Gutter leaf blower fix

Gutter leaf blower fix
Bought a Worx Gutterpro WA4094 gutter cleaner at the sametime as this Black & Decker 20v LSW321 leaf blower. Figured I'dhad enough ladder climbing in my 86 years so decided tosplurge and go modern. I read all the reviews and couldn't finda gutter leaf blower specific to this B&D, and the description ofthe Worx Gutterpro said "Universal fits all major brands" so decidedto take a chance.Well, received both today and all looked good until I tried toassemble the Gutterpro. It was supposed to be "Universal fits allmajor brands". Well, it doesn't fit my new B&D blower, so it ain't,no way. Dang!Apparently the mfgr's are relying on the canvas bag (enclosedwith it) to do this, but it can not work on this little B&D. For onething the bag's too big. And no place on the blower to connect a strap, bungee cordor rope. Also, the hard plastic nozzle in the bag is about thesame diameter as the output nozzle of the blower and when thebag is pulled on over the nozzle, it won't pull up tight enough tokeep the bag from acting like a wet noodle. Impossible for oneperson to use.Sadly, I decided to send it back. Cancelled the purchase, wentthru the process. The Amazon software was very helpful, says I'llget a refund, etc.While packing it up, I took a closer look at the canvas bag.Turned it inside out and saw that the bag was being held onto theplastic nozzle by a cable tie. I found that if I pushed the leafblower wand of my new B&D blower into the bags nozzle it wouldgo in over half the length of the wand and in that position it wasvery tight. I then pulled the wand out, clipped the cable tie, used a hacksaw to cut it tothe length I wanted, applied some JB Weld epoxy on it for tight sealing andshoved it as far onto the stub of the wand as it would go. Voila!Simple, and I think it'll be very ridgid and all of the pieces of theGutterpro will snap on as they were intended to.Don't yet know if the B&D blower will be be strong enough, but we'll see.I'm going to try to upload some pic's with this. We'll see how that goes.Keep in mind, I haven't tested this yet, I'll let the JB Weld set tilltomorrow or the next day before testing. I'll try to get back andgive the results once that happens.This probably won't be a fix for everybody due to the differentconfigurations of the many blowers, but it's quick and simple,almost anyone could do it if their existing blower wand will fitinside the bag's nozzle.Update: I'm pleased to say this works just fine. The little blower is just strong enough to lift the dried leaves up and out of the gutter (didn't blow all over me) and it's light enough for me to handle with at least 3 of the wand extensions being used (maybe with all four), but I only needed three. Did the whole house in less than 30 minutes instead of two hours and best of all didn't have to carry or climb a ladder!
