A Question For 'Tunnels'

[tunnels]

ding,ding,ding. Folks ,we have a winner all the way from bc canada. Even with no glass experience he got it on the 1st try! Thanks for clearing this up whipper.

so after all that prewritten rubbish you think bonding naturally is telling you how it is saving you resin?? Its not telling you a single thing of how !! So how is it saving you resin what is happening ??? . please Discribe bonding natually in detail !!! Give with the details dude !!

IT HASENT CLEARED UP ANYTHING ! ITS LIKE you SENTING A LETTER to someone in a foreign country WITH NO ADDRESS JUST A PERSONS NAME !

Have you ever written a instruction manual for doing or making something ?? This is just like that, its instructions with detail that's completely missing as in non existent !

Your post makes no sense. Whipper solved the saving resin conundrum. He gave a good answer. Next question...

Its only a small part of an answer yes BUT its tell me nothing !
WHAT IS NATURAL BONDING ??? THAT AS A ANSWER IS JUST THE HEADING OF THE DISCRIPTION AND IS EMPTY !, THERE IS NO EXPLINATION AS TO HOW IT BONDS NATURALLY PLEASE EXPLAIN!!
Present instructions as step-by-step procedures.

Keep studying on the problem, you will figure it out. When you have an answer, don't tell anyone. It's a secret.

Wow....I agree with the Whip, this is fun to watch,read as I am tryin to learn something but can't stop laughing! I would compare the layers dropped into the layup without drying between layers to painting. The more dry time between coats the larger build up and more material used. JME( just my experience) Gary

Tunnels ... capillary effect.

That is all.

Google it.

Once again... Unites States nuclear submarines. I know more than you. Just sayin.

And going back back to an earlier post... since when is a 22 foot boat considered a YACHT?!

Yip me to about the same era !, that's right and if its played with thought and care and knowledge the savings can be significant in some cases !!
Like 20 kgs of resin on just one side of a 22 foot yacht! still used the same glass laminate and amount of glass but laid all at once !!so we saved the guy 40kgs of resin !! and all that weight as well ,plus now days using the same technique but using stitched fabrics instead of 18 oz woven the saving would be even greater !!

SO COME ON YOU GUYS WHY CAN SO MUCH RESIN BE SAVED ?? HOW IS IT DONE ???

RESIN capillary effect is just common old resin infusion!

And a boat when it has a cabin, a galley ,a toilet ,sleeping for 4 adults , has a mast and sails spinnaker and a fixed cast iron keel ! It is called a yacht !

Thanks Webster

The word yacht is very very misleading ,Here all boats over 25 feet are called yachts . so you really never know what the hell people are refereeing to .

I think i know how this thread works now

Resin saving can be done when laying ,4,or 5 layers or even 6 layers of glass one after the other in quick succession and rolling each layer with laminating rollers BUT it has to be thought out before you start . you need all and everything sorted in advance , glass cut and rolled up and placed close by where you will be working being totally organised is the key so no time is wasted . Like I have pointed out many many times the resin manufacture has a lower limit of catalyst that you should never ever go below AND IT USUALLY .75% SO THATS WHAT YOU START WITH !! Using the low catalyst allows you time to get the glass laid and wet out and rolled properly so if you have 6 layers you can process and get 5 layers down and rolled properly !!The 6th and final layer of glass you can bump the catalyst lever back up to 1.5% on the final resin being used .
This will kick off and start to gel in the usual time frame and the warmth from that will assist the other layers to gel and the whole laminate will get nice and warm !! and it will hold its warmth for quite a long time usually as it warms the mould as well so its curing the lay up at a much higher temperature that would usually happen and for a much longer period of time . Resin saving can be quite significant on big jobs, the wet on wet layers and the rolling out with laminating rollers compresses the glass fibres much tighter together than you would normally get and so the glass to resin ratio is much higher than you would normally get !

As I said all this has to be well thought out and properly organised before the job starts , timing is very important and knowing the gel times of your resin at different ratios of catalyst . using the natural exotherm warmth from the resin helps cure the whole job . I have used this method many many times on big boats when they have cores in the topside only ,so the core is laid into the wet glass and then the top layers of glass over the core are laid all at the same time I have shown a lot of people and it works wonders !! !
