I've had success on the straight cuts with a table saw using a 60 tooth combo blade. Don't forget a zero clearance insert and "Table Saw cuts finish side up - Circular saw cuts finish side down". For tight spot cuts how about the cutting attachment on a fein multimaster or rockwell multi tool. I've had good results with mine. Staining is a chore in itself. The prep work is the most laborious. Although not a method I recommend for safety reasons, but a method used widely in days gone by, is fuming. If you are not familiar with the process, don't even consider it. But it was a way to "stain" large areas of exposed wood in a short period of time. Again, it is a chemical process and can be very dangerous. But boy, is the result stunning. Cost effective adjustable bar stool? How about a threaded wood center post?
