Later, I remembered seeing a person somewhere (store demo?)
doing letters and numbers with a router, *freehand*. But when
I think about it, it seems just about impossible. Certainly
I myself cannot do anything freehand with a router.
Is it something that can be learned in less than, say, 10 years?
Or is there a trick?

Paste it to the piece of wood you want to route.
Wait for the glue (wallpaper paste) to dry or it will clog up your router.
Follow the letters.
When finished - soak the wood for 20 mins in warm water and rub away the
paper.
Result beautifully routed wording.
Tell your friends it was done freehand!!!
PS - practise on piece of scrap timber first!!!!

Sorry about my bad english .
Now Please don't se this as I just brag ,but Il'l place a photo at the bottom
that show how you can have almost any CNC router "write" any letter.
But I rather ansver the most important question about if it is possible
free-hand to move a router . First you shuld not use a router before you know
the most basic thing ; that if you force a router forverts it will force itself
to one side while the router bit work material in the direction you force it but
behind that there are no material ,so the direction the engine run ,will force
the router the opposite direction.
To complicatet ; then allways think like this ; moving ahead the land allway's
must be on the left side of the router, ------ if you suddenly need to pull the
router against yorself, the land need to be on the opposide side. Now when
there are a safe land the router will stay up along the land edge and this could
be a plank put on with two clamps.
Then all you do as you anyway proberly use a pointet bit, ---- is to somwhere as
calos as you can, place a plank edge, so you can se that when you dive the
router, it will force itself up along the plank edge ,while being moved along
the letter. This mean a lot of re-clamping and a bit trouble with round
letters, but if you get the feel, even free-hand round letters are possible.
If not ---- and please let me echo DB's advise with a few test pieces , you can
mount a round "copy-flange" that most hand held routers can be fittet with ; one
that is a short tube around the router bit. If you saw the letters in as thick
MDF or ply as the copy device allow , this "copy-tube" will fit within the
letters you cut with the jigsaw , and if what I write is not to complicatet ,
you can proberly se ,that you acturly just need one halve of the hollow letter
template , as the natural force of the router, will force the copy tube along
one edge only , ---------- then you just once and for all, need to understand
what direction the router bit will force.
Anyway it's just like with a one proeleeor boat, that when you reverse ,the aft
will swing in one direction ; with the router you use the same force to move the
router very precice, but if you forget that this is how to use a hand held
router, then you are not the one who decide where the bit cut.
The idear about printing are allright, but Il'l hand you a nice trick with that
; in the old day's painters when painting decor and letters ,made a drawing on
stiff paper and then with a needle they punchered a lot of small holes in the
paper where the decor was drawn. Then a rough piece of cloth with chalk powder
would place enough chalk thru each hole ,to transfrer the decor or letters. When
the paper are placed ,you could today use some graffiti spray paint .
Anyway here I go brag about 3D routering my name into my big Stanley plane;
http://makeashorterlink.com/?C67E12231
This was easy with a small Roland 2.5 D CNC. router and can proberly be made in
a lot of different workshops, where there are a 3D Router.

> Hi.
Sorry I forgot to tell a very handy trick ;
If you anyway print the letters and want to use a router with a tube copy device
round the bit , you can offset the letters with a CAD program. This way you can
make very precice router templates , and as hand held routers are ment to be
used with a land or a copy devise and not "free-hand" , you at the same time
find out a very handy way to router whatever you need, by simply offsetting the
distance of the copy device ; this box are made from templates produced this way
,and they fittet with 1/10 mm.

So this work with other issues than just letters.

Yes - this is precisely what I find so hard. I tried some freehand
routing with my first router some years ago, but gave up very
quickly.
There must be something you know that I don't. Which kind of bit
do you use?
Thank you,
Sakari Aaltonen
I think you mean what are called "copy rings" here. But that's
not freehand routing...

A CNC router would certainly be very nice to have...:-)

Knowing the power and the rotasion of the router bit, you can control a router
,if you check not to force the router. Yuo will know how much the router drag
sideverts when moved forverts with this or that much force, ---------- with the
tip of your fingers.
Still holding the bit same place or advancing to slow dull the bit , so driving
,you need where to reach, it's getting there that's the trouble ;))
CNC are very accurate , and like plotters they carry text fonds but they can
also provide a frameset for building the boat for the nameplate ;))

I did something similar by writing the registration number as a
PostScript file and printing it on transparencies, the kind you
use with overhead projectors. I then cut out the black characters
and taped the transparencies to the plate (painted white), then
brushed on black paint through the holes in the transparencies.
This would have worked, had the transparencies been stiffer. As
it was, they *curled* and the edges of the characters ended up uneven.
OK - from a distance (5 meters/yards?) they look all right.
As to sign shops - I feel a homebuilt boat should have homebuilt
registration plates...:-)

You are quite right ; best is to use both hands and make a land the right
side,clamp a stop block ,---------- check the router will go from one end of the
markings to the other , check you tighed the clamps , and do this for each line
in each letter.
Then you either rename the boat ,so there are no round letters or build up the
round letters with small pieces and paint it over after filler ;))
( well , ---- it can be paintet letters even they are routered and a background
with wood around look nice) .
Anyway ; you are right that esp. poverfull routers can acturly be dangarous with
big bits.
And esp. if you don't know the trick about routers ,that they will force
themself left when pushed forverts.
