Hi,
Does anyone have experience routing edges of 3/4" MDF to insert T molding?
I am specifically looking to try this for my control panel edging.
Do you use a router?
Should you use a dremel tool instead?
How to maintain a straight/even cut?
Pictures/examples?
Where is a good place to get T-Molding?
Are there different types of T-Molding which work better?
Any pointers is appreciated.

Yes you should use a router and NOT a dremel. You will need a router and a 1/16" slot cutting bit for it. Basically you just put the bit in the router, put the router on your MDF, you can then adjust where the slot cutter will cut into the MDF, you can eyeball it (like I did) to the middle or measure and make the adjustment. After you've made your adjustments you just tighted down the knobs on the router, turn it on and start making the cuts.
Tips:
-The router cuts best going left to right or right to left, read the instructions to know which way is best and don't go the other way.
-Measure twice before cutting and make sure all the adjustment screws are tight before you start
-Make sure the MDF piece is secured to something before you start and make sure to use 2 hands on the router
-Wear eye protection and a mask.
-Cut the slot outside, that MDF dust goes everywhere and is nasty
-BE SAFE
Honestly, it's very easy to use the router to cut the slot. If you don't have a router you can probably rent one at a local hardware store.
Just do a Google search for T Molding, check out Ebay, look here in the buy and sell section. The site mentioned above has a good selection but I found mine for much less someone had on sale here in this site. I don't think one works better over the other.
Good luck, honestly I think you'll be surprised how easy this step is.
