I have a 1 ton press from harbor freight to push the broach through. It can apply enough force to cut a keyway in steel, but it doesn't open quite far enough for the broaches I have used. Makes it difficult to get things started. How will you press the broach?

I have a 4? ton arbor press upto ? broaching.?
