[Jim Bruton]

Hi Vet,

Let Ed and me know what the cost is as per Von Writter's query...

Thanks!

Jim

Jeff,
You've got me wondering now...

You building an air force over there?

Count me in for one. Flat kit is good. Pre-bents will be how much more?

Bent and welded will be an additional $50. You will still have to finish drill the holes, paint and make the wood handles.

Vet,
Count me in for one flat kit.
Thanks,

Vet,
Thanks for the pricing. 1 kit flat and 1 welded for 2 total.

Hi Vet:

Did you get the Quote with Nitrogen or oxygen assist cutting?

Thanks everyone for the interest. Right now I have requests for a total of 18 quadrants. I'll wait till Thursday to see if anyone else wants one, then order the materials. I'm aiming for delivery about the end of the month.

Laserloyd, The quote I have is for either waterjet, or laser. Not sure what kind of laser the company has. They specialize in steel rule dies. Is there a difference in cut quality and material integrity, Nitrogen vs Oxygen?

The kits will go for $110 each.

This includes all the parts laser cut with holes 1/8 inch diameter. The Mixture Plackard will be engraved, and the grooves will be machined in the Mixture backplate. Parts will need to be bent and the holes drilled to final size. Also the mounting bracket, and a few other parts need to be welded. Your responsible for hardware and wood handles. There will be some drawings included too. Material is 4130 steel.

PM me if you want to commit.

Hi
I shall take one as well.
Can you count me in?

Hi Vet:

Is there a difference in cut quality and material integrity, Nitrogen vs Oxygen?

All lasers are capable of cutting with different assist gases. Basically, Oxygen can be used for mild steel and Nitrogen is used mainly on stainless steel but it can also be used on gage mild steel to produce what we call a clean cut. This clean cut is a non-oxidized process that the oxygen would produce. You would be able to paint the nitrogen cuts with out any further process. The Oxygen cut will produce a oxidation on the edge that is like a thin skin and if you paint over it the paint will not adhere to the metal and flack off the edges. This oxidation then has to be removed. Most will take the edges over a sanding wheel to remove it.

Now, here is the catch, the Oxygen cut will be cheaper then the Nitrogen cutting because of the gas pressers used between the two. The Oxygen cutting uses low presser to cut, between 0.5 bar-6.0 bar (1 bar = 14.5 PSI) the thicker the material the less gas it needs. The Nitrogen uses high presser to cut, between 6 bar-20 bar.

Example:
4000 watts laser system
16 gage mid-steel (0.060" or 1.5mm)

Nitrogen gas presser = 10 bar
Nozzle size = 1.8 mm

Oxygen gas presser = 4 bar
Nozzle size = 0.8 mm

This shows the difference in gas volume needed for each gas, more gas = more expedience. You have to figure out if it's cheaper to use Nitrogen with out a second handling process or using Oxygen that is a cheaper process and be able to exurb the handling cost for the secondary handling process.

OK, too much info... So here is what I would do. Use the Oxygen cutting process then sand them your self, it's your time thats not under a labor cost constraints.
