Default Bead Blast in MD

Hi Guys,

I am located in Damascus, MD

Would anyone allow me to pay for use of their bead blast equipment to clean up a bunch of hardware before I phosphate the same hardware.

I would be happy to contribute towards the purchase the blasting media or even provide the labor to bead blast any parts you may want done too.

Thanks,

What kind of hardware do you have? Maybe something like this would work. http://www.eastwood.com/18-lb-vibrat...and-media.html

I have a small siphon feed sand blaster that would work if you have an air compressor.

Hi Bill,
How many, and what parts, do you have.
Might you consider cleaning them with a wire wheel mounted to a variable speed bench grinder?
I used this method for all my parts because I was concerned that blasting might change the texture of the surface of the parts and bolts.
Regards,
Alan

Hi Alan,

I am seriously thinking of this option for the same reason.

How did the phosphate treatment work for you after just using a wire wheel. I know that you did a fabulous job on your 71.

I was thinking about using evapo-rust then wire wheel.

The hardware is in very nice shape as it spent most of its time in the desert of texas.

Thanks,


Bill

Hi Bill,
Both the phosphating and black oxide worked very well after using the wire wheel.
I found that the part needs to be very clean and then you shouldn't touch it without using tongs or latex gloved hands.
Here's a picture of both a phosphate and black oxide bolt.

Alan

I am sold Alan

Did you use a bench mounted grinder with wire wheel?

BTW: What is the head mark on your alternator ground bolt?

Thanks,


Bill

Looks like blued on top, and parked, er, phosphate, on the bottom...

I need a bigger house... with a grinder and room for a bunch of recoating buckets!

Hi Bill,
Yes, I have a Sears variable speed bench grinder that I bought back when I started all this. It's held up well.
I use wire wheels of varying coarseness.
I have the zinc and manganese phosphate materials from Palmetto Enterprises, and the black oxide kit from Caswell.
The phosphate is easy to do although the bath does need to be heated.(Stainless steel pan, hot plate, and thermometer). I then immerse the part in an oil based sealer.
The black oxide process is just immerse the part in the liquid, and then the sealer.
The shine on the black oxide bolt in the picture is from the oil bath. It soaks in and pretty much disappears in a day or two.
I still haven't gotten my zinc plating going yet, but hope to in about 6 weeks.
Regards,
Alan

Hi Bill,
The alt. ground bolt is an 'R' with 3 slashes..... it's the original.

Thank you Alan.

I am trying to see if there are any head marks besides the R. So far 100% of the original have been the R.

I am looking for the correct bolt and have a couple leads.

Bill

Tony has been a huge help. He has done a number of jobs for me that require specialized tools.

This is something I want to do so I can do it in small batches as I work through the chassis.

How many and what size parts are you talking about?

I'm in Ohio, but if it's just a few misc. bolts, brackets, etc. you could toss them in a flat rate box and send them to me. I'll blast them for you.

It is quite a few pieces of hardware. Basically all the hardware from disassembly of everything behind the engine including trans, rear, T arms, gas tank, bumpers, etc..

I am going to take Alan's advice and go out and purchase a bench grinder and wire wheel attachments. Most of what I have will be treated with zinc phosphate. I have Tony's corvette doing the few items that are zinc plated. He sent them out with a large batch he was having done on one of his own cars.

Thank you for the offer. I will definitely keep it in mind as I continue.


Bill
