  1. As for power/weight ratio Husqvarnas 'new' 455 weighs 100g less and produces .2kW more than the older generation Echo CS-450, that hardly elevates the 455 above what you class as the 'pathetic' power/weight ratio of the CS-450. You need to change your signature from 'Information Collector' to 'Misinformation Collector.
  2. I don't buy them for their power to weight ratio, I buy them as they spend more time working than they do sat in the dealers awaiting yet another ignition re-map. Weight brings durability, if they're too heavy for you have an extra egg for breakfast or man up.
  3. The 450 has a better air filter than the 501 and probably the 390, pleated paper/gauze type rather than a fine mesh, twin ring piston would be my preference, not sure what the 501 has but it'll probably be the same as the 390. Serious question, if cost and weight aren't an issue and the power is the same where do you see the benefit of the 390 over the 450?
  4. You can't really make a bad choice whichever you go for.
  5. The 450 is long and low even compared to the 501 which is similar in shape to the 390. The 390 has the same power output as the 450 but is lighter and cheaper, your choice may come down to what you make of that.
  6. I use an Oregon spout, it will fit the 450, never tried Stihl or Husky spouts so can't comment.
  7. Just found out that the CS-501SX actually comes with a .325 .058 chain, it was incorrectly listed as 3/8 .058 on the website of the dealer I bought it from. Checked the manual and it's definitely .325 which is pretty annoying as I have already bought a 20" Sugihara bar and chain for it.
  8. I've heard the 1/3 of cc rule of thumb but not sure if it really applies anymore as most saws are producing more power at a given engine capacity than they were 10, 20 etc years ago. Thinking about the relationship between cc and power, I feel that small saws putting out the same power as bigger saws are high revving so they'll run a short bar fast but don't have the torque of the bigger engine which is probably slower revving and making the same power but with more torque. Hence the the 390 and 450 both have the same maximum power but the 450 is spec'd to run a longer bar than the 390.
  9. Sorry That is my honest opinion though, really if at all possible visit an Echo dealer and get a hands on even if you end up buying from your local dealer. To be fair though I think what puts me off the 501 to a degree is that unlike the 450 on an 18" bar the 501 doesn't feel balanced on a 20" 3/8 bar, actually wondering about the possibility of running .325 on the 501 and using the bar off the 450, the 450 can go back to the original 15" - 16" bar.
  10. And now I'm faced the the difficulty of deciding which saw to use on the day, when I only had one it was simple
  11. Ok if you haven't decided yet here's my opinion based on just receiving my new CS-501 today. The 450 feels more robust IMO than the 501, the 501 apart from being lighter just doesn't feel as durable. I'd put durability/longevity 1st before lightweight so for that reason given the power output of the 390 and 450 are the same I'd definitely............ ......go for the 450.
  12. I've just bought a CS-501, funny but I never considered a CS-550, agre with what others have said the likes of the 390 and I guess the 501 are newer generation saws, my only slight concern is that the 450/550 etc may be that bit more durable but thats just a feeling TBH.
  13. Looking forward to seeing the Mac up and running, I'd like to get my hands on a 10-10,
  14. To be honest how quickly it cuts compared to other saws doesn't really concern me, it was cutting full of the bar in Beech last week, slowly? yes but I'm not racing so it'll do for me. It was my only saw up until a fortnight ago so it was a case of using what I had although it's now accompanied by a CS-8002 on a 24"/28" and a soon to arrive CS-501 that'll be on a 18"/20".
  15. I have the CS-450 and can't fault it, it's been on an 18" bar (Sugihara solid from Rob above) since I got it. Past couple of weeks it's been used (not felling) on Beech and Sycamore, diameter almost 2 x bar length. It can slow a bit on the 18" at full depth but it'll get there in it's own time. For felling up to 12" you'd only need the standard 15" bar so it'll sail through. IMO a great saw, easy to start hot or cold but it took a few tanks of fuel to run in properly. I can't comment on the CS-390 but regarding the chain size according to the Echo (and Forest & Arb) website it's actually 325 .050. Strangely the 390 bar options according to the Echo site are 33 and 38cm, the 450 is 38 and 45cm, the power may be the same but maybe the 450 has more torque?
  16. According to HSE it is within the regulations to use a climbing helmet if it's rated to EN12492 which the Petzl Vertex Vent is (what the Stihl Vent Plus appears to be in reality) Chainsaw personal protective equipment (PPE)
  17. never mind the cost, someone has to pack it away
  18. Very good point, a bit more info below. [ame=https://www.youtube.com/watch?v=3-q9yxyS4BM]X Rigging Rings[/ame]
  19. This is what I would go for based on what you've already mentioned. You could no doubt shop around for the best price on the individual components. You could replace the RC Top/Mounting strap with something much cheaper as it isn't load bearing, it only holds the lowering device upright. See video for the reason why you may want to do that and also why I suggest the RC1000. [ame=https://www.youtube.com/watch?v=oZ9UzjBw3GM]]See Here[/ame] You'll still probably need a few slings and carabiners. Hope this is of some help.
  20. Don't doubt what it can handle but, you know 16mm rigging rope and large Portawrap do tend to suggest an impact block, to me anyway
  21. To be fair he had mentioned a 16mm rigging rope and a large Portawrap
  22. Wouldn't you just love to take them and dump them in their (the councils) car park and tell them it's now their problem. If only:sad:
  23. No, that's the point, easier to ask for a steel carabiner to be sent up rather than asking for a rigging carabiner to be sent up and then have to explain the difference.
  24. Agree on the steel carabiners although I did get 2 x steel boa locksafe in addition to the steel screwgates, regarding the slings again similar but DMM in a variety of lengths. As far as a means of attaching the impact block & lowering device I think initially the op mentioned a dead eye sling but you're right, for attachment he'll need either 2 x dead eyes, 2 x whoopies or any combination thereof. I personally use 16mm (one dead eye and one whoopie) with 12mm Sirius Rigging rope. The FR Jones kit linked to previously looks like a nice set-up.
