Torque required to engage handle

Recommended Posts

Hi. Long time reader but this is my first post. I have a LMLM. Amazing espresso machine and I’ve had so much fun using it. It’s my first espresso machine but I’m the kind of person who does a ton of research and is a perfectionist. So I’ve probably watched most of the videos on YouTube to do with espresso making theory, practice and art and read blogs by Matt Perger etc. ? I’ve owned the LMLM for 5 months now and can confidently say I can make a pretty damn good drink with some pretty good basic latte art. 
 

My only problem is that I have a shoulder injury and I find the handle difficult to engage in the group head. It’s not an issue with the machine as I’ve been down to La Marzocco offices in London (They are great) and tried their machines. Mine is the same. I’ve tried changing gaskets to see if a thinner one might make things easier. It makes it easier to get to 6 a clock but not easier to create a seal. You still need some torque to prevent leaks when brewing. I’ve been told that it gets a little easier over time as the group head and portafilter ears get worn, although we’re probably talking 1000plus coffees later, which is a long time in a home setting. 
 

So my question is, does anyone have any innovative ideas that don’t involve tinkering with the machine itself, that would make it easier for someone with a shoulder injury to engage the handle into the group head? ?
 

Thanks in advance.

A silicone rubber seal might help. They can be hard work initially but relax well. They are made for a variety of machines so it's  case of finding the correct one. From memory I found one for another make of machine on ebay.

Hello and welcome :)

I prefer a Cafelat seal on my L-R and find it 'softer' when locking the p/f in (if softer be the right word) but I don’t have to go over the top tightening it. I can’t recall having to that when I tried one out either, not that I am doubting you or LM!

I third a silicon (cafelat) seal. They're squidgier than the rubber ones so not quite so hard a stop to get a seal. Have you tried locking off the portafilter with your other arm?

Hi. Thanks. Tried that already. Tried both the La Marzocco orange silicone gasket and the Cafelat Blue one. Both were considerably worse than the original rubber one installed. The original is 7mm whereas the silicone ones are 8mm, so the handle stays even further from 6 Alcock but more importantly, for me anyway, harder to create a seal.

Thanks. Yes I tried the blue cafelat one. It’s definitely a different feel. It was harder for me to create a seal with this vs the original rubber one.

Thanks for the suggestion. Tried that already and the LM orange silicone one. They were both more difficult for me to create a seal vs the original rubber. Yes I tried the other arm ??. Unfortunately, that’s not much better and I don’t want to make it worse.

Hmm. Only other thing I can think of is getting someone to make an extended portafilter handle for you to give more leverage.

I am surprised they didn't try to sell you the KB90 with its #StraightIn portafilter ?

Thanks. That’s a good shout and worth a try. Maybe even something to slip onto the handle to use just for inserting into the group head.

Haha. I’ve had my eye on that one. The day that comes in a Home-style one-group machine, I’m ordering it!! That would be amazing!

That'd certainly be more aesthetically pleasing. Maybe have a word with someone like@Nicknak to see what's possible.

The cafelat one will probable ease with use. I suspect it's the heat as they stiffen up again if a machine isn't used for some time.

Not an elegant addition but a short length of 32 mm  waste water pipe should fit over the PF handle and be loose enough to just slip over as you need it. If the PF handle is quite fat a 38 mm WP could be used.   Both available in.black , white, and grey.

Have you tried using both hands and perhaps standing closer to the machine to reduce the stress on your shoulders?

Thanks. Yes I’ve tried that too. I’ve probably tried every way of engaging/removing the handle but all of them affect my shoulder, if not straight away, then a day or two later. I’m going to try the suggestions put forth by others if either using a waste pipe or get a carpenter to make something suitable.

I had another thought and wonder if you are aware of anything that might be damaged long-term by using this technique - I could put the handle in and then firmly but carefully hit the handle with the heel/palm of my hand to effectively hammer the handle into place. Same thing to remove it. Obviously I’d be careful and use short movements to minimise any vibration. If I did this, do you think there’s anything that could get damaged as a result. Good or bad idea?

I am not sure you’d be able to judge the tightness and also it could loosen your carefully prepared puck.

I was thinking something similar. Get the handle in then lean on it with your hand, using your body weight to lock it in - don't know if this makes any sense?

Hi everyone. Just wanted to say thanks for all your suggestions. The carpenter had some waste pipe on him and filed the edges so as not to damage the handle. It’s about 40cm long and I just slip it on. So far, so good. It’s much easier to engage and remove and at times I also lean my body weight into it. It’s a little harder to judge how tight you need to go, as you lose the feeling you get when physically holding the handle with your hands but I’m sure that will get easier quickly. So fingers crossed, no more shoulder problems. Thank you! ?

I tend to see a bit of softening on our LM PB silicone seals at around 3 months of use. Or roughly 12,000 shots per group.

I do go for the 9mm ones as they lock tight with more ease than 8mm so were barely locking the handles in at all these days.
