I assume you are talking about one piece longbows? 3Rivers has some very nice hard cases for both takedown and one piece bows. Here is the link for the deluxe one piece longbow case.
http://www.3riversarchery.com/Cases+Bow++DLX+Longbow+Travel+Case_c43_s193_p0_i5125_product.html There is a less expensive standard model too. You would want the shorter version of the case which is 69" long. That length would easily accommodate the longbows you mention, and would have room to spare, especially with the 56" bow. Almost 2 inches of the total case length will be padding, so the actual inside length will be around 67", leaving only a few extra inches with a 62" longbow, but around 10" of so extra with your Beeler. The extra room is not altogether a bad thing. You can buy or make a cloth bag (preferably out of fleece or heavy wool) that is about 4" in diameter and a foot long to insert many of your other archery accessories and that bag can be inserted at the top of the case before you close it up. Just be sure you have adequate padding between any hard accessories and your bow tip so you don't scar the bow.
Another option is to go to the store and buy some fairly heavy PVC or HDPE pipe and glue a plastic cap on one end and a plastic screw fitting on the other end and make your own case. You can make a handle out of any number of materials from packing tape or duct tape to nylon webbing or leather. I have personally found that a length of nylon webbing with short loops sewn at the ends and really strong electrical ties (like the size the police and military sometimes use as handcuffs) put through the webbing loops and pulled tight around the plastic case work really well and can be installed in a jiffy. You can build the plastic cases to any desired length quickly and for very little money, and they work well. Make sure you put some padding at the ends. I like to cut a 1 to 2 inch long cylinder of fairly firm foam rubber that just slightly larger than the inside diameter of the plastic pipe and carefully push it to the bottom of the case. I don't glue it, because I want to be able to replace it if necessary at a later time. I will cut a similar piece of foam for the top end which is a very tiny bit smaller in diameter than the inside of the pipe. This piece of foam can be glued to the screw-on cap because it will be easy to access for later replacement if necessary. If you want to, you can spray paint or dye the tube to make it any color you want. Do that before you install the handle. This may sound like a lot of work, but once you have the plastic pipe, fittings, PVC glue, foam, electrical ties and nylon webbing (I get all mine at Lowe's), you can make up the entire case in less than an hour, except for painting or dying it. Another hint, the easiest way to sew the loops in the nylon webbing is to go to a shoe store or an upholstery shop if you don't have a sewing machine that is up to the task, or get an awl from some place like Tandy Leather and sew by hand. Or you can get a grommet kit and use grommets to hold the loop. This isn't rocket science.
