repair???

[mikekeswick]

He would also be risking it by just wrapping it
I say go for it but go slowly! Give yourself a few hours and turn off phones etc so you don't get distracted.I actually did this on a friends bow that had been overdrawn and failed next to a pin knot. I managed to get it perfect and apart from the slightly different colour of the 'plug' the gluelines are perfect.It is more of a cabinet makers skill (hence I guess Dean having it on his website) but with patience/finesse/skill it's more than doable. Sharp chisel and a nice fine saw are necessities. Two steel edges also help to handy if you clamp them on the sides for depth gauges/reference whilst making the saw cuts.

Tried it all Eric here.

I used the roll over section of my belt sander to cut the dip for the patch, used the same belt radius to mark a piece of scrap for the plug, pretty easy to do.

Dean Torgus advises to not have a perfect, tight fit of ones plug and leave a small gap for urac in the glue joint.

The plug in the picture held up for three years of heavy shooting then the plug developed a cracked that spread into the limb and ended the bows life. I only used a spring clamps pressure to hold the plug in place while the glue set, pressure from a C clamp might give you a glue starved joint.



If it were me I would super glue, thread wrap repair method, much easier and a very good fix for this kind of problem.

Well i did surgery last nite, forgot to take pics.of the process  tryd a square patch and i finally broke the seal of the can of urac that has been sitting around hope i got the ratio correct.first time with urac and reparing so cross your fingers hope after a 10good hours to leval off the patch. How long before i dare put strain on it?

[PEARL DRUMS]

24 HOURS

[Eric Krewson]

Urac reaches it's maximum strenth in 48 hours.

[George Tsoukalas]

Good. Glad it worked for you. Keep in mind that knots are weak spots in a limb and heavy reflexing is best left for pristine staves. Jawge

Do i wait 48 hrs and try to stress it or grind it out and radius the corners?

[PEARL DRUMS]

I have never waited more than 24 hrs with URAC with any project I used it for. Take it for what its worth.

[soy]

So you ars saying it looks good enough to try

[PEARL DRUMS]

Nope:)   But I am saying I always wait 24 hrs with URAC. I told you my fix idea already pal, Im not switching teams half way through the game!

I hear ya pd.kust a little nervous about this project 

[Sempertiger]

I'm not an expert, but I Have done woodwork where you can't see a seam. From what I've read, and what I've done with gunstocks, it looks like your patch looks a bit small, gaps around it, and It appears to be a different wood.

the issue is that the glue, and different wood take pressure differently than the original wood. you can mitigate this by having an extremely thin, can't see with the naked eye, seam, and, at least with heavy recoil rifles, you always use the same wood. I've seen good stocks explode in the rear grip area when a different kind of wood is spliced in.

Because of that, I would be inclined to give the glue the time it takes to get to it's full strength. However long your particular glue takes.

Sempertiger ...i have heard that to much, and to little of a glue line are noath killers in this app.i think this one is doomed eather way but i agree with you, thanks

[Sempertiger]

it's never doomed till it breaks, imho

And, If it breaks, find something positive with the situation. One of the books i've read says you learn a lot from every bow you make, you learn a lot more from every bow you break.

Also, if you aren't happy with the repair, take your time and cut it out, then redo it. You always have room to repair till it breaks. If it comes out too light, chalk it up to a learning experience, or, do like PD's little experiment. glue a lam of a good compression strong wood to a flatened out belly and, if you desire, glue some kind of working backing, sinew or wood, to the back and retiller to your desired weight.

Thos one is a little wavey /twisty to lam and i an happy with the repair just not the situation ...just a little gun shy
