Default Broke My Bracket, now have to Fab, other considerations...

Sigh. First the standard disclaimer:

Anything dumb you see from me in this thread is the result of ignorance and I am learning. All advice and guidance is humbly appreciated.


Sometimes I wish I didn't learn things the hard way. Looks like I'm going to learn some fabrication skills one way or another...

Referring to the two attached photos...

As you can see here, the builder didn't use the plans-specified U-00713C Nose Wheel Fairing Bracket on this RV-6A, instead fabbing two brackets for holding the nose wheel fairing. Using the plans-specified bracket now would likely (but I'm not sure) result in mis-aligned holes in the current nose wheel fairing. I suppose I could do a new fairing...but...

In the second picture, you can see the forward bracket in my hand is cracked. Both sides are cracked in a similar fashion, and while I don't know for sure I'm pretty sure I did this when I lowered the fork onto a wood block once I removed the nose wheel to send off to AntiSplat.

Anyway...they'd probably be okay, but I try to do this stuff right, which means I need to fabricate new brackets.

This looks like a simple job for someone who knows what they are doing. Alas, I do not, but I recognize that this might be simple enough for a newbie to muddle through and learn a few things.

So. I'm going to go back to the "basic riveting tools thread" and figure out what I need for this. My question to you fine folks:

What kind of aluminum stock do I need to order for this, and do you have any specific advice on how to go about making new ones, using these as templates, knowing that I've never made something like this before? I'm optimistic that I can do it, just need a nudge in the right direction.

Thanks in advance.

Default This is the old style.

Those most likely aren't home brewed parts. That's the way the nose wheel used to be. My 7a has that arrangement from 2003.

The parts you want are:

U-813D-L PR NOSE FAIRING BRKHT $5.75
U-813D-R PR NOSE FAIRING BRKHT $5.75

Looks like they are still available from Vans. Those are the front bracket part numbers - Left and Right respectively.

The rear parts are U-813C L/R .. but they don't appear to be available anymore.

What Ron said; your brackets are what were formerly used. I switched over to the new style on my -7A without too much trouble and found it to be a superior attachment method. Donít remember the details now, but give Vans a call and Iím sure they can get you set up.

Thanks guys. That's super-helpful. I'll definitely check into getting those brackets. I just assumed (haha, got me again) that they were home grown because they weren't what was in the plans.

I do like the idea of converting to the new ones but I suspect the holes are in the wrong place. Maybe. I'll talk to Vans.

A local mentor has offered to weld them up for me, but at a couple bucks each seems simpler to obtain new ones.

When you get the new brackets please smooth all edges well. If you do not do that, you will find that they will crack as well over time. Edges not smoothed are serious stress risers.

Thanks Erich, that's helpful.

How does one tell if they have a new-style or old-style fairing? I didn't seen any numbers or identifiers on mine, and it's not clear from looking at the plans on the USB stick (C1) or any of the older versions.

FYI: 2024 not weldable in any reasonable sense.

Extra holes in fiberglass are super easy to patch with a little epoxy and flox. The hardest part will be matching the paint after you've patched the hole.

Good to know. Might be interesting to upgrade just to teach m'self a little fiberglas technique.

I wonder if there are any basic fiberglas kits/projects out there designed to teach a little bit about it, the same way Vans has the toolbox kits?

Vans tech support was very helpful and gave me some guidance about this - the original bracket type that I have has apparently all but been stricken from history. I get the idea about upgrading to make things easier in the future and maybe that's something to consider. Gives me an excuse to consider changing some of paint scheme via the nosewheel fairing....hmmmm....
