Understand where you're coming from Pierre but I am still a make do and mend merchant, adapt, adopt, convert, pervert whatever.
Somebody sent me a set of their old blade guides and I have since gotten rid of that saw so they are begging if you want them, I'll see if I can find them tomorrow and post a pic.
Assuming I can get to my shed without being assaulted by our rubbish bins or a loony tart.
You may be able to adapt them with the aid of a bit of square tube or some such gizmo init?
I now have 3 old Emco Star mosheens and am over the moon with the construct quality of them infinity pervertable with a bastard and spanner.
