Itchn' for Scratch III: Republic XF-91 Wing-Half Re-Construction

The Challenge:

A good pal, SparrowHyperion, tagged an old classic for me, the Republic XF-91 by Lindberg, but it was missing the underside half of the Starboard wing:

So I decided to re-construct one from Scratch.

Here’s the part that is missing, or Here’s the missing part:

Lot’s of underside detail, holes to drill, wheel well covers, etc.

So it is easy enough to scribe it out of stock styrene sheet, maybe laminate, and carve and sand,

but no time, so I am using a proprietary method to replicate the form.

I started with a 1.5mm styrene stock, and traced the outline:

Next, I traced the outline to the underside, so when I ‘dish,’ I don’t go “out-of-bounds,” and then I cut it out and, of course, left lots of tolerance so when I sand those gluing-surfaces flat, the edges won’t retract,

right?..lol:

Next I started the ‘dishing procedure’:

This is the inside ‘dish’ profile I want to copy:

And so i ‘dished’ it a bit:

Here is what the edge-on view should look like:

Here is where I ended up after ‘dishing-it-out’ a bit, hey, bud,

if you can’t cut it pal, don’t dish it out…lol:

Next round, a bit of trimming, sanding, ‘nuance dishing,’ plotting the scribe-lines and holes, then drilling, scribing, gluing, but fellas, sorry, no rivets for now…lol…

Thank you for visiting, I hope this was helpful.

Tx to Tim!

How do you hold in that curvature? Doesn’t it want to spring back flat? Do you just overbend it?

Nice work! Looks good to me Dom.

Nice start there, Dom!

Creative, imaginative, and enterprising…
These are just a few of the words that I’m reading off the teleprompter.

DITTO!!! [dto:]

Dom wanted me to let you know, he’s having some issues getting on the thread to reply to anyone. He is trying to correct the issue.

Hi guys,

There was a glitch in the system. We’ve corrected it and everyone should be able to post without any difficulty. I’ll let Bockscar know via PM.

Thanks,

Tim

Many thanks Tim!

The glitch is history.

I have an update on the wing,

and will be sanding to final shape this weekend.

I would like to share the curvature method here, but thought I could share it with a larger

audience via Aaron’s ‘Reader Tips, Solutions and innovations,’ in their Magazine issue.

No rush, not many need to reconstruct a curved wing surface every day.

I found out the hard way…[:D]

With any luck, Aaron and FSM will let me share the method through the FSM Magazine, which, of

course, would be a great honor.

All the Best for now,

Dom
