Hello all
I was rather chuffed that to date the propshaft and bushes all seem to be fitting well in the 'putting all in situ' stage. I brought the motor to the boat and ooops the shaft from the motor is about 1/2" higher than that of the propshaft; the motor just placed on the keel spar. Drat or words to that effect.
The motor I had thought of using, in the cargo ship Hunan, is a Bühler (possibly a 3030) 6-18v type 80mm or so long and 55 mm in diameter with a 6mm shaft of about 60mm protruding.
The motor Is Quiet and ought to have good torque.
I am not particularly wanting to chisel out a section of the keel spar and so I have to consider either a different motor or find a mechanism and toothed pulleys to apply to the Bühler in order to achieve a lower drive shaft position to marry- up with the propshaft.x
I have a torpedo 500 geared motor with 6:1 reduction and which runs from 4.5-15v.
I am just not sure if this motor would be happy or if out would be constantly working at the top end.
The size difference between the Bühler and the torpedo 500 is clear. Perhaps that is what is making me think that the torpedo will be under- powered/ over- worked. The gearbox may prevent that and you all may say that it is ok.
The ship is 6'6" in length and about 14" in the beam and weighs currently approximately 13kgs or just under 29lbs. This is without batteries or ballasting. Bryan in previous correspondence to me estimated that the vessel would need a displacement of approx 80lbs..
The question is,: is the geared torpedo going to be suitable or can one buy a system for operating via belt drive between motor and shaft at a 1:1 ratio as though direct drive.
I have a couple of belt drive motors but they are in another vessel. I bought them second- hand and so do not know who stocks this type of motor but obviously they were available.
Anyone any ideas?
