Oki doke!


Ball is rolling now, en route is my motor, batterys, Action Electronics have also sorted me out a modified P103 for my 24v setup which will be 4x 12v 20Ah batteries linked in Parallel/series combo to give me 24v 40Ah (gareth) was the chap i spoke to, very good chap indeed and knows his stuff (unlike me!). I was also going to buy the P98 ESC from them but they out of stock at mo :-( so will have to wait. Ive also splashed out on 1 of those soldering iron helping hands things as ive got a feeling im going to need it!


Going to pick up some materials for the build this week in terms of wood/fillers and glues etc, clock is ticking, about 3 more weeks for my hull to be ready!!


Will also order the prop this week which is from Prop-Shop but going to wait to order the shaft until hull arrives as i will need to measure the length i need.


Anyway im.really excited about this build, cant wait lol :-)

If you know what the thread size of the prop then Ill measure my shaft for you and then if you contact Steve form Model boat bits he will make you one exactly the same as mine....Sorry to say this but you WILL NOT Buy a better shaft ANYWHERE

Hiya mate, well my motor shaft is 8mm so im going to try keep it all at 8mm to keep it simple, i was going to get the shaft from MMM along with the coupling etc, the prop will have an 8mm thread but i need to ring prop shop to make sure they can do 8mm :-)

If this is the motor you are to use [with the 8mm output shaft] you are off to a very good start

The image shows a very robust mount frame which is secured to both ends of the motor

Take a leaf from full size installation and consider construction of a mating frame assembly with the same footprint to be epoxied into the hull, however with four M? studs securely fixed to the frame......with nuts and lock nuts you will have a motor fame that can be accurately adjusted for true alignment with the angle of the prop shaft, but also adjustment for true alignment with the axis of the prop shaft

Using an 8mm shaft may infact require two shorter sub tube assemblies [for adequate support], as opposed to one continuous outer tube

I suspect the 8mm diameter shaft will require an outer tube of say 14mm :o

Keep us posted as this drive will be of interest to many  O0

Hiya Derek :)


Indeed that is the one!


Im going to be ordering the prop shaft from MMM probably as they sell one which has 8mm shaft & 12.5mm tube: http://www.mobilemarinemodels.com/maxline-2422-p.asp they also do custom size couplings :)


No probs about keeping you updated i will be posting my progress regulary on this topic :)

First couple of bits arrived, 2 of the 4 batteries, they only had 2 in stock! :( & motor, i gave the motor a quick test, working fine & very quiet, but i'm going to need to get a sprocket removal tool prob as its on solid!

Heres wiring diagram that A.Electronics sent me for wiring up my batts to the modified P103 they have done for me which in total will give me 40Ah & 24 Volt..

Hi,
  That splined end looks exactly like the one that was on my motor and if it is the same its quite soft metal, I removed mine by carefully hack sawing both sides the splitting the metal (slowly and with care). Hope this helps.
    Cheers,
          Pete.

I have removed them by carefully
cutting along the groove in the splines
with a cutting disc in a dremel.

hey guys :)


i was thinking of using my dremmel but wasnt too sure, but if its a soft metal will give it a shot & cut inbetween splines as mentioned, cheers guys :)


On another note, i have just recieved the mount from MMM... fine piece of kit i must say, looks solid & very well built. But my motor is way too small for it & the mount is for the BF24 that MMM sell.


So I think im going to buy the BF24 motor from MMM, its quite pricey but it will be a solid & secure & its also 12 poles so im guessing will have much more torque than this motor I have which is 150watt.


I will keep the 150watt motor & use it on a smaller build in the future :)


Anyway here some pics of the mount & then a pic of mount with my motor which you can see it falls way short for the mount.

Daz....

Electric motor [pairs] of poles is a design function which dictates speed......you can think of torque is a by product of speed...[but at the expense of current draw]

Clearly the motor mount has been incorrectly ordered or incorrectly supplied........could you not return it for a replacement of the same sizing as you previously displayed which suits the ZY 6812 [24 volt - 150W motor] ?

Hi Derek :)


The Motor & Mount are from 2 seperate places, when i bought the mount i did so knowing that i may need to modify it for the motor i already have to fit, however the advert for the motor i have bought stated that the barrel was 135mm in length, however i have just measured it & its actually 105mm... 32mm shorter than advertised! If i knew it was only 105mm i would not have bought it as i knew the mount i was going to get was for a motor with a barrel length of 155mm. So i've sent them an email to the motor supplier, not that its going to make any difference unless they have sent me the wrong motor by mistake.


But i have a couple of options..


I could get a mount made to fit this motor or i could buy the motor from MMM which will fit prefectly in the mount i bought from them & put this motor to the side for another build in future.


Marks Model Bits offer bespoke engineering service so im going to drop them a message about fixing a mount up for this motor, i know the mount is a simple piece of kit but i dont have the right tools or i would make my own :(


The only thing im worrying about at the moment is if this motor will have enough power to drive my tug which will have a 15cm diamater prop, the motor is 24 volt & ive tested it on the bench at seems to have plenty of torque etc but i dont have any tool for measuring its power etc so the proof will be "in the pudding" as they say once i get the hull & give it an actual test :)

As you are going down to collect your hull...WHY NOT ASK the man himself what motor and prop you should be using ...






Dave


ps...make sure your car is big enough...as boy oh boy did I get some funny looks off a copper as the Tid was uspide down on my head....OH by the way the car was a Corsa and was allready full of boats etc having been to Wickstead

Hiya,


Ive already asked he just said a big one lol :-( but ive got this one here im going to try so will see how it is, my car a c4 grand picasso (7seater) ive measured the space with all rear seats down and it will fit in, its the first thing i checked before i ordered it lol :-)


Prop wise is what i originally thought, 6" (15cm) 4 blade, prop-shop also confirmed that this should be ideal, so as soon i get the hull and measure it to make sure the prop will fit, i will then place the order for it :-)

Well, picked up my hull yesterday, after a long (but enjoyable drive of around 10 hour round trip) I have to say, the Hull is a piece of art, very nice craftsmanship.. i don't know too much about fibreglass hulls but I know enough to say Andy has done an excellent job & hes also a very nice chap!


Few pics below, to give a small reference to the size, ive placed a can of pop next to it in a couple of the pictures!











As ive mentioned earlier, im building the tug based on the Anteo so i'm probably going to be making my own superstructure out of ply, or i will modify the fibreglass one that came with the hull, but will see :)


Let the FUN begin!! : :D :D  :D

haha! :D


i was waiting to see if anyone noticed (honest!!) :D


couple of more pics & also another goody arrived in post in form of a P103 board from Action, this is a modified version of the P103 as it will be running 24v on 4x 12v gel cells that i'm going to be running in series/parallel setup.

Hiya, sure it was from Ebay but i'm still yet to test it, its a 24v 150watt, 3500rpm, its basically a scooter motor, so if it can shift a person around on a scooter at around 10mph then it should be fine pushing the tug along, time will tell i've almost finished making a mount for it, MMM also do a 24volt motor which (if this one i already have ain't upto the task) i will probably buy the one from MMM :)

Bonjour Tizdaz,
No problem with your choice, you do not need a lot of power to push or pull even a large boat, my tug Jan has just a Stuart D10 and see what it can do with less than 2 bars od steam pressure (the launch weighs about 450 kilos!) : https://www.youtube.com/watch?v=BPPux5exRNE
Idemwith my Moulay-Idris : https://www.youtube.com/watch?v=_8BZAgnvt6E  :-))

Bonjour Tizdaz,
I have to confess that I know by experience how an electric engine is quite more powerful than an elsewhere powerful steam boat.

Have a glance to this video and see how a simple Power 1000 pulls my 20 cm3 Reeves Warrior MK3 tug Moulay-Idris :  https://www.youtube.com/watch?v=HF0bGRDXGjA
