This morning, we finished off the last two rafters hanging over from yesterdays work. Then we adjusted our Bevel Slicing Machine to the new angle of 57 degrees which is by far the biggest depth of cut we have to do. The final cut surface spans across 115mm with a large cut-off pieces.
These-bevels-are-very-wide
It is very slow work and very hard work for the electric motor to cut the wood, the teeth on the saw blade only just comes through the cut which means the blade is actually cutting through about 250mm of material and that is enormous amount of work!!
We did a small rafter J9, to test that it did the job and we took that one outside to fit it into place. It was ok so we glued and screwed that one! Then, we tackled the longest one, J6 which has a funny “half” bevel end on it because it fits into a metal bracket. This one also went outside and got installed into place too.
but by this time, it was getting dark so we just carried on slicing the bevel ends on the remaining rafters in the workshop, as mentioned above, doing it slowly and carefully without over straining the engine and equipment.
So tomorrow, in the predicted strong winds, we will take the six rafters outside and install them all up into the roof and then finally measure the remaining rafters we were going to do today!
