Status: online 		Worked on laying down the glass for the tailwheel and gear doors today. Does anyone have a template for the tailwheel door outline? I can try blowing up my line drawing, but I don't have it handy, and it would be tough to get it to the right size on my junky copy machine.

Anyone have this in an email compatible file I can print out? Sure would make cutting out the tail doors easier. They seem to have a pretty unique shape to them. I think I'm going either direct connection or the compression spring loaded wood plate connected to the doors. Looks like Dion's got the connection right though.

Thanks in advance.
Mike

Status: online 		Not going to get too detailed on the doors as the tailwheel hook seems like a little too much work, so I just cut the doors a little longer than was necessary rather than run them all the way back. Got a nice curve to match well with the fuse on the doors, using 4 layers of heavy cloth and Smith systems finishing epoxy, then shaping with a coat of Evercoat. I left the front open for now.

I wanted to have access to the tail wheel mount screws without the doors interfering with my access in any way, so I'll mount a thin piece of plastic over the hole to cover it. Should fair in pretty well and get everything closed up on the bottom.

Now to hinge the doors and put the tailwheel in. I got this really nice retractable tailwheel on ebay for a great price and mount dimensions are same as the 160WC. It has a beefier air cylinder on it and is a bit heavier duty than the Robart one. Problem is the cylinder is TOO LONG . I would either have to make a hole for it in the forward former, or just get the 160 and have it drop in. I can't really get access to the former to make a clean interior cut , so now it looks like the 160WC!! Great another hundred bucks.

Status: online 		For the wing doors, I also decided to use glass, same method. I bought the plane framed up and the cutouts were already made for the gear and wheels, so I have to fill in to shape a little with Evercoat, but it doesn't seem like it will be a problem. I'm using Nelson hinges on all of the doors.

Hi if you are going to put barn doors on I would sugest to make sure that you have a minimum of 1/4 clearence on the sides of the wheels, you can get by with less but it makes it harder to get the open/close system just right..

Status: online 		Bob, I'm thinking about using air cylinders for the doors as the Aerotech wheels I'm planning on using are 4 7/8" which will make things tight. It would also be a little easier to hook them up and get the travel right. I think I remember someone saying that 1/2" travel cylinders will do it. I'll have to see what Bimba or UPC, or Yellow has to offer. I just don't see myself not getting frustrated when setting up the travel and geometry on the spring setup, especially with larger wheels in there.

Status: offline 		Hi guys

Well I finaly got my l/gear doors working slick, even this old dog has learned a coupla of new tricks

I have to say thanks to Dion aka Luke and Dave Bronk, for shareing there ideas and systems with us, they made easy enough even for this frist timer to get it right.

When I started this door project I did not have a plan view of them or any dwg's So I laid out what looked right to me on the T/F plans, so the scale is off and the shapes are a little off but for a fon scale they will do for me.


hear is pic's of the right side..

have to try later server is down

We have another club about 10 miles away, they are big enough that they have a group that just flys war birds, and befor I did my frist build, I ask what was the biggest head ache to the man the ansure was gear doors, there advice was avoid them if you can and use the simpelist system you can.

After looking at several systems air and mechinacal thats why I chose Dion's But the maine thing is to do what you feel comfortable with..

hear are my pic's

Status: online 		Bob, your setup looks great. Nice job on the doors. Not having another air thing to worry about is good and it's the one feature that pulls me to the mechanical linkage.

I got the tailwheel to work, fitting my little Black and Decker remote tool into the fuse with the grinder and then sander to it before I burnt up the spring in it getting a clearance hole in the former in front of the air cylinder. But at least I was able to get the hole big enough on the inside to get a half round file on it before it broke. Now just the hookup.

That set up looks great to me, I have not gotten to that stage as yet so I real don't no what I will do. Are you using plastic fittings in your air lines ??? how did you sequence the doors??, Right now I am trying to decide what I want to do about the under side of the wing at the tip to get it to be alittle more scale like as the out board rib is to deep to get the correct tapper, what ever I do I will try to post pic's, if I think it will help some one..

PS About little tools its to bad we can't find a sorce for retired dental air tools seems to me some of it would be usable. Oh well
