I made this chain tensioner awhile back. It worked great on smooth roads but not so hot on rough trails (maybe it needed a design tweak?) The reason I just didnt shorten the chain was I liked to switch cogs based on race terrain and conditions.
Took some flat aluminum, drilled some holes as shown below. Then stole a derailleurs wheel and screwed that onto the plate. The trick is to bend the plate the right amount.
