Something like this you mean?

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

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

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.

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.

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

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 )

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

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.

I just break the bead with a spade
