My point was that it is not likely that the makers paid high dollar for the fine mold making that you refer to (they are not producing these for rocket sceintists). I don't think the inventer went to the casting maker and told him "After years of shaving and adding thousandths of an inch here and there, I have finally made the perfect jig. Now I need you to reproduce it exactly to within 1/10,000 of an inch". On the contrary, I would bet that they were generally happy with the way there jig shape swam, and wanted to get it to market. On closer examination of the same jigs, you can see differences between the 2 Lite 6Xs (jigs #3 and #5). The holes on either end of the one on the left are larger than the one on the right. There is also a difference in the Ss on either end of "SALAS".

The die making process is by it's nature is accurate, as the whole point, the whole reason the process exists, is to make a mold that produces an accurate duplication of the product in mass. I mean they cast carb bodies and all kinds of things this way. This type of project would be a piece of cake to a die-maker, a real no brainer. There is no way they would screw it up if they knew what they were doing. Basically anyone with enough skill to make the die is going to make an accurate die with a project like this one.

Holes are notorious for flash where a small amount of metal seeps out and fills the space, I imagine they have to drill those out and clean them out during the chasing phase. Having done a shitload of chasing I imagine that those holes vary in size do to available tooling..LOL

In other words they probably use whatever drill bit they have sitting around that's still sharp at any given moment, on any given day.

With any kind of casting the chasing (cleanup) always creates idiosyncrasies, but that's not a reflection of the mold so much as the hand of whoever is doing the cleanup. It's a constant battle with chasers, they love to use their tools, and sometimes it's hard to convince them that less is more, as the less you chase (sand, drill or grind off) the more of the original remains.

I think those discrepancies your seeing in the S can be attributed to thickness in finish. To me it's rather obvious the finish is a built up a little thicker on the left side of the number five jig where it's more even on three. Essentially human error. That buildup was caused by someone spraying it multiple times trying to get the color break right on that side.

You can see the another thickness of finish issue in the new mold number two jig where the J in JR almost disappears because it tends to fill in. That's a design flaw, when they figured out the letter placement they did not take into account the sag in the thicker finishes during curing.

That exact issues shows up in the majority of jigs cast from that mold. Since they cure them front up the J being the highest letter takes a hit.

according to Brandon Hayward in his book getting bit.
"surface irons are sand cast and ground down by hand. where as yo yo irons are die cast and do not need grinding.
essentially thats the mayor difference between yo yo and surface irons"

also yo yo's are zink and surface is aluminum alloys

Thanks a lot guys for the great info on irons. I believe my old 6x Jr was inherited from my dad so it was probably one of the old light versions. Good to know I'm not nuts. Bad to know it won't be easy replacing it.

I believe I recently glanced through a copy of the book roadx quoted from. The author said he could tell which irons would swim well just by looking at them. If I remember correctly, he said the sharper the edges, the better they swim. The variation came from the hand finishing. I'll have to keep that in mind the next time I buy an iron.

But back to Iceman's topic. I caught my first BSB Sunday. SOB towed me way off the squid grounds and wrecked my rod holding arm. I hope that's the last one I ever pull on. Here's a tip I learned the hard way. If the air bladder ruptures and is venting on its own, (my BSB was 'farting'), work quick to unhook it or cut the leader. I wasted time videoing the fish. By the time I realized what was happening, it sank and there was nothing I could do to stop it. I finally had to cut my line to keep from losing even more spectra. I'll be glad when they move out of the area.

Tight lines ... but no BSB!

So good swimming jigs off the shelf should 1) have off centered top hole 2)uneven (non-conforming) edges 3)non-binding hook that is attached to the ring???. Thats the way I make my iron purchases
