CNC cut signs, powder coating, TIG welding

Lots of projects on the go, everything from CNC cut signs, powder coating, TIG welding stainless steel/aluminum parts to MIG welding a 280# steel pipe rack.

Most projects we supply the material for the job at hand, however we also accept customer supplied material too.  Here we have some 2″ and 2.5″ SCH40 pipe dropped off and ready for processing.  We had a design submitted from the customer and it is now time to get to work!

We took the customer design, modeled it in Solidworks to get an idea of weight and to help with creating coping templates for the “v” section of tubing.

Pipe Rack

Most tubing can be coped with a hole saw in a tube/pipe notcher.  However with SCH40 material of this size coping it on the bandsaw is much quicker and more cost effective.  Notice the c-clamp at the bottom left of the photo.  This ensures a consistent cut location by allowing the tube to butt up against it prior to cutting.  Repeatability just makes things so much easier and quicker.

Here’s all the tubing processed (except for the “v” sections), the ends are cleaned down to raw material to ensure a good quality area to weld to.

And here’s the final product ready to head back to the client’s shop.  It will be used to drop in various pipe via forklift and then allow it to be easily banded and removed as a whole with a forklift.

Here we have a modern sign made for a local home builder cut out of 1/4″ steel.  This is after it is cut, acid bathed and media blasted.  It has some weight to it and is now ready for powder coating.  This is the first time we’ve powder coated a part that has been previously engraved.  Notice the engraving near the bottom of the part?

Here it is after having bonded silver vein powder applied to it.  And the engraving disappeared…

Powder looks really good and has a slight texture to it, which is why it filled in the engraving.

So here’s the solution.  Engraving and cutting a 16ga 304SS piece to be secured with the two bottom mounting holes.  Looks much better!

Here we’ve got a few 304SS pieces that need welding, a few alignment marks  from the customer and some tweaks are needed prior to welding.

No problem!  Everything stainless steel is backpurged to ensure that there is 100% penetration and to ensure that the inside of the weld is just as protected, strong and as beautiful as the outside weld.

Miscellaneous parts needing some last minute work prior to a car show coming up.  It’s not every day we can do same evening turnarounds…but in some cases we can make it happen.

All done welding.  100% backpurged as per usual.  The customer only wanted the first few inches of the tubing brushed as the rest will be covered up with ceramic exhaust wrapping insulator.

The intercooler had some brackets welded on as well as another SS dump pipe having a flange welded on.

Just some of the parts to pick up today before the Easter holiday!

Welding table top, exhaust and powder coating

We’re always working on a variety of projects so nothing is ever dull in the shop!  Here are some of the things that have been cut and built recently.

Here a customer designed a slotted welding table top which will allow for the use of clamps in various positions in and around the table.  It is 3/8″ thick hot rolled 44w steel.

Nothing but the best!  Our CNC table allows for high quality cutting with minimal dross.  It allows for very quick clean up time which eliminates extra cost.

Here we have a Subaru external wastegate (EWG) dump that will be merging back into the downpipe.  You can just slightly see the external wastegate dump to the right of the downpipe and just below the cross member.

After finishing the wastegate tubing and coping it to match up with the downpipe it is tacked in place to ensure the whole system can be removed from the car (it is very close to the front CV axle). subaru wastegate 

Now with it being removed the dump outlet is traced onto the downpipe, the tacks are broken and is ready for plasma cutting, brushing, final tacking on the car and then finish welding on the bench.

We also had a F20C (from a Honda S2000) valve cover getting ready for powdercoating.  It is washed, blasted and then pre-baked.  The pre-baking allows any oil in the grains of the aluminum casting to push out to the surface and be cleaned via another blasting process.  Not doing this step could result in oil coming out during the powder coating curing process, and if that happens powder coating defects will occur.  So cleanliness is very important.

It’s hard to see in this photo but there is actually a 4″x6″ rectangular tubing that fits just inside the valve cover to elevate it off the rack.  This doesn’t matter much for the pre-baking process, however during the powder coating curing process it is.  Nobody wants indentations along the bottom of their valve cover from a rack!

All threaded holes, nipples and open fittings are plugged with silicone plugs and masked with high heat tape.

The customer chosen wrinkle red powder is applied.  The powder coating equipment we use varies the charge voltage to the powder particles, so it avoids the faraday cage effect.  Essentially sharp corners or deep recesses will actually repel powder, so by changing the charge voltage differently charged particles will “stick” in different areas.  Thus allowing for a more consistent coverage and higher quality finish in the end.  Now it’s ready to go in the oven.

And here’s the final part after all the plugs and masking is removed.  Nothing but the best for our clients!
