Stuck Morse Taper - new to this!

[JonnyB]

I’m new to this forum and fairly new to milling having just bought my first one recently. It’s a new 350W Mini Mill by Osaki, I guess it’s just a rebrand of the Chinese made model, and exactly the same as the Clarke CMD300. It’s new and unused with all the original ear wax still on it but I bought it off someone on eBay. Looked all fine but now I have started to try to use it, I’ve noticed the Morse taper attachment is really stuck in the female shank (or whatever you call it). I’ve tried getting it out the normal way - releasing the draw bar and give it a hit (I actually damaged a couple threads doing that so have learned not to do that but put a 10mm steel rod and hit that instead). No luck. I’ve tried heating the female part of the Morse taper with a micro butane torch and tried hitting it again - still no luck (although I don’t think I managed to get it that hot, so have ordered a proper propane torch). Now I’m wondering if I am missing anything (a locked thread or something I should know about), or where I will need to dismantle the drive and attempt to dismantle with a hydraulic press or something?!
Any ideas? I tried to cold spray (with an upside down air duster can) the drill taper but it had already hot from conducting a lot of heat from the butane torch and the condensed gas was just vaporizing on contact without managing to cool it down at all.

I’m guessing I need to put a lot more heat into the female shank because it probably barely 100 deg C or so, but it makes sense that I heat the outer and cool the inner parts but they are contacted very well so seems tricky to do.

Has this happened to you before? Any tricks you can recommend? Better to torch and hammer or dismantle and press it out?

Thanks for the help
