    What are the tools and machines did you use and how much is each for the tools and machines and what was the measurements for the pink foam and the wood. Or do you have videos explaining

    There are a lot of metal casting videos as of late on KZread. This video is among the best based on a large sampling. Many people wish to make videos and appear as knowledgeable and they often give inferior and flawed instructions that will result in a lot of wasted effort and potential for long term flawed and erroneous methodology. This is a great video for 'small scale lost plastic 3D printed model metal casting' and offers good instructions and sound methodology.

    Hello, great video! Quick question - how come you used two bearings opposed to just one? (to get more shaft engagement b/w the bearings and the rectangular "shaft"?)

  • @Grunblau
    @Grunblau13 күн бұрын

    Thanks! Two bearings limit the play that a single set would have. If you cut a section through the shaft you would see four bearings in the section rather than two. The further these bearings are apart, the more resistance to rotation there will be. -|:|- vs -|:|-|:|-

    I don’t generally entertain commissions… I get a lot of requests and they rarely go anywhere after I quote the work involved. The best I can offer is putting up enough info for people to pursue their own projects. There are a lot of ways to approach the part you reference that might include investment casting. Most likely it would be best to ask a machine shop that would produce it from billet aluminum and use steel inserts for what look like vacuum ports (not in my wheelhouse). Hope this helps!

    Make sure the bottom of the pond is level and adjust from there if it isn’t with sheets of pond liner. Then after placing the base, check the rim as best you can with an 8’ level. Install the bowl and check again. Could ultimately shim bowl too worst case…. Got pretty lucky in this case that the pond contractor had made the bottom of the pond extremely level!

    Aluminium is my favourite metal, aluminium 7075 is allegedly stronger than most types of steel alloys. It's usually in the airspace industry. I think cars should be made from aluminium or stainless steel because it won't rush, not even in salt water or after several decades.

    Forgive me for my ignorance; but I have a question. While your end product does look amazing, are you sure you aren't just doing double the work with refining the 3D print? I'm new to casting but am experienced in 3D printing. Are you sure the post processing of the print is really worth it? It doesn't seem to me the initial cast really showcases the processing you did on the 3D print. Or are you just very particular in your work?

    I still intend to do a run of these for Christmas presents… in that case I think I will be happy I have a smooth print. I will likely try to use Petrobond instead to reduce effort on multiples. With a smooth pattern, I could also produce a way mold for investment casting and do a tree of them at once!

    @Grunblau oh OK makes sense. I did my first casting from 3D print using petrobond the other week and it turned out really well making my own nordic gold for a coin. I was surprised that it did pick up the print lines, but still looks great with minimal processing.

    The biggest plague in any workshop is those pesky lower than 8 feet garage door rails. I have a 9'x7' garage door and my rails are at around 7'4" if I remember properly, so I cannot load a sheet vertically close to the door unless I dance with it (lower it to get through the garage door, than turn around and then raise it again.) and to unload it is even harder in the winter, as you have to take into consideration the 4' you need to get it out of the storage system, which means you then need a 8'6" diagonal clearance at minimum. This is a very clever idea though, putting the sheets at an angle to reduce the footprint... still an issue if you have a garage door in the way though :(

  • @Grunblau
    @Grunblau2 ай бұрын

    This storage was primarily to store thin sheets for a vacuum former. If you look closely, I think I acknowledged how much floor space it takes to get it out of the system as a lot of people miss this. Same with ripping on a table saw! So far, it has been great addition to the shop using vertical space that is usually wasted. But this only works with a floor to ceiling of greater than 8’.

  • @PunkR0ckz09
    @PunkR0ckz092 ай бұрын

    @@Grunblau Yes indeed, you mentioned the footprint required to take the sheets outs on a regular setup. However, you didn't mention that you need an unobstructed 8+ feet of vertical space for your design to load it easily. In my example, I was refering to the tracks of a standard 9'x7' garage door, they are generally at around 7'4", which is lower than 8', which means it wouldn't be easy to load it... but still doable, need to angle the sheet before loading it. This isn't specific to your design though, it was just an observation for others to think about as I was looking over other people's design to see if anyone had came up with a solution to less than 8' high tracks that gets in the way heh.
