Welp, school finally started up down here, and i got into the welding program at a local vocational school. Anyway, were doing o/a welding first off, and im pretty happy with my work.







Well, other than this... Were working on lap joints right now, using filler metal. Every time i try to pull this off, i end up melting the top plate apart. Ive tried different sized flames, different angles, etc, but i just cant get it right.

Any advice guys?? Thanks :drinkup:

Been a while since I welded(about 5 months) and I am horrible at welding thin metal so I decided to practice.


Laying out the "feet" as I called it before I started to work on it, but it looks more like a tail. Check out that sweet break action on the actual holder.


All welded up, and ready for sandblasting


All done!

The nominal OD is 0.405". These are 304/304L stainless so they may not bend easily.

My Imperial bender does tubing but the pipe is too large. Already checked and they don't make pipe dies. I also doubt the bender would survive long doing pipe anyway.

Does anyone know of a bender that can do small pipe?

I thought about threading some 3/8" tubing but the nominal OD for for 1/4" pipe is larger :mad:

This may turn into a build your own project but I'm in a rush to get this job done so if I can find an off the shelf solution that would be better.

Any thoughts would be appreciated. ]]> forhire http://www.weldingweb.com/showthread.php?t=44491 Question for Jim Colt http://www.weldingweb.com/showthread.php?t=44490&goto=newpost Thu, 02 Sep 2010 21:28:59 GMT Are the cut charts the same for the pac 182 and 186 ?

I am a photographer and studio owner and have always built my props and sets using wood, and often wished I could weld, I love to build things and never could with metal.

I purchased a Lincoln Pro Mig 140 to play around with and see if I can do this, always been able to learn anything I put my mind too, so hoping this also is possible.

The only instruction I have had so far is a Covel DVD and youtube, and have learned to look for penetration in the weld to see if its good.

I have a hard time seeing where the puddle is when welding, I am using a auto dim helmet and its set to 9, the lowest power I think. Is there a trick to seeing the seam your welding, or is this something you just get a feel for as you learn.

Also, as far as testing a weld. If I weld something and can not hammer it apart, is is safe to assume it will hold. I realize it will not look great, but talking about strength?

I will post some pics later and ask for some help on how to improve, with my business schedule not sure when I can take a welding class. ]]> General Welding Questions Denny Kyser http://www.weldingweb.com/showthread.php?t=44488 Help ID bolt manufacturer http://www.weldingweb.com/showthread.php?t=44487&goto=newpost Thu, 02 Sep 2010 20:02:41 GMT I have been trying to identify the company who makes fasteners with the mark "THE" on the head.

It's connection to a 30Amp, 120 Volt circuit with 10 gauge wire. Test metal is about 1/8" thick maybe a little less.



Setting above:
C6 , E2 , E3
F4, C5
E+5, D5
E+3 , E+4

(E+) is 1/2 way between E and F.


E+3, E+4
E+5, D5
F4, C5
C6, E2, E3

Open Circuit Voltage Settings:

A 11.6v
B 14.4v
C 16v
D 18v
E 20.3v
F 22.6v
G 24.6v
H 26.5v

I think the burn through is partially due to too much of a gap in the test pieces - I'll fix that in the future.

I'm guessing that I should try to keep the voltage setting around E or F and mess around with the wire speed, keeping on my line and staying at the leading edge of the puddle. Does this sound correct?

As far as the correct amt of heat goes, am I looking to see a tiny bead on the back side?

I'm open to any additional advice to help me get to a point where the welds are half way decent. ]]> MIG, TIG, Stick, And Oxy/Fuel Welding ekim http://www.weldingweb.com/showthread.php?t=44486 Lengthening Input Shaft on Transmission http://www.weldingweb.com/showthread.php?t=44485&goto=newpost Thu, 02 Sep 2010 16:44:32 GMT Hello All:
Need help here from the pro's. I need to lengthen the input shaft on my 4spd manual transmission by about 3 inches. Plan is to have a professional weldor insert a piece of 1-1/8 diameter 4140 to accomplish this. I am unable to heat treat the finished item so that is why I chose 4140. Is it reasonable to have this attempted, I will provide a means of centering all three pieces but am not competent to do the welding. Would TIG be a good choice and any ballpark guesses at cost? Thanks to all for reading this and hoping to hear back. Take care.

Leaky water pump. See the pulley is sloped down a bit,

Attachment 55177
The best part of a day later, the pump is off the Leyland. Working off a step ladder and reaching over to the motor is fun

Attachment 55178
The front bearing was jiggered, the rear bearing was totally collapsed and stuck three inches in.

Attachment 55179
I soaked it with penetrant and heated it and tried drifting it out. Unfortunately I had the drift against the edge and a piece broke off. The inner diameter of the race was the same as the bore of the pump body, so I couldn't get anything to press it out.

Next post please.
