Default Bushings or Bearings

Just starting out with a router and I will be using templates. I will be making my own templates so I can make them the size I want to with either using bushings or using bits with bearings.
I"m wondering what you all prefer to use if you have the choice? I have read some ppl dont like the bearing bits because they (bearings) end up failing and ruining thier work. Please let me know what you think to help me decide what route to go.

Thanks

Hi


Just my 2 cents, I like the bearing on the bits they are always dead on unlike the guides that you must off set them to use them right, I always check the bearing b/4 I use them ,the little screws will come free easy BUT sometimes you can't find the bit with a bearing on it so the guides come into play at that point I use the 1 1/2" guides most of the time that gives me bit more room for the bit inside the guide plus more room for the chips to come out, but I also use the off set rings to use the same template for many types of jobs...

You may say what are Off Set rings you can see them in my uploads..

Just a side note****so many have errors with the dovetail jigs that's because they use the guides ,if they use the bearing on the bit most of the errors will not come into play or to say the joints will be cut right on the button,,the error with the guides they MUST be dead on with the shank of the dovetail bit and most don't take the time to do that, it just takes a little bit off center and the joints will not fit right..

Hi, and welcome to our little corner of the 'net.

As for bushings or bearings, it all depends on what you're doing. Bearings can certainly fail, but it doesn't happen that often. You just have to periodically clean them so they don't seize up. Most, not all, template routing is done with guide bushings.

I'm really wanting to go with the bearing bits. I will be making some guitar templates. When I use them , I will drill out most of the wood (on the guitar) with a drill bit and then router out the rest to get a nice clean cut.

Im just getting used to using the bushings but on my current project I used both. Following a Southwest pattern with a bearing bit halfway thru the stock I removed the template ,added a bushing with the same radius and a straight bit to cut all the way
thru. leaving a "shadow" image. both seemed to work fine for me

.I do have some questions on how I did what I did but I'll start my own post.

The beauty of template guides is that by changing sizes and/or bit size on a project a very large variety of off-sets can be created. A whole new range of projects can be designed.

Another point worth mentioning is when you use a template and guide bushing you only need one bit. Depending on the project you might need both a top bearing bit and a bottom bearing bit. Using a bit with a guide bushing only requires changing the depth of your cut. Bearing guided bits are at fixed positions so you would have to shim or adjust your template. You can't plunge cut with bearing guided bits. If you are using bearing guided bits with soft wood the bearing often leaves a mark along its path which may require light sanding. Bearing guided bits are very useful for edge trimming but for internal/plunge work not the best choice. The bottom line is you will most likely end up needing both.

Bearings, if kept clean, have always worked best for me.

What sizes of template guides do you have?

I am just learning about template routing and guide bushings as well. I have to admit, I get confused about this easily and have probably shied away from learning more. I currently use bearing guides bits with success but I know next to nothing about guide bushing and template routing....is there a suggested thread on this forum that would be helpful for me to study in that regard?

Thank you
