Does anyone know "exactly" what material the comet 94c pucks are made of ??

Anybody ?? -------- hello ------- hello -----

Based on info I have found online the pucks are probably natural nylon. The cost to manufacture and sell works out to $4.50usa a piece to make (that's what it would cost me). Not including shipping. The pucks I have found online cost $11.50usa a piece (cheapest ones I found). Not worth the effort in my opinion. I was just fooling around anyways. Below is a pdf if anyone wants to look.

Once again trying to think outside the box (failure IS an option according to me).
Decided to play around with this a bit more.
I ordered a sheet of material and cut two pucks.
The first one is a bit under size so this is the one I cut up on the milling machine.
Ran into an issue. The sheet of material is .520 thick and the 94c pucks are .490 thick.
So I ended up milling off .030 so that it would fit.
If you look at the pics you can see that the stock puck is worn at an angle on the engagement side. I bet many of your units are the same.
You will also note that these replacement pucks are a lot lighter based on my dope fink scale.
The original is 23.5 grams.
The one I milled is 17.6 grams.
The unmilled one is 20.5 grams (this one will not fit in clutch).
So it looks like I will have to add weight or just run a lighter puck . This should bring the engagement rpm up. Remember the oddy has it's best torque at 6000 rpm. I will have to look on my computer to see if I got any info in puck weights/engagement rpm.

help me understand what the pucks do? You are trying to make your own to match the stock, or trying to make a pick that would add better performance?

The pucks lock up the clutch so you move foreword.

1) Personal challenge.
2) You can make custom weight pucks so that it takes a higher rpm to engage.
3) I wanted to make my own because if I buy off the internet it's all in usa dollars and when you convert to Canadian plus shipping I get ripped off.

Edit: A good example of this happened to me today. I was looking on a Canadian site for a leather apron to use in the shop. The coveralls are to warm. I found one at a place in the big city. It was $10. Shipping was $15. F that. Keep your junk. Shipping was free if I buy $100 of stuff. F that too. I don't want $100 of your crap. Now imagine if that was in usa dollars and had to come across the border !!

I currently have a 102c on my machine. But I have two 94c on the shelf as spares. On one of them the faces were worn so I put it in the lathe and refaced it. The pucks on that unit are also worn at bit of an angle. My plan is to make some light weight pucks to bring up the engagement and install on my machine.
I am just fooling around in the shop since I don't get many opportunities to go riding. My brother hasn't been on a run since last July and on the only ride so far this year, I put my buddy in the death machine. I own three FL350's.

Based on info I found on my computer, puck weights and engagement --- if I run 6 of my 17.6g homemade pucks engagement will be around 4000 rpm and if I run 9 of them it will come on at 3400 rpm. That's just guessing though based on my suspect math.

Actually quite happy about how they turned out.
Made 10 of them. Milled 5 at a time.
One set is 19.80g and the other set 19.30g.
So one set is half a gram lighter.
I still have to mill .030 off the thickness on each one, so they will get lighter.
Also have to round the corners and that will take off a bit more grams.
Since these are going to come in around 17g I plan on running 9 pucks with the orange spring. That will get me near the 3400 rpm engagement.

I have removed my 102c and installed the 94c with these homemade pucks on my machine.
Also ordered and installed a "white" spring. Unfortunately there were some issues as the springs that were sent to me were very poorly manufactured (pics below). I did install a white spring anyways and I am running 9 pucks. Based on my best calculation with these weight pucks and a white spring, it should engage at 3650 rpm approx.
We can't go for a run here because the whole province is on fire. There are over 600 fires burning right now caused by lightning strikes. The smoke is so thick it blocks out the sun and it has been two or three weeks of this crap already. The province has declared a state of emergency. I don't foresee going for a ride until late September as there is no real rain forecasted in the near future. That's two years in a row now this has happened in our area of the world. It's very unusual weather for us. There is a fire across the river from me but no chance it will reach me. There is a helo base half mile from my house and they are flying water buckets.

Well since it is dinner time and the local constabulary is probably having dinner at the local donut shop, I decided to test run my machine down the street.
I kept an eye on the tach and it locked up at approx 3500 rpm.
It ran great. I also think that running 9 pucks in a 94c is way better than running 6 pucks. The reason I say this is because the launch seemed to be better. Maybe it's just me but it did seem to launch well.
In my opinion I bet we are getting slippage with 6 pucks.
The machine was run on pavement with new tires.
So at the moment I say run 9 pucks at 18.5 grams and white spring.

On a positive note with todays ride up Hunter creek, my homemade pucks worked perfectly.

From Topic "Machine won't run" Thought I would move it hear

""my machine would not run going up hill or when you got on the throttle.""

? were you running the your custom copy pucks in your machine or both

There reason I ask this. Your oddy was bogging down correct, but on the flat went ok


wyeeoddy

I don't think I explained it right in that other thread.
The oddy was not bogging down.
It ran great and then started giving me trouble. It didn't really matter if I was on the flat or going up hill. As soon as I gave it ANY throttle the Engine would die. If I just let it idle it would run. It slowly started getting worse and worse until it got to this point. When I got home the fuel flow rate on the pump was only half oz in 10 seconds. When I back flushed it with air my flow rate from pump went to normal. It now runs good again. The problem is my fuel pick up I made. I just drilled a hole in the drain plug and mounted a fitting. My original pick up lines were corroded up. What I should have done is what I did to my brothers machine. I added a small tube to the end of the drain plug. That way it don't pick up poo from the bottom of the tank. My bad. Will fix that this winter, not now. Best riding time of the season for us right now as the weather is awesome this time of year. Plus a bonus -- hunting season.
My homemade pucks work. I slowly feed throttle and then at about 3600 - 3700 BOOM it locks up and launch's.

Just an update on this project.
I have been on several rides now with these pucks and they work great. No issues yet.
Think I will make more of these this winter.
Have a lot of projects I am thinking about for this winter but don't know if I will get to them all.
Thinking about: Homemade CO-500-X two stroke, more homemade Engine mounts, intakes, aluminum casting (revisited), unknown .
I'll have time for some of this stuff cause I'm gona quit my job soon. They don't know it yet .

Great work as usual CO. Very interesting thread.

This thread is over a year old now ------------ god I'm getting old. It was fun doing it though.
Will try to finish up that clutch thread tomorrow if nothing else comes up.
I feel and think that anything a factory can build, we can build. It may not be perfect but it will be godamn close, but more importantly it must be functional.
If it's man made it can be copied and reproduced. The only thing that can't be made it something that has been born.

Decided to pull this clutch off tonight. Bored I guess .
It was working just fine but I wanted to know what it looked like after a year of riding and also wanted to know if my clutching was off. What I have been noticing with this clutch since install is that the bottom end was great and so was the top end but as soon as I had to go up a steep hill (that's most of em around here) the Engine would kind of power out as the rpm dropped suddenly at full throttle.
I am running the white spring with 9 of my homemade pucks.
The rpm has to come up a lot before it engages and then suddenly it launches. It powers out going up hill. Maybe I should try 6 of my homemade pucks but that would probably really bring the rpm up.

So now I am running a stock 94c with orange spring and 6 factory pucks.
This will tell me if my clutch is the issue or my jetting or if the hills are just to steep.
We plan on going for a ride tomorrow. Not sure where yet but I hope Hunter Creek.

In the pics below you will see I am running white spring and 9 homemade pucks.
You will also notice that there is NO WEAR on the pucks.
You will also notice that the square hole has been pounded out a bit. Probably from those sudden launches when the spring and pucks engage.

Well it's real obvious to me now that my clutching was way off.
We went up the same valley to make sure we are comparing apples to apples.
The stock 94c clutch worked perfectly for me. The machine had power all the way through to full throttle.
That experimental clutch with the white spring and homemade pucks was way stronger on the bottom end but fell on its face at the top end going up hill. It just dragged the Engine rpm down.
So the comet 94c with the orange spring and 6 stock pucks works well for our stock engines with a pipe.

So maybe next riding season I will try the experimental clutch with white spring and 6 homemade pucks instead of 9.
This is the best riding season here now for the next two months weather wise so I don't want to F around with two well running machines.

By the way I did mill off 1/8" on both of these clutches to close up the belt to shiv gap.
