Zenith CH750 Wing Attachment Prep (Ep93)

[@flyingkub]

In the RAF we never used the same abrasive for steel and aluminum as it causes corrosion, as the steel gets imbedded into the aluminum.

[@AnonyMous-jf4lc]

I was going to mention this. It’s often overlooked.

[@jimhumphrey]

I was thinking the same thing. I use a 2X72 belt grinder for that kind of grinding but there is no wrong way. Using the belt grinder lets me change a belt for wood, aluminum, or steel.

[@KitplaneEnthusiast]

Or you just reprint the wheel like I do. Everything doesn’t need to be difficult!

[@KitplaneEnthusiast]

Re-grind. Not reprint.

[@flyingkub]

@@jimhumphrey when we did use belts and just marked the backs with an A for aluminium alloy or C for copper base and F for ferrous.

Progress must feel pretty good about now. Consider flying one of those birds over to Pontiac on Sunday. It'd be great to see you there.

Hey Mark, I'm only 5 minutes from 9G2. Would enjoy the chance to help you with the Super Duty. I also have some questions about my 650 to run past you.

[@marksmith7896]

Nice work !!!!! Like !!!!!

[@wheelerdavea]

Boy, no wonder the grinder walks around. Did you notice how much the wheels moved when you started grinding. Looks like a set of bearings in in order. Sure do like following your build.

[@KitplaneEnthusiast]

Did you miss the part where I said it's sitting on grass?? The wheels don't move at all.

[@wheelerdavea]

@@KitplaneEnthusiast I meant the grinding wheels. When you touched the strut end to the wheel you can see the label on the grinding wheel move in and out. I should have been more specific.

[@AnonyMous-jf4lc]

Noticed this as well. May not seem like a big deal, but once replaced you’ll wonder how you ever used it before.

[@KitplaneEnthusiast]

Oh I see what you’re talking about now. The wheels don’t move although for some reason it looks like they do. Maybe something to do with the camera frame rates??

[@jimhumphrey]

@@KitplaneEnthusiast Yep, that's precisely what it is. If that shaft was moving as much as it looked it would short the armature. The vibration is in the grinding wheels. The best thing to do is to bolt the stand to the floor with some rubber spacers to absorb some of the vibrations. Or move it into the grass 🙂

[@flienlow6281]

get a cheap drywall lift for lifting the wing???

[@fivezeroida34]

I am in Dexter near Ann Arbor if you need a hand with the wings. I may be able to help you out.

[@coastalbbq1]

somebody explain what's going on with all these annoying ads on youtube. I watch with a laptop.

[@KitplaneEnthusiast]

You new to the internet??

The person making the videos is making money. Simple.

I hate it when my hangar floor is not poured level. 😂
