Cherryville Chuck Hi Safety Guy and welcome. Even the manufacturers say Do not use handheld once a bit goes over about 2.5 inches or about 60 mm.

harrysin This is of course a VERY old thread but for anyone still following it, raised panels should not be routed by hand held router, but on a router table or shaper. Even on a router table I don't feel happy with a huge block of steel whizzing round at speed. As I mentioned in an earlier post, a VERTICAL raised panel bit is my choice and they are available in several profiles.

safetyguy I have a Makita 3612 BR that I use with large panel bits. First off you will need to use an accessory speed controller to be able to swing these large bits at a slower and safe speed. Then, remove the plastic base from the router base. Make a home made base of adequate thickness (1/4", 1/2', or 3/4" Plywood or tempered Masonite. Be sure to cut the opening big enough to give at least an eighth inch clearance between the bit and your home made base. Attach this new base to the aluminum router base with longer screws. This has been working for me for years.
P.S. making your base elongated and attaching a handle, like you see in some catalogs, will give you greater control. Feed slowly and be careful, as these large bits are only supposed to be used in a router table. But this method works well when you cannot use a table.

harrysin Dave, you certainly can do that but as has been suggested by I think bobj3, for safety, a spacer should be fitted to prevent the router from slipping down and opening up the hole in the base should the lock lever fail to grip.

dave142 oh right.. thanks for explaining that.
I don't know why you couldn't fully plunge the router in, then fit the cutter but I am sure there is a reason or this thread would not exist.

cbsjoez1935 Dave,

Don't dispair. The terminology of 2-3/4" opening refers to the hole in your baseplate, where the router bit slips through. Obviously, a 3-1/4" panel bit is not going to fit through a 2-3/4" opening. You are going to have to obtain or make another base plate for your router that has an opening large enough for the router bit to fit through.

The router in question has a 2 3/4" opening and increasing this to accommodate a 3 1/2" cutter
sorry for a very dumb question but I don't even get what... 2 3/4 opening is. Does that mean the hole for the router bit to go in? Im confused, its inches we are talking?

I'm not surprised Dave that the thread puzzled you
I don't tend to understand much of the technical stuff on these threads, if I try and make something I usually end up just trying to work out my own way, because I don't get it. lol

harrysin This is the first that I have seen of this post and I am amazed that the definitive advice to buy a vertical cutter was not given, only suggested by one member. The router in question has a 2 3/4" opening and increasing this to accommodate a 3 1/2" cutter would remove the ability to use template guides apart from the time and effort required for an unknown result.
I'm not surprised Dave that the thread puzzled you.

dave142 I know this topic is old now, but can someone explain this thread to me (a novice)

Does any one know of any after market Base replacment for the Older Makita 3 1/4 Hp router Model 3612BR that would allow me to use larger 3.5" raised panel bits?
I have the same router. What is the problem with 3.5" raised bits? they don't fit in the 1/2" collet? Why do you need a different base to use these?
Thanks for helping.

Yup I know.
I am just getting back into woodworking after being away from it for along time.
Still trying to get my shop built.
So far still waiting for Geo-study that the city makes us do now after a house caved into an old mine shaft.
All I have so far is the plans have been drawn up for a 20'x36' 10' tall inside walls.
At this point I have to set things outside to do anything as I speak I have a Drill press standing behind me in my computer room among many other tools.
Our west coast weather does not give us many dry days during the winter.
Soon I keep telling myself.
