In this instructable I am going to make a mini powerful table saw out of a bunch of MDF sheets,a 12v DC motor from an old viper mechanism of a car and some UPVC pipes.
This mini table saw is very small but still it has bunch of power to make a good amount of cut through relatively thick wood.

Lets get building.....
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Parts
To start with we have cut down the required size parts from a 8 mm thick MDF sheet. The top measures 12 inch in square while the motor mount is made up of 3 pieces of MDF sheet.
Step 2: Motor and Motor Mounting
The motor that is used in this project is a 12v DC motor from the viper mechanism of old cars. This motor is easily available cheaply from any auto parts shop and has alot of power for the subjected task.
The motor mount is made out of MDF sheet and the motor is mounted to it using four nuts and bolts.
Step 3: Motor and Motor Mount
I have used a custom made motor adapter to mount the cutting blade on the motor. This adapter is specifically made to fit the 6m motor shaft and have the same coupling as of a small size angle grinder so that we may use the same cutting blade as available for an angle grinder.
Step 4: Blade Cavity
The cutting blade cavity is made by frist drilling a bunch of 2mm holes in the top and then making a straight cut using a jig saw. The motor along with the blade is inserted to check the clearance.
Step 5: Mounting the Motor
The motor is now glued to the bottom of the top plate using super glue.Two side supports are used to ensure that everything is firmly held in its place.
Step 6: Making the Base
The base of the table saw is made out a four 1/2 diameter UPVC pipes and a 8 inch square piece of MDF sheet. First four pieces of pipes are cut down using a hand saw having a length of 4.5 inches and then glued to the base plate.
Now this part is glued to the bottom side of the top plate ensuring that symmetry on each side is maintained.
Step 7: The Side Support/cutting Support
The side support is made out of MDF sheet such that it slides over the top of the table saw and can be fixed at any point by tightening two side screws.
Since MDF IS soft material so I have applied super glue to the sides of the top plate so that whenever i tight the screws that didn't damage the side of the top plate.
Step 8: Measuring Scale
The measuring scale is made by sticking some 1 inch wide white stickers along the two sides of the table top and then both the sides are marked using a measuring scale.
This measuring scale helps us to make precise cuts without using a measuring tape each time before making a cut.
Step 9: Wiring Everything
Since the table saw is powered by a 12v DC adapter so the wiring procedure is quiet simple.The power coming form the input jack goes through a switch to the motor.
Step 10: End Results
The end results are pretty good.The finished table saw is small enough to easily fit on a desktop table and its really light weight. Regardless of all that this mini table saw has got enough power to make cut in the wood upto the cutting height of the blade easily.
