I am guessing you are talking about John Flynn. He sells plans for those machine frames on his website. He uses PVC pipes and sells the end things to keep them together. I had the oppoturnity to meet him and attend one of his lectures. He passed his quilts around while he spoke. I couldn't believe what beautiful work he does! He was an engineer who designed bridges and took up hand quilting when his wife showed an interest in the art. He has also designed a hand quilting frame, also available on his web site. Both his hand and machine quilting are amazing. I would suggest you do a google search for his site, as I do not have it bookmarked.
