So, Fall is coming and I wanted to make a few more gliders, I usually trace a shape out from a template, rough cut it on the bandsaw, then sand it down to final size. But after watching some guys on Youtube build some pretty interesting stuff using template routing, I thought I'd give it a go. I thought I'd drop this in the Glider thread, but it really applies to any shape that is not round. Any "handcarve" blank can be duplicated this way, if you have a router table, and a flushcut router bit.
So, it starts with making a template of any shape that you're happy with, I just happened to have some glider templates on hand, so I used them. The point of this is to be able to make pretty exact copies of any shape you're working on to remove that variable. So I take the template and mark out some pieces to rough out with the bandsaw.
The idea is to make your cuts close to the line, so your router bit doesn't need to work too hard. Take some double sided tape and stick your template onto the rough blank.
It doesn't take a lot of tape to hold the 2 pieces firmly together. Too much and you will struggle to get them apart. Next picture shows the bit with a double row bearing installed, the bearings follow the template, and the cutter does it's thing.
The video shows how I do the fun part, I know some folks will not like my fingers being close to the cutter, but rest assured, I am never pushing towards the cutter, mostly pushing down to minimize any chatter. If you ever feel uncomfortable making a cut with a power tool, DON'T DO IT!! In the video I'm pushing down, and pulling the piece against the direction of the cutter's rotation. I've tried using push blocks, and felt I gave up control, so this is how I do it.
Template Routing
What you're left with is an exact copy of your template. I run a few more pieces the same way, switch to a smaller template and do a few more pieces, and wind up with a batch that's ready for a roundover. Once they are rounded over, start sanding, and drill some holes.
