How to make a carbon windsurf boom

Step 2 Tubes

The tube I used was a flexible hose with an inner diameter of 25 mm. The tube is cut over its entire length using a knife. This is necessary to be able to insert the glass fabric later on.
Also needed is a 12 mm silicone inner tube which is provided with fittings at both ends. This inner tube will be pressurized.
Both tubes are treated with release wax.

All the mould parts are now ready. The next step is to make the glass pre-preg for the core.
