Interesting! I’ve never owned or used a worm drive…Thanks for the tutorial 👍😎👍

[@mr.kongable]

Sure thing! They are quite a bit heavier with the gearing inside, but they really produce the torque when ripping framing lumber . Thanks so much for the view and comment.

@@mr.kongable being left handed … I think I always use the circular saw backwards anyway! But I adapted 😝👍

good demonstrate video! How should I make sure that the saw blade I bought online can be adapted to my saw? Will the size of the middle hole be different between 7-inch and 8-inch?

[@mr.kongable]

You will need to look at the middle hole size or the arbor size , I would think the holes would be the same but I also don’t have an 8- inch saw and I can’t say for certain
