About

T-Slot aluminum extrusions are great for building custom machines. We’re raising the bar by adding simple and affordable linear motion.

Our extrusion allows you to build machines that are modular and that bolt together with simple tools, and off-the-shelf nuts and bolts. No welding, drilling, tapping or painting is necessary. No need for special t-slot nuts. You can change and reconfigure your designs. You can even disassemble and reuse all the components in your next project.

We use simple cold rolled steel bar as a linear rail for v-groove bearings. Steel bars are readily available and MUCH less expensive then machined v-rails. The extrusion features slots that allow the linear rails to be press fit. All you need is a rubber mallet to install them. This further reduces costs by not requiring nuts and bolts to attach the rails, not to mention the time that takes. Unlike other extrusions that have extruded rails, the steel bars allow you to use steel bearings which would damage or wear down aluminum rails.

The slots are great for other reasons too. You can insert any 1/4 inch sheet materials including plywood and plexiglass, enabling you to easily create enclosures.

The system uses off-the-shelf 5/16 nuts and bolts available at any hardware store. Special t-slot nuts, used by most other extrusion profiles, are far more expensive and must be special ordered.

This profile is a beefy 40mm x 40mm, making it stronger than other alternatives with built-in rails, and it is also compatible with 4040 brackets and components from other manufacturers. There are hundreds of components and brackets that are compatible with this profile size.

We are super excited about this new profile. It is exactly what we need to start making the machines of our dreams. We can’t wait to get our first shipment and get started. We need your help to make that happen. Please join us!

Risks and challenges

The die for the extrusion is complete and we have a sample in hand. We have a small warehouse in which to take delivery and handle packaging and shipping. Designs for all parts are complete and we have US based vendors lined up. Remaining challenges for delivering on the Kickstarter include:

Shipping – we do not yet have a relationship with a shipping company and shipping the longer lengths in the Ultimate Maker may be difficult.

Delays – we carefully selected vendors for extrusion, plates and parts that are well established with solid track records. Still these relationships are new and any delays from, or issues with, these vendors may cause delays or even force us to find new suppliers.

Staff – there are only two of us, and we may need to hire additional help if we have a highly successful Kickstarter in order to get packaging and shipping done in a timely manner.

Beyond the Kickstarter we will also have to deal with issues like setting up an online store, getting a merchant account in order to process credit cards, and other typical business startup tasks.
