threaded ferrul
« on: February 09, 2007, 12:54:23 PM »

hi guys i have a question for you i have a ferrule here thats threaded at the stub shaft side ,should i get a threaded shaft to fit ? or drill out the threads to accept an unthreaded shaft?.then i will need to drill and tap the ferrule for grub screws also.the other problem is i havent seen any threaded 1/4 shafts anywhere most are m5 threads .thanks !!.

Guess this is the one you got from Jamie  ;) I would keep the threads and find a shaft to fit or make one. Could be from Top Secret http://topsecretboats.com/inc/sdetail/205 or Warehouse Hobbies http://www.easycart.net/whobbies/Drive_Components.html
To me it would be a backward move to drill out and then use grub screws. See if Blue Fishy http://www.bluefishy78.com./ has them or ask Dave Marles for just a blank.

I know that the fast electric boys use loctite to hold the threaded prop end on the shaft, and they develop quite a lot of thrust.
