Questions for making a home made tyre changer

[_Stretchie_]

Following on from Wideboy's thread the other month HERE (http://forums.sv650.org/showthread.php?t=181747&highlight=tyre) I am planning on making a manual tyre changer and bead breaker for my garage.

Not doing it right away, I'm looking into it first but I want to make one to this design

http://i76.photobucket.com/albums/j11/Stretchie_/Bikes/Tyre%20machine/TyreMachine1.jpg

Which will probably be mounted about a metre high with the bead breaker (like the one Wideboy made but out of metal instead of wood) attached to the frame below.

Just wondering if anyone with a home made or similar designed one has any tips, for example, the white blocks on this one are aftermarket and called Mojo blocks, nylon I think, and won't damage your rims, but they are from America. Any idea on where I can get these over here?

There is also a 'Mojo bar' that they do as the bar lever with nylon ends for removing and re-installing the bead again to protect the rims but I have seen a different bar that I'd like

http://www.ebay.co.uk/itm/manual-tyre-machine-changer-bar-alloy-wheels-car-bike-/170902428784?pt=LH_DefaultDomain_3&hash=item27ca941c70#ht_500wt_1182

So any idea's, I want to stay with this design, I like that it will grip the rims instead of just having a threaded bar come up through the centre which you then tighten a big washer type thing down on to the wheel.

There will be a metal bar/shaft coming up through the middle though to use as leverage for the tyre bar, and yes, I do plan on balancing the wheels afterwards but one thing at a time



Cheers ears


P.S. When I do make it, it will be getting tested on Squirrell Hunters bike and if he come to no harm I will start using it on mine.

Cheapo version: 3m length of 3x2 or 4x2, a large garden hinge and two lengths of 2x1

Use the the axle or towball of the Disco

Cheers fella but Is that just to break the bead?

Also, I WANT to make something like the OP, as a little project if nothing else. I want to MAKE something

What a complicated, expensive f*** about.

Option 1
Spare car rim, add pipe lagging, big bolt and wingnut to attach to workbench: done.

Option 2
Carpet tile on floor. Done.

Option 3
Put wheel on top of a spare tyre. Remove tyre. Swap tyres round. Refit.


But if you insist on making a tyre machine without any of the benefits of a tyre machine then feel free! I can probably find you some nylon stock that 2 minutes with a saw and file will turn into those blocks for you.

Yep

Could suggest some of the other one people have told me from the Berlin catalogue (may or maybe not true)

Make one of those well techy superbike stands instead. You don't change tyres enough to warrant loads of fancy stuff anyway.

[_Stretchie_]

Cheers guys,

You don't change tyres enough to warrant loads of fancy stuff anyway.

You're not wrong there Chris, last time I changed a tyre it was for a Raliegh Activator and all I used was a pair of spoons.

I've seen loads of different ways on the internet about breaking the bead, from placing wood on the edge of the tyres and then driving your car onto them to using a big vice, or using the side stand of a bike

I've also watched vids where someone messed around with a couple of tyre irons for ages and it sounds great for a workout but part of doing this is because I need practice making stuff, so I might as well make something that is useful to me.

I've knocked up an angle iron base with proper castors for my tool box, my smoker and coal basket for said smoker, catches and stuff for around the garden, fixed a trailer for someone but I want to do something that will make life a little easier and cheaper in the long run. Me and Squirrell have several bikes between us, I have two cars.

If I can make this and use it, I can understand where things could have been done better and maybe make a bigger one that I can do the car tyres on too (maybe not the Land Rover one though :D )

It's more of a learning exercise that as a bonus can be beneficial to me and my mates. It's got to be better than making a set of shelves

[yorkie_chris]

You still need tyre levers and sweat for this machine you post pic of...

[_Stretchie_]

I thought that big bar completely replaced the smaller tyre levers? These are all lessons I will have to learn, but if I don't do it, I'll never learn.

I will definitely give you a shout about the nylon stock though.

I've got a fair amount of box section at home but it's only 25mm x 25mm and got a small length of box that's 25mm x 25 internal so I could make the three bits that will move along the arms.

I might just tack up a mock version this weekend

[Wideboy]

as i said last weekend my bead breaker work perfectly, i could change the front with leavers but the back was ****ing ridiculous, my rim protectors (teehee) split (teehee) and ****ed the rim (teehee) so i have to re do it (not much work).

i really like the idea of the mojobar but i want to see someone using it on a bike rim as the car one looked far to easy.

also wouldn't bother with something to hold the rim (teehee), as YC has said, all i did was chuck a carpet tile down and used my feet the brace the rim

YC / Wideboy

Something like this you mean?

http://www.svrider.com/forum/showthread.php?t=121158

Oh and Chris, from your earlier post I had no idea what you meant about a superbike stand, so did a bit of googleing, do you mean the Abba stand 'superbike' stand? That looks cool

[TamSV]

It seems to me that, if your machine doesn't have a central post, you've nothing to lever that walkaround bar against.

You either need a central post + walkaround bar or no central post + 2 levers.

[Wideboy]

pretty much, as tam said you need something to leaver against and i'd say that guys design would hold up on one of those mojobars, especially with the amount of force that is needed for the rear

if i was to buy some mojobars (still not convinced) i would get a piece of inch ply, evostick or spray glue a carpet tile on it and firstly i'd try a bit wooden dowel as a spindle for the wheel. i would think it would eventually snap but i'd try it anyway as i have loads of that sort of shiz hanging about. Either screw it to the bench of put it on the floor and stand on it.... then gurn and most likely follow through

[yorkie_chris]

You shouldn't be needing all that much force if you get the bead properly in the groove all the way round.

If you designing one of these machines you should change afew tyres by hand to get idea of what's involved.

[Wideboy]

i bent some spoons on the rear but when i see vids like this it makes it look like no effort is needed what so ever... ignore the first half of the vid

Drat.

[Bibio]

do it stretchy. that thing looks the business. looking at it the stand off at the end of the worm-gear looks as though it was put there for a breaker arm attachment.

i want one and guess what i will be doing this winter :-)

A decent sized bench vice can be used to break beads and is also extremely handy for hundreds of other jobs. The thing in your OP is good for one single job so will spend 99.9% of it's time taking up space and gathering dust.

[Bibio]

yes but when you do go to use it you will be glad you have it as it makes the job easier.

i have a tool fetish though and just spent £240 on a tool for removing and installing bearing/hubs on VW group (fabia) cars as you don't need to take the carrier out of the car and it installs them correctly. i might only use it a couple of times but that couple of times will pay for it. it can be upgraded for £70 to fit other cars and will have to tool there when i need it.

[tigersaw]

I just break the bead with a spade

[_Stretchie_]

I ended up going out on the bike for an hour or two on Saturday and came back 9 hours later.. oops :D

Then Squirrell came around, we all ate and me and Squirrell went to the pub so nothing happened about this on Saturday.

It's now Sunday and our Squirrell Hunter wasn't very well and ended up going back to bed for a lie down so I used that as an excuse not to do any work and I had a cook to get on the smoker but I did get around to looking into this.

I got the old rim out, covered the edge with some split hosepipe and my spare wheel and looked at it all

http://i76.photobucket.com/albums/j11/Stretchie_/Bikes/IMAG0237.jpg

But this wouldn't really give me as much practice cutting and welding stuff up so I ended up doing this

http://i76.photobucket.com/albums/j11/Stretchie_/Bikes/IMAG0242.jpg

Then rested a wheel on it

http://i76.photobucket.com/albums/j11/Stretchie_/Bikes/IMAG0241.jpg

Just need to sort out the grips for the rims and more importantly the base for it and incorporate a bead breaker. I have no idea if it's strong enough but there is only one way to find out. I'm just enjoying making something, and I have some wheels with tyres on them (thank you Thundercat) that I can have a go with when I buy the irons or tyre bar or whatever.

Been fun so far

[yorkie_chris]

Probably not strong enough to just lever off that inch x inch to break beads unless it is some sort of G clamp affair that supports underside.

[_Stretchie_]

Cheers Chris, all comments are greatly received. I wasn't convinced myself so thinking of welding some additional strutts from the arms either to the mounting pole or to the base when I make it.

But if it's not enough I can always re-make it from thicker stuff, at least then I'll know what I need and how much.

[Wideboy]

Coooooool!

There's a useful comment

[speedyandypandy]

Still hung up on this look right look left thing :smt100

Make one that's foldable, small(ish) and easy to bring along in the van and you might have to patent it and sell them, after you send one to me for free so I can test it and write a good report on it offcourse:rolleyes:

[_Stretchie_]

Good try our kid, good try

[yorkie_chris]

Thinking about it I would copy a commercial machine. Mount your doofer on a spinny base... have a heavily built C section between the bottom bearing and the edge of the tyre, use this as leverage point for an arm type bead breaker. Have something to fold/bolt in place like the lever point on a commercial machine... you break beads then rotate it by hand/with assistance.

[Dabteacake]

For breaking the bead could you not get two sections of scaffold pipe weld a flat plate to each about 3" wide. Hinge them at 1 end and then use a ratchet strap to pinch them together?

Almost like big scissors but with a flat surface for the tyre and the ratchet to take the strain for pushing.

A little bit further on this too. If you have it height adjustable you could lower it to take the tyre off aswell. Set it lower with the ratchet holding it shut but not fully weld a big socket to an old sprocket carrier and turn the wheel against the plate with a effin huge breakers bar

hope this makes sense lol

[yorkie_chris]

If you make the poles 3' long or more you won't need the strap just arm power will be enough for the bead.

[Dabteacake]

I was thinking to hold the arms in a position to give the necessary angle to remove the tyre as you turn the wheel with the Sprocket/Socket setup

[Spanner Man]

Good morning all.


An interesting thread this. I'm all for making my own stuff, instead of buying it. (You should see me 'workshop stands'. Heavy or what!) :D
I would add braces from the arms to the central tube. Rigidity is the key methinks.


Cheers.

[timwilky]

Good job your time costs naught.

For the time/effort and compromise needed to make your own, I would have opted for an off the shelf (http://www.ebay.co.uk/itm/Sealey-Tools-TC965-Motorcycle-ATV-Bike-Motorbike-Mini-Tyre-Changer-up-to-21-/140846938805?pt=UK_Motorcycle_Parts&hash=item20cb21bab5).

How much do you reckon that will actually go for Tim?

I love this forum...always adding to Dans wish list :rolleyes: :smt040

Yeah, I'm planning on doing that. To be honest I'm thinking that I'll need to make it out of thicker box section but if it copes as it is then great.

I know what you mean mate, but the main drive behind this is that I have just learnt to weld so want to make something myself.

The tyre changer was just something I thought would be use full and is a happy by product (providing it doesn't fall apart)

Yeah....I like yours...homemade is best :smt104

[embee]

Interested to see how you get on, I've pondered doing the same myself (because I can etc....).

You'll invariably get stiffer structures by bracing as you discussed rather than simply bigger section material. What you will find though is just how much pieces move when welding structures, you can line ends up and as soon as you do the first weld somewhere else they are suddenly 1/2" apart! All to do with expansion/contraction and yield..............;)

You'll soon get to thinking about the order in which to do the welds to minimise the effect or allow it to happen without causing critical dimensional issues.

Similarly, usually try to leave drilling holes until after the welding is done, positions will then be correct.
