Saw for blocking? Small bar on large powerhead?

Hello all,

First time poster here. Looking for advice on a saw setup for blocking out.

Ive been carving for a little while now. I use Stihl 170s with carving bars for the detail and mostly a Stihl 290 for blocking. The 170s are under powered for any real blocking out. The 290 has an 18" bar with 325 pitch and 50 gauge bar but this can be a very slow cut. Especially rip cuts the length of the log.  I want to get a large powerhead and put a 3/8 pitch chain (or 1/4 ") with 43 gauge bar on it. This should have lots of power and cut quickly with a thin gauge bar and chain.

Does anyone else do this? Any Stihl saw recommendations? Any safety concerns?

Thanks
Dave

For some reason I cant edit my original post. The current gauge on my 290 is .063. I want to take it down to 043. with 3/8 pitch chain. Same as on the MS170.

You should research if a 3/8 Picco clutch will fit to a 290 if it fits original or aftermarket then you must search for a suitable low radius nose bar that will bolt onto a 290..If you can get the clutch you can bolt a toonie tip bar also and run 3/8 Picco chain.I don't think any problems will occur as long as the clutch fits and bar bolts on properly..

So my research and emails with some very knowledgeable people suggests that I should get a Stihl 260 Pro with 3/8" lo pro, narrow kerf chain, and an 18" toonie bar. The only problem I see is that I dont know if 3/8" lo pro chain can handle the 54cc motor of a 260.

Any opinions?

I dont own a a 260 pro i was about to buy one but I went for a husqvarna 321e electric for neighbourhood reasons altough i still keep my only saw the 170 with 12" cannon bar and readily carve with it.I handled the 260 pro many times in the shop and its a lightweight nice machine an analog machine also which means it doesn't possibly benefit from low emission thing if it matters to you and the new generation is no lighter i guess.I don't how big is your wood to block but if it doesnt require 18" it's better to bolt a 16" from my perspective.As much as I know the 260 is a mild saw its not on the wild side i think 18" solid tip bar with 3/8 lp chain might even be a little much for the saw..
