Title: Waterbug one more step
Post by: D45/70 on April 23, 2017, 05:02:59 PM
I figured I would at least set the bug motor on the cat hulls. My buddy is ill and we could not get started actually mounting it.

Oh, man! One more step! Is too bad your buddy is sick. Is he going to get well soon?

Can't wait to see what you got dreamed up to mount the motor.

The motor looks huge sitting there!

A VW motor has no motor mounts...
It normally mounts to the transaxle and that's it.
 I think I'll make some heavy "L" brackets that mount to the back then go forward and put two rubber "Pads" to pull some of the weight off the Magnesium case.
they will span three of my cross tubes and mount in the center of each cat.
 As to not "Spread" the cats outwards .

It does look big but it's the cooling tin that is FLAT giving it that "BIG" look.
 It is well under 300 pounds

I'm wouldn't worry much about pulling weight/stress off the case. VW didn't and all them guys using them on pipe frame buggies don't. Them things get abused alot more than bouncing along on a river, however getting sufficient bracing in the mounting angles may prove to be the biggest engineering feat of the whole project. I know it has been done many times, but I never paid attention to how. I think they may mount to a plate built into the prop cage, which in itself presents a significant footprint. Certainly should be enough to support the motor assuming the deck between the cats where it mounts is strong/thick enough.
 Why am I babbleing on ?? I'm sure you are way ahead of me on this.

Please babble on .
 I review every suggestion I get.
 I'm not an engineer designer, or boat builder.
 I'm barely a back yard Fabricator.
 I do ,do a lot of research, reading, and a big fan of U tube for self help stuff.
 Any of my ideas and plans can be changed , hopefully to the better.
Thanks
D

The VW motor is officially attached to the Hull !!!!
I have been fabricating a motor bracket and starter mount .
 WOW lots of cutting and fitting But it looks just like I envisioned and
seams to work .
 I have to be able to adjust the " attitude" of the motor 'drive.
 I still have to make the "Adjuster" on the front.
 It will consist of a one inch ,by three inch bolt and nut on a rubber pad
To move up and down and then a locking plate to hold it in place .
That's next.
THEN finally I can start the drive/hub/prop.

  O0 Really looking good, D! Your prop system should be pretty easy, huh?

Probably not! Figuring it out as you build can be a nightmare, yes?
Title: Re: Waterbug one more step
Post by: D45/70 on August 23, 2017, 11:11:43 AM
I have a good idea where I want to go with most the build ...It's the getting there that takes a lot of trial and error
Title: Re: Waterbug one more step
Post by: John Andrews on August 24, 2017, 04:02:45 AM
It sure would!
Title: Re: Waterbug one more step
Post by: D45/70 on June 17, 2018, 03:14:54 PM
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.

Sounds like you are getting down to the nitty-gritty of it. All these final details seem to take forever, but take the time to get them right and you may never have to touch it again.

 Kinda looking like I'll have to do a foot peddle or something, just not working .

Qhy not a long lever throttle like most wet prop boats ?

I'm thinking when your running 35 mph on an inch of water or an inch of ice you'll want both hands on the handle bars  :shock:

Well Dang!!!!
I have decided to give the snowmobile belt drive up...

I just don't have the RPM/HP to make it do what I want.

I can't get it to get up to a 1 to 1 ratio at 3000 rpm so I have to run

the bug motor up to closer to 4500rpm to get the prop in to the upper 2000 rpm range. When I do get it up there the belt slips a lot.

I got a shorter belt to see if there was a difference, much better but still not good.

    I got two 32 tooth #50 chain sprockets , same chain I use on the top drive, with 1 3/16th hubs.

They go right on to the parts of the SNB drive that I had made.

With the hubs I can change the ratio if needed with only a sprocket.

with a two stage chain drive I'll have to run idler sprocket on both chains I suppose. I had to put a key way in the shafts, amazing what an angle grinder can do. It is a little les forgiving then a belt as far as alignment. Hope to hit the gas this weekend and see if I can blow some dirt/gravel.
