Oregon 511A , 511AX VS Stihl USG

The 511ax slides in and out and has tilt

 

This is on the 3rd design of the 511AX. The two earlier 511AX designs just tilted.

The new Oregon 520-120 grinder also both tilts or slides

 

Thats is a easy choice 550 Euro equals 596.90 US Dollar and 400 Euro equals 434.11 US Dollar. For that little of difference in price I would USG.


My 1st choice was the Silvey grinder but settled for 2nd choice USG.

 

Finaly i order the USG looks to my eyes more acuracy more pro and more durable , with a little more pressing the final price go to 500 , i think its good deal , have it in my hands after 20 days . photos when it come

 

What is this "10º" spec you all are talking about? I know where the 30 & 60 are applied. Thanks in advance.

 

"Offset 10 degree tilting vise for correct corner (or leading edge) angles on chisel cutters"

 

I disagree,

These aren't easy to find NIB anymore.



The rest:



However as has been said, operator technique is the most important thing.

 

A nice thing about a Silvey 510 is most of the parts are simple enough that a local machinist could make anything that you could not get at the hardware store.

I rebuilt my early Silvey swing arm grinder with all new fasteners and bearings. The fasteners were from the hardware and the bearings were from the bearing store in town.

I'm perfectly content with my Oregon 511A round grinder. The fact that I have it instead of a Silvey 510 or USG was a situation of opportunity and convenience .

 

I didn't have time this morning for my two cents on this. Actually all the grinders do a fair job of turning a grinding wheel. The big difference is in the quality of the vice. The Tecomec clones all grip the chain in a single point below the cutter via a rail that holds the chain. (the chain moves when the clamp is engaged) The next step is the 511AX type. They grip the chain in over a longer area but again below the cutter and the chain moves when the clamp is engaged. Better but the design has some plastic parts that are prone to wear since the environment is abrasive.

The Silvey has a pawl that forces the cutter down into the rail since you pull backwards into the chain to seat it thus immobilizing the cutter and the wheel can be ground into the corner further anchoring the chain. (the motor is bidirectional). The sad thing is the Silvey design is so much better and simpler. I don't know if there is a patent, but it would be great to copy the design if it isn't. The Silvey wheels are much larger and don't seem to generate the heat like the smaller ones do either.

I haven't used the USG and don't know much about it. I was just pimping you MasterMech.

As said earlier, the operator is the biggest variable.
