build a water mortar
Like a PVC toy.
This water mortar is made of PVC and uses a variant of the \"drill press lathe\" technique in the book \"eccentric compartment.
\"Every time you take a quart of water, you can launch the finished product!
There are more design ideas, please see the follow-up instructions. . .
Here are the parts you need :-
30 Schedule 40 PVC \"1 1/2-
Schedule 40 PVC-24 \"of 2-
2 \"end cap of PVC-
Silicone lubricant for plumber-
No. 2 Buena 224N O-rings -
1 \"x 3\" 6 Inch of Oak
2 pieces of pillow block \"x4 \"-
6 \"of 1/4\" x20 rebar-
4 \"1/4 long\" x20 carriage bolts-
1 1/2 \"1/4\" x 20 Bolt-
1/4 \"The x20 nutsHere is the tool you need :-
Drill, twist drill, shovel drill-
1 3/4 \"hole saw (
Cut off the plug)-
2 bearings with shoulder bushing (
From old skates)-
Two clips, eight of mine. gouge -
You can get O-
The rings for the premium seals are available in a variety of sizes and materials.
Use a hole saw to cut two plugs from 1 \"oak.
From the PVC pipe form on this page, we can see that the inner diameter of Schedule 40 of 1/2 \"is 1.
592 \", so the plug left after cutting a 1.
The size of the 75 \"hole fits exactly inside the pipe.
If you tighten the collar of the hole saw you will get a larger plug and if you release it you will get a smaller plug (
Because it\'s shaking).
These parts should be tightly blocked at the end of the 1 1/2 \"pipe, so it\'s better to start from too big a place and you polish it a little to reduce the plug (
Push it into the drill bit using 1/4 \"x20 bolts and nuts and opposite the sand block to get even results).
If your parts are too small, increase their diameter by adding concealer glue.
Let the tape hang slightly on the inner edge so that it can direct the pipe to the center without being pushed back.
Once you find the right location, assemble the center as shown below.
\"Drive\" center in the foreground,\"
The background is the \"drive\" center.
Use a shovel bit, drill 2 \"x4\" blocks and make pillow blocks for the bearings.
Insert the center into the end of the pipe. Roll an O-
Circle the tube.
Insert the bearing into the pillow block.
Check if the pipe rotates smoothly.
Secure the pillow block.
The transport bolts protruding from the drive center are pushed into the drill bit.
I haven\'t tried it, but a 1/4 \"x20 screw bar runs from one end to the other, and the whole setup can be more solid.
Set the drill bit at a relatively low speed and lock it.
Mark the position of the groove using permanent marking.
The first one should be at 1 \"start from the end and the second one should be around 4 below the pipe \".
Start drilling at a slower speed until you have a feel for things and then speed up the drill to speed up the cutting action.
If you swing too much in the pipe, please slow down.
If you don\'t have gouge, experiment with a different Sharp
To keep an edge object with a 90 degree angle of the pipe.
I used a round bottom.
File for my groove.
The groove should be flat.
Smooth bottom, Square
Up the side and enough width to O-
Call some room for breathing. Roll the O-
Ring into a slot, measure the outer diameter of O-
Ring with scale.
Rotate the pipe slightly and measure it in several positions to obtain an average diameter.
The average diameter needs to be about.
010 \"is larger than the inner diameter of the large pipe.
The table cited earlier states that 2 \"the inner diameter of the schedule 40 PVC should be 2.
049 \", but measure yours and add.
010 \"gets the target diameter. If the O-
The ring fits too tightly, it will be tied together, and it will not slide smoothly. If it is too loose, the water will leak it.
After reaching the target diameter, remove the pipe from the turning device.
Tilt the inner lip of the outer tube so that o-
The ring will slip in more easily.
Clean everything up before assembly.
Place damp, folded paper towels at the end of the inner tube and pass them through the outer tube to remove dust and sundries. Put both O-
Add rings to their grooves, lubricate everything loosely, and check if it\'s appropriate.
Make end plugs using one of the centers.
Insert 1 1/2 \"1/4 long\" x20 Bolt and put a nut on the other end and tighten it.
Work the end cap to the end of the inner tube.
The head of the bolt should be visible.
Once you start, you can turn the tube over, tap it on the floor and hold the plug tightly to the seat.
If the plug is not tight enough, it is sucked out when you breathe water into the chamber.
You can wrap the plug with tape at the bottom to make it more comfortable.
This is the end when everything is together.
The movement is smooth, very good, even.
Drill end cap.
A 1/2 hole seems to work well.
Get a few caps and experiments.
Place the end cap on the outer tube and fix it by tapping hard on the floor.
You can remove the lid by tapping the other end of the inner tube on the floor.
Take a bucket of water, push the inner tube all the way, place the end cap under water, pull the inner tube back until you can see an o-
Ring, quickly tilt the end cap to the air to keep the leak to a minimum, put the end of the inner tube on the ground, tilt in the direction you want to open the fire, pull down on the outer tube to catch fire.
Extra fun: If you pull the inner tube back and install an undrilled end cap, you can start the end cap with pneumatic pressure, creating an impressive explosion in the process
Make sure it\'s not for anything or anyone.
Also make sure you\'re not in the garage when you find out how cool this is, well, the people I know are: when you nail it with the tail cap, the garage door makes a loud boom!
