For some time I have been eyeballing the semi-custom 1/64 collar-less ball head mold. Its the only one that casts a full load of the one size. What kept me at bay was this apparent need for a down filling smelter and those critters and I are not good company. I have several of the pro models and a couple in that line that make the 1/32 collar-less and I have no issues with missed or bad casts. The other day I had Jerry on the phone and we got to yacking about this dinky head and hook options and what not. The conversation finally came around to the lead delivery and I finally moved to get a mold to find out for myself.
Here's the skivvie on this puppy.
I use a Lee magnum melter and pure lead for the small jigs and I don't mess around with mid-range heat levels. If I plug this bad boy in I have it on HI. So I started there. Next I made darned sure the mold was HOT....the metal portion that is. And don't touch with bare fingers is the hot I refer to. Next I did some empty pours, no hooks, just to see if any of the cavities had any little glitches and yes that sometimes happens so I always do blind pours on a new mold regardless of what it pours. Of the ten cavities I found 8 that liked to fill to one side or the other leaving a half head. Out came the old nylon stocking for the rub test and sure enough there were very minute burrs in the gates of those cavities. A quick light swipe with a convex jewelers file and another trial filling. Perfecto.
Now the hooks. The catalog stated a size 12 or 10 570 style hook or the Mustad equivalent. I ordered 500 of the size 10 Eagle Claws to work with but I also had a few hundred Matzuo sickles in size 8. I prefer the sickle hooks but they stop at size 8 so I just laid a few in the mold and tried closing it and all was good so now to pour. I started with the sickle hooks since I had them out and after a couple hundred I figured I'd switch to the #10 and do the same number.
The finished heads are all nice and clean. They hand snap off the sprues so tools are really not needed...at least I haven't needed any. The heads are clean, no joints showing.
The bottom line here is that if you want a nice, clean 1/64 head without a collar, this mold makes making a mess of them a real snap. If you bottom pour you are set to hit it. If you ladle pour like I do, keep the lead pure, keep it hot and use a ladle that handles about three to 4 ounces of lead so you can control the pour as a fast straight in pour works very well. A real large ladle will stand in the way of this kind of control. Number 8 sickles work fine as long as you "feel" for them to seat as you lay them in the mold. The 10's were a breeze. I didn't have any 12's to try so I can't say how they work but I'll assume they're aok.
The price on these semi-custom molds is a bit but in the long run the time they save in finishing the jigs is well worth it and the quality of the finished head is as good as a spin cast head.
