Re: Drawings for BCAL assy



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.

Cheers,

       Tim

Dear all,

Tim may I suggest you ask Paul Eugenio FSU has a very nice shop from what
I heard. Maybe that do this for us, assuming the overhead does not kill
us.

cheers elke

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...

Hi Zisis,

The deadline is yesterday ;-) . We plan on getting a 1/10th scale
made of it some point in the near future. 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

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.

Cheers, Zisis...

Hi Zisis and George,

Attached are the most recent preliminary drawings showing the
wedges and
assy. 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.

Cheers,
