Making Better Fly wheels
« on: January 08, 2006, 02:38:47 AM »
Hello fellow Listers!

I had a thought, I used to service cranes over at the Dana brake parts plant here and town and always noticed there was usualy some Iron left after a run. Has anyone ever investigated the possibility to have "Better" fly wheels cast?
Now I don't own a sationary yet but I this might solve a lot of peoples trouble. Also, having looked down on the process from time to time from up above I think a fly wheel might be the easiest part to have cast.

Doug,

It's not talking to yourself unless you use different voices.  Had a boss that did that a long time ago.  Weirded everyone out so much when she started that, they'd get up and quietly close their office doors. 

Re: casting flywheels, that's a REAL project.  Too bad you can't just make one out of fiberglass and carbon fiber filled with lead shot or depleted uranium.  That's more my speed.

Doug...Kirit Patel must be related to Atul Patel.....they are the Anand Enterprises people who produce the Powerline machines with all the upgrades for the N. American market. Ive asked them so many questions they sent me a Christmas card  ;D  I believe I've read somewhere they supply george and the people at listeroid but I could be mistaken.

I'm just curious here;
We have air pack bottles at work that are Kevlar wrapped for light weight strength.
I was wondering if the set of flywheels (that we are talking about but will not name) were tightly wrapped in Kevlar (or carbon fiber etc) with the apprpriate epoxy matrix, would it be rendered safe?
How would one calculate?  How much does cast iron expand before 'She's a-gona blow Cap'n!!'
???

There is no question that a rotating part can be wrapped in Kevlar for safety. However you will not be able to expand the operating envelope of the part. In other words, the Kevlar will not strengthen the part to the point that it will withstand extra stress.

That's what I was wondering, plus you would always wonder how the wrapper was holding up over time and exposure.
I was also thinking of a shrunk on steel band, like a starter ring gear or a railroad wheel / tire?
Best to order a set of 20" flywheels from a ? reputable ? source in India?

I may go over there on day and ask if the would do a small run of fly wheels. I don't think they would be that hard to sell...

I can just see it one day.   Chromed 24" flywheels with little blinking blue lights all around them with spinners going in the opposite direction.  ;D

The GM 90's are made by http://www.satyajeet.com/de2.htm I remember in one of the threads i read here they were making custom flywheels for a dealer. Perhaps they could probably quote you via email on the "extra heavy" ones you are thinking about making here? just a thought.

Yeah, I remember that too.  Somewhere else that same dealer mentioned that the flywheels mill better because their iron is consistent.  Is there some concern about the crankshaft breaking?  Satyajeet will likely fill an order.  There is the usual caveat that freight is relatively more expensive for less than a container.

Well, the dealer would probably quote you on the flywheels.  Perhaps back them up as well. How much more weight than a regular flywheel are we talking? Is it a spoked or a stover type? These are some options as far as I can tell (and you probably already thought of this too):
Contact Sensitive Industries directly or
Call Mike Montieth (GM90)
Call George B. see if he can get custom ones.
There are other dealers that may help. Here is an off-the-wall suggestion, because I am a lunatic at heart: Look up "Lindsay's Technical Books" on the web. They have plans to make a "charcoal foundry" that works good. I made one years ago. You could sand-cast your own flywheels and a few extra. Not that technical of a thing to cast, if you study it a little.... ;D

just got thru checking my listers spec. sheet // about the only difference between the 6 and the 8 hp is the weight of the flywheels/ my 8 has a little heavier flywheels. the bore and strok are the same/ the speed is a little greater on the 8 but it appears that the only difference is heavier flywheels.. I had the opportunity this week of visiting a friend and fellow engine collector/his count is 180 engines ++  and 10 tractors/++/ he has a gm 90--6 hp mounted on a 1000lb block// it shuck the block// I can run my 8 on a trailer// so i guss the weight of the flywhels do make a difference//I have seen some impressive engine collection but this one would be hard to beat/most of these were not your every day common antique engine but a large collection of very good and rare pieces of machinery// it did not stop at engines and tractors.. it included almost everything/he has been putting this together for at least 30 years. I doubt that it could be dublicated now// sid
