Sadly they are back ordered for at least a month.

Wish I could stream it somehow.

I got another set of rough 44s. Strangely they were fully functional though. They came out amazing. Now off to have them rebuilt. I assume it gets everywhere and will need to be thoroughly cleaned and sonic bathed.

I added this 120v solenoid for the air. So when i use my foot pedal it turns the air and the slurry pump on. Works so much better this way. I had great luck keep the slurry mixed by every 30 seconds or so pointing the jet to the bottom and mixing up the slurry mix. I could tell the slurry would be different for a bit.

I worked on my space e31 head and another Mikuni 44. Sadly the head has some severe pitting on number 1 and 6. It was covered in carbon. So you couldn’t see it. Strange.

I don’t think vapor affects the aluminum at all. I think it just picks the dirt out of crevices. It won’t pull off silicone or gaskets very easily. Doesn’t affect zinc. Doesn’t damage anything Today I tried way less glass and had the same results. This valve cover was rough. Looks pretty awesome now. Trying to get the appearce to be uniform is time consuming. I just gave up. I plan on doing 3 covers. One wrinkle red, wrinkle black and this one and decide which I like the best. It it just barely big enough for this cover. The head will be tough to fit and get the ends done. Shouldn’t be that bad though.

Not done with the cover yet. I will eventually do my head and my ford bronco oil pan and then my harada manifold.

Haha. It’s kind of a pain. Honestly for how much I needed done it would have been smarter to use a local company. But sadly none:(

I don’t know. I would say less then 500 the cabinet is pretty junky. If i was doing this for a living I would buy a stainless one.

Glad that reproductions are now a thing!

Thanks guys. Walnuts would be more abrasive then this by a lot. This is so soft that it doesn't even take sealant off or silicone. It's sort of looks fake its so nice. No idea on cfm. I have a small compressor at home that wasn't good enough. I could go about 1 minute before I need to take a break and let it recharge. Beads clumped a bit, honestly the amount of beads needed is so small. Tomorrow I will try much less glass and see how it works.

Well my home built vapor blasting cabinet works awesome. Uses a ton of air. So I had to bring it to my work. So happy! I don’t need as much glass to water. Maybe 25% glass.

I ended up using more of the water tight cord connectors, I also used a shower drain to make the vent pipe. Stock vent was just a aluminum cap with holes. This vent is just like vapor honing uses. Trying to dial in how much air to use. Might get to try tomorrow. I think I’m done for now.

Someone paid some dollars! If you need tuning advice contact David Premo. http://tuning4performance.com/

I won’t do any steel stuff. I got got all the fittings in the mail. Should work awesome. I went quick marine disconnects partial because I had some laying around and they are cheap. I like the fact that I can take the whole thing apart and put all the parts in the cabinet for storage.

They don't do much mikuni stuff these days.

Got the leds installed and sealed. Just waiting on some parts. Then it’s blasting time.

It’s a centrifugal pump. Basically keeps it agitated always. Even if you blow flow it would still keep it that way. I think the milkywater in the video will help me solve the glass/ water ratio. Mix till I get that color.

Yep awesome! I decided against the stainless thru Hull. Going all quick connect flo-rite fittings.

Dpan on facebook and a few guys hoard them. The going rate for a set of rebuilts is like 2,500-3k. Watch craigslist and have cash ready and be patient. They pop up.

Vapor honing said they only use one pump in their systems. If it’s pretty high percentage of water everything should be fine. I wonder what ratio they are using? I would even guess 50/50. Constantly recirculating should help.

I haven’t made it yet. I am just starting a build thread for it.

I have decided to make my own vapor/ hydro blasting cabinet. I have a bunch of Datsun parts (mikuni carbs, intakes, ac, head etc..) that I want cleaned up and shiny. I really really like the look of hydro blasted or vapor blasted aluminum parts. So I live in a tiny town, that's about 1.5-2 hours from a major city, but even that city doesn't have anyone that hydro/ vapor blasts so I am either shipping parts (expensive, and chances for damage) so it's time to make one. The basics of vapor blasting is a glass slurry mix (ratio unknown as of yet) of water and 170-325 Glass Bead (tiny beads) pumped in circulation through a gun that has compressed air attached to push the slurry at high speeds. Which doesn't damage or pit the aluminum, basically from what I read, it almost picks out the dirt out of the surface. It doesn't even affect zinc, rubber etc... I was just going to get a harbor freight cabinet and ruin it, but decided to look around the web first. I figured someone makes a plastic blasting cabinet. Which turns out they do! Simple, light and pretty cheap. I will probably end up using it not very often, so I would rather it not rust out. I ended up getting one off ebay for 175$ shipped! Retail on it is like $350. So I was pretty stoked. I wanted this size to fit a datsun L6 head. The one I bought: 31" version https://www.summitracing.com/parts/sni-40390 Smaller: 22" version https://www.northerntool.com/shop/tools/product_200136624_200136624 Pump: Next was a slurry pump, I wanted centrifugal so that the slurry wouldn't ruin it. I decided on this one. According to vapor honing videos you want good psi from the slurry pump, this one is 63 psi. I will be going from 1" down to 1/2 or so for the gun, so that psi will be lower. https://www.amazon.com/gp/product/B00TQCSUZK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 Lightening: I wanted to be able to see inside and I would rather not get electrocuted. I found some neat LED's on amazon that are meant for fish tanks. They are 12v that use a small ac adapter and are fully waterproof. I got 2 warm white 12" long ones. https://www.amazon.com/gp/product/B00OP3P1AM/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 False Bottom: The blasting cabinet came with super super shitty screen for the false floor. Which is mild steel, so I threw that in the trash. I have a bunch of stainless grating (I own a brewery and we have lots of scrap) that I was going to use. But I was worried about damaging the aluminum on sharp stainless. Then I had an idea! Plastic grating and I actually had some laying around! It's a fiberglass/ plastic grate meant for standing on. I cut it down into two pieces and she fits perfect and are easy to remove. I also have a small stainless basket for smaller parts. It has very small holes so it should keep anything small from going down to the pump. Through Hull: I needed some way to get the slurry out without leaking. I decided on a cheap through hull for a boat. Which fits perfect. The pump is 1" so I decided to run 1" hoses from the cabinet to the pump and back to the cabinet. I went stainless, which is a giant overkill. But whatever. I will also pump a wide screen on the through hull so it doesn't suck anything large into the pump https://www.amazon.com/gp/product/B001HC0R6W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Water tight Pass through: I will use liquid tight cord Strain Relief Cord Connectors. You can buy them online or at any homedepot. They have a few sizes. I should be able to use them for the compressed air into the cab, slurry and 12v. So it will be water tight. 120v Foot Switch: Since your hands will be in the machine I decided to use a foot switch for the slurry pump. https://www.amazon.com/Power-Maintained-Latching-Foot-Switch/dp/B004LJ6MYE/ref=sr_1_1?ie=UTF8&qid=1520527436&sr=8-1&keywords=120v+pedal+switch I will hopefully finish it this weekend, I will use marine 5200 on all the through hulls. Should be a fun project! Videos of vapor blasting honing: https://www.youtube.com/channel/UC2DdHXu6oFqUWZ-rNNR7Bcg Some of the before and after are amazing.

There is a few guys with them. Mike Watanabe has like 4-5 sets. Also a few guys import them from Japan, or watch craigslist. Comp intake might be harder to find. There is a mikuni facebook group with a bunch of rebuilders on it. They always have stuff. https://www.facebook.com/groups/945925058849881/
