Not so hard with a table mounted Jaw chuck. Milled one side and then flipped the part in the chuck and milled the other. And I carefully adjusted the program while checking the OD fit with a micrometer and a bearing for test fitting to make sure the OD of the adapter was good.

Any updates on the adapters for using riptide bushings on Matrix 3?

Super curious what CNC system you use? Entry level machines here tend to be Tormach’s or manual mills with CNC conversion kits- ‘Precision Mathews’, Harbor Freight ‘mini mill’, and etc. Openbuilds has an interesting mini mill that I’ve been eyeballing but I’m not sure how effective it would be.

Still working on the first batch of motor mounts and some custom orders atm. Once they are down I will machine the first prototypes.

You can find some more info here: Brian's workshop (CNC Mill build) - #12 by Creavenger - Workshops - FreeSK8
The machine I have is similar to a precision mathews manual mill like you mentioned, I converted mine to CNC too. If you are starting out I would recommend looking at the Langmuir MR-1, it looks like a capable machine and I would definitely consider it if I would start over. The price is pretty great for what you are getting, one downside I found though is that you cant easily swap tools but that can be modified.

So I finally have some pulleys and belts available, slowly building up the essentials on the website. These will be compatible with the Sceptre Motor Mounts.

Beautifully done machine. Thanks.

In case you have some free brain to spare, what would be your pick on this ?
just discovered it today and I love the idea, maybe it could be somewhat more design tho

Think something like this would be best in plastic, since most people dont want to scrape a fancy cnc part. Looks like they used some kind of lexan here, I can lasercut something similar for anyone wanting something like this.

Do you have some serious fiber laser ?
150W CO2 laser. Would love a fiber laser though since it would be a bit better for engraving anodised parts.
yeah, so no aluminum cutting, that would have been much less machining than cnced parts

Yes, I actually worked with a local waterjetcutting company already to precut some stock so it saves a lot of machining time. But in the end the time gain vs the costs is marginal.
Ah yes ? I don’t have more than hobby grade machines so I’m far from machining metal,
but I’ve had a couple of parts made by Chinese prototyping companies: usualy each aditional dimension you work in is a significant step in price.
Like laser cut aluminium is easily half or a third of the cnc milled part for a minimal design difference
