Heidelberg KSBA letterpress

Hi folks, My 18 x 23” cylinder is not starting. Any advice for who to go to in the Peterborough Ontario area?

Not sure this will help, I don’t own one of these - wish I did. Power switch contact point can arc over time and build up carbon until they fail. I have taken them apart and cleaned or replaced the contacts. Power inverters can have a fan that must start first to cool the unit. The fans are generally low power. I had a printing press do this. They can get dusty and as soon as some moist weather hits they get to heavy to spin and thus no power startup. I cleaned of the fan blades and it started up. I am in a Fred Flintstone building. I had a breaker I thought was partially tripped. I flipped it off and back on but it still felt a little off, so I thought maybe I had a bad breaker. I had my electrician come in and he laughed and aggressively turned it off hard then back on hard and we were fine. I guess old breakers work different than modern ones. Good luck, let know what happens

Did you get that solved? I’d look closely at the switch for the delivery cover.
In the Detroit, Mi, US area we have had service on ours through F C Washington & Son.

Thanks. The problem was starting okay on Wye/Star but shut down when supposed to switch over to Delta. Press is operational now but I would like to find a local electrician that is skilled with motor controls to ensure all is working properly. I also have a concern about parts as the press was made in the 1960’s. Peterborough used to be called “The Electric City” because of the huge GE plant, sadly not so much now.

I don’t know what size the motor is on that press, but unless it’s bigger than 4-5 HP or your electric system isn’t good, a W/D starter probably isn’t needed.

Parts might or might not be available for the existing motor starter, but much as I like the old stuff, I’d consider asking the electrician to install a “soft start” or just go with across-the-line starting. Unless you -need- electrical speed control, you don’t need a VFD (variable frequency drive).

Look for a commercial service electrician, not someone who does only residential stuff.
