Car Forum / MINI / October 2003Buying some tooling
Just been to have a look at my shell and it is escalating into a full on shiny thing rebuild - if you are spending a shed load on the shell there is no point in bolting rusty things to it ;) Anyway, I was wondering about buying a sand blasting cabinet and there is one you can get for about 120 quid with hose and gun. Does the sand go into the gun or do you need something to go with it? Thanks a lot The Muffin Man > Just been to have a look at my shell and it is escalating into a full on > shiny thing rebuild - if you are spending a shed load on the shell there is [quoted text clipped - 7 lines] > > The Muffin Man The grit (sand is no longer legal to use, I understand) sits in the hopper at the bottom of the cabinet. Then there is a dip tube that the gun sucks the grit up through. When the grit is fired out it simply falls back into the hopper. I have to say, we struggled with one of the cheaper setups. And we had a very big compressor. The air consumption is quite high, so if you only have a small compressor, check the requirement carefully before you buy. You will also require plenty of the ceramic nozzles. They wear out at an alarming rate and the efficiency goes off very quickly. Another thing worth doing, is to buy some 2mm or 3mm sheet rubber and line the back and side walls of the cabinet. These budget units are quite thin walled, and you are grit blasting in them!!

Thanks for the advice Steve. The compressor is a friends so I will check with him how big it is but I know it aint small. The rubber is good advice, I was wondering how it didn't blast a hole in itself. I am not looking at blasting for a living with it merely components for one car - wiper motor bracket - radius arms and the like. Do you think a cheaper unit would do for that - if not, what would you recommend instead?

It ended up like a new one!!! Failing that, I think Machine Mart have the small blast cabinets.

It needs diluting with about 5 parts water to one part acid and it is excellent to drop brake drums and such like in. Far, far cheaper than the phosphoric acid dips from Halfords! SignatureChris Morriss Gents, here in oz we have a mob called endeavour foundation - they offer closed workshops for disabled people- anything that I need blasted or chromed - i take there - quite cheap and it supports a worthy cause.

Here in Australia, the farmers all keep a 44 gallon drum of molasses that is an amazing stripper and very cheap compared to proprietary strippers. Mate of mine uses it for stripping parts from old 2CV's he gets from Europe to restore.

Just had words with the man, Makka. Apparently it's cheap and effective for stripping metals of rust, paint and grundge but slow. It's a soak for a week or two deal. The material is standard mollasses used for stock feed. You dilute it 1:10 with water then sit back and wait.
