heating element spliceing question
Some time back, I managed to scrounge up another Thermalyne heat
treating oven. Cute lil thing, about a 5x5x8 cavity. Checking to see why it wouldnt heat, I found that one leg of the heating element had broken. This particular oven has three sides made of the element embedded in a ceramic, so three sides come out at one time. The leg from the switch broke off flush with the top of the ceramic. I carefuly chipped away at the ceramic until I got about 3/8" of the lead exposed. It needs about a 3" piece of some thing spliced to it, to make the run to the terminal strip. The original was just a long piece of the heating element. Ive tried crimping a wire connector to it, but it seems to not grab very well and pulled loose while reinstalling the unit. I gave it a quick shot with the mig welder using regular welding wire and gas, and it held for a bit, but was still a bit fragile and broke free while installing it. Ive since installed the heating unit, and have a new lead run and overlapping the stub. How do I splice them together? I do have temporary use of a mig with gas, and stainless wire as well as regular. I also have a tiny bit of silver solder, regular brazing rod, etc etc. Any suggestions? Its possible I can excavate a bit more wire for a nut and bold mechanical connection...but would rather not break out any more of the ceramic. Thanks in advance.

They can be tightened up with wrenches to be very secure, and many are made of brass or copper. Don't think soldering will hold up due to the heat involved. Ken |

heating element spliceing question
Kanthal do give details about welding FeAlCr elements like A1. Its best
done with tig and using element wire as filler with the same composition as the element. I would expect anything but the FeAlCr would fail fairly quickly. As I understand it after the first heating the wire does become prone to breaking when handled so bend it as little as possible.

heating element spliceing question
There are a couple of different types of heating element wire. One is
Nichrome and the other is Kanthal. The Kanthal elements are used in pottery kilns and other places. Kanthal can take higher temperatures than Nichrome. The Kanthal is a iron aluminum alloy that depends on the aluminum forming a oxide coating over the wire. So it is hard to splice and also hard to weld or solder. Hard as in pretty much impossible. Nichrome however can be silver soldered. Don't know what you have, but I would try silver solder. If all else fails, you can replace the entire element reasonbly cheaply. Seattle Pottery sells Kanthal elements but maybe not ones for as small a oven ( unless your diamensions are in feet ). IIRC They also sell kanthal wire that is not already coiled. If the element is Nichrome, I might have an element that would work. Dan Gunner wrote in message . .. Some time back, I managed to scrounge up another Thermalyne heat treating oven.

Spot welding is the only way to connect to the wire and it needs to be
completely imbedded back into the ceramic as otherwise it will get too hot and just fry. In addition, the wire is extremely brittle after it has been heated good once so any mechanical motion may break it off again in a new spot. -- Bob May Losing weight is easy!

Then I applied flux and soldered with 45% silver solder and a propane torch. The solder flowed readily and made a nice little bullet shaped blob over the connection. Testing showed that the connection was good and it ran much cooler that the element wire on either side of blob since it's resistance was very low. The element wire got bright red, but the blob was so cool that it did not glow at all. It was 30 years ago and the waffle iron was still working at last report. Randy |

heating element spliceing question
Hi Gunner,
I own about 10 annealing ovens for my glass work. my largest has a 10 ft long ID. So I deal with elements on a regular basis. It's been my experience that any "fix" is a temper one. When elements get old they get real brittle and tend to break real easy. They also get thinner as they age, especially if it has been used at high temps. An elements over all length determines the heat range created with x amount of watts of electricity put to it. As they get older, thinner, or shorter, they will burn hotter and tend to burn off quicker. As mentioned by others, using a bolt to connect will also create a hotspot at the connection. My best advise is to just replace the element. I suggest that you replace the others as well. They can't be in to much different shape. By doing so you'll be good to go for years to come. If not., you may be doing it all over again next week, or next month......or..... If you can't find the replacement you can make your own. Just gauge the wire size, count the number of turns. Use a wood dowel or threaded rod in a drill to wrap it up. You can get nicrom at McMaster's. Or many of the kiln manufactures will wrap them for you. You will just have to stretch them to length to fit your oven. Thanks for the welcome. I found the thread on cutting glass and I'll add my 2 cents worth. I didn't think I would be able to contribute to much in this group, guess I was wrong . Glad to help when I can.

heating element spliceing question
Thanks Shiver,
I've been working glass for more than 30 years. I'm a second generation glass blower, my dad got me started as an artist when I was a kid. My family had a small gift shop in a tourist town in Michigan. It happened to be close to Midland Mi. where Dow Chemicals world head quarters are. I eventually ended up there and worked for Dow as a glassblower for 13 years . At one point Dow had 5 glass shops around the country. The main shop in Midland was designed to house 20 glass blowers. When I started there they had 9 men left on the floor and all the other shops were closed already. We specialized in building what they couldn't buy anywhere else. From lab scale to production and pilot plant scale we did it all. There are 4 men left now for Dow globally. The tool & dye shop is gone along with most of the other skilled trades that used be there. Isn't globalization great! The tool & dye shop was across the street form the glass shop. We always had a great rivalry going on as you can imagine. They were a great bunch of guys and good friends. We had lots of fun with each other, but most of all we had great respect for each others trade. I left Dow in '93 and came to San Diego to start my little business. I guess I was tired of all the disrespect from the corporate cock bights that ran Dow. I didn't trust them with the future of my career anymore. I only had to look around to see what was happing all over Michigan with the auto industry. (which a lot of you guys probably used to work for one way or another) Being that I was single and didn't have a family to worry about I decided to take the risk and went for it. It hasn't been easy, but I'm still here. In the last 11 years I have taken about 10 days off total. Just in case you were thinking that I have it made! In an effort to keep this short and not boring the hell out you all I'll end it here. I didn't want to get to political so early. I hope I didn't offend anyone, especially any of you corporate cock bights, I know how sensitive you can be. Randy H.

Total top down reshuffle, about 3000+ out. The main problem is it's taken 6 months and still isn't over. For myself, I enjoy the work, or used to. I always said I'd stay until they ran me off as long as it was fun. I always thought the end of my career would be they'd run me off, now I'm not so sure. Oh well, the severance package is good and I'd get full retirement. But I'll sure be glad when this bull**** is over one way or another, and I don't care which. I don't intend to go through another round in five years. I always had a lot of respect for Dow glassblowers. In Texas, Rex Epps and I believe a couple of others formed their own outfit when they retired, and have done very well servicing Dow as well as others, so I'd say they're better off on the outside. See http://www.sg-p.com/ And in case anyone's wondering, I'm not retiring in Midland except long enough for my wife to retire. Pete Keillor |

Nope, it's still there. The natives are proud of it. I don't mind it, particularly, although it's hardly the tourist attraction they believe. The area's o.k. in the summer, it's just the other 11 months. Pete Keillor |

heating element spliceing question
Hi Gunner,
Our gift shop was in Frankenmuth for many years. We were at the top of hill between where Bonners used to be and Zenders at the bottom of the hill. We sold out in 1979. My folks moved to California. I stuck around and got into Dow. One thing I miss for sure is the summers in the north lands! Not so much the winters. Take Care, Randy H.

heating element spliceing question
Hi Guys,
I often show people a picture of the tridge that is on my credit union Visa card. Now who else has a three way bridge to nowhere? As I sit here writing this I hear the police chopper over head and sirens in the back ground. I'm literally 15 miles from the Mexican border. My shop is in a gang ridden area of San Diego called Bario Logan.. I like to call my shop "the Alamo" I commonly see the Mexican flag flying across the street accompanied with blasting mariachi musica! My building gets tagged at least twice a week from competing gangs. Every few blocks is a different gang. They like to **** on each others leg by tagging . The Police say the 30th St. gang is the largest in SD. with more than 500 members. My shop is on 29th St. A few years ago on 30th St. a man was walking home from the store with his kid. He was beaten to death in front of his kid by 5 gang members because they wanted $5.00. I have recently purchased 2 hand guns and I'm applying for a CCW. Trust me, .....Midland is not so bad.

Randy H SC Glass Tech Scam Diego, Comi-fornia Geeeezzzz..... I think I'd buy a dumptruck load of guns and ammo, dumped out on the street, and then leave.... the problem will take care of itself... Then you could go back after all the shooting is over and take care of the one guy left... G Ken. |

Randy H SC Glass Tech Scam Diego, Comi-fornia Dang, Randy! Get the hell out of there while you can. I know the move would be disruptive, but from the looks of your work (very nice!), your customers will find you. I bet you could find somewhere more central to your clientele, anyway, although finding it at a reasonable price wouldn't be as easy. As far as Midland goes, it's fine except for living in Dowland with some of the ridiculously stuck up (ABOUT WHAT?!) third generation employees. It's just not home. I knew when we moved up here we'd miss family (over 600 showed up at the last reunion) and salt water. As a matter of fact, we're taking the boat back to Texas and leaving it there. We'll ride the company shuttle down (no cost, X trips a year allowable) to fish and visit. Good luck with your location. I hope those macho fools don't decide you have a lot of money or tools before you decide to git. Pete Keillor |

Gunner wrote: Some time back, I managed to scrounge up another Thermalyne heat treating oven. Cute lil thing, about a 5x5x8 cavity. Checking to see why it wouldnt heat, I found that one leg of the heating element had broken. This particular oven has three sides made of the element embedded in a ceramic, so three sides come out at one time. The leg from the switch broke off flush with the top of the ceramic. I carefuly chipped away at the ceramic until I got about 3/8" of the lead exposed. It needs about a 3" piece of some thing spliced to it, to make the run to the terminal strip. The original was just a long piece of the heating element. Ive tried crimping a wire connector to it, but it seems to not grab very well and pulled loose while reinstalling the unit. I gave it a quick shot with the mig welder using regular welding wire and gas, and it held for a bit, but was still a bit fragile and broke free while installing it. Ive since installed the heating unit, and have a new lead run and overlapping the stub. How do I splice them together? I do have temporary use of a mig with gas, and stainless wire as well as regular. I also have a tiny bit of silver solder, regular brazing rod, etc etc. Any suggestions? Its possible I can excavate a bit more wire for a nut and bold mechanical connection...but would rather not break out any more of the ceramic. Thanks in advance.

The big question is can it make contact with metal. I bet the thermal expansion problem is a problem. A new one isn't that expensive - but if one has a TIG or MIG - give it a try if you are into it - and let us know.
