This is my latest creation. It is long past due. I have been using a real crude router table I threw together a few years ago. As in many of my projects I wait for the parts to come together to avoid high costs.
The top on this is 1.25” thick clear lexan bullet resistant glass. It was salvaged from a convenience store that was torn down. The piece I used was too scratched up to use for much anything else and I am sure it will get scratched more but the surface is hard flat and smooth. The frame is laminated plywood half lapped and glued together on the joints.
I made many parts on the machine from HDPC plastic. I buy it from a local manufacture as scrap they cant use. This is great stuff for building machines, it cuts and machines very well.
In playing with building machines the last few years I found that wood on wood slides are not practical if you want accuracy and durability. Humidity can make it tight one day and loose days later. I have also used bushings on rods but I find that although they are smooth the clearance needed for them to slide can translate into looseness at the router bit.
So what I developed was, I used 6 roller bearings running in a grove under pressure, 3 on each side. This works very well. It is smooth and there is no play what so ever at the bit. It is driven by threaded rod with bevel gears I got from etrailer.com.
The plunge is foot operated and is a separate mechanism than the router lift crank itself.

If you can view the video things are explained in more detail.

This is a great build Mark, I like your unique innovations for the lift and plunge features. Do you have a positive locking feature after setting the bit height?

Lee,
I do not have a lock on the height adjustment. It was something I was contemplating and can be easily done. But being held up by threaded rod and pressure from the bevel gears it doesnt move. I tested it by letting it run for some time to see if vibration would move it and it didn’t. Time will tell on that if it becomes an issue I will lnstall one.

Great router table. Really like the clear top. Thanks for the info about the right angle gears. I have been looking for cheaper priced bevel gears for a project.

Very cool. Are you the same guy who built a crosscut sled from thick acrylic?
