Delta 50-760 collection bag band clamp

[John Loftis]

Hi folks, I could use a little help. As many people have noted in the past, the band clamp that holds the bottom plastic bag onto the Delta 50-760 dust collector is improperly sized. The latch is either too loose at the second latch position or way too tight at the third. Like a meathead, I forced the issue and broke the latch. It doesn't make any sense for me to buy an OEM replacement part, since I'd be spending $30 on something that didn't work properly in the first place.

So what to do? I tried a bungee cord, but it leaks badly where the hooks meet. A friend suggested getting a big worm drive hose clamp, but I can't find those anywhere (I've checked Grainger, Rockler, HD, Lowes, Amazon, Grizzly, and half a dozen other places). I thought about one of those nylon 'come along' band clamps that we use as hold-downs on our pick-ups, but my friend thought that would leak at the ratcheting mechanism. I wondered about a flexible magnetic strip, cutting it to the exact 20" circumference and sandwiching the bag between the magnet and the steel ring protruding from the unit. But I'm not sure if a magnet would be strong enough with 30 lbs of collected dust and the air pressure of the unit itself.

Any other suggestions or ideas?
If not, does anyone know where I can grab a large diameter worm drive hose clamp? I could always gang up a couple together, I guess, but the more Sanford and Son I get, the greater the chances this thing will spew dust at me.
Thanks much,
John
