SDP/SI does sell 23t 5mm HTD pulley stock, however.
Ah, I didn't think about the counterboring issue. That makes things more difficult. On 2791 we just used 1/8 washers between the bearing flange and the tube to get everything to fit. This is a bit more compact than going to 2" wide tubing but lets you use smaller pulleys.
