Rifle Tube – Fire Suppression System

I had three really hard working guys with me today.  We got the holes in the wall drilled for the sump pump and fire suppression system.  They got the ditch for the pipe 80-85 % dug out.  But, the critters are working against us.  Look at the photos where one has half-filled a spot in the trench.

I picked up the sump pump and plumbing today and hope to get it in on Friday.

I will be at the club at 09:00 Friday for all day. and 08:00 on Saturday and must leave at lunch.  I will not be back until next Friday Morning.

I have a ton and a half of pea gravel being delivered Friday afternoon to dump by the fan house fence.  This is to put in the trench with the fire system pipe when they put it in next week.  We will get the trench dug and not put it in until they are there with with the pipe hopefully next Friday.

The ditch #2 & critter stuff

I can use a helper or two next Friday (6/3) both days of the weekend.

We are going to start on the fan and filter and duct installation next.  As soon as we get it finished and the fire suppression installation in, we can put the cover on the backstop support and put the rubber in.

Rifle Tube – Work Revolves Around Fire Sprinklers

This weekend, we got all the steel primed and vent holes drilled and
trimmed in it and the vertical vent pipes ready.  We got all the steel
into the hole and the wall stripes painted.  We had another good day and
Warren and Mark got the target holder bar and mounts installed.  We also
got the fan debris deflector changed to a  larger one and verified the
brackets will fit.  This will not be permanently installed until all the
rubber is in.

Arapahoe Fire Protection Co. came by and we finalized the plan for the
dry standpipe sprinkler system.  They are going to put us on the
schedule (hopefully) for next Friday, 6/3/2016, to put in the pipes and
heads.  We got the location for the holes for this and the sump pump in
the wall located.  We are very close to being ready to put the top
plywood, steel and baffles on the rubber support as soon as we get the
fire protection system installed. (They need access for ladders.)

The box 5-26-2016

We have to dig the ditch outside the west side of the box to 18
inches below grade; this means a hole on the side of the box about 2 ft
wide by 30 inches deep to get access to ground level, and then an 18 inch
deep by 6 inch trench from there to 2 ft. outside the  fence.  We have
to dig a 4 ft by 4 ft location for a 4 to 6 inch thick concrete pad at
this location.  In the center of this we have to have a 2 ft diameter by
2 ft deep hole to fill with pea gravel for the sprinkler system auto
drain.  We then need to put 6 inches of pea gravel in the bottom of the
trench for the pipe to sit on to the center of the pad.  After the fire
department approves the installation, we have to fill the pad with
concrete and cover the pipe with pea gravel and fill in the rest with dirt.

We are coming up on the holiday weekend and I have to go to Texas
for a funeral next week.  So here is the choppy plan – Warren Johnston
knows what we need for the digging and prep work also.

I will be there Thursday and Friday at 09:00.  I will be there on
Saturday from 08:00 to Lunch.  I  have to be out of town Saturday night and will not return until Thursday night, but will be a the club on  Friday morning 6/3/2016, when
the contractor shows up.

My priorities this week are to get the holes in the wall drilled and the
dirt dug out and pea gravel base installed before I leave to be ready
for the installation the following Friday.  I will rent a core drill and
work on the holes for the sprinkler and sump pump on Thursday.

We are ready to start the fan and duct installation in the fan house.
We need to get the fresh air cut off system installed and the inlet
building cleaned up.  We are on a roll at this point.

Please let me know if you can help on any of these days?  I will rent a
core drill for Thursday if I have a helper.

Rifle Tube – WE NEED HELP!

We are in construction mode.

As of today, since the last message, we got the backstop plywood
cut and in the hole.  We got the backstop steel all drilled and a coat
of primer on one side.   We got the yellow paint stripe in the box to
show the proper rubber level.

On Saturday we need to prime the other side of all the steel  and we
also have to cut two corners off the upper pieces of steel or the
upper air vent tube installation and drill two holes in the upper shelf
steel for them.  We hope to get the red paint stripe in the box done.

We need help.  It is slow going with only one or two helpers each day.
We have lots to do to get all the small jobs done.

We have the fire protection company coming Monday to mark the hole for
the pipe and the hangers and the ditch.  Later this week we will need to
get the 3-inch holes in the wall drilled and the ditch done.   I will
need one or two highly-talented  earth specialists to dig the 17-ft long
ditch down the outside of the box and to the fence 18 inches
deep.  It will have to be done by hand.

I will be at the club on Saturday, Sunday and Monday at 09:00. If nobody
else shows up by 09:30 or has contacted me, I am going to the gun show
on Sunday.

Rifle Tube – Light at the End of the Tunnel

We had two or three members show up to help each day Thursday, Friday,
Saturday, and Sunday.  I will not be there Monday, Tuesday or Wednesday
except to deliver the filters unless something really big comes up.  I
plan to be there to work on Thursday, Friday, Saturday and Sunday at
09:00.  Please let me know if you can come help.

We have a 3-inch core hole saw for the concrete wall, but need an arbor
or the whole thing.  Anybody have one?  We also need it to drill the
hole for the sump pump and the fire suppression system.

We got the box covered with two coats of concrete sealer, and one
coat of ECOBOND Lead Barrier Primer by this afternoon.  I conned my wife
to exchange a trip to the Hamburger Stand for going in with me tonight
as my safety, and I got the final coat of white semi-gloss exterior paint
on all the walls and ceiling sprayed on and everything cleaned up at
21:30.  The only paint in the box left to do is the stripe on the wall
for the rubber level marking.

We got the frame for the backstop rubber support cut on Friday and
installed on Saturday.  We left one joist out so we can still use a
ladder there for putting stuff together, such as the back debris
deflector and the big debris deflector under the fan inlet We still have
to add 8 more supports on the back wall but they will only take a little
time to do.

Rubber Support Frame 20160515_093419 (Medium)

Mike Arnold got the baffles for the support bent and delivered.

We got the fan, shutter and hour meter on Friday.  I will go get the
primary filters on Monday or Tuesday.  We can start assembling the
filter holders and fan housing now and work on the duct in the fan house.

I met with the rep from Arapahoe Fire Protection on Friday to discuss
our dry sprinkler system.  We will have to drill a 3 inch hole in the
wall  for the pipe and dig a ditch from the wall of the box to the Fence.

We also need to replace the breaker box (antique and no space for another
breaker) and add a plug in the box for the sump pump. Then we can
install the sump pump once we get the hole in the wall drilled.

We need to install the shutoff for the air inlet in the tube.  We still
need to pull the roof off and clean the box and glue the insulation back
in place and install bug screens on it.

So we have lots left to do.  But there is light at the end of the tunnel
and, with the new paint, it is bright!

Rifle Tube – Starting the Detail Work

I will be at the club on Thursday and Friday at 09:00 if anyone wants to
come in and help.  I could use someone to just be there to check on me
when I am painting to be sure I didn’t fall off a ladder even if they
can’t do any physical labor.

I will be there Saturday at 08:00 (also a maintenance party day) and at
09:00 on Sunday if anyone else is going to come in on Sunday. (let me
know?).  Monday also depends on what we get done on Sunday and if anyone
wants to come in and if I have any energy left.

I hope we can get the box painted by the weekend.

We have a representative of Arapahoe Fire Protection Co. coming to look
at the box on Friday about a deluge system with a dry standpipe.  He and
his boss shoot pins on Tuesday so that should be a help.  He understands
that we want to do all the work we can, such as putting the holes in the
wall and digging as needed.

We need to get the 3 inch dia. hole cut/drilled/chopped in the wall and
get the sump pump plumbed and installed.  I know some of you have core
drills so hopefully the hole will go easy.

After paint, We can get the front footer of the rubber support located,
the back header located and installed, and the wall joists installed.  We
will need to install lots of wall anchors on the sides and back, so we
need the tools and any spare anchors you have.  We can cut all the
joists and get them ready to install. We can get the three sheets of
the support top 3/4″ plywood and the one sheet cut and get them into the
hole and tunnel.

The top plate steel is on site.  We need the baffles drilled or punched
and then bent.  The sheets and baffles will be the last thing
installed before we dump in the rubber.

We hope to have the fan and at least some of the filters and the shutter
on site by the weekend.  This will allow us to start the fan house
design and manufacture.  The filter housing is the only part that will
be built of metal.

Lots to do and I am sure we won’t get near as much done as we want.  But
we now are in construction mode so we can start seeing an end at some time.

Rifle Tube – Concrete Is In!

Concrete slide 20160507_132321 (Medium) Ready to pour 20160507_132307 (Medium) The Dwarfs in the mine at work 20160507_132319 (Medium)Finished & drying 5-7-2016 20160507_160849 (Medium)

With the help of master concrete man, Dan Harris, and the other 8 or so of us, we got the concrete poured.  We had to get a second truck load as the driver put too much water in the first one so we lost almost two hours, but it looks great.  The pictures do not show the footer we also poured on the back wall.

We can now really move ahead.  I met with the fire marshal on Friday and had a good meeting.  We are going to have to have a fire prevention company put in a dry hydrant with a locking cap on the fence to flood the box if it ever catches fire.  We are also going to put in a “Pull in Case of Fire” handle to cut-off on the inlet air valve in the shooting room.

We still have lots of little things to do while the concrete dries – remove the slide and clean up at the chrono’s, sort tools and others, depending on help.  I know this is short notice but could not commit until tonight.

I will also be there Monday morning, 5/9, at 09:00 if anyone wants to let me know that they will be there.  But I must leave at noon for an appointment.  If no one lets me know they are coming on Monday, I will not come in until Thursday due to  personal stuff.  I plan to be at the club next Thursday and Friday at 09:00, Saturday at 08:00 (also work party) and Sunday at 09:00.

The next step is to get one more coat of concrete sealer on, along with the ECOBOND primer and top coat the paint.  We need to prime and paint the ceiling steel mounts and bullet deflector and get them installed.  We need to change the rubber on the back deflector and get it hung.  We need to get the target holder mounts located and installed and painted.  We need to fit the debris deflector and set aside until the rubber is in.

We can then start the backstop support.  We can now also start on the fan and filter installations.

Rifle Tube – Pouring Concrete This Weekend

We are almost  ready to pour the concrete.  We got most of the forms
done this weekend and got the first coat of sealant on the walls of the
box on Sunday afternoon.

I have two yards of 4000 psi exterior slump 4 concrete scheduled to
arrive on Saturday, 5/7/2016 at 11:00 for the box.  I have three helpers
and me committed to be there and could use two or three more?

I can also use a hand on Thursday and Friday to help remove a little
more dirt from the hole and build  one more form in the back of the
box,  build the chutes/troughs to get the concrete in the hole and make
a form to pour any excess into just in case. I will be there at 09:00
Thursday and Friday and at 08:00

Let me know if you can make it to help on any of them if you haven’t
already done so.

Rifle Tube – Getting Ready for Concrete

Target box  B 4-30-2016 (Medium)

Target Box 4-30-2016 (Medium)

Moving Dirt 4-29-2016 (Medium)

We had a kick-ass couple of days moving 2-1/2 yards of dirt out of the box with the hoist and buckets and getting the box ready for pouring the concrete next Saturday, (HOPEFULLY.)  Many thanks to all who showed up Friday and Saturday and really got with it.

We will seal the walls and start paint on Sunday, May 1 and Monday, May 2.  After it drys up a little this week, we will make the concrete troughs on Thursday and Friday.  I don’t plan to work Tuesday and Wednesday.

We also installed a sump well and French drain so it was already in prior to pouring the concrete just in case we needed one.  We found water one foot down from the box so we will install the pump plumbing (cut a hole in the concrete wall) as we progress. We will probably need a pump in the future.

I really need at least four volunteers to help us pour the concrete next Saturday, May 7, if I can get it delivered.  We are going to just have a truck bring the 1-1/2 yards we need and dump it on the troughs we will build to get it into the hole.  So we need help on top and help below.  Please let me know if you can come so I will commit to getting the concrete delivered. If you come, bring your rubber boots and grubby clothes.  We also have coveralls with booties if you want and don’t have rubber boots.  Concrete deliveries are tight in Denver now so hopefully we can get it done Saturday.  But we have to have enough people there to do it.

If any of you know of a preferred concrete company in the area, please let me know by Monday Morning before I start calling around.

Rifle Tube – Start of Week 3

I will be at the club to do some work and clean up on Monday, 4/25/2016
after 09:00. Warren and Jack will be there after lunch.

With the weather forecast, I am not planning on working on the tube
Tuesday, Wednesday and Thursday.  I will be at the club Friday about
09:00 and all next weekend at 09:00.

But!  We need to get a cutting torch to cut off the 3/8 inch thick by 48
inch wide plate on the back wall.  If some one has one with O2 and
acetylene available some day or night this week, I will come in.  We
need to do this before we start the final construction of the rubber
support.  Or if you have one available this weekend it would be great.
Please let me know.

Our Rubber for the backstop and the fire preventative and lead control
chemicals got delivered on last Friday.  We got the rubber inside the
fence besides the fan house and the chemicals in the shed.

We got the fan house walls sealed on Friday, the 15th, but we had weather
that caused us to lose any work over the weekend.

The week of 4/18 has been slow due to the weather at the first of the
week.  We have gotten the walls and ceiling of the target box washed and
the water sucked out. The box is dry enough to seal with ECOBOND and then
paint when we get some volunteers to do so.  We have not had many show
up this weekend.  Thanks to those who did.

We got all the ceiling, walls and floor of the fan house ECOBOND primed
and a top coat of paint on.  We got the insulation installed in
the ceiling, and the hoist and hoist beam installed.  We have sealed the
outside stoop to prevent water intrusion into the target box.  We have
just a little more painting and sealing to do this week.  We used the hoist on Sunday, 4/24, to put stuff into the box and to lift the steel deflector plate off of its hanger.  Works great.

The floor of the target box is dirt.  We have to remove 1 to 1-1/2 yards
of clean dirt (not hazardous)  from the bottom in order to make
room to put concrete on 2/3 of the floor for the rubber. The back part
under the support does not need concrete. Lifting out the dirt and pouring concrete is going to slow us down, and needs a lot of physical labor.

We still anticipate a minimum of two weeks, and possibly four weeks or
more to finish all the work and installation of the floor and walkway
concrete, new backstop, and fan and filters.  We have a lot of tasks for
volunteers to do assisting on the tube project and other club
maintenance, if we get enough people, particularly the weekends of 4/30
and 5/7.  Feel free to help, even if you just want to take photos and
make runs to the lumber yard if needed.

We need help.  Only a few guys showed up several times in the last week
and only 3 or 4 each day of the weekend.

Rifle Tube Remodel – Resuming Work After the Storm

I dug a ditch yesterday and drained the CCGC lake by the shed.  We got
the fan house ECOBOND Primer on today.  I will put the top coat on it on
Friday and seal the outside concrete that leaks into the target box.

We got most of the target box pressure washed today except for the area
around the electric and lights which must be done by hand.  We had
plastic on the floor and sucked the water up with a shop vac so it is
not very muddy.

We have lots of stuff to do this weekend.  We could use a large fan or two if any of you have them to bring.  Not desk fans.

I will have the hoist up and running by tomorrow night.  We have some dirt
to move and lots of sealer and paint to do in the box.  I hope to get
the dirt done and the forms for the concrete done this weekend if

We also need to put the roof off the air inlet again and fix
the loose soundproofing and put in some screen wire.

I will be at the club at 08:00 Friday, Saturday and Sunday.
