Rifle Tube – Fan House Nearly Complete

We had a great four days this weekend on the fan house and tube.

The fire dept bought off on the fire suppression system.  We got the concrete pad poured for the FDC and the trench filled in.

We got the fan temporary installed and verified that it is easily removable and the duct connection works.  We will get the motor installed this week so we  can size and get the belt and be ready to install it.

We got all the carpenter work in the fan house done and all the walls insulated except the very last part that we will do after we dump the rubber in.  (This is just so we don’t damage it during the moving of 160 each 50# bags of rubber. )  We got west wall side of the duct work top insulated and installed.  We have all the other tops and foam cut and located.  They just need to be glued and screwed together and taped and then installed.

We should be finished with the fan house with one or two more days for a couple of people.  We can then get the air defector fitted in the box, the bullet deflector installed, and the lower vent pipes installed.  We can then put the final plywood and steel in and then dump in the rubber.

Warren has been working on the air cut off and has the cable and  conduit installed and in the finishing phase of that.

We are on the final leg.  IF we get enough help. We should be close to being ready to do some test shots by the end of the weekend.

I know it the 4th of July weekend, but I would really appreciate any and all help.

I will be here Tuesday, 6/28, as I have one helper confirmed, and then Thursday, Friday, Saturday, and Sunday at 08:00. Please let me know if and when you can come. If you are going to come any day after lunch, be sure and let me know so we don’t leave early.

Rifle Tube – NEED HELP in the Homestretch

The Fire Dept. has approved the fire suppression system.  We can
now cover the trench and pour the concrete.  We have the concrete and
mixer on site and are ready to go.  I need help doing this.

We have all the boards cut for the duct work in the fan house. We have
all the walls with foam on them and 50% of the horizontal panels with
foam and tape on them.  We have to finish the cap and the other two
access panels with the frames and insulation to get ready to install
them.  I need help doing this.

We got the fan temporarily installed today for fit and function. We
found a 1-hp motor in the shed in a box marked 1-1/2 hp, so we are good

We are ready to fit the overhead deflector in the box and then put on
the top plywood and steel and start pouring rubber.  I need help doing this.

We need help.  We need help.

I will be there Saturday and Sunday at 08:00 as long as I can get
help.  Only one person has guaranteed that he will be there tomorrow and
only one maybe for Sunday.

Only a few members have shown up (about 22 out of 516); several of
them have on many days. (thanks to all of them). If you want to
shoot in the tube, come help us finish it please?

Rifle Tube – Need a Smaller Fan Motor

We will be in on Sunday morning, 6/19,  at 08:00 to beat the heat if
anyone is going to come help on the rifle tube.

I had planned to use the 1-1/2 hp motor we have at the club on the
rifle tube exhaust fan.  I have reviewed the data and really feel that I
did not look at it correctly and that this is going to be way too much
motor, plus they are extremely heavy.  At some time, one of the members
said they had a 3/4 hp or a 1 hp 220vvolt motor we could use.  If any of
you do, please let me know ASAP or I will go get one this week.

We are have all the wood cut for the fan house and the cross-braces
installed.  We are starting to put in all the insulation and closing the
duct work on Sunday.  As soon as the fire dept. blesses the sprinkler,
we will pour the concrete and fill the trench.

I will plan to work next Thursday, Friday, Saturday and Sunday (6/23
thru 6/26 coming in at 08:00 each day to beat the heat. Let me know if
you can come help.  We need a bunch to get the tube finished and reopened.

Rifle Tube Update – Fire Protection In, Fan Ready To Fit

Arapahoe Fire Protection, Inc. got the sprinkler system installed
today Thursday).  We also got the signs on the fence.  We have  to get the
Cunningham Fire Dept. to approve the pipe and then we can cover it up
and pour the concrete at the stand pipe.  No schedule for that yet.

We got some more painting and caulking done and got the fan ready to fit
to the box.  We will really be on a path to completion this weekend
depending on how much help we get.  I will be there at 09:00 Friday,
Saturday and Sunday.  Please let me know if you are coming to Help?

Rifle Tube Progressing Well

Ed. Note – this item may appear to be a bit dated at the time you read it. I have been at Cub Scout Day Camp all week and away from my computer, so now I’m catching up. To get the most up-to-date report on progress of the Tube, try to attend the Membership/Board Meeting this evening, 7:00 pm, at the Club.

We are awaiting the arrival of the fire department connection standpipe
at the installation company so they can start the install of the fire
system.  We do not have a schedule for this yet.  The moles have pushed
a lot of dirt into the trench that will have to be cleaned out to
install the pipe.  Once the fire system is installed, we have to pour
around the stand pipe connection.  We also need to prime and paint the
safety pipes that we will install into the concrete to keep people from
running over it.

We got the fan box installed this week end.  We need to get the inside
primed and painted.  We are ready to start the sound proofing and
installing all the duct work and the fan.  We will then remove the fan
and filters and set aside until we get the rubber installed.

The fan box #1 (Medium)

We are making lots of progress, but still a lot to go.

I will go out some time this week to shoot and also prime and paint the
inside of the fan box.  I plan to work Thursday, Friday (until noon due
to M.D. Appointment), Saturday and Sunday at 09:00 if anyone wants to
come help.  Please let me know if you are going to come?.  If no one
else comes, I am not going to do much.   If anyone wants to come in the
evenings this week, let me know and I will meet you there.
