Metal Casting at Home Part 24 Solving a Mould problem

[myfordboy]

See video 24. The pattern is not cut in half after it is made. It is made in two parts throughout.

[fly2000jtb]

Which video do you show how you cut these parts in half? every time we try the cut is wavey even using a scroll saw? any advise, we have seen all your videos but dont remember the one with the cutting? Fly2000jtb Joseph T.

[yagere92]

Is it possible to use that greensand again and again and again..?

[myfordboy]

@yagere92 Yes it can.

[stillbashingmetal]

Captivating from start to finish. Another great video. Never get tired of watching your stuff. Thanks very much for the time and effort you give. It's appreciated.

[kameleonvkci]

I liked that you showed failure part too. ;)

Great video

[TanllwythDaf]

Thanks for sharing the entire series, I am looking forward to getting a furnace set up and can't wait to get casting.

[bx2200]

Do you ever use an existing third-party part to create a split mold for a new, duplicate part? I'm interested in the repair and restoration of old engines, and I would love to see how that's done.

[myfordboy]

@bx2200 I used a Dinky toy racing car in video 17 to make 10 replicas.I cut the orgional in half to make a split pattern and filled the inside with car filler to make the draft required.

[MrInventWorld]

I love your videos. Thanks for sharing. And great job.

[shortfusedleathernk]

Great video, would love to learn how to cast stuff myself!

[gwheyduke]

@shortfusedleathernk May I suggest several books by Terry Aspin? They are TAB workshop practice series, The Backyard Foundry and "Foundrywork for the Amateur".

Both filled with illustrations and good information on sand casting.

[Dancerpro1]

How do you figure the amount of metal to complete the pour?

[myfordboy]

@Dancerpro1 Experience, or you can  put the pattern in water and see how much is displaced, then measure the volume.

[FireDropTechnologies]

Laundery starch would be inexpensive.

[FireDropTechnologies]

I have never tryed it? But wouldthink that starch could be used ,

in a water base for the same purpose when baked.

[FireDropTechnologies]

See? you use a differant teqnique than the one I was taught,

in the fashion I was taught? One uses Lindseed oil to bond

the sand, and then bakes the mold till it sets hard, before

removing the Mould blanks, It alows for much more intricate,

pattern, with less chance of sand failure. Much like the

Porciline dipping method.

[cncnewbie]

Yet another excellent video! With regard to you and Tubalcain and your comments, you two exemplify engineering craftsmanship equally from both sides of the pond. The internet and Youtube have a lot to thank you for! Keep it up!

[landloper1986]

question. are you able to reuse the sand, I would think so, but I honestly don't have a clue

[myfordboy]

@landloper1986 Sand can be used over and over again.

[landloper1986]

@myfordboy thanks. thought so, man I can't wait to get a go at that. starting from scratch though. I need everithimg. from a furnace to safety equipment, to scrap metal for melting. this is going to be at least a decade work, to just start smelting and moulding. but itll be worth it. learning tonns of stuff from you guys. thanks for that

[MGARestoration]

Using the screws was a geat adaptation. Great problem solving idea!

[tsukubadiver]

Thank you. I teach and among the many "lessons" I try to teach is that failing is a additional chance to learn another option for success.

[Axbent]

Would would have thought something like hair or plumbers yarn would be used to reinforce sand in awkward places. 

[Axbent]

I was to use my lathes as inspiration for YT name, it would either be SherlineBoy or EasyturnBoy. Both sound like the belong in Amsterdam's red light district.

[mackme50]

Thanks, I really enjoy your vids.

[TheSuperFungus]

I love watching a successful cast come out of the mould :) Thanks MFB :)

[andytysn]

Thank you for another great video, It comes at just the right time for me (I am having a similar mould making issue, I like the screw idea and can't wait to try it!) You and mrpete are the best!!!!

[bx2200]

What is the ID of the feeder and riser tubes? It looks to be about 1"?

Many thanks for yet another well-done and instructive video!

[myfordboy]

@bx2200 Its about an inch. Its a 22mm ID copper pipe

[yetshi]

love the videos.

where did you get those pin locks for the cope and drag?

[myfordboy]

@yetshi They are home made from modesty blocks. A few people have asked about these, perhaps I should do a short video on the construction.

[myfordboy]

@yetshi I have added details at myfordboy.blogspot.com

[LmarvinM]

Thanks love your videos and @mrpete222 by the way!!

[marcibb]

Thank you for an other great instructive video

[express375]

Lovely job

[brandoc1950]

Another great educational video, thanks for uploading them. BTW, which motorway do you live next to? :)

@mrepete, myfordboy's video's aren't any better in my view. You both do great video's but with different presentation. And I'd be gobsmacked if myfordboy spoke, and think I'd gone deaf if mrpete didn't. ;)

[theteewording]

hello,

where u buy the sand or u make it at home?

greetz from germany :)

[myfordboy]

@theteewording Sand comes from a a foundry supplier.

[MrLeonard55]

I really enjoy your videos.

[magneticatastrophy]

Clever way to fix your mold. I enjoy your videos.

[mrpete222]

You are quite ingenious and your videos are better than mine. tubalcain

[myfordboy]

@mrpete222 You have more views than me though! Thank you, that's quite a compliment from a respected engineer like yourself.

[gohuskies583]

@myfordboy

Both of you are putting out quality stuff and we have all learned much from your videos. What makes them so enjoyable is that you enjoy sharing your craft with the world. Keep up the great work!

[Morkvonork]

@myfordboy I think its because a lot of people who have a little machine shop would never think of starting metal casting on their own.
