or epoxy??)

I've got half the hull sanded to P320 with abranet and guide coat, if things go to plan, finish sanding and spot prime on the weekend ready for top coat the next weekend.

Adam here is the run down on how I have been gluing in my stringers. Im sure people do it differently but this is how ive been attacking them.
To make the glue/paste/peanut butter/filler whatever you wish to call it I simply mix talcum powder with the resin until it turns out like peanut butter hence one of the names. you can use Johnson's baby powder normal talcum powder or you can buy talc in bulk in 20kg bags. You mix the resin and talc before you add the hardener. Someone mentioned about adding fiberglass shards into the mix to give it more strength. I agree with this if you were using it to fill holes etc. But the main focus for this is to use as a glue/filler which doesn't need to be structural as the stringers are getting fully encapsulated in fiberglass. I apply it liberally to the bottom of my stringers tapers etc then flip it over and press it into place. Once its positioned I use the over burden or left overs in the tub to form the ' fillet ' along either side of the stringer this fills any gaps and gives the fiberglass mat a nice curved edge to bend around rather then a sharp angle. Once its dried it needs a sand before you can fiberglass over the top just to ensure the glass bonds well. It dries solid as a rock as its mainly just resin the talc is purely to thicken the resin so its workable.

Looking great Tim!

Thanks Mate I understand what you mean. Are you using polyester or epoxy resin for the glue??

I'm geared up to paint my little project this weekend, will update that thread once done.

Thanks

Have not had much to update of late. Mainly because there has been stuff all achieved, The stringers in the right side of the boat have all been glued in. However the project has taken a little turn. More on that later.

The pushing issue atm. Is to get the trailer towable. I bought the boat from tin can bay and I opted to have it bought back to Brisbane on a tilt tray because I wasn't comfortable towing it. The trailer frame has been home made and to there credit they used nice heavy gauge C channel. However some of the welds to me are to cold and did not penetrate into the steel well enough. You can also see the angle they have welded down the center of the trailer under the cross members, when the boat is on the axles hit the angle and the trailer basically has not suspension as the axles hit the frame. Also The trailer needs more bracing in areas as well as the mudguards strengthened. It also appears that when the previous owner built the new trailer frame they re installed the cradle (springs axles wheels) backwards? What are your opinions on this? The 'eye' Of the springs is to the back of the trailer and the 'slipper' part is to the front. As far as I knew they are suppose to be the other way around?

[burleygu]

Trailer has had bracing welded over all the joins and the cradle has been removed ready to be spun back around. Hopefully have enough time tomorrow after work to get a few bits and pieces from the trailer shop then give it all a bit of a sand and a fresh coat of paint and re assemble.

Burley you can lay your fibreglass wet on wet with your bog mix if you like. Saves the sanding step.

[burleygu]

Yeah thanks mate I realize that. I never have the time to end up fiber glassing straight after I bog down the stringers As most of my work is done in the afternoons after work and its getting dark pretty quickly lately! And a 6mtr long stringer is a lot to glass in with only your own set of hands!

[Rip it up]

I know your pain burley. Try working 13hr days with 3 project boats in the shed. I have really good Neighbours that let me grind until 7:30pm. Then its resin time after that.

[burleygu]

well I have horrible neighbours that insist my power tools are faulty and it distorts there tv signal. But has absolutely nothing to do with there tv antenna being right next to my shed and point straight across it!

[tropicrows]

Tim, solve that problem by giving them earmuffs and run air tools and bloody big compressor ....

[Nathan Tuskes]

dunno if its mean mentioned or not but i always found it easier and rememberbeing told from someone in the game to mix the resin and catalyst first thenthe talc or whatever filler your using that way its alot easier to get thecorrect mix right thru the batch then mix in your filler. i remember thosenights where i was up till mid night glassing in stringers..

[burleygu]

I have a glorious little plan that will resolve all of my issues hopefully by the weekend! But Bruce! I love your idea! Bigger compressor hmmm

[burleygu]

So doing a bit of the work on the trailer each afternoon and she is basically done and fully refurbished. I still need to put brakes on which I would of done this weekend. But Pro bar at caboolture isn't open on a Sunday so that will have to wait. As I need 2 new hubs with discs. Calipers and cable. I could get them from super cheap bcf etc. But its so easy dealing with the guys down there tell em what you want and they box it up for ya and you get home and the parts are actually right!
Will be putting the boat back on today then taking the old girl for a little drive!
