Lewtak Pipe Organ Builders

We are delighted to announce that our firm was selected to build an organ for a brand new church in Horsens, Denmark. This will be our first overseas project with which we also break a historic barrier – we will become the first ever American firm to build an instrument in this country with consistently great organs and meticulous builders. We are deeply honored and thrilled to have been chosen, and are excited to deliver a one of a kind instrument. The specification calls for 26 stops, including a 32’ Contra Bourdon in the pedal.

We will be posting frequent updates, so please be sure to visit this page often.

• All labial metal pipes –thickness of metal tapered toward the top
• All foot holes – almost completely closed for later adjustment by the voicer
• All open metal pipes larger than 1’ – will be tuned with a scroll
• All open metal pipes smaller than 1’ – will be cone tuned
• All open metal pipes smaller than 1’ – extra solder seam reinforcement near the mouth
• All stopped metal pipes – tuned by movable caps with soft leather lining, NOT felt
• Caps for the stopped metal pipes will be arched
