Joe I did not have any shrink problems at the ends on mine but do put the effort in to stop any leaks you will be surprised how easy it is to get one, a small bead of silicone is the key

I sealed my moats by running a small amount of epoxy along the gap first. Small amount and it doesn't run through but will cure in the gap and stop it leaking when the full depth goes in a day or two later.

been looking at nema 34 stepper motors online,,,,,would they be suitable ?,,,,,i plan to be machining sheet material like mdf,,,melamine,,,oak and ash ect.. also i see the motors are avalable with differant holding torque......would the higher values be advisable.

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.
