What size of ball hone do i need? The manual says the bore is 3.74in or 95mm. I have the option of 3 3/4" (95 mm) or 4 1/8" (105 mm) both 180 grit.
Out of the two witch would be better? I read some where on here that it should be 4 to 4 1/4 and i read some where else on here that you wanna get the 3 3/4? :cheers: thanks!

And for those who say i cant hone it.... :banghead:

FYI. go easy on it with the hone. your not really supposed to do it. However a gentle clean up should be ok.

Check back with us after the work is done. I have run a loosely fitting bottle-brush hone through a plated cylinder once up and once back with no major problems, but a real 'hone' might be a bit rough on the plating.

Yeah, a real quick and lubed hone should be alright. Just enough to de-glaze and re-crosshatch.

4" would be ideal, but since that's not an option, use the 4 1/8"

thanks gray! Should i shop around to find the 4inch? This was just what i found on the Snap-on web site, I'm going to ask my Snap-on guy if he can get the 4inch.

Unless you have a really good reason for buying it from Snap-On, you might want to Google Brush Research regarding the hone. They don't make them in 4", but they are, as far as I know, the source for Snap-On, and should be much less expensive.

I have a credit line with snap-on so it makes it abit easyer and he priced the 4 1/8 at $50 as to the local tool store wanted to order me one for $67. And i figure the snap-on will be better then the no name from the tool store. I will google Brush Research and see what i can get one for from there. Thanks again!
