Thanks for your suggestions. I've decided to try to find the correct sprocket.

As for the jokes, my id "ironchef" is a combination of a welding and a culinary degree.
I'm also known as ironchef de biciclet to include my cycling hobby.

I made a mistake and got the wrong size sprocket for an electric bike I'm making. The sprocket is a double D but I need a single D. It is also a slightly larger bore. I was thinking I could fill the bore with TIG then bore it to the correct size and then fill it again with TIG and file down to fit t...

I have checked the relay closest to the fan and it operates. The drive roller does not turn so I will see if the torch switch is ok. There does not seem to be any welding current when I push the switch. thanks your your help. I will check some more in the AM. It's been freaken hot and humid the last...

I was surprised the other day when my mug welder did not feed the wire. Where would be a good place to look in a safe manor ?

Would this work on a AC evaporator? What are the pitfalls? Would it work better if the tungsten was balled at the end so the has is bigger?

I need to buy either a 14 or 5 pin connector for a Miller pedal. I have the Amphenol number and found one resource that I promptly lost. It cost around $15.
Any suggestions would be a big help.

Tell me again where to get a 5 pin connector female to go on welder.

My foot petal has a 5 pin connector and my tig has a 14 pin connector. Where do I buy a 5 pin female to go on the tig? What is a reasonable price for this?

I just blew my cover with "et al" meaning "and others" used in scientific reports. Science is my background and in the case of Culinary and now Welding responsible for my endless questions in school that can piss off the teacher. The one more thing is that I will be getting my We...

I had to laugh too! Thanks for your input. I've decided to go with the 1G on the free retest. The money has already been spent so go with it. I'll chalk it of to the school of hard knocks. By the way you should have seen the guys that did two one inch plates! The looked like they were run hard and p...

Sad to say I did not past the certification test. I thank everyone for their input. I'll be doing a retest next Tuesday. I'm considering going to the 1g flat position just to get certified. My original plan was to be certified in TIG but I and others in my certification class at Wake Tech CC in Rale...

Thanks Steve I'll try that. Hope I made it clear that the root pass is not tying in two sides of the groove and the backing bar.

Big problem on cert test for 3/8 v groove with 1/4 " backing bar in 2g horizontal position. Using 3/32 7018 on a Lincoln weld flex on #1 soft arc and 85-95a. Problem is the slag is either floating on the top of the weld or bottom depending on the angle. The root is not tying into the top and bo...
