Here is a quick reference to different types of guide bushings.

Top left: Old style Bosch. Installed by removing the bottom plate of the router.
Bottom left: New Quick change style Bosch. Installed by dropping into place and sliding a lever. Note the quick change adapter with a PC style bushing installed.
Bottom center: Typical Porter Cable base plate with bushing installed.
Bottom near right: PC style bushing.
Bottom far right: Rousseau mounting plate installation bushing. Note the removeable top ring locked in place with an allen screw. Guided by the template with a straight cutting bit installed; removes the main cut out for the router. Removing the top ring reveals a smaller guide used for cutting the lip that supports the plate.
Top right: Typical Craftsman router with guide bushing. Bushing is plastic and held in place with 3 screws.

Template guides listed will restrict the size of the cutter that can be used There is a need to purchase a 40mm Guide which will give a greater range of cutters that can be used and not only straight cutters.

Mike has kindly emailed me to insert a sample of what I mean. In this instance the guide is 40mm and the cutter is 25mm in diameter

At this time 40mm guide bushings are still not available in North America.

Looks like 40mm is about 1 5/8"...

I don't think I've seen one that large!!

Now what?!

**Mike** · 11-16-2006, 10:53 AM

The only way to get the 40 MM guide bushing in North America is to order it and the matching base plate from Trend in the U.K. I have asked Trend N.A. to start carrying this product but so far no response.

Mike here is the reply I got from Trend

Dear Tom

Thanks for the follow up email. The 40mm guide bush is quite a slow mover in the UK which is a shame, as it is very useful.

I will mention you comment about the 40mm guide bush and it uses for the USA market to our USA office.

Thank you

Regards

Hi Tom

What is the big deal with a 40mm brass guide when most routers can't use it without a new base plate, I see Bob & Rick are using 1 1/2" one on some of the fixtures, what can be done with one that is 40mm (1 5/8" ) that you can't do with one that's 1 1/2" I still use the 1" one and it works for most of the fixtures I make or use.

Most bits that get that big should not be used on a plunge/hand held router anyway I think or I'm I wrong , most the ads I see, say to be used on a table router Only when the big gets
1 1/2" bigger, that's alot of steel spining under the router plate and if it gets hung up best hold on.

But I'm just asking

Thanks Bob for asking the questions:
To start all my guides are steel though I think brass is better. Most routers are unable to use 40mm without a new base plate (Except Makita and Hitachi in Australia.
I agree there is very little difference in the two guides you mentioned above and I am sure I could have used the smaller one but the 40mm guide is a regular size here in Australia.
You mention that you manage to complete all your projects or processes with the 1" (25mm) guide One of the reasons for the 40mm is there is a greater number of cutters that can be used 1" will restrict the number.
Another reason for the 40mm guide is that the cutter is usually visible when doing the process. (I would use the 40mm guide with the 2-6mm cutters not just for the larger cutters)
There is less chance of the cutter overheating say a 12mm cutter in a 16mm guide. also the 'swarf' will dissipate more readily using the 40mm.
Finally from a safety point of view: when using small cutters 1/4" they are usually short in length therefore sometimes difficult to reach the required depth because the collet (Chuck) will rub on the top of the guide wherar the 40mm guide will allow the chuck to penetrate through with safety.
Most larger cutters should not be used in a router without variable speed control
Tom
Thanks again for asking the questions

**bobj3** · 01-09-2007, 08:18 PM

Thanks Tom that helped

Most of the routers I have the collet (chuck) nuts are 22mm and some are 24mm, do you have routers that have collet nuts bigger than that ,if so what kind. ?

One more thing do you use 1 1/2" bits or bigger in your hand held router with a speed control, if so is it safe ?, with a steel guide or do you use the bearing on the bit ? as a guide .
I have not had the guts to try it,even at low speeds

no pain no grain BUT this one I will let others try it I think

Thanks
Bj
