Oregon 720-120 automatic chain grinder

[fordf150]

affordable....$7k is much easier to swallow than 20k.

cant speak to any differences, never been around a franzen and honestly i did almost zero research on the oregon grinder...affordable option for an automatic grinder that will save me time....since I am now a one man show it was a no brainer to try something

I have two quick questions.

1) how long would you estimate it takes to pay off said machine before it starts making you money?

2) is there any way to adjust how much material is taken off each tooth? Seems like someone who just needs a “touch up” but doesn’t hand file won’t need as much grinding as someone who has a very dull, rocked chain. Does the machine auto compensate somehow, or do you just set it and forget it?
If the latter, how many grind jobs can you run on a chain before the chain is kaput and there’s nothing left to the cutters?

Why didn't that stupid grinder sharpen the other tooth opposite to the one it did sharpen?

After all it is a loop that can be used in revers as well, isn't it?!

I'd like the grinder more if it wouldn't just force down into the tooth but rather lower the wheel slower.

Looking good though, now I know whom to send my rocked loops for a sharpening!

Congratulations on Your new shop tool.

I watched the whole thing, cool grinder.

$7k/5=1400 chains to break even if you just figure what the grinder brings in but the ability to do other things while it grinds chains makes it a little more difficult to figure out at what point you break even and start making money.

its adjustable jsut like a regular grinder....take as much or as little as you like

I always thought that if I bought one, I would put it in the front of the shop to draw people in as an attraction. Put on some coffee and put out some popcorn. Upsell them while they watch.

Plus, some people will believe that a "computer sharpened" chain will cut 'better'. So some of the cost could be considered promotional.

Did I read that right, that you are charging 5 bucks a chain to sharpen?

Last I looked it was $12 and up at my local Stihlership.

local hardware store charges $4, amish charges $2, the other local saw shop is $5. 20 miles away in the "rich" area it's only $8.

on the old 511a i can do the average chain in 6 minutes, to make my hourly labor rate that works out to $5 a chain. plus its kinda hard to charge much more than that with my chain prices

I heard some Amish guy, "Angelo" in Jersey does make a fair living at sharpening chains at $2 a loop.

Them Amish boys are hard to compete with

got a video showing the 3 stage grinding but its not a very good one, didnt think of making a video until it was clear around and going over the last 5-6 cutters that i had set it up on. uploading it to youtube now so I'll post it when its done

 

[fordf150]

made another round after this one to do a final touch up and take that last little bit off to get it sharp.

The difference between Franzen and Oregon.
The Franzen detects the tooth side.
Oregon will switch dumb between left and right tooth.

So true. If sharpening a well maintained chain you can zip through it in 3-6 minutes for a 12"-18" full comp chain. But a chain that needs depth gauges, gullets & maybe 2 passes as it more than just blunt can double or triple that time. I wonder how the auto grinder deals with semi skip chain or chains that have 2 left hand cutters in a row. I think the savings will be made by being able to do something else while a chain is being ground.

No Problem with the Franzen auto-grinder.
I do about 50-150 chains a day with it and the franzen runs fine with the watercooling.
