Project Information
I was not going to post this, but then I thought it might be of interest to someone wanting to make an easy mold. I have not been making many wood things lately and this was wood so it qualifies. It is a walnut mold with 2 aluminum core pins for counterweights for my new solar panel system. I made it to mold lead counterweights for the top horizontal bar so that the frame is balanced for turning with ease at different angles. Doug Scott was over last night and we thought it might just burn up when I poured the molten lead into it but it just blackened and made perfect weights with screw holes down the center. These will fit into the 13/16" high Unistrut channel that I used for the frame.
I did not take any before use pictures so I pulled it apart afterwards to show how it was built. I cut out the inside on the table saw tilted at 2 degrees and then the ends were cut at 5 degrees and the pins turned at 2 degrees. This gave enough draft angle for the pieces to fall out of the mold when cooled. I broke two of them when I took them out too soon,but they easily melted down for the next shot.
Doug, thanks for the bucket of wheel weights you brought over today for future molding!!!!!!!
The 4th shot is a piece of Unistrut and they fit great. The last shot is the assembly and the weights will go across that top horizontal frame member. They weighed in at 2# 6 oz each.
Cheers, Jim
