I'll add that you can make your mold out of plywood(3/4" thick) with simple 2X3,2X4 framing stock,depending on how complex the shape.The entire interior of you mold must be generously coated with the water glass and allowed to be perfectly dry before pouring.Simple slab sided ballast keels are easy enough. When you are ready to pour, bring the lead to a liquid state but do not over heat it needlessly.That is, do not wait until you see a purplish sheen on the molten surface.<br id="yui_3_16_0_ym19_1_1473397890941_5967"> Yes, your mold will smoke and there will be charring but it will be minimal and have litle to no effect on the casting itself.Allow for some small shrinkage too. Work smart when dealing with the molten lead.Ie: plenty of ventilation, wear heavy full coverage clothing and stay focused on the task.<br id="yui_3_16_0_ym19_1_1473397890941_5968"> </div></span><div id="yui_3_16_0_ym19_1_1473397890941_5969" dir="ltr"><br></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1473397890941_5926"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1473397890941_5925" style="display: block;"> <div id="yui_3_16_0_ym19_1_1473397890941_5924" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_ym19_1_1473397890941_5923" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_ym19_1_1473397890941_5922" dir="ltr"> <font id="yui_3_16_0_ym19_1_1473397890941_5921" face="Arial" size="2"> <hr size="1" id="yui_3_16_0_ym19_1_1473397890941_5951"> <b><span style="font-weight: bold;">From:</span></b> Brian Cox via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, September 9, 2016 6:36 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] lead Smelter<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1473397890941_5976"><br><div id="yiv3325698415"><div id="yui_3_16_0_ym19_1_1473397890941_5979"><div id="yui_3_16_0_ym19_1_1473397890941_5978" style="font-family: Arial, sans-serif; font-size: 10pt;"><div>Wood ?

It still hot but should cool down soon. I cut a big hole in the bottom of my sub ( concrete part) I can stick my head in there and look around ! I'll be fitting lead in there. I also fired up that smelter and melted a bunch of lead, works really good ! I didn't do anything with the lead I just wanted to see how long it would take to melt. Next project is to make metal forms to pour the lead into, and to make my drop weight assembly. </div><div> </div><div>Brian </div></div>
