Is this 1/8" ply required at hinges?

The plans show a 1/8" ply where the hinges go. That's with the hinges shown on the plans. Do I still need them with eye bolts using a large washer?

Hi Don....I like the idea of the Forstner bit. I'll have check that out.

AN42B eye bolts

I plan to use AN42B eye bolts for elevator/rudder hinges. It seems I'll need a grip of 1 1/8". For washers and nuts, I plan to use AN960-10 and AN365-1032A. Will that work?

Thanks!

Re: attaching post hinge?

I'm going to be at this point soon. I was planing to use AN42B eyebolt and just drill through the tail post. Should I anticipate a problem with that?

Re: Tail dimensions on plans

Thanks Ken. I thought it was 3/16" because the 1" thickness minus the 5/8" in the center leaves 3/8"....or 3/16" on top and bottom. 3/16" also seemed right since the several stringers are 3/16" and fits on the ledge (but makes no sense on the leading edge). Hmmm. I have the whole thing laid out with...

Are the dimensions shown on page 2 correct (for leading edge, main beam, etc)?

How to end the turtle deck

Just wondering how you ended your turtle deck. I'm using foam board to get the basic set up. I now have the boards in place still using foam supports. Keep them all straight? Bunch them together?

Thank you,

Re: Rudder Post/bar typo

I'll weld the bushing first, then drill into it followed the reamer. It'll be interesting to see what it looks like when I'm done. Won't be much left I guess.

Re: Rudder Post/bar typo

Thank you Richard and Oscar. I am using AN5 in the rudder post hole. I will ream the .049 bushing. Is there any reason I can't ream it before welding? I can easily ream it in my lathe.

Rudder Post/bar typo

I have a problem with the rudder post (or maybe it's the rudder bar). As per plans, I drilled a hole in the rudder bar to accept a bushing 1" long using 3/8" 18 ga (.049) tube. Plans show a 5/16" inch bolt welded to the rudder post and the rudder bar (bushing) rides on it, so I naturally drilled a h...

Long Fuselage dimension

The long fuse shows 18 7/8" from rear to turtle deck. The short fuse shows 18". If the horizontal stabilizer is 18", why is the long fuse showing 18 7/8"? I'm trying to figure out where to end the turtle deck. Thanks!

Rudder Post

Has anyone welded sections together for the Rudder Post? Bending it seems like a difficult task. Also, regarding the bushing in the rudder bar; plans call for 3/8" 18ga (.049) tube in there with a 5/16" bolt. A 5/16" bolt won't fit in such a tube. So, AN4 bolt with plans specified bushing tube, or A...

Re: Turtle deck boards

Those seven boards that go from the pilot seat-back to just forwards of the tail....I just found in my shop (been several years) I have seven boards labeled Turtle Deck and they are 1" X 1/4". I'll use them.

Thanks!

Re: control sticks connection (rod)

Stops short just before it hits my leg. I'm thinking once the plane is almost complete I can see where the travel is and sand a little from the "V" if I have to.

control sticks connection (rod)

I saw other builders that had to notch out the passenger seat to allow full (left) travel of the control stick. That's due to the rod connecting both sticks hitting the edge of the "V" hole. My aileron horn gets about 5/8" from the floor when I hit the seat. I'm not sure if the aileron travel would ...

Thank you. For the lugs in the forward and aft control sticks where the connector tube attaches, I'm thinking of AN415-2. For the front torque tube collar, it seems I'll need something with a small diameter. I also want to be able to remove and reinstall it while seated in the front cockpit. Checkin...

Torque tube front collar

The plans show a rivet in the forward collar at the front of the torque tube. I'm wondering what other ways have been used to hold the collar in place. While I'm here, has anyone used a cotter pin to keep the tube in place (mounted on control stick lugs) which connects both control sticks? If so, an...

Pilot Headrest/Helmet box

Is the pilot headrest board (typically with a door to the helmet box) attached behind the cross strut? That's how it looks on the plans, but I've seen photos where the builder apparently mounted it on top of the pilot backrest (in front of the cross strut). While I'm here, I can't find dimensions fo...
