Fitting a baker block(HELP)

[fatty]

Ok guys this may sound pretty lame but anywho help would be nice!!!!
I want to fit a baker block there are some great guides on braizing them together etc etc but where the bloody hell does the cap tube enter the head does it come down through the suction line???
Also what is the best material for replacing the flexable tubing on the mach 2 I have found some stainless mesh stuff with rubber inside that opperates up to 10 bar is that the stuff??


Cheers for any help you can contribute :)

[fatty]

Anyone please??? :stick:

The cap runs through the suction. IIRC the block has a hole for .28 captube so if you're using something different you might need to drill a suitable hole for it.

Stay away from that hose. The thing you want is stainles steel hose. or you might be able to use some metal flex hose (Astroflex makes them) ment for vibration absorbers if you can find one in the right size.

Cheers for that I will hopefuly have one in my hot little hands soon so I can have a play with it :)

[fatty]

I was looking at this stuff??

LINKY (https://secure.thorite.co.uk/Products_O_D__3_8__Pressure_69_bar_349.html)

It will hold 69 bar but it has rubber in it so???

[hatemi]

Im pretty sure it will leak. Try some shops that sell hydraulics tubes etc. I got my stainles hoses from DunlopHiflex and they might have a shop near you aswell:) cost me around 50€ depending on the fittings I wanted it to have.

[buffarilla]

wow

[fatty]

Bumping for more help I would like to see what others use please :)

[fatty]

What about THIS ???? (http://www.flexej.co.uk/content/P7.htm)

[hatemi]

That might work:) But before you get any wait for a second opinnion from someone who has used it before.

[JSU]

yeah that kind of stuff works (corrogated steel) but it wont work for a cascade.

[fatty]

Cheers I am still looking for the stainless braid stuff without rubber inside hmmm :stick:

Has the hiflex got a rubber inner?? Didnt they say not to use a rubber inner?? I'm confused

[Russell_hq]

You might want to try the other hose they do:

SS Braid with SS inner Hose (http://www.flexej.co.uk/content/P12.htm)

Its a stainless steel hose with a stainless steel braid.

They do them with a brass stub pipe so you can braze your copper pipe to them, the SS braid will add extra strength.

Whats the price on that hose ?

[Russell_hq]

Got an email back from the company see below:

Part No. FSH.015.1500.PC.PC
Length 1500mm
Fittings End 1 - PC = plain Copper Tail,
End 2 - PC = Plain Copper Tail

Unit price based on 1 off £26.50 plus £18.00 packing and delivery

Lead time 3~4 working days.

looks good, although delivery a bit pricey

[Epsilon]

Yeah, but when you order 10 pieces (some buy-it-together sail) it isn't so bad :).

[Russell_hq]

yeah, just got another email back, the hose is rated to 74 bar.g
That is more than plenty for this application. so looks good.

The pressure rating of the hose is above that of the copper pipe.

1/2" hose rated for 74.0 Bar.g but I do not know the rating of the
copper pipe or its joint coefficient factor.


Yes you can solder 3/8" reducers into the ends.

[fatty]

£18 P&P where the hell you shipping it too lol think I may get that there on one I got quoted for was 36 plus vat plus 10 p&p

[Russell_hq]

Probably because they will courier it, that will bump the cost up. It is a really good looking hose though. With the copper ends u shuold be able to braze it on no problem

[fatty]

Yeah im drooling looking at it now lol hmmmm but I only need it around 60 cm's or 16" or someat otherwise pc panels wont fit on but may give em a bell tomorrow are you in the uk russell???

[Russell_hq]

they manufacture the hose for you and stick the ends on you want, all you do is fill out the enquiry form on their website and the guy will get back to you. I just filled in 1.5m as a test, im sure u can fill in 60cm or 61cm or 67cm or whatever you want :D

[hatemi]

Hiflex has got many different types of hoses to choose from. you can get all stainles steel or even acid proof(not sure if it's the right term to use tough) steel if you want.

[fatty]

Cheers mate I'm sure with all the hose places I have looked at I will find someat the first unit may just use the stock suction line looool I know its useless single walled stainless corrigated but hell I just want to see how it goes for my first unit then if it goes well I'll replace the suction line but I will think about doing it straight off :)

[fatty]

OK well I think I am sorted now have arranged for 2 x 16" long 1/2" diameter hoses with 1/2" straight copper ends only £12 per hose and shove em in the post tracked or on courier for an additional £6

he said it will take 40+ bar and do -60 with ease :) looks like the job do er just waiting a baker head wooohoooo :banana:

[Ssilencer]

How many BARs it needs to hold for a single stage? because I used stainless stell flex hose with stainless steel braid and this kind of hoses are not that flexible and with the armaflex insulation you finish with a really thick hose.
The one I used can hold 100kg of pressure, but the ones without stainless braid can only hold 5kg of pressure but they are really flexible stuff. On the other hand, I see some guys using the most common stainless flex hose.

[berkut]

actually braid makes hoses more flexible to my knowlege

[Ssilencer]

actually braid makes hoses more flexible to my knowlege

Much more stronger yes (5bar without braid, 100 bar with braid) but not flexible.

[chilly1]

For a mach replacment hose you can use a 3/8 inch gas flex. Or go to the automotive store and get an ac hose. And there is always teh stainless braided flex lines. for the baker block you will need to run the cap tube inside the suction and feed it into teh block be sure to attach it if the hose flexes too much it will pull out of the hole.

[fatty]

yeah I had thought about that my way around it was to swage out a bit of copper to fit over the thread then blow a hole in the side of the copper and braze the cap tube through the hole but run the cap tube around the outside of the suction line :)then measure it and braze the cpper to the block however I think I will just get a couple of you blocks loool

[chilly1]

My blocks are a lot easier to assemble.
