?Well yesterday I worked on the mantle I mentioned earlier seeking hanging advice. It took some time because my neighbor had miss calculated and the log was not long enough for main section and a return on each side. He had to go back and cut more off the same tree to have extra for the 2nd return.

Anyhow, it was more challenging than I thought on one account, more on this later. Log was 11” wide, 7” thick and 8.5ft long with live edge front. It weighed plenty, I guess around 150#.



It was not an issue to plane the bottom on jointer. I was not sure if the planer will self feed this behemoth but it did with aplomb. I did not attempt to joint the rough sawn back 90 deg to the top or bottom because I just did not think the tradition way would work even with a PF. Should I have tried holding this log face against the Dual51 fence?

The largest blade (350mm) that fits my K975 would not cut anywhere near 7” so all cuts required 2 passes. With only 1 (somewhat) flat side to put against the xcut fence each 45 deg cut required one pass in the conventional way with the xcut fence set to 45 deg. The 2nd pass had to be done with the xcut fence installed on the opposite side of the outrigger and set to opposing 45 deg. However the material had to be placed against the opposite side of the xcut fence than conventional use. This is where I was surprised. I missed the fact that there is not enough room (between fence and blade) to fit 11” wide material. This would be okay with a normal blade but 350mm blade does not go below the table. So change blade and bring it up into the material. So every 45 required one cut with 300mm & the 2nd with 350mm.

With not having a flat back it was very hard to get both cuts to line up. So shim here or there to get as close as possible. It turned out fine.

I would love to hear if there is a way to joint such big material and any other technique I could have used.
