How thick do you measure your center marks.

I just got a new height gage for marking my blades. But i was wondering what is the most common thickness you guys scribe your blanks too. is 1/32 " to thin.Please let me know. thank's Jeff

Jeff, I don't have the answer for you but that is one fine looking height gauge. May I ask where you got it?
 
Main Entry: 1gauge
Variant(s): also gage \ˈgāj\
Function: noun
Etymology: Middle English gauge, from Anglo-French
Date: 15th century

1 a : a measurement (as of linear dimension) according to some standard or system: as (1) : the distance between the rails of a railroad (2) : the size of a shotgun barrel's inner diameter nominally expressed as the number of lead balls each just fitting that diameter required to make a pound <a 12-gauge shotgun> (3) : the thickness of a thin material (as sheet metal or plastic film) (4) : the diameter of a slender object (as wire or a hypodermic needle) (5) : the fineness of a knitted fabric expressed by the number of loops per unit width b : dimensions, size c : measure 1 <surveys are a gauge of public sentiment>
2 : an instrument for or a means of measuring or testing: as a : an instrument for measuring a dimension or for testing mechanical accuracy b : an instrument with a graduated scale or dial for measuring or indicating quantity
3 : relative position of a ship with reference to another ship and the wind
4 : a function introduced into a field equation to produce a convenient form of the equation but having no observable physical consequences

I see that some guys only put one center line and grind to it .but i want two lines and i will grind to them but want to know how thick i should leave the blade . I was told about this way .

"you need to take and lay your blade flat(on granite) then zero your gauge, then slide you gauge up and see how thick your blade is. I use that number and subtract .20 and then divide that number by 2 and that is the number i use I don't use a center line , i use the edge thickness i want it to end up being.Total of two lines"

I like this idea. how about you.
 
Jeff,

Edge thickness will be determined by what the job of the knife will be - straight razor: super thin. Hunter/utility, thicker, etc.

After marking the edge with layout dye or a black sharpie, I use a height guage/gage/gaige/gayge :) to scribe two lines down the center of the blank approximately 1/16" wide. I use 60 grit belts to grind the primary bevels, then 120 grit, then to HT. Finer belts further refine the edge after HT.

Thank's for the info Bill 2thumbs

As a general rule on straight knives, I take them down to .20. I use the method you described. Measure the thickness and subtract .20 then mark two lines. For folders I usually go a little thinner. Hope this helps.

BTW nice gage/gauge (take your pick, I tend to agree with Nathan on this one.):)

I make my marks 1/32" (.03") apart and grind to them, and then past them until the edge is somewhere between .03" and .02" thick prior to heat treat.

I have a similar gage and it works very well. You can get it from Grizzly as well.
