I have some balls from a GT250 if they are all the same size ? I upgraded to roller bearings and for some reason I put all the balls in a little tray in my Garage and I know they are still there. Still greasy too I'm sure. The bike only had 8000 miles on it, so I guess they are okay. If you email me your address I can send you a few for free. I'm in Canada so I'm not sure how long the mail would take to get to you.

Bead blasting setup - whats needed?
Hey guys
Im sick of shelling out stupid amounts of money whenever I need something small blasted.
Whats needed to do this yourself?
I can get a cabinet for around $200AU, glass media 20kg for about $65AU
Already got a compressor...
How are the beads fed?
Do I need to buy a hopper of something too?
Any advice appreciated!

Ash,
LOTS of duct tape to seal up your cabinet (around the door, around the sight glass, etc...). The beads get EVERYWHERE!!! In fact, if you can blast with your cabinet outdoors, do so. Keep your compressor in a different area to keep beads out of it. Run a good high capacity water trap at the compressor and a smaller trap at the connect at the cabinet - if you get moisture in the beads they clump and you are through for the day. Connect a pressure regulator at the cabinet as well. Start with a practice part to get the pressure setting right. Too soft and the beads won't do anything. Too hard and you might as well be blasting with sand. 70-90 PSI at the cabinet usually gives me decent results on case sides. Also, don't blast any part with glass beads that has small oil passages that a bead can get trapped in. Invariably you will miss one and that's the end of that fresh rebuild. For crank cases and case sides with small passages, use walnut shells or soft plastic media instead.
A good comfo/dust mask/respirator with the screw on canisters is needed. Goggles are also a good idea. Clothes you don't mind ruining if you hit them with beads are also a good idea.
Good luck!

Ash,
Go here and download the product manual - the blast nozzle and the pick-up tube are sealed inside the cabinet. You load up the bottom of the cabinet with media. It's drawn through the pick-up tube, shot out the nozzle, past the parts, down into the "sump", and then into the pick-up tube again.

my cheapy cabinet had an emgo style filter in the upper rear corner to relieve air pressure in the box. i fit a collar and attached a length of hose from a junk shop vac. this hose is inserted into the bottom of a 20l. pail half full of water.
on the top of the 20l. pail i inserted the hose from my shop vac. turning on the vacuum draws the cabinet air though the water and then the vacuum. this keep the dust down in the cabinet and the shop. a pic is available if my description is lacking.
another thing to consider is the size of the cabinet. small is cheap but too small is a waste. i had to extend my cabinet by six inches to make it usable. i.e. a whole rim fits so the hub and spokes can be cleaned.

I would really like to get a blasting set up as well. What size /rating compressors have you guys had success with? Most of the technical data on the blasting guns require 5-8cfm @ 80-100 psi. It takes an awfully large/powerful compressor to handle those requirements. I have read that there are smaller nozzles available that you can use at lower levels. Does it just take longer with a smaller compressor? Thanks for the info.

Bead Blasting
Seconds on using a shop vac hooked up to keep the dust in the cabinet down, and to keep it from leaking. I did not hook mine up to the bottom to collect the blast media. Just hook it up to the side to keep the dust down. Let gravity collect the rest in the bottom. As an aside, if you keep the blast media outside the cabinet with the draw tube fed through, the vacuum in the cabinet will keep the media flowing a little better due to the pressure differential.
Also second the large tank capacity and stopping. You need to see what you've done, and what you still need to do anyway.
Finally, don't spend too much money on a big kit will all the fun bits. A sheet of 3/4" plywood, a sheet of plexi for the window, some duct tape (real aluminum tape, not the cloth stuff) and a set of gloves are all you need. I bouhg the gun form Sears for about $15 and built the rest from scrap ply. I have glove-box gloves from work, so I would say my total cost was only $30 or so.

When it came time to bead blast the paint off my frame, I was unable to find anyone local that had a blasting cabinet that would accommodate the frame. I did not want to invest a lot of money in a blasting setup that would be rarely used. So, I improvised, I already had a small compressor, I went to the local auto supply store and for a $120.00 I was able to pick up a small gun, blasting gloves and hood, 50 lbs of glass beads, duct tape and a tarp. I turned my 5X8 cargo trailer into a bead blasting cabinet, it was lined with the tarp, sealed with duct tape and away I went. It worked great, the only problem was I could have used a bigger compressor, but it got the job done.
Of course a few of the beads escaped out the back door and the trailer was cleaned out afterwards with leaf blower!

Hi Tom
Fasinating
I have just purchased a home with 165square meters ( 1800sq feet)of basment, so now I have room for a proper workshop for all my bikes, parts ,tools etc.
Now I have the space I would be keen to give this a go.
Can you keep the plating solution indefinately or do you need to make a fresh brew each time
Cheers
John
