No, you can use anything that gives a flat first cut. I used a 10 foot long treated 5/4 inch deck board that I screwed down to the center of the length of the log. Once that cut was complete, changed the depth to the desired board thickness and started cutting boards using the freshly cut flat surface as my guide. Repeat as needed.

I'd say "no." I've been using a 2x10 or a 2x6 for my guide surface, and both have worked well.

You need rails to make a level cut. If you have an old aluminum ladder it would make a perfect rail system. I built one with 2x2" and 1x3" rungs. Screwed a couple of 3" screws through the rungs to hold it in place.

The rails are not required when purchasing the saw mill. They are highly recommended in order to get the most accurate and consistent cuts.

Yes, no problem. That's one of the saws I have. Because of the length lost in the mounting, you will only be able to easily cut a 10 inch diameter log with the 14 inch bar, so you are a little limited in the log diameter.

Can it cut with the grian.
I am wanting to put a mantel on top of my fireplace. I have cut a 6 foot section from a tree in my back yard. I am having problems cutting the section square so I can put it on my brackets. Would this allow me to make these cuts with my chainsaw? I know free hand with my chainsaw this is not possible, I always figured this type of cut could only be done at a sawmill. Would this do the job?

99dragon· 9 years ago
If you make the guide surface level/parallel to what you need to cut, it will work fine.
Helpful?
-
Gottlieb· 10 years ago
It worked for me. I bought the guide rails to ensure the first cut is level. I cut the top and bottom, rolled the log and set the guide rails and squared them to the cuts I already made. The end result was four sides square to each other. The guide rails are a little pricey, and I did use a ripping chain on my saw.
Helpful?

BJ01· 11 years ago
Yes, the whole milling system is designed to cut with the grain. The chainsaws have no problem doing it as well, specially if the chain is sharp.
This would be perfect for the job you describe. You would make 2 cuts on one side (top and bottom) so they are parallel. Then you would turn it over and make 2 more cuts.
If you really want an accurate square, then there is another mounting bracket for your saw that allows you to cut 90 degrees to a flat edge. So you would make the first 2 cuts as I described, then use the 90 degree mounting to cut the other 2 sides.

How do you ensure the cut stays level?
-
hfvm· 7 years ago
You use a flat guide surface: either a set of rails, an aluminum ladder, or just a good straight piece of lumber (a 2x6, 2x8, or 2x10). I've gotten good results with a 2x6 and a 2x10. The guide surface gives you a flat surface on top of the log, and this flat surface becomes the guide surface for the next cut, and so on.

There are different methods for the first cut but the way I do it is by using 5" nails (40d bright common). I notch 4 nails and level two on each end of the log. Then pull a nylon string over all four nails making two parallel lines. Then stagger nails down the log the same height as the nail heads. After that, remove the string and place a flat board on the nails. be sure to adjust the thickness of the attachment to cut below the nails. Use the board as a guide for the milling attachment. This is a good method because it is inexpensive, you can mill a log of any length by sliding the board down the nails as you mill, it makes a flat level surface and if you turn the log 90 degrees and make the surface plumb by using a level then you repeat the process for the next cut and you will have a 90 degree edge.
For smooth cuts that do not stray you need to properly maintain your bar and chain. Make the cutters all the same length when you sharpen by using divider calipers and use a depth gauge tool to get the depth gauges all the same height.
Make sure your bar is straight and the grooves are square with the side of the bar. If they are not then use a square and flat file. If the bar groove is worn too wide causing slop in the chain then either use a bar groove tool to bring it back to the proper gauge or use a chain with the next size gauge (.050 to .058). Use a feeler gauge to make sure it is wide enough for the next size.

ProductExpert6· 11 years ago
You would start by placing a straight board mounted to the top of the log. Then make enough cuts until you get down to the width of the board you want to use. At that point you would be able to make straight cuts.

The metal rails do not come with the kit. You can order the from northern. They come in two length's and can be but together to make longer for milling longer logs.They come in two length's, 5ft and 9ft.

Type of chain
Does this unit require a special chain ? I have used my saw without your guide but it doesn't cut very fast or too well.

Tmac24· 10 years ago
Yes needs a ripping chain but I have used a full chisel and it works pretty good
Helpful?
-
BJ01· 11 years ago
Till now I have used my normal chain and have had no issues. The chain has to be sharp. Also this is a slow process and this kind of cut puts a lot of strain on the saws which are really great at cutting across the grain - not along it.
I can't see how you could have gotten very far freehand without the mill attachment.
Note that you can buy rip chains for this which have cutting edges that are a lot more aggressive than the normal chain.
Helpful?

ProductExpert43· 13 years ago
Your regular stock chain will work if sharpened correctly. All top angles must be the same uniform angle(25, 30, 35 degrees) and your depth gauges must be at the same height, no more than thirty five thousandths below the cutting edge of the tooth. For better ripping results, re-sharpen your stock chain to zero (0) degree top plate angle from the 25, 30 or 35 degree angle mentioned before. The zero degree top plate angle reduces the power needed to rip and produces smoother lumber than your regular stock chain.

Was wondering if you could use the model G777 on logs that were larger than 20in dia. Didn't know if you made your cut than came back the other way if
it would leave an offset line where the two cuts met?

NO! if you bury the bar tip into the log you can get really bad kickback!
Helpful?
-
BJ01· 11 years ago
I would not use this mill for logs that wide. This mill is designed for bars 20 " or less, implying that you can only cut a log with a diameter of about 17 " as you lose some length once it is set up.
What you don't want is the tip of the saw buried in the log - it must cut through and stick out the other end. This could be very dangerous if you bury the tip of the saw in this kind of cut.
Please get a bigger mill and a bigger chainsaw.

Yes it will work, but you will need to keep an eye on the engine; don't want to overheat it. I started out running a Stihl 011 (41cc) on my Small Log Mill & kept giving it breaks to cool off. Maybe I'm paranoid, but the engine really heats up. I eventually bought a used Stihl MS460 (76.5cc) that is designed to run hard all day. Now I go through logs faster & use less fuel. If you are thinking about buying a chainsaw mill I would strongly recommend a design that supports the entire bar or your boards will be thicker on the chainsaw bar tip side where there is no support on the Small Log Mill. Look at the Alaska Mill III or comparable from other vendors & buy the model that will handle the longest bar your saw can run; in anticipation of a future upgrade. Happy Milling. 1CRAZYLOGGER.
