Guide Pins On 2 Part Aluminum Molds

Recommended Posts

I am trying to find some guide pins like the ones they use on aluminum molds. I have only seen these in one mold and it was not from any of the mold makers that are referred to here. I didn't take any measurements of it

I have been using a 1/4" dia. x 1/2" long dowel pin and it is a little too big.

McMasterCarr has a 3/16"x3/8" dowel that I may go with. I would like to have a bullet nose pin but the ones I have found are 2-3 bucks each.

Does anyone know of something better than what I have found at McMaster Carr?

thanks,

thanks for the replies, I tried MSC, Enco, Google, and didn't find anything better than MCC (McMaster Carr). Actually MSC had some that were cheaper, but the reamer was higher, so I guess I will go with MCC.

Here is a pic with the 3/16 pin.this is a 1/16oz lead head #4 hook, 1"x1.25" mold. I may go with the 1/8 so it will be easier to put the mold together. Probably use LocTite Stud and Bearing to lock in the bottom pins. thanks for your thoughts on this.

I use 3/4 long 1/4 diameter pins press fit. Well hammer fit. I use a D drill bit on one side and an F on the other. Then I half drill the D side with the F bit. Works great.

That's interesting. Do you have any sloop when fit together? I have been milling with a 3/16" bit to .250' and then use a reamer. I like the way the smaller pins fit the 2 halves better. With the 1/8" dia. and the 3/16" pin sticking out. Now, I have not made anything with the 1/8, I was looking at a mold that belonged to someone else. I got my pins and reamers today. I am going to try the smaller ones to see.

I like the sound of your method, but I think I want it smaller.
