Hey stevo, POR 15 is usually applied with a brush in thin coats but I have used it in heavier brushed applications on horizontally positioned materials. It gives a great finish in thin or thicker applications due to its leveling characteristics but it will run if applied too thick on vertical applications. It can be sprayed but a good respirator rated for POR 15 and sealed eye protection are a must. POR 15 can and will cause brain damage with enough exposure so good ventilation is needed in both sprayed and brushed applications.

Hey stevo, Your 2 cents are worth a lot. The main reason I recommend stick welding over MIG to those starting out to weld is price and individual ability. Stick welding is easily learned and takes only a few hours to start making good welds. I also know many general purpose stick welders that use only 1/8” and 3/32” 6011 rods but that is not so bad when you consider that almost all their welding is on mild steel and/or old steel with rusting/residual paint/oil, in all kinds of wind and weather. Hard to use MIG in wind above 5 mph on rusted damp steel. You are very right about the moisture build up in the flux coating on rods or more accurately the hydrogen in the water that contribute to weak brittle welds prone to cracking). I usually buy my rods in vacuum sealed 5-lbs packages rather than keep a rod oven running. This way I just open a new package when I’m ready to weld something critical. Depending on the welding environment humidity level you have 4-8 hours to use the rods before the flux on them absorbs enough water/hydrogen to have much effect. Stick welding is dirty, cheap, and effective. Stick welding’s main weakness is that on material below 1/8th inch thick, most have a hard time welding with stick. Another reason I have used stick on my builds is to show new builders, for whom money is usually short, that they don’t have to have a 2,500.oo MIG before they can start to weld on their builds. I want them to see that they can achieve satisfactory welds with even a used 150-200.oo stick welder. Not disrespecting the MIG. I have a very nice Miller 252 with all the bells and whistles that I use a lot, mostly on 1/4 inch or less material, but I have welded ½ inch thick and more with it. It is a dream to run on 3/16” and less sheet metal, leaving no slag or inclusions. Metal has to be well prepared and a final cleaning with acetone for best welds. I agree that MIG is theoretically superior but only when done by a knowledgeable and well-practiced welder. vertigo

Hello Everyone, When I think of the Tumbler I consider it in many ways but mostly from the mechanical and sculptural perspectives. While searching for Tumbler information on line I found a really good article in Sculpture Magazine: January 1998 Vol. 17 No.1 titled: 25 Years: The Evolution of Sculpture Tools by John de Marchi 1. The Evolution of Sculpture Tools - Sculpture.org www.sculpture.org/documents/scmag98/sm-tools.shtml o Cached o Similar ... tools and methods for sculpture can have a dramatic effect on the way artists ... proficient with hand tools, and the decline in the average quality of such tools. This overview article covers 25-years of technology, tools, materials, and process advances that are relevant to all sculptural media including metal and fiberglass. (1) The technology revolution, in particular, computers and micro-electronics; (2) The decline in the use of hand tools and conversely, a greater reliance on power tools; (3) Access to a tremendous range of materials and processes; and (4) The issue and practice of safety, both personal and industrial.

Hello Everyone, Have been working on making a welding alignment jig to accurately positioning the front axle assemblies for welding. Also studying fiberglass and other composite materials. Found a good overview of composites from CalTech. Here is an excellent 14-page composites overview paper that might be of use to anyone planning to or actually building a Bat Vehicle that involves fiberglass or other composites by Tim Palucka and Bernadette Bensaude-Vincent from CalTech History of composites – overview 1st generation (1940s): Glass Fiber Reinforced Composites 2nd generation (1960s): High Performance Composites in the post-Sputnik era 3rd generation (1970s & 1980s): The Search for New Markets and the Synergy of Properties 4th generation (1990s): Hybrid Materials, Nanocomposites and Biomimetic Strategies Summary: The Impact of Composites on Materials Research authors.library.caltech.edu/.../materials/.../composites/Composites_Overview. htmCachedSimilar

Hello Everyone, Stripped down the Dana 60 axle ends and next plan to clean and measure critical parts for wear and replace the wheel bearings. Is anyone out there? Hardly ever hear from anyone saying anything good or bad on this site.

I think everything is good so far. It's nice to see different methods for building. I think you have a good process going. Its kind of like jumping off the deep end. Some one's got too and your just watching to see what happens. I think it might help a little more if the pics were imbedded next to the text to make it a little easier to scan the build for reference vs the attachments that need to be logged in and clicked on where it launches a separate page without the accompanying text (I'm a lurker so I'm not always able to login and see progress until I get home.) Just my 2 cents. Keep going people are definitely watching. I'm actually waiting to see how the tires and rims work out. I have checked with various vendors and No One makes Custom Dually Rims in that extreme Size. All the responses I have seen are to use custom adapters or make your own Rims. I can't fathom making a rim...So not sure what I will do...

Hey stevo, Thanks for the kind words. For much of the past 2-years I have searched for solutions to many Tumbler building problems and studied the work of many. Without being able to study the work of the true master Tumbler builders I was forced to work on solving most of the design and construction problems on my own. I've had a lot of AhHa, light bulb flashing on, moments of insight. Problems of design and construction that seemed very difficult revealed themselves to me after many hours of pondering and experimenting. Right or wrong I pretty much had reached a workable solution to most Tumbler building problems before I had earned my full forum membership. Only in the past few months did I reach forum member status and earn the right of access to the building logs of the true Tumbler and other Bat Vehicle master builders like Big Wave Dave. For me the builds of others have become inspirational and an opportunity to compare my design and building strategies to those used by the few individuals who actually proved themselves worthy enough to have faced and overcome the challenges of completing their builds. Once you have earned your full forum membership you will have access to a hugh increase in building information. As you read the builds your mind will crackle with flashes of insight and revelation.

Hey stevo, "I'm actually waiting to see how the tires and rims work out. I have checked with various vendors and No One makes Custom Dually Rims in that extreme Size. All the responses I have seen are to use custom adapters or make your own Rims. I can't fathom making a rim...So not sure what I will do..." There are custom rim makers that will build anything you can afford to pay for. One guy offered to build the 4 rims for the rear for 4,000.oo. That kind of price has made me entertain the idea of building my own. The more I have studied, the more confident I am becoming towards trying to fabricate my own. Given enough searching I believe one could find a useable rim and modify it with the appropriate center from another rim. Appears likely, it would take two rims, with parts of each, combined by welding, into one and maybe a wheel adapter as well to make it all work.

Hey Vertigo! Thanks for your advice on you build. I'm wanting and researching tumbler builds (both full and scaled sizes) I'm wanting to build one myself in scale so it would be legal to drive here in Alabama. Keep the post and pictures coming. Thank man!
