I a new to the building scene and I was looking for a reliable and reasonably priced source for the Aluminum tubing needed for the Hilt/Blade Holder Emitter sections. I made a rough mock up of what I want from PVC found at the Home Depot, but now I want to move on to the "Real Thing". I am looking for either 1 3/8 OD 1 1/4 ID or 1 1/2 OD 1 1/4 ID for the Hilt and 1 1/4 OD 1 ID for the Blade holder. I prefer the 1 3/8 OD. Anyone have a good online source? Unless of course you are in the Allentown, PA area then local would be OK.
