Homemade Tabe Saw - Part 1 - Motor Mount & Adjustable Bed




So I had a table saw motor from what was a cheap machine, that contained the start and stop button, drive motor, mounting holes and blade in one unit.  I got my hands on this probably 8 years ago, and it was part of a functioning table saw, which I think is still quite easy to find.  It was limited in what it could do, because the blade remained in one position and angle cuts were achieved by tiling the bed, which made cutting feel quite dangerous. 

I bought mine as an ex demonstration model for about £40 but you can find them second hand at the usual outlets.  The bed also didn't have any parallel groves for a sled or mitre fence.   So eventually I got rid of the machine but kept the motor, with the intention of building my own table saw one day.

The reason I wanted to make one, was so I could use it to do quick kerfing or coffin cuts on pieces of timber, and after making a sled, I could also make finger and bridle joints.

I had some nice ply left over which had got a bit damp.  I began by squaring a piece of 18mm and then cutting a rectangle out so I could later mount the motor as high as I could, to get the most blade showing.  I then cut a groove to hold the piece of ply which would hold the motor, followed by cutting two side pieces from 24mm and another from 18mm.  The 18mm piece was cut to fit in the groove with a protruding section which fitted between the shorter lengths of the rectangle opening of the first piece of ply.  This was a bit of simple joinery to stop the piece sliding around.  I cut an identically sided based which I screwed at the bottom and used insert nuts and machine screws at the top.  The idea was to open the machine up from the top when and if I needed to change the blade.  In retrospect I could have cut an angled channel near the blade opening which would have let me do this.  I later cut groves on the side and mounted inserts nuts which would allow me to raise a second skin or bed and change the depth of the blade. 

In the next video I will make parallel groves, a sled, a guide rail and extraction system.

    I have watched most of your videos and found them to be excellent. They are informative, well edited and were much the better for not being narrated, which can be so annoying. They have reinforced and demonstrated the need for accurate measurment and the simple tools that make that happen. Thank you.

    Beautifully made, craftsmanship is superb, video editing is highly impressive as well. Well done indeed.

    Nice job. Obviously, you have done many projects. The part at the end, where you put the sled on the running blade scared me abit and made me laugh. I guess ee have all crazy stuff like that.

    Yep I put on some goggles at that point, but it was quite safe as the guide rails on the bed also kept the piece in place and the new blade made cutting a lot easier. I also made sure the guys where around in case something went wrong! The only thing which didn't come across in the video which I am concerned about is the time it takes to stop blade from spinning, which is quite a while. I need to figure out a DIY magnetic braking system next to the blade?

    that is incredible work and brilliant documentation, just mesmerizing to watch

    wish i had any tools here at uni, i didn't even have a spanner to take the battery out of my girlfriends car when it needed charging.

    can't wait for the second part


    have drybag will travel

    Nice job dude, Home made tools are the best. That track saw is also the best, I'll have to invest :)
