Sand blasting has been covered in some other threads. Yes feasible for small areas but a portable compressor will lose loads of pressure across the regulator its just too small for big flows (just watch the pressure needle when you press the trigger), but you can just turn it right up and bypass it as a bodge, basic quick connectors are a bit of a restriction too. I used a 1" regulator in the end and some extra storage.

I worked under the car with sheets taped around the rear suspension area, the main problem I had was the nice face mask I used also got blasted, and with sand in places I didn't know I had! That and the 10mm hose I used also was a bit of an unflexible python. In the end I had to depanel and rebuild all the spring mounting points by cutting out the box sections.

Cheers.

That's why I am going to bridge two compressors mate. Dunno the CFM on them, but double may be enough. When I used the spot blast gun in the past it sort of worked, and hopefully with twice the air available it should be twice as effective.

It is only for small sections anyway, so fingers crossed it is up to the job.

I know I said I don't wanna cut corners, but fuck drilling out spot welds and removing panels. After that, where does it end? To do it 'right' you would need to remove everything until it was back to the original body panels! That's not one for me!

Nice to see this is still moving on man.
Those new wheels are the male dogs tesicle balls. i.e that means good.

Cheers mate. I hope they look as good as in my head lol. I need a Photoshop doing.

Got your new boots yet? Sorted the nut situation too?

I bailed on them. To futher fund new vehicle purchase.

I'll textualise you.

I tried 2 regulators, didn't really work either, still huge drops (30 psi). compressor CFM doesn't matter, usless marketing bollocks, a mains compressor will always have to rest and recharge. Althought the more CFM the less you kill the compressor. Look for the most watts and 150psi units. You have to bolt a 2l engine to it or something!

Anyway, yes 'where does it all end' thats where I am !!! rebuilding fekkin everthing.

There are certain areas of the car where de-panelling is pretty much the only option for a long-term fix.

cheers

CFM does matter but the flow rate which is important is the actual flow rate under pressure (ACFM). But for some reason (marketing reasons) most manufacturers only tell the ICFM value (Inlet CFM) which doesn't tell anything about the real flow rate at the pressure side when operating tools.

Basically for media blasting jobs you want to get as large compressor with as much power as the wallet and the fusings of the building (if the compressor is an electrical one) permit.

At the garage we've got a 5,5kW 400VAC compressor with a 200l (44 UK gallons) tank and the manufacturer announced inlet flow rate is 900l/min (32,5 CFM). (More powerfull one would've required larger main fusings) It's good for occasional non-professional sand blasting with a suction type media blasting gun (type which doesn't have a tank for the media, it just sucks the media used through a pipe). A sandblast tank would be better though than the suction gun.

Professional media blasting shops usually use a combustion engine powered container-size compressors or electrical screw compressors which have dozens of kilowatts of power and actual flow ratings measured in cubic meters.

Thanks for the insight Fuse! That makes a lot of sense.

I have decided against using the compressor though. All sorted now.

Shitty update; More painting, more welding, more seam sealing. (basically that for the past few weeks)

I am still at the stage where I am removing parts instead of refitting them too. Whipped the front screen, quarter glass and car side of the blower assembly out tonight. Stuff ends up getting in the way and (ime) jobs take you longer when you are working around things. Like covering the screen so it doesn't get pitted from welding and grinding.

Happy to say that the screen surround is in A1 condition. I had my doubts.


Have a rcouple of random pics

Beans maybe (fridge cold ftw ). Nee onions though!

Your plan would replicate the exhaust to an acceptable standard, need a bottle of pop or something for proper bo BOV sounds though!

Looks cracking work, I wish I had the space and money for a project car

Dont let that stop you dude. I dont think Liam had much of either when he started!
