Help with 21" rear wheel build

[Rakkassan34]

I'm wanting to build a 21" rear wheel for my B&S V-twin board tracker project. I've never build a wheel before but determined to do it myself so bear with me. I purchased a moped rear hub, 36 spoke drum brake, and a 21" motorcycle rim. I'm planning on using 10ga spokes which I think is the norm for these not sure. I'm in a hurry to get to work but will post pics and measurements this evening. If anyone here has built one of these before any build tips and finding the right spokes info would be greatly appreciated. I'm on a deadline with this build as I'm planning on putting it in this years Beatersville car show in Louisville Ky this March.

Ive got a pretty good wheel building book on PDF. if you pm me your email address I will forward it to you. As for spokes I like holmes hobbies but they carry a limited selection in the 10 ga size.

Took me a couple of days but I finally got the pics of the hub and rim. Thanks to Chainmaker I might get this figured out but if anyone else has any tips they'd be greatly appreciated.
