Hey T,

For reference, this is a pic of the 75T sprocket that I told ya about
...also, gots a 84T sprocket too

Here is an old thread about Power Curve Sprockets (10T x#35)

Remember this Ez?

I used the CAD template(s) on a piece of 11g steel (just a "hair" thinner than 1/8" thick)

Ducky helped

Traced 'em out

Cut 'em out (rough cut)

Clamped 'em together
...to "true" 'em up

Now, they pretty much match

Another "kooler" view

Remember this Ez?

Sure do.

Ducky is getting quite chunky.

Hey Denny,

Yup, that's my Ducky

She's had a couple of litters of kittens
...& now kinda middle aged

* I've noticed that wherever I'm workin'
...seems like the best place
...for her to take a nap

Thinkin' about makin' some kinda "jig"

So, I rounded up a piece of 1" square steel tube (1/8" wall thickness)
...& a piece of 2" square steel tube (3/16" wall thickness)

Then, cut a couple of pieces off
...&/also, did some creative notchin'

Jua'lla asked...what kinda "jig" ya makin'?
...& what is it gonna be used for?

Here is a hint...1" + 1" = 2"

 

[Functional Artist]

Well, if we stack the shorter piece of 1" square tube
...on top of the longer piece of 1" sq. tube
...then, stick 'em inside of the 2" sq tube
...& weld 'em together

We gets something kinda like this

Yup/of course, it's Made in the USA

I can tell by the poor quality.

QC in Japan:

Here is the issue with redrilling the rotor to match the hub. The hub has a 2.75 BC. I think the bolts are going to interfere with the caliper.
The other problem is the flange on the hub is much bigger than the 2.75 BC. (BC=Bolt circle)
Lemme know watcha think.

Awe, just use one of the other sets of holes.

Hey T,
Well...

This is a pic of the brake drum, that came off of that hub
...&/also, the caliper I'ma wantin' ta use
* The brake pad seems ta be ~1" wide

This is a pic of how the caliper looks "mounted" over one of them small rotors (on the rear of Sequoia)

Q:
If mounted, on that hub, how much of the braking surface would still be available?

 

[Master Hack]

how is this mounting to the hub? I know, on the 4 studs. The hub has a flange that is approx 3.25 inch diameter, so that covers a good portion of the braking area.
am l missing somethinh?

 

[Functional Artist]

Well...it was just an idea
...& not all ideas come to fruition

Any ideas?

 

[Master Hack]

What is that hub going to do? The sprag/sprocket is on one of the wheels. Other than the rotor what is going on that hub? anything?
Also do I have 3 or 4 wheel halves? I have 3 did I misplace one? If so I know it didn't go too far. Memory....

 

[Functional Artist]

Sorry for any confusion
...that hub & rotor would be for a whole 'nuther project, my Hellraiser kart

The drum brake set-up can be seen in this video

I just included it in the box while I was sending ya another black wheel

Yup, I sent ya (2) of the black wheels (so, 4 halves total)

 

[Master Hack]

Back to the "other" hubs....
We have a dilemma A video is worth 10k words.

I'm don't know where to go from here. as you cn clearly see the whole wheel runs out about a mile!

 

[Master Hack]

On the subject of run out, this may cause chain derailment?
