Hi Tal, welcome. Where are you from?

1. I've been happy with about 15mm between strings. The common lumber used for 3-string necks in the USA is 38mm wide, so that leaves a few mm on each side of the outer strings.
2. Those boxes will work.
3. I like the stewmac calculator: http://www.stewmac.com/FretCalculator

Hi thnx man!
Im from Israel.

do you have a CBG print pattern? so I can just put on the neck.
And, what kind of scale length do you recommend? gibson..?
again I dont know what Variables to enter to the equation -scale length, electric/acoustic.

thnx.

This site will print you a PDF pattern. You don't need to download it, it works over the web. You can fool with the measurements for string width and spacing if you like, or just use it for fret spacing and ignore the rest.

Just looked at this scale maker, ugh, Stew Mac's fret placement calculator is so much easier for a beginner to understand, and for one who English is not their first language this calculator is quite simply not user friendly. Each their own I guess............JMO

I concur, I've been using Stew Mac's calculator for years, so Tal buy a metric measuring stick and use a pointed scribe for marking the fret position, buy a square and scribe the mark across the fingerboard, the scribe line will help guide your fret saw when it comes time to cut your slits for frets. 635mm is between a Fender scale and a GIbson. BenBob's scale length is a fine one to use and he gave you all the measurements you need.

link to wfret. I caution people to also check wfret with other fret calculators as in some instances wfret is NOT accurate as has been reported on other forums. My old computer and printer was way off using it. Also do NOT use paper glue to glue the template down, the paper will stretch and there goes any accuracy.

An alternative that works well for me: If you have access to a "real" guitar, you can use a long strip of paper and make a rubbing of the fret, nut and bridge positions. You can then transfer these positions to your CBG. If you do this carefully, it will result in a very playable instrument without the need for complicated measuring and eliminate the potential printing errors mentioned here.

To be clear, Bluesheart's simple method is a great way to learn, but you must use the same scale length (nut to bridge) as the guitar for this to work.
Re-reading the original post, I fear some of the responses may have further confused Tal.
Going back to the basics, although scale, tuning, string guage, layout are all inter-related, first thing you must do is choose a scale length. This decision is influenced in part by the desired tone or sound, practical size and how it will fit the chosen body/box. Best to go with the familiar for the first attempts so study what others have done and follow along. Once this decision has been made, then you can layout the fret or marker positions accordingly based on any of the above methods, as the positions are critically linked to the scale length.
Hope that helps a little.
A link to Crows video series on building a basic CBG in an hour may help, not exactly how I would do it but you cant get much more simple than that! Perhaps it will clarify things some for first timers. Theres also a great deal of information at various other places here, including this: http://www.cigarboxnation.com/group/scalelengthsetc?xg_source=activity

I said tone where I meant pitch.
And I guess I should have included the statement (opinion) that those who seek guitar pitches, growling Texas blues, swamp-stomp etc sounds are usually going to come from guitar-like scale lengths. 25.5" is common as it is used on the Fender Stratocaster etc.
Those who seek a more folksy/country/mountain "twangy" pitch are usually going to find it in a little shorter scale length. although this isnt always the case due to string guages and other factors. I have a lap dulcimer at 28", Banjo at 26" Uke at 17" and Mandolins at 14" or so.
Please keep us posted on your progress and feel free to ask any further questions.
And have fun!
Mark
