Ian

It's evolving.... What's it gonna be like next week

That depends if I can work out a way of driving the diff directly on that big blue Peerless trans I have

Thank you Karl and Nigel for arranging for me to have a drive on a Racing Wheel Horse at The British Lawn Mower Racing Association race at Hawkhurst, Kent 22/6/14

Are you using your van as a mobile workshop or is the project hidden from the missus?

A nice find Chris, I like that the key is in the ignition switch but it has no engine

Smaller rear wheels? That helps with the gearing a lot! Top speed will be about 2/3 what it was...

Nope, they are the new front wheels

The rear wheels and tyres will be staying the size they are, in my eye's "Why Not" just wouldn't look right without them

I managed to grab a couple of hours in the shack today, and thought I would mock everything up at the correct ride height to get some measurements.. The chassis has 4 inches ground clearance at the front and 4 1/2 inches at the back

Just pile it all in place and work it out from there    The Wh trans won't be staying, I just hadn't got round to unbolting it.

Oh, and the angled drive thingy from Nigel will now for part of the steering system.. With a smaller mounting plate on the base of the unit I will be able to run the steering shaft under the engine

It's looking good Mark... So when are you offering a Diff lock kit?

You won't be short of winter projects with that lot

Nice finds Paul

The Honda is no more....  As I'm using part of the bike frame, all the unwanted part got trimmed off leaving this..

And while I was in the shed looking for a box to put bike bit's in, I found these "deep dish" wheels that I think were on a C series Wheel Horse at some point.. Much easier to make bolt on able and will give the beast a slightly wide track..

That's a cool project Ben, looks like a lot of fun.. Don't forget the video when it's driving

Sierra/herald type diff,chain drive to seperate axle shafts with a method of locking them together, cheap difflock.

That's some interesting thinking, a lot of work and weight though.. And with less weight at the back I stand more chance of keeping the front wheels on the ground for longer

Nutley is near a windmill Nigel

Years ago I replaced a missing cooling fan on an Eaton 1100 trans (in a Wheel Horse) with one the same size from a small household fan. It worked a treat     Just a thought..

Sounds like your have it running tomorrow Chris

Looking great! Once it's finished don't paint it! Have a rat rod,

Instead of the normal... Taking rust away, make rust, have a nice looking rat rod. Get the exhaust pipe chromed, make the rear rims wider have wide semi slick tyres on the rear, one of them fancy looking chain steering wheels, there's so much you could do to.. 'Tart' it up, or then again you could paint it, stick a few racing decals on there with a racing number, either way this will look great!!! Top work,

Thanks Charlie, I'm undecided on the paint at the mo, I quite like the "Rat Rod" look, but I do have a few radical ideas on a very different paint job...   I'm also itching to break out the airbrush again, it's been so long since I last did any.. Anything could happen with the paint at this stage

glad to be of assistance and I think the new plan is more sensible than using the wh transmission...

 

plus who needs reverse

I'm not sure if the new potential top speed of over 100mph is  sensible, but I get what your saying

I need to get some small switches wired into the heels of my boot's, connect them to a beeper.. That way every time I push the beast backwards from the seat with my feet......

I'm guessing it once contained oil Mark

I'm feeling a bit unsteady today, so rather then start using tools that produce hot sparks I'd have a gentle potter in the shack and move a few bit's about on "Why Not" to create a bit more drive shaft space..

The front axle moved forward of the hood and the engine slid forward as much as it could.

The engine will go even more forward once the front axle mount is out the way..

But it gave enough space to show the two prop shafts could be lined up and made into one..

How about making an extension for the output shaft? You could fit a supporting out rigger.

Here's why the angle gearbox drive doesn't need an extension Norm..

Line the angled gearbox prop up with the shaft on the bike trans..

And the angled drive gearbox would stick out so far the pulleys don't stand a chance of lining up..  Not that any of that matters any more, your see why in a min.

While I had the Honda's final drive to hand I stuck it on the end of the drive shaft to have a look... It almost lines up with the Wh trans pulley

But due to the final drives gearing it would give a very slow top speed... Oh, and a lot more reverse gears than forward

And then Mark who has been kind enough and also has the maths brain power that I'm lacking came back with a few calculations for me!   It's the final number that hit home!!

That sort of top speed from a 48hp V twin would just be embarrassing, and could be got from a 10hp Kohler with a lot less work!!

Looking at the final drive on the end of that shaft did get me thinking though.. If the final drive was bit further back to line up with the Wh trans axles then maybe it could be used to drive a cart axle!!

Yes it's the same photo again

So, off to the shed I trundled and grabbed the Honda's rear wheel to unbolt this bit..  It shouldn't be too hard to get a sprocket to fit that

And that bit happens to slide onto the final drive

Sooo, the new plan is to use the Honda's swing arm and final drive then take power back from there via chain and sprocket to a rather strong kart axle.. I can even use the Honda's rear brake which is more than up to the job and very easy to fit

The new plan kinda moves this build up a few levels as it could be very easily geared to reach the bikes level of top speed or even more should the suicidal urge take me!!

I'm happy to gear it for a bit less top speed but certainly more than 14.20422 MPH

Oh, and while the front axle was off I lowered the front end quite a bit to see how it looked

I think a rotovator of some sort, my thinking is anything that can cope with the stresses of rotovating must be quite strong

Which output shaft are you talking about Norm? I have the shaft drive from the bike gearbox.

Spacer between the trans and the frame? or fabricate a new rear part of the frame to extend it and carry the 90 deg box

It would have to be a rather large spacer       As I'm going to chop and lower the chassis it would be easy enough to slip in an extra few inches while I'm at it.

 I've been looking at that photo, Ian. Would it be possible to shorten the Honda drive shaft behind the UJ, machine a sleeve/adapter to fit the angle gearbox and weld it to the shortened shaft? You would only have one UJ then.

I get your thinking Norm, the trouble is the angled drive unit thingy has to be offset towards the middle of the chassis to get the drive lined up with the WH trans.. So 2 UJ's are needed.

Good luck with your search Chris, but I fear you may have trouble finding "D" parts unless you look state side..

The odd "D" does come up on that auction site, but I've never seen any "D" spares!

A nice find Ben, I like the "space age" look....   Would look really cool with the ally body (it looks like ally from here ) polished up

ive got a small extension with ujs ian that should fit onto that would give you another 6" if you need it

Thanks mate, length is a problem.. I have too much of it

A bit of a slow day in the shack today, feeling tired after yesterdays chaos with Garry's trike, but other than finishing cutting the grass I did manage to get a little bit done one "Why Not" today..

The angled drive thingy from Nigel (thanks mate) was cracked open to see what needed freeing up...   Dry as a bone inside other than a quick squirt of WD40!

So I filled it up with stuff that smelt like diesel, though it was a funny colour!  An hour later it had freed up

This is where my length problem comes in!

The angled drive is near as as I could wedge it in it's new position, and the prop shaft that slides onto the bike gearbox splines is full on!!   Not enough space to cut and shut the shafts together!

There is enough space to move the engine forward and tuck in the front of the hood, but.... The front axle would be in the way!!

I don't want to lengthen the hood, but maybe I should move the front axle to in front of the hood to make the space!.. Dunno

Also trying to work out how to get the center of this wheel..

Into the center of this wheel...

So I can fit wheel hubs on the front which will give me somewhere to fix one of these....... Thought a pair of them on the front might come in handy

Good work Mark, though I'm sure your just adding a diff lock to give you an extra lever to play with

Fantastic photo's, thanks for posting them..    The tipper tractor thingy really floats my boat

Great photo's Mark, ta for posting them

I found a couple of photo's of the racing WH I forgot about on my phone..

If you are thinking you have seen it before, you would be right.. It came from the great engineering place known as Nigel's workshop
