I've been asked about what I use to do particular things for kite making. Thought it'd be a good opportunity to share a quick overview of pretty much everything I use. Some are more obvious than others.
My kite making tools..
I use a sewing machine (obviously)
2 - 6' Long Metal rulers
2 - 3' Long Metal Rulers
1 - 18" Ruler (metal)
1 - 12" Ruler (metal)
A Fiskars Rotary cutter.
A Paper Cutter (Office Style)
The normal assortment of Scissors (Including a heavy duty pair for cutting plastic) Masking Tape, Double-Sided Tape, A Dremel tool for cutting spars and these two pieces of Lumber.
One is also my updated Bridle Board. The other board is my full template for LE's (including Fold protection and wear strips. I have another marked out 72" LEs and another for 96" LEs. I also have an industrial style metal hole punch I use to punch the holes for the bungees.
These tools are pretty much the entirety of what I use to make a kite.
