HD15-f to DB13w3-m Adaptor

I need to use a normal monitor with hd15 connector in an Ultra1 workstation which have DB13w3 connector. I could find this cable adaptor, can I creat one. If yes what is the pin layout of both connectors femal and male

Is there any risk if I try to make an adaptor by my self
can some one give detailed pin out
