| Speaking with what must be very limited experience, I can advise you to make sure that when lubing the "V" guides on the mould blocks, make sure that you use the tiniest amount of lube. As the aluminum molds tend to like HEAT, the hydrocarbons from the lube just get everywhere. Same goes for the sprue plate. I actually find that Midway drop out spray on the guides prevents damage just as much as a bullet lube. Of course others may post differing opinions, with better ideas. I'd like to hear if anyone has something better to add. Here's another stupid thing I've done. When casting HOT for those Lee molds, the frosting on the projectiles is fairly severe. This seems to make no difference to accuracy, but I was feeling self concious about it. I tried tumbling the projectiles in corn media, in a vibratory case cleaner. After about an hour the projectiles had a uniform flat, dark gray look to them. Sort of like moly coating. They weighed and measured the same as prior to the shake up, with no roundind of lube grooves or bases. No difference in accuracy, but they looked better, and looks have got to count for something, right? |

| Lee reccomends smoking the cavities with a match. Seems to work as well as spray-on products. A butane lighter can also be used. "Color" completely the top of the mould and the bottom of the sprue plate with a No. 2 pencil to prevent lead streaks and galling. Welcome to casting, curmudgeon |

| Cheeky, Interesting solution to improving the appearance of your frosted bullets. I've agreed wth Lyman's and you on this one for 30-odd years and don't worry about frosting. Frosting, to me, means that everything is well warmed up and I'm not making "raisins". Regards, curmudgeon |

| Dear Lar 45, I believe the correct term to use for your spueplate wacking stick is the "Sprueplate-wacking stick". You'll agree that the hyphen makes all the difference, as the stick is used for sprueplate wacking. So it's correct to hyphenate the words. A better idea than actually belting your molds up would be to rap the bolt holding the mold handles together. Like wise hitting the steel of the mold handle should also be successful, and I might add, far less expensive than attacking the molds. I've found that wrapping a few layers of duct tape ( much better evidence that highly advanced aliens once visited earth and left some of their technology than those Raelians can dream up), around a bit of 12 inch X 2 inch alder, or oak or whatever hard wood you can find, sort of gives you the iron fist in a velvet glove effect. When the duct tape falls to bits, every 1000 projectiles or so, just re-wrap. Good as new! |

| Lar45, It IS the sprueplate-whacking stick NOT the moldblock-whacking stick! It is however acceptable to tap the mold handle hingepin with same stick however to encourage boolit fall. Smoking molds, all I use is a kitchen match. The boolit hang up you're experiencing is prob'ly from burrs along the edge of the cavity. I generally try to hone them out using a boolit from the same cavity, drill into the center, using a screw in the hole, chuck it in a battery operated drill (for slow speed), put a little bore paste or other FINE abrasive on the boolit and spin'er. Just a little 'cause you're dealing with aluminum here and we're not trying to enlarge the hold, just smooth'er up. Clean it all up and start that break in all over again. Ain't it fun?

| Lar45, those boolits I sent you were Lyman or Ideal 311291 before I used the Beagle Mold Enhancement on the mold. As for lapping your mold to make it larger, I'd darn sure opt for the Beagle method first, It's reversible. Regards, Woody |

| Speaking of sprueplate whackers..when I started casting back in 1960, I need such a gizmo. I went to the tool department of the local Sears store and bought a 16" heavy duty hammer handle. I hold it by the small end (hammer head end) and whack with the thick end. After almost 43 years, it is still whacking away. I used it this afternoon. I am now 60, so I guess the same one will see me to the end of my road. Talk about getting my money's worth! Take care and keep em in the X-Ring. |

| lar45, Check out the problem mould thread down the page a ways. Beagle method described there. Regards, Woody |

| The poor man's source of sprue cutter whacking sticks: oak pallets. Many pallets, or at least the 2x4 parts, are made of oak. One good oak pallet has furnished a lifetime supply of whacking sticks, lead pot handles, and dipper handles. Some of the 1x4s made replacement steps for a friend's van ladder. Most warehouses will call you blessed if you take a broken pallet off their hands. Regards, curmudgeon |
