* The cylinder head is identical everywhere (unless I build a variant with valve timing). There is also a variant with a ring for a keychain. For optical reasons, I recommend fixing the cylinder head with four M2 screws. * The crank (shaft) differs...

To be sure to get a nice seal, I recommend you put a thick layer of silicone (or glue, but the silicone is easier if you ultimately want to diassemble the system) where the stock oring is supposed to be, assemble the system, and let it dry long...

Adjustable self-watering spike for indoor and outdoor use. By using a plastic bottle you can provide the garden plants with an adjustable drip irrigation system. By turning the valve you can adjust and control the drop...

Human: Adapter with integrated caps for closing exhale ducts (forcing the air through front valve and preventing moisture from damaging the filters).\r\nThis project is optimized for quick printing.\r\n\r\nThe model has passed initial printing tests...

... in servicing a fork yet. I have printed out a set that I've given to two friends who are bike mechanics in the interest of testing. In case you're wondering, the duck in the photo is my Rubber ducky valve stem cap which I made around the same time.

I designed in a valve to allow extra air to the vacuum to prevent the motor overheating, but it needs to be fully closed. I under estimated how much air would get through the array of holes. My goal was to have the holes small enough that the...

How I Did This Model This wasn't a design on my part - instead it was ripped straight off the Valve's model on Dota 2's workshop area, then decorated with those extra designs that really take center stage & were created by those who're way more...

After printing, remove any support structures remaining, and use a small file to smooth the flat undersides of the bolt, round out the bottom rear edge where it interfaces the hammer, and slightly round the edge of the right sear where it interfaces...

Its operational prowess stems largely from custom alterations made during a later development period after initial B-26 invader designs had begun – namely modifications added on engines as seen with Marketeer types – along side conversion work...

General Concept An AMBU bag is used as a pressure reservoir, featuring an O2 inlet (O2 concentration is crucial for patients with acute respiratory syndrome) and several safety features, including overpressure and bypass valves. These bags are...

You have to cut a 290 mm long peace of pipe. Fire extinguisher valve. I get from an old fire extinguisher and was a 30 mm screw. If you don't have it you can find on amazon a simple manometer. I think the effect will be good.</li> <li>Emergency kill...

Make a note / take some pictures of the position the nut in relation to the tyre's valve so you can check it's not coming undone. Assemble everything off the wheel first to make sure the threads are ok and it goes together well. Can all be...

An instructional video will be posted soon, but in the meantime: --The exhaust and intake valves use a diaphragm cut from a zip-lock bag. Cut this into a disk just big enough to cover the vents. These diaphragms are held in place by either the...

By default the exhaust cam is off by about 1-2 teeth after installing due to the loading from one of the exhaust valve sets. This wrench will allow you to Rotate the exhaust and intake cam to allow enough slack on the cam chain to move it a...

... to ensure good running. I suggest adding 8-10 grams for an all-up weight of 18-20 grams in 1/160th scale. I consider this design as complete apart from a design of the air-brake control valve. ...I hope it will be useful and I welcome improvements.

Place tools and wooden plates in your reach and open hot water valve. Temperature should be between 65-70°C, (if it is too hot to hold your hand in it, it will probably be ok) too hot will shrink your leather too much, too cold will not penetrate...

As the cam rotates, these lobes come into contact with a follower, which rides on top of them, and are pushed out of their normal position, creating a precise movement that can be used to operate various mechanisms such as valves, gears, and other...

We encountered numerous issues, from leaky pipes to faulty valves. Despite the challenges, we refused to give up. We continued to tweak and adjust our design, making crucial improvements along the way. With each iteration, our engine became more...

Main Gear Box, Turbine Active Cooling Duct (HPT, LPT), Variable Vane Linkage (LPC, LPC), Bleed Valve (LPC) B. Video (YouTube) https://youtu.be/xlXpy2o3c8Y C. Assembly Manual (PDF format, total 31 pages) The detail assembly manual including...

Our half mask does not comprise an expiratory valve, and the humidity aggregates in the filtering medium; similarly to surgical masks, there then forms a potentially bacterial environment, meaning that the filter must be dried and disinfected or...

The roller shutoff valve will allow you to regulate the rate of flow coolant. ... Once the 3in1 oil is gone, I'll try refilling it with real aluminum cutting fluid, but as it is, it seems to work fine – nice finish, hasn't caught fire, and haven't had...

Underpinning its impressive performance is a 6.1-liter displacement gasoline engine, an unparalleled V-60 layout coupled with twelve valves per cylinder to provide the ultimate propulsion. Its longitudinal rear-center-mounted setup, developed by BMW...

The model does not include a Clippard Valve, as I recently released my own R-331/R-701/R-501 model based on Clippard's own CAD data and my measurements from a live 80's Vintage R-331. This wand works with my Loom Couplers available here. A Youtube...

Rotating in one direction, the bucket drum scoops the regolith, which is then immediately redirected and passes through a Tesla Valve-like mechanism (ZAG). The ZAG prevents regolith from escaping, allowing it to fill the internal volume. As the drum...

The final objects have the lamps removed plus the clack valves better fixed to the boiler. All six lamps are now separate fittings. See "699 LHS rework" and "699 RHS with fixes for floating parts. The model was then cut into pieces to avoid...

This is my design of a headphone/ear cup for the pimax 8k,8kx SMAS headstrap. The sound volume &amp; isolation on the Smas headstrap is quite poor as standard. This modification will clip over the top of the inbuilt headphone, hovers over your ear...

Maximum efficiency is achieved when the element pressure ratio matches the working pressure required by an application.One of the advantages of screw compressors over other technologies is that they are generally not equipped with valves and do not...

It's best to obtain the type of pipe without the valve at the bottom since it serves no purpose. You can find flexible coolant pipes on Ebay by searching for them. The flexible coolant pipes I bought have 1/2"-20 threads at one end and a nozzle at...

Any tension on the bolt heads would just tear them out or stretch them, only making the issue worse. I worked around that by using washers. After about 5 weeks, the shroud started sagging and as the weeks went on, during some infill operations, the...
