Hi All
I am new so first of all hello. Not sure if this belongs in this category so if not please feel free to move it.
In general I am new to woodworking and have only recently bought a cheap and nasty band saw (300mm x 300mm x 80mm capacity 350w).
Now I know in theory kickback shouldn't be possible on a bandsaw but I was making a heart shape jewelry bandsaw box for my wife's birthday next month and had successfully cut the heart shape blank and cut both the lid and bottom of the box. Next I brought the solid heart shape back to the saw and started to cut out the inside of the box. I was making relief cuts and stopping the blade to remove the offcut every time I completed a relief cut and all was going very well until the last relief cut was just finished and suddenly there was a very loud bang and I got hit in the chest (table is roughly between my waist and chest height) with my work piece. What I assume was actually a bad kick down had occurred but oddly in the process the walls of my box had been thrown through the blade cutting through it and into my chest which was roughly 6 inches away. I can't really say it hurt but I did certainly feel the force behind it even for a under powered 350w hobby saw. Whatever happened also badly bent beyond repair my new blade which was a 4tpi skip tooth which before that was performing incredibly well for the curves of the heart as well as small resawing jobs.
I am not really sure what I have done wrong and somewhat reluctant to try another bandsaw box until I can figure out how I can avoid the same mistake.
I have Googled bandsaw kickback but there is only a few references to it on various forums and the usual replies are "it wasn't a kickback but a kickdown" but ultimately the work piece did travel with force from the saw into my chest… not really worried about minor blows to the chest but worried similar incidents could easily involve loss of a finger or two. I am happy to call it a kickdown I just want to know what I did wrong and how to avoid it?
The only thing I can think of is that the relief off cut which was contained within the walls of the heart shape has got caught at a funny / freak angle by the blade and that it's just a rare occurrence. I don't see any other way I could have removed the centre of the heart shape differently on the saw and was following the same procedure I have seen no end of other wood workers do.
Anyways sorry for the long post and any advice or insight would be greatly appreciated.
Many Thanks
