Title: need help with terminoligy
Post by: Dawie on July 03, 2010, 04:52:00 pm

Hi everybody,
 I order most of my pattern books on internet and they are great. Just now and again I have difficulty in figuring out exactly what they mean. Just received agreat book on puzzles. There's a description on how to make a wooden vault inspired by the Da Vinci Code. Here comes the terms I do not fully grasp:
Forstner bit
Rabbet "Add a rabbet around each ring" (Figured got something to do with routing)
Thanks for any help. Looking at the pattern again it is at this moment a bit out of my league, but I will get there.
David

 David,

  Try the following web page and you'll see what they look like.

  They are specially made up bits to cut very clean sided holes and you can even use them to cut a hole that is not all the way inside the board.

  A rabbett is like you imagine. think of an "L" cut around the outside edge of a board. You mention "ring" in your pattern so you would be right in that it would take a router to do that. On a board you can do the same with a router, or table saw. With a table saw you can use either a regular blade,or better yet a set of dado blades.

A forstner bit is for drilling holes, there are 2 types 1 for end grain boring and 1 for long grain boring and they come from 6mls to 75ml or even larger, they are expensive
I think a rabbiter is a router bit.
A piece of useless info on forstner bit a passed member of our club, [Frank Forstner] his uncle invented that bit

Hey David, A forstner bit is designed to cut a clean flat hole. They come in many sizes from 1/4" up to 31/2".
A rabbet is a grove on the edge of a board.

Thanks you guys. Now I know what I am looking for when I eventaully get up the courage to make it. At least I have the right routerbit. Will have to save up for the forstner though. I liked the bit of extra info Jimbo.
Have  a great 4th of July you guys in the USA.
