Default Composite tail wheel bracket

Has anyone ever built a carbon fiber, composite, tail wheel bracket?


I have seen some for sale, but me being cheap would like to make my own.


Would it be possible to cut a block of wood with the curvature you need for the bracket, and then sand the cut smooth on both pieces and use the two as a mold and squeeze the laminate togethor?

Any suggestions on number of layers and fabric weight?

Also would you combine different fabrics for any benifits?

Like Carbon, kevlar, and glass or would it be stronger with just carbon?

I know it all has probably been asked before, but I couldnt find anything.

Default RE: Composite tail wheel bracket

I have done this, and it works well.
Your method of pressing the item between two wooden mold halves should be OK, but Blue or pink foam also work reasonably for this, and is easier to work with. I cut mine from a 2" block on a band saw. Line the mold halves with some release film, polythene bag material or whatever you may have, and off you go. Can't go much wrong with a tail bracket.!!
I live in "the other part of the world" where everything is metric, and I have found that carbon cloth builds approx. 1mm per 800 gram cloth, i.e. 4 layers of 200 g/m2 cloth builds 1 mm. 1-1.5 mm thickness should be OK for this, my brackets for 2M pattern models are slightly more than 1mm thick. If it turns out a bit thicker/stiffer than anticipated, then just cut it narrower. It really all depends how stiff/strong/heavy you want it, and what model size you are talking.
(In your money, aim for a thickness of between 1/32" and 3/64", 4-6 layers of 6 oz/yd cloth.)
