Hi Ace
Many router guides can be made by you and are better than the ones you can buy..
That maybe why the company didn't make it, many router users make one or two because they are easy to make and are more accurate than the ones that come with the router kits..or you can buy.
If you do a search on the forum you will see many shop made ones...
If you don't find any just ask and one of the members will give you a hand finding one or two..
