Started making shot on Sunday morning and shut down for about an hour around 2:00 and finally quit around 5:00. Final finish tally on my James Stewart "The Better Shotmaker" was 310 pounds of no. 9 (or there about) shot! The first shut down was unintentional, had a piece of lead stick in my discharge chute and caused the coolant to start to overflow. It did give me some time to get some other chores done though. Just thought I'd share with the group.

PS - all the lead was wheel weights

And what are you using for coolant? At what temp make's the best shot. Just wondering, I'm putting together a new setup. I don't want to go through all the multi-washing issues.

How about some pictures or video? Those of us in the shotmaking community are always looking for new ideas and inspiration...

I too would like to know what coolant you use and what temp causes you problems.

I have run crop oil and kept it under 110 degrees with a fan and transmission radiator. I am in process of changing to Sun detergent for what I hope is easier cleanup. I am also working on a continuous shot separator. Should be up and running in week or so. I have about 4 tons of shot to make.

There should be a section on trapshooters.com devoted to making shot. There is always something to learn, and it's hard to find good information.

OK, the coolant I use is 100% antifreeze with about 1/2 quart of detergent thrown in. I don't have a radiator yet but am looking to install a transmission cooler in the future. When I ran it Sunday for roughly 5 hours the temp rose to about 122 degrees. I keep a thermometer in the top. I'm still getting a dimple and have tried raising and lowering the coolant drop but no luck yet. I have noticed that my shot isn't perfectly round but I screen it trough a precision no. 8 which measures .0937. Here's the video I put on youtube if the above link doesn't work just copy and paste this one. http://www.youtube.com/watch?v=GeOgvvatkPM

I have a 4 gallon bucket that I drilled holes in the bottom and then covered with screen to drain the shot and then rinse it out. It seems to work pretty well unless you let it fill up too much and can't lift the damn thing!

The nice thing about my rig is that it's mobile and I can move it out of the way when not in use. I did make some heavy duty 24" x 24" screens for drying the shot. Each screen holds about 15 lbs of shot and I've set it up with a fan blowing across it and it doesn't take long for it to dry.

Rick, thanks, I put a lot of thought into it and have to credit jim101 for all the ideas I got from picking his brain. It's currently in about the 8th or 9th generation from when I first started cutting steel. I can load almost 300lbs. of ingots on the top and that will keep the pot fed for a while. I still have a few bugs to work out and when the pot is running the whole set up is a little high maintenance where it comes to the coolant. In the middle bucket I have a submersible pump that I need to turn on from time to time and in the shot catch bucket I need to ladle the coolant out too as well as move the shot to the drain bucket.

I use a 25-30 gallon tank and a high temp pump. I see your using the Harbor freight pump...super cheap good pump but I was unsure of its heat potential. In our set up since it has that kind of volume we never hooked up a cooler to it. We run it 5-6 hours straight and the temps level off at 125-130. Very similar to what you are seeing. We are running the black max with doubles in 7 holes. Our output is 125-140# and hour and that is cleaned dried sorted graphited polished and bottled. Biggest slow down is getting the dang ingots ready. Plus ww these days are running alot higher on waste. We are seeing lots of the zinc weights. We are also considering changing the trade out margins because of that.

Any more experiences with using water as coolant? Been too hot to play with it in Missouri, but am going to try water and run a hose thru to cool it. Beauty of this game is you get do overs. I also came up with more linotype than I need for myself. If someone needs some, figure about 75 cents delivered. I know it brings $1 on EBay, but they don't need everything.

kd185, yes, all the time!

himark, That's a pretty impressive rig, thanks for the photos. I was wondering about the screen in the mixer too.

I haven’t made shot in 10 years but, we used water soluble oil that you get from the Shell Oil Company. It was a water/oil mixure.

Shootintom: Gotta tell you your machine is pretty cool.. Best effort I've seen yet! One thing though,,, What is the heat source? is it a burner or is it electric?

Also, I would suggest if you could blow a stream of air or maybe several "curtains of air" on the separator screen it would blow most all of the water off the shot as passes over the screen. Otherwise it will stick on the screen and on the shot because of surface tension, and capilary action.

A vacuum cleaner set up to blow instead of suck might be the answer with a piece of PVC with slots cut into it to generate curtains of air..

2 or 3 PVC crosses in series with shot rolling one direction thru and a screen across the the gap with air blowing down on the screen, might be just what you're looking for. Shot goes one way, and the air and water goes the other.
