Drill speed for flex hone?
 

The directions that came with the FLEX HONE recommend 500-800 RPM; my Milwaukee drill is rated at 400 low speed, 1500 high speed but I don't know if these speeds are under load. My question is do I use the low or high speed setting?

Re: Drill speed for flex hone?
 

I'd use the low speed. If you use high, you're gonna feel like you're churning butter the old fashion way!

Re: Drill speed for flex hone?
 

The lowest speed the drill will run, regardless of ratings or settings.

Okay, low speed it is, thank you.

How does this look, haven't washed the cylinder with warm soapy water yet?

Lookin like a pro job from here. After the final clean give it a wipe with oil to preserve it until assembly.

Also depends on the lube used .........slow speed with marvel is usually pretty good.....

Going to give it a bath and then wipe it down with oil and wait for the rings to get here. Thanks for the help guys.

Carry on and keep smiling it was quite easy wasn't it.

What is the latest update on your repair?

Got sidetracked with minor issues on the '36 and about to button that up in a few more days. Got the Hastings rings from my machinist. Looks like the gaps on the rings will be about .015, little larger than ideal but should be okay?

Re: Drill speed for flex hone?
 

Looks like you're getting it done - nice work! The ring gap of .015 will be just fine - just take a file to break the sharp corner/edge on both sides of the gap (keeps them from scratching the bore). You only need to just barely take the corner off - don't file away on it!

Re: Drill speed for flex hone?
 

Things are good remember the ring gaps are stated as minimum gaps not max .015" will be great as already stated. How did your glaze break and cleanup turn out or need I ask? :)
Good to see another fine home grown project move along.

Will carefully file corner/edge on the rings.
Should be able to get to this in the next day or two.
Appreciate the help and encouragement.

Just use some 320 paper on a flat file to do the job but it really isn't required if you didn't file fit the rings.
