Refinished my Sebenza

Wow, thanks for posting this!!!

My boss has one of these sitting over in the corner collecting dust!

I must try this out this weekend!!!!

I wonder if it would be strong enough to do ZDP-189...???

How close do you get with it when you are blasting and how long do you leave it on one spot?
 
I use mine about 6 inches away from whatever I'm blasting and just do it until you get a nice even finish with no imperfections showing. It really doesn't take long. I use glass media and it looks almost identical to the finish CRK uses.

A word of advice there Swmp4l: If you start seeing sparks flying off the titanium where the beads hit, don't freak out thats normal!

Also make sure that you tape all the sections you don't want blasted ie. the lockface and where the washers rest against the ti. I rub the surface down with rubbing alcohol to get it all nice and clean and then cut some duct tape down to size and tape the areas off. It will not blast through the tape or peel it off like it may seem.

Also I like to regulate the compressor to 90 psi when blasting, it seems to be a good happy medium. Have fun!
 
I have another question for those in the know. When blasting screws, do you only do the heads or the entire screw? I think doing the entire screw will mess with the spiral? How does CRK do theirs? I have only seen the bead blasted screws when they are already in the knife, not before they were installed.

Don't blast the threads ! Stick them into a piece of cardboard and only blast the heads of the screws

That is what I was thinking. I dont have a machine or anything but this info is good to know before one tries anything. Thanks for you help.

Ok. My final question I just thought of: When one blasts the Ti is one actually removing the Ti, or is it like a coat one puts on?


I found this definition but dont know if it can differ from other types of sandblasting: A surface treatment used to remove material by using air to blow sand or other grit at a workpiece.

If this is true then I can understand the need to use 'finer grain' sand or abrasive and lower pressure to minimise the amount of material taken of?

They use the term remove because it's used also for removing paint and rust from metal
 
If you would, please explain your set up. Safety equip., where you do your work, amount of mess, part prep, etc. The reason I ask is I have thrown around the idea of doing something like this several times. I have looked at several of the blast cabinets, but always thought they would be too big and I couldnt justify there space and cost for just a few projects. Also, all the ones I have looked at say NOT to use sand due to health risks. I think the projects you did look outstanding. I have several Sebenza clips that could use this traetment and I probably could find a few more knifes to experiment on!

ok my setup is very minimalistic to say the least lol but here it is!!

1. harbor freight portable abrasive blaster kit (50 lb hopper)
http://www.harborfreight.com/media/...eab33525d08d6e5fb8d27136e95/i/m/image_449.jpg

2. sakrete play sand from home depot (4 bucks for a 50 pound bag !)

3.saftey glasses

4. gloves

5. mask or resperator

i do it all out on the lawn so there is no mess to clean up after blasting is done . i also think if you use sand outside you don't need to worry about it being a health concern, its is just a warning because prolonged exposure (like a life time of sandblasting for a living) can cause silicosis ! i also use sand because blast media is rather expensive unless you are using a cabinet that is recycling it .
 
Yup Softrock pretty much covered it there if you don't have a blast cabinet. You don't really need one though unless you're going to be doing a ton of blasting. One thing I might add is to use a large cardboard box as ghetto blast cabinet. If you want to get real fancy you can even cut out a hole on each side for your arms to go in and then either a hole in the top open or lay a piece of plexi glass over the opening so you can see but the media doesn't blow back into your eyes. Make sure you use good eye protection and a respirator. Also with the cardboard box cabinet you can reuse the media that collects at the bottom.

All I used was a gravity fed gun with a small compressor and plain old sand!
