So the sequence is:
1) Can hard wax be melted & poured into RB moulds to produce consistent quality hard wax RBs?
Well, my results started out GREAT and then got funky. I lubed the Lee mold with Pam cooking spray with olive oil which is my favorite release agent for epoxy work when working on uhhhh, modern rifles and old boats. I used a cat food tin on an eletric stove on 2.5 to 3. It took a good 10-minutes to melt 20 of them and once melted it's consistency felt a little thinner than a liquid epoxy mix, maybe more like maple syrup. Next time I will put a flat pan under the cat food tin, as wax dripped down the edge and started hitting the stove. Maybe the double-boiler method and warming in hot water would be better?
Back to my Waxenstein experiments, courtesy of Roundball ... The 1st one molded looked and dropped great! So did the 2nd one, woo hoo - we're on a roll! Then with the 3rd one, I had to start over, as the wax cooled off once I was halfway pouring #3. Then another #3 attempt was successful. #4 was like #3, but a big block of wax hardened or 'something' about 2/3rds of the way through the pour and I couldn't complete the pour.
Attempt #5 failed as did ALL other attempts afterwards. I cleaned the mold, re-lubed, tried no lube, put the wax temp up, put the temp down ... as much as you can on an electric stove - but with no succuess
.
Note that all during these failed attempts, the wax, though melted, felt 'thicker' and I just couldn't get its original viscosity back. I wonder if I overheated it when I wernt up to "3" on the stove ... ??
GOOD NEWS:
For a mere sample of 3 pieces, 2 weighed 22.1 grains and the other 22.3 grains. The failed #4, which was part hollow, was 17.0 grains. A 'blank' 45 cal wax bullet as Roundball sent me weighed 16.2 grains. This would be COOL if we can get it to work, i.e., molding and shooting, in a smoothbore, as he paid $20 for 1000 (45cal) I think it was, so one could possibly make about 670
wax roundballs in 600 size for that price.
The picture with the mold doesn't show it, but a round wax 'plug' about the size of a BB blocked the fill port and created havoc on the 5th attempt. Whatever the solution is, I think the temperature will be critical ... and we need to find out why the melted wax got 'thicker' as I proceeded.
So .. whaddya think?
