[Shop-talk] compressor/sandblast guru question

[John Niolon]

thanks guys for all the info...  I guess my quest begins to find/build a blast
cabinet...  the shop is plumbed per tip tools diagram using 1/2" galvanized
pipe (yes, I know black is better but galvanized was free.)

The main run is about 25' long with 4 drops that come off the top of the
pipe... down to a fitting in a tee and a ball valve/drain at the end of each
drop...  water filter at head end about 5' from compressor and another at the
end.  Compressor makes about a cup of water a week with occasional use with
air tools and a da sander... I've never gotten the first drop of water out of
the system when opening the drains... but I did blow a lizzard across the yard
once.

can anyone recommend tip sizes ... if I build, I'll just buy the kit from TIP
I guess... but all info and recommendations are appreciated..

thanks
John
