I confess that I don't own much Lee products.
I have 3 of their 6 cav. molds that work OK (originally one was not aligned properly, but Lee exchanged it for a good one-I paid freight 1way). However: their mold handles have been my favorite. I have 9 that gave me good service, but the 10th. one has given me problems.
They did not align properly. I had an extra pair, so I disassembled both pairs (marking the problem pair) and switched them around & found that one side of the problem pair was the culprit. I emailed Lee & attached a photo of the misalignment problem. Their "engineer" pronounced them useable, but the nice lady in customer service sent me the metal part of a handle side (they call it "mold handle clamp") @ no charge, but I had to pay the freight + tax ($7.42).
Well, the story does not have a happy ending & the attached images tell why.
Images:
#1: original mold alignment # mold end
#2: original mold alignment from handle end
#3: original mold handle on right & replacement "mold handle clamp" on the left.
#4: original mold handle on left & replacement "mold handle clamp" on right.
The only explanation is that recent Lee mold handle clamps have a problem.
I emailed Lee today with these same images & I await their response. I bought the original handles from Midway for around $14.00 as a part of a larger purchase. Counting the $7.42 freight charge for the replacement handle, I'm currently out $21.00. If I am require to pay another $7.00 to return the replacement handle I may just call it quits & get some MP handles on the next GB. The MP handles are obviously better made, but I like the Lee size better (they but the mold 1/2" closer to my hand).
Added: I'm also thinking that I could clamp the ends into alignment in my vise & heat the pivot part with my oxy-acetylene torch.
