For drawbar removal, put the drive in the lowest speed, loosen from the back end with spanner or wrench as necessary & when it is clear of it's seat about a 1/4" use a deadblow hammer to drive it loose.
As for 3 phase converter, Rucker has 10% discount you can use at AmericanRotary.com. If in the USA setting up a home shop & insist on using 480V 3 phase be aware that simply opting to get the phase converter upgraded to 480V will not do. It's in fine print output V = input V. Now I wait for a transformer that costs more than what all I ordered from them to start with. I simply did not call before ordering. Ideally, you would get a 240V phase converter & add a 3 phase transformer to the output to run a 480V machine. Single phase 15KV 240/480V transformers are much more expensive. They are great to talk to - just wish I began with the phonecall.
Looking forward to your updates!
