Questions for making a home made tyre changer

[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!)
I would add braces from the arms to the central tube. Rigidity is the key methinks.


Cheers.

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.

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

I love this forum...always adding to Dans wish list

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)

I've seen them from £180

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

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.
