Hello,

I am new to the web site and leather sewing. I purchased a Tippman Aerostitch machine and need some information on needles please. 

1.) Where I can find needles for this machine, I tried contacting the company by email and phone with no reply?  The auto reply says they will reopen on Jan. 3rd!  well that didn't

      work very well!  

2.). Does the smaller number designate a smaller needle?  I have some large needles that came with the machine, but the projects I have need smaller ones.

3.) Does anyone know where I can go to find answers to tension issues I'm having?  At one time I had the tension set properly, then I had to change bobbin thread after that, poof!

      I've tried using the adjustments in the manual and even changing bobbins to no avail. 

     Any assistance anyone can provide will be greatly appreciated.

Thank You,
