Combustion guns are considered firearms in the state of Texas. You would have to follow any laws that would apply to a firearm during building or discharging.

Sec. 46.01. DEFINITIONS. In this chapter:
......
(3) "Firearm" means any device designed, made, or adapted to expel a projectile through a barrel by using the energy generated by an explosion or burning substance or any device readily convertible to that use. Firearm does not include a firearm that may have, as an integral part, a folding knife blade or other characteristics of weapons made illegal by this chapter and that is:
(A) an antique or curio firearm manufactured before 1899; or
(B) a replica of an antique or curio firearm manufactured before 1899, but only if the replica does not use rim fire or center fire ammunition.

Brings to mind the day when one of the guys at the telephone garage brought in his tennis ball cannon, made out of juice cans soldered together, to demonstrate in the parking lot.

He fired one, and we all "oooohed" and "aaaahed" as the tennis ball rocketed almost to the limit of vision and then came down to dent the roof of one of the phone trucks, and then another went way up and came down on the pavement and bounced and bounced.

And then he fired it and it made a really funny noise, and he said something on the order of "Ow, that doesn't feel good!" and it didn't look good either, what was left of his little finger hanging by a thread of tendon from his right hand.

One of seams/joints of the cans gave way and most of the pressure had vented out right where he was holding it.

The company charged him with an absence for going to the hospital.
