IBLS Standards,

[IronMan]

Hi Guys,

Well it stands to reason that once I have almosts finished turning my wheels, I came across the IBLS wheel standards. In the book the 3 degrees is the angle for the flange the standards are 2.5 max. I dont beleive it will affect the the wheels at least I hope it does not. Because they are mostly done. Anybody turned them at 3 * ? any problems ? or anyone done previous wheels on other projects using .5* more ? Thanks in advance for any information on this.
Cheers

Does the standard not read 2 degrees 50 seconds?

[IronMan]

Yes, Looking at it does, now I know how to read seconds.

Thanks,
IronMan

Dear Group,

Here is a link showing some IBLS standards.

Perhaps the chart will help someone. Please remember I have just got interested in this hobby, so someone with experience should comment on whether or not the information is correct.

BTW, this is from someone's site not mine.

I cut them at 3 degrees, screw it, it'll work.

As near as I can calculate, the difference in radius at the outside edge of the tire when using 3 deg instead of 2 deg 50 min is all of 1 thousandth of an inch. I don't know about you, but my machining "skills" introduce more error than that!
