Question: Will this work with longer than a 20 inch bar?  I have a stihl 046 with a 24 inch bar I would like to use.  Thank you
Document: Works as specified. Gives you the ability to make lumber from trees with some hard work. I used it with a Stihl MS290 with a 20" bar to cut live oak about 12" in diameter. Anything harder or thicker would require a bigger saw.The product is well made. I gave it 4 stars because it really needs the braces on either side of the bar for a more consistent cut like the higher priced model.
I used a Stihl MS 361 saw with a 20" bar, which might be a bit overkill. By using gentle pressure, I was able to get some smooth finishes on the boards, although running through a planer will probably be necessary for most projects. The Granberg slabbing rails are next on my "to get" list. I made a temporary set out of some scrap lumber, but it did not work all that well. I would not recommend using this without also getting the ripping chain.
I have never ripped any lumber but I had a few cherry trees cut down in my yard and it seemed a waste to let lumber go. So, I bought this for use with my 18" Husquevarna and it worked well. Not fun work but this kept the chain saw lined up relatively well, I'd guess within 1/4 inch from one side to the other on a 14" wide piece. Now if I could only find a chain that would stay sharp.
I purchased the Granberg small log mill G777 because I have a smaller saw and I will probably not be cutting logs greater than a 20" total diameter. The mill came unassembled which should hav been a problem, but the instructions seem to be for an earlier model of this saw. Some logic and guess work is involved. Once the mill is together it is quite easy to attach to the saw bar, but a wider bar would make it easier as getting too close to the chain channel will bind the chain.
Simple enough to use and makes decent boards. Get ready to put in some hours and buy a bigger saw. I'm using a 40cc husquarna and it takes about a minute per board foot on a 12 to 14 inch wide  pine tree, but I'm willing to put in the work. Definitely worth the money.
I bought this mill and have enjoyed using it. Works as expected and does a good job of keeping your lumber in tolerance, usually within 1/16th of an inch overall. I would recommend this item to anyone wanting to mill lumber without the investment of a large mill. I would add that the mill is most effective if you have a chainsaw that can handle the work. I would definitely stick with a 55cc or larger saw for this mill. You really need the power in your saw.
3) You must be patient and let the saw do the work. Don't expect that your chain saw will be as fast as a professional milling machine. 4)Using some type of guide rail system for your top cut is a must but you can use a simple jig using 2x4's and some angle iron brackets. My first few boards were terrible but that was my fault and once I got the hang of it, I was milling 2" thick Ash boards.
I purchased this product to mill a pecan tree that a friend was having cut down. The mill went together easily and mounted to the chainsaw firmly. I watched a short video on their website to get a feel for the procedure. The section of log I had was about 12" to 18" in diameter and about 9 feet long. I used a husqvarna rancher 20" chainsaw with a standard crosscut blade. Each pass I made took 10 minutes + to complete and it was some work.
This is what makes/brakes a company in my opinion. I called the Granberg office and they rushed me a new part. I was back in business in no time and I could tell that the new part had been redesigned with larger weld areas. Good work guys. I'm still giving 4 stars since it did break, but I'd put 5 stars for the customer service.The next project went much smoother, cutting 20" diameter sycamore logs. The ripping blade is the way to go.
This does make a nice flat cut but it is a clumsy device especially when attaching the saw. I ruined one bar when mounting the saw, it slipped slightly and the screw crushed the track.
Answer: yes
