I am new to using a spray gun myself, I have sprayed 6 sets of limbs and 2 one piece recurves..still learning the process. what finish are you going to use? From my research I was told the finish I use (Krystal) works best with a 1.4mm tip. I believe you can spray T-Bird with a smaller tip. I bought the $47 HF 2 gun set with a mini HVLP, it has a 4oz cup..I modified the 1.0mm tip and make it 1.4mm. I just sprayed a set of limbs, I mixed 3oz of spray, I had 1 oz left in gun when I was done. I had a HF $13 mini gun but returned it when I found out it had a 0.8mm tip..it should work for T-Bird or Buffalo Hide
