How to trim the bulb?

[thomas]

I can't find any information in the builder`s blogs how to trim the lead bulbs. We have casted our bulbs (see my blog  minisailer.ch) and now need to trim them to the exact weight and plan them on the side where they will be bolt to the keel fin.
Do anyone of you have a tip how we can align the bulbs so that we are able to grind them exactly flat and which tool is best to use? electric planer? electric angle grinder? belt sander? sanding board?

Many thanks for sharing your ideas.

For those who are looking for a solution to plan the keel bulbs after casting. We planned our bulbs last weekend using this method.
