Title: A day in the shop with the waterbug
Post by: D45/70 on February 26, 2017, 10:33:53 AM
 


I flipped the Waterbug hull bottom side up to work on the hulls.
I added some more bridging and cross support.

Then I took some 20 gauge cold roll and bent it to shape and added a small trim tab to the bottom and back of the hulls.
 The cold roll is to help stop sharp ice/rocks and it slides better then Aluminum. The lip is to "Brake" the water like a drip edge on your roof.

I'll add three ,four inch by 1/2 inch hdpe plastic to each cat to make it slide even better .

I'll paint the aluminum with a rubberized paint before permanently attaching the sheet. Then I plan to coat the cold roll with "Gaiter Glide" before the plastic to make it slid as easy as I can.
One day I'll put a motor on this thing...D

That should really slide over ice and water, D! You are going to use something like an airboat fan motor? Or one of those jet setups like they use on the Colorado River?

:) When you crank that up, it will be one of hell on wheels go anywhere boats, D!

Your boat has been quite an undertaking. What's next with its build?

:idiot2 YUP For sure.


 After I get the Hdpe On I'll paint the bottoms with Gaiter glide Paint to make it very slick. Then Back over and start putting the motor on. Have to fab up every thing. Did you know a VW motor does not use motor mounts? It must hang off the transaxle. I'm thinking about some kind of "L" brackets on the back where the bell housing would mount and under the block letting it kinda resting on rubber pads .
ALL the rest of the stuff like the drive ,prop, and the prop cage Has to attach to the motor mounting system so if there is any movement it is all together and move as one.

Still a ton of designing to do Rudders, Ailerons, Helm, electronics , ext

No, I sure didn't know that about VW motors. You still have a lot of work, for sure. You won't have to worry about shallows and mudflats when you get it finished.

I reckon you didn't expect that much work, I wouldn't have. You should have it out for a trial this Spring?

In fact I think the work involved is about what I thought it would be.
 The $$$ on the other hand...
When I got the motor for a $100 T thought wow what a cheep way to get an airboat, WRONG!
Course I already have a boat and knew that ANYTHING for "Boat" is big $$$ :tickedoff

Spring time test may be a stretch.

Yeah, I bet it was VERY expensive but much cheaper than hiring it built! Your build looks like nothing like anything I have ever seen, and I have seen a lot of boats. I live close to the Mississippi River. We have a lot of jon boat and other builders around here.

In Texas, I lived 200 yards from the waters of the Gulf. Your design would be very welcome there and here. your boat looks a lot more stable than regular airboats.

I think your boat will be able to haul a pretty hefty load, will not be just a wave jumper. It looks like a cross between a pontoon and johnboat. I like it very much.

You have a lot of design skill and very well appreciated here. :) I bet the kids are more than ready for a ride.

I'm an a mini airboat board, there not seeing my vision .
Most think I have horns growing out of my head in fact.
All I can say is " we will see"
I hope it works 1/2 as well as I think at least.
I'm expecting a different prop to be delivered this week , The one I have turns the wrong way , dang it. There both used but an expensive mistake for sure.

MAn did you ever score on the VW motor. Back in the day, you could buy them all over at that price and fully rebuilt for $300 and pretty heavily modified for 5-600. I would still love to have a pipe frame buggy and recently checked flea-bay prices.  :shock: The stock motor (possibly needs rebuilt) is a cool Grand or more !!
 Screw the buggy idea. Just a side note some Porshe motors bolt right up to a VW transaxle, so my be an alternative if you ever need a new motor.

Well I got all the metals prepped for paint.
Painted the underside of the sheet and the Aluminum part under the sheet with rubber  truck undercoating.
Then I painted 3 layers of Gaiter glide, slick paint .
Next is the HDPE.

It looks to me like you have had a lot of experience welding and fabricating, D. You have undertaken a lot of work I could not do. Your boat looks like a real professional job.

When I looked up the online information of your space age slick boat paint, I was amazed. Here on a busy river, we have never heard of the stuff.

Well thanks but...
 I have never welded in my life and still can't/don't. I have to Pay much $$$ to get it done.
I have been "Red necking" Frankenstein " projects in the back yard all my life.
 Started with wooden produce box go karts and bicycles.
 This is my biggest and $$$ to date, I hope it works , my wife will kill me if it does not.!!!

D,most great inventors have gone the same route! I really like your design and boat very much. It's going to be a winner.

I have never welded but have done a lot of soldering. Two of my sons are welders.

How did you come up with the idea of using that slick paint? Like I said, I never heard of it before but it looks like the perfect paint for a boat bottom.

  the boy got a recommendation for the paint from , "Mud Devil"
He was talking with them about a different mud prop for his Mud boat and they suggested it.
 There are other brands but all about the same but there all very $$$.
 We did some research and this brand sounded the best of the best, so far it seams like every thing they claim.
