machine shop?

The machines are the smallest cost. Finding a bed mill is expensive you'll need that to do various block work. The tooling will be the biggest expense. One good cutter and you will need several is up to $1000 . A carbide end mill is $100 to $500. So tooling to do the work is over a couple hundred thousand. Torque plates for every block must be made or bought. $300-$700 each motor.

My son worked at a engine shop for years . He knew what machines to get to start off. He bought three machines new the rest he bought at sales and rebuilt them . Bridgeport mills are the only old mills you can get parts for easy. Make sure you have III phase electric. We are moving to a commercial property and getting III phase. Last month the electric bill using a phase converter was over $500. III phase hot tanks and block ovens take the most electric.

Make sure you have a good clientele and reputation . You'll get more work by word of mouth from satisfied happy customers.

Good young machinists are hard to find. He hired some and fired all of them. One guy was surfing the net on the phone while running a lathe.
