Scale Nelitz 1/3 scale Cub build

[dhal22]

Working on the cabin area tonight. One definite is connecting ANY wood to steel requires more than Hysol/jb weld. Tried that.... I'll run a screw through the 2 materials as well as jb weld or Hysol. Pin is a temporary holder.

Looks like it will be a little tricky!

Another step on the upper cabin area. Now to work on bolting the wood riser to the frame below.

Maybe a 3mm x 13mm pan head. Amazon will deliver a multipack later today.

Bolts aren't far away......

Here but the smallest screw which is all I needed unfortunately is too big. I will have to order the next size down.
2mm I guess.

A 2mm screw will be about the same size as a #2 servo screw. That is a weak spot on planes like the Cub and Champ. My Champ cracked in that area on a harder than normal landing, ended up milling a slot and epoxied in a 1/8" piece of music wire, did both sides, thankfully it is hidden under the aluminum trim piece. I would consider drilling the wood for 1/8" piece of wire with grooves cut to grip the epoxy.

Ordered some M2 machine screws, here sometime late this week.

 

[dhal22]

Much better. M2 is the correct size. Tony, I agree, this is definitely a weak spot. I will put more thought into this before I assemble.

At this point I think this joint will be as good as I can get it. Bury the screws and butt joint in Hysol, counter sink the higher screw and grind the lower screw head and move on to the next step.
