A couple months back I sent Bryon an email to see if he'd be interested in helping me with my small…read morefishing lure business. The job was small and fairly inexpensive so most shops wouldn't give me the time of day. Bryon at DB was the complete opposite. He setup a meeting to discuss my needs and within a week I had the parts I needed. I have since used DB for more projects and the work is grade A. I am very thankful for Bryon giving me a chance and helping me with this adventure. If you need a part made or tool made to make parts I highly recommend talking to Bryon and Anisa at DB.

It was my first time going to a machine shop to get a Volkswagen AWM 1.8T cylinder head decked…read more Luckily, Rik there helped me out. I didn't know you had to remove a lot of components and pretty much get to the bare head. Well, with his experience, he was able to close the valves and get a good clamp on it so he could get a clean cut on the head. He called me back in a couple of hours once it was done. From the decking process, lots of aluminum material gets into the nooks and crannies. I had to use an air compressor to remove most of the loose aluminum. I was able to install the cylinder head and now that car is running with no issues with leaking from the head gasket. Excellent work and a great price! I'd go back for more work to be done.

Customer beware!! I reached out to Ace Machine by phone to get an idea about services, costs and…read moretiming. Jerry at Ace Machine was very polite and let me know that he was backed up about 1.5-2 months and would likely start after the 2022 holidays. I agreed and dropped off my 4.8 engine. What happened next is infuriating. In early to mid January I called Jerry to see where he was on my engine and I got the same story, still backed up with other projects etc etc, a few weeks later, same thing. When I called back in March, I got a snarky Jerry who said, you can come get your engine if you want so I did. My engine was wrapped up when I dropped it off, Jerry unwrapped it and took a look at it so he know very well what he was getting. When I picked the engine up, the engine was wrapped just like when I dropped it off but I made the mistake of trusting him, what I got back was a piece of crap engine block that he clearly swapped out. Shame on me for not checking.

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
