Don't wake a Tiger until you've factored the teeth




After the very average first boat build (http://www.rcindia.org/boats/first-boat-build-24'-cabin-cruiser/) I was itching to try something more challenging.

So, I pestered VC, and he suggested I download the plans for the Keil Kraft Neptune and scale them up.

This is what it is supposed to look like ( :ouch!  Shocked)

I downloaded the plans (http://eezebilt.hobby-site.com/index.html) and took them to a photocopy shop. The scaling was not perfect; instead of 150% got about 140% and the X & Y axes scaling was a little different  Head Scratching Head Scratching

All the templates cut on the Sunboard. Used 2 mm wherever the plans said 1/32 or 1/16" and 4 mm wherever they said 3/32 or 1/8".

Build in progress. Used Cyano. This material (a first for me) is quite easy to cut and sand; a MAS plane is very useful. Only thing it is heavy, and a little brittle. But overall, very nice to work with.

Don't wake a Tiger until you've factored the teeth



I had to make a prop shaft tube (sometimes called a stuffing box, although I disagree - a stuffing box involves compression of a media to form a steam leakproof seal, e.g. in steam engines  Cool )

I had some Aluminum tube lying around, 7 mm X 9 mm. I found an old commode nylon screw, which too was 7 mm O/D. So I created it. I used 2 pieces about 7 mm dia X 12 long, and drilled a 3 mm hole for the shaft (a bicycle spoke.) Used a set screw to lock the nylon into place, and will keep a bit of sponge soaked in thick lube oil inside  Grin

Don't wake a Tiger until you've factored the teeth



Build continues. All easy so far. The only thing is that despite cutting the templates carefully many things don't fit. I guess it's because of the photocopying, or maybe the plans had a few small errors. Errors IMHO don't ever cancel out, but add up  Grin

The only part which needs minuscule fitting is the very last - the 2 bottom skins. The rest are all easy.

The motor has yet to be decided  Huh? Huh?

I think a brushed of about 150 W (about 17 A) with about 2000 KV or higher should be OK, this boat is heavy! I do need advice on this though, which will be much appreciated.

I put a lot of hot glue from inside on the joints, hoping to seal the bulkheads and make it as unsinkable as the Titanic  ROFL



(....to be contd.)

Thanks Aniket! The only spectacular thing a boat does is......sink  ROFL

It will take me a week or so to complete. I will be posting more build pics, and, hopefully a video of the maiden voyage  Grin

I've witnessed that workbench in person. It's a builders dream. There is nothing that one cannot find in that workshop except for the light switch, which is hidden at a place only Rai sir can find in the dark Wink, so no one eyes-on without his consent Cheesy

Great build sir...

Hi - I note that you are making some of the KK EeZeBilt boats from my website.

The idea behind the website was to revive some of the old boats that people in the 1960s were used to, so I'm glad that this is happening, but I'm sad to hear that on occasions you find that there may be errors with the drawings.

The drawings never existed originally - these boat kits were simply provided as a set of die-cut parts. I produced the drawings by getting collectors around the world to photocopy the die-cut parts. They then emailed them to me and I drew the plans from these pictures. Sometimes it was hard to see where the lines were, so it is quite possible that I got some wrong. I would appreciate a bit more information about just what is wrong, so that I can correct it...

Oh, and congratulations on the building - those boats look very good...
