Have I gone too far in the Wrong direction with this mount ?

[philmountains]

Hi all I have trolled through the site ,and found quite a few mounting ideas especially some of your senior posters "z" ,which looks absolutely fantastic workmanship ,However I have produced the mount which you can see in the following pictures ,the guys from back shed.com have been great in helping to Identify I have a problem, re -tail boom and Furling which I want to incorporate but at the time I was welding this up just did not think enough about!!!! the only thing which has put me off scrapping this mount is I do not trust the welds that are on the motor, for a side mount like the name which the checker will not let me put in ? "Z",and I do not want to strip the motor down to reinforce the welds as I am not wanting to rewire it, or indeed have the expertise, or time as the whole project is done when I have a bit of spare time at work !!!

Thanks for any help Phil

Phil,

DEPENDS?

That mount looks ideal for a tiltup whereby you allow to rotate the entire motor/rotor assembly in a vertical orientation with a furl stop at 45 degrees (or whatever).

A forward stop keeps it from getting too close to the tower ( ie 5 degrees?)

It those designs, the tail is attached rigidly to swiveling assembly you have already.

Weight of tail becomes irrelevant

The off-balance force is easy to calculate as in this thread:

simply:

P= 0.0026 X (Area) X (wind velocity ^2)

a small pair of springs keeps it from popping up and a digital postal scale can determine the offset weight you need.

This is exactly what I am currently designing for an 18 footer with a furl at 20mph

weld a new mounting plate over overhang on the existing metal in a size that will allow 5 or 6" offset from tower head and forward enough for blade clearance, now you can add a tail hinge, pepa.
