You'll want some solid blocking to take the compression loads once carried by the standoffs.

Waco 1,

Agree. Not sure thru-bolting buys me anything over just using epoxy to glue box on. Unless the epoxy joint fails and the engine wants to depart. Even with blocking, this is still a soft joint with wood on both sides.. No advantage using long bolts to develop a good preload when torqued.

Instead of butt joints, I made finger joints on the electric conversion of my Cub.

David (Mogman) is down for monster planes he, as of yesterday has 55 flights on his 40% YMF. I got to crew for him and that Moki 400 will nearly drag both us around.

I'm coming up from Fort Myers in the morning. Will you guys still be there? I can be recognized by a long gray pony tail.

Bill, thanks for the information on how you plan to brace the stabilizer, do you by chance have any pictures? How did you flatten the aluminum tube?
Thanks!!

Stickbuilder

I put the rod inside the tubing and put them between a couple of boards. Then I whomp the board with a hammer until I get the desired shape.

Thanks Bill. I can do a couple of boards, I was having visions of English wheels, special forms and the like. I can do simple!

It is with great personal sadness that I must report the passing of John Livingston (Old Git) who has been a Brother since the very early days. He was known as Brother No. 14, since the Brits have no hash tag on their keyboard. He has been issued one of the reserved numbers and will hopefully use it proudly through eternity. John was an accomplished modeller, and metallurgist who was very helpful with the Waco Phoenix Project. John, farewell and light breezes old friend. You will be missed.

John Passed away in January of this year, but we did not hear of his passing until another Brother sent me a message asking if I had heard from him recently. I had to say that I had not, so he did some detective work and learned the sad news which he forwarded to me.

Had a great time at Monster Planes. The weather was great Fri & Sat with light cross winds compared to most years . A lot of great flights and some not so great. Here is a short video of Dave Collis flying his big green Waco.

It was my distinct honor to crew and call for Dave on Thursday and again on Saturday morning.

Looks like Dave really has the Big WACO dialed in.

YMF 1/3 Barth

As much as I hate to admit it, the 'suggested' engine mount provided on the Barth plan (first generation) was better engineered than the cigar box I made. (post 16825). My problem is I don't have laser cutter and can't produce accurate slot and tab designs. But what I have will work.

Hop--my tabs and slots were done on a jigsaw.

It is with great sadness that I learned of John Livingston’s passing, aka Old Git Brother #14.
John was a good friend.
He will be sorely missed.

Waco 1,

I understand what you are saying. Any open surface can be cut on jigsaw or bandsaw. On the Barth Waco, engine mounts (slot and tab per plan) protrude through firewall. I don't have a convenient means to produce these cuts. They are rectangular cuts completely through the firewall .Maybe 3/16 by 2 inch, 3/8 deep. Think of cutting a slot in the middle of a flat 13 inch diameter plate.Could be done by drilling a small hole and then using a scroll saw. But in my case firewall is already attached to fuselage.

I had the same issue when attaching firewall. Plans called for four rectangular cuts in firewall with fuselage stringers protruding through the slots. From an engineering standpoint, this method is much better than a butt joint since epoxy is better in shear than tension. For my project, I cut them flush and butt joined. Now I'm thinking of additional bracing to keep firewall on. Thanks for your comments.

The slots in the angled battery box (where the motor mount attaches) were made using a drill and Dremel tool; then shaped with a Perma Grit flat file.

Reluctantly selling out, wanted Brotherhood to be first to know. Hope that's ok to do.

Did everyone leave? Did someone remember to turn out the lights?

Bill, Waco Brother #1

I just turned my lights on, arrived home from Monster Planes on Sat.. Ran into some snow in S. Dakota, and some cold weather. Other than that, it was a good trip.
Many thanks to Bill for his assistance at the event. An honour to be helped by "Mr. Waco"
Thanks to Dan for posting the video.
The plane flew the best it has ever flown, good landings for all 10 flights (62 on it now) and the big Moki was hitting on all 5 cylinders.

It was good to see some of the Waco-ites (Waco-nuts???) down there, Bill, of course, Dan, Robert and Chris.

Looking forward to next year, although I'm finding the trip seems to drag me down a little more each time, getting older, I guess. However, my outlook is "do it while you can, who knows what's going to happen tomorrow" So as long as I am vertical and breathing, I'll be there.

Cheers,
Dave.
