Since my last post on this subject Ive been waiting for my funding to accumulate and the post to arrive but as of Saturday the waiting was over and so over the last days Ive been getting some building done. Well a lot actually!
First up i received my new motor ESC and gear for the impeller. I ordered from giant cod a cheap and cheerful 2200kv brushless outrunner with a none marked 80a forward only esc. I made a brand new impeller using the gear as a boss for the centre, reversed the shaft on the motor so it came out threw the base and mounted it to a piece of plasticard.
I did a spin test with a 3s lipo and the impeller didnt explode so its all good (touch wood)
I then started working on the pump casing. I marked out the shape of the casing on cardboard drew and cut it out on several peices of ply and plasticard andf then laminated them togeather to build up the height.
For some reason i didnt take a picture of the completed pump on its own, it will show up in these later pics. Anyway i started planning out the hull. Im not sure yet what type of boat im going to build and have no idea how well it will perform so i built a small but basic hull and HOPEFULLY the jet will provide some ample shove for it.
I then started cutting out the transom and fitted to the pump. In this picture you can see the inside of the pump housing itself with the impeller off.
a peice of tube is fixed into the end of the pump jet, i smoothed off the square to cirlce profile with epoxy putty to improve the flow.
A bit of a frame just to get my started:
After this im afraid there was a gargantuan leap of progress and i was so busy i forgot to take pictures
The Hull is made from entire peices, 2 chines and 2 bottoms:
The blocks running up the inside of the chines reinforces the seam with the bottom and the **** at the front just holds it togeather while its drying. The interior is not pretty but once the deck is on it wont be seen. A few more gaps need filling but ive pretty much got this part out of the way. Heres a pic of the pump casing closer up:
another update coming soon
