Title: Router bit for t-molding
Post by: Fitznab on June 28, 2009, 01:22:58 pm: Hello All,

First off I have NO woodworking experience at all.

I have tried to find a slot router bit to make the slot for the t molding. Depending on the source, I need a 3/32" or 1/16" slot bit, does it matter which?

I cannot find anything smaller then 1/4". Any suggestions on a quality online site?

If you are buying from t-moulding.com they show the spine width and tell you the reccommended cutter width. They also sell the correct cutters and arbours which tend to be quality whiteside bits.

I would reccommed buying from t-moulding.com I have ordered from them a few times and shipping has been fast, even across here to the UK.

You may be able to buy the cutters etc slightly cheaper elsewhere (although they are much more expensive over here in the UK) but once you take shipping from multiple places into account you may as well just buy it from one place.

I purchased the exact sized router bit and the correct sized t-molding. Everything was going well until I went to put the t-molding into place. Granted, I'm a novice at best, but when I was pushing in the t-molding, it was so snug that it pushed the sides of the MDF outward causing a bulge (thankfully it was a prototype :) ). Anyhow, it's just something to be aware of.

I purchased my router bit and the ball bearing sleeve from Rockler Woodworking. Fairly good price. I think I found it at Amazon.com.

Was it 1/2" MDF? I could see that happening with 1/2" but if it was 3/4" it shouldn't have happened unless your slot was WAY too thin. I use a 1/16" slot cutter.

+1 here and you cant beat the price.

Just keep in mind that not all t-moulding has the same spine width. The 5/8" black/chrome pin stripe moulding for example needs a 3/32" slot.

As javeryh said your slot must be too thin. You can set your cutter at center height and then offset it slightly and run the slot cutter down the slot again from both sides of the MDF. This will give you a slightly wider slot whilst still being central. Adjust the cutter height gradually and you should be able to get a nice fitting slot.
