Question: My bar has no holes to bolt the mill on maybe I got the wrong bar ?
Document: 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.
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.
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.
I recently bought this device because I got tired of cutting fire wood that I would never end up using. I just got done milling a couple of ash logs and I learned a ton. This device does exactly as advertised. Couple of things that need to be clear:  1)Don't skimp on the safety gear. A high powered chain saw is just a few inches from your legs so spend the $75 and buy a pair of kevlar chaps.
I used this on a 48&#34; diam maple trunk with a 32&#34; bar, I cut end slabs 3 1/2&#34; thick in under 10min, I am very happy with this product.
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.
This chainsaw mill works exactly as they said it would. I have made dozens and dozens of boards from it already. It's a great product, easy to assemble and I will buy the next step up when I get a bigger saw. Shipped fast, too.
The performance of the mill depends to a large extent on the quality of your saw and a well sharpened chain. I thought that I had a sharp chain, but after struggling with the first two cuts I purchased another chain and discovered just how dull that first chain was. With a sharp chain the cuts are not too physically demanding.
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.
