Siphon feed blasters are practically useless , unless you are only sandblasting a small area .
The sand , as well as the air , must be absolutely DRY . I have two air dryers . One near the compressor , and one on the sandblaster .
An 80 # pressure feed blaster and a 5 HP compressor should be completely adequate .
Freshly sandblasted steel will rust rapidly . PPG recommends that the steel be re-coated a half hour after sandblasting to prevent " flash rusting ".
To help avoid warpage , keep the nozzle moving in a series of sweeping motions . Rather than concentrating in one spot . You can't " blow through " sheetmetal with a sandblaster , unless there was nothing but rust there anyway ..
A rotisserie definitely makes life much easier .
I usually blast between 60 and 100 PSI . I start at 100 and when I get down to 60 PSI , I take a break and let the compressor catch up .

What primer do you use ? Do they have it in "rattle cans" ?
My 57 has rust holes in the floor pans and trunk, so I am expecting to "burn through" more than a few spots.
I'll reset my compressor and regulator to 100 psi shutoff.
I liked the rotisserie more, after I saw yours and how well they work. Laying under a car sandblasting and welding isn't handy. I'll be replacing sheet metal also.
Thanks Charlie

I got side tracked this summer , so I need to up-date this thread .
I got my 394 motor all finished ;
You can see my engine build thread here ; https://classicoldsmobile.com/forums...ine-build.html
And my carb rebuild here ; https://classicoldsmobile.com/forums...-4gc-carb.html
Now , the next order of business is to put that 394 back into that frame .
I proceeded to make steel motor mount brackets , using the plywood ones that I had made previously .
I started with a chunk of quarter inch plate from the scrapyard . I simply put the patterns on the steel and outlined them in spray paint ;
Straight cuts were made with a skilsaw and a carbide disc . Curved cuts were made with a jigsaw with a bi-metal blade .

I just got done moving , so I got some " puttering " time for my Olds tonight .
I needed s set of exhaust hangers , I'm converting to dual exhaust . and on the right side someone cut off the old pipes at the rubber section and half of the hangers went to the scrap with the pipes .
Fortunately Pat (deadds ) had some that weren't too bad .
To take them apart I first drilled the rivets out with a 11/32 drill . You don't need to drill all the way through , just enough to weaken the rivet .
Next , I punched them out with a center punch .
Then I bead blasted the metal pieces and painted them .
Next I need some rubber to make new rubber parts . I was thinking of buying a new mudflap from a truck place and cut the rubber strips from that .
Does anyone have any other ideas ?

What you are seeking, and should use, is something called "masticated rubber." It is rubber reinforced with cotton thread. If not what the manufacturer used, it is awfully darn close. When I rebuilt my exhaust hangar, it is what I used.
My advice is to measure the thickness of the rubber on the hangar and get some at least as close to that thickness as possible.
Here are some suppliers. The first in this list gets my recommendation -

Dave , Do you still have some of that material ?
I need 1/4 in and 3/8 in thick . I only need a few pieces , maybe 2 and 1/2 wide by 6 at the most .
If you have some extra , I would buy enough from you to do four 3/8 straps and two 1/4 straps .
I would hate to pay $125 for two 36 X 36 sheets when I only need a few small pieces .
Please let me know . Thanks , Charlie .

Yes, I am sure I have some material left. I do not know how thick it is. I do know I only have one thickness. I will have to find it, and report back.
Why do you need two different thicknesses? A quarter inch (1/4") seems pretty flimsy to me in this application. If it were me I would go with the 3/8" in both locations.

I have checked. The roll of masticated rubber I have is 3" wide x 1/4" thick x ?ft long.
I do not know if that will work in your application?
What I did, as you can see in the photo is use 2 layers of the material. If that works for you, let me know how much you need, and we'll work out getting it to you at a reasonable cost.

Dave ,
I'm going to need about 6 feet of the strip .PM me with price and payment info . Thanks , Charlie

Here I go . One step forward , and two steps back .
I removed the bellhousing to install the clutch fork and throwout bearing . And it doesn't fit . The '63 Olds clutch fork and bearing were way too "tall" .
So , what to do now ?
I went back to pics of the '63
"98" Sport coupe with a 4 speed and discovered a strange forged clutch fork was used. Using google images I determined
that it was a 60 thru 84 Chevy truck clutch fork # 3765372 ;
So I ordered one off E=Bay and a "short " GM bearing too . I will see if this combo will work on a few days . Stay tuned .

I finally found a solution to my problem .
The Chevy throwout bearing wouldn't work , because I have a "Long" style pressure plate . (too small )
So I used the '63 Olds throwout bearing with a specially made collar .
I made a drawing of what I wanted and took it to a local machinist named Bernal .
Bernal is a Cuban refugee , and he used to make parts for old American cars when he was in Cuba .
I certainly found the right guy for the job . Here's a couple of pics ;

I then needed to put the trans in , but I had no helper .
I thought for a while , and then went to the hardware store and bought two 1/2 bolts 10 inches long .
I lopped the heads off and used them as guides to slide the trans in by myself ;

I first read that tip about using the 1/2" bolts with the heads cut off in a magazine in the 60's. I have used it many times but I never used 10" long bolts. In my youth I could use the bolts and stab a 4-speed my myself. Not anymore. I will have to use a floor jack if I do one again. Looking really good Charlie.

body work
I took a break from the chassis assembly to work on the body for a while .
I set up a " body shop "
There were two small spots on the bottom rear of each wheelwell where the metal was rusting through from the inside .
Probably because dirt and debris had collected there . This was the only "rust " on the body .
I could see pinholes in these areas , so I took the "pick" side of a body hammer to figure what was solid and what was " alpine lace " .
Then I took a die grinder and a thin cut off wheel and cut out the "alpine lace " .
I got some 20 guage sheet metal and hammered and shaped metal patches and cut them to the size of the old pieces .
They fit pretty well .
Then I had a friend ( who is much better welder than me ) weld the patches in place ,
I ground the welds smooth .
So now , with a little lead , and a lot of finish work , nobody will ever know the patches were there .

Well , the hurricane threat is over , so I got back to work again .
I got a lead kit from Eastwood ;
Then I wire brushed the patch area clean , and heated it with a Bernz propane torch and applied tinning "butter" .
Then I applied lead while carefully heating the panel and the lead . Shapeing the lead with the wooden paddles .
I then filed off the excess lead and shaped it with a vixen file ;
I hand sanded it ( wearing a respirator ) and it looked like this ;
A quick coat of black paint reveals that it may take some additional work to make it perfect ;
The beauty of lead is that I can wirebrush the paint off and apply more lead to some low spots . Then file and sand again .

I had a long crease in the quarter panel and it was difficult , if not impossible , to straighten with a hammer and dolly .
I wire brushed all the paint from the area .
I bought a Harbor Freight stud welder for this ( and other ) repairs .
I welded studs every couple of inches along the crease .
I then used a slide hammer to pull the crease out .

I found the lead filling process to be pretty straight forward except... then it comes to filling vertical surfaces. THAT, was challenging as gravity is not your friend here! I'm sure a professional that was fluent in lead filler would have been able to instruct me, but I did it the way I did it and it took awhile and I wasted A LOT of lead.
Overall, I much prefer plastic filler and would use it for 98% of repairs, but I think that even today, lead filler has a place and is a good skill to know.

Also , when you heat the lead , the surface will turn from a dull gray to a shiny silver just before it melts .
That is where it is in the " plastic " range , and can be spread . Alternate use of the torch and paddle can keep the lead in the " plastic " range .
There is only so much " instruction " to this . And the rest is just practice . Just like learning to weld .
I've also learned that this stuff is harder than Chinese arithmetic to file . You can leave the " cheese grater " in the toolbox .
It takes a vixen file and a lot of effort to file it .
I like lead for it's permanence . These repairs will probably last well into the next century , Bondo ? Not so much .
