Arno St. Denis specializes in welding and machine work on motorcycle engines - particularly aluminum engine case repair and repair of broken cylinder fins.
He has repaired my damaged Henderson lower crankcase, and has repaired Hen crankcases for a number of members of the AMCA Chesapeake Chapter. He also welded the Hen's damaged generator bracket.
My 1954 KH transmission drain plug was stripped, and the engine oil drain had previously been heli-coiled. I don't like heli-coils, as they tend to eventually come out - usually at the most inopportune time. I had Arno drill out the areas, weld in pieces of aluminum billet, then machine new drain holes. For both the Hen and KH repairs, you can hardly tell that they have been repaired.
Arno is a one-man business, working out of his home shop, in the Maryland suburbs of Washington, DC. He does an excellent job and his prices are reasonable for this specialized work. Turn-around time is variable depending on workload, but is usually 2 or 3 weeks. Both times he finished the job at the price quoted - in the timeframe quoted.
