Outstanding Chainsaw Jig for Slabbing Logs
I purchased this to slab a maple tree using my Stihl Wood Boss chainsaw. The item arrived on time and as described. Assembly and attaching to the chainsaw are simple. You should have a small ratcheting torque wrench, as the bolts that clamp the saw bar and hold the depth platform in place call for specific torque settings. Using rails to get the first cut, slabbing a log is straightforward work, although it's a good workout. It also pays to build a saw buck to hold your logs about 2' off the ground -- your back will thank you (ya' I have a tractor and can cheat using it to lift large logs). I used both 10 degree ripping chains and 30 degree cross cut chains. Ripping chains give a smoother surface, but are a bit slower - just keep them good and sharp. I used this on Stihls with 18" and 36" bars, and it worked perfectly on both. I tried cutting a 30" slab with the 18" bar, cutting from both sides, and it doesn't work very well, so use a saw bar longer than the logs. I also bot the Granberg winch. It works great too, and if you have a lot of slabbing to do, is a sound investment.

Works great, but you will need some accesories
This is easy to assemble and fairly easy to use. It does require some practice to get the hang of it, but that really only affects how fast and easy your cuts are, not how they turn out. If you're using a guide for the first cut, you can't really screw it up unless you go out of your way trying to. Some tips: -Make or buy a guide rail system. This is a must for your first cut, no matter how small your log is, you have to make it straight or all other cuts after that will be off. I made rails using 2x4's and use lag bolts to secure it to the end. You can buy the rails from granberg, but they are expensive. -There are lots of videos on youtube of people using the system in different configurations. Take some time and watch a bunch of them, get to know some do's and do not's by watching other people. Lots of good ideas out there. -Use wedges, even for small logs. The clamping force of gravity slows you down and squeezes the blade and that's bad for lots of reasons. -Get a small torque wrench. You don't want to over torque the screws holding your saw bar in place, you could bend it. 10-12 lbs max according to the instructions, so you have to have a wrench that goes that light. -Debark your logs. Cleaner and easier on your chain. -MOST IMPORTANT: Get a ripping chain. I did my first two logs with a standard crosscut chain that came with my Stihl. It worked, but it was a long, slow and very tiring process. I got the ripping chain and it was slightly faster, but a hell of a lot easier (for me and my saw.) I ordered mine from Granberg's website. They give you step by step instructions for how to order it so you get it right. FYI for chainsaw beginners, these are rough cuts, if you want finished boards, you will need to run them through a planer a couple of times.

very easy assembly
How easy is it to put together? Well my 7yr old assembled it completely by herself in about 30 minutes with her 1/4" drive ratchet and 1/2" socket, mostly going off the illustrations since she couldn't comprehend some of the words within the instructions. To be fair to anyone who says it wasn't an easy to assemble unit, she does have much higher than average mechanical ability for her age and some significant experience with hand tools. Figure an adult who has equal mechanical ability plus the ability to actually read all the instructions should take 15 minutes maybe. Quality of the parts I would rate as very high as to be expected on a premium brand product, which is why I chose the Granberg Alaskan G777 over one of the less expensive ones. The supplied hardware all appears and feels to be good quality. The set bolts to hold it to the bar are significant as are the plate they thread into, which is only welded on the ends which would make it not as bad to cut off and replace if ever needed and seems to have been done on purpose. The welds are clean and all other welds look very solid and run full perimeter of other joints Looks like it can take some heavy use with little to no wear and any wear parts would be easily replaceable.

Good quality, assembly required
Works well; cool way to use random logs you may have lying around. A bit fiddly to put on. Make sure you hold up the chainsaw end adequately (push down into the log from the bar nose end), otherwise your items will be a bit wedge-shaped. Mine did have clear plastic included. Be prepared for some assembly. I think it could have been a bit more assembled for ease of intial use. Overall quality seems good.

Am enjoying cutting slables and boards
Have only cut up a few 10 food, 25 inch pine logs thus far. Had to call it a season at camp before doing more. However that was great fun, and the wood is snickered for a project this summer. I have many more downed trees that will be getting cut up this summer. Easy assembly, good directions. Plenty of YouTube videos on the use of these units. I found this one to have a good price, was very stable and consistent in the cutting guide. Used an aluminum ladder for the initial cut with a guide block at each end - worked great, after that you guide off the log your cutting. Even my first few cut came out great, and after a few logs it just becomes a matter of being patient.

Premièrement, c'est très bien fait, les instruction d'assemblage sont très simples et facile. L'appareil est solide et fait aux états-unis. Avant de vous lancer dans le découpage, il est recommandé d'équiper sa scie d'une chaine à fendre verticalement (ripping chain).. La différence est dans le nombre de lame. Il y en a moins donc ça coupe plus franchement le bois. En contre-partie, votre moteur doit être assez puissant. Ceci dit, j'ai une Echo 490, 18", .50gauge, .325"pitch. Le travail était laborieux au début car je voyais que le moteur forçait puis, j'ai trouvé ma vitesse de croisière pour fendre mon bois. Les coupes sont bien droites et je suis très satisfait du travail. Il ne me reste qu'à planner mes planches. Je recommande ce produit sans hésitation.

Very nice product. I used it with my rancher 455, worked great for relatively small projects. Well worth the cost. Good setup that it holds the bar securely. I used it with a 20 inch bar, and just regular chain. Plexiglass is a nice bonus to avoid more sawdust.

used this product to make slabs for outdoor projects and worked very well. Still using it recommend it to any one.

I've only used this a couple of times but it worked very well. There was a little bit of assembly but instructions were clear so it went pretty quick. It works as advertised and was easy to move along the log. Very good unit.
