You can make a captured draw bar but I have never had any issues with a stuck taper. I release my tapers with a hand held 1.25" diameter x 2" long piece of brass - I'm not hitting hard. You don't need a lot of torque on the drawbar.
One trick - are you locking the quill? if you don't the quill will just bounce and you have to beat the h#ll out of it to release the taper. Try lowering the quill fully or use the fine feed to lock it fully raised.
