Where is the blade/spindle lock on an old Skilsaw 5250 7 1/4" circular saw?

It likely does not have a spindle lock. I have a similar saw and there isn't one. I use a heavy rag or glove to block the blade while adjusting the bolt.

Where is the blade/spindle lock on an old Skilsaw 5250 7 1/4" circular saw?

I just use a vise-clamp to grab the blade and rotate till it is block by the saw plate. This is always secure and never slips.

Three things can cause wandering (or what seems like wandering). The first is a misaligned table and/or fence. The cut isn't actually wandering, but it seems like it is visually because of how the ...

Based on the project (chicken coup) and the very coarse drawing I think a reciprocating saw would be more appropriate and safer if you really need to cut it in place after installation. (But why?) In ...
