has anyone got one besides the size limitations do they produce good enough results .im looking at getting one soon would like some feedback first
regards Dave

 

weve got one in our workshop, i,ve just used it to clean the bits off my engine (plenum, throttle body, engine mounts etc) they have come up mint, the sand roughs up the surface so when you paint it sticks like sh*t

 

yup one of the best things i bought,you need a good sized compressor tho

 

thanks guys thats what i wanted to know cheers another question then you say it roughs the surface up is it ok to do mating faces on my manifolds then or should the faces be masked up ?????????
thanks for any advice

 

mask em up fella gaffa tape is the dogs danglies for it thats what the pro s use

 

cheers guys the advice is appreciated

 

You can change the surface finish with different abrasive grit, for our blasting we use a 3hp 150ltr 14cfm which is plenty. We could not live without our cabinet, its one of those items you never get round to actually buying, but one you get you will be thinking, where have you been all my life.

Hope this helps

Thanks Raj

 

yeah must say a nice bench top or any cabinet the bigger the better really brings alloys etc back to life .go get one

 

Just out of interest, what pressure do you set the compressor at when shot blasting?

 

That all depends on the part you are blasting, media being used and the finish you are after.

A good all rounder is 90psi with 1"hose and 60-80 media

The bigger the volume of air being used the easier it is to control, I have a 1/4 " blaster at my unit which is very hard to control, at 130psi it is much less affective than my other 1" system at 90psi!!!

Hope this helps

 

partically stealling this thread here but what is best for just general use at home and projects, shot bead or sand blasting thanks

 

We use oxide 60-80 media for pretty much everything part I do and thats for powder coating. Everything we do is taken back further by hand though to give the best finish. This could be achieved by using glass beads or alternative media but in all honesty is too much of a ball ache cleaning the cabinet out each time. You need to consider what you are blasting and what finish you are after. Sorry this isnt much help, feel free to give me a shout on 07894 636 707 if you need any more help and I will do my best.
