Any cheap kits worth buying. What about DIY I have seen a few videos on converting an air gun.
yes are you using a cabinet and a suction gun . if you are you will need to empty the cabinet for the different media if you changeCan you Bead Blast and Sand Blast using the same gear?
if you want polished on aluminium just get buffing with different grades of polish and using different grades of wet and dry abrasive before you start.
Johnny,
I have had success converting a long nozzle blow gun, file a V into the top of the nozzle, then put a hole through the neck of an empty pop bottle (below the cap and flange) slightly smaller than the nozzle diameter, push through the bottle, get the bottle vertical pointing down over the v and seal, then invert take off the cap, fill with soda, put the gap abck on and you have a gravity fed blast gun for £5.

It works with fine media, ( Soda/fine sand), the bigger you go with the media grain size the less effective it is, I think you will struggle with glass beads.Would this work with other media such as glass beads?
Did you go with the one I have used?Ok tried two version of a DIY blast gun both FAILED miserably :-(
Did you go with the one I have used?
What went wrong?
For soda blasting I use a cheapo spotblast gun from Aldi or Lidl. Don't bother with that collection bag thing That it comes with. as I have a reasonable space outside my workshop I just blasted this gearbox out in the open.

The bellhousing area wasn't blasted as I am going to machine off that part of the box so it can be mounted up to a different bellhousing. Mycompressor has two water traps in series, didn't seem to suffer any problems with clogging of the soda.
Very nice - Soda Blasting though - what a mess - where is all the Soda?
I tried the pop bottle method - press the trigger and get some soda out, release the trigger and half the bottle empties out :-(
Weird, didn't happen to me.
How bog a hole did you file in?
