When I was first getting into CNC machining as a refugee from 3D printing I didn't try machinable wax. I thought it was just a material pro-shops used for tool path checking. But then I found you can use it for direct production of excellent resin casting moulds, using a design approach similar to injection moulding. <br />There wasn't much "how to" on the web so I decided to make my own video so other people getting into CNC at desktop level can draw on my observations / experience. <br />If this video proves popular, I'll add videos on how to do the casting box, and show the process of casting the final product. <br />The objects being made in this video are for the Dremel Tool Carrier adapter (225 to 220) I've shown in another video in a 3D printed version. That item is available from Shapeways, but this version will be available from Ebay at a much lower price, since once you have a mould, resin casting is far cheaper (and better finish, and more material options) than 3D printing. <br />Machinable wax is now my favourite material for mould making. There are a few drawbacks / complications in its use against alternatives like tooling board, but its much faster and easier to machine, and if you stuff it up, you can always re-melt it and start again. Small mistakes can sometimes even be rectified by doing local welding or fills on a partly finished piece. <br /> <br />If you'd like to try this a project for yourself I can send you the STL files (no charge) if you leave me your email on the contact form link below. Bear in mind that the adapter threaded portion requires a little more effort to machine than the the other three parts shown in the video. It requires a 3 piece mould where I use cast silicon rubber for one part. This was a bit complex to show in a video, but if you want to do the project I can let you know how I did it - bearing in mind there's plenty of other methods to try. <br />If you have queries, or improvement suggestions arising from the video, please feel to post comments or give me feedback via www.highpaidhobo.com <br /> <br /> <br />If you'd like to do this project yourself, I can send you STL files of the 3D model.
