Marking out the holes is the easy bit, getting the drill to drill dead centre of
those marked holes is the hard bit! Especially if you're not using a centre
punch.
I'll tell you what I intend to do, and it does seem an awful lot of work just to
put the sill letters on, but I'm anal about this kind of thing (comes from being
a Graphic Designer *g*) and unless they're 'absolutely right' I'll never be
happy.
It's interesting actually if you look in Grahame Bristow's excellent book -
'Restoring Midgets and Sprites, an enthusiasts guide' by Brooklands books on
page 205, he actually goes through the procedure for putting on these letters.
He actually had a printed up template to use, AND HE STILL GOT THEM TO LOOK
CROOKED! lol
I'm going to actually draw out the correct position of the holes on a scrap
piece of steel. I'll centre punch them and then drill a pilot hole with a fairly
small drill bit - probably about 2mm. I'll then use this as a template for
drilling the holes through onto another scrap piece of steel. The advantage of
using small pilot holes is, you can use it as an exact template for drilling
through - because the holes are so small, theres little room for the drill bit to
move as it drills through - getting an exact replica. Once I'm happy the holes
are in the correct position - I'll drill through with the correct size drill bit for
the little rubber tubes.
If I can't get the position correct using this procedure, I'll cut up the steel
template and position the letters individually and when they're correct, tack
weld them together forming the correct template.
As I said, a lot of work, but its so easy to get this wrong and the letters look
horrible if they're crooked.
