BT30 Spindle

This is a model of the BT30 spindle that is readily available off eBay from China. It is supposedly rated for 2hp and there are options for 3000rpm and 6000rpm. This design was made using the dimensions provide on the eBay item listing and also from other Google image searches, so it's pretty close in terms of the detail, but the overall dimensions are exactly what was shown in the drawings.
