Terry,
Unfortunately, if you are not going to spiral wrap the rod, on a rod that light, the line will more than likely touch the blank somewhere. The only thing you can do is just try to space the guides in such a manner that the line touches the blank somewhat evenly from guide to guide. In other words, space the guides so that the line touches the blank the same between each guide(assuming it touches the blank in more than one place).
As far as the winding check goes, if you ream carefully, you don't need one. What I do now instead of placing a rubber or metal check, is to do a epoxy winding check. All I do is get some five minute epoxy and mix up a small batch and mix in just a tad of black Testors model paint with the tip of a tooth pic. You will want to let the paint sit for a while ( it may take a day or so) with out disturbing it so that the pigment will settle out and the solvent float to the top and pour as much solvent off as you can prior to using. Chuck your rod up in your dryer and elevate the other end a few inches and get the rod turning. Make sure and have this ready before mixing up your epoxy! As the rod is turning, take your toothpick and start applying the epoxy to the rod where the grip and the cork meet and use the tip of the toothpick to manipulate the epoxy as needed. Keep adding it as you go...building it up as needed. I usually shoot for about a 45degree angle ramp from the rod to the cork. After I am satisfied that I don't need to add anymore epoxy, I take a coffee filter or paper towel moistened with alcohol and fold an edge in it and lower it to the edge of the ramp and blank to create a smooth edge. Then, just let it turn 'till it sets up. It can sometimes be difficult to get a perfect edge, so I usually wrap my hook keeper wrap close enough that the wrap goes all the way to the check and hides any imperfections. The thing to remember is you are dealing with five minute epoxy, so work fast. If you don't have a dryer motor, you probably ought to get one. They can be bought on e-bay pretty cheap. I Have a 4rpm for drying and a 44rpm for drying, and applying thread finish. I feel the 44rpm works the best for making the epoxy check. Hope this helps.
