Re: TX18+10%. Change of material thickness for ribs

Thanks onewaytraffic. I do mean frames. I agree the +10% is already adding alot of potential force, that's one of the reasons I added 2 frames to reduce spacing. Plans call for Approximately 920mm spacing, add 10% is over 1000mm. I reduced to Approximately 830mm.

TX18+10%. Change of material thickness for ribs

Hi guys. Busy installing the stringers on my Build. Running low on 3/8ply for the ribs but have lots of 1/4 and 400gsm glass. (I would have to import ply which is a pain). I have adjusted the ribs placement from 1005mm to 830mm so adding 2 in the build. My question is: is it safe to substitute the 3...

Re: Nidaplast 8 laminating schedule for TX18+10% sole

No worries Fallguy, the whole point for me being on the forum is to learn, I appreciate the fact you checked. I agree, the Nidaplast does appear to be a great product and easy to use. I saw a video out of the UK by Easycomposites.co.uk (How to make a carbon rear wing) where they used Nomex Honeycomb...

Re: Nidaplast 8 laminating schedule for TX18+10% sole

A serious DUHHH moment. I used beam width from transom to bow! :-? :-? :-? that was my mistake, making a huge sole and worked on 800gsm glass + epoxy. Rough estimate is actually about 14m2 including front deck, and 400gsm of glass and 400g+20% epoxy for hand layup and soaking the ply. So saving is 2...

Re: Nidaplast 8 laminating schedule for TX18+10% sole

Glad to see our sums are the same! When I ordered the Nidaplast my supplier said to add about about 10% max to my epoxy needs for the scrim soak up. I did, and was left with alot of waste epoxy. I made sure the Nidaplast was dripping wet, added pre wet glass, then more epoxy, and finally rolled on p...

Re: Nidaplast 8 laminating schedule for TX18+10% sole

Hi Peewee and Fallguy. I am using Nidaplast 8. The honeycomb is sealed with a membraine, so there is no chance of loosing epoxy / resin into the honeycomb. I have double checked my weights and allowing for a minor variation in surface area (a few mm) I calculate that the total amount of epoxy used w...

Re: Nidaplast 8 laminating schedule for TX18+10% sole

Thanks guys. I will make sure I rotate the Biax so that get tows aligned as advised. I did not do this on the sample. I retested the sample for flex again today, and it has stiffened significantly. I will be going 800gsm top and bottom.

Thanks again!

Re: Nidaplast 8 laminating schedule for TX18+10% sole

Just a short update on the Nidaplast sole experiment, and thanks for the advice in this thread so far. A side note, I have no access to 1708 fibreglass here, and at this stage of the build have only 600 and 400gsm biaxial and 400gsm twill. I received my 25mm Nidaplast and cut a strip 700mm x 100mm. ...

Re: TX18 centre of gravity

Thank you all for your help and input. Before flipping the hull onto the trailer I placed a fulcrum under where station 'C' would sit and balanced the trailer prior to placing the hull on it. Interestingly enough the empty hull shell balanced near perfectly over station C when placed on the trailer....
