      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

centirfugal mold

Has anyone made there own. Just looking for an end of winter project and to make some custom jigs for personal use.

Why? Just be sure your mold is preheated and you use alloy free lead (no tire weights). You should not need the centrifugal force to pour perfect castings.

because tire weights are alloyed lead, it freezes at a higher temprature. I want to use a centrifugal mold so I can make a wax model of a jig and them replace it with lead. I knew a guy who made one and used it to make jewlery. The amount of detail you get get is awesome. Also it would be a lot better than a machined mold and cheaper. I could play around with with the different designs I come up with until I find one I like, then I could get a mold made for that one.

So you want to try investment casting!

Check out jewlery supply resources and you should be able to find a setup. I think they work on a spring principle where you pour the metal and let it spin!

Thats a pretty big operation to set up. I used to have one. My suggetion would be to wax your patterns and go to a dental lab and ask them to cast them for you. They will not use lead but a non precious alloy. If you want to do it yourself you will need the centrifuge, investement rings and bases. Investment,tongs and a torch. These can be found in jewelry and dental lab cataloges. You will see they are pricey. Another way to go is with silicone molds. You can pour those directly with lead. This is much faster and you can get as much detail as you want depending on your mold making abilities.

Why not try this: Since the initial pressure in the mold is a function of the specific gravity of the material times the sprue height, why not burn out the investment, fix a tall sprue pipe to the plaster and quickly pour the metal. You should get a hammer effect as the sprue fills up and pushes the molten metal into the mold cavity.

so just use the weight of the lead to fill the cavity like on a normal mold, but make the sprue longer? I wonder if you would have to keep the sprue pipe hot the enitre time with a torch to keep the lead from freezing and clogging it. Sounds like a good idea though.

ddbyday- how do you make a silicone mold??? what kind of silicone do you use?

Pure lead pours with as much detail as a centrifical lost wax investment casting. The investing and casting method is way too precise for a fishing lure cast with lead. As said before avoid the wheel weight lead. It is too hard and does not cast well. Investment(the material you encase your waxed jig) in is designed to compensate for the dimentional shrinkage or expansion of the object you are casting when it goes from a molten state to a solid. This ideally would produce an exact repica of your design. We are talking microns. I assure you this is not the way to go. U tube has some very good tutorials on mold making. The silicone is basically vulcanized rubber. Hilts molds is now taken over by another operation but you can get the silicone blanks which you vulcanize yourself. There is a really nice video on u Tube about centrifically casting vulcanized rubber molds for high production castings.

Awesome info! Yeah like I'm sure you can tell, my eperience with these types of molds is limited. I have seen it done though, and remember it as being pretty simple, but I guess some things are easier said than done. Thanks for the information though, i appreciate it!

    • The 30 is a log to have to carry constantly but sure is nice to have to keep the bait lively!  I went last night and purchased another pump in order to plug into the wall...$13 and all I have to do is move the tube from one pump and connect to the other.  I am seeing if I can easily keep minnows alive from one weekend to the next.
    • Wow, someone else who actually watched the video and figured out what Williams did. Thanks @nofishfisherman.   It should never have gotten to that. The Vikings have got to keep playing to win for 4 quarters.   Playing to protect a lead can get you into trouble much faster than it's likely to help.
    • The mistake was getting there too early, clearly if he had continued with his tackle he would have been there way too early and would have an easy PI call against him.  Had he gotten a PI call then no matter what happened after that the vikings would have had a shot at kicking a field goal because a game can't end on a defensive penalty.  By avoiding the penalty he at least forced Diggs to make the catch and avoid any other tacklers.  In most cases the WR is going to catch that ball and get out of bounds right away no matter what. It was just the perfect mix of circumstances for Diggs to take it for a TD.  Had Diggs simply been facing a different direction after the catch he wouldn't have seen he had a clear path to the end zone and would have likely stepped out of bounds to stop the clock. Had Williams not taken out the other DB he may have been in position to make a tackle or at least be close enough to perhaps make Diggs think the best option is to run out of bounds instead of risk getting tackled in bounds.    What I found more puzzling is the overall defense from the Saints.  I've seen it broken down a few times and they had several players guarding against short passes to the middle of the field.  That vikings had no time outs and needed at least 20 yards, the Saints should have been inviting them to through short into the middle of the field not actively trying to take it away.  It appeared the entire play was a complete mental breakdown by the Saints.  It will go down as a great play by the Vikings, and it was, but it was made possible by some pretty big mistakes by the Saints defensive play calling and a single mental breakdown by Williams. 
    • Has anybody found this particular color of rattl'n flyer recently, i am down to my last 2 and i havent been able to find them in pushing 2 years.    
    • Good deal! Did you leave the ice coned up to help keep a seal?
    • Update: took the shack out this weekend had reflectix and fans blowing in the holes and they stayed open in the -20 windchills 
    •   I also saw a picture with Blair Walsh's face on Marcus Williams as he is missing the tackle.........wide left. 
    • Copied from FB:   A friend of mine has two tickets for the 2018 Super Bowl, both box seats. He paid $2,500 each but he didn't realize last year when he bought them, it was going to be on the same day as his wedding. If you are interested, he is looking for someone to take his place...It's at St Christopher’s Church, in Edina, Minnesota, at 3pm. Her name is Samantha, she's 5'4", about 145 lbs, good cook too.....She'll be the one in the white dress.
      (Feel free to copy and paste, to keep the laughter going!)
    • The saints player was probably running to where the ball should have been thrown. That throw was 2 yards onto the field, should have been closer to the sideline. It would have been a pretty easy tackle to keep him in bounds and the game is over.. Nothing wrong with a little luck on our side. I thought the refs were terrible all game. Lots of questionable and no calls. That last no call when Theilen got mugged was ridiculous...
