Title: Heat strips
Post by: Bow man on February 25, 2019, 06:42:59 AM
Looking for a source for heat strips for cooking a bow.  We have some now but wanting some spares. The source we got them from before is gone

Ive used heat silicone heat strips and still have some. The only way to go is the stainless steel strips with a battery charger. Its bullet proof and only takes a little learning curve. Total set up should be $300.00 or less. Love mine. Frank Novak.

I got mine from KEENOVO on eBay.  The price was $67.50 for each strip.  When I found out they were shipping from China, I tried to cancel the order because I assumed that I wouldn't get them in time.  I explained it to the vendor and he shipped them and I got them in just 2 or 3 days for free.  No complaints about the quality.

Any luck on procuring your heat strips?

Yes thank you got them coming from Keenovo  like you suggested.  Wish I could have gotten them made in the USA, but they were more than double the price.

And probably double better. Buy USA

Frank could you give us a detailed plan for the heat strips and battery charger method.

Jess, Ill take some pics along with some dialog . Ill try to do that today. Ill tell you, once your set up and with a little learning curb and I mean little, you have a system that is safe, easy and almost bullet proof. It sounds intimidating at first but is sooo easy and works great. Frank.

The ones I found made in the USA did not have good reviews

How many of the heat strips do you need for the average bow curring box Im also interested in these ? In conjuction with my PID controler when I get it built !

I believe the heat strips are placed on the form both above and below the bow so there is no need for a box at all. I was very intrigued by the idea until I found out I can get my hot box in excess of 200° so I can use it cure my stabilizing resin and not risk marital floggings for mucking up the oven.

I still use a hot box. But all I have read about the heat strips is durability is no good at best. And that you are way better off with the the charger system in the long run.

Thanks Lonnie I was thinking of using a single strip in a hot box if I could get it to 175 F max ?

If they dont last then its not worth it I will stick with the ceramic IR emitters glad you said that I was thinking they where durable but the emitters are cheap to replace !

We have had the same set for 4 years now with no issue.  They are the Keenovo.  The ones form the US company reviews all said they did not last long.  We use them with a Percentage controller

Thanks Dave let me ask you this do you think 1 strip is capable of maintaing 170 f in a standard hot box ?

Do these have to be used in a hotbox?

I was basing my opinion of them going on the form form a video I saw of the making of a Fred Bear recurve. Of course they had a huge machine and the leads, to what I assumed was heating elements, were huge.

If I ain't supposed to link to that let me know and I'll nix it.

Not sure how that would work.  we put them right in the form with a layer of insulating material between then and the bow. We put one on top and one on bottom

That is pretty wild looking and way more complex than my brain can caculate (kak-uh-late). I would really like to find a PID setup that I can program three different temps at 2 hour intervals. For those who missed it, that is a shameless plug for the brain trust to guide me  :goldtooth: :saywhat: :goldtooth:

I don't know but the guy shur did pull his hands away in a hurry when the press came down, hate to do that all day, hope he has good health insurance with Bear.

The only use I've been aware of for the heat strips is in lieu of a heat box; they go on the press itself between the aluminum pressure strip and the formica.  This method makes more sense to me than the heat box; direct, even heat across the bow's surface.  I got a heat controller that was kind of a pain to wire up, but the strips work great, even though I've had a couple of bonehead moments.  I sliced into one of them on accident, and once the thermocouple slipped out cooking a bow at 330 degrees for about an hour until I caught it.  Everything was fine except the bow.  These seem to be the same quality as the ones I bought from Mike Fedora years ago.  Lost those in a house fire.  They weren't on at the time, btw.

Same setup I am using,, T/D limbs done in a hour. depending on your ambient temperature of your work zone you will have to adjust current. I use 2 ktype thermocouples on my form to measure surface temps of the limbs.
