I’ll never be a master with the blade as James is but I do love sawing/piercing.
Best pieces of helpful advice I had early on:
The standard “keep your blade tight “
Use a light grip and keep the blade vertical to the surface (usually).
Don’t watch your blade; focus on where it’s going.
After you have put in 40 hours sawing and piercing you’ll be able to really enjoy this. (this period to be followed by on-going practice, practice, practice)
Maximizing the ergonomics - bench pin and chair height to minimize negative body effects of bending, twisting and straining muscles.
I still have my old German style saw frame but got my KC frame soon after they were introduced and I do prefer it.
