DA50 Spinner Bolt Thread Size??
 

Does anyone know the type/size bolt for attaching a spinner to the DA50s prop shaft?

Thanks,

should be in the instructions, probably a 10-32..[8D]

Not that I could find, that's why I asked. ;-)

It is 10-32. Not that I read that anywhere, but I purchased a TruTurn spinner that claims to come with a 10-32 bolt... and it fit the DA-50 perfectly! I was worried that I would need some crazy adapter but it seems just fine as-is.

It is 5mm

Thanks guys:

Guess I'll have to check with DA to clear up the confusion. ;-)

Here is my email to DA and Daves response.


What bolt size, 10/32 or 5MM, are the prop bolts and
the spinner bolt on a DA50-R.

Hello
They are 5mm but 10/32 works fine for the spinner cone.
Stick with 5mm for the prop bolts.
Thanks
Dave

I have bolts for the prop, just need one for the spinner.

Thanks,

Finding out a 3/16 bolt will fit where you really need a 5mm is one of the things that really makes life wonderful.

It will work for the spinner bolt, but a 10-32 is about .006 smaller and will strip out if you use one in a place designed for a 5mm, like the prop bolts...
I gotta ask Dave why an engine made in Arizona, USA, uses metric bolts...:D
Yes, some of the parts are made elsewhere..The crankcases are made from 7075 aluminum in Tucson, AZ...To the best of my knowledge the ONLY model airplane engine cases made on a CNC machine from 7075, the best and most expensive aluminum alloy, not from CHEAP POROUS castings like some other engines...
NO, not all engine cases are CHEAP and POROUS...:D

Why not? The rest of the world (ie market) uses metric sizes.

I'm 69 years old, been a machinist and using inches all my life, this is the USA, the rest of the world can KM:D

Well, they say you can't teach an old dog new tricks, but I guess those that realize the new tricks lead to more reward are happier.;)

I prefer to divide by ten rather than figure out how many pecks are in a gross of bushels. Or how many ounces in a hogshead!:)

I'll take DA quality with the metric...or without![sm=thumbup.gif]
