Question Routing MDF

I'm cheap! I have several projects where I have used old sink cutouts from a local cabinet shop. They throw them in the dumpster so I rescue them and give them a good home. I build custom fishing rods and am building a new building table- hard to build a 7 ft. rod on a 6 ft. table. Part of the uprights to hold the rod are pieces of countertop. I want to make a dado in a piece about 18 inches long, down the center to straddle Incra T-Track. My router has a 3/8 straight bit in it; several shallow passes? Is this too much for the router or should I run it through the table saw a few times; don't have a dado blade....yet. What about the MDF dulling the bit? Bit is from a Ryobi set I got at Lowe's.
I am actually getting around to using the router! Bought a Kreg router table at Woodcraft a while back. Have a project that SWMBO keeps asking about- jewelry rack for the wall. Plain wood that will be stained.
Your advice is most welcome. Thanks!

John T.

MDF dulls everything, John. Honing the carbide before/after should be a snap with the straight bit.
There's a bazillion references in the forum to the diamond grit credit cards...

No, but I was counting on you to have at least one...

Guys, thanks for the links. I saved them as Favorites for future reference. Stick, our local Woodcraft store is having a sale tomorrow. I'll check with them to see what they have for my needs.

Making a groove or two with saw will make a huge difference. I've found it can extend the life of a bit by up to 3x because their is less material, more cooling air, and a path for chips to escape. You will also notice that the router works less

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Chances are that the material is not MDF it is more likely particle board, this is what they use for laminate. As to your question you could easily do it with the router and not worry about the bit. After all you are only making a very small groove and not using it for production work. Even if it was MDF I am using the same raised panel bit that I bought over 25 years ago from MLCS and have made over 60 doors with the set. One job alone was 27 doors. If you don't use the straight bit for grooving what are you going to use it for? To me straight bits are expendables, you can buy a set of four straight bits for $23.95. Given the limits of a straight bit I would be willing to bet that the set would last the average person a life time.

I was going to cut a dado a bit over 3/4 in. wide to straddle an Incra T-Track. I think I might just stay with multiple passes on the TS and save the bit for other projects. This piece will only be about 4 inches long. Will cut a longer piece with a push thingy to keep the fingers away rom the blade.

From what I experienced, when working with either MDF or particle board donning a good fitting and effective dust mask is necessary! Your sinuses will thank you.

First off; I try to NEVER use MDF if at all possible. I hate that crap with a passion. A good piece of plywood will certainly do a much better job for ANYTHING I could dream up. There is NO MDF in anything I own or make. That's a personal preference!
