Lightening Grooves
 

xxxxx

has any one figured out how much weight that actually saves?

maybe weighing two same sized frames sans wood - one grooved one not

at least it looks really cool

I bet it shaves off an ounce maybe a little more.

that is what i was thinking - you can save that by carefully selecting wood.

So was it a complete approach to get the weight down. lightening cuts on the frame and chose light wood - holes are often drilled in the buttstock - but my impression is they are as much for balance as weight

I have a 16ga lifter and a Top lever hammerguns, the lifter has the cuts the other doesn't both have 28 inch bbla and I can't tell much difference in weight. On the other hand I have a GHE 16 O frame with cuts and BTF with 28 inch damascuss bbls thats as heavy as a #1 frame gun.

i think it's more marketing than anything else.

Calculate the volume and multiply by .284. Low alloy steel weighs .284 lbs/cu.in.

so - good excuse to buy one with lightening cuts so that I can measure it :rotf:

One gun I am building (a VH to CH upgrade) on a 2 frame, I milled out the underside of the forend. And that saved 1/2oz. I do plan on milling out he water table on my 20g hammer gun I am building. So I will post the results of what the weights are before and after once I do it. I would wager an ounce as well.

At one time, I calculated the weight savings on an 0 frame lifter to be about 1.5 ounces. The lifter has one continuous cut, unlike the top lever that has 2 cuts per side, interrupted by the check-hook rod.

The lightening cuts on the 0-Frame lifter consist of one cut per side with a length of 1.92" each and a width of .38" wide each and a depth of .112" for the cut on the left water table and .102" for the cut on the right water table.

As a comparison, the lightening cuts on an 0-Frame T/A consisting of two cuts per flat are 1.37" in length each for the cuts to the rear of the check hook rod and .89" for the forward cuts. The width of these cuts are .37" wide and .102" deep.

Okay fellas, get out your slide-rules and figure the ounces saved on the lifter and the ounces saved on the T/A....... Ready - Get set - GO!!
