Is this a straight enough beam element? Or should I use hose clamps. Thinking about turning it in my lathe to remove the pipe stop ridges inside to create a clear path. | Is this a straight enough beam element? Or should I use hose clamps.

I used a short length of pipe to secure the tape in the T. Beveled the edges a bit to make it easier to start.
