Free 3D Printed Metal Casting Tools: Tapered Sprue Former and Surge Trap

[@johnmccanntruth]

Lawyers love Paul. And get to casting, we know you have nothing better to do than to entertain us!!!

[@PaulsGarage]

Haha my lawyers, if real, would regularly slap me for everything I do here

Hey Paul. Your videos have inspired me to pursue the craft of casting metal objects in sand. I've only been following for a few months, but I've watched them all. Well next weekend I'll be attempting cast aluminum bronze knives, having zero prior attempts (I still need to temper my graphite crucible). Even so, the information you have provided I feel confident that I'll do a half decent job of it. Based on this video I have crafted a spin trap and tapered sprue out of a dowl (I don't yet own a 3d printer). Thanks for the witty self deprecating humor.

[@firearmsstudent]

In the metric world (or at least Japan) NAFCO or homes (their version of Lowes and Home Depot) sell it as 6.35 mm pipe, so same exact thing just different numbers.

[@JulianMakes]

Ooh I like your description on how the spin/surge thingy works, I’ll print one of those and try it out, cheers :)

[@FloweringElbow]

Again - enjoy this my friend. Keep the casting fun coming ;) Am about to attempt some more CNC parts that are a fair bit bigger than I have before... Peace, Bongo.

[@rogerforrester9845]

In Australia we refer to copper pipe sizes by OD. So: Print at 157% and use 1/2" pipe

[@nutsandbolts3729]

I would start the lathe build and cast the tail stock later, in case there are unforeseen issues that you may need to compensate for...

[@InsideTheMindOfMatt]

Great to see some more evolution in technique in the community.Always fun to watch you kick your own a$$ looking forward to your next video regardless the content Ginger Power!!

[@TrojanHorse1959]

Great video Paul, I love your presentation and humor, thank you!

[@LooseChange7325]

I have some parts that I would like to cast this summer,watching all of your videos is inspiring! I will definitely want to try to make more green sand and do a spin trap!

[@Thewulf56]

Thanks Paul. Will have to give them a try when I'm back at home to print them.

[@runliftthrow217]

totally agree on the surge traps. I'm seeing an immediate difference in porosity level in my castings. I'd share footage, but that would mean I would need to video it, upload it, share it... improve my channel... avoid the urge to us bright yellow Indiana Jones fonts, possibly change my account name to something relevant... too much work. I'll just sit here and agree with you.

[@The_Phantom_Writer]

Thank you! Brand new to metal casting, so you definitely helped jump start my hobby ^_^

[@drewfausett5388]

y'know... i've often thought, "Man, Paul's artwork is JUST LIKE if Picasso had brain damage... from a fight with a primate"

[@samuelgeer4332]

Cast more stuff@!! Very inspiring

[@TheLgonzal1]

I love your design, I'll definitely give it a go when I try this down the line. It occurred to me while watching your video... to save on having to clean it up after you take the 3d printed parts out..instead of burying the part a little ...couldn't you take a short, thin heated wire and shove it into the bottom flat part of you 3d printed part? that will let you stick the part into the sand like one of those ugly plastic flamingo things... no idea if that would work... I have never tried casting anything before, but your videos are definitely motivating me to try. looking forward to seeing the rest of your Gingery build

[@WarGrade]

Pall, reduce your overall molding height, Keeping the whole thing as low as possible will give you even better casting results. Martin taught me this a long time ago, if you get your sprue & runner system sorted, you will find you do not need a tall sprue. Keep pushing the word out there dude

[@SvenIronhand]

You can get 6mm copper pipe in metric countries for HVAC and fridges.

[@boltonky]

Wicked video have to re-watch this before i do casting again....I am still amazed people can upload videos, i tried once and took to much time out of my work day and sadly i know if there are other people like me they would probably want to see my vintage machines + tools and the other crazy i get up too ( ohh wait i am broke so i should stop buying stuff haha)

[@PaulsGarage]

yeah making videos is crazy time consuming. Still fun though

[@mhypersonic]

I just make a hollow funnel using sand/sodium silicate mixture 10 to 15%, you should look into using sodium silicate. Its great!

[@swdweeb]

Big honkin. I knew I was there was a better way to describe it :-D

[@StripeyType]

All of this is indeed why one pours a pint the way that one does if one both enjoys a pint and knows how to properly pour said pint.

[@MarkATrombley]

I think you should do what you want. You are anyway so why not? Or you can cast a full scale model of the Hindenburg. That might be fun.

[@pekkasaarinen2902]

I noticed you as a participant to Project Egress. Some sheet metal work perhaps?

[@PaulsGarage]

Yes indeed! Not sheet metal this time, I'm sand casting a part in aluminum

[@sdspivey]

The spin trap will not move the sand to the outside, as the sand is less dense than the metal. Also, you should have made the spin trap junction the same size as the INSIDE of the pipe, then it wouldn't need to be "cleaned up" afterwards. It wouldn't shift either.

[@wjp6480]

Cast more things! Build more things! Do all the things!

[@mikemcdonough3221]

Thanks for the Prints, your Channel is Great.

[@edgeeffect]

1/4 inch is about 6mm...... finally a useful comment from me.

[@firebird8600]

Which filament is that? I've used ESun "luminous Blue" and it didn't glow anywhere near that well. The glow is so wonderful!! (The rest of the video was pretty good, too... hahaha)

[@madmartigan4141]

I swear that google is watching us. I literally just took the same tools I made, based off of swdweeb's designs, off my printer, then sat to have a coffee and watch some KZbin and this video was at the top of my feed.

[@mindofmadness5593]

I'm missing something. Metal goes in, flows along the pipe to the spin trap then goes backwards to fil the item cavity? Sems it would fill the item cavity before proceeding to the spin trap.

[@Astrom27]

Cool vids , Im going to be starting my Gingery lathe castings here soon. would this still work for larger castings or just increase the dia like you said.

[@PaulsGarage]

I've done some castings where the part was a pretty large volume of metal and 1/4" tube still filled the part fine. You just need to keep the sprue full to the top and keep the metal moving. Increasing the diameter is sometimes a good idea as well

[@markfryer9880]

The 1/4 inch sprue system will accommodate anything that the home caster can pour from the readily available graphite crucibles. The main problem is shrinkage prevention by the use of risers and where to locate them to feed the cooling casting.

[@farmerdiy9024]

CAST MORE THINGS!!

[@PaulsGarage]

One vote for more casting 👍

[@wildpowell3675]

paul couldn't you make ends on your taper and spin trap to accept the copper like a 1/2 inlet topside just for better stability till you get sand packed

[@markfryer9880]

He could if he thought about it hard enough, but this is Paul we are talking about.

[@MtnDan-d4g]

Seems like a quarter inch is too small. I assume it works ok?

[@victor440_]

Great job 👍 thanks

[@brandt-heiss]

I like your Videos. Please keep doing this

[@PaulsGarage]

Will do! Thanks!

[@dfross87]

I think a casting video would be appropriate for next week. Maybe not the tailstock, because you haven't yet proven these new parts work correctly. So the question becomes, what should you use as a test casting? How about casting an aluminium sprue former and an aluminium spin trap? They'd be more durable than the 3D printed parts, although they wouldn't glow in the dark.

[@emaglott]

Now I understand the spin part of spin trap. start building lathe, cast more l8r

[@dizzolve]

did it work good?

[@centaurus777]

1"=25.4mm 1/4" = approx 6.35mm :-)

[@jasonkrohn5416]

You should think about casting a bronze skillet. Ok I’m not going-to suggest this anymore I promise. Well maybe. 😬

[@dmhawv]

I love your craziness. But I am so sad. I live amongst the feeble few metal melters who do not own a 3D printer, don’t know anyone with one and so I am sad and full of sprue and gate envy.

[@markfryer9880]

You can use a artist's large brush as a tapered sprue and small poly hose pipe for the runners. The various shapes are out there you just need to think laterally to find them.

[@flytrapjohn]

Sprew envy.😂

[@dmhawv]

Improvising I’m good at, appreciate the suggestions.

[@askquestionstrythings]

What angle is that tapered sprue and how long is it? Cast more things

[@producersteve1330]

8 inches in length, tapered to 1/4 inch match his 1/4 OF copper pipe gates.

[@askquestionstrythings]

@@producersteve1330 What is the OD at the top? based on some rough bernoulli's principle calculations from the length you provided I assume it would need to be about 0.433 in (7/16in) and have a 0.7 degree taper

[@producersteve1330]

I'm sure if you follow his links Paul provided, the files likely contain all the measurements you are asking for. As far as my tapered sprue, I used an 7/8in wooden dowel cut to length of 8 inches tapered to 1/4 inch, and I just eyeballed it, mine is not a perfect transition since I'm working with hand tools and I don't even own caliper.

[@greasyfingerprints]

What are these quarter inch things you speak of?

[@gramursowanfaborden5820]

bigger than an iddy, slightly smaller than a bit.
