I watched the very same video and thats why I decided on the 24vdc unit that he had used.

Or a 24vdc wiper type motor unit that I'm building one from.

Danni,

My Machine Mart 4 jaw has no makers mark and is mounted onto a steel back plate the OD of the chuck and back plate are both 149.60mm dia, the back plate is 12mm thick and the recess is 3.55 mm deep and 99.90mm dia and the PCD of the three tapped holes to mount it on the spindle is 131.6mm dia.

The hole in the centre of the back plate is 32mm.

Hope this helps,

I will do that tomorrow if ok, bad weather and household chores means today is already laid out for me

Danni,

My three and four jaw chucks are both machine mart and they have three bolts to hold them on the spindle plate, I found that the three bolts have the same pitch but not the spacing, one bolt is ever so slightly closer to one of the other bolts and I've centre punch the plate and chucks to make sure they fit correctly.

A friend of mine had similar wheel for a trolley for his very large open crank engine and they had come off a bomb trolley.

I have a 20+ year old Black and Decker and a similar aged Red Deveil angle grinder both with trigger locks, I've never had an issue with them and they are still going strong.

The only NHS app I've used is the test and trace NHS Covid 19 app and that is since it cam out and all it records is where I go by reading the Q codes that I find so they can track where ive been which is care homes, retirement homes and hospitals and any where others have set them up, I also use the C19 app by ZOE, for my wife and I, which was set up by Kings College London where I send info about how we feel every day, if weve been tested and details about our jabs etc and how we feel.

Those of us who restore stationary engines build our trolleys using cast iron wheels from old barrows etc, a set of four wheels can now cost upwards of £60 to £70, as an alternative some enginemen make them out of large dia pipes to make the rims with a length of machined bar for the centre and smaller pieces of bar or flat stock as spokes.

John,

Thanks, I use my manual for detail, enough rubbish in my head without adding more by the way whose DRO are you using.

Martin P

Until I go out to my garage tomorrow I cant confirm the thread size.

Martin P

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

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.

Martin P

John Halfpenny,

May I ask what make your DRO is please, is it on the traverse axis also.

Martin P

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.

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
