Many tools & affordable options for this hobby, at least.
*This cheap but considerably good quality saw from Saker. They make many types of electric powered mini table saws, lathes, drill press. It's been a real nice set up for small hobby type stuff that we'd be cutting or sanding, etc.
*3D printers are pretty cheap these days depending what the user intends the end product to be. There are zillions of free designs that folks have made available on Thingiverse, Cults3d & other sites to upgrade these planes & especially 3D plastic parts to replace using wood & items that can beef up metal parts. The digitally modded or purpose made things you can make with a 3D printer that don't even need to be cut are pretty much endless.
*Higher end Dremel like a 4000 series that have quasi vice attachments among other feature that allow you to slide over wood as a router & other material to make straighter cuts without having to rely on our varying degrees of steady hands.
*Those wooden handle (preferred) hobby hand saws that allow you to change the depth of the blade & a metal miter box. Various sizes like the stuff you can get in the model section at Hobby Lobby or Amazon or Harbor Freight.
*Most 5-10-20w laser cutters are cheap today, as well, & can work wonders to mod or make replacement parts, but, again, if you're not taking an open free source design from an applicable site, you need to use a vector program to trace a rasterized PDF or similar file with the item you need & convert into a DFX file for the cutter to be able to read said file to be cut or etched.
Take a couple days & do some www surfing. You'll find whatever it is that fits your particular needs. I have all of the above & I've been really happy with what you can cut or design with these machines. Peace to you & yours.
Best regards,
