Do you have everything you need to start your project?

Here is a list and some helpful tips before blasting:

Shopping List:

1.  Air Compressor
Note:  I receive many questions regarding air compressor capacity for blasting.  It really depends on how patient you are.  You can hold the blasting gun trigger longer without loosing as much line pressure over time when you have a larger tank, which also means your air compressor pump doesn't need to cycle as much.  The procedure has been successfully carried out by pancake-style compressors with patience, however I recommend at least a 25 gallon compressor for your sanity.  Don't use in-line driers and/or oilers, they inhibit airflow.

2.  Shop Vacuum

3.  Blow Gun with wand - to insert into your vacuum adapter, blowing out excess walnut shells after blasting.

4.  Of course you will need the Bimmerhelp blasting kit for your BMW N20/N54/N55 or MINI N14/N18 unless you choose to use the OEM tools which are usually pricey and often back-ordered.

5.  Watts Barbed Fitting LFA-390 (or A-390) ***(see below)***

6.  Watts Bushing LFA-827 (or A-827) ***(see below)***

Note:  These 2 pipe fittings are required to adapt the Bimmerhelp wand to the Harbor Freight Portable Blaster gun.  Nipple LFA-741 (or A-741) is only needed when you elect to use OEM tools with the Harbor Freight setup, and must be modified.  Hex Nipple LFA-729 will also work, after modification, when using the OEM tools.***

***New Product for 2016!***
You can now purchase the Bimmerhelp Brass Fitting instead of 5 and 6 above!

7.  Fine walnut shell blasting media

8.  Portable Media Blaster

9.  Remote Starter Switch

10.  Masking Tape - for flagging connectors and taping over ports with "open" valves.
