I used bearings on both ends. Here is a picture of the end nearest to the motor. Its very cost effective and simple. The rollerblade bearings are cheap and since they are deep groove they work well for thrust.
I counterbored the MDF the same diameter as the bearings and just pressed them in. I just shot a couple of screws in tight next to the bearings and used the heads to hold the bearings in place. Real simple, yet effective.
I prefer to make the mounting block adjustable, not the bearing in the block. |
