routing crosswise on a long board

[pistonengine]

Hey all,
I'm looking to route rabbets crosswise on a board, as shown in this picture. I realize the ends will be circular, which is OK. The problem I'm anticipating it keeping the router straight. I don't have a router table available (nor a tablesaw with a dado blade). Any ideas?

Have a look on YouTube or Google -Router/ Dado Jigs

Easy, clamp a straight edge to the timber that you can run the router along and stop the cut by eye.

There are plenty of jigs you can make; look up dado/trenching/grooving jigs online. We have a forum member called "Template Tom" who will no doubt soon reply to your query with links to You-Tube; he appears to have hundreds of instructional videos that he often provides links to; or you could just look him up.

Thanks Chief But I do not have a video of the process on you tube but I have a photo (Drawing) of what I do to produce the dados All that is required is to clamp the material in place This is my smaller version suitable for narrow boards. There is a larger version capable of routing 400mm wide boards

There is a very simple jig I use in this article. It is exactly what you want:

Thanks all. Looks like the solution was very simple, indeed! I'm a little embarrassed I had to ask...

An oldie [now] but still used when necessary. It allows for perfectly parallel or tapered trenches.

Can use the jig with the 2 rails if you need to go wider than the bit size you have or can be used as a single rail as in pix 3 of the first post in the link below.

Hope it helps and welcome to the forum.

No way, pistonengine. The only silly question is the one that you did not ask.

That jig as suggested by Tom and Derek is incredibly versatile and worth building well. It will be used frequently. If the router fits snugly between the guide rails - moves freely but no "wobble" - then you will get a really good output.

I have also used it with a dovetail bit in the router to cut sliding dovetails for extensive walls of bookcases.

I should also have added that I use a 40mm template guide to guide the router cutter ans as Graeme said dovetails can also be cut
