First off, welcome. You found the right place to get all your questions answered. The Excalibur has gone through a lot over the years. First made in Canada, then Taiwan. Those were great saws. Then they went to China and became far less reliable than they had been. Not all bad, just not the same quality. With proper care and adjustment, they will last a long time. Look at the I. D. plate to see where yours came from. As for blades, any brand of 5-inch scroll saw blades will work but the preferred brands that most of us use are Flying Dutchman and Pegas. One of our members has a business, (Artcraftersonline.com), that sells both the Pegas blades and also the Pegas saw that is very similar to the Excalibur but a much better saw. The FD blades can be purchased through Mike's Workshop or Wooden Teddy Bear, both online sources. My preference is Pegas but many others are lovers of the FD blades. If you want to buy from a store front, look for Olsen blades. They are the best ones sold from storefront venders. Denny Knappen who is a member here owns the online store I mentioned above, is where I buy my Pegas blades. His prices are the best and his service can not be beaten. Another suggestion,, if you are going to get serious about scrolling is to upgrade the upper and lower blade clamps on your saw to the Pegas holders. They are an upgrade that can't be beat. I have them on both of my saws.
