Chains ...again...
« on: September 29, 2008, 04:43:14 PM »
Just a query for those who have done this before...

Im about to make up the plug for my chain case casting and before I add mounts to it....

Just how long are we aiming at making the drive chain to the transmission input sprocket?

As long as possible I am guessing???? Naturally this will impact upon where I add the mounts.

Have read so much about the problems re overheating chains yet no one has mention the length that will reduce this issue to liveable levels.

Also, if anyone is interested in casting matters I was thinking about starting a thread to showcase the process (if there is any interest, btw, it is ridiculously easy). Let me know.

Post away, we like everything...Not sure on length, basicly as long as possible, are you oil bathing the chain?

The cassette chain will be, yes. Ok, will do, starting the process in the next couple of weeks.

Hi Mastfab, I hadnt intended detailing the cassette construction itself, thats been done so often before (as you have eluded to). No, I was more wondering if some would like to see the aluminium casting process in detail.

I did see your thread and its because of the cost of your silent chain that Im pursuing the roller chain option. That, and the fact that I need a particularly narrow cassette requires it to be a custom job and a suitably wide silent chain prevents me from going this route.

Unfortunately Im limited to a certain wheel track by our regs over here and to allow me to use longer arms Im narrowing the drive system.

My query was did anyone know just how long the external chain requires for sufficient cooling flow/time?

I understand where you're coming from. BUT, my "casette" portion is only 4.5" from cv flange to cv flange for a total of 7.5" from cv face to cv face. Pretty narrow using a 3" chain,huh.           Part of the reason I went with the silent chain is that to enclose a roller chain of the same reduction the roller chain case would have been approx 4 " larger in diameter.  Your detailed log of the casting process will be an interesting read.  Looking forward to it.I'm curious though as to why you are doing a casting for a one off?

Curiosity killed that damn cat!

Why the casting for a one off?

1. I have a foundry.

2. I enjoy casting/creating.

3. Its cheaper than a billet lump and heaps of milling time (my mill doesnt even know what a computer is).

4. My creative juices are flowing. ;)

That's cool. My former inlaws also owned one ,made a bundle when they sold it too!
2. I enjoy casting/creating.
Same here ,that's why I'm doing castings.
3. Its cheaper than a billet lump and heaps of milling time (my mill doesnt even know what a computer is).I understand that also.My first one was done on a DRO manual bridgeport. It takes a lot of patience for a person without any to do it!

4. My creative juices are flowing. ;)

We just can't help ourselves can we? ;D ;D

Sorry Mast..i must be a bit dull today... 4.5" cv flange to cv flange? That is remarkably narrow setup.

I bow in your general direction!!!

still confused...the 7.5" is that the face that the cv bolts onto? or is that what you are referring to with the 4.5" measurement?

The reason I ask is I am down to 6.25" from cv mount face to cv mount face... and that took some work!

4.5" the face the cv bolts to .The outer faces of the 930 cv's are 7.5" outside face to outside face. ;) I'll leave it to you to figure how I did it for a while. ;D
