[TheThinkTank] Learning Spanish in the shop

Does anyone have any good resources for learning Spanish? Specifically ones that might be good for learning mechanical terms and language, for use in our shop?

I'm ashamed to admit I've made it this far with barely passing abilities in Spanish speaking. I'd personally love to make my interactions in the shop more open and welcoming to folks who aren't as proficient in English, and we're working as a shop to move in that direction.

Do any of you know of any good bike mechanic books written in Spanish? I'm thinking that may help as well.

Any resources or things you've found helpful in teaching the staff bikespeak in another language?

Thanks!
