no problem i just thought you should know.
i've had some back and forth's with Glen who wrote most of it.
long as it's friendly and inquisitive it's healthy.

There's too much varying info that can be confusing at times...... a thicker plate most likely can end it and good feedback about them, too.

I for one like a thick sprue plate, more mass and holds heat better. A properly warmed sprue plate is every bit as important as proper mold temp.

The sprue plate should be loose enough to move of its own weight.

Guys let’s keep it civil.

Castmeister- you asked a question and people gave answers they felt would benefit you.
When he said a vector against the direction of motion he means are you applying force ONLY n the direction or pivot or is some upward or downward force involved as well.

Many of us here use an OveGlove or some form of heavy leather glove to protect our hand and use a therm to push the sprue plate- this lets us use only the force required for opening and not enough to bend the plate up or down.

I would suggest not telling other to not speak sea-heely vector as many of us here know exactly what he meant. You could have easily asked him to clarify his comment.

Think of this forum as being like a kindly old gentleman at a hardware store. Ask him for help politely and he will spend all day answering questions. Treat him poorly or rudely and you leave with your tail between your legs. This place is frequented by some people who have cast many tens or hundreds of thousands of bullets. Some shot the in competition at a high level and won with them. Those experiences made them very aware of what works for them.

As for the sprue plate - it is often the carpenter, not the hammer. Learn to make things work and you will be maxed at what can work even when it isn’t supposed to.

I actually learned alot from that site..... but there are some things they left out I read else where. A thick sprue plate and a lead insert in the bolt set screws. And a vector free falling.. after clearing sprues. Now I have to get the knack of manipulating the mould while pouring to prevent the plate from falling while pouring. Although It does have up and down play being free falling on it's own. I tried to adjust not to have that clearance but then it doesn't fall on it's own. Now what ? LOL

This whole process is a learning curve. The more you do it, the more the pieces come together. Practice and if it doesn't work, tweak it and try again. I assure you nobody anywhere ever got it right the first time and it doesn't matter what "it" is. Practice, practice, practice. Heed the advice the members here offer you, isn't any of them going to steer you wrong.

A scalar value has magnitude, a vector value has magnitude and direction. Examples:

5.0 grains of powder is a scalar value, it only has magnitude.

60 miles/hour going North is a vector quantity, it has both magnitude and direction.

H&G appears to have milled theirs from bar stock . My 8c looks like abound 3/8 . Between sprue holes and the canyon cut across down the length of it it holds about the same amount of lead as the 45 cal 196 SWCs .

Doesn't appear they are around any more

my sprue plates don't flap around in the wind.
you gotta move them if you want them to move.

that's me and my style, i also open the mold with a gloved hand.
i return the sprue right back to the pot before opening the mold.
i do lot's and lot's of stuff you shouldn't do,, but that's how i do it.

Drop in the sprues as you cast, ok.... I've done it. But I have a small pot, so it splashes.
Holding the mould vertically when placing the ladle to the sprue plate is how I pour..... pressurize. The flared spout to the holes on the plate fit well. So if the plate doesn't move, which it won't, it's no big deal, if flaps in the wind when it won't, if handled the right way, does it ?

nope the point is Rick does it his way, i do it mine.
sometimes i Ladle, sometimes i set up the 10 LB pot and pressure pour, mostly i bottom pour with a dual spout pot.
you just gotta hold your tongue right for a 3 or 5 cavity mold.
