Experiments with capitals for the S&P beam
« on: October 19, 2012, 09:21:38 AM »
OK, despite sticking my face out and claiming the 30-06 case would be a good starting point, a quick look this morning didn't turn up any at all (though I know I have some) .... so, a minor change of plan - found heaps and heaps of 308W (7.62 NATO) so, for the first try we will use those.

The older I get, the better I was.

Oops - a bit of resizing in order. Having problems with my photo hosting service - attachments for the time being I'm afraid.

Step 1; turn away the extractor groove in the bottom of the case and drill what is left of the flash hole out to 6mm.

Step 2; trim the case body down to 25mm length

Step 3; divide a portion of the case (20mm from the open end) into 8 more or less equal segmants

Step 4; cut these segment lines with a Dremel cut-off wheel

Step 5; gently flare out the segments with a pair of long nose pliers.

Step 6. The insert was turned (reasonable fit inside case) from a piece of 20mm square brass.

Step 7; ... and shoved into the case, seated home with an M6 bolt and nut.

Right way up! Ready for trimming and shaping of the 'petals' - gonna all be hand filing I suspect.

Watch this space.

A long way short of perfect, but on the right track, I think.

 ;D Well, getting somewhere near it. Now I need to try one with some decent set-ups for the cutting and shaping - that was just knocked out more or less freehand.

Looks really good. Interesting process and good use of a spent cartridge.

I don't see the pics in post 6 and 7.
