I am amazed at the equipment some of the big shops have. A vertical mill is probably the way to go. I am checking out another option also. There are machines made to machine pipe flanges that clamp on and are portable. There is a company in Calgary that specializes in this. I am just not sure yet what the accuracy is yet. It is nice that I live only 3 hr from a big oil town that caters to the oil industry. You can tell that oil is low, and the shops are slower. I ordered the ring on a Friday and it was ready Monday.<br>

Today I<br>
officially took the plunge and removed the forward ballast<br>
tank to install my new bow dome. After much agony I<br>
decided to make the change. I am not enjoying the sub<br>
because the forward window arrangement is not ideal for<br>
lakes with marginal visibility. I went to the big city<br>
yesterday and picked up the reinforcing ring and should have<br>
it fitted in a couple of days. I am bringing in a pressure<br>
welder to weld the ring and then the sub is off to the big<br>
city to machine the ring.<br>
