I am not a bamboo guy
So I ask why would a tip when bent stay - And if bent the other way Stay again

Bill - willierods.com

Bamboo rods will take a set (hold a bend) if their fibers have been overstressed.
But unless the damage is severe that set can be straightened out by applying heat and bending.
This is best done by someone who has experience but it can certainly be learned.

new tips Said to be heat treated

Could it be Moisture ?? I was told to straighten - heat and then a good coat of varnish ????
At least about a foot down from the tip

Bill,
Each bend is different. Take it slow.
I saw a video of it being done.
He held the blank over a torch for a few seconds and applied pressure.
Then kept repeating it carefully.

I had a bamboo spinning rod which had a set.
I heated the rod by holding it over a pot of boiling water while gently pressing the bend out.
I did this a few times and it came out very nice.

This is Not A Set -

I have two -- NEW -- tips that i was playing with and as I pushed them onto the floor

I noticed they were keeping the set Or bend

I then turned them 180 and did it again - They keep the bend again Turned then several times on every plain they keep a bend when flexed
It was AS IF I could bend them any way I wanted and there would be a bend in the tip About 8 - 10 inches from the tip

I KNOW THIS IS NOT GRAPHITE BUT gee No Memory I was told moisture Heat and then varnish ????

No one has ever had this -- Bad glue -- sections moving

IF NO ONE HERE KNOWS SEND ME WHERE I CAN FIND OUT ---- I WANT TO KNOW WHY
Thank you

Bill:

I would say something is not right with the blank. I have seen Bamboo take a set after being leaned up against a wall overnight, but don't think I have ever seen one take a set in the manner you discribe. Angler's Roost might be the place for you to ask this question. Bamboo is a strange critter, and takes someone that knows Bamboo to figure out what it will do.

Bill,
There are some good bamboo rod forums on the web.
I think you'll get a lot better info there than I can provide.

I recommend this one:

Good luck.

Here's a video showing how to take out twists and bends from Bamboo rods.

If this doesn't fix the problem then I don't know what to suggest.

What you likely have is bamboo that was not properly dried before it was glued together. Bamboo retains moisture and if it is not dried/cured before assembly it can act exactly as you describe. Personally I don't know of any way to correct the problem. I've straightened plenty of crooked bamboo sections using a heat gun & rolling the sections on a flat surface but have had no success when the "boo hadn't been dried prior to assembly. The video David posted is a good way to take care of twists and bends

Ken

I was told it could be moisture
If moist or uncured glue - seems to be in 8 - 10" of the tip Maybe junk
I am going to try heat several times and keep my fingers crossed

ken - you sell blanks ??

Yes - I do make bamboo from scratch (or better 'from plane'). If the bamboo was glued up "green" the moisture will be sealed in by the glue that the canes were glued up with. The outside (visible side) should be the enamel from the outside layer of the bamboo culm. Good luck with the heating - let everyone know if you have success with it.

So you sound like if it was green -- any heating will do no good
I am heating them now and will do them several times
Then a coat or three of varnish

Just curious, where did you get the blank?

I just don't want to say

Ok.
If I got a defective product, I would send it back to whoever sold it to me.
There are some inexpensive blanks out there and these problems you are having are not uncommon.
Most likely not a moisture problem, but instead a poor manufacturing process.
Good luck.

"Specializing in bamboo, but will do other materials too!"

Old school bamboo rods were built with opposing guides (one on one side one on the opposite) for the purpose of taking the "set" out during and after use , by simply flipping the section over and using it . If I come across a "set" rod I steam it and apply pressure till the "set" come straight , torching can become dangerous as the heat can destroy old resin or glue , leaving the rod usless . Larry

heated the tips with a hair dryer several times
Clear with two coats Let dry
Seems to be alright -- Maybe it was just a little moisture
