Part 10: My 76 Mazda RX-5 Cosmo Restoration - Shaved Door Sheet Metal

[algurdian]

Love your work ...but maybe you should of used the old tried and true hammer-weld method.

I had great results hammer welding my my 65 mustang quarters..no warpage

[henryv8]

Great vids dude, I spent a night really enjoying this. With the patches, if you make them a couple of mm smaller you will get more room for expansion and use the weld to fill the gap. You will get alot less distortion.

[aaroncake]

@henryv8 There was actually about 1MM between each side and the door, I just don't think the video showed it clearly. Really, I should have filled the existing handle holes instead of cutting a big chunk out of the weakest part of the door. :-)

hay aaroncake just wanted to ask you something isnt a 12a a 1.2 liter engine not a 1.1 liter engine. GO THE MIGHTY ROTARY

[aaroncake]

@guilmongrowlmon It's actually 1.1 litre.

[sjaakiepot]

there was a video i found related to yours, hes also using air to cool it down... some say aircooling or watercooling is not smart to do.. others say it is.. looks like its all personaly :P

[aaroncake]

@sjaakiepot Based on using both methods for my doors, I'd say that I'll only force cool if I want to shrink the metal. I was able to get the best results when keeping the door a constant temperature. Which probably has something to do with the fact that I cut out the wort possible section to patch, taking all the strength out of the door stamping and making it far too easy to warp. I water cooled the rockers when I filled the trim holes and didn't get any warping.

[sjaakiepot]

hey man, how are you doing on part 11 ? excited to see it lol :P

[ptdude805]

man i remember seeing your site about 8 years ago when i made my spudgun. glad to see your still working on projects.

[aaroncake]

@ptdude805 Haven't done any spudgun stuff in a while, but suddenly now I have the urge to dust one off and take a few shots.

[bstnguy9]

The best part was when you said you had a girlfriend....lol. We all know you dont have a girlfriend.

[aaroncake]

@bstnguy9 Oops, my mistake. Let me rephrase the statement so it's true then: "I haven't done that much pounding since the last time I saw your mom.". Much better and in line with reality.

[sjaakiepot]

when im welding i usually use a wet towel.. weld abit and then cool it off with the wet towel, it works the best id say... but still metal will always work a bit...

[aaroncake]

@sjaakiepot I've been told that a wet towel or forced cooling should only be used if you intend the metal to shrink. After I warped the first door I asked a few panel beaters for advice and they said the best thing I could do was to just work slowly and keep the metal at a constant temperature to where it could still be touched. But it would have helped if I didn't cut out the weakest area of the door. I should have filled the stock handle hole, then smoothed the top separately.

What do you do for a living?

[aaroncake]

@xboxershawn In real life I'm a computer tech.

[Hazchem]

I can honestly say I get excited for each new part when I log in to youtube each time. Keep up the work and awesome videos :D

[wild13bt]

Where's the freakin engine build!!!!! hahaha good work :)

[aaroncake]

@wild13bt A little secret is that the engine went together last weekend. Will it be the next video? Maybe...

[fc3chris]

@aaroncake are we expecting anything crazy like the engine in your fc? :)

[aaroncake]

@fc3chris No, it's not going to be some 500HP monster. But it is going to be very unique, set up for low and midrange daily driving. In a way, it will be my opinion on what Mazda *should* have built instead of the 13B-REW.

[kentdoNEthing]

"a little more pounding now prolly means a lot less pounding later. which is what she said!" hahaha not only your vids are informative, you also know how to keep your audience's attention. LOL good stuff aaron! keep it up!

[aaroncake]

@kentdoNEthing Good to know. :-) I've actually been rather shy about the "shop talk" being in the video because I am a bit concerned with alienating/disgusting/angering­/exciting people. Maybe if I slowly ease into it.

[tsherwoodrzero]

@aaroncake you've got nothing to worry about Aaron. Anyone watching these videos is a rotary enthusiast, has seen the lounge on the rx7club and already thinks you're awesome.

[noholo1]

really enjoying the vids

[Julzilla]

"i haven't done this much pounding since the last time i saw my girlfriend" bahahahahahaha rofl good call!!!

[Russell042]

Cant wait to see your next vid, intresting project so far.

[dumbassmax]

learn with your mistake in this video you seem to learn a lot haha. i really enjoy your vids.

[SpideyFan6010]

@dumbassmax least he didnt edit out him pounding away at it and disguise that he did if perfectly when clearly it was the wrong way. and didnt go as planned for those who didnt know. plus it gave us a couple quick anecdotes. so ehh it was worth it lol

[jngtigmsmff]

Keep up the good work
