2/3 scale Indian Straight Four.

[Repliconics]

The drum brake is about as finished as I can get it at the moment.
I haven't been able to find a picture that shows how the brake pads are locked onto the posts.
I'm guessing it would be with washers and split pins or a type of circlip.
But until I find out I'll leave them as is.









I'll get on with setting the drive sprocket on the other side of the wheel.
That will be interesting!
Way back when I started building the frame I realised that the chain was going to be misaligned.
The problem comes from the scale of the hub not working out right when using a bicycle wheel
compared to a motorcycle.
So when I get the sprocket set on the rear wheel I'll know how much I need to cut out of the gearbox
to straighten the chain.
Not looking forward to that but at least after the sprocket is set I'll know how much trouble I'm in.

Cheers
Trev.

Beautiful work

[Repliconics]

I've modified the sprocket and spacer I got from Joe.
The sprocket needed to have eight unwonted holes in it filled in and some metal removed from the inside
to make the radius arms look the same.



The spacer that he made me on the spot from an old compressor part needed to be shortened a little.
It's a bit a of balancing act to try and get the sprocket as close to the wheel as possible, but at the
same time keep in mind the closer it is the more the gearbox will need to be cut down.
To get the alignment of the chain right.



Hopefully I'll get the sprocket mounted on the wheel today and I'll be able to see just how much the
gearbox is going to need to be modified.

Cheers

G'Day Trev, The bike is continuing to progress, WELL DONE SIR....
Only one question, I thought you did the gearbox modification some months back???
Cheers crowie

No mate I've been aware of the problem for a long time.
But until the drive sprocket is set on the rear wheel, I have no way of knowing exactly how much I need
to reduce the gearbox by.
Not something I've been looking forward to!
But that's the way it goings when your mucking around with scales that don't match.
I'm really glad that I stuck with using bicycle wheels instead of motorcycle ones.
But it's a bit of a nightmare trying to get it right.
It's also half the fun

Cheers mate

After a long day of modifying parts and juggling things around I'm only 12mm away from having the chain aligned.
I've moved the engine across to the left as much as I can.
The sprocket shaft on the gearbox has been shortened which also helped.
And I widened the distance between the rear axle carriers by 20mm.
With all of that I managed to shift the alignment of the rear sprocket by 28mm to the right.



The down side of shorting the shaft on the gearbox sprocket if that it makes it harder to fit the chain guard.



I made a dummy hub out of PVC which made it a lot easier than having the wheel in the way while trying different things.
In the end I came to realise I was shuffling deckchairs on the Titanic!
There's no way out of having to cut down the gearbox.
But the good thing is I only need to reduce it by around 15mm to align the chain and have room for the chain guard.



A 15mm reduction in the gearbox wont make any real difference in the appearance of the scale being correct.
So I'm calling it a win.
The funny part of the day came when I realised with the bits and pieces of bicycles and what not I have laying around.
At the moment a chain is not one of them!
So you know who's going to be the first through the gate at the recyclers in the morning.

When you set out on this project did you have a set of photos and rough plans with dimensions?

I ask this because it seems such a waste of time to have to continually modify parts already "finished".

The brain exercise is probably a bit taxing too!!

I am still totally amazed by your achievement.

So you know who's going to be the first through the gate at the recyclers in the morning.

If you left just after you put this post up you would definitely be the first through the gate. You've done half a days work before I even think about hitting the snooze button. At least it gives us something to wake up to.

A couple of really good question with no real simple answer other than to say high functioning autism.
It's something I make no bones about.
And I'm very happy being that way it allows me to build the way I do.
But no amount of neuroplasticity will fix it

When I started the Indian I had a few pictures from the internet.
But I don't build from plans (they get in the way)

The reason for the modification of parts is more one of perception.
To me they were never finished at all.
Or maybe it's better to say none of the parts of the bike are finished until the bike is!

I don't find it taxing at all, in fact to me perfectly natural.
But I can certainly see how some could find it a little odd.

I'm really glad you like the work.

Well that being the case best I say Good Morning mate

I got to the recyclers pretty early the only one in front of me was a sparrow.
Who apparently had a bad case of wind.
It took a hole two seconds to find a chain.
I can't believe I didn't have one on hand.



The chain fits just fine but that 15mm of misalignment may as well be the Grand Canyon.
It's got the biggest Woof in it since The hound of the Baskervilles!



Still it's not the worst when I strip the bike for paint I'll cut a slice out of the gearbox behind the sprocket.
That will do the trick.
Then when the chain guard is over it everything will be nice and straight.

Trev you disappointed me. All those bits you made and you go and use a chain instead of making one from wood

OK I forgive you looking great as always

[Repliconics]

Your right mate I've dropped the ball on that one.
But at least I'm honest I could have sprayed it in primer and said it was mahogany!

Cheers mate

At least with the hours you keep you get to corrospond with our friends abroard in a timely manner.

I'm working on the stand for the rear wheel at the moment.
Not the most exciting part of the bike, but the one you least hope to brake!
So a bit of time will go into making sure it's strong enough to do the job.



The bracket with the hole in it will go to the top of the stand.
I need to get into it with the grinder, but that will have to wait of a more civilised hour.

In the meantime I've plenty of work to do on other parts getting them ready for paint.

Cheers
Trev.
