Well I am assuming You are speaking about 3/8 Low Profile like 91 series Oregon? I have no idea about Picco or what ever stihl calls their chain this week? As I mentioned in my sig I have small 7 spline 3/8"-8 and 3/8"-9 that will drive 91 series or equal chain. I have carvers running this setup with hundreds of hours of use. Only problem I see is using a near 7hp Modded PS7900 running a 9 pin rim and a quarter tip carver bar and just punishing the crap out of the low pro chassis chains.

That small spline 8pin,is it a pin type or conventional?
That could be. The Picco rims are slightly (about 1/16" or so) larger outside diameter than the standard rim, and fit better with the low-profile picco chain. A standard rim will drive it, but not as well. I don't know off the top of my head whether the Picco chain and the 91 series match, but I would guess they do. I assume yours are the same outer diameter as the Oregon rims.

Good news! As asked above, are they pin or cast, not that either answer would preclude me buying some.

Not to hi-jack the thread, but I've been meaning to ask about your avatar. Do you race or sponsor that modified?

Yes, the lo-pro/Picco rims need to be a bit larger diameter, to compensate for det different (lower) chassis of those chain.

you can run 3/8" Low Pro in a regular 3/8" drive rim BUT Not able to run regular 3/8" in a rim or spur sprocket designed for 3/8" Low Pro Chain due to the tangs on the drivers bottoming out!!!!!!!!!!!

I assume Your talking Small 7 spline 3/8"? I have Oregon Cast type 7 tooth and these Pin type Steel in 8 or 9 tooth

Scott the milling guys have discussed this matter extensively . The picco/low pro chain will run on a regular 3/8 rim but is not pretty.
I had some custom rims made up specifically for picco to fit my 066 med spline clutch. I use the picco chain for milling as it has a smaller kerf.
P.S. what kind of prices are you looking for your rims and what are the sizes/pitches available? Should just send you a PM about this?

Yes,that correct.Also may get a couple of .325s in the same size
both 7 and 8 which I'm sure you have in a power mate,and a standard 7.
May as well make the shippin worth while.
I'll get with you.

Like I Mentioned in Post 3 running 3/8" Low Pro on higher hp saws will tend to have its way with Low Pro chain...... I have asked Oregon for special chain for carvers with the VX or VXL Cutter on a 72 Chassis instead of the weaker 91 chassis. But if you need a low pro cutter on higher hp saws their will be a
"weak link" that being a chain designed for lower cc saws.

I've been milling with picco on a 066 with bars up to 25" for 13 years now. No problems with the chain, but you need to use the stihl picco spur sprocket that stihl does not make available to dealers in the USA. I run the picco chains on the mill right down until the first cutter breaks off from many sharpenings
Logosol has been using this setup much longer on their CSMs and are a source for the picco stihl rims in the USA.
