One of the most important tools in any workshop, or DIY amateur, is a table saw. Since I don’t have a workshop and I am not used to make big things, my perfect tool would be this saw, but very small.
If we look for a small saw we’ll see that there are only two or three options in the shops, and are quite expensive. So, I opened the Solidworks in one hand and Google in the other y started to think what could I do with my limited tools.
I bought the most of the parts in ebay and this is the list of materials:
- MDF Wood (if was cut and sent) – 12 €
- Aluminium sheet de 300 x 200 x 4 mm – 7 €
- Sew motor with pedal – 27,5 €
- Motor Flexible Coupling Coupler – 5,2 €
- HDPE sheet 10mm – 3.3 €
- Screws, nuts and washes – 7 €
- Aluminium sheet 100 x 100 x 3 to hold the motor – 2,3 €
- Bearing – 2,28 €
- Arbour – 13,9 €
- Circular saw 4″ – 7,29 €
SUM: 88 €
Also, It’s can mount different types of saw (shaft diameter) and this it’s not usual. It has a cut of 20mm and this is a lot for this type of saws. In fact, I could increase the cut with a bigger disc.
And here are the pictures…
Here is the video of the first tests. In the video I’m cutting HDPE (10mm) and MDF (18mm). The wood is cut worst but it’s because the saw has the teeth too small. Any way, the result is great.
I’m really happy with the result. If I would have had better tools I had made the bearing holder in aluminium, but…
* Update with a protector
After a bit more of Solidworks, a bit of plexiglax of 4mm and a couple of hours I have a protector.
* Second update
After some of work with the saw, I found out that the sew motor has not enought torque. Finally, Finally after forcing it burned. The solution has been to replace it with a 12V motor with gearbob. In particular this that operates at 12V and 1200 RPM. The result has been great, works much better, and cheaper. But you need a regulator or an adjustable power supply, to be able to regulate the speed of the motor.
