Hi did as advised its not the tail stock the headstock adapter looks like it has to many groves so is not actually fitting. I've wasted over 170 quid so far and feel like chucking it in
Unfortunately, this is something that many find when they buy the cheaper Chinese made machines. No one likes to waste money but you will find that if you stick with it the rewards are great and I am not talking about money that can be made selling what you make.
Try to sell what machine you have and buy a better quality one and you will find the experience much better and enjoyable.
I know this is not what you may want to hear.
If you do go down this route ask as many questions about machines and accessories before committing to a new or second-hand equipment
