tightening of a wooden prop

Postby karoopilot » Tue Oct 16, 2012 7:24 pm

Good question I'd also like to know and is this just for wooden props?

Why not ask the king himself?

Pieter de Necker published a book in 1995 named "The Handling, Care and Maintenance of Wood Propellers". It is a very comprehensive piece of work and should be in the hands of all users of such propelling devices vhpy I hope for your sake, and anybody flying a wood propeller, that it is still available.

Google him and get one. (^^)

Bel Oom Pieter hy gee 'n boekie/handleiding saam met se props wat jou presies vertel hoe om die tracking te doen en na jou prop te kyk.

Sodra ek n ligte vibrasie voel dan weet ek dit is tyd om die prop te torque.Partymaal min ure 10 tot vyftien?

Ek het baie oulike boek van oom Piet gekry. Ek is seker indien jy n P Prop op jou vliegmasjien het, sal hy jou daarmee kan help, of, stuur jou prop in vir n service puff en dan kry jy sy boekie saam verniet by!!!! vhpy

Nico,

Jammer kom nou eers terug. Internet was vir 4 dae af agv hierdie nuwe internet "upgrade" van Vodacom. :evil:

Man, ek het alles op PDF file, maar daar is "Copyrights" :( en oom Piet gaan nie gelukkig wees indien ons dit op die web plaas. Die boekie is regtig n moet hê vir alle tipes skroewe.

Dalk moet ons hom vra of hy sal omgee indien ons dit kan plaas.

Lekker gereën hierdie naweek, en dit beteken ons kan dan nie vlieg :(> , maar is meer dankbaar daarvoor, nou is dit plant tyd!!!!!!!!!!!!!!

To get the "slack" out of the threads, start off with 3 to 5N/M. :? Do your tracking. The final setting is 13N/M. xxx
18 is very high!!! By then you should have indented the plate into the wood, not GOOD!! :(

Hope it helps.
