Lapera DS second edition update

#1: Post by **baldheadracing** » May 19th, 2022, 9:00 pm

Thomas added some major new details about the second edition in his blog today. We're starting to see what the price increase from the first edition can bring, e.g., 316 stainless steel instead of 304.

ETA: Other changes and the build process are on IG at: https://www.instagram.com/laperacoffeemachines/ Some of the other changes mentioned on IG so far:
- revised mounts for steam and hot water valves (also sent to first edition owners)
- better finishing for components like the group top plate
- stainless steel castings replacing some chromed bronze castings and chromed steel parts.

What a ride the Lapera development has been. Not often do we get to have such an intimate view into the development of machine such as this. Thanks for sharing the link! I hope this gives the machine a bit more exposure.

316 stainless steel boiler construction update today - he has hired a welder:

Compare the 316 HX pipe welded to 316 cast group mount to the 304(I believe) assembly in my early machine in the prior post:

Thomas' updates are a pure joy to read.

The sTIG is astonishingly good...

Are there any updates on production of this machine? The build quality is amazing!

I would love to see a video of it pulling shots to show the flex of the frame, if there is any.

The second edition is shipping now - best place to see updates is on Thomas' Instagram: https://www.instagram.com/laperacoffeemachines/ and the blog: https://lapera.ca/blog/ - I try to only cross-post what I think people might find interesting, so I didn't cross-post the last two blog entries which were on some of the changes to materials, hydraulics, and steam wands between the launch edition and the second edition. Note the list of changes isn't complete, e.g., the group in the second edition takes E-61 shower screens instead of the launch edition's clip-on screen, as used by many vintage lever groups. (I haven't decided if I will get my group modified.)

As for flex, everything flexes, but, if I'm reading my dial indicator correctly, less than 2/100 of an inch at the outside edge of the group on a dry pull

:

Note this is in reference to the frame towards the front - the bottom of the Lapera's wooden feet have 3mm of silicone which ETA: do not compress appreciably. I repeated the reading with the dial indicator base on the counter and the maximum deflection was unchanged; it just added couple thousandths of noise at the start/end when I put/removed my hand on the lever. would compress a bit. (More on the feet: https://lapera.ca/in-praise-of-lrf/ ) Also, please excuse the mess, the DS is waiting for me to finish installing some of the upgraded pieces that were made for the second edition that were supplied free to launch edition owners. The machine has been neglected for a bit, as lately I've been getting a couple old Olympia's going

Thank you, that is very little flex, only visible with a dial indicator! Thank you Baldheadracing.

Another question; are there rollers on the group head lever to piston rod interaction?
