Talk with Bob, Hammond Barn proprietor, he is almost sure to let you try the sandblast cabinet at the barn. Assuming that you don't want to take the CV joint apart to clean out abrasive that will work its way into every unprotected crevice, I would not trust the CV boot (even though it does a pretty good job of keeping blasting road grit out). The protection needs to be both grit resistant and resilient to absorb the energy of the flying grit. Think about how hard it is to blast firm rubber off of a steel substrate and how well the blaster works at taking relatively brittle material like paint off the same steel.

Sand blasting.....
One as to be careful about abrasive creeping into bearing or any other device that is greasy and impossible to clean up......
It is ill advised to sand blast a complete running frame with wheels, t case, tranny engine..... UNLESS... you intend or plan to disassamble everything as part of the rebuild......sand.... dust... grit will creep in the almost impossible places. Blasting media can reduce this problem slightly...... walnut shells left over would be less damaging than sand. In the Blasting cabinet.... which has limits as to the size of the parts...... is loaded with aluminium oxide..... almost as bad as diamond dust if it gets in bearings..... the grit is so small it gets into everything including your nose.... yes it gets there even with a sealed cabinet..... sealed is a "big" word. We use a shop vacuum to remove the air born dust from the cabinet.... life expectancy of a guaranteed for life HD vaccum motor bearing is about one year of intermitent use..... It may be easier to sand blast the axle using the big tank outside with the pleasant weather forecast of this weekend...... I would suggest you look into buying some white quartz sand at BMR.... grit size .30 or some black beauty.... silicone free at Princess..... We are out of stock st the barn.... we prefer the cheap quartz .... cuts fast and we get it by the skid...... about 3200 pounds..... makes for a very smooth riding Ford on the way home..... tend to polish the pads on the helper springs. Stuart gien me a call to sort out our weekend schedule.... Boob

Electrical tape works great for protecting bearing surfaces that you do not want blasted. Use 3 layers and you will have to actually try to get through it to blast it off.
Electrical tape is soft enough that the sand just bounces off it. Glass Bead will help as it is less agressive than sand. But it is not good for removing scaly rust. Matthew

For me, I'd pick one of my all-time favourite tools "the poor man's sand blaster" I call it - a cheap angle grinder with a rotary wire mop. Cleans rust, paint, you name it right off anything, and produces very little abrasive by-product. I use mine all the time. The only thing it can't do is get into tight spaces. For that I use a cheap Dremel knock-off with a tiny wire brush
