Step 5Attaching the Wheels
iImage Information

First, measure 2 1/2 Inches from the side of the rollers to the end of the metal rod, cut there with a hacksaw. Repeat on each axle until they are all done. Then put the spacers on if they came, if not then it is not a big deal. Then put the wheel on, then pound the metal end cap on with a hammer making sure you brace the other end so you don't just push the axle through. Do this do every one then put the PVC-wood combo under each side and depending on the size of your wheels the axle may touch your PVC, mine did. I ran the PVC-wood combo through the table saw with the guide on and almost ruined the PVC by cutting it too shallow. SO DO NOT USE THE GUIDE WHEN MAKING THE PVC MORE SHALLOW. Do it by hand and only shave off a small amount. If you made a perfect first split then you shouldn't have to worry about it.
Good and simple design - I like it.
