Adding weight to steel BH inserts-Build along

[heydeerman]

I shoot carbon arras and I like to hunt with 250 grain heads. I have a mess of 100 grain inserts and when I match em up with 125 grain heads I come up 25 or so grains short. I noticed today that the 100 grain inserts have a drilled out hole in them and a 16 penny nail fits real nice in that hole.

Here's what I did...

First off you need next to nothing to do this. Vice grips, hacksaw and a file will get it done. If you have a bench vice and bench grinder it will make it easier. If you have a scale that weighs in grains you can get pretty precise. If not I'll show you how to get real close to 125 grains in a minute. That's all you need for tools. For supplies you need a few 16 penny nails, a sharpie to mark em, and some kinda glue.

   

First thing, cut the tip off the nail. This will allow you to put the nail into the insert.

 

I was not sure where to start so I put the nail all the way into the insert and marked it.

 

I cut it there and weighed it. It was pretty close. I hit it with the grinder and weighed it till it was where I wanted it.

 


To put it together I used Gorilla Glue. I really like the Loc Tite Sumo glue too. After thinking about it JB Weld would proly work best.

 


I put a little on something I am throwing away and tear off the cotton on one end of a cu-tip.

 

Use this to put glue in the insert where you are adding the steel. You will have to push the steel into the insert a coouple times to get any air out. It is a tight fit.

I then took an old box, cut some small slits in it and used it as my drying rack.

 

Here is what I come up with.

Depending on the head you are wanting to use if you wanted a little more weight you can add some if needed. On this Woodsman I can cut the nail longer

 

This will take it all the way to the top of the taper in the head. This gave me a 270 grain head when finished.

 

Here is the finished product.

I usually use JB Weld. That's why I was thinkin I shoulda used it to glue the steel into the insert. I used super glu on one and they all should hold. As an after thought if I had to change anything Gorilla Glue or the like is heat reversable and will hold up for hunting.

hmmmm jb weld you say..... i didnt know that could be used. i was thinkin you would use a 24 epoxy. is jb weld a common thing to use for gluing bh to adapters??

i only ask because im thinkin about usin 160 snuffers to a 100 grain adapter. and if i didnt read this post i would have got some epoxy for the job.

JB Weld is good stuff, I use it to glue 100gr brass insets into carbons...PR

I do something close to the same but use lead solder instead.  I cut the solder to a length that gives me the weight I want to add.  Then add a little flux into the end of the insert and stick it into a plank then drop in the solder.  

Just hit it with the propane torch until the solder melts and tada!! You're finished.

have to thank you Jim.    for reasons I wont go into here, I had to get a replacement bow.   my arrows tuned to my old bow  (with 200 grain points) haven't been shooting well with the new one.   after spending yesterday bareshafting til i was sore, I rememebered that I had 250 grain field points in my tackle box....pulled them out, screwed them in and viola....4 arrows touching in the dot at 20 yards.  

then the panic sets in....the season in connecticut starts tomorrow, my first day hunting will be saturday....and unless I express ship for $20 a dozen 125 grain broadhead adaptors worth 7 bucks.... I wont have matching weight WWs to shoot on saturday

then (and here's where the thank you comes in)....I remembered this thread.   I have 75 grain adaptors, shorter, so they have a bigger hole.  had to go with 20d commons instead of 16ds   but they fit perfect.   they are glued up right now and I'll have to do a bit of fine tuning (read: grinding) to get the weight perfect...but I think they'll work just fine.  will let you know how it goes!
