When using a template, it is often suggested that one use double-sided tape
to affix the two pieces together. At the end of the operation, it is
assumed that they are easily separated without leaving patches of tape on
either surface. What is the name of tape used for routing applications
(e.g. carpet tape, mounting tape or whatever) and where does one buy it?
I've seen 3M's mounting tape and carpet tape at Walmart, but those items do
not appear to be easily removed.
Hopefully, it's not only available in wood working stores.
Carpet outlets/stores. Try to find the cloth backed tape which is stronger
and tends to hold better. For light duty projects, the standard borg carpet
tape (vinyl backed) works okay but for heavier duty routing - get the good
I just did this on Saturday night with about 12 pieces (half MDF half
pine). I used the carpet tape found at Home Depot in the isle with
all the different tapes (near the paint mixing station in mine). One
thing I found is that I didn't need to use a whole lot. I had a
template that was curved (like a slow S) and about 13" long. I used 2
pieces of tape about 3/4" x 1/2" in size (I just cut a 3/4" or so long
piece of 1" tape and cut it in half. Then I stuck it to the
workpiece, used a razor to pull the white paper off and then stuck the
template on top.
Check to see if you can push the pieces off each other in the
direction your rotor bearing will apply pressure as well. A couple of
times I didn't make the pieces quite big enough and it pushed the
template at the end of the cut and I ended up with a nice little
gouge. But that won't matter it'll hide in a tongue/groove joint
I also put them in about 1-1/2" to 2" from the ends so that when I was
done I could pull the template up enough to pull it apart (my template
was 1/2" MDF).
Once pulled apart the tape usually was still on the workpiece and I
just pulled it up with my fingernail (you could use the razor again,
but since I'm distressing/painting these, I didn't care about extra
marks from my fingernail).
Good luck, and if you're feeding this by hand on a table, watch that
you use the right feed direction (almost sucked my hand into a groove
bit one time when it sucked the wood right into the bit as I started
to feed it -- still makes me shiver to think about it -- what a
blessed novice I was!!).
Just carpet tape, as you've already named. Get it at Wal-MART, or at
Home Depot, or any other hardware store. It comes off easy enough,
after a little coaxing. And I don't think that it leaves any
