I stopped in on a Saturday and needed help with a project. The owner stopped what he was doing and…read moreliterally fixed my problem. I had already stopped in to three other local shops and they all couldn't or wouldn't help me. Then on top of that the guy didn't even want to charge me. Of course I paid him for his time and thanked him for the great service. This is a full blown machine ship, they are very friendly and seem to really know what they are doing. If your looking for a machine shop stop looking because you found a great one right here in Costa Mesa.

They did a great job and the accuracy was there. If I was still doing that I'd go back for more. I went into metal fabrication myself with a full machine shop. Times and needs change, if China had not dumped chea kits on the market I'd still be doing it. Let's face it, R&D for R/C planes was fun.I enjoyed the work. This outfit made getting odd parts easy. I hope they are doing well.

Mark is the man! Called him up and he helped me bend some sheet metal on a Saturday afternoon, even…read morethough he doesn't usually work weekends. He knows his trade. Called a couple of other "bigger" shops before him, and they didn't know/ could do what I needed. Reasonably priced, accommodating, and down to business. Don't hesitate to give him a call! He's got you covered all things metal.

These guys are carving quick change differentials out of solid billet blocks of aluminum along with anything else you need I was blown away.

I decided to give Engine Supply a try after my previous engine developed a major oil consumption…read moreafter a rebuild. I have yet to disassemble and determine the cause on that engine. I needed some cylinder head refresh work done on a replacement engine and took my head here. It's for a bmw s54 engine. I understand Engine supply does a lot of domestic work but will also do European and Japanese engines. After speaking with one of the guys, I found out that it's a family owned and operated company. The guys are definitely knowledgeable. The cylinder was picked up and was in great clean condition as expected by a good machine shop. What impressed me was they took me to the back to show my cylinder head during assembly when I dropped off my valve seals. The shop is well organized and clean. When I picked up the cylinder head, the Machinist who worked on my cylinder head also mentioned that the valves were returned in the exact order it was removed, which makes putting the shims I removed back it the same order easier to adjust the valve clearance on assembly. The cylinder head was assembled back into the used block. And is now running in the car without any oil consumption. It has done multiple track days without issue. I'm very happy with their work and can vouch that you are getting top notch quality work. Thank you Engine Supply Team! -Clarence

Have used them in the past and although it came out higher than expected, they were transparent,…read morehonest and cordial. Fast forward to this instance where I have a batch of rotors that I needed to be turned down 1mm each side. Call him, describe what I'm needing and ask if he has a rough estimate on price. He asks me to text pictures, I jot down his number and then send him pictures shortly after. Gave him an hr or so and called him back to see if he received the pictures. Doesnt reallt acknowledge it and is pushy to have me bring them in and that he can do it. I'm about 25ish mins away, but he insists that he'll be late at the shop and that it's no problem. I bring in 1 rotor to see if he can still give me an estimate and he suggests he can help me bring in the rest of the rotors, about 10 in total. As we're bringing them in, I ask him again how much he's thinking it's going to be and he mentions $50 each. At this point, it's beyond the threshold in which the supplier was going to reimburse me for so I ask if I can just machine 2 rotors for now and figure out what can be done with the supplier. The next week rolls around and days go where I dont hear anything. I text him and no response for a day or 2. I call later the following week and he gives me a response like the rotors have been done and that he's been waiting on me. I ask him texting is the best method of communication since he originally asked me to text and he said text is good. I ask him if he's been receiving my texts in which he responds with affirmation. I go to pick up the rotors and come to find out that he only did a single rotor in which I ask when the other side would be done and he says in about 1-2 business days. I say that's fine and then mention that I'll leave that single rotor behind and grab the rest. He then mentions that if I in doing just 2 rotors, that the price would be $100 each. At this point, I'm no longer feeling like this is about money and get the impression that he's just a shady crook now trying to take advantage of people. I'm a little shocked at the pricing at this point and ended up just taking all the rotors back and paid him his $100 to machine a single rotor. Ended up having another shop do the for $20 each
