Machining parts from Delrin for ESk8 has worked quite well for me. From battery holders (no spot welding) to pulleys, Kegel inserts and various other items, Delrin has been great and is easy to machine. Machined part of my deck from HDPE and the enclosure from expanded PVC. All easy stuff to machine, probably don’t need anything larger than a desktop CNC. Also machined my own bushings… It’s been a lot of fun! Good luck!
Im a pro CNC machinist, i don`t know how much space you have but as soon as you setup a industry machine it will cost money. (space+electricity+coolant+maintanence) So the machine must be fed.
I personally have a DIY CNC machine… i would suggest you to go that way if you don`t want to produce parts everyday.
I have a shapeoko 3 and have been really satisfied with its abilities for the price. They offer a few models starting around 1,500 and just announced this new model that looks really promising: Shapeoko HDM (PREORDER) - Carbide 3D
I started a new hobby by converting a manual machine to cnc. Which was fun and educational but also time consuming and frustrating sometimes
Anyway, if you just want to make parts or protypes without much hassle, buy a complete machine tool or diy kit.
A router is pretty great to make simpler parts, like a workbee or a shapeoko. @Lee_Wright plug:
Ive also considered an omio x6 router in the past but decided to go the diy way with a hobby manual mill, which would allow me to make more interesting parts.
That thing doesn’t look very DIY except for some pieces. Got a parts list? My DIY is almost there. I just need to have the plates machined to get her going.
