Im interested in building a heat treatment oven for Aluminum. Can
anybody give me some insight?

What do you want to do? Solution and age? Anneal? What grade(s) of
aluminum. What sized parts?

thank you for responding. I would like to straiten Al "shafts" used in
underwater spear fishing. The impact with the fish often causes the
shaft to bend. I beleive the avenue I wish to follow is annealing. As
far as grades I can not say because they vary. I have always wanted to
build one of these; Maybe designed to accomodate other types of metals
as well. Any suggestions or concerns? thank you. -Davey

thanks Lane. I have not googled ol posts but I will. Im new this but I
hope I can navigate though and find it. Thank you so much. God Bless
You and yours.

Aluminum shafts for spear guns....never seen em. All I have ever seen
were some el cheapo galvanized steel and the better ones were always
stainless......I seriously doubt the impact of a spear hitting the
fish is the problem if your bending spear shafts. Your tip is what is
doing it. Are you using a fixed in place on the shaft tip or a slip
tip. When you use a fix tip, and do not make a clean kill and work
your way to the fish and grab the shaft, thats when it gets bent. A
slip tip will penetrate through, and still be connected with a steel
cable to the shaft forming a flexible portion, so bending of the shaft
is not possible. I have speared some Greater Amerjacks in the 60 to 80
pound class with slip tips and a 5/16" shaft and never bent one as
long as I used a slip tip. Before that I used to bend up a heap of
shafts on every dive, when I used fixed tips.

Would the equipment they use to re straighten arrows work ? Pretty
common for archery , if so you might ask at a specialty store locally or
search on line . Luck

Thank you for your reply; your information is quite helpful. I am not a
spear fisherman. The man who asked me to straiten his and other mens
shafts is however. Im a welder. lol All I im actually interested in at
this point is the correct information to straiten them out, For
whatever reason they have been bent, they are bent and i would like to
build an oven. I certainly am going to pass that info on to them. Do
you have any advise for this fun project ahead of me? I would also like
to use the oven for Ferrous materials as well. How feesable is that?

Thanks Ken! That seems a great idea to follow up on. I will do that.

An arrow straightener is nothing more than two v blocks, a lever in
the center to apply force, and a dial indicator.

You can make a decent one in a couple hours start to finish.

A Drill Collar straightener is the same thing, only on a larger scale.

(Drill collars - 31 feet of SS, 4 to 8 inches in diameter, used by
drilling outfits for something. I just made 'em.)

Collars were used to hold the drill bit from wandering so they can hit a
targeted location . Been a long time for me but I doubt it has changed .
Darned things were some heavy I remember that .

Clunk, the penny drops "Oh,yeah, now I see..."

Thanks. Like I said, I just made em for three months, never really
thought about it further.

Kind of like the story of the salesman who came into a shop, asked to
she the guy in charge, and while waiting, asked "so what do you make here?"
and when told "we make gears" he said "I thought you just bought them."

(Here's your sign.)

Hi Ken. Do you think a drill collar would work in straitening out these
shafts? Im still very interested in the oven though. If you have any
more info Id love to hear it. Thanks so much!

Drill collars are extra extra heavy pipe intended to add weight to
the drill string, and add some stiffness so it doesnt wander. Its
also used as something of a safety device in exceptionally high gas
fields. It helps keep the drill string in the ground if you hit a gas
pocket, rather than squirting 10,000 feet of heavy steel pipe out the
top of the derrick and winding it around the country side (not a
pretty sight and will make you both **** and **** your pants while
running like a somebitch away as fast as you can)

A "whipstock" is what is used to direct the drill string off to the
side. Under some homes for example, where you cant drill straight
down.

Or under the neigboring country to steal their oil
