Well, whatever you do with it you have created a nice looking machine.
Did I guess correctly about the number of teeth? If it is 52x16 with a TCW hub and 28" wheels, you will have gears of 68.5, 91 and 121.3 inches.
We have (in the south of England) an annual time trial competition (for 'The Tin Can Trophy') for hub geared machines. One of my clubmates has won this and he has a TT machine with an AW hub (same ratios as TCW). His sprockets are 60 x 18 which give very similar gearing. My friend says that for TT purposes this is virtually the same as having a single freewheel of 88", since the 68" bottom is only useful for warming up or riding out to the start, and the 120" top is too high to be of any use at all.
It just so happens that he's a strong enough rider not to need gears!
