Canada Tire (3079 Boulevard des Sources, Dollard-des-Ormeaux, QC H9B 1Z6) had a sale on cordless saws. A regular priced saw is more than $100.00. This saw was about $20.00.
There were about five of them in opened boxes in the store.
I think they want to get rid of them.
The saw came without a power-pack.
I did not want to buy their power pack for two reasons.
1) The cost
2) The weight on the saw
I decided to mod/hack the saw to run on twelve volts, or a car battery with a short wire/line.
I needed a tool that could turn the screws holding the saw together. A "T-15" bit is required, so had to buy a tool.
Buy Wire, three meters of two stranded wire
Two alligator type clips for the end of the wire.
A 12 volt battery with high current output.
Step 1: Step 1
Open the saw with the T-15 tool.
The inside of the saw.
First thing to go was the safety lock on the trigger. It falls right off.
Step 2: Step 2
Cut off the speed control. I don't want to waste any power. I am going with the full 12 volts .
Cut as close to the ends as possible. There is not a lot of wire to spare.
Step 3: Step 3
Confirm the motor works on 12 volts with some wire and a 12 volt battery.
Step 4: Step 4
Solder the motor wires to the high power switch.
I found the heat required to solder was tremendous and I was using a 150 watt iron.
This is the reason I left the two lower wires on the switch attached, they would not easily come off.
My red and black on the top of the switch are vice-verso because the red wire going to the motor was a bit too short.
When attaching the power cord I connected black to red.
Step 5: Step 5
Attach the three meter length wire/cord to the bottom of the power switch. I soldered to the two existing wires and then capped the joint with marettes.
Step 6: Step 6
Close up the case. Tighten the screws
Closing this is up was somewhat difficult due to this saw model being able to twist.
Step 7: Step 7
Attach alligator type clips to the end of the wire.
