My Housing set broke at the front end where the pin goes.I thought I was going to have to buy a new saw. Instead a friend fixed it by bending a piece of stainless steel that fit the very end. Drilled holes for the pin and one to secure it to the housing. It is stronger than ever. Don't throw your Saw away. It's one of the best tools I have.
I can't remove the 3 3/8 circular saw bolt and have buggered it up- I will need a new bolt- is this a reverse thread ie clockwise to loosen or counter clockwise to loosen- used WD-40 and may need to slot the head to remove.
