Plans-building CH 640 Question: How long are the longest bends?

Good day, all. I am currently in the midst of plans-building my 750. I broke my bending brake on some of the thicker bends, and I am currently rebuilding. Since it is currently only 8' long, I'm…Continue

YouTube Channel for my build log

Hello Everyone,I thought I'd let everyone know that I've been working on a YouTube Channel for about 2 years now for my scratch-built STOL CH750. I'm no video professional, and certainly not a professional builder. My channel chronicles the struggles and successes I've had, along with bad ideas, good ideas, etc. It's part builder log, part how-to, part "an afternoon with Greg in the shop."Anyway, I started making videos to help other beginner builders when I couldn't find much on YouTube about…See More

Background Info:
Originally started building a 601XL, and finished the rudder at the factory workshop. However, some things in my life changed (including getting back into backpacking/camping), so I decided a STOL aircraft was more appropriate. Still finishing up my Chevrolet Corvair engine conversion, and hope to install it in my 750. Just getting started on my 750 tooling. Starting from plans for now, since it is my only option financially. Perhaps my financial situation will change in time for me to build more quickly with kit parts. I am also a member of EAA Chapter 55, based at Mason-Jewett Airport (TEW) in Mason, MI. Hoping to learn, network with others in the Zenith community and have fun.

Solid Riveting

Posted on March 9, 2016 at 6:46pm 11 Comments

Well folks, I've made a ton of progress since my last post. I have the cabin sides ready for solid riveting. I'm also ready to start match drilling the wing spar pieces. I've made about 75% of the parts in the plane. About 3 weeks ago, I broke my bending brake trying to bend some longer .063". The pop rivets holding the piano hinge pulled out. So, I thought I'd use the opportunity to practice my solid riveting by repairing the brake with bucked rivets. What a disaster. I simply CANNOT get…

More progress!

Been hard at work on things. Fine tuned the bending brake, been shooting video of my progress along with Tips & Tricks. Got a lot of channels bent up and many other parts. Check out & Subscribe to by blog at http://gregsplane.blogspot.com for regular updates & videos if you like. I'll keep posting certain milestones here though!

Eastwood Solid Rivet Guns

Posted on October 27, 2015 at 10:53am 3 Comments

Anyone ever use an Eastwood Rivet Gun? The company claims that it is about the same as a 4X gun. Since it's so cheap, I thought it could be a re-badged air hammer, but it sounds like a rivet gun in the YouTube videos.

Bends are a success!

Finally got my DIY brake set up properly with enough clamping force to get the .032" bent! Did my rudder spar & spar doublers, and actually got the rudder skeleton riveted together with Cortec CpVI-373 on the mating surfaces. I'll be working on the skins now.

Hong should be hinge...lol

I just located the Dave break material list. So it was stainless steel. I've not seen all your bending brake videos so maybe you've answered this already. Do you think a heavier gauge piano Hong might do the trick. I see you went with a metal hinge.you may have already looked into it but I was thinking of calling around to some industrial supply places to see if there exists a very heavy duty piano hinge that would work

I was wondering about the Dave brake. Did it use aluminum hinges and if so do you think steel piano hinges would work better or make a difference

I wanted to mention something about the CH-640 that I dont think has been floated around before. If you really wanted 4 guys to ride in comfort. The rear passengers could be turned around to sit back to back with the front seat. This would move the CG forward for the rear passengers and you could then then probably safely put a foot well area , making the rear passenger area more interesting. 

I saw this Idea on the Bearhawk site, as some there have converted that plane into a 6 seater in special circumstances and also to improve cargo CG if flying as a 4 passenger.

The construction standards book I got with the CH640 plans is dated 2002, I downloaded a more recent version dated 2011 is that the date you have?

Maybe they send the old version for nostalgia sake..lol

The question I was wondering about is in the general tolerances, in my new book on page CS #300 top graph . Is it saying youre allowed a 3 millimeter error over meter distance? and the bottom graph on same page us just the exceptable error over larger distances?

does the small l = length

I just want to make sure i`m understanding this part.

so bottom graph is saying you could be off by a centimeter over a 8 meter distance?

not that I plan on being that far off but I just wanted to confirm Im reading this right.

I saw your chat chat out. You been a huge help. I went online and bought the Homebuildershelp videos 

-Basics of scratch building, they build a 701 rudder parts from scratch

-Metal working 101 they put that rudder together

They even tossed in a free video - How to build an RV7 tail kit, but Ive been there done that so didn't watch it.

One thing they left out of the videos is how to drill the Rudder skin to match the rib layout. The metal working 101 video uses a pre-punched skin. so I never get to see how a blank rudder skin gets drilled out.

Do you know of any good videos or literature that covers that. Taking the blank skin and matching it to the rib skeleton.

Hi Greg you've been a huge help so far in pointing a new scratch builder in the right direction. Got another question for you and I should be good for awhile...lol

In my quality standards book that came with the plans it goes over the exceptable limits for errors in construction and has a number in the triangle. To this point i`ve just banged together metal from kits like my RV-7 so this is new to me.

Have you covered this in one of your videos or can you point me in the right direction to someone that has gone over this. I really want to get a good handle on it.

I saw your video on cutting out 0.063.  Have fun bending 75-F-3-6, 75-F-3-7, and 75-F-3-9

Hi Greg, 

Very nice work you are doing here. I think there is a file attach option here. If you prefer I can send you my personal e-mail ?
