Scratch Build – In Progress Project: Blue Horizon - "MOTY" Nominee

Being creative in the kitchen just took on a new meaning Should get that on the food network lol. What kind of rpms are you looking at when milling wax, also does it require any special bits or should I say end mills?

 

Thanks p0Pe

Yeah its awesome stuff

Thanks Talladega , Nice

Yeah I know how to sandcast, but I don't have the equipment to do it myself , so I'm just gonna make the mould. Although I haven't decided yet whether I'm going to sandcast or Lost wax cast.

Yeah lol , yeah just normal end mills, heres the specs:

Well that's just downright awesome with the lost wax process. Really looking forward to what you come up with.

What bits are you going to make with this process, and how much does the wax and getting it sent off and cast cost?

 

Thanks , I'm going to be making the top of the case with the casting as it has a compound curve on each corner. The wax cost £15 per Kg for small quantities, or £7 per kg direct from the suppliers but the minimum order is 15KG. The sandcasting cost is based on weight of the aluminium used, the top of this case will be around £30, but it depends on which company you use. I can get castings made cheaply as my father has a business account with a casting company.

You have to make the form to create the mould as well, because most sandcasters only do sandcasting they don't create the form to create the sand mould. I'm not sure about the cost of lost wax yet, I'm gonna find out soon though.

 

Nice to see you made the block how you wanted & the shiny blue helmet , nice progress .

 

Don't forget to account for shrinkage.

 

Repp'd for future awesome.

 

Yep, thanks

Yeah, this was my second attempt at the wax moulding as the first one I made shrunk loads, it was on the previous page of my thread.

Thanks Cheapskate


I'll be machining the wax tomorrow

 

I was thinking more about the cast aluminum.

 

Ah right, yeah I've scaled the 3d model to account for shrinkage, thanks for the reminder though

 

I ve been watching the whole process with the wax but I am so curious to see the end result, I have no clue what next is but I am sure I will be amazed once again! Bravo my friend!

 

Thanks Alex



Heres the pics of the CNC machining:














This isn't the entire top of the case, the wax mould will be chopped in half.

All it needs now is too smooth out throughs ridges. Heres all the remains, its like wax snow :



I was gonna make a video of the CNC in action but my video cam's battery died so I'm gonna make the video when I do the next bit of CNC'ing.

 

using wax ^^

I love it

By the way how strong is that wax?

 

I would compare it to acrylic, its pretty strong in thick peices, however its quite brittle, unless its in a large block which then its incredibly strong. I tried to break the blocks apart with the back end of a hammer so I could melt them but all it did was chip the corner a bit.

 

I assume the wax remainders can be recycled into new wax blocks?

 

Yep, I'm gonna melt them down again in the fondu cooker

 

Someone finally found a good use for a fondu cooker!

 

Yeah lol

 

Improving skills : Completed!
Just keep on modding Keir

 

lol, thanks Alex


Heres the cnc machine finishing up with a small stepover:



The sides are now much smoother:





Next up will be to sand it down then do the inside.

I've got a video too, which I'll upload in a few min, it could take quite a while though as my upload speed is crap.


Edit: Actually I'll upload it at college tomorrow its gonna takes hours on my slow upload speed
