this may be a dumb question and i may be missing the point entirely but i just got a template guide set and would like to find out if anyone knows of a chart or guide that lists the guide bushing size to use for making holes and then the correct bushing to switch to to make the patch to fit the hole precisely for a particular bit size. i may be making this harder than it is, but without having to calculate each time or use trial and error, it would be nice if someone more experienced already has it written down.

most of the time id be using a 1/8" bit but there might be occasions where id use a 1/2" if i had to remove a lot of material within the hole im making. i have a 1/8", 1/4", 5/16", 1/2" straight cutting bits.

or is there a standard addition or subtraction everyone uses that i dont know about. any help is appreciated. also standard (US) is what i need rather than metric.

excellent bob. exactly what i was looking for. thanks a lot. now if you could just get the US to fully convert to metric it would make life easier for everyone.

Your Welcome mharwell01

" US to fully convert to metric" = that's not going to come about but the free software may help

How refreshing to find someone in the USA asking for metrication. I, and a few others have been pushing the benefits of metric in template guides and cutters for some time, it's not surprising that plunge routing is in it's infancy there, calculating offsets when designing templates in imperial is a nightmare. Another gripe of mine is that most of your routers appear to have small openings, restricting the size of guide. Things will only change when woodworkers start to demand these changes and to realise the benefits, an open mind is required. I'm about to put on my flack jacket!

Hi Harry

I'm going to disagree with you on one point, almost all routers have a big opening it's the bottom base plate (black plate the norm) that's in error so to say but that's a easy fix if someones want's to use the big bushing, but that's the kicker, we in the States can't get the big guide bushing...like the 40mm ones.

And you know what I think of the metic system,, we have a system that works why switch...

Hi Harry,

My Craftsman Pro router has a poor sub plate design, ie., the small opening & you have to use Sears guides. (Which is why I love OP's plates, adversity

). However, as you very well know, the Makita's have a decent sized hole even in the sub plate. It's usually the sub plate that screws things up for routers.

Now, for the metric system. It's as I've said before, I don't know it but, always willing to learn it. Rather people truly realize it or not but, the U.S. is slowly changing over to metric. It's just a gradual change.

Just my thoughts.

**bobj3** · 03-14-2008, 04:57 PM

I love to pull Harry's chain,, if anyone pop's the metric sub. up Harry's off and running

LOL LOL hahahahaha You know I'm only joking Harry

Harry, I am with you all the way for metrification in the US. We were going to start a campaign to do just that earlier.

I have been occupied with other concerns in recent months which is why I have not been more outspoken on the subject. I hope these other issues can be resolved in the next two months.

mftha · 03-18-2008, 04:21 PM

mharwell01,

Where are my manners? You raise a point very close to my heart (look at some of the previous postings), HarrySin answers with great enthusiasm, and I respond to HarrySin. I fully agree with you that the U.S. should join the rest of the world and start using the metric system. Perhaps a new thread needs to be started on how we can integrate the metric system into our common interests.

I have a Makita router but I use the Oak Park base plates and the Oak Park template guides. HarrySin is correct that there is no way to use a 40 mm guide. I do wish there were larger template guides and base plates to accommodate them available. What I really want to see is an Oak Park base plate with 10 cm (4 in) opening and template guides and inserts available to reduce the opening to appropriate sizes.
