Glue for scarf on garden hoe
I have 3 hoes. I'm not particularly tall (5' 10.5"), but it seems that
they make hoes for people 5' 8" or less, because two of mine make my back ache, having to bend over so much. I scarfed an extension on one a few years ago and attempted a scarf on another hoe recently. The glue was 1 hour epoxy I've had around for many years to which I'd added some steel filings from my grinder. The reasoning was that the filings would make the bond tougher. Well, the glue failed while using the hoe, so I ground off the glue and tried another glue I had on hand, J-B Weld. I've had the tubes for probably around 3 years. The packaging claims it's the "Worlds finest cold weld" etc. Well, I'm using the hoe a couple of weeks after this and the scarf breaks again!! I never had trouble with the scarf on the other hoe. The angle is about the same, around 30 degrees (guesstimating), the length of the scarf being close to 3x the diameter of the handle. Better glue? Dan |

Dan I think you're asking too much for any glue alone. You could strengthen the joint considerably by wrapping in 3 successive layers of fiberglass + epoxy. Do NOT use any fast-setting epoxy when strength is important. No real epoxy reaches full hardness in less than 48 hours. I googled: long handled hoe and got quite a few hits. That's the better option, I think. |

I'd find a long handled hoe--- They are out there, just not at your big box store. But if you want to scarf a joint that will take that kind of abuse I'd start with a scarf 5-7 times as long as the diameter. Then I'd use Weldwood Resorcinol glue-- I did a scarf on a 30 yr old gun'l of a rowboat and beat hell out of it for another decade. . . then quit using the boat 15 yrs ago and left it in the weeds. The scarf joints are still holding. http://www.acehardwaresuperstore.com...52.html?ref=42 Jim |

Reinforcement wouldn't hurt either...either some wood/brass/steel pins/dowels or serve the joint with heavy twine and saturate that with epoxy. And forget the steel filings and JB Weld...either plain epoxy or type 2 yellow glue should work well. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

No,it's just a filler.It actually weakens the bond. If you want to epoxy wood,you need a THIN epoxy like a boat-building epoxy such as West Systems,RAKA,or System Three.The epoxy has to soak into the wood.you use thin epoxy on the wood surfaces,then use wood flour or fumed silica as a thickener,to fill gaps in the joint. You can't clamp too hard or it squeezes out too much epoxy and starves the joint. Now,if you could glue a metal tube over the scarf joint,epoxy would be good. IMO,good wood glues are better than epoxy for this application. Use a waterproof wood glue. Well, the glue failed while using the hoe, so I ground off the glue and tried another glue I had on hand, J-B Weld. I've had the tubes for probably around 3 years. The packaging claims it's the "Worlds finest cold weld" etc. Well, I'm using the hoe a couple of weeks after this and the scarf breaks again!! epoxies take a few weeks to gain full strength. I never had trouble with the scarf on the other hoe. The angle is about the same, around 30 degrees (guesstimating), the length of the scarf being close to 3x the diameter of the handle. Better glue? and a longer scarf, about 4" long. Dan www.systemthree.com; you can download their Epoxy Book,VERY informative about using epoxies and fillers. -- Jim Yanik jyanik at kua.net |

I am wondering reading the thread again if I shouldn't try something else. I like the post above, especially the spline idea, which is easily implemented with a thin bladed saw and a rectangular slug of steel, and some decent glue. A 48+ hour epoxy would probably suffice, but think getting that Titebond III might not be a bad idea. Does Home Depot carry it? A decent sized hardware store?

Yes & yes but Titebond II would be entirely adequate. BTW - in reference to the post to which you replied - Gorilla glue is not resorcinol. You would be better off using a steel dowel rather than a spline. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

Dan I realize you are already into your project and probably already have the scarf joints cut, but aemiejers has it right - it's a lot easier to just buy the correct hoe at a store for men. The hoes that landscapers use are almost a foot longer than the homeowner variety. R |

Dan Email: dmusicant at pacbell dot net Dan- Having lengthened and repaired a number of garden tools over the years (more of a "can it be done / an academic exercise" than a practical solution" ..here are my thoughts & expereinces. Wood glues (Titebonds, woodworkers glue) are better than epoxies in this application. A 3:1 scarf is too steep, something more like 6:1 is better A few #6 SS screws screws will help. Buying a tool with the right length handle makes more sense. I assume you;re wanting like a 60" handle rather than a 48" handle? Buying a replacement handle is a faster, cheaper, easier solution. And at this point it is probably way better way to go than a new long handled hoe. cheers Bob |
