Yes i used a tiny bit of water to keep the dust down.
The saw always sparked a bit but while cutting the concrete it looks like a bunch of wires to the commutator fell off, could see them twirling in there making sparks. Ive done a lot of long deep cuts with that saw and never had trouble before.i only cut for 30 seconds at a time, saw was cutting easily and didnt get hot. Could just be the water, the dust, or it was just time.
Brushes look great, i would need to reattach those wires to commutator but kind of means reengineering the connection.
Used to be a new armature was $50 but theyre really nla.
I was hoping this sort of fix was a normal thing but i guess not. Nice tool it seems wasteful.
Ok, new spt77 is $150 and hopefully fits the same case.
Wrt battery: sure theyre better and everyone loves them but ii still sting from the crap battery tools i bought in the 90s. Im fine managing cords and my grandchildren can inherit the tools. Wifes dewalt battery chainsaw is a frustrating joke, good for about 30 minutes of actual cutting. Nope im not going to get a battery skilsaw or concrete saw - they must think im stupid. Little drill sure, concrete drill no.
