I'm about to glue up my first ever batch of broadheads and decided to use JB Weld. My concern is extra JB being squeezed out when attaching the broadhead on the adapter and permantly bonding it to my brass insert. Any experience/advice would be good.
Just wipe off all the excess as you go along and you'll be fine.
I also just wipe it off.I also keep the cardboard that I mix the glue on to monitor how it is setting.When it feels firm,that is a good time to unscrew the broadhead slightly to make sure it isn't locked down.Tighten it back down and let it cure overnight.If you are really worried about it,apply paste wax to your insert before putting everything together.
same as above, when pretty firm, i also un screw it just enough to be sure it hasnt bonded, just put the jb weld on the upper 1/2 of the insert, when ya put the broad head on it, will spread it the length without alot of excess, as usual just kinda twist it on as you are pushing the head on to evenly spread the adhesive.. ..
.... and how much, Fellas? Use a brush to make a thin film or a couple drops toward the end? Thanks.
I just roll the adapter in the epoxy. You need enough to ensure you're filling the spaces in the ferrule. If you get lots of excess, just scrape it off with a toothpick or something similar and add it back to the mix.
Better to have too much than not enough.
Some denatured alcohol on a rag really helps to clean it off any surfaces before it cures.
OH, and how long till "firm" enough to unscrew?
That's all great info. I feel better and thank you. I'm always MR. Nervous Nelly the first time I do anything.
To start,make sure all surfaces are clean.I like to sand the insert and roll a small piece of sandpaper and twist that inside the broadhead ferrule.It doesn't hurt to also clean surfaces with acetone or alcohol.
Keep the leftover mixed epoxy and when it is hard enough that it can't shift,unscrew your broadhead and retighten.It just has to be firm enough that when you unscrew,it won't move the bond between broadhead and adapter.You are just checking to make sure it will unscrew.I can't remember set times on JB but probably 3 hrs or more.Check your mixing pad.You will have quite a long window where you can still unscrew the broadhead,even if a little epoxy has drifted between insert and adapter.Once you break that seal,it will stay that way.
Again,if you are worried about it,wax the insert.You will have no sticking problems.
Something you might want to try...
I have been gluing my broadheads into the adaptor/insert when it is off the arrow and before I glue the insert. Once the adaptor and broadhead are epoxied together and set THEN I screw the broadhead into the insert and glue the insert/broadhead into the shaft. I then spin the who shebang before the epoxy setsto make sure the run-out is eliminated.
I have found that generally broadhead ferrules and glue on adaptors run very true and can almost always be glued together nearly perfect. My experience tends to suggest the runout comes from the cut on the end of the shaft and from variations in shaft inner diameter.
Purely anecdotal but you might want to give it a shot!
I took just about everyones advice and got the job done. Great advice guys. It was just too easy and I appreciate it. Used wax and rolled the adapter. As Kentucky Jeff said, all lined up real nice the first time. Shot'em this morning. Dropped the brace height almost to zero twist and brought'em right in. Thanks guys. Season opens here saturday. Will be my first day in the woods with the trad gear. Let's hope for good things!
I have some mineral spirits on had to clean my fingers after I wipe off excess....I wipe with my index finger and roll it away so I'm picking up more glue and not spreading it out.....if I need to, I them do the same with my middle finger...I then wipe my fingers on a pre soaked rag and glue the next one.
Also, if it got into the seem of the insert/adapter....I run my thumbnail around the seem to clean out the glue....no worries.
Terry, I did get some into the seem, but the little hint from JimB to pre-wax the insert worked just great. I actually used some string wax. It's amazing how much I have learned in the 6 months I've belonged here. I appreciate everyones help. I even found my sweet spot with the broadheads in less than 10 min thanks to threads here. Deer is going down Sat mornin! IT'S ON!
