Since I wrote out quite a bit on my last post
(recheck it out, I edited a few times, adding more and more, as I usually do),
I'll just cover a few details in this FULL DIY to break it down a bit more.
So in this first DIY post I'll list the tools needed, and parts to make the arms.
Along with the costs, so you get an idea as to how much it will cost per arm.
Some of you may only want or need one arm for a monitor or laptop.
The arms are identical up to the monitor and laptop mounts, so let's start with the arms first :
Tools:
Drill press with a clamp to hold pipe.
Hand drill to drill holes in organ.
7/16" open end wrench to tighten lag bolts( if you get 2 inch, 1/4 inch lag bolts, the heads use 7/16" wrench).
1/4 " drill bit for the holes through the pipe.
1/8", or 9/64" drill bit for the pilot holes into the wood of the organ(I forgot what I used, but read note below).
Note: Whenever you screw into wood, it is always important to first drill pilot holes, so you do not split the wood,
they make screwing easier, and allow you to aline the pilot holes so that the bolts go in streight.
For pilot hole drill bits, I look at the screw or bolt, and pick a size that is smaller than the inside non threaded part of the screw or bolt,
then go a bit smaller.
You DO NOT WANT YOUR PILOT HOLES TO BE TOO BIG, ELSE YOU WILL NOT HAVE THE THREAD OF THE BOLT BITE INTO THE WOOD,
AND NOW YOU HAVE DESTROYED THE WOOD FOR SCREWING INTO.
You can alwsys start smaller, then go larger if bolt is too tight to turn in.
You are drilling into a fine piece of furniture, and you do not want to detroy it!
There maybe recommended sizes listed somewhere, but this is how I determine the sizes.
Pilot holes are just there to remove a bit of wood so the bolts do not split the wood, etc.
So they need not be that big.
Just make sure the pilot holes are not too big else you will not have a thread in the wood to secure the bolts!
Parts:
2x 2 inch long, 1/4 inch wide lag bolts $0.50 (Home Depot)
1x 1/2inchx5inch Galvanized nipple $1.75 (Home Depot)
1x 1/2inch Galvanzed Coupling $1.76 (Home Depot)
2x 1/2inchx12inch Galvanized nipples $7.32 (Home Depot)
1x 1/2inch black pipe(normally gas pipe) 90 degree elbow $1.37 (Home Depot)
1x 1/2inch black pipe(normally gas pipe) 45 degree elbow $1.59 (Home Depot)
1x 1/2inchx4inch Galvanized nipple $1.49 (Home Depot)
1x 1/2inch black pipe(normally gas pipe) 45 degree street elbow $2.32 (Home Depot)
1x 1/2inch Pipe Flange $5.60 (Home Depot)
-------------------------------------------------------------------------------------
Total parts cost: $23.70
Lag bolts are found in the hardware section with screws, etc.
The rest are all found in the plumbing Ile, even the black gas pipe fittings.
The galvanized parts are cheaper than the black pipe parts(and look a bit better, I think).
So try to buy as many galvanized parts as possible.
But for some fittings I had to get black gas pipe fittings, since there were non in galvanized.
So for less than $25 each, you have arms!
In my next post I'll post a few pictures of the tools, parts, and touch on the drilling and assembly.
This is pretty much streight forward, so this is not too involved.
But wait until my next post before you drill or assemble the arms,
since there is a sequence in which to drill and screw them together right.
