The chuck spindle is 4mt. I have a 3mt ER32 with M12 thread, and converter sleeve. The Machine Mart chuck/collets are a non standard form, so to be avoided. I bought a metric ER32 set with additional 1/8 and 1/4 collets.

 

John, according to MM catalogue its 3mt, ignore this bit I'm quoting the milling head taper.

I wouldn’t buy tickets too soon. Just on the news, there seems to be a surge in the Indian variant of Covid-19 up north.

Bedford and Northampton not looking good either, Bedford Council already muttering local lockdown.

ER 32 milling Collet chuck from arceuro with a set of collets is cheaper than MMbut with MM you one more collet but you may need to make another draw bar, currently cant remember mill draw bar thread.

Danni,

I have a CL500M and find it a useful machine, replace all of the gib strip grub screws with allen key type and get them 5 to 10mm longer so that you can fit half nuts to lock them as they will over time become loose, I have bought all the parts to convert my lathe to VFD, I've not fitted it yet as I need to modify my motor pulley and need to do that on my brothers lathe which under current rules I cant use, the reason for the change is for the mentioned high slow speed. I have made a draw bar for the chuck tube to hold a ER32 chuck in the tube taper for use with small parts. I didnt have a chuck guard with my lathe so I bought a cheap small mag base and a piece of Macrolon to make a guard stood on the compound slide.

I get all of my tools fromJB Cuttingtools.com, Jenny and her husband are very helpful, mine are a selection of 10 and 12mm shanks with replacable tips http://www.jbcuttingtools.com/epages/es461493.sf/en_GB/?ObjectPath=/Shops/es461493/Categories .

I have never used my mill as I have a mill/drill but do have the riser block and other tooling which have been useful.

Can I make a silly suggestion, buy an Amazon Alexa, assuming you

have WiFi, I use it more than my radio, just ask it to play a particular station, no degredation at all.

Thread: Aircraft General Discussion
02/05/2021 16:49:42

Today I've been behaving like the cuckoo from a cuckoo clock, the weather has been fair to middling and I've been popping in and out to see what the aircraft were I've been hearing, it turns out that Shuttleworth, I'm only four miles as the crow flies, have had their first Airshow today, I've not been to an Airshow for years so had a look at the Shuttleworth web site to see how much tickets are and it appears that you not only need a mortgage to buy tickets but you have to rent a piece of land as well, standing on my own land looks like the better option at the moment smiley

Thread: Boilers
23/04/2021 16:55:23

Gentlemen,

just picked up this thread after another session in my garage/workshop, thank you for your time, from what I read my piece of copper tube is adequate for the job.

The boiler design in the book has a 1/4" stay passing through both ends and the end plates are 2mm thick, it doesnt give the gauge of the tube though.

Gentlemen,

Thank you, I got the pressure from a book called Ellie the steam tram which uses an oscillating engine and the safety valve is set to blow at 75 psi so I used that as my starting point, I know mamod stuff runs on approx 30 psi.

Good afternoon gentlemen,

I'm currently having a culling session in my garage and have come across a simple steam oscillating engine as a kit of parts and also a piece of copper tube roughly 50 mm dia and i'm wondering if somebody can tell me if there is a minimum thickness for the tube thickness for making a simple boiler to produce 75 psi max.

Thank you,

Martin P

Thread: Electric Smart Meters
02/04/2021 07:46:48

Clive,

I'm with British Gas, my display crashed so rang them up, I was advised to turn it off for 24hrs, after 24 hrs we turned it back on and it was working correctly and that was before Christmas and has behaved since, it made me wonder if the meters were getting an upgrade.

Thread: Annoying phone calls

Agree with BT Gaurdian, had the system for years and never had an unwanted call, occasionally the phone will display the fact that a call was blocked which is easily deleted.

AS a type 2 Diabetic who injects insulin my licence is restricted to three years, I received my paperwork before Christmas as the licence ran out this March, I left it until January to go onto the Website to renew it but after a while trying to give answers that I couldnt give I gave up and filled in the paperwork and posted it, within a week I had my new licence.
