Have ordered x20 of these bars - further pics and info hopefully from Tommy Craggs (Treecarver Tommy on here) who is the only person in the UK to have one... pretty unique bar based on the 1/4" .043 chain by Stihl.
Pre order offer - you will get x2 free chains if you order before the 7th Feb - this to help mitigate the £95-00+vat of each bar....
Carving bars - put in MS150 to bring the bar up.
You can use on other saws as it has a universal mount but wants to be under 30cc - too much power will cause the bar tip to fail prematurely.
This is the smallest nose chainsaw bar in the world - R6 (radius 6mm). Smallest dime tips are R9.
Note - this is for experienced carvers as this bar is for finishing detail and very fine work with a chainsaw. It will not stand up to heavy duty use and blocking large areas out. You should already have another carving bar and saw set up for this.
There will be Sugihara bars in 4 months for the MS150 with an R9 tip which will be stronger for more general use.
Notes from the manufacturuer:
'The bar is laminate style (3 pieces, not solid one piece)
The reason is that the bar tip is so small that it is very hard to carve our the inner rail particularly around bar tip area. So we decided to employ 3 pieces process, which makes us easier to shape the precise inner plate.
This is not a heavily used carving bar, so we decided to trade off some of the bar strength.
Instead, the bar is much lighter than normal solid 9", 11"bars, by applying lightning holes to inner plate.
We have added extra welding process to the inner bar tip area to retain strength against the tip split opening.
The Stelite is molded on to the bar tip, and it is slightly softer than our other bars and many of other brands' bar tips. Also, the bar tip is individually grounded and shaped by hands.
Being so small, we are more concerned about cracking. (The harder, the more chance of cracking) We are aware that some carvers prefer much harder bartips, but we needed to make sure the balance is good.
The whole logo, by the way, is laser engraved instead of printing, so will stay almost permanently.
We have been selling specialty carving bars over the past 10 years, started from 9R carving bars almost first in the market.
From that success, we started 7R carving bar about 6 years ago. This was a challenge for us to persuade our contracted manufacture and test the market, since it was the smallest possible radius for Oregon 1/4 saw chain, but turned out that many carvers were very happy to add it to the line of bars they use.
The 6R started obviously when we saw Stihl's making new carving saw chain, so it has only been a year or so. So far, over here in Japan, people are happy with the performance.
Hayashi Takao is our partnered carver, and he has been using the bar at many occasions including US carving events, since we produced the prototype.
He said the bar is extremely useful for detail work of course, but also recommended not to use it for too much bulk cutting work. '
