Ultimate handyman have just put out a great video on adapting your mitre saw to be able to be used with any leg stand:
It’s a common problem with a lot of products, not just mitre saws, that only after buying a product you realise that you need to buy the accessories and consumables for the product that are branded rather than third party. This usually adds unnecessary expense, and it can even be hard at times to source what you need.
As you can see it the video, the Evolution Rage 2 is able to be fitted to another type of leg stand using this “adaptor plate” technique.
