My 6-71 Blower rebuild, Part 15: Custom machining a Magnesium carb adapter plate.

Very nice video! I'm actually about to do a 8v92 and will be referencing this video! I also really like your home made fly cutter. That was trick and simple.

Hoo Lordy. Not only are there way more steps to converting a stock blower to automotive use than I expected, a lot of those steps are high precision,and I specifically refer to the drive gear step(s). Get anything wrong,not only do the tolerances go out,the blower can make very expensive noises very quickly. Every one of those steps was written in blood and/or money. The hot rod community had to figure those steps on their own. And somebody got to pay for anything they got wrong. Really appreciate the effort you took,not only to get the blower just so,but the video would have significantly added time and frustration. Great job,hope you get to bolt it on to your latest rod real soon. Cheers.

Love it!… great job,… would you be interested in selling your design coding?

Just watched all of these videos in this serious. Thank you sir for the excellent entertaining and informative videos. Helped me a ton!

Thanks for watching! After a two year hiatus where I was just too busy to build stuff, I am back doing projects again. I will give you the first hint of whats next. Today I will be testing a motorized linear Plasma cutter guide. I have all of my raw video already shot, and should start posting the series next week. Stay tuned!

I Also Built My Own Carb Adapter To Be Boost Referenced For My Edelbrock Carbs ,Thank You For Your Videos !!!

[@MakerCave]

Thats very cool. I have not worked on Carter AFB's (what became the Edelbrock "Performer" carb) for about 40 years. Do they have an easy way to boost reference through the base-plate? I just don't recall after so many decades of Holley only.

@@MakerCave I can send you the link that I found to boost reference the Edelbrock carbs thru an Email if you like

@@gregschultz2029 Well, we can't E-mail through KZbin, but you must be talking about this example from the HAMB: www.jalopyjournal.com/forum/threads/boost-referance-edelbrock-afb-carbs.361134/ Looks like a very simple modification that just requires simple cross drilling in the plate. Should work out great! There seems to be a fair amount of confusion out there about boost referencing, but I 100% agree that providing the "below blower" signal is highly worthwhile to allow the Power Enrichment circuit to function as intended with a draw through blower. Your boost ref will help avoid a full throttle lean condition. Good luck getting her together!

Yes ,That Is The One I Made ,Thank You For Your Response !!!

Why magnesium and not aluminium? Sorry if you already told somewhere but I missed it.

Funny that you ask, and I actually give a partial answer in the video description, above. Click on "Show More" below the description to see the partial answer. The whole answer is that it was an accident. 25 years ago, I was building a blower for one of my cars, and was on a shoestring budget, I mean even spending $20 was rough then, but I was determined to have a blower. My Father in Law had a good friend in the scrap metal business so I asked him "can you talk to your scrap guy, and see if you can get me a piece of 3/4" aluminum plate for cheap?" The plate was about 8" wide and about 3 feet long, and it was crusty, I mean really filthy, so I paid scrap price, $5 I think, for this huge piece of plate. I scrubbed it off with a DA sander, which took a really long time, and finally got a smooth surface on it. I used a hole saw to cut the venturi holes in the plate, and laid out all the mounting holes by hand, drilling them on my old Craftsman drill press, the only shop tool I had at the time. I noticed that the plate drilled and cut really nice, and seemed very light after it was done, but didn't really dwell on that. I just thought that it was a really nice alloy of Aluminum. I took the extra plate, which was nice and shiny and put it back on the shelf. Two years later I went to move to a new house, and I discovered that the spare plate was just as black as the day I first obtained it two years earlier. It dawned on me then that this was not some ordinary aluminum. I shaved a few chips off of it, put a couple of drops of lighter fluid on the chips, and lit the fluid. After about 10 seconds the chips flared up an intense bright white, like the color of a 4th of July sparkler, which usually has some magnesium in it. That is how I confirmed what metal it was. I kept it around, in case I had to make another plate someday, and here it is. A piece of aluminum plate this big is close to $100, so the final answer is, I used it because I had it in inventory. It just happens to be icing on the cake that Magnesium is only 2/3 the weight of aluminum, and stronger per lb than aluminum. Thanks for watching my video!

I did read the description but I thought it was odd to use more expensive material so I thought maybe there was some benefit I did not see. But I now see that it was somewhat of a coincidence :) Thank you for making the videos, I hope I get my other projects finished soon so I can get working on my 6V71!

Uhhhh where's the video of the supercharger installed and running??? You'll have to imagine large, bold text.
