Restored Rockwell Unisaw

The completed restoration of my 1977 Rockwell International 34-461 Unisaw

Over the course of two months I completely disassembled, cleaned, primed, painted, and replaced the bearings of a 1977 Rockwell Unisaw bringing it back to a like new condition.

Below you can see the restored Unisaw in all of it’s glory ready for another 30 years of service. Before pictures can be seen here.

Polishing Knobs For Unisaw

My process for polishing the locking knobs for my Rockwell Unisaw restoration.

Tonight I started polished one of the Unisaw’s three locking knobs. I used a 6″ 1/2 hp buffer equipped with a Spiral sewn buffing wheel and a Loose Cotton buffing wheel.

The buffing process is simple. Use a Brown polishing compound on the Spiral Sewn buffing wheel to get the initial clean buffed look. Then follow up with the softer Loose Cotton buffing wheel with the smoother Dark Gray polishing compound. I spent about 10 minutes polishing this knob between the two wheels and compounds.

I a very please with the results.

Priming and Painting the Rockwell Unisaw

When deciding on what I wanted the finish of my Unisaw to be it was evident that a perfectly smooth factor like finish was not going to be worth the effort. Multiple layers of paint would be needed along with sanding using 300-600 grit sand paper to smooth out imperfections that had been incurred in this saw 37 years of life.

To avoid the frustration that my perfectionism would bring to trying to achieve such a finish I decided to go for a textured look. I wanted what some people call an orange peel look or eggshell. While there are paints like Rustoleum’s “Hammered” product that claim to deliver such a look, I was displeased with their results.

After testing many products and application methods, I landed on using a technique I read about on where you under-power an HVLP sprayer to create texture. The overall paint process to create the texture and have a finished surface was simple. First spray your “texture” layer of primer. Followed by a layer of primer applied evenly over the entire surface (no this does not neutralize your texture). Then apply your final layer(s) of paint for color.

Creating a textured surface with Rustoleum primer

Creating the textured primer layer is simple but time consuming. Choose a thick primer product, I chose Rustoleum’s primer which I believe is an enamel. Then, without thinning the primer, spray the primer through an HVLP gun at a low enough pressure to create splatter. To achieve the specific texture I wanted I ran my HVLP gun at 22 PSI. Locking in the texture you desire will will take a bit of tweaking and playing around with your spray gun, but once it is setup it is incredible easy to get a consistent texture. The one downside, and this may be gun specific, is that this application method is VERY slow due to the low pressure of the gun.

Restoring a 1977 Rockwell (Delta) 34-461 Unisaw

My journey restoring a 1977 Rockwell International (Delta) 34-461 Unisaw


Early in January I stumbled upon a great deal on a Rockwell International (Delta) Unisaw from the 70’s on Craigslist. Knowing that a Unisaw is a timeless classic table saw, its age of 37 years old did not matter. All it meant was a little elbow grease was going to be needed to have the table saw running like it did when it left the factory.

Thanks to the good folks at and, I was able to identify that the Unisaw was built in 1977 in Tupelo, MS plus learn a ton of other information that is proving to be critical to the restoration process. and are both essential resources for tool restoration. The depth and breadth of knowledge available is amazing!

Game plan

My game plan is to completely disassemble, clean, paint, and rebuild the saw in preparation for another 30 years of service. I am also replacing the arbor bearings and will likely replace the motor bearings too.
