    ok slab cracking quetion time???

    I've only experienced what you described when milling a tree that was leaning or previously growing on a hill. Either way, it is likely bound stress in the log being released as you separate the piece from the rest of the log. I assume this only happens on the cut releasing the pith? Sent from...

    Walnut stump

    If you absolutely must freehand it, use a chalk line and a level to mark where you want to cut both in the side (vertical wall of the log) and top (recut to give yourself something you can mark up); make sure your lines on the vertical wall are plumb. Then just attach a spirit live to the top...

    Moisture meters

    Unfortunately, there is no magic number. It depends on where you live and what the weather is doing that week. It's all about being at equilibrium for your area. For me, on most species it's 11-13%. It can go lower if it's been really dry for a while. I like to watch it like I described above...

    Moisture meters

    I use a pinned lignomat meter. I check everything about once a quarter on the wane edge. I have found that edge without bark is within one percent of anywhere else on the board once below about 16% while drying. I really don't care about the number, I just look for it to come to equilibrium...

    Granberg vs. Holzforma 36" Alaskan Mill (A Comparison)

    I have found them on eBay in 24" and 36" lengths, nothing larger than that. In the end if you can find the longer rails reasonably priced, you can just take all the parts off a 24" mill and have a larger mill. Sent from my iPhone using Tapatalk

    Granberg vs. Holzforma 36" Alaskan Mill (A Comparison)

    I have milled a few logs with this mill frame since I did my initial comparison. Also, I assembled the mill and made all adjustments to it with the tools included, just to see if it came with everything needed. Overall, for 137USD, this mill isn’t bad. Some stuff that I ran into is the handle...

    Granberg vs. Holzforma 36" Alaskan Mill (A Comparison)

    Next is the rails, both the square tube and the round rail that feeds through the bracket. The square rails have identical dimensions. G weight is 586g, H 610g. I believe the difference in weight can be attributed to the paint used on the Holz parts. Granberg round rail: 692g 0.876” OD Holz...

    Granberg vs. Holzforma 36" Alaskan Mill (A Comparison)

    Alright, so I went through with it and bought the Holzforma mill from China, via Ebay. Total cost was 137USD shipped. I took some measurements to help with the comparison and will provide you with my general impression of each of the pieces. Warning! I had to go back and directly attach the...
