Part 20: Media Blasting The Front End - My 76 Mazda RX-5 Cosmo Restoration

[Strike86]

Came here to find out if it's easy to rebuild a rotary engine (thinking of buying an FB RX7 which looks pretty tired), ended up watching all your videos on this car so far.

Subscribed since I'm really looking forward to seeing how this turns out - thanks for all your videos!

[DizzyTheSuccubus]

Love the videos, I recently got an N/A 86 RX7 and your vids about rebuilding the engine has made me a little less concerned. Are there any other vids on the Rotary engine that you would suggest anyone to check out?

[aaroncake]

@DizzyTheSuccubus I don't think there are any as detailed as my rebuild video. Definitely check out parts 2, 3, 4, 7 and 8 of my Cosmo build for more engine work.

[MrNashAP]

Aaron you taught me a lot. More vids please.

[DarkPrince013]

Moar video! People are waiting for it... What are other names of the Cosmo? Maybe I can find one somewhere near Florida

[aaroncake]

@DarkPrince013 Far as I know the Cosmo was only sold as the RX-5 and the Cosmo. I think the piston version was the 121. As for the videos, I have been working hard but since this is auto show season and I just got back from vacation, I also have not done much in the past 2 weeks. I intend to finish ALL the front end sheet metal in the next video because I'm sure everyone wants to move onto something else (I sure do).

[lan0429]

I love all the videos on this car, their are not many of cosmos left. So thxs for the video can not wait for the next videos to came out. :-)-<-<

[ponchoyo]

That's a lot of frickin work man.

[Jx1x3]

ok Aaron, I bet you're a busy guy, but get with the filming and posting! just messin but hurry!

[Dmurphy527]

Aaron,

Great job..I'm looking for a dash (and other assorted pieces) for my 76 Cosmo. Do you know of any places to find parts?

Thanks

[aaroncake]

@Dmurphy527 Try the Ausrotary forum. I've also had surprisingly good luck with eBay.

[jonathan300985]

Dude! u r a rotary genius!... 1 video of swapping a fd engine will be the greatest contribution for any fd owner on the world... specially for those who aren't experienced mechanics...

[aaroncake]

@jonathan300985 That's not part of my Cosmo project, so it won't be in this video series. It's also likely not something I'll ever produce because I don't own an FD and don't plan to.

[TheFostone]

caint wait for the next part

[MrKlemensas]

Mr Aaron, when we could expect new video? i mean part 21, coz personally me- i can't wait 4 it

[aaroncake]

@MrKlemensas I cannot say for sure. I'd like to wrap up all the front end sheet metal and be done with sheet metal episodes, so it may be to months before I release another video. This is a busy time of year for me with car shows, birthdays, and a vacation. :-)

[MrKlemensas]

@aaroncake That's a bit sad, but oh well i'll will be waiting 4 new episode :)

[aaroncake]

@MrKlemensas But on the plus side, it will be the last sheet metal episode for a while! As soon as the engine bay metal work is done, the engine goes in for mockup and I start with the FUN fabrication.

[MrKlemensas]

@aaroncake that is actually a big plus side :)

[Aunubus69]

Keep up the good videos and thx to the reply also you'll get a new GF soon haha they are a dime a dozen.

[kentdoNEthing]

aaron, you still got your jokes. hahaha! stroking that nozzle too. LOL

[mx3sleeper]

comming along pretty good now, almost engine times

[aaroncake]

@mx3sleeper It will be a little while yet because I still need to do the engine bay metal work and then paint it. The inner fender areas need to be all repaired and welded up before i can think about painting the bay.

[mx3sleeper]

@aaroncake Im just optimistic.

[aaroncake]

@mx3sleeper However I'm pushing hard (that's what she said) for the front end metal work to be done by the end of March so that the fun stuff can begin in the spring. Oh and probably only one more highlu summarized sheet metal episode.

[tsherwoodrzero]

Aaron, someone needs to tell your girlfriend that you NEVER go Ass to Mouth...

[cbkidder]

I love the intro, very 70s Japan: もしや。。。コスモだよ (well...it's a Cosmo, you know)

How satisfying to blast it back to clean bare metal. You must be very eager to get that rust fixed so you can paint it and get the engine back in. Please keep posting these videos, they're great!

[aaroncake]

@cbkidder Do you know the meaning of the Japanese in the intro? If so, can you translate and post it? I'm hoping that within 2 months I'm done the metal work to the point I can get the engine back in and then start the fun stuff.

[cbkidder]

@aaroncake You got it.

man: Moshiya, Cosmo da yo

woman: Cosmo makes me free~

man: Cosmo AP, ragujuari- spo-tsu

the first line has a slangy feel, but here's my rendition:

man: is it...yeah, it's a Cosmo

woman: Cosmo makes me free

man: Cosmo AP, luxury sport (coupe)

[aaroncake]

@cbkidder Excellent. Thank you, as I've been trying to figure it out for a year. The last line is easy, the prior lines are much more difficult for someone unfamiliar with Japanese.

[drphyco500]

quote of the day. "honey why do i have sand in my mouth?" LMFAO

[DarkPrince013]

I lol'd so hard at the media blast in every hole... Then in your gf's mouth. Wonder how it got there...

[mdobilas]

Honey, why do I have sand in my mouth?  AHAHAHAHAHAHAAHA

Great video as always Aaron. This is the subscription I most look forward to seeing a new episode of.

[Aunubus69]

Haha your gf must really love you most would be like that shit again i'm fucking done lol

[aaroncake]

@Aunubus69 True story, but it actually happened last year. No girlfriend rigtht now. :-)

[Julzilla]

Fire department called again? Pray do tell more lol

[aaroncake]

@Julzilla Last year I was blasting my RX-7 diff in the alley beside the shop, so some crackhead called the fire department because they thought the dust was smoke and that I was "lighting something big". The firemen were not amused but said "Nothing wrong with blasting". Turns out one was restoring a Mustang so I later blasted a box of parts for him.

[davemiii]

Ok, on a more serious note - I'm pondering the same setup for my garage restoration. How well did it work to keep the media out of your shop? I need to keep my media out of my garage to keep my wife off my ass. I've also been thinking of hooking up an HVAC filter to a box fan to try and keep the dust in the "ghetto booth" to a minimum. Nice idea on the hood. Did you also wear a respirator under the hood?

[aaroncake]

@davemiii It worked fairly well but the fine dust is going to escape unless you can set up a large negative pressure or get a LOT of airflow through. There wasn't much media spread around the shop (a little) but there was a thick coat of dust. It just blows off and then can be swept up even though it looks like a massive mess. It's hard to avoid creating some kind of big mess when media blasting. I didn't wear a respirator under the hood because there was enough airflow to keep the nasty out.

[davemiii]

"It's about that time in the day where one starts to get tired of their crazy extended family.." Man you got that right! Back from the in-lawns and I got my adult beverage (some Glenlivet) and the laptop all ready to watch some Cosmo goodness. Hey I wonder if they named the drink after that car? Aww yeah you KNOW they probably did

[RX7Ronin]

"Honey, why do I have sand in my mouth?"  LMAO

[jefa1234]

yeah a new vid! :D I love this Restoration...every day I came here to see if had a new part! And it's a awesome work!

What's coming next?

[CHIBA280CRV]

Hey Aaron thanks for the Christmas gift video' Merry Christmas and a Happy New Year"

[puafia]

Wouldnt it have been easier to strip the entire car and media blast, rather than doing sections?

Merry Xmas and thanks for the cool videos. Keep them coming!

[aaroncake]

@puafia Normally that's what one would do. I didn't do this basically due to lack of space, and that I'm only one person that can only work on one area of the car at a time. Plus, once blasted, the entire vehicle would need to be epoxy primed which I just don't have the space for. The front end will be the last major blasting. Then every other panel will be stripped (chemically or mechanically) and primed one by one as I get to them.

[HitokiriRaiden]

Very nice man. And Merry Christmas hope you have a good one.

[mrknight410]

Awesome vids..... merry Christmas and happy new year :)

[MrYoanEmond]

Thx for the vid Aaron. Im waiting for all of them.

[mdh16hunter]

As always, good job! Learned something too

[1SWEETRX7]

Excellent video Aaron, Merry Christmas!

[Jx1x3]

wow that engine bay looks sweet!!! hmm I wonder if the media can get inside a bung hole..who knows. merry Christmas and happy new year!

[aaroncake]

@Jx1x3 Oh yes, if you're not wearing a protective suit, you'll find media everywhere including the butt crack. It gets blown through the fabric of most clothes quite easily.

[livehumansinside19]

Excellent as always!

[magnusrx7]

Nice job!

[Nismoreload]

Great stuff again!

[gragoo]

looking good and looking like you have more metal work to do :)

[sacheus]

Merry christmas budy.
