So would something like this work for the purpose?

[Outlaw]

Or would buying that be a bad idea? Just wanting to make sure is all.

Is a good kit for the smaller applications.

[Outlaw]

So I took a look, measured it roughly, and the axle size is like... 6-7mm, whilst the pulley is 2cm... the one I linked is definitely not going to work, I think...

[Outlaw]

I know this feels a little spammy, but is there any pulley removers/pullers that anyone can recommend to me? As I'm struggling to find one that could fit the bill.

The reason why I'm asking this is because the wiper removers look a little bit on the flimsy side, I don't have access to CNC, and the ball joint removers look... well, too small or waaaaay too large.

[Outlaw]

So I literally tried to do the two screwdriver technique, and that sodding pulley isn't budging. Like, I put my full weight behind it, and it didn't even move a centimetre. (thankfully the axle still rotates, as I'm easily the same weight as a heavyweight robot lul) So, I'm back to square one on it, meaning that I either do the vice technique like I do with the mounts, OR I end up buying a pulley remover and having it be way too big or too small haha.

I think I may go to Screwfix tomorrow and see if they have anything that could help me out.

Did you try heating it with a lighter like NAT suggest ?

You could try a risky way by cutting a slot out of the pulley

[Outlaw]

I don't have access to a blowtorch, and I don't trust myself well enough to cut into metal just yet. Like I said when Ocracoke suggested anyway, I plan on using the pulley as well.

[Roboteernat]

Have access to a lighter? its not a blow torch, assuming you are over 18, you can buy these for under a pound.
Otherwise a gas hob could be used. But be carefull!

Once heated you can prise it off using the 2 screwdriver method. My one i tried last night came off easily with theis method. Is there a grub screw holding it onto the shaft too?

heat will be your friend here,

Check out the last link, i think this will do what you need...

potentially something like the smaller one will assist, but may need to grind down the ends a bit to get the 'fingers' to sit under the pulley...

Potentially this could do it too and only £3...

Never really rated those tools, Me and my Dad try to remove a bearing with on of those and it didn't budge so we smashed the cast iron outer shell (as we had a spare one) and cut it off

[Roboteernat]

i would agree with you, but for low budget and something that should come off easily, i think they will do, hence the opinion the last link should do the trick.
The 3 armed types are ok, we use them at work, but not the best.

[Outlaw]

Well, after a lot of swearing, a candle lighter, two screwdrivers; one that was already bent at the tip thanks to a paint can haha, a wrench, and my good old friend of mine, we managed to get the pulley off of the axle. Hooray! Now just need to epoxy on more HDPE to it, then go from there.

But it does mean we're back on the right track, somewhat.

Also, thanks Nat for the idea with the lighter, worked a treat on wearing the glue out, and the heat expansion too.

[Outlaw]

So I'm pretty sure it's the same for some people, but the snow has definitely made it a little more... difficult, to say the least. Fingers crossed the weather is wrong tomorrow and I'll be able to get back to work on Ratatoskr... and I may need to buy more HDPE, but I'll get to that problem when it comes around haha.

But the pulley is now secure in the HDPE piece, and now I need to do mounts and trimming, before testing once more and then armour templating.

[Roboteernat]

glad the lighter trick worked for you. Hope the weather was good for you, im hoping tomorrow there is less rainy stuff so i can do some grinding and welding
