Had an Idear

[DanaM]

Watched a pipefitter straighten some coiled copper tubing the other day. He did it by stretching it the result was a perfectly straight piece of copper tube.

Got me to thinking that maybe this would work on Cane/Boo shafts. You would have to have some way of holding the shaft in the vise and a way to attach a comealong or some other type of pulling device to the other end. I also think you would have to heat the entire shaft, perhaps boiling water?  I tried clamping one end in the vice heating a section between nodes and pulling by hand, it did work minimally. Thought I would toss this out and maybe one of you mechanical wizards would try it

Thoughts/comments welcome.

my grandpa, being a pipefitter and construction worker all his life, invented a way to intertain himself one day. he went a and told all the other fellers what it was. so that day when the new guy came in, he emediatly pretended to cut a board to short and sent the new guy looking for the board stretcher. said john had it. well, new guy gets to john, who tells him that ray took it a few hours ago. so, newbie finds ray, only to find that joe has it. this continues untill the poor guy has gone to every hand out there, and finally back to my grandpa, who very kindly informs him that there is no such device.

buuuuuut, ifin you hang yer sticks up to dry with a large weight on one end, it should help em to dry a little less kinky than they used to be. but i dont know. let us know as yer idea progresses.

Now that is scary when a yooper starts thinking.

Ain't it though
Seriously this should work if just eneough force is applied to stretch the hot cane with out breaking it.

Brother, I think you have re-hatched an idea that we primitive fellers already use in other arrow straightening methods, only you have it in a simpler form. When you hand straighten an arrow shaft, what you are actually doing is stretching the side that the shaft bends toward and trying to compress the side that is bending out. And then you heat it so that it takes the new form that you have streched it into. I think trying to actually strech a shaft by pulling will try to accomplish this same thing through a more simple yet difficutl method, because it is harder to pull a shaft straight than bend a shaft straight. The guy had to do this with copper though because he had no other way of doing it, since the copper would dent in if he did it like an arrow shaft.

I don't see it as scary, I see it as fun! Gotta love that yooper innovative way of thinking.

Hey Dana, my brother in law is from Hammond, IN very close to Chicago. Does that qualify him as a yooper?

[DanaM]

Sorry Matt butt not even close we have names for them folks from down that way but I can't say it or Sarah will spank me

A wood block with a 3/8" hole in it sawed in half will clamp the shaft in the vise, I thing a wire puller in an appropriate size would work for the other end and perhaps a ratcheting come along to provide the pulling power. A steel pipe filled with water for boiling the shafts hmmm anyone know if cane can be boiled or steamed???

[Papa Matt]

What exactly does constitute a yooper then? I thought it was just the accent...

[DanaM]

Nope you have to live in the Upper Peninsula of Michigan, and a true Yooper was here

We call it the UP or Upper Michigan so Upper = Yooper eh

[Papa Matt]

Gotcha

Dana, how 'bout a wooden block with a hole through it pulled along the heated cane to straighten...only problem I see is securing the smaller end.
now I realize that cane is tapered but I'll betcha that you could still squeeze it through as long as the hole is not wayyy too small.     

having just grabbed a piece of straightened cane made me realize that you'd have to flatten the nodes, but the difference in outside diameter from one end to the other is not significant.   

not sure you'd want to boil cane but steaming shouldn't be a problem.

thats funny i work at a veneer plant and my 2nd or 3rd day they got me with the veneer strecher 

[Papa Matt]

I worked at a factory through college, and you know how factory people love to pick on college summer help, they had me looking for a "sky hook".

   Pappy, the Yooper's got time to think. All the rest of them are Pooping in Florida right now.

[sailordad]

board stretcher huh,

well i aint no carpenter, but we used to send the newbies from vo-tech,who thought they knew so much, down to the parts store
for cans of 150lb compression for weak motors. we would call the parts store ahead of time and get them to play along
