My contact at A & J was Suki, who listened carefully as I explained the application and then made some recommendations about the thickness of material and quoted me a very fair price. When I picked up the piece, I was surprised to see the attention to detail on the finish. Although I had not asked for it, all of the edges had been rounded. When I mentioned to Suki how impressed I was and that I hadn't even asked him to do this (since I was on a budget and wanted to keep the cost down. I had planned to use tape along the edges.) he said that since he knew it was going in my kids room, he wanted to make sure there was no chance they would get injured. Outstanding work.

He crunched some numbers, found it it's cheaper for them to cut it for me vs me buying a bigger sheet and spending my own time cutting it to spec. They saved me hours of work for something that may not have turned out as nice as how they cut it. It took about 20 minutes and the gentleman was nice enough to walk out to the parking lot to find me and let me know. I parked in the back and they brought it out to my car. I changed the specs last minute and they accommodated that too. My buddy told me everyone here is helpful and nice and that's 100% the truth! Everyone here is so nice and polite it felt like I was at a resort. Companies like this will be around forever because of staff like this at Industrial Metal Supply.

Otherwise I had an issue with whoever I talked with over the phone that misquoted the price and wasted my trip.

I have been going to Jan and Deily for the past year and a half, for various company projects, as…read morewell as my side-projects for my house and cars. So it has been due time for me to write a review for him. Before I do, I have to say it is funny to read other reviews on Yelp, like the one about pressing car bushings (which truly not even specialized car shops would do). I have to go back to Jan for that, because I did not know he did such things. I had given up on replacing bushings on my car, after being turned down by so many local auto shops and mechanics. Now for that reviewer that rated them badly for a four week lead time... what sort of expectation was that? A poorly-run machine shop has downtime to let anyone cut in. By all means go to those shops instead or pay an arm and a leg, if that is the expectation... however, Optima Precision operates like all properly run, established machine shops do... schedule your work into their operation or work an expedite out with Jan and Deily... We are even lucky they are open to our side-projects. Bottom line, talk it out with them. They are very open to making things happen! Anyways, just to give a little background, I formerly worked as a design engineer for Zodiac Aerospace's oxygen system division, that made a lot of pneumatic components such as valves and manifolds. I can certainly attest that Jan and Optima Precision has the expertise and capabilities to machine top-notch quality parts. Whether you are dealing with extruded, cold-pressed, tempered aluminum, steel or etc., or softer brittle plastics like plexiglass or acrylic, up to something like 6 feet by 4 feet (double check with him), he and his crew can take care of that. I originally went to Optima Precision because Jan and Deily were the more responsive, local machine shop. They are very approachable and easy to communicate with (their English is solid). Most importantly, their pricing and lead times were very competitive, compared to the other shops in the area. Easiest way to describe them is that they are flexible and understanding like the old machinists but they operate with the newer CNC mills (even though they have Bridgeports off to the side). In other words, they are not like other new machinists that refuse small orders and cannot think other than what their CNC machine tells them they can or cannot do. What do I mean by an old machinist? Jan did not just go off my engineering drawings, but he verified my design intent to make sure my parts would fit and functioned well in my application. He was more concerned with what I wanted my part to turn out as, rather than what his machines could or could not do. To affirm other reviews, Jan and Deily are truly open to make small quantities (even one or two pieces like other reviews stated) and, of course, scaling to large production quantities. If you have worked with machine shops enough, you would understand that Optima Precision is a no brainer to have your parts, at least, quoted there each time. Long review, but hope that helps you all when considering!

I mentioned I was not in a hurry and could leave it for the weekend. Before I could finish explaining and before price was even discussed I was interrupted and told the wait would be 4 weeks.

I dropped the part off at another machine shop and had it back minutes later machined perfectly to specification.

I had issues with my CRV and it started making a weird noise that was coming from the wheel well. I took it to two different mechanics. One said it was the brakes. So I paid to have it changed but the noise was still there. The next mechanic said it was an alignment issue so...I paid to have THAT done and the noise was still there. Finally, I heard from a close friend that he knew a guy that could fix it. Took it to Winston and he diagnosed it to be a wheel barring issue. If I didn't get it fixed soon, then it would have caused more damage. Winston fixed it for a good price and the noise went away. Now, I take all my cars and he gets it fixed and at a fair price.
