 It's not bad Matt offroad recovery uses it to pump tyres amd it works good. 

at least I know my taste in youtube is shared in this thread hahahaha

get a little more life out of those cans.

Saved a couple cans of Q20 like this

Nice. This can work well with my 4x4 compressor. I only use a foot pump because I must 

I am just curious. What do you use for a 4x4 pump?

 

Years ago I was a guest on a very remote Kalahari game farm and when the hunting was done, we helped with the regular farm work (We've got to pay for the free accommodation😉). Two things I learnt there. 1. A manual sun tracking device for borehole pumps, and 2 an additional air conditioner pump in the cruiser for QUICK inflates in the field. Both worked like a charm.

I have an older model air compressor made for/by bmw for the GS bikes. Lovely little bit of gear. But it has been abused and I love Makita. Hence my thoughts on the Makita tyre inflator.

I have the small (I think) Makita and it is a little bit cumbersome (doesn't have a dual nozzle for bicycles, have to use an adaptor) and isn't that quick (on car tyres anyway) but nice to set the pressure needed and leave it.

I am not a 4x4 owner but I've seen the time some of these guys take to re-inflate after they get out of the sandy 4x4 routes. Some of them had the best mini compressors money could buy and it still took forever to re-inflate. AND the noise! The speed and convenience of the onboard 2nd compressor were something to behold. I think most underestimate the volumes of air those aircon compressors can move.

Additionally, it's mounted on the engine, activated with a switch and all the driver has to do is connect the hose to the wheel. For home, I've made an adapter to fit on a Sodastream bottle. It's a super duper CO2 bomb. Note, this thing will blow your wheel (if it is a bicycle wheel) to smithereens is it is not controlled. Those bottles are charged to 160Bar. Do not mess around.

I have seen similar built with old gas bottles and fire extinguishers. We used to use bead blasters on the quad bike tyres to seat them. But for a just in case and to top up tyres after dropping the pressure it is fairly convenient.

It is rainy season here on a dairy farm so the mud is let's say 'festive'. I have pulled 9 vehicles out of the mud on our property this year alone. I usually try my best to do it without dropping tyre pressures but in the few occasions they have really done a proper job it is convenient to reinflate the tyres again.getting out the big compressor is also a pain.

Not the most exciting tool addition to the collection, but decided the little Makita battery powered vac needed some support from a Festool corded vac, to tackle the more dust intensive tools.

Let's see if these live up to all the rage (much like how my wife insisted we needed a Dyson Stick Vac 😅 )

So I tried out the Festool vac last night and it's significantly more powerful than the Makita. Tried it out on the mitre saw and there was a notable difference in the amount of dust left behind after some 2x4 cuts.

I'll likely keep the Makita for a while as it's cordless, has AWS (bluetooth tool activated start), although only 2 of my tools have this capability. Also the vac bags are a fraction of the price of the Festool ones.

But this Festool can suck the chrome off a tow-hitch, so if I find I don't neeeed the cordless capability, and if I spring for the Makita AWS receiver (which will enable the Festool vac to be activated by Makita AWS tools), then I may flog it.

Let us make a tool. At work, I have access to 3D printing. I want to make a chain keeper. The Morgan Blue ones look nice and are cheap overseas—I cannot find them around here.

Since 3D printers are not too happy with overhangs, I'm going for a 2-part design that will snap together. I've kept my dimensions very tight—I have a lathe to tweak it should it be required.

Below are pics of the two halves separated:

 

 

I would like to appeal to your collective wisdom. Is snapping together a feasible idea? I don't know much about the material properties of 3D printed plastic (The filament I plan to use is PETG due to resistance to solvents.)

If my idea is not good, I can also do a single print with a 45-degree overhang and either make the design work like that or cut away excess on the lathe.

Please let me know what you think.

In principle I see no reason for it not to work.  I would not mind having one of those available when working on the bike or even transporting with the rear wheel out.

Please tell more about how this is to be used ....

 

Is this a "chain guide" ?  Then why the wheel design ....

 

Is it a "jockey wheel" ?  If so, what about a bushing or bearing setup ?

 

 

 

Just trying to better understand the design concept.

Wow, that's a very neat trick, never saw that before.  Will use it for sure.

As far as I understand its to keep the chain in place when transporting or anytime the rear wheel is out, preventing the chain from hanging loose and slapping around.

Park tools call it a dummy hub. Because quick links have a limited lifetime, it is a useful way to clean a chain with the rear wheel removed.

The plastic material will have low enough friction not to require a bearing.

I became aware that designing an annular snap fit (the way some plastic containers close) is above my abilities. Therefore, I have resorted to a thread. M22 is coarse enough that slight dimensional deviation will not cause havoc. 

I'm going to start the process tomorrow morning, and I will report back. There is a good chance I end up ordering one after failing to produce it. I have learned that DIY is most often not a way to save money, but it is fun to learn new things.
