About this project

Introduction

The Revolver Multi-Tool is a lightweight and compact tool that is designed for your motorcycle. Significantly reduce the weight and bulk of tools you carry with the Revolver.

Features

  • High strength, heat-treated stainless-steel body, computer stress tested for lightest possible weight
  • Compact custom molded case can be opened and used as a "work-bench" on the trail with internal magnets hold onto nuts and bolts so they don't get lost in the dirt
  • Tool is held in place magnetically for quick removal, no strap to fuss with
    • Room for extra tools like pliers or a spark plug wrench
    • Several ¼" bits that fit most bikes; all the Torx, standard flat, star and hex bits and high quality Metric sockets included
    • 27mm axle nut wrench gets rid of the large bulky, heavy wrench required to change a tire
    • 13/16" spark plug wrench fits most 2-stroke bikes
    • First component of the BKE Racing tool system
    • Mandatory bottle opener, it wouldn't be a multi-tool without one!

Project History

I have been riding motorcycles for many years and have always been unhappy with the amount of tools you have to carry. The weight and bulk was excessive and I was always trying to come up with a better kit. The idea was to take only what you need and yet make sure you can do almost anything you might need to do on the road or trail. Some of the multi-tools available for bicycles seemed like a good idea, but they simply were not robust enough for bigger machines and many of the tools had no use on a motorcycle. There was really nothing available on the market, so I decided to fire up the CAD software and see what I could come up with.

At that point, I was really only trying to come up with something that I would use. I was looking at the various rapid prototyping systems that allowed me to quickly and easily get one or two copies of the tool in metal; something that would actually be strong enough to be useful. As with most projects worth doing, it quickly became apparent that in order for this thing to work it had to be done right. No 3D printing system would directly give me the part I would need. I determined that the best manufacturing method for a tool of this complexity would be investment casting in stainless steel. The project was no longer something that I could work on in my spare time and complete for a couple hundred dollars. It would require a substantial investment in time and tooling. After contacting a local investment casting company, they confirmed that they could make the tool to the required specifications at a reasonable cost. This is when point the project had become real; it was feasible to manufacture and sell these things.

After spending countless hours on the computer and many “virtual” design revisions, it was time to get something I could actually hold in my hand. Computers and CAD systems are great, but you still need to get the product in a form you can hold and feel. Computers models are terrible at giving you an accurate scale of what you are working on. I had several prototypes made using 3D printing in ABS. It is always satisfying when something you have been staring on a computer screen comes to life and actually works as planned. While not as strong as the real thing, the plastic prototypes are surprisingly useful and could honestly demonstrate how the tool would work, as you can see in the video above.

After a few minor revisions the part was ready to go into production. The next major hurdle was how I was going to fund the development and production. I can’t think of a better way to fund a motorcycle related project than website called Kickstarter! The Revolver Multi-Tool is truly a kick starter project. If successful, it will kick start BKE Racing and lead to several other great products in the development queue.

What the Funds Are For

The majority of the funds raised go into tooling costs for main body, bit holder and socket holder. These items require expensive injection molding tools. The molded case also requires custom tooling. A smaller portion of the funds raised will be used to purchase the minimum order quantities for the various bits and sockets.

Project Plan

All the major suppliers have been selected and are ready to begin working on the various parts. The project critical path is the body tooling which already has a tentative schedule based on the success of the campaign. Click the image below for a detailed production schedule.

Based on the current schedule, the Revolver should ship around the beginning of June.

More Product Information

The Revolver is the first in a family of products. For more information, see Mini-Max Chain Breaker and the Revolver Large Adapter

The Revolver has been computer tested to be light and strong with several FEA simulations.The Revolver has not only been cleverly designed, it's solid engineering.

Risks and challenges

The design work has been completed and a series of prototypes have been made to test the form and function. The Revolver has gone through several design revisions using 3D printing methods, and the tool has been proven to perform.

All the major components have been sourced and and firm quotes for the tooling have been received. Our suppliers are simply waiting for the word to start production.

The Revolver Multi-Tool is an innovative design, but the manufacturing technologies used are all well established and mature. There is very little risk to producing the product.

FAQ

  • Once you do get it in your hands, you will notice how balanced it feels. When used as a T-Handle, the extension goes through center of mass and also your thumb fits really nicely on the raised bumps on the top when used as a screwdriver .

    You might have noticed on the video, that those bumps form a wrench for the exhaust silencer. They also prevent you boot from slipping off when you give it a kick to tighten or loosen the axle nut.

    The whole kit is designed around 1/4" sockets and bits. There are two 1/4" extensions included, and short one and a long one. In the picture the long one has a 1/4" bit adapter on it, the short one is stuck in the socket holder.

    I have done a number of tests (and have a pile of broken stuff) to ensure the 1/4" hardware can take the torque required for larger bolts. It works fine for up to 60 ft-lbs, which is what the spec is for things like the lower shock mount on my Berg. It will have no problem for lower torque of a spark plug (12 ft-lbs)
