I have just taken a chance on a B&D BD-339 Bandsaw off eBay and it arrived today and its a bit of a mess unfortunately.
I have no doubt that its salvageable but in its current condition I fear I paid over the odds.. But it was a gamble so I just need to move on.
The biggest problem is that the motor was hanging off and I wonder if this happened in transit as the seller didn't pack it particularly well.. The bolt was inside the saw and the thread on the motor has been torn out (Although if I am honest, I suspect its was like this before as there is no evidence of any thread material on the bolt).
I have removed the motor, and I think the best thing I can do is drill/tap out the hole to take an M8 bolt (Or perhaps an M7 (which I would have to source)..
But now I have it out, I want to service the speed control mechanism and don't have a clue how it works.
On the end of the motor shaft is a V-pulley and underneath this a large spring.. How exactly does this work? Does the pulley need to move up/down the shaft?
When its back together, I noticed when you turn the Rod, which is connected to the motor mount, it makes the motor move and I assume this makes the mechanism on the end of the motor shaft do its thing.. But I cant' work out how it works.
Can I also ask that the speed indicator that you see next to the power switch doesn't actually do anything? Its just there to show the position of the motor? Or as that in some way part of the mechanism.
Thanks in advance for any advice you can give.. I am still hopeful that I can get the saw working to a reasonable standard.
