English wheel anvild
How close to perfectly round do the english wheel lower anvils need to be. My upper wheel is within .001. I haven't checked the lower ones yet.

I would think that the closer to round the better you could move your metal.
bumps and dings or grit on the wheel transfers to the metal .

Hi,
Roundness and runout of .001" is just fine for a wheel. B

Due to the lack of time when machining some wheel, I use somethings the weights from the gym, but the result of the work is not recognizable. Of course, minimal wheel runout is required.
Large frame strength is required.If you use rigid frame immediately feels what the material is telling you. No stress. http://allmetalshaping.com/showthread.php?t=17702

Ewheel stiffness
Jaro is correct. It depends on the stiffness of the Ewheel frame. Just like a production car with soft springs, you don't feel much of the road. A race care with stiff springs will tell you if you run over a coin. Likewise, any runout in a racecar wheel will transmit to the driver. Being from Minnesota, I have seen cars with ice in the wheel making it hop all over. The Lexis driver is none the wiser. A soft frame will probably tolerate .010" of run out. A stiff frame won't even roll with that much runout.

You can definitely feel .010" of runout on my Horrible freight wheel. Cleaning things up made it much easier to use.I was able to bring it down to .003-5" error which feels ok.
Wray Schelin has a video on his YouTube channel about dressing wheels and he shows how to true them without a lathe.

Thanks guys. All useful information. My English wheel is a less expensive model. Not super stiff. It is larger than the yellow HF one. My lower anvils are all .003 out of round. I'm going to try them as is and see how they work. Thanks again for the info.
