Lucas 618 (yet again...)

I grabbed and cropped a better image from the Oregon manual.

Its covered under the "fair use doctrine" since we are using an excerpt for discussion purposes. And I cited that it was from the Oregon manual.

What settings on a chain grinder, correspond to 2) and 3) in this diagram?

 

On a grinder, #2 is set by the angle of the grinder head (on the back).  #3 is set by the width and shape (edges) of the grinding wheel.  #4 is set by the angle of the chain vise, right or left. #5 is also set by the chain vise by loosening the knob underneath and rocking the base forward or back, up to 10 degrees in either direction.

Something else I forgot to mention about the 27RX slabbing chain. Take your rakers down to .050. Otherwise you'll wear your arms out pushing. There are guys who grind them completely off when using the slabber attachment on the big 1030 (30hp) mills. Thats seems a bit excessive to me and may put a bit more stress on everything (but hey, if it works and you have the power, have at it). I run .050 on my 9 chains with the 16 hp engine on the dedicated slabber and have never had an issue.

It bugs the heck out of me knowing there is a Lucas out there that isnt performing as it should.

Me too Logboy, you got pretty much all of this covered, I recall I mentioned something similar about the setup not being level from the pics.

One thing I'd like to add about the saddles binding on the uprights, to stop having any issues I make sure on the end that doesn't have the carriage I wind at least an inch below the desired measurement. Also it pays dividends to clean the upright posts once in a while. I make a point of doing it each twice a year, either rubbing down the uprights with a petrol soaked rag or hitting it with a pressure washer, also once a month I give the uprights, chains and gears a spray with silicone - at the same time I silicone the sideshift winder chain and the rear of the carriage where the white nylon block runs.

Been under a cloud of crud last few weeks, but out in the sun now and back at it
