Many jobs in my workshop involves long, straight cuts. Having build gantry type Maslow, a natural extension of functionality is circular saw adapter. Here is my proof of concept prototype.
I found hand saw made by Kawasaki, type K-TRS 1200-56 suited very well to my purpose. It is spring loaded so motor and blade pops up, have 45deg mitra and weights around 8kg. In Fusion 360 I design sled and cut it on my Maslow: three operation - pocketing, slot and contour cutting (circle in the center is left over from my first Maslow sled).
I design and printed modified rollers used for Mark II with additional ball bearings and latch. I mounted furniture magnetic catch on four latches.
This way I can fix position of my saw blade horizontally (for ripping)
or vertically (for cutting)
Another set of magnets is used to lock gantry in position. I used a pair for every corner of gantry - if polarity is correct (NSNS) holding force is stronger
Maslow sled is is removed and chains secured - I do not want to loose calibration;
Now I can insert to gantry the table saw assembly in place of router sled;
Operation is simple: material is placed on the table; saw is moved to the ripping position and latches locks saw in place.
Depth of cutting is set and gantry is moved by hand, (picture after ripping)
For cutting, sled is flipped 90deg, gantry moved to desired position;
and locked by magnets;
Here is short video of cutting
This is my first build and I see a lot of challenges ahead: material handling must be improved - how to hold it and move around, how to precisely measure cut distances, are magnetic latches good enough, is whole assembly robust for quick set up and going from Maslow operation to table saw operation and back, etc. etc. - only practice will show - here is overview of sled assembly.
Modified rollers are already in Garden. Latches can be cut from plywood on Maslow. Support plate depend on the saw model.
I will let you know how whole assembly performs after couple of projects. Spring is in full swing, garden require attention and my daughter waits for her SUP… “I need a vacation”

, but why is there a center hole in your circular saw? is t for better aligning? or was it an old maslow sled?
, I feel the same … He hasn’t been back to answer you
