Non-Standard Miter Slots - This one is a downer.  One of the primary advantages of having a table saw is access to jigs that expand the saws functionality.  This is a major issue if you plan on buying after market jigs.  Given that we are limiting the cost of this buildout to $500, I am guessing that after market jigs are probably low on the priority list.  Your going to want jigs once you start researching what they enable you to do, my advice is to build your own - there are plenty of plans online.  
Steve Ramsey makes woodworking fun. His YouTube Channel, Woodworking For Mere Mortals Building, shows Steve making cool stuff in his garage in Marin County, California. From games and toys to special holiday projects during his 12 days of "Craftmas" (wooden snowflakes!), Steve consistently puts out new DIY woodworking videos and projects every Friday.
Turn leftover wood or old pieces of furniture into DIY reclaimed wood projects! Wood is one of my favorite materials to work with. The possibilities are endless and they give such a homey and cozy feel to any rustic home. My husband, Dave, and I sometimes even go the extra mile and carve our initials on a little spot. It’s our own way of making our DIY project even more personal! Here’s a list of some of our favorite DIY reclaimed wood projects!   
Hardwoods come from deciduous, or broad-leaved trees, as opposed to softwoods, that are harvested from from evergreens. In general, the lumber derived from hardwood species are typically harder than softwoods, although there are exceptions (balsa wood is very light and soft, but is considered a hardwood). Most hardwood tree species lose their leaves in winter, and generally offer a much wider variety of colors and textures than softwoods. Typically, stock from hardwood species are a lot more expensive than those from softwoods.

Perhaps the most satisfying move I made was to automate the dust collection system. I used the iVACPro system to link all machines to the dust collector. When I turn on any machine in the shop, the dust collector fires up and whisks the dust into the bin. The system also has a programmable delay to allow the dust to make it to the bin before the dust collector shuts down. I set my system for a five-second delay. The system works flawlessly for my band saw, planer, and router table at 115 volts, and also my table saw and jointer at 240 volts. 

If I had it to do over again, I would stick to an entry level miter saw and table saw until I had both the funds and need to upgrade to more capable saws.  Because of this, I'd stick to the two saws we looked at in the $500 build: ​The Craftsman Table Saw for ~$150 and Hitachi 10 inch Miter Saw for ~110.  These two additions bring our running total to just over $500.  
Raw material is a concept. A concept that we describe as any material that has yet to find its final home. It is a material that is en route to becoming something interesting, creative and more permanent in the world. If it has yet to be worked and transformed to create a unique piece of woodworking or artisan craftsmanship, then it is still raw to us.
Use the square and position the pivot point onto the board top and slide the square up to the 5 on the line up “COMMON TOP CUT” outside the board. Mark the line as for the angle. After first angle is cut, measure the rafter length from the tip cut to get the seat cut measurement. Mark the seat cut and place the pivot point onto this mark and do the same step to get 5/12 angle. From that angle, measure up 2 ½” and make the line.
A layout square, or combination square, comes in 6” and 12” sizes. Most woodworkers use the 6” model, simply because it’s easiest to carry around. Also, most of the stock you’ll use will be no bigger than 6” wide, so 12” is overkill. The layout square is a triangle that you can use to mark square cuts on stock. Once you measure the length of the cut, you line up the layout square with the edge of the board. The short side will give you a straight, square cut across the end grain. You can also measure off angles with the layout square. This helps when you’re trying to measure for a bevel on a table saw, or marking a cut for a miter saw. You can even use your layout square to determine an existing angle. Just be sure to buy one made of metal. The plastic ones are not only fragile, but they also can warp, making them pretty useless.
