A Poor Mans Table saw

My improvised table saw set up.
Using a portable circular saw screwed under a sheet of MDF.
It bolts back to a "Workmate" bench for stability and has a set of clamp on fences as guides.
Only intended for a specific ripping project but so far ... works well.

Just hope I dont loose any fingers in the process.
Will be carefull !!
If it works well, I may expand the idea and build a better set up.
(Will see.) perhaps safer to buy one ready made ?
