Freewheel disk brake adapter?

[thxcuz]

Has anyone ever used one of these https://www.bicycledesigner.com/bik...sc-brake-adapter---free-or-flip-flip-hub.html

I have a spare freewheel hub and I was thinking of putting it in front with a disk brake. eBay has the adapters for less than 10 bucks.

Just wondering

Thanks
