Re: Questions for making a home made tyre changer
 

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

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

Then rested a wheel on it

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

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.

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.

Coooooool!

There's a useful comment

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:

Good try our kid, good try

Re: Questions for making a home made tyre changer
 

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.

Re: Questions for making a home made tyre changer
 

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

Re: Questions for making a home made tyre changer
 

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

Re: Questions for making a home made tyre changer
 

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
