I think my MS460 54mm build might have a similar power, but it certainly have twice the fuel consumption.

Looks like a strong runner! I'm a big fan of the 1128 series Stihls. I've got a couple of 044s, one is a big bore, the other is a hybrid. The big bore is a pretty "pipey" build...I was using it as my main falling saw for awhile last year, as long as I was cognizant of keeping the chain speed up, it ripped. The hybrid I did a tapered piston and squish band...it ended being a lot torquier than most of the other 044/46 hybrids. I'm going to try some more stuff on it using a 064 piston and possibly doing finger or bridged ports.

I don't have a 460/046, or I might be trying something with a BB cylinder...maybe a 660 piston to open up the opportunities for different timing numbers? I've already got a plan for a 500i, involving a 660 piston, once I get some time on my hands.

Converting the already destratoed xtorque 372 to a 52mm OE-style farmertec cylinder, it's going to see some port/machine work of course. This particular FT cylinder is pretty rough...luckily the plating/hone looks good, so I can fix the rest.

On my bench right now are a few old Homelite XL and Super 2 saws. I probably have enough spare parts to make two running ones out of the mess. I have one together so far..

 

[Sierra_rider]

I'm going to say that I'm tentatively done with the 372 cylinder. It took ungodly amounts of machining to get where I wanted for numbers. Now I'm just hoping that the exhaust and intake actually bolt up with how much lower the cylinder is sitting.


Red line showing how much I cut out of the lowers:

Got a couple husky’s on the bench. 61 has a jonsered 630 top end, HS224 carb, and non-baffled muffler. 266SE has a 268XP top end, HS260 carb, and non-baffled muffler. Got a little more work to do but they’re coming along nicely.

 

[ballisticdoughnut]

Both saws are now ready to cut. 266/268XP is kind of a ugly duckling right now (until i find a nicer top cover) but it’s all good under the hood. 61/630 is sporting a jonsered 630 top cover, sticking with the orange and black color scheme. Gonna get into some wood here soon.

Nice work. I’ve got a couple jonsered 625/670s im cobbling together night now.

Nice. I came upon a couple 630 cylinders recently so I figured I’d use one on the 61 I picked up not long ago. Is the 670 similar to the 266? 630 is 48mm bore, I’m thinking the 670 must be 50mm?

Yeah, I believe it is very similar to the 266, 50mm bore. I was going to build it with a 272 top end but decided to stick with the 670 top end on my 625 cases.

I'm attempting to do bad things to my 500i...it's going to be a bit of a project, but this will be cool if I can pull it off:

Hyway for mockup, I'll do the same with OEM if I like the results:

I still need to figure out why this saw won’t stay running, but I started building a better muller port for my ported MS361

 

[Lawless]

My “Stump Saw” getting some love. CS6700 that has never failed to run and gets abused and pushed aside like a rented mule. New clutch bearing is on the way. I found a replacement for the broken finger adjustable idle screw, new brake handle/cover and all the parts to convert to side chain adjustment.

I’ll clean it up, dress the bar and see if I can get the chain in some semblance of sharp. To be from the 90s she’s a tough broad.

I’m sorry baby….I’ll treat you better….can you make me a sandwich….

The 500i is back together and running with its new piston...I don't know what to call this saw, the Franken500i, the 566i, maybe just a hybrid 500i?

I put a 660 piston in it...the 660 piston is the same bore diameter, but a much taller piston. It allows for the squish band to be cut for increased compression, while giving you almost unlimited options for when the intake opens up. The stock 500i intake port is quite low and I wouldn't want to add even another degree of duration, so you're limited with the stock piston unless you don't mind epoxying the floor of the intake.

I won't go into the details of what exactly it takes to fit a 660 piston in a 500i, but it's a lot of machining and grinding on both the cases and piston. This really isn't a feasible mod unless you have a lathe and a milling machine, or at least a vertical mill table for the lathe.

I only started it up, but really haven't cut with it. The one noticeable thing is it's quite a bit more responsive...not like the stock 500i wasn't, but this is peppy...after all the work is done, the 660 piston is 10 grams lighter than the 500i piston. I left some room on my intake, so I might be tearing it apart again to add a bit of duration.

Nothing to exotic about the porting on it, just sticking to what I know:

...and in anticipation of doing the Franken500i, I built this vertical milling table for my lathe last week:

 

[Sierra_rider]

I got to run the hybrid 500i out for a little bit today, I'm impressed. It's a monster, really snappy, revs like crazy, yet still has decent pull. I might take it apart again and drop the cylinder some more...where my numbers are ATM, I could drop the cylinder a couple degrees and pick up even more torque. As it stands right now, I feel like I picked up considerable gains over stock.

Thanks for posting the milling attachment you made. Just what I was looking for. Where did you get the cross slide table and what brand?

It was a random one I got off of Ebay, cheap chinese crap. It's graduated in metric and not the smoothest operating slide...so I have to do a little bit of math. I wouldn't recommend it, but it does work if you're on a budget...I might make another one in the future.

Here's the link, it's gone up in price...it was $75 just a couple weeks ago:

Made it out there but could only stay a short while before I was absolutely finished. Looks good and sparkly.

 

[Juniors saw works]

562xp
smoothed and polished transfers
LRB pop up piston
.14 base gasket
And what a project the muffler was but it sounds great I don’t think I’ll do that again the last one I did I only cut inside the baffle on the underside and cut out what I could this one is completely emptied I can’t attach the video of the cylinder when it was finally done but that was at the start
