What Our Clients Say
J B machining did some parts for me some specialty work. I’m a pretty good machinist and he was incredible. He’s one of the best machinist I have seen in my 45 years of working building parts and restoring motorcycles, extremely knowledgeable and reasonably priced very.

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”.

Good work…price came in at quoted price. Knowledgeable on different machine setups to get an abnormal/oversized job done.
Collin Neisen.
Very easy and nice to work with! He is also very knowledgeable about the work he does! Definitely recommend!
Kate Douglass.
JB Machine did an outstanding job for specialized test rigging I needed to hold test sensors to collect dust emissions. The rigging needs to be portable, light weight, highly configurable, and able to withstand off-road driving. Worked like a champ doing Army dust suppression testing and the results of the first test allowed us to save the Army over $1M before the test was even completed.
James Romano.
JB Machine & staff performed flawless machine work in manufacturing custom American Iron horse springier tubes for an American Suspension D-66 Dragon Suspension system. I needed 4 four foot tubes ordered and milled per sample, as the company representative from American Suspension was combative and wanted over $1800 to send me new tubes. JB hooked me up for an out the door price of $656.30; Perfect in every aspect. This business optimizes what Texas is all about; Pride, Integrity and a pure Get it Done attitude. Thanks.

Robert Torres.
Wife and I had moved to San Antonio TX recently. I had little information on the San Antonio JB Machine LLC. I decided to go there and met with the owner a great hearted, very professional and correct person. When he listened my problem he not only sympathized with me but also gave me a great price. I shall never forget his treatment which made me to call him a friend for life and use his machine shop even if I’d move to the other side of the world.
The spacer is done perfect . I highly recommend JB Machine LLC to anyone.
My review is outstanding for the business and great for the owner.

Corinne Hotchkiss.
I had the center bore increased from 90mm to 110mm to accommodate the hub on a full float posi rear end and JB Machine did an outstanding job as they fit perfectly on my 8-lug axles. Quality work at a fair price will have me returning to JB Machine for future custom machine work. Thanks JB Machine!!
Randy Contreras.
JB offers and comments on the limitations of a requested project but is committed to the smallest of jobs! TY for going the extra mile JB!
María López Howell.

FOR THOSE WHO ARE LEAVING NEGATIVE REVIEWS, I THINK THEY ARE MISUNDERSTANDING WHERE THEY ARE, OR WHAT THEY ARE EXPECTING. THE KIND FOLKS HERE, STRAIGHTFORWARD, ARE VERY CAPABLE OF COMPLETING PROJECTS, NOT ONLY CORRECTLY, BUT IN A TIMELY MANNER. MY ASK WAS SMALL COMPARED TO THE CALIBER OF PROJECTS AND PIECES I SAW IN THEIR SHOP, BUT THEY MADE ME FEEL LIKE A VALUED PRIORITY CUSTOMER. IN THESE DAYS WHEN MOST MACHINE SHOPS ARE BOARDED UP ON MY SIDE OF TOWN, JB IS A SHINING BEACON OF POSSIBILITY AND COMPETENCE, AS WELL AS KNOWLEDGE AND ABILITY. WILL DEFINITELY BE BACK WHEN I NEED MORE WORK. JUST WISH THEY WERE CLOSER. SO PEOPLE….IGNORE THE SOUR GRAPES REVIEWS HERE, JUST BITTER FOLKS.

Word of mouth is how I found JB Machine Shop.I am self employed and I know that service matters.I approached them with a rough general idea of what I wanted,he requested I draw it up to eliminate any confusion.When I did this it easily put us on the same page.With his insight of what I wanted he improved my idea .This reduced labor which in turn reduced cost.His prices are very fair .The more we got into my project the better it got because,I knew the end result I wanted and he ,with his experience knew how to take care of the project and the customer.

JB is a professional machinist to say the least. He is over the top helpful and knowledgeable. I have a unique convertible car and cannot get parts to maintain it. My top broke and needed a part. I went to JB and he understood my predicament and not only made the part but we put it in together! He didn’t have to but that shows his character and care he has in all of his work. HIGHLY RECOMMEND JB’s Machine shop!
