Today, while it was snowing outside, we got down to repairing our Bevel Slicing Machine which suffered from a burnt out electric motor. We had ordered another handheld circular saw off the web and it arrived yesterday. but upon inspection, we decided that it wasn’t ideally suited for the job, the construction of the metal guard plate wasn’t flat enough to be bolted onto the plywood surface.
So we looked at two other circular saws we had and one proved to be much better and easier to adapt to the requirements. After discussing the pros and cons, we sacrificed this unit and converted it into our Bevel Slicing machine.

One of the positives was the ability to change the speed of the motor and we felt that this was a big advantage, especially we felt that the previous version was operating too fast for the size of the 300mm saw blade we needed and causing the wood and the glue or the pine resin to burn.
In conclusion, after slicing the final two rafters, it does seems to be the case that slowing down the blade does reduce the burning side-effects.
