Come on - Thunderdome, not Pokemon.
It DID arrive today and is waiting for me in my mailbox.
eng1nerd what is your bar made of? J5's is made of L6 steel.
Awesome, mine is A36 steel.
The contenders! I was up until midnight last night (6 hours and 29 minutes ago) working on this and a spreadsheet for the scoring data (totally self taught in both image editing and Excel and not that proficient at either).
Decided to use JB KwikWeld to glue shut the Altoids tin last night. Cleaned the lid and bottom mating surfaces with acetone first. Should be plenty set up by this afternoon.
I'm almost done (just have the final scraping tests to complete) after about 4 1/2 hours. What takes the most time is making sure I get video and then taking pics throughout the process. I already have a clear winner. Should I post the winner before posting the spreadsheet with the results or wait until done with it so everyone can see the scores? I don't know when I'll have time to get the videos edited and uploaded- that will take several more hours.
Oh, and I took one for the team, too. At about 1/4 the way through testing, I thought I broke my left hand but it seems to just be a REALLY bad bruise on the meaty part below my thumb- pretty sure it will be all purple tomorrow as it's already swelled up.
Your call, or vote by the audience.
I'll get the results up this evening. I need to fix something to eat and finish filling out the spreadsheet.
eng1nerd pry bar initial impressions:
Doesn't feel heavy in the hand and with the added lanyard, makes gripping it easier. A little rough around the edges as well as the pry/scrape edge not being finished real smooth but it is straight.
johnny five pry bar initial impressions:
Feels heavy in the hand with finely finished edges and chamfers in several places making it comfortable to hold and fiddle with. The pry/scrape edge is smooth as glass as well as having sharp edges, although finished with a slight radius.
Here are a few photos before the carnage, in no particular order. Sorry the pics aren't better as I had planned to have a new camera (wanting to get back into photography) by now but that's on hold because of stuff going on at work, so I used my several year old point and shoot camera.
In several places throughout this thread as it pertains to the contest, I will refer to the eng1nerd pry bar as E1 and the johnny five pry bar as J5.
While the E1 pry bar isn't as finely finished, I thought it might hold up better, but it came through the Thunderdome with some damage. I never would have thought that the J5 pry bar would have held up like it did with that thin tip, but apparently, L6 steel is super tough stuff. It came out almost unscathed in the Thunderdome.
The winner is johnny five! Final photos below as well as the spreadsheet with the scoring.
Then there's this.
Congrats johnny five
Here's a wider look at the testing ground since in the videos, they are all zoomed in on my workbench (built it from scratch myself 15 or so years ago). All the videos have a number at the end of the title which indicates the order it was taken. My camera starts with 0000 so video number 1 ends in zero.
Forgot to scrape lid of Altoids tin with J5 pry bar.
I tried to be as fair as possible throughout the testing and realized I hadn't tried driving the E1 pry bar with the bevel facing up thinking that might make a difference. See below.
I realize the fact that the E1 pry bar was used first on the cinder block probably resulted in it having a more difficult challenge going through because of the added structural integrity of a whole block. Had the testing been much, much more close at this point, I would have grabbed another cinder block and used the J5 pry bar first. At this point in the testing, the J5 pry bar was already the clear winner. The E1 pry bar had already sustained a significant amount of deformation on the pry edge and mushrooming on the tail end prior to the cinder block test. I have pics of each pry bar just prior to the cinder block test if anyone is interested.
That is really cool. Well done, all parties involved!
johnny five, did you heat treat that L6? I'm really surprised how little it deformed taking that much abuse.
He may not have heat treated it, but when grinding it may have cooled it in water after getting it hotter than realized.
I think I missed the post of what they each were made of.
