Corby bolt helpers

[PEU]

I use corby bolts, a lot.
There is one thing that bugged me a lot, once you have both sides drilled and need to finish the front part, putting two corbys to align both sides and then taking them out was a permanent waste of time, so today I thought about the problem, found a solution and implemented it.

Took two female corby ends, drilled it thru and with an all thread and a nut on the other side made a couple of helpers. A lathe would do this job nicer and replace the need to drill the corbys, but I don't have one, so I had to be ingenious

They could be nicer, but I am in the middle of a large batch, so I needed them fast, maybe I do nicer ones in the future (of course we all know this is highly improbable LOL)

Hey Pablo - that is such a great idea!!!! Just recently (yesterday and today) I faced the exact same issue .... and I had to do something really weird like taping the handle to a narrow board to hold it above the work rest (and thus not "wobbling" on the corbys) while I shaped and sanded the front. I will HAVE to remember this idea. Thank you!

Go for the industrial look...........Loveless bolts.

I always use blind aligment pins.
That does the same job
Edit: cool tools you made

Before the corbys I used Loveless bolts, but I like corby much more.

Are blue lines the reference for you 45s or the line you will round the scales to?

Yes, they are SOOOO much better than using a pair of screwdrivers.

I'll try and find them in the boxes of stuff moving into the new shop, but I did the same using two cut off female bolts and threaded them onto 6-32 and 8-32 thread knurled top thumb-wheel knobs. The smaller thumb screws may be simpler than your larger handles as far as not getting in the way.

I have also used these for temporary assembly to fit a handle to the tang for grinding when the handle will have to be removed before final assembly.

Nope, its a defect in the paper micarta, two black sheets instead of the alternating green and black

cool idea ...you could use "Shoulder bolts instead they have some that are 10-24 with about a 1/4 head on them.
you buy whatever shoulder length you want.. the head could be turned down pretty easy using a cordless drill and grinder.
with a lathe you could just turn down some hex stock to make it all 1 piece..
with smaller fasteners you could even pre profile the handle before gluing it on..
again good idea , just sharing possible ways to make it easy to do maybe giving better options like shaping while not glued on while you are at it..

I couldn't find them so I made a new set. I drilled out the slotted end of the male Corby bolts just shy of the threaded stud. I tap the hole #8-32 with a bottom tap.
The female Corbys I drill through from the threaded hole end with a #29 drill and tap all the way through. I cut the 8-32 thumb studs off leaving about .3" of thread. A drop of lock-tite will keep them from unscrewing.
