DIY Free Motion Cycling Rollers

Step 4 Drill Holes for the Axle

This is pretty simple. Whatever the size of your metal rod is, that is the size drill bit you will use. My rollers had 6 legs that I drilled into, you may have to improvise if yours are different. I know of some with only 4 legs, I would say that wherever the rollers contact the ground, put an axle. Just drill holes for the rod in two or three spots on both sides, making sure the holes opposite each other are in the exact same position, so the axle is not crooked. Now make sure the belt that spins the rollers is in the position it needs to be to function. I made the stupid mistake of not doing this and I had to take apart the assembly after it was complete. Then slide the axle through, you should have to bang it through with a mallet, don't use a metal hammer unless that's all you have, it will make it difficult for the metal cap placement. Also, the axle is not supposed to spin.
