I hadn't come across the combo ones before either. Not sure if they're 'new' or not. It certainly saved me a lot of extra fittings and adaptors, which goes a fair way to off-setting the extra cost. (not to mention the less fittings & joints the better 🙂

I had reason to open up my BZ40 as my Cigar controller blew Had a crema member visitor & all I could offer was siphon Long story short it turns out that the BZ40 has the very same dual safety & anti-vac valve fitted or looks very close KK

Anyone know where I might go to get some old style dome head bolts? Like this: Either style is probably ok - looking for a set of three. I had three different style of bolt come out of the group head :o

Yes, it was a genuine Bezzera part that arrived.... cheers.

Take them into a fasteners shop, not just any hardwear. Is there one close to you? Worsed case senearo would be a machine shop custom job, but I really think they would be off the shelf.

borat123

thanks guys. I've already been to coventry fasteners here in Adl, but they don't stock the old style dome heads. I'm trying to get a set of three the same. At the moment they have a different head on each of them. Yes, I'm happy enough to chrome them up but I don't have a set of three to work with... I thought maybe there was somewhere that specialised in vintage or second hand nuts & bolts. cheers.

Will something like this be OK http://www.probolt-australia.com/Products/Stainless_Steel_Bolts_Dome_Head KK

Locally I found a nice stainless steel bolt shop. They seemed to have everything I ever wanted and I could by 1 or as many as I wanted. 🙂 I found coventry fasterners locally here didn't stock much in the way of stainless stuff. 🙁

Lost posts sorry they are out of sequence. "I got some hard drawn copper tube and had another go at re-doing the bends for a new steam pipe. It was harder to bend but the thicker wall made for better curves with less distortion - I think this one is even better. Paid a visit to an aircon guy this morning who removed the old fittings, then silver soldered them back onto the new pipe. It will need a bit of filing to smooth off the solder but should look good when it's done. The oxy temps made a big difference compared to my Bunnings propane bottle... eh KK 😉 Then dropped it into the plater / polishers for polishing and chroming." Borat123 "Posted this morning.. As to the other bits you sent... Beans are always good ;D As to the two valves... One is a possible repair, the other was a complete write off and NOTHING to be salvaged. The mini anti vac, should be OK.." - AM "Glad to hear the beans are good 🙂 The parts are all yours - maybe good for a spare sometime...<br /><br />cheers, Stuart" - Borat123 "I have a confession to make... A horrible dirty little secret...... Those of you with weak stomach's, look away now.... :o :o It was cemented into place with years of caked on scale. Heating, penetrant, nothing would loosen it until the stillsons came out to play. Unfortunately they left their mark... But good news! The entire part in the pic is available new And bad news... The thread on the other bit from where it came was stripped too... but wait, there's more good news! The stripped thread on the other part was not totally destroyed; it just contained a heap of what looked like extra brass filling in between the thread, and only on a small section. I had a tap run though the first centimetre or so, and wallah, good as new! The moral of the story, get the decaling done first before trying to undo fittings.." - Borat123

There is another way it can be done Use a threaded stud and a hex cap nut KK

borat123

Thats a great idea! Thanks KK, I'd never thought of solving it that way. Would you use loctite as a way to permanently attach the nut to become the new bolt head? Obviously you'd want the whole lot to turn when trying to remove the bolt at some point in the future...

borat123

:o :o Ahh, my dirty little secret has returned. I knew it wouldn't remain a secret for long.... 😃

Was worth finding too ;D With loctite they are not all the same some are different shear strengths from just a help right up to get out the torch and long bar to undo me. I normally keep a couple of different ones depending on the task I am using it for. Most with the application of heat will soften if you need to get them undone in the future.

Ok, so I've been to Coventry with the original bolt and they matched it to 'Grade 304 St/Stl Hex Hd setscrew M6x35mm So now I've found a M6x40 stud. The extra 5mm being for the length taken up by the nut.... Do you think the thread on the stud is the same as the 'setscrew' above - I'm guessing yes if they're both M6 (?) And Coventry have a chrome plated dome nut that looks the part: What do you think? PS. Thanks AM, your latest masterpiece arrived in the post today 🙂

But what is the PITCH... 1.0 OR 0.75 The pitch is important and critical. Many assume there is just one pitch. But for many reasons there is at least two in the smaller sizes and can be more for other sizes. In brief a Coarse and a Fine thread and in may areas where there is a need for high strength, the option of a finer thread is used...

Thanks AM. Hmmm, just as I thought. I have no idea... 😃 😃 I checked their website and the 'Boltmasters metric coarse internal thread dimensions' pdf file, shows M6 with a pitch of 1.0. I'm not sure if this applies to studs(?) http://www.boltmasters.com.au/wawcs0142991/Technical-Information.html As to the pitch on the bolt from Coventry I couldn't find any more info. Maybe if I called them up or went back for another visit with the part number (6X35MG304SS), they'd tell me.

I seriously recommending that you source a stud with an allen key drive hole in the end This will allow you to tighten or when required to remove the stud I also recommend to use low strength loctite Apart from holding the stud in place, application of loctite will also act as a barrier & protect the thread from bad stuff growing on it over time / years KK

My boxes of parts are getting closer. Online tracking shows they made it from Europe to Guangzhou China.....

I don't know if this will help - EXHAUST-STUDS-Moped-Motorbike-Honda 6M with allen key drive end should be able to get them in Adelaide Just like these http://www.ebay.co.uk/itm/M6-x-35-STAINLESS-EXHAUST-STUDS-Moped-Motorbike-Honda-/380342307570 KK

Thanks KK, I'll check them out.. Fedex tracking is great - I can see my parts are enjoying the scenic route. Now they've made it to Singapore.

borat123
