Just a note here, it's easier if you don't forget the routed section in the bottom, or you will need to set it up in the milling machine.  :doh:

Real artisan stuff Ronin!  Beautiful job mate.  Is the machine shot ready yet?

Thanks guys, my wife likes the paddles too.
I don't think they are anything special, but after a while working with timber, it wasn't hard.

I think it's shot ready Brett, just need a safe power point = not in this house.
I want to plug it in (to fix any leaks that might appear) and get it working, or fix problems.

Update time

Took the machine to Espresso Mechanics to test and tag the machine, and of course check my work.
Very helpful bunch of guys here is Brisbane, Mark has been looking at the GS for me and found some mistakes and differences in the wiring from original. He has contacted a number of people to get a the original wiring diagram and has possibly found one from La Marzocco in Italy who are apparently happy to supply it, but are on hols till the end of August.

I think I'll wait to see how it was done originally.
I really cant speak highly enough of Mark at Espresso Mechanics, very helpful and knowledgeable. He also has the Slayer form Cup Speciality Coffee and the Synesso from Pourboy in the shop ATM, so the GS is in good company.

Apparently some guys from Toby's Estate were in the other day and were impressed with my work, and asked if the boilers were original as they are so clean.

The timber group caps are not coming along as i had hoped. There are too many glue joins visually, but needed for stability. I've been looking at the handles Derrilex has made which has got me thinking about resin/ timber look group cap and taps. Time to investigate and speak to the man himself.

Thanks for the update Ronin.  Great to know that there is a good tech in town also  :thumb:

I can tell you that you won't have any stability issues with DX's resins.  I was shocked at how strong and solid it is!  Interestingly I think it is the same stuff some bozos used to seal cracks in my carport slab before concrete spraying it.  I had a play with the cured leftovers when they left and it seems similar.  Would this be the case DX?  Obviously theirs wasn't pretty colours but fairly clear in colour.

The "bozo's"  :laugh: normally use epoxy resin for concrete - or anything in the building industry as its generally more flexible than polyester

I thought this quote funny D.
I've been using resins for almost 17 yrs at work, mostly epoxy, because of the strength and durability. We mix it with slate powder to increase these properties. I have no expierence with these products in the building industry however, but everything I have read and sales people I've spoken to contradicts what you say here. I believe epoxy to be more expensive also.

Perhaps it's industry dependant.

Had a play with the GS today, long time between drinks.
I initially got this project because I had time to spare, but lately it seems I have none.
2 more projects which have had priority, firstly we needed a house, but purchased one in need of some work = time poor me. Second is my wife's 9mth project that is almost half baked now.

Anyway, got some leaks in places I expected, brew boiler end plates for example, and others I was not expecting, through the gasket between brew boiler and group heads, and an OPV on the brew boiler. Yep, a brand new opv that leakes like a hose. Steam boiler looking good and most plumbing good too.

Most will be an easy fix, hopefully I won't need to pull off the group spouts too.

High temp food grade gasket sealant may be the answer
This can be used on the threads as well

I know how your feel mate.  I pulled down my San Marino many many times to fix leaks.  It just seemed that you fix one, and cause another.  Take a deep breath!  Count to 10!

I used a high temp foodgrade sealant but I found it very messy to use, in the end I used the pink thicker plumbers tape.  Worked well.

That's the thing KK, I used sealant around all gaskets (both sides) and bolts. I looks like its leaking through the middle of the gasket. More investigation needed of course.

Either that machine is one in a million or I could swear that machine came from my kitchen counter, Im in Seattle back in the united states. Did you pick this up from Espresso parts by chance in the states?
It looks identical.

P.S. I still have some stuff for that machine lol...

Welcome Sky!  We've seen some left-field first posts but I think yours might take the cake!!  Welcome mate... Sounds like you're into some pretty high end gear.  This GS looks amazing!

So you wanna hear a story.....
If this is the same machine, And looking at it with the paint being in the same shape and the paddles as such.

I have a lot of high end gear in Seattle, A couple gs paddles, synesso stuff, vintage lever pulls and the new stuff too. If this is the same machine I found it in the back of a shipping container in the middle of the forest near Mt Rainier, Some Junkies had inherited a whole cafe setup from Tacoma. I was casually browsing through there stuff when I saw it. it was most unfortunate that upon seeing my smirk they doubled the price on me lol!

I took it home and messed with it, I put this machine on display due to its retro cool styling. never really turned it on for the year I had it, (did the sight glass leak? lol) a few years back I got super burned out on repairing / refurbing machines and sold it to a buddy of mine to buy a 78 VW bus and hit the coast. I super regret selling this machine!!! This is probably one of the best original condition gs machines I have ever seen or heard off. Paul Pratt has some beautiful restorations and there is a rumor that there is a brand new one sitting in a box in a basement in Seattle.but otherwise. PM me with any questions if this is the same machine.
P.S. Dont drop the caps!
Sky.

Hi Sky

Sounds like the same machine to me  ;D
Interesting story re the machine any more info on it?
Good condition for a 30ish year old machine when I got it, but the wiring was shot. It was crumbling in my hand when I touched it so, No I didn't turn it on.
It looked like the sight glass was leaking at some point, but not now it isn't  :laugh:

I don't regret you selling this machine, for what's its worth.
Paul Pratt has helped me with the restoration, Ive tried to keep any mods easily reversible eg. PID & SSR are mounted on brackets that use existing holes, and I changed the colour (have been in two minds with this tho as I like the colour it is, but it's not original) I was under the assumption that the yellow was not standard and the orange is not to my liking.

Group caps still in good condition  8) and I've made a mold to make replicas. Made a trial one which looks ok but needs a little refinement.

What parts do you still have? I'm very interested
