Home Mechanic Tools

If you make a DIY chain whip, make sure you give it a proper handle...  Mine has a tendency to dig into the hands and it is quiet painful.

I will Make what i think is a good idea today and post some pictures only problem is that my oxygen acetylene kit is out of oxygen, another advantage is that the bottle has a vallve ontop so the bottle could be pressurized and the valve closed and this would make it nice and safe for any transportation or anything similar. P.S if anyone wants a cylinder give me a shout im in centurion

Hubbers are helpful people! You cannot deny that fact!

 

I have been doing my own bike work for years and between a couple of friends we have all we need. A lot has been said about tools below but for me the most useful thing is my Park Tool work stand. I have a foldable stand so I can take it along when I need to, invest in a good one and you have a partner for life. Just be careful with the clamp, do not over-tighten and see where you want to clamp. Sometimes better on the frame, sometimes on the seat post, just depends. Also have a tool tray on my stand and holder for cloths etc.

 

Torque wrench...Patch is right, get a good one. I prefer Norbar (a lot of the Gedore TR are also Norbar). They are in Jhb and will probably sell direct if you ask. A 0-10NM and 10 - 50NM (you need 40 NM on a cassette) will be perfect.

 

You Tube, manufacturers' sites, books etc are excellent references and remember force is most often not necessary....

 

Finally, have confidence, it is easy stuff once you have done it a couple of times, and yes, you will make mistakes.

Some questions on your fire hydrant / gas cylinder contraptions:

1. What pressure can it be filled to? Obviously the pressure would determine the number of tyres one can seat, before having to refill the cylinder.
2. Where would one "refill/repressurize" it? Assume a mini-compressor at home or at the local garage - both of which might not have that explosive power required to seat the tyre.

The cylinder (above) is primarily designed to store products in a high pressure or liquid state, i.e. nitrogen, oxygen, CO₂, LPG, or refrigerant, etc. with dedicated refilling sites, so I know it's more than good enough for a home-made tool.

The Cylinder above is as you say a standard pressurised vessel so it can handle a huge amount of pressure. i HAve done a quick Calculation and the cyclinder will easily hold up to 30 Bar i would imagine that roughly 12 Litres at 30 Bar could seat a ton of tires. And Also the Vessel Has a Safety valve tha if over pressurised will blow a safety seal. I have a License in Gas Handling and I would never evr ever use a 2 Litre Bottle or the Likes its an Accident Waiting to Happen Rather come and get a free Bottle.

 

Edit it equates exatly to 360 Litres 12L x 30 Bar is 360 LItres Thats alot of tyres

And how would you fill it - a normal compressor?

With regards to the 1kg fire suppression canister, I pumped it with a floor pump to about 9 Bar and that was sufficient for seating a wheel (especially if you take out the inner value)

I have my Fire Extinguisher  tire popper at home I made about a month ago. 

(still need to post pics )

 

Most info is on the cylinder.  

On mine is the following.

 

Tested pressure: 30 Bar.

Working  Pressure: 15 Bar. 

 

I have a nice one with pressure gauge and the "refill" valve (normal schrader valve)  in place. I don't sit around and ponder the pressure in the thing. 

 

I pressurise it with my T-Max Electrical 4x4 compressor pump  from the car battery at home.

 

But the highest I go at home  is about 8-bar, then I am reaching limit of the pump.

 

But I have used the Fuel Station/Garage  tyre pumps as well.

Just pressurise till it does not fill anymore,in other words  my vessel and the garage compressor tank is equal in pressure. 

Never encountered one that could even reach the 10-bar mark on my gauge.  

 

I recon my "home-made DIY" model  is quite safe as I don'e even reach  a 3rd of the tested pressure.

I had the option between this type  of cylinder ( mine was car aircon refrigerant vessel) and the Fire Extinguisher. 

 

I chose the Fire Extinguisher as it was made from much thicker steel and had the pressure gauge and normal schader refill valve  on it from the factory.

 

I only attached the appropriate connector to the end of the pipe to connect it to my tire valve.

 

And I upgraded the pipe itself  to proper 8mm  air compressor hose. 

I used all pipes and connections in 8mm (truck or earth moving equipment) format instead of the  standard 6mm connection/pipes to get higher airflow.

And how would you fill it - a normal compressor?

Yup Normal Compressor or hand pump or gas station doesnt really matter. all the stuff used is Refrigerant quality and can handle up to 30 Bar. If you look at my posts you can see that it took about ten minutes to put this together it would be very easy to include a pressure gauge or lever valve to block rubber hose.

Will this set ne sufficient to do lets say 90% of maintenance?

It all depends on the bike that you have.  It will cover a number of options - such as the older bikes with square taper cranks or outboard BBs and entry level cup and cone wheel hubs.  If you have a press fit BB, 11 speed drivetrain and through axle wheels you will need to add tools.  Not a bad buy if you don't have any tools - like hex keys or screw drivers - but it certainly is not complete.  I would opt to buy the right tool for my bike as the need arises.

It is a nice starting set, but also depends how OCD you are, are you ok with mixing brands or not, ie if you start with icetoolz do you only want to buy icetoolz, or going for the mix and match approach.  

 

What I can say, it really make a difference having the correct tool for the job and then working on your own bike.

[Theunissa]

I'm not OCD. As long as it is decent. David i hear you. I have a 2016 sola 4. I will look at what exactly is in the bike parts wise and buy according to that
