RE: CMP Hellcat
Great idea Hal! Now how about some pictures!
Preto, I would help but I'm not sure about what it is you are asking, sorry!
Now for the regularly scheduled program!
In order to build this tail wheel as close to straight as possible you are going to have to assemble some basic jigs. We shall start with the wheel yoke in assembling our parts. Notice in the first picture that I cut a slab of balsa to the proper width to allow the fork pieces to rest on the bottom of the top square piece. For the axle I’m using 3/32” brass tube, the inner axle that I’ll show you later is 1/8” brass tube. Anyway, drill a hole all the way through so that you can insert the brass axle. Use some pins to help secure the pieces further.
Next find the center of the top piece so that you can drill a hole for your steering rod. I’m going to use the 3/32” brass tube for a steering rod, I used 1/8” on my other one but I think it was overkill. Use whatever you think your tail wheel will need. I’m trying to save weight also wherever I can.
Solder your steering rod to the centerpiece.
Cut the steering rod to a length of 1 5/8”.
Use some medium CA to glue the steering rod piece to the top of the jig. Just use a small amount of glue on the end of the steering rod, try not to get it all over.
Now a soldering trick, lay down two small drops of solder on both the fork and the top piece.
Now when you lay the small brass angle piece on the solder and touch it with your soldering iron the solder will melt and pull the piece to the parts. Then hit the outer surface with some solder.
