So don't hit walls at WOT?
 

Here's some pics of my most recent crash... Was about 50 yards away and runnin the E-maxx at WOT and out of nowhere comes this building... I had heard reports of a stray one roamin around in the park where we were bashin but I thought the noise of pinion mesh and Mamba Monster beeping all over would scare off any undesireables... Anybody ever have a Ti hingepin break into 5 pieces like this? Maybe I'm special after all! :whistle: On to the pics... Meant to post this in the E-Maxx forum but it does have an FLM chassi in it... I guess it fits here too...

this year i did crash my carbon fiber 8ight into the ground at about 40mph (Newton's Three Laws of Motion shouldnt apply to flying buggys) i bent a titanium hindge pin into a U shape, but i havent ever broken one into pieces

the pictures are good proof but the logic seems flawed. Can anyone else verify that you should NOT run into buildings at WOT?

side note: I love the acronym WOT. I sometimes roll around making wide open throttle noises while saying "wot". WOT WwoTT WWWOOOOTTTTTTT WOTT WOTT WOTT WooooOOOOOOOOOOOOTTTTTTTTTTTTT (shift) WWOOTTTTT WWOOooootttttttTTTTT (shift) WWWWWOOOOOOOTTTTT
etc., etc.........................

The GA bulks with a broken Tony's screw in it might be a lil more proof... Or the way I had to use the dremel to cut what was left of the hingepin out... The parts left in the bulkhead were both mushroomed out on the inside so i had to push them towards each other and cut the swollen ends off... Ha... I just used mushroomed and swollen in the same sentence... On a side note, Ti sparks are awesome!

You probably didn't know that ahead of time.....grinding Ti is not a good idea...

I have run into stationary objects w/my buggy at WOT several times...never w/good results

Gnarly! GA bulks are tough!

Not good? Oopsie! Is cutting considered the same as grinding? :neutral: O well, if the smoke from the casino I work in don't kill me I can blame it on Ti dust! :sarcastic:

@ kcaz25... 7075 bulks with Strobe braces, k'heads, UE EXT 15mm suspension, Ti skids (that I havent cut or grinded), Gen IV saver and Ti steerin links is pretty tough! I guess the Maximizer beadlock, the hingepin and the broken screw were a pretty good tradeoff for what coulda broke :yes:!

Cutting is different. On second thought, with the size of the hinge pin and speeds the dremel is only capable of, there really isn't much danger, just a lot of white sparks.

Issues come up when people use the same grinder for different materials - especially aluminum. Aluminum will embed in the grinding wheel, and once it heats up, can cause the wheel to explode.

I'm a welder and I have never heard that before in my life. I've used a disk covered in alum. to grind steel lots of time, no blown up disks. Unless you have personally seen it happen, I think whoever told you that is full of shit lol.



On that note though...wierder things have happened, pure oxygen and oil has been known to explode.

I spontaneously combusted once...

I also weld and weird things have happened to me as well. Pure Oxygen and petroleum products don't always mix..:whistle:

Was that before or after the pee issue?!?!?:surprised:

Yeah, that was presented in the OSHA safety training we have. They did show it happening on video, and I personally know of two guys I work with that have said it happened to them. Might be overly cautious for "real" people (as we call them) - our safety standards are often waaay over the top.
It better be true, 'cause all through our factory we have duplicate grinding/vacuum stations - ones for aluminum, and the others for steel. Titanium is only processed in buildings that have stricter environment controls (single material processing areas).

JT is right on this one, alum just loads up the wheel media and you are then effectively using an alum 'coating' to "grind".. not brilliant. Heat is normally carried away from the bonding material/grinding media by the material being removed. A loaded wheel will in fact overheat the bond and bad things happen. This is more an issue for thinner and smaller wheels. A loaded wheel will clean itself slowly when used to grind materials harder than the embedded aluminum. But it's stupid. You won't get a good edge on anything that way. I exploded a wheel my first time with a surface grinder back in trade school... it made a real mess of the sheetrock in it's path and left a massive gouge in the mag table. All I did was misjudge my cut depth.

I recommend either a good silicon carbide stick or better yet a diamond wheel dresser, they should never be used with any junk on them. If only from a balance standpoint.

Also if you think I am full of shit I've been a fabricator/machinist/mechanic for ~20 years. Not greasing the O2 regulator is about the second thing you learn in welding training, right after learning how to use a striker...:rules:

No offense krawl, but them's the facts.
