Metal Casting at Home Part 17. Ten Castings with a Snap Flask

[qotsaandsoadfan1]

Using your insulated pliers as a hammer, are you an electrician too?

[tgreening]

Your videos are extremely interesting. I'm curious how you make the patterns for the parts you are casting.

[myfordboy]

@tgreening I have videos showing the pattern making, Part 15 and 22.

[marcus3379]

Can the sand be used over and over again and is it expensive?

[myfordboy]

@marcus3379 Can be used over and over. Not expensive , you would have to check US prices.

[ebayisajoke]

waste of time.

[myfordboy]

@ebayisajoke Good guess.

[bgriggstwcny]

How long does it take the aluminum to cool so that you can open th emold.

[myfordboy]

@bgriggstwcny I leave it about 15 minutes.

[macybee1]

How did Dinky manage to produce this model so perfectly in 1930?

[kwikkeys3]

thanks for sharing!

[chopperboy25]

Nice work seeing your videos makes me whant to start casting

[twofoot65]

Please show the racing cars after they were completed with paint and tyres. I hope they ran at Brooklands! LOL

I'd also like to see how you built your snap flasks and other moulding boxes.

Cheers!

[myfordboy]

@twofoot65 I don't have the finished cars, they were cast for a neighbour. He painted them and fitted the wheels.

making sand molds hurt my back

[russtuff]

i just watched all 17 in one sitting. great videos!

[myfordboy]

@russtuff Better than TV ?

[hla27b]

@myfordboy Yes.

[refa42]

@myfordboy Way better. TV is useful only when it's connected to the computer.

Congrats m8....A1 work as always 10/10 :-)

[boomba3]

I thank the gentleman for this informative videos i`v learned a lot (Australia)

[robotpredator8]

hey my ford boy why don't you try casting alumium bicycle

[Axbent]

@robotpredator8 Aluminium bike parts are cold forged.

[robertsulley]

Another excellent video Myfordboy! How long did it take from starting the moulds to having the 10 lined up? It always amazes me that I watch the slag appear to be poured into the mould, but the finished item always turns out nice!

[myfordboy]

@robertsulley I made 12 moulds altogether no 11 is behind the rest, no 12 out of view. It took about 2 hours, allowing for a couple of failures and a tea break. Total time from start to finished castings, 3 hours.

[paprjam]

Very nice as usual. 

[BoingotheClown]

1920s style racing cars! Cool!

[CornishMiner]

Very interesting. How do you decide whether or not to use a riser when casting?

[myfordboy]

@CornishMiner I put a riser on the bigger ones. If the pattern is smaller than the feeder it doesn't get one.

[nebomatt]

nice style of cars

[fly2000jtb]

it is a trip how dry your sand looks but it works so well! we love the standoff pouring tubes you make as well. if that is what they are called we need to rewatch so we can get the name right hahahaa cool video as usual! joseph t fly2000jtb

[coriander2]

My wife asks me, " don't you get fed up watching him make sand boxes and pour metal in?" Ha,lol. No,never :-)

[myfordboy]

@coriander2 Ha!

[barumman]

Very good , nice quality video and subject. Best wishes from the centre of the universe.  :) :)

[Axbent]

Did the 6th come out right too?

[myfordboy]

@Axbent As you spotted I missed the pour on that one. It lacked detail on the underside. Lucky I actualy poured 11 !

[aleks138]

I have looked at many of your videos and I'm always afraid some sand might be broken loose while pouring and contaminate the part being cast. Is there even a possibility of that happening or is the sand that firm?

[myfordboy]

@aleks138 Sand is pretty firm. I have never had any fall out.

[gblpst81]

How can one determine the size limit for casting something in a snap flask? I'm guessing most of your larger castings run the risk of separating and possibly fracturing during the pour. Something small like this works well, but what's the limit? Great video, as usual.

[myfordboy]

@gblpst81 First time I have tried this method. If it were a large casting I think the pressure of the metal whoud collaps the sand unless the mould was a lot larger than the casting.

[gblpst81]

@myfordboy It seems that would be the case. There's probably a magic ratio of greensand volume-to-pour volume that can't be exceeded. That racecar casting was nice and small in comparison to the size of the flask, but even still the parting line left on the casting looked like it tryed to separate the two halves of the mould. I'd love to see the finished product once you're done. Do you know any details about pressure casting?

[jackkollan]

You make it look so easy. What type of sand is that?

[myfordboy]

@jackkollan Its a foundry greensand
