Title: Again with the waterbug
Post by: D45/70 on March 27, 2017, 02:58:03 PM
You know with out a truck to get out in the field I sure seam to be working on the bug a lot. That is a good thing I suppose . I finished the "slick" paint , the sheet steel and the HDPE runners on. I had it upside down in my shop for over a month. I put her the right side down now and it looks better. I'm planning on taking it over to our Fish wildlife and parks station soon . To have a "VIN" assigned and stamped in the hull. A formality to get a title and registration and a boat number, and permeant tags. I'm going to get it titled as a plane gas powered 12' boat, forgoing some Federal regulations ...
My first plan was not to have bung plugs and just use a high capacity bilge pump. BUT
with the new invasive Mussels the FWP is going to require a permeant drain in a boat hull, in my case two.
EVEN if I never use them they have to be there, humm.
Now I have to do that BEFORE I take her down for said "VIN" number.
I did Redo a small trailer we have to accommodate the 7 1/2 foot wide boat, its a temporary fix till I can make a custom , for my purpose ,trailer just to use to move it around a bit and to water test things as I go.
 I would love to be out practicing killing gophers But, you know life happens .

You are having quite a time of it, D! Now bungholes! Is sure coming along now, going to have it licensed and titled soon and on the water. :)

As for truck shopping, it is really tough to find a good truck and not pay a fortune.

Looks good, D! Have you folks been seeing zebra mussels?
Title: Re: Again with the waterbug
Post by: D45/70 on March 31, 2017, 08:14:46 AM
No adult mussels have been found.
 But there larva have been .
In two of our reservoirs, problem is there "Up stream " impoundments. 
One is in the main stream of the Missouri river and the other is at the head of a  tributary of the Missouri .
 Sounds like bad news to me...

Yeah on bad news, D. Once they get started in a waterway, there is no way to stop them that I know of.

At long last I have the primary clutch "ON" the motor.
I had to relocate the starter an 1/8 inch as to let the front half turn freely.

 Every thing is turning to the left and all the screw on parts are right hand thread. I have roll pins and nut locks an anything in the "Drive train". I'm going to do a power up soon to see if the VW 1600cc will make the clutch engage. The "First" "TEST" ended in a major malfunction. BUT I have added a carrier bearing to prevent that  now, I hope.

 O0 Mechanic porn! Looks good, D! With left hand threaded parts and right hand threaded parts, has the torque caused problems of anything coming loose? Maybe not, since Loktite works very good.
Title: Re: Again with the waterbug
Post by: D45/70 on October 11, 2017, 02:44:22 PM
Could!
I use Loctite on everything and lock nuts, and wire or star lock washers.
 Hope not.

  O0 That ought to work, D. I can expect a full water trial before winter? Your undertaking building the waterbug would be a real learning curve for the rest of us. I think waterbug is a good name for your craft.  O0
Title: Re: Again with the waterbug
Post by: D45/70 on October 12, 2017, 02:10:33 PM
Thanks It has been a challenge.
Today I did a Major test .   A+!!!!!
1971 VW bug 1600cc undetermined  mileage motor.
This set in a shed for maybe 30 years. I Got a new carb at amazon ( still factory settings ),
New coil, plugs wires points and condenser. I set the valves and point with a feeler gauge ,remember them ?a year ago  I had it running on the ground for like 5 minutes for the first test of the clutch adaptor that I had made. It failed in moments. I redesigned and had it fabbed up again, This time with a carrier bearing and a shaft that went in to the piolet bearing in the crank. I Have not ran it since. I built the hull made the motor mounts and finally mounted it on the boat.
Made a mount for the carrier bearing re did the starter to fit.
It is About a year later. Today I needed to start it up and see if my primary clutch off the 1969 Johnson snowmobile would even work.

Dang! I put the fuel line in to a gas can and hit the starter. A dozen turns and she came to life. I have not put a timing light on it yet but it ran very smooth from, 800 rpm (Idle) after the electric choke came all the way off , to 5000 rpm ( as fast as I wanted to turn it unloaded). As stated in the information I could find on the clutch It engaged at 1700rpm and at 3100 rpm was fully moved in for the reduction change. Everything sounded smooth and solid. I ran it for a half hour or so at 2500 rpm. I still have to do some work on my temp and oil psi gauges apparently, but the oil on the dip stick was still cool to the touch.  NICE!

Next to mount the secondary clutch, and see if that part works as expected !!!

Nothing is welded yet I use pop rivets to fab it up.
 They hold together but will not take the strain of running it.
Looks about like what I had envisioned two years ago.

YUP

I did a no load, no prop today.
 All looked good. The clutch started to move at around 1800rpm.
 I did not have my laser tack on the hub but it looked slower then the drive.
 It starts out at 3x1.
 As I increased the motor RPM the clutches both moved, as expected, the clutches
 Topped out at 3000 RPM, right where I was hoping.
 I should be like .70x1 there ,I would guess around the top end for the prop, 3100RPM.
 I didn't run it long but It was quiet and smooth and looked to be running true.

More welding required .
IF IF IF  this year it will be a "Hard Water" test.
As in ice. Only thing open here is the river.
I'm thinking that may be an "Up the creek with out a paddle" thing
:D

Headers on the bug.
With the new little welder I'm plugging along.

I made some headers for the bug motor.

The easiest way was to use the existing pipes and ad

crisscross   Pipes. They point out to the side right now but will

point to the back, I have the mufflers from the "Johnson" jammed on now and they make the bug quite quiet. I'll work with them .



 



 

I did some digging and found out I have my distributor "Plumed" wrong.

When I got the carb I used the vacuum lines that where on the old one, used them by size and they seamed to work.

But on a VW they put vacuum on both sides of the advance diagram

and I had them backwards. AND come to find out In my application , I need to uncap one and leave it to atmosphere and plug it at the carb. Then , this is odd, I have to find TDC of #1 mark the pulley where you time it from mark the Degrees to 28*.

Run the motor up to 3500 rpm and set the mark to 28* Above TDC. I also found out an old fashioned distributor with mechanical weights would be the best in my application.

I'll have to look in to that if I cant get it to 28*.
 
Title: Re: Again with the waterbug
Post by: John Andrews on February 16, 2018, 08:08:33 PM
  :shock:Wow! Not only are you having to be a welder, but a #1 mechanic, too.

Sure is a lot of work but the end result should be great.  O0 Looks like you are almost have it whipped, D.

You must be a very patient man.
Title: Re: Again with the waterbug
Post by: D45/70 on February 17, 2018, 06:25:07 PM
Ok !
 I re plumbed the distributor as directed, and left off and plugged the second Vacuum line.
 I used a  * print out , worked great.
 I found TDS on #1 marked it and took off the prop.
 I fired it up with the timing light on it.
 Ran it up to 3500 rpm and twisted the distributor till I hit
 the stud that was used to hold the old manual fuel pump( I have it capped off ) and use an electric fuel pump.Not quite to the 28* mark with the vacuum line off as needed .
 I was able to cut the stub off some to let the distb. turn farther.
 I set it to 28* clamped it down, and put the vac line back on.
 Put the prop back on and...
PERFICT!!! I now have enough HP to turn the prop up to the required 3100rpm.
 That's all ,but it is right on 3900 rpm on the motor and holds . Nice.
 I have a very short Video of the boat moving , on the snow.
Still lots of work to do like some way to steer , cage ext...

 O0 Nice doesn't even cover it, D! Will you be replacing the electric fuel pump with a mechanical one? The officials issuing the boat title and inspection used to demand mechanical fuel pumps but that was quite a few years ago and may of changed because of modern electronics.

I bought an outboard previously repaired motor that had an electronic car fuel pump installed and had to have it fixed to again have a mechanical fuel pump. The motor was illegal because of the electric fuel pump, a safety issue.

  O0 I sure do like your work!
Title: Re: Again with the waterbug
Post by: D45/70 on February 18, 2018, 02:44:12 PM
 :D
Nope
 No inspection here. The FWP looked out the window at the empty hull and asked whatca going to power it with?
 I said a VW motor and air prop they said cool here is your Vin # and license info.
 Go pay the fee and your title will come in the mail in a week or so. That's It.
OK
 The Elc. Fuel pump stays , It is a low presser High Volume pump in the event I add another carb.

 I'll have three "Hoops" I want to cover the drive unit too as well as the prop.

I'll have a removable screen over the motor also .

I gave 2 1/2 inches for movement and in the event I go with a bigger prop If I hop the bug up.

That gives me 3" to spare to get out of the shop I may not be able to get it under the boat port on a trailer, Dang it.

Ailerons

Un like most small airboats I plan on running "Dry" and on Ice a lot.
I need to be able to adjust the attitude of the boat differently then on water. 
Here is my plan.  "Ailerons".
I'm going to pit 3 small ones before the rudders, to lift the front or back depending what I need.
Remember "work in progress "

I have the structure in for my "Elevators " I found out that's what there called not Ailerons. Anyway , and rudders .
I still need to attach the plates and cut them to fit.

There will be 3 elevators 36" X6" and 2 rudders 50"X 10"

 Going to use ss steel hinges to attach them and use a "Drag link" to hook them together, and move them up and down with a car window motor.

The rudders will be the same but turned with a Mechanical shafts and bell cranks.

I have a lifetime aircraft communications license, D. If you need landing conditions or ramp directives, just holler on your radio, D.  :) It's a residue left over from my old airline days.

I am really looking forward to your first test run and think any bugs will be simple ones. that's a lot of work for a watercraft!  O0
