Man, it's the best small setup that i've seen so far... thank you for that video

@GraceNoteForge Год назад

Thank you for watching 😁

@Devi1D0g04 10 месяцев назад

Thank you for this. I have been looking for something like that, which makes vacuum casting so much more affordable.

Great video i really enjoyed this nice build. It is not easy to make one I've been racking my brain on how to make one what a great design. You do some incredible stuff. if you dont want to do any welding They sell this stuff called sanitary tubing . You can buy a 4" diameter spool and end cap for the bottom. drill and tap a 1/2 npt on the edge of the end cap. Screw in a boared npt to swage fitting. Take a peice of stainless steel or copper pipe and drill tiny holes towards one end of the pipe and put a swaged plug on that end. Put the capped end inside the chamber and stick the other end through the swage fitting out of the camber and bend it at a 90°. Think of the pipe like a snorkel inside the chambe This way no molten metal can get to the vacume in the event of a blowout. From there Put an end cap with a drilled hole at the top if the chamber and you are golden. Super simple no welding and under $120. If you want to use a perforated flask no changes are nessary use a 3.5" perforated flask it will sit perfectly on your flange gasket for 4" pipe, just make sure the spool you bought is long enough. And use high temperature seals. It is not hard to make a chamber that can handle a 8" long flask. Or bigger Or you can buy 6"d 12" long pipe like me so you can use 4" & 5" flasks. You can also fit a 4" flask in for the degassing part. Glacier tanks sells a special 6" end cap with a 4" which is perfect. At some point I want to put a band heater on mine wrap it in a ceramic blanket and skeet metal with a hose clamp around it. Slap a PID control at 900° and it would be perfect and at the same level as a $10,000.

Fantastic setup, wish you had made a video like this a couple years back!

@GraceNoteForge Год назад

Thanks! I wish I did too lol

@nathaneldridge157 Год назад

You just saved me about 1200 bucks lol. Definately gonna give this a try as soon as I have some space to work

@GraceNoteForge Год назад

Happy to help! Hope it works well for you 😁

@burningbacons3099 Год назад

Wish this was released a week ago hahaha I just spent $1500 on a kayacast

@drumhailer547 4 месяца назад

Yes ! I just bought a vacuum chamber and planed on making a modification like this to put through the stainless steel side then i can cap it and still use it for wood stabalisation and degassing investment 🎉

@shawnwillis7561 10 месяцев назад

Awesome and simple. I think I'll definitely try this set up.

@matthewbaker2573 2 месяца назад

for larger flasks, just get a large enough metal pipe and weld a holed disc onto one end so the flask edges just sit on top. this could be easily lifted on and off what you have already built. a few clips to hold down would be advisable =) you can make multiple sized chambers for different sized flasks

@brianfilkowski 7 месяцев назад

Very cool

@noviceartisan Год назад

Nicely made! WIth a little larger pipe you could make a chmber for perforated flasks (I did xD). I used rtv silicone gasket to seal my welds instead of JBweld, and the bottom of the pipe is a sheet that's just tacked on in a couple spots, and then the silicone gasket material all arorund to seal it. That way when theirs a leak, it's not too tricky to remove it. If I'd used a pipe with a screw cap, it'd have been a lot better, just couldn't find one in the size of the flasks I use

@dickmorris6310 Год назад

An inline trap such as the one under your table is a must. I lost a high quality vacuum pump because I didn't have one when the bottom of a flask broke when I applied applied the vacuum.

@JackTheAwesomeKnot 8 месяцев назад

I would use a piece of steel wool along side your 1/16th filter, it would catch way more metal without much loss in air removal time. Edit: I remembered just after that steel wool is flammable... so many not a good idea to use it as the filter..

@solarflare8806 8 месяцев назад

I was thinking the same thing.

@paulmanhart4481 Год назад

Good job. A gauge is handy in checking for leaks. Just fyi.

@DontCallMeGarage 6 месяцев назад

welding that heavy of plate with a 110v welder you should pre-heat. it will help a lot.

@GraceNoteForge 6 месяцев назад

Thanks for the tip! I'll try and remember that for next time

@SM-coco 11 месяцев назад

It's really interesting and you are very talented🤪!! Is this working well without any issue when casting? Looks very compact, too. Great job!!

@GraceNoteForge 11 месяцев назад

Thank you so much! 🙏 This setup is working great for me so far. No issues with casting and easy to use 😁

Add an Air filter above the metal filter for better recovery of metal

@inkstainedsink6060 8 месяцев назад

Awesome. Are you able to degass your investment on that rig with a dome or do you use a separate vacuum? I'll be building one shortly and this design really helps me. Thank you.

@mattooi4322 3 месяца назад

Love your creativity and DIY spirit. What burnout furnace do you use?

@GraceNoteForge 3 месяца назад

Thank you! 🙏 I use a Paragon SC2 burnout kiln.

@danielcarey3165 8 месяцев назад

cool video cheers - ive started making a version but wondered about the need for an inline filter to protect the pump in case of blowout. can't find any information about anyone online using one. Is this something you use? maybe im overthinking it all

@LogicCaster Год назад

Could you do a review on the furnace, vacuum pump set and all the ebay/amazon stuff you use? Im thinking of giving the budget “ebay lab” a go.

@GraceNoteForge Год назад

I don't have a review on the vacuum chamber yet but I did do a review on the melting furnace a while back 😁

@LogicCaster Год назад

@@GraceNoteForge Oh you did! Great video too, ill sub in anticipation of the vacuum pump video my man!

@norcore8504 Год назад

4:05 use higher voltage

@AndyRRR0791 6 месяцев назад

You should try using the vacuum the draw the aluminium up into the mold instead.

@stringerb8618 10 месяцев назад

Hello Sir I have been learning from you and your skills thanks for the work you do for us. I was wondering if it would be possible to make a pressure chamber attachment that can push molten further into the small crevasses of a mould to achieve better quality result ?

@GraceNoteForge 10 месяцев назад

That's an interesting idea. I don't think I've seen a system like that. Steam casting uses a similar technique to forcibly push the molten metal into the small cavities, rather than pull them with a vacuum but I'm not sure if the result is any better or worse.

@oldkingcrow777 9 месяцев назад

@@GraceNoteForgeyeah it seems like the whole point of thr vacuum casting is to get those fine details, eliminating any potential need for pressure to push it in. Thanks for this video BTW. Started messing with pewter before I do bronze (have a large furnace I successfully melted with but I'm taking it slow with the actual pouring) and finally accepted I need a vacuum cast. Didn't wanna spend $800 on a side quest

@oweshkhansoni8848 Год назад

When you are going to make for big flasks and i have a question about vaccum pump supposed if we work on big so did we need another pump for it..

@littlehills739 Год назад

look into some ultra thin cut off disks :)

@jchunick 9 месяцев назад

I wonder if you could use the Bernoulli Principle to effectively do the same thing?... the question would be if it creates enough suction, I guess.

@givervelez8930 7 месяцев назад

Para cilindros perforados por favor

@colethynne 10 месяцев назад

Great stuff. I am in the process of making one, but simply from the chamber shown at time stamp 1:08. It’s already a completed unit I just use a hole saw and drop the flask into place. Was there a reason you decided not to try that?

@GraceNoteForge 10 месяцев назад

Thank you! I've heard that can work well too, but the main reasons I didn't go that route was because I wanted something a little smaller to fit right next to my furnace and I also didn't want to modify the vacuum chamber I had lol. One thing to keep in mind too is that the bigger the chamber is, the longer it's going to take to get up to full vacuum and every second counts. As soon as the flask leaves the kiln, it's losing heat. So finding a way to make that chamber as small as possible will help your casting results. 😃

@therealworldsociety42 3 месяца назад

Can vacuum casting work if the whole mold is encased inside a regular steel vacuum chamber? Or will it pull the metal out of the mold as much as into it?

@Ome_Rashid Месяц назад

Hey, i’m new to casting metal and i’m wondering what the pros and cons are of using a solid wall flask instead of a perforated one? is it just more efficient in getting the air bubbles out in a vacuum, or am i missing something else?

@treyy6936 9 месяцев назад

Would you ever consider selling these? Would totally buy one.

@DaniloPappalardo-wf2xl 3 месяца назад

I don't understand how the air is sucked in or the plaster cast has no holes in the lower part which is attached to the vacuum pump

@thetinman5297 3 месяца назад

Because the plaster is porous enough that air will suck through under a vacuum but not metal

@dinitris16 19 дней назад

Couldnt you just use your vacuum system, drill a hole in the lid, use the metal plate and the ruber to seal it and put the mold in or on top of there? Cause thats what i wanna do for my dyi system in a bit.

How much vacuum pump power

@GLIDERR 5 месяцев назад

is there a way to do this without welding? i dont have the tools and dont know anyone that does, welding isnt super common in the uk.

@GraceNoteForge 5 месяцев назад

I've been playing around with a design for a new vacuum casting table that would make it more modular and doesn't require any welding. The basic idea would be to sandwich the pipe in between two steel plates using some threaded rod. Then, some high temp rubber gasket can be used in between those layers to seal off any gaps. I'm still a ways off from completing this project but I'll be sure to make a video on the process in the future!

@mustafa501M Год назад

You think this could be scaled for larger investment casting?

@GraceNoteForge Год назад

I don't see why not. It just depends on the size of the flask I suppose.

@vetsen Месяц назад

Where did you get the small plastic filter on the ball valve side?

@GraceNoteForge Месяц назад

That actually came with my vacuum chamber (I should have mentioned that in the video). If you search "vacuum chamber filter", you can find them online.
