Supra Bits


Thanks Marcus.

Ideally I'd use the Nexor Pro pod/boom and V-tail combo further down the track.

In the meantime however it gets the Supra bits I got from Big Al.

Should have more done over the next few days. Waiting on 2mm carbon rod for pushrods then it's fit-out and fly.

How's Machine #6? going?

Hinges


First for me was cutting wiper slots and abrading the hinge underneath.

Semi-successful.

Wiper slot was a breeze but took several light strokes with the router so the bit wouldn't build up heat and melt rather than cut.

The semi bit was how the hinge line had to be shifted towards the TE so it wouldn't clash with the sub-spar. This meant the hinge sat plumb on an area where the balsa wasn't chamfered. This made the hinge hard to bend.

Remedied by relieving some of the balsa from the inside once I could get in there and sand some away.

The peel-ply (Abresegwebe sp?) seems ok and the hinge is solid. Having the hinge so close to the sub spar does that. There's ony 7 mm from hinge to sub spar.

Hints on abrading the hinge from underneath; don't bother laying down masking tape, just cut into the paint. The Dremel disc works well.
  • 20 strokes it'll go through the paint and 3/4 oz 'glass
  • 20 more strokes and you're through the carbon.
  • Stop when it goes a lighter shade and the pitch of the cutting action goes up. That's when it's hit the peel-ply.

Next up; do the other 3 surfaces then wipers.

Wip


Other flap done.

Previous recommnedation to ignore masking tape while scribing hinge is wrong.
Use it.

Peel it off once you're past the paint and veil layer though. The remove the guide alum angle and go freehand so you can better "feel" when you hit the peel ply.

Junior Saw from Bunnings was $5 well spent. Hint: prime the cut first with scalpel so the saw doesn't wander.

Next up; beer o'clock!

Slots done


All slots done.
Resorted to ball router bit because the wing depth tapers to a very thin profile and the other bit would have gone straight through.

Finish sanding slots and working the hinge then servo bays next.

Bog Wipers


No. Bog mix. It'll be a 1st for me.
I'll be relying on Steve's expertise (he's the bog wiper master) on this one.

hang on...bog wiper master just sounds plain wrong ;0)

It only just occured to me after looking at the photo of the Junior Saw ploughing its way through the wing; it might be a better idea to use the dremel cut-off disc to scribe the line THEN use the Junior Saw. That way any chance of paint flaking is minimised.

Boggy has a ring to it, you could be onto something...

Chris.

ps. re: The picture of the sweaty gent with the gun...there IS a connection to the thread's evolution you know...1st one to get it gets an extra special nickname.
