The guys at JB Machine bailed us out in a big way. The pump in our shear failed leaving us without the capabilities to cut sheet metal during while our work load was absolute chaos. A replacement pump from the manufacturer was two weeks out which wasn’t an option for us. The guys at JB Machine sourced a US made pump and retro fitted it to our shear, which took them working a wwekend to take care of the necessary modifications. They stayed true to their quote, provided updates without asking and had the shear operational in a matter of days. In all honesty the shear runs better now than when it was brand new!

JB Machine shop pulled us out of hole on a part that we could not acquire through the manufacture of the equipment needing the part. JB Machine shop was our way out, they took the part we needed and reproduced the part without flaw.
The price we very reasonable and the part fit like a glove. Also the turnaround time on the part was expedient.
Great service, I highly recommend and if we need any more parts reproduced , we have JB Machine shop as our “go to guys”.

Thank you very much for your help with my most recent development project. Your help with surface grinding and quick turnaround time (1 day) were outstanding. Given a tolerance range of 0.001”, you did a great job of manufacturing the two parts to both the upper and lower end of the specification. Thank you again, and I look forward to working with you in the future.

As a group of four mechanical engineering students at UTSA, our graduation was contingent on delivering a built and tested prototype for our senior design project. We were partnering with a commercial sponsor that had very specific financial needs, and we couldn’t find any shop to do the job on time and at the price we needed. After we found JB Machine, we knew we had nothing to worry about!

There is no parallel when it comes to the upfront and continuous communication we got from these gentlemen, and they worked with us to meet our rigorous deadlines. We couldn’t be more satisfied with the finished product, and couldn’t have made it without the hard work and support of JB Machine!

The guys over at JB not only provided quick estimates, an honest timetable, and professional courtesy, but also quality work that exceeds their fair pricing. I recommend them for anyone’s next project

I had an odd project that I needed to get done. I needed two custom made molds for pouring lead. These molds were unique and had complicated dimensions. I went to four machine shops and was turned away. JB machine shop took on my project and produced the most flawless aluminum molds I have ever seen. Very satisfied. I will continue to do business with him.

Thanks JB Machine for doing a fantastic job on my custom hub rings for my 350Z. They fit like a glove and I couldn’t be happier with the new look of my car. Your professionalism, customer service and attention to detail are second to none.

Great product and outstanding quality. I recommend JB-machime anytime to take care of your special projects!

I wanted to thank JB Machine for the great job they just completed for me. The mill work they did so I could custom fit a wheel to my Harley was incredible. The application looks just like stock work. The milling was smooth, and I had a hard time finding any tool marks in any of the new surface. The sprocket fits cleanly in place and has zero wobble to it. Likewise on the spacer cuts. Each one was smooth, no deformation on the tubes, and free from burrs and nicks. No tool marks I could see.

I appreciated how they listened to what I was trying to achieve, and then suggested a plan. That was very helpful. This is the second excellent job they have done for me. I’ll be sure to tell my friends to contact them when they need a professional job done. Feel free to use me as a reference for anyone seeking to confirm their ability.

We are a General Contractor specializing in restoration of historic buildings. Many times we have to replace building components that have not been manufactured for decades, or have to come up with an off-the-cuff design solution to bring an Architect’s concept into reality. I was recently challenged with designing custom glazing standoffs that would suspend sheets of glass from framing supports. We turned to JB Machine for this challenge and found them to be diverse in ability, expeditious, and fair on pricing. Our company will enjoy maintaining a competitive edge and timely delivery to our client with JB Machine as a reliable source for custom fabricated components on demand

I was afraid that my job would be too small to bother with but JB Machine surprised me by agreeing to do it, and did so on time at the right price. If you have a small job, or maybe even a big one, check them out

I have to say Kudo’s to JB Machine for a job well done! I talked to them over the phone about an old part I had for a 40 year old Land Cruiser and some work I needed done after a heavy handed mechanic had broken off 6, 8mm hardened studs off below the surface of the part. I asked JB Machine if they could drill out the stud’s and replace them at the last minute for a trip to the beach I had scheduled. I only had a couple days and They dropped everything and made it happen. Without JB Machine I would have missed my trip. Thanks again and a job well done!”

JB Machine has given valuable technical advice, clarified fuzzy specifications and generally accelerated development on my open source Flexible Manufacturing System design at every turn. -Strongly recommended!

JB Machine is one of the most proficient machine shops in San Antonio, high quality work and easy to work with. The service is outstanding, I couldn’t ask for better quality. Great communication and always able to solve any problem that arises.

I purchased an antique windmill for my property in the Texas Hill Country. As is frequently the case, parts are missing and many are just rusted beyond repair. I had JB Machine build a set of oil bearing bronze bushings to replace the original Hyatt bearings that had been completely ruined from water damage. JB used the old bearings and the cast iron head castings to measure and build a perfectly matched set up bronze bushings. Their work was first class, timely and done at a reasonable price. I would recommend them without hesitation for anyone needing customized one-off part machining or production work. Good folks to work with.

I restore antique furniture, and recently, a client presented me with a bed frame with some of the strangest bed bolts I have ever seen. Two were missing and the repair work could not be completed without the two bolts. After failure with numerous suppliers and three other machine shops, I found JB Machine. They made two perfect reproductions in a very reasonable amount of time and within a reasonable budget. Next time, JB Machine will be my first call, not my last
Ivan Hentschel

Great business, outstanding work. I had a small one off car project that needed some custom work. I approached JB machine to help me fabricate some adapter fittings for some automovite fuel lines and they came out beautifully. He produced exactly what I was looking for. Next project I have I will definitely go back.

I have used JB to build some repair machine parts for my Cincinnati Centerless grinder and create some jigs for tool setup. Very helpful and knowledgeable. J. Quance-Fitch Drake Research Ltd.

We worked with JB Machine remotely (I am in MA) to help design and machine components for our fly fishing reel manufacturing. JB Machine was patient (this was the first outsourced machining work we’ve done) and helped make the parts much better than our original design. The parts are high quality and even though we made a mistake in the final design, JB Machine re-worked that parts without question. We are working with JB Machine for additional components.
Michael H

Our company rebuilds 20-30 year old plastics molding machines and we often have to reverse engineer parts that are no longer available. JB Machine is an excellent shop for our “one-off” parts. They are fast,reliable, and great to work with. They listen to our needs and get it done right the first time. We highly recommend their services and will continue to use their expertise in the future.
