Hi,

After watching ALL of your tutorials and reading forums for about a month now I am going to make a petrol tank for the bike. Along with the fenders and belly pan.

I have decided that the tank mould needs to be 5 part, so as to avoid mechanical lock. the base would be one part and the main curvy bits would need a four part mould. I would then glue the base to the top.

My question is this; Would tack spray be enough to hold the five layers of CF,Kev in place where the mould almost turns in on itself?

(I would like to use the infusion method so the CF and Kev would be laid in dry at first, so I was hoping the tack spray would do the trick)

The top part of the mould (the four part) has a section where there is a flat flange surface that I need to glue the base to when finished.

Naturally for some sound advice I would buy all consumables and infusion kit from here

Thanks in advance

Hi, If you are new in composites I would suggest to begin with easier and safer projects. Making a Fuel tank is a bit tricky and needs the proper materials, knowledge and experience, otherwise it can be a waste of money and further more dangerous.

Thanks, but you haven't really answered my question, only questioned my intelligence.

I know about ethanol and it's corrosive properties, and there are many solutions to that problem.

My question was about tack spray, and if it would interfere with the infusion process by using it on all layers where the fabric wants to fall away from the mould.

Hi, I didn't questioned your intelligence I just advised you to re-consider making a fuel tank just for safety reasons if you're not experienced. Since you've watched all the videos and tutorials you already know the answer, worldwide tack spray is used to hold the different layers of materials before infusion.

Another tip is to cover the inside of the tank with a special epoxy sealer for fuel. Good Luck - Peace!!!

Thanks for the advice. I just thought it might interfere with the infusion process or affect the surface finish. I will use tack spray.

Any recommendations as to which one?

small amounts of tack spray will be fine.

And it would be sensible to use a tank sealer/lining "rubber" coating. plenty available in the classic car and motorbike scene. Some even for plastic tanks.
