Post your Jig failures

This is a fletching jig that did not turn out to good.

I've had plenty, but they all end up in the wood stove.

Don't have a pic...but I will say using a single 2x4 didn't work as a base for a bow jig/form.

Is the bow jig/form a failure or the 2X4 ..?   If its the  2X4 that does not constitute a jig.  Sounds more like a caul.  Then again exactly what is the definition of a jig.

Well..I guess you're right....lol A bow "form?" made with a 2x4 base with short pieces of wood sticking up from it to clamp wood slats to isn't a jig.
To answer your question....the 2x4 base wasn't rigid enough nor stable enough as it warped a bit over time.
From Wiki...."A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. A jig is often confused with a fixture; a fixture holds the work in a fixed location. A device that does both functions (holding the work and guiding a tool) is called a jig"
A caul is strip or block of wood used to distribute or direct clamping force....though I've heard many bowyers calling a piece of curved wood used to clamp/steam in recurve tips a caul.
Maybe a bow "form" is a gluing fixture?

I learnt me sumfin t'day!  Though I'm still a little confused.

I played that game a little:)

I don't know if this classifies as a jig failure...  Probably my biggest failure in bow making...

   This is what happens when you have the top form too close to the bottom form...  Everything goes sideways...

   I was trying to put a little extra pressure on the ramps to get my lams to sit down so when I shaped the top part of the form I only gave about a half inch of spacing in the riser area...  It was a Catastrophe...
