With the platform down, I have been contemplating how to assemble the dome (Pulsar Observatories 2.2m), making sure that it is secured always against the wind; which can gust here at ~100mph.

I have designed a stainless-steel bracket, several copies of which are to be bolted to the cupola. This will allow me to anchor the cupola to the concrete platform. I have bought marine-grade, stainless eye-bolts for this purpose.

So I can source my brackets could some kind person please recommend a supplier of small metal orders who preferably will also laser-cut?
