Sanding back

Today I’m sanding back the tack epoxy to a smooth finish. I figured I probably shouldn’t have used as much epoxy for this stage as it’s not very strong, due to the micro-fibre filler that’s added to make it more paste-like. The final wraps will use undiluted epoxy along with sisal twine and should be the main force-bearing layers.

It’s messy work sanding this stuff back. You need to wear a mask as the un-cured epoxy is still toxic. Only after it’s properly cured, which takes 4-5 days is it harmless.
