Post up your ported cylinder Artwork

Porting game so strong....
You run into clutch issues.....

I did before some friends helped me with my chains.

Those high output 1/5 scale rc car engines are cnc ported. At least from the most prominent porter in the business. OBR. They have multiple dynos and a flow benches. 12 hp from a case reed 47 cc engine on pump gas is one of their offerings.

id love to see the tooling and setup involved. im sure you could figure out the intake and exhaust on "most" saws, but i cant see something getting in closed transfer ports.

although i guess a lot of cylinders have transfer port covers these days.

This is their 34cc reed engine I'm upgrading my buggy to down the road.

FFS, he drives like my ex-wife.

im not a machinist, but i cant really picture a way to do anything meaningful to a chainsaw cylinder via cnc. it would certainly be cool for repeatability but just cant see the tooling aspect being workable.

I’d say it’s highly possible.

I can't imagine the hours to design and program that helmet let alone design and build the machine and software.

They could have just 3D printed it. Imagine the cylinders you could 3D print.

I’m willing to bet the 2511 jug is cast from a 3D printed mold. Probably lots of others.

I just wonder why Echo likes using transfer tunnel inserts.

I just wonder why Echo likes using transfer tunnel inserts.

From manufacturing standpoint of view, its easy and cost effective to use insert then to cast something and create a tight space. I think, ejector pin that comes out the mould will be too narrow and thin thus might risk getting broken or damaged

Wow, nice work there Mike, can't wait to see the video of that running!

Looking forward to putting it in the pine and poplar around here. Thanks mike

2159, could polish the exhaust more but I think it will work

Looks good!

036/044 hybrid cylinder
I didn't do to much to it, just widened the exhaust, squared up the intake, took some off the piston skirts and trimmed up the fins so the top cover would fit. Timing numbers ended up being, EX 109, TR 128 and IN 76. I'm surprised that the exhaust is so low, anyone know what the stock slant fin 044 timing numbers are?

Just curious, and if you don't have it don't bother, but what does the case side look like at the lowers?
