bradders Posted May 12, 2015 Report Share Posted May 12, 2015 Well, someone dropped round this morning and dropped their barrel off for a spot of Dimpling 90 or so minutes later...... That rotary head was a great purchase Link to comment Share on other sites More sharing options...

brown dog Posted May 12, 2015 Report Share Posted May 12, 2015 Looks better than I'd have thought. Don't suppose you have before and after weights? Link to comment Share on other sites More sharing options...
bradders Posted May 12, 2015 Author Report Share Posted May 12, 2015 Looks better than I'd have thought. Don't suppose you have before and after weights? I have a more or less identical barrel without, so I will weigh both I may do this next http://home.comcast.net/~sfischer397/pictures/aics/aics-f.jpg Link to comment Share on other sites More sharing options...

bradders Posted May 12, 2015 Author Report Share Posted May 12, 2015 Just weighed it, 1134gms, a non dimpled barrel of the same profile weight 1168gms, so weight saving is negligible, but the chicks dig it Link to comment Share on other sites More sharing options...
c18rch Posted May 12, 2015 Report Share Posted May 12, 2015 That looks kin orible but each to their own. Nice work though. ? Link to comment Share on other sites More sharing options...

terryh Posted May 12, 2015 Report Share Posted May 12, 2015 That seems crazy-low...umm, did both barrels have barrel extensions fitted?! 34g of steel = approx 4.25 cm3 (excuse non metric unit!) using a nom RD for steel of 8g/cm3, so does seem low. But what the heck, fluting etc. is a visible addition (and chicks dig it!), dimples are different, I personally like the 'skip' fluting. Each to their own.

Vermincinerator Posted May 12, 2015 Report Share Posted May 12, 2015 Nice bradders, i dont know if you have thought of it yet but if you have a take off shaft on your dividing head you can rig up a gear train to the table lead screw of your milling machine and cut helical flutes.

gbal Posted May 13, 2015 Report Share Posted May 13, 2015 Mark,good to see some innovation over here. There is really no end to this art: helical alternate dimple interrupted is just starting -it would give morse code,though actual messages would remove some symmetry (and be unreadable by most). "Long Rifles" used to do it,as did the interestingly named "Twisted Barrels", in US. gbal Link to comment Share on other sites More sharing options...
