I will order them, and begin fooling around with files and nonsense until I've either made a mess, or have some functional spline mounting freewheels
etard said:Gary,
on the port runner I see you are using a metal large sprocket with a 7 tooth motor sprocket. May I ask what size is it, is it heavy, and what material? It is not extron correct? Have you thought about getting it lightened?
etard said:On another note, I thought your adapter was going to slip onto the three prong mount on the hub directly and be more stout than the stock 16 tooth cog, but now I see. I just question the power handling capabilties of those small teeth to handle much power. But if you are running a 3220 through it in this manner with no slipping or wear I suppose I will order up an adapter this week. ]/quote]
The 16T Nexus cog is made from hardened steel, so it is already quite stout. Matching it with a lightweight, but heavy-duty go kart racing sprocket seems to work quite well. The drive sprocket on the motor is 11t, not 7t. Even there I think a 12t would be better/quieter. I had a 7t on the original Cyclone setup and it was noisier than hell. Frankly, this isn't all that much quieter. Great power, for sure, but this setup is far from stealthy.
etard said:Thanks for this pics, maybe they are somewhere else, but this is the first I have seen. They let you on the metrolink with those bikes? I want to ride the Santa Ana river trail into Huntington beach and then ride th train back home one day, I just don't know how to get my bike back home. :|

I will make a jig using sprockets clamped to the freewheel's inner portion, and carefully work it with a file until they slide on the splines.

Excellent concept IF the SRAM Dual Drive is strong enough for your system.liveforphysics said:I'm going to buy the sic bikes eno freewheel, and a regular freewheel, and the dual-drive hub, and make the freewheels fit on the splines by hand with a file.

GGoodrum said:These are hardened steel and you are going to hand-file them? Sounds like a lot of work.
If it works, it will definitely beat having to pay for a quantity of 100 to get Doug White to do it.

Allows you to run any 74 or 58bcd chainring(s) on your cassette freehub body. $40
If you have ever tried to cut a pipe straight using a Sawzall, you know how difficult it can be. Milwaukee created a tool to battle this and help the user create more accurate and straight cuts.
The Pipe clamp system will hold up to 4″ pipes and is designed for their super Sawzall line of power tools.

Certainly, the ENO freewheel has a 36t ratchet, as does the Echo.Miles said:If the number of engagement points on the freewheel has a factor of 9, you can use the freewheel mech. to register the spline positions for filing. Then, all you need is a guided file slightly wider than the driver splines.

Asking to see how the 3- speed hub is holding up? AusieJester mentioned that Safe broke one at 1K watts.
I hope yours is going to prove worthy. I have some plans & would love to hear any updates bad or good.
I will search for the thread where safe lunched his. Thanks, Todd.
