tl;dr:
#1 - For doing my 1st top-end rebuild, do I need anything beyond a 54mm ring-compressor?
#2 - Do I need other stuff if I plan to do >1 top-end rebuild? I've gotten the proper Klein t27 t-handle, have calipers & porting gear, but no specialty stuff I can think of...want to order now, as my current kit-660 has a bad piston, and shortly I'll receive both a new piston for that one, and a whole new blue g660 (as a 2nd unit, I want/need 2 if it's to be for job use as well!)
~~~~~~~~~~~~~~~~~~~~~~
So, luck wasn't on my side when my piston got chewed-up on my new kit-660, but it doesn't really bother me because the unit (besides it's top-end...I think!) is just chock-full of OEM greatness on all the important stuff (and more), new walbro carb etc etc., at any rate though I'm pretty sure the cylinder is gone and piston is definitely destroyed.
I'm posting to ask Re replacing the top-end, whether or not (probably NOT) I can refinish&salvage the cylinder, no matter what I need to do my 1st ever removal ./ install of a piston
(I ported my 590 successfully so am not an utter noob, but I am at the flywheel, the bottom end and the piston!)
What gear should I buy if I'm going to have 2 of these saws, and intend to do multiple top-end projects or ports/rebuilds?
I know: Ring Compressor (54mm)... that's it!! I have digital calipers, have everything for porting and have every 'regular' tool (hand tools &power tools) any homeowner would have in a 'solid garage', EXCEPT a proper vice.... I want to order any&everything I need, NOW, because I have a blue G660 pre-assembled china660 en-route right now, and w/ @Ronie generously offering to send me a piston, it's a mailing-race between which project is first:
#1 -- My work-saw, initially built on the blue bottom-end but w/ all the OEM / walbro /etc swapped-over to it,and
#2 -- My "play saw", which will get a piston (maybe P&C) swap right off the bat, but subsequently be a "mostly-Blue Thunder" unit that I'm going to port & 'push'
My thinking there & being I'll break saw #2 here&there but unit #1 should be quite reliable and, when unit 1 goes down, my work w/ #2 - and the on-hand nature of it being a parts-saw as well - means I can do immediate, in-house repairs to unit #1, using aftermarket parts, until OEM is delivered and saw #1 gets yet-another OEM upgrade!
Only recently got the CS-590, love it but quickly found I NEED to have 2 comparably powerful saws, if I'm going to use 1 of them to begin something like, say, cutting a felling notch (otherwise how do you cut-out a stuck bar, or finish your back-cut if the saw died, if no backups on-hand?) The 590's great, but the 660 is just a blast, feel so lucky I could "get into this platform" w/o selling an organ ;D
[For fun & posterity, as I plan to just keep all my 660-related stuff to this thread for tidy-ness, so here's the video I got of it running in its most-recent / current form, right before realizing chipped piston, thing was still eating wood!! I put a couple other vids up of it under same account, should've started this years ago it's so easy to get so much into a video!
