Ok so i was asked to show i make brakecalipers and discs etc..this is fairly easy to do and requires no preping when making molds with making 2 part mixtures.
The simplest are the flat brake calipers but if you would want a 3d caliper you will have to make a 2 part mold.

Heres what you will need :

This resin is a one to one mixture.

so once the mold is made ,simply mix the resin pour it into your mold,pour from one end slowly.The only mistake you can make is to not ensure that there aren´t any bubbles after you poured into the mold and waited till it settled.How i prevent bubbles but even then its not a sure thing is to pour the mix slowly into your mold and then i use a needle to stir the resin while its in the mold to shake up the bubbles.

3d molds are abit trickier you will need to make markers on your mold where the second half will be attached, so your second part fits correctly into your first part.I normaly put 2 objects like a tiny nut on one end and a bolt on the other.You have to wait till the first half is completely settled before doing the second half AND REMEMBER TO TAPE OFF OPEN GAPS on the part you are making a mold of.





This is simply my way of making and  it there are probably alot of  better ways but this was for me the simplist and less time consuming way.

Although I wasn't the one who requested this- heck I don't even know who you are, thanks for taking the time to show this off.

Just curious, where do you get your molds?

[mairandeddy]

Great results Luke    - but what about the moulds?   Are they just pressed - like into plasticine???

[VarioCam+]

The molds are made from putty, " Amazing Mold Putty" ..you simply mix the 2 part putty and press the part you want a mold of into the putty..The youtube clip shows how   ...its easyweasy.lol

Rather than start my own thread, I'll post this here instead.

Some of you may know that I am always asking for these front covers from the short tail 1/18 AUTOart 917K's.

What I want to know is basically, How do I make the silicone molds around the front cover I want to copy, Then how do I make the resin mixture?

Also would like to know  about buying the correct resins etc, And and the stuff to make the silicone copy. But I dont want to be buying loads of stuff, As the part is pretty small.

Really hope you guys can help me, I am bloody sick of searching for these parts now.






Or if any of you have the skills and would like to make me some, I will be very grateful  indeed.

Cheers

From the number of surfaces, you are looking at a two-part mold, most likely.

I am in the process of having some 1/24 scale parts enlarged to 1/18 scale through 3-D printing.  They were scanned, and scaled, and hopefully will fit the sample body I also sent to the "artist".

Wonder if you could have them 3-D printed?

[VarioCam+]

For a once off part ,that 3d printing is a great idea..making molds and then resin parts are time consuming and you wont get them first time perfect ,some parts will have bubble holes that will still need to be worked on afterwards.I cant remember but there was a guy here on the forum that helped me with a 3d set of wheels.He designed it and uploaded the file shapeways ,all i had to do was pay shapeways via paypal and the part was delivered to me.

Thanks for the help guys, Looks like I might just look into some 3D printing.
