1/16 inch or 5/64 inch slot cutter?

[BobA]

I noticed that the slot cutter from t-molding.com is listed as a .075 inch.    

When I convert 1/16 I get .0625
When I convert 5/64 I get .078125

I found both of these in a Canadian catalog.

Does anyone have any preference on which one to use?  I assume that this may vary a bit with the t-molding but since t-molding.com sells a .075 I would like to get as close as possible to that size.  Currently I am leaning in favour of the 5/64 but I would appreciate any comments.

This is what I've found...  I purchased 3/4" t-molding from t-molding.com and I used a 1/16" slot cutter.  If you don't paint the raw edge at all and install the t-molding, the t-molding taps in smooth as can be.  If you primer or paint the edge after you cut the slot, then the 1/16" slot is a tad too small and I had to use a razor knife to go back and scrape out every bit of primer in the slot to install the t-molding.  If I didn't, the spline would tend to fold over rather than tap in.

Myself, I wouldn't pay the extra $$ for the .075" slot cutter, especially if you can pick up a 5/64" for the same price as a 1/16".  I haven't used a 5/64" slot, but I bet it would work just fine.  1/16" is very tight and will hold the t-molding forever, but I'm sure the 5/64" will well, too.

I would go with the 5/64 it should work fine.
If it's a little loose you can allways use a little hot glue.
If you use the smaller bit it may be too tight and it will give you troubles installing it.
I got  my  T-molding from rockler and I used the 1/16 slot cutter. My molding was 3/4"

Ok thanks, sounds like 5/64 is the way to go.   Will have to see if they have stock.
