Tail Wheel Brackets
« on: June 13, 2007, 11:43:06 AM »
Mounting a tail wheel on a profile fuselage has always kind of been a nemisis of mine.  I could use some suggestions of a strong uncomplicated way of mounting a tail wheel on fuselage of a profile type plane.

Pictures or methods or both would be great.

Thanks

Mike

Sandwich the upper end of the wire between two pieces of 1/16" ply, with an "L" bend in the wire.  Squeeze smartly with pliers, so the wire dents the ply.  Take the ply. pieces apart and cut, or scrape, a channel for the wire.  Glue the whole mess together, clamping it really well, in a vise or something.  Cut a 1/8" vertical slot in the bottom of the profile fuselage.  Epoxy your assembly in. 

Probably not the accepted way but I don't see any other suggestions.

We use a scrap of motor mount stock with 2 blind nuts glued into a recess cut in the fuselage plank at the rear.  The gear itself is bent with a U at the top that slips under the screws.  It's excessively strong, and allows the gear to be removed, replaced, etc.  It takes longer to try to describe it then to actually make the mount and glue it in.

Simplest way I've foupnd is to bend the tailgear wire. Cut a hardwood dowel to length and groove it for the wire. Be sure to make a groove for the "L-bend" in the wire at the hidden end. Wrap the wire to the dowel with thread coated in Sigment, or your favorite. Drill a hole in the bottom of the fuselage.

Test fit! This is important - - Wanna guess??  Squirt in some Sigment, coat the dowel/wire/thread assembly and insert into the hole. Done.

I do a modification of what Ralph does.  I drill a hole through the center of the dowel, then notch the top for a "j" bend to sit in.  Epoxy it all up after drilling the hole in the fuselage.  Usually a 1/4" dowel about 1"-1 1/2"  long.

Hi Mike,

The dowel method that others have suggested is perfect.

IF you have a drill press, IF you want to buy a bag of ribbed dowels, IF you want to buy 36" MW, IF you like to fiddle with all this, then have fun making one. ;-)

IF you are lazy like me.  Z@@ZZZ   Just contact Eric at RSM and order one already perfectly made for you. And they are less expensive than buying all the pieces. I have used them in several planes. Just drill a hole in your fuselage and install. ... KIS :-)

I got this trick from Larry Cunningham's Building Better Profile articles:

1) bend wire so that the end that goes into the fuse has a 1" 90 degree bend.
2) Press it against the fuse where at 30-45 degree angle.
3) Dremel out a rough channel where the wire made an impression on the fuse. The channel needs to be 1/2 of fuse thickness at that point
4) Glue the wire in with SIG Epoxolite or Brodak Aeropoxy. Make sure to fill the entire channel.
5) Optionally, you can CA 1/64th plywood doublers on each side but like I said, it's optional.

In a pinch, if you don't have Epoxolite or Aeropoxy, use plain epoxy. The only reason to use Epoxolite/Aeropoxy is so save some weight.

By the way, Larry's profile article series is a very good read!
