.... it has been ages since I have done this ...and the last time I did-it ...it was a PITA with the one I had(it was red in-color). That was lost-in-the-move ..... so I beeez needin' one ...

I have 3 motors to do within the next 45 days or so ..... I don't think that an electric one is in-the-budget .... but if it is a time-saver and more accurate - maybe I can see that through...

Give me your

i use the cheapest Summit one you can buy.

In fact--i will sell mine. Used on one set of rings.

I use this due to I dont build engines for a living

Although I do have the Proform electric filler, I really don't recomend it. Now I wish I would have bought the hi-dollar one from Goodson.

The one that Mr P body shows from summit is the best bang for the buck. I have one and have used it on countless motors including for my racing hemis which use tool steel rings.

Chuck it in the vice and only file on one side of the ring and debur when your done.

A reg hand file will work too, chucked in the vise.

I just us a small fine file in a small vice doing one side using the top of the vice jaws as a guide and take your time.

THX guys ...

So C1 ... you feel that the electric one is tooo aggressive ?

And then on the other end of the scale is the hand-file in a vise ?? ...

A WIDE-RANGE of opinions here .....

COOL ...

We sell a tool for that: hand-operated, lifetime guarantee on its diamond grinding disk. www.area51groupllc.com, also on Ebay as seller topside340. We sell 'em to Summit & Jeg's.
We also have valve spring testers, height mics, leakdown testers, oil filter cutters, rod-bolt stretch indicators, and rearend setup tools.

imho this is the best tool for the money ring filer

Simple, and the results are pretty good

Ken -
No, our mics are not Chinese. We do them here.

I have used the Speed Pro hand operated ring filer(like the Summit one) for years, and then I bought the Proform electric filer I have messed up several moly rings by not taking my time to make sure they where cut square Once I got the hang of it it is way better Don't forget the top moly ring is way harder than the second cast iron ring found in most H.P. file to fit ring sets, the second ring needs a lot less time against the grinding wheel The electric ring filer makes the time seem as twicre to three times faster than using the hand crank Speed Pro filer and nine times faster than usig a file

I have this cheap pro-form one:

It works fine and cuts fairly quick. It's what I have, and I have not compared it to the other types which may be better?

I prefer to just take a chisel and just pinch off the ring until it will fit in the bore. Who gives a crap about gap. Then grind nothes in the top ring for gas ports.

Just kidding.........

I have a hand crank one. Problem was the hard rings I was forced to run in my ole nitrous motor eat the wheel up. Plus the ring was 4.255" and I was cutting for a .040" gap in a 4.245" bore. Found a cut off wheel to get it close then file to perfection.

I have noticed people really concerned about how square the cut is and even throughing rings they screwed up away. But, will stick a ring they didn't debur in a new piston and trash the ring groove.

Hint... It is more important how well the top ring seals against the bottom of the groove and second seals against the top of it's groove than how perfect you gap the ring. Have seen some hard core guys order the piston with grooves .0005 narrower and then sand the ring's surface down for the desired fit. This idea was around long before the diamond finish deal from Total Seal.
