Built by Steen Cannons & Ordnance Works of Ashland, KY, (http://steencannons.com/) this is the test firing of a model 1841 field gun cannon. Riggs Machine milled and turned the cannon from a raw casting. This particular model is made out of cast iron. Steen did a beautiful job with the final assembly.
Here is the unit out of the horizontal mill after getting the trunnions machined. It is ready for the CNC lathe.
It’s been very exciting working with Steen. They do excellent work and we hope to continue our relationship with them. We never know what type of jobs will hit the shop, but these cannons have been some of our favorites!

These temporary cone and basket strainers (the models with the flat bottoms) are impressive. Used during start-ups and repairs, they will protect pumps, piping and other parts of the system from nuts, bolts and other stray debris.
Various Styles of Temporary Strainers
These are made of 304 stainless steel and custom designed. Riggs Machine can provide them in a variety of materials, styles and sizes.

They might seem extreme, but when you realize what they can save, they are worth every dollar!

There are several solutions to protecting workers and areas vulnerable to hazards like pedestrian and industrial traffic.
Some companies throw out a few cones, maybe even adding a flag or two for visibility. Then there’s the flimsy plastic folding barriers you might have seen around an out-of-service restroom at the mall.
But these solutions are not suitable for industrial environments. They don’t offer any real protection. They’re just one step up from wishful thinking.
Riggs Machine would like to suggest a better solution: the Mobile Safety Barrier.
This item protects the area around workers while in underground accesses such as manholes and maintenance openings or above ground on ladders.
Highly Visible – can be see by those walking around the area and in vehicles and forklifts.
Due to its sturdy design, it will not fold or buckle in high winds or bad weather. Can be bumped and still remain in position. It’s solid metal frame can withstand the harsh plant environment. Unlike plastic units, it can be painted any color or modified if necessary.
The Mobile Safety Barrier positions easily on heavy duty casters and can be loaded on a flatbed for quick offsite setup.
This convenient, sturdy, mobile, highly visible unit increases safety in your facility.

When a valve handle is not readily accessible, or the distance for proper operation is too great, a Handwheel Extension might be the solution.
Once affixed to the existing valve, workers have quick, ready and safe access to the controls when need arises.
Shown above, an inaccessible gate valve is below a platform. With a bolt-on Handwheel Extension, a worker on top of the platform now has convenient, safe access within reach and can operate the valve freely (without the need of ladders or rigging).
Also, by increasing the diameter of the handle on the Handwheel Extension, the valve may be easier to operate than it may have been with its original smaller handle.
These Handwheel Extensions are custom designed based on the valve size and distance from the valve to the operator’s control location.
Handwheel Extensions are often galvanized to help withstand the weather, elements and possible corrosion from chemicals in the facility.
If you have inaccessible valves that require outside rigging to operate or controls that put your employees in dangerous situations, call Riggs for an overview of the benefits that Handwheel Extensions can offer.

They say “wheels make the world go round”, but without shafts, nothing would ever move.
3D Render of Shaft
A shaft connects a mechanical power source to gears, wheels, turbines, rotors and much more. Shafts can be as simple a basic round bar or as complex as containing exacting bearing fits, keyways, sleeves, grease fittings, snap ring grooves and splines.
Broken Shaft – Removed from Assembly
Often, the shafts we see have been in service for many years, sometimes running non-stop. Unfortunately when these older shafts break (as shown here), there aren’t drawings available and not a lot of time to get the new shaft machined and the unit running again.
Half a Shaft – Part AHalf a Shaft – Part B
This shaft broke and we got it in 2 sections, still in the housing. After disassembly, we made hand sketches. While the housing was cleaned and checked, we created 3D drawings and then machined a new shaft.

Here is the new shaft ready for inspection. After passing final inspection, the housing was reassembled and the unit was ready for production use.

Hopefully a broken shaft won’t take one of your machines, or worse, your facility down. But if it does, Riggs Machine has the experience to get you running again.

There’s a reason for the fabricating in Riggs Machine & Fabricating. Here’s a perfect example. A client has an older machinery pedestal in very poor condition and needs a new assembly. There are, of course, no design drawings for the item, but luckily we can bring it to our shop.
Pedestal – Old Unit – Front
Pedestal – Old Unit – Side
First we make hand sketches of the unit. We review the original design to see if there were any structural defects that should be improved or any new features that the client would like to have implemented in the current design.
Pedestal – Hand DWG
Pedestal – CAD DWG
Pedestal – 3D Model
Next, these sketches are converted to CAD drawings and then 3D models are created for fit-up and testing. It’s much faster (and cheaper) to test a new design in 3D than it is after cutting 1/2” thick plates. When we are satisfied with the design, the files are sent out to have plates cut.
Pedestal – Pallet of Parts
This is what we get back from the waterjet cutters (Swift Manufacturing), nice pallet of loose parts. Now fabrication begins. If the designers did their work properly, the welders job should go smoothly.

And here we have the final assembly. From hand sketches to CAD to 3D models to cut parts to fabrication in less time than it takes some companies to return your call.

Industrial platforms and walkways typically use one of two types of handrail – round bar or angle.
round rail platform
updated angle based handrail
But recently we’ve seen the addition of a lower handrail, which is more ergonomic and comfortable.
smoother, more ergonomic grip
This additional handrail makes transversing stairs much safer. There are no breaks or pinch points as you move your hand along the rail. The placement is more convenient and it just has a better feel to it.
stairs w/ lower handrail
new handrail in place
Even better, this handrail can be added to existing walkways and platforms. If you have a heavily trafficked area or a thoroughfare on which you’d like to beef up the safety – rather than replace the entire structure, consider this simple (and cost effective) addition. Give Riggs a call, we’re here to help.

If you ever wondered where the custom training equipment in industrial classrooms come from, then look no further than Riggs Machine.
At Riggs we can create custom pieces from scratch, like this “oil flinger” demonstration unit. Shown from conception, with 3D renders, to the final unit in the classroom.
3D Oil Render Test

And we also often disassemble, create “cut-away” sections, sandblast, paint and reassemble actual pieces of equipment to be used in working classrooms. These units are used for hands-on training before students hit the field. Much better than a video or book based lecture.

Custom Cut-Aways
Some of these jobs can be more time and labor intensive than actual repairs! But we don’t mind. We’re proud to be part of the team who help educate the next generation who will be keeping our refineries, steel mills and factories running.

Blinds, sometimes known as blanks, isolate a section of pipe for repair, maintenance or testing. There are many types of blinds as we have shown before from the slip blind, the spectacle blind to the bleeder blind.
Here we have a nice assortment of Target Blinds. Used much like the bleeder blind, the target blind is placed on the end of a pipe section rather than in the center of a section. Gauges can be placed on the valves to test the pressure in the section of piping. Sampling can also be taken from the valve if desired.
The different sizes correspond with the different sizes of piping found within the refinery.
This group of target blinds is a bit “beefier” than usual. They will be used during the permanent shutdown of a unit until the demolition of the unit occurs. There may be need for occasional venting of the piping section until the demo.
