The starting of the stripping process

[shipard]

i was thinking i getting a cheap sand blasting unit.......anybody had much experience with them ? i am looking to try and polish the hubs or possibly clean up a few items, remove some rust etc before painting them mat black. Open to suggestions from others who have had experience with them.

Not sure if you mean a blasting cabinet or portable blaster?
Anyhow I have both and they are a dead set winner, I had to experiment with things to get flow rates and pressures just right.

Hi Chris,

I was thinking of a portable one at this stage, ( I am aware of the cabinets as well ) but thought the cabinets might be a little restrictive as opposed to portable blaster. I have room so left over sand isnt a problem.

Was thinking something like the two below would work well. Chris are these similar to yours ?

actually looked a bit further and thought this cabinet would fit most parts and well priced

I have a pressure blaster and a small glass bead cabinet. I just bought one of these... http://www.stanblast.com/

How much Fishcop ?

Whats the actual blasting unit you use ??

[shipard]

Thanks for the link John, what size compressor did you use with this unit. Sorry the website doesn't really highlight the litre per minute free flow delivery.

Also did you go the powder coating route or just matt black for you parts like rear trailing arms etc.

Okay, here comes "Home Blasting 101"...

The $160 odd pressure blasters are by far the best for ripping into rust and corrosion - I use garnet. But they are super messy and blow the media over everything. It's fine if you have a big yard or an area you can sweep up later, but no good for a confined space. I run mine using a 15cfm twin piston compressor at about 90psi. Blasters use air up super fast, expect only bursts of about 10 seconds at full pressure. Constantly running the compressor to keep up will burn it out if you don't "rest" or duty cycle the compressor. This is the generic Chinese made unit I use https://www.tradetools.com/products/XHSB10

The small cabinet blaster has glass in it and it perfect for cleaning small alloy parts - it is a "detail blaster". It's great because it can be used in the garage with minimal dust as I have it rigged up to an air extractor (old vacuum cleaner )

I hope to rig up the Stanblast unit to work with my pressure pot blaster. Hopefully it will allow 'cabinet conditions' with high power garnet blasting and recovery of media for re-use. Shane Tan in Sydney sells the units - he is 'Shanet' on Typ901.org and recently advertised that he had a few seconds available for $200. But most people were too busy poo-pooing how cheap Shane sold me an early guard to pick up on the cabinets in his ad http://typ901.org/showthread.php?t=4580

Clayton I powder coated the front A arms and painted the rear trailing arms in 2k epoxy. Powder coating was part of a batch I was getting done. The rear trailing arms got restored later and by this time I'd become handy with my spray guns, 2k polyurethanes and epoxy, and matting pastes... No real rhyme or reason.

Thanks John, as always you're very generous with your wisdom and experience, I really appreciate it.

[Fishcop]

No problem Clayton. I'm just pleased that others are getting in there and having a go.

Hey John,

One quick question for you, with the electrical cords that run down through the tunnel of the car and out the rear, did you pull them towards the front ? and did you have to remove the plugs etc to get the cords through the tunnel ? I will post some pictures shortly. Basically I only have this electrical to remove, and then remove the glass from the doors and i have a shell to clean up.
