After you print all these new parts and accessories take them down to your local Cerekote shop and get them coated in a contrasting color to really add a pop to the Robot.
Thanks for the tip on using the flathead screw driver. I was struggling so badly and almost gave up but was able to unscrew it when I had the flat head screw driver in... still wasn't easy but got there eventually!
Nice work, your solution seems very good! Im going to look at your other robot videos. A few questions- Is the bolt countersunk into the bracket? Did you try heat to break down the lock tite from the original stainless piece? Is the articulated metal sleeve over the pressure line necessary? You’d lose the pinch protection, but it seems like increased flexibility would be a big plus. Maybe your bracket could incorporate a tube guide into the head?
Yes, the bolt is countersunk. You can view the model here and spin it around in your browser to check it out: bit.ly/CafelatRobotGaugeBracket Click the tab on the bottom called "Subassembly" The pressure line tube is a tricky (unwieldy) thing. It might be fund to try a smaller diameter tube with more flexibility too. Yet, it could get jammed where is comes out of the Robot body. Each idea sounds good until ... you actually try it.
@@JohnMichaelHauck thanks for the reply John. I thought about how much work it must have been to create that model in cad. You’ve done some great work!
Hey, have you seen a video of anyone disassembling the pressure gauge online, you mention people discussing online but I've searched for hours and not found anything. I'd love to use this model for my gauge support but I'm not clear enough on how you're describing the disassembly and I don't want to break it!
Beautifull. Thanks for collecting all the solutions and sharing yours. Do you have any suggestion about the disallignment between the gauge and the flexible tube that seems to happen after the modifications in the pictures?
Seriously though... The actual tube is a Legris clear plastic tube from Parker. While I do not know what material it is, my money is on PFA since that is food safe, can handle the pressure, and temperature. That tube does not become disalligned with the fittings. The tube is protected with a metal sleeve. The sleeve helps keep the tube from getting crushed between the arm and the body casting. The sleeve does not connect to the fittings, so it can be pulled away from the fittings by hand or by a tight bend radius. The best way to keep the sleeve from pulling away from the fittings it to reduce the bend radius and other strains on the tube. On a side note, some people report a clicking sound when nearing the end of pulling the shot. When I first heard it myself, I suspected it was the filter screen getting stuck in the basket. It turns out the clicking noise on my machine is the ribbed metal sleeve scraping across the body casting. I hope that helps.
@@JohnMichaelHauck maybe an idea to avoid the sleeve to be not alligned can be fitting it with a sort of metal ring that keeps the two parts tight together?
@@gabrielevassallo3438 Finding the right fittings and tubes that are food safe, can handle the pressures and temperatures, are flexible enough, cost the right amount is a dizzying task. I think Paul Pratt did a great job on this for a pressure monitoring "afterthought". Another option is to dispense with the sleeve altogether and then maybe select a colored tube for looks, like green red or blue. ph.parker.com/us/en/fluoropolymer-pfa-tubing-fluoropolymer-pfa-tubing-1
Are willing to print out this and the washers for a fellow cafelot robot user? I love ur design but 1. Don’t have a 3d printer. And 2. One company by me that prints have a $100 min order.
I just quoted this at MakeXYZ.com The cost for one is $14.90 including shipping (I am in Michigan, USA). The cost goes down a lot for multiple quantities.
@@JohnMichaelHauck Thanks! this helps a lot. Thank you again for taking time out of your day to create great high quality content and for helping me out.
Guys don't do it. It is a very nice bracket,but pressure gauge not meant to be removed from the original bracket. Just damaged my pressure gauge. Try to modify using the original bracket.
This is a fair warning. Clearly there is risk in any modification, and this is no exception. I would not go so far as telling people not to do it though.

Hi, I like the bracket. The model of the Cafelat Robot you are showing in the video, is it also available for download?
The Cafelat Robot 3D CAD model is public and accessible to everyone here:

This is wonderful. Thank you!

Hi, John. Interesting. About the nut inside the fitting, they make thin-wall sockets that may fit inside the fitting. What size is the nut?
The nut is 11mm.
The inside diameter of the fitting is 14.5mm.
@@JohnMichaelHauck - Amazon carries them. Search "11mm thin wall socket"

How to modify using original bracket?
I also destroyed mine during disassemble as Paul uses a permanent lock thread. New gauge, all good. But I am pretty handy with tools and machining
