Am in the progess of rebuiding my sunroom and presently have a plan for making a French door for the main entrance.  However, am wanting to make 3 sliding glass doors on front of the sunroom so we can open it up to the out door.  So what I am wanting is how to make the three doors slide.  The wood will be red oak that has been aired dryed and will be ready this summer and I have the abiity to mill the wood to size.  Also will be adding glazed glass with argon gas in between, but the problem lies with making the doors slide   Have e-mail several handmade Shoji door makers and am beginng to get some feedback from them.  So am looking for more information  from other woodworkers that may have tried this or maybe have some suggestions.  Am planning to start late summer or early fall so I have the time.
