Yes Kevlar "fuzz" is a real pain! I've used thin CA to contain it, but a layer of glass over the top is better. And then there's the challenge of cutting Kevlar cloth...because I'm too mean to pay £40 for a pair of scissors. Mind you, it is bulletproof. :D

Ooops! I'm blaming auto-correct. ;)

I keep meaning to find out what's special about Kevlar shears, I have some and they don't look any different to any others scissors.

They do the job. One thing that I found helped with cutting was using spray adhesive on the cloth, leaving to cure, then it seems to cut easier.

Time to stop procrastinating - wing joiner construction;
2 lengths of pre-aligned carbon tow, 50mm wide (folded over double), the ballast tube construction and cut lengths of carbon tow.

I used way more than carbon tow than shown!

All assembled into the waxed & PVA'd mould. Now I'll have to wait till boxing day to see if it was a success (or not😥).

Merry Christmas all.

Successfully came out of the mould, without any bother. Just needs to be cleaned up and cut down to size. Weighs approx. 130g.

Fantastic work, Martin!

I'm sure there's been a fair amount of head-scratching, but you do make it look so easy - "Oh, I'll just design my own version of one of the latest glass super-ships. In rib-and-stick construction, to boot!"

I'm following your build with keen interest - may we use the plans that you shared?

Best wishes and a (belated) Merry Christmas!

Hello Marian,

Yes lot's of thinking time for sure.

I shouldn't sing the praises just yet, not until it has successfully flown and landed. But you're welcome to use the plan (CAD also), but bear in mind it's no Chris Williams plan :D - lot's of mods & adjustments will be needed.

Hi Martin,

Thanks for your prompt reply. Yes, with a fair bit of experience under my belt (OK, mostly a LONG time ago) I understand that a large chunk of any plan build is in the details and the bits that don't involve carving/cutting/gluing balsa or other material :twisted:

You mention CAD use of your plan - could I ask you for a DWG or DXF version of the plan file/s? I'd like to enlarge it to 1/4 scale and naturally will share it back with you.

Cheers
Marian
