grit blasting

Post by chriss »

just wondering if anyone has got or used a grit blasting cabinet for cleaning small items, if so are they worth having

Yes they are fantastic. If budget allows get a pressure fed one not gravity fed. You need a.large compressor aswell. There is no better way of cleaning than blasting.

I would suggest that you might find some internet research of some benefit as far as the medium, grit, is concerned. Many professionals have found that the use of glass or plastic beads do a better job on thinish metal panels or just to remove paint rather than rust.

i'm sure it is glass beads i used but i think it might be too coarse, when working was good but wasn't constant so might try the fine grade

I made mine from ply. 6ft long 4ft high and 4 ft deep so i can get bonnets and wheel rims in. Lined the inside with 10mm rubber to protect the ply. Them sat that on my pressure pot.

I have had a Model 970 Detailer for over 20 years and have been very happy with the unit...

Good company and excellent product. I have a 5 HP Cambell Hausfield compresser that rates at 19 CFM @ 100 PSI. Air compressor tank size is not as important as the ability for the compressor its self to keep up. That is where Cubic Feet Per Minute comes into account. Dandy Dave!

We use about the same model at school.

Works well but give a lot of dust by the doors. Even with a dust cleaner.
Paint is easy to remove. Rust is a bit harder. Normal grit is cheap. Glass is 4 time expensive, but give a great surface.
Price is about 650 euro's

The pressure pot is the expensive bit. The rest is a box with a sloped floor. Seal every joint. Plenty glass and light. If you use proper grit you wont need much extraction but if you use sand you wont be able to see a thing.

I've use a Low Silica Sand called Black Beauty for years. Cuts rust very well. Older paint also comes off well. Some of this newer Acylic paint is like rubber and is the hardest stuff I have ever seen to blast off. Even paint remover does not touch it. I usually use oven cleaner and high pressure wash parts first before blasting heavy castings that are full of grease and oil. The secret is to get loose stuff and anything the sand will just stick in off first. Dandy Dave!
