Title: Drive set up for Lucy Ashton
Post by: waverleyjamesieboy on July 29, 2016, 08:12:26 AM

Hi paddleducks, not been on for a long time due to other commitments. But I have managed to get back to model boats  :). Recently I acquired a model of the Lucy Ashton, I am giving it a thorough renovation. My Waverley is on hold at the moment while I rebuild this model (not that I have had much chance to work on it for a while  :(). Now to get towards the point  ;D there was not much of the electrics left in it. What was in it was a small motor which didn't work any longer, attached to it a small planetary style gearbox. On the end of the box was a small cog, driving a larger one attached to the paddle shaft via a chain. There was nothing on the motor so no idea what size it was, but was the smallest motor I've seen. What I would like to know (at last everyone says lol  :D), I have got a MFA torpedo motor 500. Can anyone help as to how to use this to power the model, for tech details all I can say at moment it is appox 4' long by 14" wide. Sorry for long post but hope someone can help.

Could you post photos it may help someone understand your problem better. A picture is worth a thousand words.

I use photopad by NCH software for photo processing. Size / rotation / enhancement etc.

my rule of thumb is 300/350 rpm at the paddle shaft , i dont allow anything for slip+we have a speed control to slow it down
typically 540 type motors+2, 1 per wheel +3:1 ratio reduction tooth belts  ratio to get shaft rpm right.
 this set up drives 4/4.5 ft loa paddlers well, latest used 1000 rpm planetary motors via 3:1 t belts to a set of adelaide p wheels, but wider than the adelaide used , UK paddle tug

I built Lucy Ashton originally and the motor was one coupled to a reduction gearbox - a type no longer available.  With feathering paddles one does not need high paddle speeds or all you get is slip.  My first model Lincoln Castle we used a Meccano motor with adjustable gearbox and found that around 150rpm maximum was best, but that motor when I converted to electronic speed control and digital R/c  (my original set was an old reed one) caused too much interference so I had to look elsewhere.
