    removing aluminum anodizing

    Holy Crap Eastwood Anodize remover is $30.00 vs a can of drano for around $7.00 If the Eastwood stuff were $10.00 I'd say okay you're only wasting $3.00, but your wasting $23.00. Drano is lye or sodium hydroxide the exact same chemical we used to strip anodize in a custom anodizing shop...

    removing aluminum anodizing

    Drano is mostly Sodium Hydroxide, this is the same chemical that we used to etch the part, and strip parts, it works great. Here's a little fun experiment for you. Take Drano in glass bottle, add water, add aluminum foil. Keep adding foil. Pretty soon the foil will react with the water...

    removing aluminum anodizing

    Yeah, I worked in anodizing in college. We did mil-spec anodizing, but we were mostly a job shop. Anodizing has good "throwing" power so it tends to build quite evenly. I can't remember exactly how far into a hole anodizing will throw, I think it was 1/2 the diameter but don't quote me...

    removing aluminum anodizing

    You are mostly correct. Bright dip is an chemical polishing process that uses phosphoric and nitric acid heated to between 180 and 220 degrees F. It does not make the coating thicker, but it may make it more durable since the coating is now flatter and more uniform. Bright Dip solution is so...

    removing aluminum anodizing

    Fun facts about anodizing: The anodizing process only works on aluminium. It takes place in a sulfuric acid bath chilled to 70 degrees F. and coverts the surface of aluminium from pure aluminum to aluminum oxide. Hard anodize takes place in a sulfuric bath at 50 degrees F, and uses...

    why is my welding inconsistent?

    That's funny. I'm not disagreeing with you Mad Dart, but I've heard EXACTLY the opposite. The rationale being that by pushing into the weld you have better gas coverage. From my own experience, I've found it easier to see and control the weld puddle by pulling the gun. I've also read on...

    why is my welding inconsistent?

    Couple of things some already said: 1. Clean Clean Clean BOTH SIDES IF POSSIBLE, any contamination will cause problems even if it is on the reverse side. 2. The temperature of the material. Thirty or Forty degrees can have a real impact on the welding. So if the temp of the material...

    Millermatic 200

    Yes, for best results on sheet metal .023 is essential when using a 220 welder. You can buy a 2Lb spool at Home Depot for $11.47 and 2Lbs is quite a bit of welding. The thinner wire puts less heat into the material, considering that you can't slow down the wire feed speed as much on a 220...

    Millermatic 200

    Do your pricing homework regardless of what you buy. For some reason welders hold their value pretty well. Your buddies Miller may not be the smokin' deal you think it is. As for value, for a brand new welder, I think the Miller 211 is an excellent deal at 1040.00 at Cameron welding. This...

    liquid steel

    I don't know, there are some adhesives by 3M designed for non-structural body panel installation. Clearly JB weld is not the appropriate adhesive. You might shoot him this link so that he does it at least "kind of" right...

    Which color Photo shop if possible

    The Dodge in the upper pic, the purple is close to a factory purple used by Mopar back in the day. The lower color isn't anything close to a factory color. So of the two, I'd go purple. I like to stick close to factory colors. But, if you really like Orange but think Hemi Orange is too...

    Help identifying a factory color

    Little background. I own a '67 Dart Slant Six Car that I am putting a 6.1L Hemi into. I am going for a clean "industrial" look, complete with dog dish hubcaps. I've decided on a white, I've even seen the white I want at the Bixby Knolls Dragster Expo and Car Show in Long Beach California...
