Pics would be great.

I would pay $500 for a good square file guide/vise combo if you are listening homelite410 :)

LOL...I dunno there...you could buy a hell of a Oregon bench sharpener for that and just take extra sharpened loops to the woods.:rolleyes: For me, it would be $100-$200 and it better dance at that price.

Only new option for square grinder is 1K and a bar mount file guide is $200 (no vise).
 
So $1,200 to set-up for chisel chain?:eek:
Bailey's told me their $400+ Oregon bench grinder can do square chisel. I have zero experience with a machine. I'm not paying a shop to sharpen my chains and I think for $200 we should be able to come up with a hand jig for square chisel....based on the G-107. Maybe I should just buy a G-106B and take it down to a machinist to adapt....I know what it has to do based on the G-107. :confused:

You can buy grinders for that. I bought 2 silvey RS II for $560. Free hand is a lot cheaper and the atop is available right now.

I'm sure Mike could make your parts if he had the guide to see what he needs to make.
 
I am yet to see a used Silvey for sale. If you have a line on one, I would appreciate the contact info.

As far as I know, a $1K Simington is the only option for a current production square grinder.

An ATOP with a Homelite410 vise is over $300 and the angles are fixed. For a low volume person like myself, I would gladly spend $500 on a square file guide/vise combo that would allow me to play around with the angles, control cutter length, and file depth gauges. I am only after the result and shop space is limited for me so a file guide that can be used with a bench vise is much preferred over a grinder that takes up bench/floor space.

Just FYI, I am not able to see any of the pictures posted in this tread.

Uhhh...I don't know how to make the pic thing possible for you....I inserted them into the post. Can anyone else not see them? If we were able to make a 'fortified' G-107...I think you would be very happy with it...I have made it work for 40 yrs and I know its faults.

Granberg 106a (un-ported) 22 L file bushing for stihl 6 sided

Guide rod to steel bushing fit in guide turret weren't snug from get go, and with use the rod gets the wobbles. So, maintaining tight angles (any of the 3) but esp the corner, becomes trying. This rod mics 0.047 at ends and 0.043 to 0.045 in the middle 3/4 of length which is stroke wear. Drill rod from msc (or some nice S2), is easy replacement for guide rod. Bushing in the turret could be replaced and reamed to fit new rod for better fit. Lithium grease bushings seems to help for smooth cuts.

JB weld in the file end bushings to pot them, if you like to sock down the thumb screws. These aren't potted and work good with easy strokes.

Not all file sides are Flat. even from same box. got to take that in account in a guide. just sayin.

Think @madhatte might a had some pics of a guide set up for square. Their probly gone now but maybe he'll see this and still have them stashed away and can upload them. pie.

Just some stuff that might be useful, ime.

Crofter, Art Martin, Gypo and bunch of those guys really knew alot. alot
 
Yeah, agree on the rod....went down to find a tighter rod at the hardware store. I could feel uneveness in the galv rod and the uncoated rod...worse on the galv. Have to find some nice drill rod like you say. I'm not sure I understand the rest....so you're taking a stock G-106A and making it work for chisel? Never used a six sided file...always used the PFERD. Love to see all this come together for a product jig anyone can make.

A slight derailment but grinders have been mentioned too. There are cheapo grinders that work at a right angle to most that have been beefed up to work well, probably a clone of a quality grinder somewhere. Not sure which grinder to start with or any of the zillion and one tools that will spin a small wheel. The way I saw a square ground tooth sharpened it looked like a stationary wheel would work.

Linear bearings are always on e-bay cheaper than dirt for the small sizes needed.

A replacement nose sprocket assembly might be another handy item or just the tip of a cheap or damaged bar.

Seems to me that a square grinder could probably be kludged together for a few hundred dollars or less. If I still had my mill and lathe I'd take on the task. Might be enough people that want to play with one that peddling them for under five hundred would be profitable once a design was ironed out too. I have two square ground chains on order now and I plan to file them using my Granberg and a goofy file. The Granberg adjusted right does hold a tooth in place nicely and I'll flip the top out of the way to file. I found myself with three Granbergs so I may cut on one later to try to square file with after I figure out what I need.

If people want to chase after the grinder idea we might start a new thread.

Yeah, I'm only in this to make a decent hand jig again...like the old G-107. I'm not trying to reinvent the wheel here, as it's been already done. The trouble is working with a machinist online...have to send my old G-107 to a stranger and then I have no jig for anything I do here. And the 'stranger' may be busy with a hundred other projects and my jig just sits there for months. You see where I'm going with this. I can take my jig to a small parts machinist locally and solve all the original issues and maybe even make a new one from a G-106A/B(don't know which one resembles the G-107 best). At 60, I don't wanna learn to free-hand a chisel file and I'm not ready to jump ship into a $500+ bench grinder. For me, the answer has always been the Granberg jig and I would like to continue in that same vein.

So thinking along those lines, what is the feature and physical difference between the G-106A and the G106B....or is it just that the G-106B is Granberg's latest variant?

A few photos survived 'the troubles' in this thread:

http://www.arboristsite.com/community/threads/the-oregon-file-guide-modded-for-square-filing.69509/

My favorite was a a pair of simple replacement frames cut from aluminum bar stock, to replace the cast ones supplied with the Oregon and Granberg units. This was BobL's version. I will try to sketch it from memory:

The small round and square holes are for the existing guide bars. The larger, round hole was for a barrel shaped piece at each end that had a slot to hold the flat file (shown from the side and from the end). Holes for set screws were drilled and tapped where shown by the arrows.

Homelite410 could knock these out for us! (Hint, Hint!)
