Very slow build from France


#203

new design parts in sls for 2019
for 57mm tubing
including gap for o-rings
square mount for the gearbox, no more screw
thrust bearing still outside but flush to the propeller…
2 seals for the shaft
keep the same front mast clamping to save money



#204

you know you can not put the screws into the gearbox, from the other side
so what would keep the gearbox that he would not push in


#205

Is that @flying_rodeo prop ?


#206

Yes it is! :hugs::surfing_man:‍♂:blush::muscle::dash::ocean:


#207

nice :wink:
there will be no axial force on the shaft, no push on the gearbox:

  • thrust bearing outside between tubing mount and propeller
  • propeller pin groove is flush to the bottom and deeper than the diameter
  • the propeller is pushing on the thrust bearing not on the pin
  • the propeller is “loose” from the shaft
  • bolt on the shaft after the propeller

so 1mm play forward and backward for the gearbox, and a bolt on a rear prop so it won’t came off the pin when slowing down


#208

@flying_rodeo, a piece of art, really !

@Alexandre, is the copper piece between the chief and the chief shaft screwed to the Reisenauer ? What is it for please ?


#209

2 of these :

Screwed and glued on the shaft , one for the seals one to center the thrust bearing

Just to smooth the shaft to 12mm and to keep the end with m10x100


#210

new board, thanks to @Gobbla
water line included in the mast
fitting new part and tubing 57*60
waiting to choose the motor to cut the tube


#211

I like the new board! Are you planning on making an electronic compartment inside the board?


#212

yes i would like to, but it is not deep enough for most waterproof case (100mm)

so i might add 30mm to the board or build a custom waterproof case, i just need 80mm for the 18650 and the board will be ok

i want something flat on top …

as a new board, it is a rrd k race 2012-2013 carbone pvc, beautiful , i don’t want to cut it …


#213

I feel you haha. I also have a brand new race board (cabrinha VMG carbon). I am planning on inserting a ride engine track box to mount the foil, and create a built-in waterproof compartment for my battery pack and electronics so that everything fits inside the board. If you want to brainstorm idea on how to proceed and make everything water tight, send me a pm. Je parle Francais aussi!!


#214

thank you…

my plan is to use or build a waterproof case, no compartement “waterproof” in the board

it got use to put the case on top (on the old board), i find it more convient this way, i just want it inside the new board


#215

Why not build a compartment then? I also thought of making a custom box at first so I am curious to know why you would prefer a custom box to a custom compartment!


#216

easier to carry just the board and just the case, the board can be “left” in the car, i use the case to carry and protect the battery, easier to work on electrical parts at home without the board, stronger to put my feet on it…


#217

Good points! I might make a battery case but not necessarily waterproof as it will be in the waterproof compartment. How are you planning on fixing the foil to the board?


#218

right now the idea is to make a square frame in wood and fiber (size of the case and the mast) , cut the board, put the frame and more fiber (top and bottom)
not to sure yet… on the first board i just drill 4 hole and put 2mm metal plate on top and bottom, ugly but worked very well


#219

Were you planning on glassing the hole for the square frame before glassing it into the board?


#220

no i was planning to use hard liquid polyuretane foam


#221

To prevent the wood from digging in the foam with time?


#222

yes and to prevent water in the board… not to sure about my glassing skill :wink:
