It is impossible to say what size of motors you require without giving details re your machine. It might be a good idea to start your own build log to keep all the questions in one place.

Clives 100% correct but it's also 95% chance they won't be suitable for few reasons. First reason high chance they will be high inductance motors which mean you'll need expensive high voltage drives.
Second reason is they'll be all wrong for your machine unless large or heavy load to move.

Jo be careful you have enough epoxy because it's proper ball ache if you run short. However I know 1ltr should be enough for machine your size so shouldn't have any trouble.
Really make sure you seal it well because it's amazing how epoxy finds leaks and they don't always appear instantly so keep checking and be ready to make repairs. Putty is handy stuff to seal quickly.
