Yes, when you think it can't get any better, Trev just amazing you again with some magic.......

Thanks for the kind words I'm glad your still enjoying the build.
Although at times it's driving me a little nuts.
At the moment I'm trying to workout the best way to arrange the rear wheel.
I need the wheel itself to turn freely while everything else (the drive sprocket and the drum brake) stay still.
The speedo drive is mounted on the spokes so it obviously has to turn with the wheel.



While I was at Joe's he made a spacer for the Drive sprocket out of an old aluminium compressor part.
It gave me the idea of isolating the drive sprocket and the drum brake by having them on their own posts.
Which would be screwed to the frame itself.
I'm not to sure that my drawing below will make to much sense, but hopefully it gives some idea of what I'm thinking.



The red section is the frame and the light grey the hub.
With the posts mounted either side the idea is that when the through axle is removed the wheel comes away,
leaving the brake and the sprocket in place on the frame.

At the moment I'm pretty confident that it should maybe kinda work!
But I'd be more than pleased to hear of any ideas or modifications that improve on it.

Cheers
Trev.

I haven't dropped in here for a while but I am still stunned by this build!!

This looks so real it is uncanny.

Brilliantly done sire!!!

I got a start on the rear brakes.
Their the early style of drum brakes having the bands on the outside.
When you'd put your foot on the brake the bands would contract down onto the drum.



The picture below is what the brake should look like when finished.



So far I've made the drum, the mounting plate and what will be one of the brake pads.
In the picture below the brake pad is sitting over the drum which is in primer.
I need to make some metal straps to go over the pads.
I'm hoping the sides of a coffee tin cut down will be thick enough for the job.



The brake pad is 3mm MDF that I steamed into shape.
I'll make another one today then cut them down to size.



Cheers
Trev.

Hey Trev,


The rear sprocket looks great in position. Looks like you are really getting your teeth into it !!!

Hey mate
For a guy who wasn't to sure how puns are structured you're a fast learner!
You almost seem to be "chomping at the bit" to use them

Glad you like the speedo drive sprocket after making it I've got a hole new respect for your work on the Peny-Darren.

Cheers mate

Been a while since I stopped in and I am even more impressed than I thought I would be. Great work on the drive gear and brake. I have one question though. Where did the drive gear from the tranny go? Wasn't that on the other side? If so, isn't the wheel on backwards?

[Repliconics]

Hi Johnnie
Good to hear from you mate hope your well.
I dropped the drive the other side while I'm working on the brake.
At the moment I wouldn't be to surprised if the wheel was on backwards.
I'm having a great time making all this stuff.
But it's a headache scale is out the window due to the bicycle wheel being so different to a motorcycle.
I'm just trying to make things look as if they may work
Still it's all good fun!

Cheers mate
Trev.

Absolutely amazing work Trev. Glad I stopped back to have another squiz.

Cheers, Ian

Thanks for that Ian glad you like it.

Yesterday I got quite a lot done with the rear brake pads.
I had to give away using MDF as it wasn't standing up to it,
So I made some out of PVC their a lot stronger and hold their shape really well.





The rivets are nail heads painted up they should look the part.
Today I'll hopefully get the lever made and I can connect it all together.



After that I need to mount it all on a post that keeps it isolated from the movement of the wheel.

Cheers
Trev.

That is fantastic work. Your eye for detail is unbelievable. I thought the only break you took was a coffee break (brake) and now you come up with this.

Can't wait to see the next component.

Oh my...the bike parts are just getting better
BUT other things are getting worse.... .........

[Repliconics]

I don't know Crowie I reckon if you've got a new toy this is the right forum to show it off.

I didn't get the brake lever finished yesterday but it's basic shape is there.
It took awhile to get the position of the holes right.
But I'm pretty happy with it.
When you move the lever the brake pads close.
Not that it matters it's not as if it needs to work.







I should have the brake done today.
It shouldn't take to long depending on how many times I stop for coffee.
Then I'll get to work on positioning the drive sprocket on the other side of the wheel.

Cheers
Trev.
