Elke, I have spoken with Paul Eugenio and he seems to think it would be no problem. He is traveling and will get with the shop next week when he returns. I will have James make a scale model drawing. Matt, I will like to keep your offer open also.

Maybe that do this for us, assuming the overhead does not kill us. cheers elkeDate: Wed, 5 Dec 2007 12:40:50 -0600 From: Zisis Papandreou <zisis@uregina.ca> To: Tim Whitlatch <whitey@jlab.org> Cc: George Lolos <George.Lolos@uregina.ca>, halld-cal@jlab.org Subject: Re: Drawings for BCAL assy Hi Tim: phew, and I thought you wanted it last week! :-) Actually, your time scale for the 1/10 model rules out or local shop and that in Alberta. Off the top of my head, any project short of a few holes drilled needs a few months from us to get it in the queue and organize communications. I conclude that you would have to pursue it at a local shop in NN. However, for the full construction we will discuss your questions with the Alberta engineers. Cheers, Zisis...

This would be helpful in proving out the concept. Maybe your shop can make the scale model (is it within the university or an outside shop?)? If not, we can pursue having it made at a local shop. As far as the time frame, I believe a couple of weeks is ok. Regards, Tim Zisis Papandreou wrote:Hi Tim: sorry for not replying sooner. Thanks for the drawings. Is there a deadline to your questions? We are currently swamped with work related to the calorimetry review, plus our university's support staff just got back from a one-month strike, so everything is still in disarray here.

The datums and tolerances need to be worked on a bit. I believe we could start with a tolerance of .010 inches for each dimension and change from there if needed. I will send you another update by the end of the week. Please have your shop look at these to see if they can machine them. One of the questions would be "Do we machine the aluminum first, then layup scifi/lead, then machine the lead? Note there are 3 different aluminum strong backs depending on position.
