I have a couple of bows and an adjustable power source. Have not cut cores before though.
I could bring it over and try it with you or something.

I have quite a bit of experience cutting wing cores using the bow and template method. What do you want to know?

Rob, are you, moving closer to Guelph anytime soon?

Kidding aside, when is the best time to hook up? During the week or weekend?

What kind of template do you need? The chord is constant, no taper. 24" x 3.75", 18%

Are you coming west in the near future?

Anyone have foam wing cutter setup for sale?

Hey Alan,

I didn't know I was volunteering to cut wings for you!

I make my templates from 1/8" aircraft ply and sand the heck out of them. It's best to have a lead on and trail off area so the wire doesn't get left in the foam when you stop. You need a template at both ends, in most cases, and a second person to hold the other end of the bow.

No way. Perhaps if we lived closer.

Ken Ross volunteered to bring his cutter gizmo over, but I don't think he knows where I live.

It's nice to know what's available.

I was cutting wings last night. The cutting itself is pretty fast and straight forward, but it's the set-up that takes time.

Why don't you set something up yourself? That way you can cut whenever you like. It's pretty easy once you have the gear. You just need a current adjust device of some sort. A model train transformer? A dimmer switch? I don't know. I've always used an Astroflight Ni-Cad digital charger with the current adjust knob. Mine died years ago, so now I'm using Ben's... I'll give it back eventually

I'll take pictures of my set-up tonight and post them here tomorrow for your reference.

Thanks Rob. I'd like to see what's involved.

Pictures Rob?

Whoops! Sorry. I've been busy.

I'll try to get them on here tomorrow

A fella from Australia sent the instructions to make an automatic foam wing cutter. It's a home made version of the Tekoa Feather Cut. Will try my hand at making it after flying season.
