I got the elevator actuator hooked up and it moves them up and down, Yay . A tad slower then I planed but workable.
I used a car window motor.

Go buy some acme thread to replace the all thread and that will get much faster and last a lot longer also.

I found a trailer , needs some work !
It is 7 and 1/2 foot wide
12 feet long, the deck.
AND needs some work.
I got it for free, it has tires and a title.
It will be a push/pull trailer, tongue on both ends the telescope in when not used.
I need to be able to drive "on" and drive "off"

It needed tires:
OK, here is what I got.
RubberMaster 20.5x8 10 range F. There made in Indonesia.

Rim Width (Inches): 6.0
Outside Diameter (Inches): 20.60
Section Width (Inches): 8.10
Max Load: 1549 lbs.
PSI: 90

Two tires and two white rims 5 hole.

My buddy the tire guy balanced them and will

mount one of the old ones on one of the old rims, for a spare.

$135.00

I had to replace a stud , 7/16 - 20 and I got some extra nuts, $8.00

I checked the bearings and they looked and felt ok, I repacked them with grease that may actually flow in cold weather. I'll change them and add Barring buddy soon as I can. Never enough money or time ...

Galvanized rims would be the best, but for now I'll just paint the white ones Camo ad call it good.

Now just re do the entire trailer for cat, boat and it will be finished.

I needed some U joints for the steering on the waterbug.

There like $30 each on the computer, I need three.

They turn slow and only one revolution so I did not need precision just flex to change sides of the boat with My tubing. They fit over the 1" tubing I'm using.

Handle bars will turn a drum with cables to the tubing shaft.

The shaft will run the length of the boat to the back.

Then a drum back there too with cables to the steering arms on the rudders .

Closer by the day... :Drink:

There not on a spinning shaft.
I needed to change the direction slightly on my steering set up.
They will make one revolution at max to max.
And turn very slowly.
There made out of 1" steel tubing.
All I can do is hope I guess. :Noteeth:

Well
At long last I have steering for the waterbug.
Still needs adjusting and cable tightening.
I'll get some pics and maybe a Video up this week.

Working on the accelerator. On a VW motor single carburetor the butterfly leavers need about 3" of movement.
I'm trying to use the thumb leaver off the snowmobile or maybe the brake lever but they only give me about an inch
of movement. I have tried serval "Bell crank" set ups with out any luck.
Finally, I think I'm on the right track. It's a leaver and pully set up to Pull from the back of the butterfly linkage.
If I use the long part of the leaver to actuate the butterfly and WAY down near the bottom for the thumb leaver cable.
I Think I will need to use the hand brake leaver to get enough leverage to open it with only one hand.
Now I have to think of a way to mount the cable to the motor somehow/ somewhere .
It's been a few weeks of trial and error . I need to get past this and start the trailer. :Drink:
