Heat treat oven parts question

[JAG]

Ok Dogs, I am going to try to build a heat treat oven with a friend of mine. I have the plans that are available on this site somewhere. The thing is I have had an electrician look at my electrical and I cannot go 220. I am going to have to deal with the 110 for now.
I am going to get the insulating fire bricks next weekend and I need suggestions on the PID, SSR and anything else I will need. Auberins.com has some good one's but i need to narrow it down. I am hoping someone has built one for 110 and can recommend everything I will need. Any help would be greatly appreciated!!2thumbs
Also, Has anyone here built a 110 unit and what kind of heat times are you experiencing?
Thanks! Jerry

I order most of the parts from his sources.

Good luck I'm still waiting on my brick where did you get yours from?

Hi Doug, I found the brick locally through a building supply place that handles refractories. I called these guy's http://www.thermalceramics.com/site.asp?siteid=4&pageid=55 and found someone locally who sells their K-23 insulating fire bricks. Thanks!

Page 3 of this thread- http://knifedogs.com/showthread.php?t=8373&page=3 -shows some pics of the one I built. I ordered a 1700W 110v element and 12 ga. high heat wire from Duralite, and got a basic PID, high temp. thermocouple, and 25 amp SSR with heat sink from Auber Instrument.
Mine takes almost an hour to reach 1600 F but works well once it comes up to temp. I have 20 amp breakers in the service panel, but I have a long-ish cord on the oven to reach the outlet and I have doubts that I am getting the full 15 amps that the element should be pulling. It is possible that you might be able to shorten the time to temp if you have stronger circuits.
