The saddle thing it was a cheepo saddle and if I adjusted the stirrups longer the Blevins Buckles would cut the leather strap attaching to the girth and I honestly did not want to do poles girth-less
Hmm, I guess I don't understand how that would happen? Can you show a picture from underneath your stirrup leathers and fenders of where it rubs and how on earth it cuts? THROW THIS BIT AWAY.
It is one of the worst bits you can put in your horse's mouth. (Plus you've slapped a tie down on the poor fellow.)
That is NOT a snaffle, and that's why I asked you to post a picture because I knew you were confused as to what a snaffle is. Just because the mouthpiece is broken, does not make it a snaffle.
The bit you are using is a Tom Thumb. It has a horrible design, poorly balanced, a nutcracker effect in the mouth, and straight shanks that offer zero mouth relief. No wonder your horse is throwing his head. I would too, with that
in my mouth.
Do not use that Martha Josey Million Dollar bit either. That's going to be too much for him.
This is a snaffle bit
A snaffle bit means that there is no leverage and there are no shanks. (It really has nothing to do with the mouthpiece.) A snaffle bit is the type of bit you should be using on your horse
for the time being, until you can fix his head throwing from the use of the Tom Thumb.
This is a curb bit
It is a curb bit because it has shanks and it has leverage. This particular one has a solid mouthpiece.
This is also a curb bit, but it has a broken mouthpiece (what's called a dogbone). This particular bit is a Jr. Cowhorse bit and it one of my favorites.
This Jr. Cowhorse bit is still a curb bit (because it has shanks). A Jr. Cowhorse also is a mild gag bit, because the mouthpiece can slide around a little bit (on the reins on the side), unlike the curb bit above that has no sliding action because the mouthpiece is solid on the cheek.
However, if you attached your reins to the same rings the mouthpiece is attached to (rather than the bottom of the shanks) you can create a snaffle bit (because you are not using the leverage shanks).
For another example, this is a snaffle bit with a mullen mouthpiece. It is still a snaffle, even though the mouthpiece is solid, because there are no shanks and no leverage:
