Results: worked out great. The 8 to 12 hp Phas-a-matic had three 400-480 mfd capacitors. Perfect. I just desoldered the wire going from #1 to the other two and it fired up the 5hp motor first shot. Red indicator light worked as it should as well. Seems like a winner. And it had been...

Yup, I'm well aware of the hp reduction with a static converter. However in this case I'm running a 5hp 3-phase motor on a dust collector in a situation where a 3hp motor would give me more than adequate suction. I also could just use my existing 10hp rotary converter that is sitting idle. I...

Question for you phase converter pros. Can I change the capacitors on a 8 to 12 hp STATIC converter to make it suitable for a 5 hp motor? If so would that be the only thing in the box that needs changing or would I also need to swap the resistor for a matching resistance to the new setup? For...

Closing this out. Solved. This door might be opened a few times a year. That is why it is insulated and the lower cost extension springs are my selected option. I have managed to find some 210 lb extension springs at a reasonable cost so have gone that route. They will obviously have safety...

Yeah.......that's why there are safety cables running through the extension springs now. I have those on our house and shop garage doors. BH

I have a custom built, 4-section, overhead wood garage door that is 10-1/2' wide x 7' high. The weight prior to raising this current problem was 165 lbs. so I had 160-170 lb extension springs installed and the door was nicely balanced. Then I added 10 lbs of 3/4" polyiso insulation and 44 lbs...

I'm thinking about building a new small barn at home. It will be built into a slope so will have a main floor with a drive in concrete floor lower level. I'd like to put a full size lift (replace my MaxJax) in that lower level. Question is what I should use for ceiling height. I'd like to...

Personally I like to sleeve any pipe I put in the ground. 4" PVC drain pipe is very inexpensive. I would run that in a trench that is at least 12" deep. I'd then run a 3/4" black polyethelene pipe (the stuff that comes in 4' to 5' diameter rolls) inside the 4" PVC. Finally when back filling...

I'm working on installing my new Max Jax over this holiday weekend. Of course I can't call Max Jax tech support until Monday so thought I'd describe the situation here and see what you good people have to say. I've got the Max Jax posts bolted down to new 24" x 24" x 8" pads that I had...

I'm part way through the installation process for my new Max Jax lift. All assembly is done and I've determined my post spacing. Next up is drilling the post mounting anchor holes. In doing all this I've read through the manual several times and have two questions. 1) In the manual it...
