NEED BAND SAW BLADES FOR MY OLD BLACK & DECKER 7 1/2'' BAND SAW . CIRCUMFERENTIAL LENGTH WOULD NEED TO BE APROXIMATELY 53 INCHES .I FIND LOTS OF 56 AND 59 INCH ,...ALL TO LONG . WHERE CAN I BUY THE 53 INCH CIRCUMFERENTIAL LENGTH NEW BAND SAW BLADES ? .

I get my band saw blades on www.sawblade.com . I cut both wood and metal. I'm using their Carbon and Bi metal blades. Give them a call.

The blade length is probably almost 100" , but I suggest you try to calculate the length , try this method Calculate Belt or Band Saw Blade Length VintageMachinery org

There are many reasons why band saw make noise. Here's are some "few checks" to do
1. Run the band saw without blade.
2. Run with a different blade.
3. Run the motor alone.
4. Check the bearings.
Another thing; incorrect speeds and feeds can cause noise and vibration.
Regarding about opening the motor, I can't help you with that. Try to check any other band saw motor manual reference.

I have Trajan 7x12 band saw, no vibration or noisy at all, I use Haltbar blade from sawblade.com

There are few reasons why blade jumps off, you may have a poor weld on the blade. Tension could be too tight or too loose. Make sure that the blade tracks properly. I advise you to watch videos about tuning up a band saw or check some informative blogs on bandsawblog.com. I purchased my blades on sawblade.com , check them out if you need any.

Where are you located? Sawblade.com is an online blades supplier , they custom weld band saw blade to your required length.

Just Google "band saw blades 52 3/4" for more information than you want. Most woodworking supply stores carry them.
Here's one: http://www.toolcenter.com/052_75_Band_saw_Blades.html

Open the case and look for stray wood pieces. Check the bearings for both wheels. Check the mounting of the lower wheel to it's shaft. Operate the saw by hand until the problem is fixed. Good luck!

You can det it @ www.grainger.com. hope this helps
