Default Routing regular dado in small profile stock

Hi

I making a rack where the framing is 15mm x 20mm. There are 6 pieces of framing, each about 500mm long. I have to route a series of shallow (2mm) 10mm wide slots in the framing - with 10mm between each slot. I've calculated there are about 140 slots that need to be cut!!

What's the best way to do this? I assume with the router in handheld mode, with an custom made base plate that has a 10mm wide guide strip attached to the underside, leaving a 10mm gap between edge of the 10mm bit and the guide strip?

I also have a router table - but can't see how that can be used in this instance.

Matthew

PS - have attached a pic that may help explain it. The length of the framing is not to scale - however the height/depth of slot/spacing of slot is.

Hi Matt - had to think on this one a bit as I was kinda confused as to which way the dados are running. As I understand it, you need 6 pieces 15mm thick, 20 mm wide and 500 mm long with the dados running across the 20 mm direction?
If that's the case I would start with a piece 120+mm wide and 500 mm long. Run the dados across the 120mm dimension and rip to the 20mm end product. Don't forget to adjust for saw kerf.

The problem with experience is I usually get it immediately after I need it.

Hi John

Sorry for the confusion - you're right though, the dados are running across the 20mm wide bit - so are 10mm across, 20mm long, and 2mm deep. Good idea with the wide plank - and then ripping that - hadn't though of that.
