RE: Custom Piston Rings
 
The Chinese rings tend to be hard and take a good while to break in, but many, many people are using the DLE engines with the stock rings without problems. You could always use the engines you have as they are, and then change them over to Bowman rings at some time in the future.

I too am a big fan of Bowman rings, but they are not absolutely necessary if you can't afford them at this time.

Thanks for the reply AV8TOR.

I was kind of hoping that was the case. I just wanted to make sure before making a decision.

Just can't seem to be happy if my engine is not running on a Bowman ring :)

Anyone know if Frank is still doing rings? I've emailed him but haven't received a response... [:o] Need a ring for a Webra 1.20 if anyone knows of any other source.

Hello Phil, I'm still making rings and do have the Webra 1.20 Dykes rings. Email me at [email protected]

Thanks Frank, email sent!

My friend has 2 Webra 1.20 engines. From brand new one would hand start. The other engine needed to be started with a electric starter. I replaced the stock ring with a Ring from Frank Bowman...and it hand started first try. It had much more compression and ran great. Best rings on the planet for our RC engines.

I'm already a believer John. I've repaired my friends Webra with new bearings and Frank's ring. Runs awesome!

Hand starts easily, always has...

Hey Capt,n,

I just spoke with Frank and he has rings for the M22 plus others, so I'm just waiting for TDA to hopefully give the green light for me to take the plunge.

That sounds good too me and I am sure Franks rings will be kind to the plating and not wear on it! Capt,n

I just read in another forum, a guy installed a Frank B. piston ring in a Mintor 22cc engine and gained over a 1000 RPM. Capt,n http://www.rcuniverse.com/forum/js/f.../thumbs_up.gif

Send your piston and cylinder to Frank and he will make you a custom one.


captinjohn 12-17-2012 06:13 PM

RE: Custom Piston Rings
 
Just email Frank. Some engines have the same bore size...a metric size and a lot of rings are the same width. He may have one already. He may need to make sure if the ring is pinned &amp; provide for that. Capt,n

Hello, and greeting from Middle Tennessee. I would be very interested in trying some of Franks rings in the chainsaw engines I build.

You may need to email Frank. He may be too busy to read all the postings. His email is in a previous posting. Capt,n

Well I went fishing for steelhead trout on my birthday and got no bites even. I just cannot seem to catch one on my birthday. I guess I will go flying instead!

Most piston rings price for Gase engines are $10 ea.

I have been a machinest all my working life and making Custon Piston Rings for approx. 12+ years for Gas, Glow and diesel engines, some motorcycles too. With my custom rings, performance will improve over nearly all factory rings because of the material I use, machining method I use and Ring gap I recomend with my rings. I use fine grained cast iron machined from solid round bar stock rough cut on OD to .010 oversized and finished with a .002 finish cut on OD for accuracy. OD of ring is cylinder bore to assure ring fit is correct and round rather than making ring larger than bore and shinking oversized ring after saw cut into smaller bore. Rings are then hand lapped to .001 smaller than piston ring land. I don't saw cut ring, I have a special tool that snaps ring before heat treat at 850+ degrees F. After heat treating on mandrels I gap ring to .001 to .002 end gap. Rule of thumb in machinest world on cast iron rings is .001 to .0015 ring gap per 1" bore diameter. I make bore gage to .0001 of cylinder bore to gap rings & ship all over the world. I make over 300+ rings and to date made thousands with a lot of happy customers. There is a lot more involved in my manufacturing process along with a lot of tooling involved, too much to discuss here. If I don't currently have dimensions to make rings for certain engines a lot of customers send the piston & cylinder to me to measure for rings & I install rings for no extra charge. I make special rings for 30 CC Homelite & 31 CC Ryobi engines that require a slight mod. of cutting anti rotation pin in ring groove down 1/2 way so my custom rings will overlap pin for much improved performance. Most rings for Gase engines $10 ea. shipped to most countries & US at $14 for 1 & $24 for 2 shipped. Discounts of $1 off per ring on orders of 10 or more mixed sizes & Brands fine. I have been endorsed many times by engine builders like Clarence Lee, Joe Wagner in magazines, etc. Email me if you have additional questions and a list of custom rings that I currently have in stock. Thanks & God Bless all. Frank Bowman at Bowman Rings. Email: [email protected]

I think you should bought another ring.

delfi87 07-05-2019 08:21 AM

But I would be very interested in trying some of Franks rings in the engines I build.

delfi87 07-05-2019 08:22 AM

There are many different piston rings for engine:
