Not actually machined anything , but I picked this little backplate up and thought I would give it a spin , had to take off the gaurd and safety switch , remove the gap bed , (never been off the machine) , took a while to get it up and on with a lift and pull hoist but nice to see it working ! Took it to 125 rpm,

I had to make a pulley for a Tom Senior mill.
I suspect a previous owner was hitting on the drawbar to eject the 3 Morse Taper horizontal arbor and missed the drawbar and hit the pulley.
It is basic stuff, but as a beginner it took me ages to make the bloody thing.

You are not the first to have done that and you won't be the last

That knowledge doesn't make it any less gutting when you damage something though.

Made a knurling tool. Got the plans for €5 from this Canadian guy. https://d-gray-drafting-and-design.myshopify.com/
Build it from the offcuts I have in the shed. The only things I had to buy were the spring and two good quality HSS-CO knurling wheels.
I must say it does make a nice knurl.

The brand is Integi. From Spain apparently.

Power feed motor is burnt out on the Bridgeport mill i acquired and replacement motors a fortune could get it rewound but contoller board smells fried too to decided to bin it all. An option would be a chinese power feed but one with an adapter for the shortened lead screw are a lot more money.
Decided to go down a different route still Chinese but using components i can easily replace , I worked out I need about a 120w 24v motor turning at 3000rpm to match the old motor usually £20 to £25
just had to cut the old motor off the input to the 8F housing its a wierd size 12.7mm
Then a simple case of machining an adapter for the scooter motor . Luckily theres a lip on the input housing and the outside is 4" lip is at 98mm so gives enough meat off a section off 4" bar i cut down, on the other side of the adapter is a recess the same size as the front of the motor so everything parallel
I found a small flexible coupling that machined out to 12.7mm the other end same as motor shaft
I think its worked out well add a speed controller and 24v power supply still under £100
Ive used this controller so easy to wire the forward reverse into the original lever that controls direction and has a bar on the front with adjustable stops

Many years ago I was contemplating making some feed drives for my manual Bridgeport many moons ago and as I searched around I thought why the heck am I bothering, why not just go the whole way and do a CNC, that was my very first retrofit

whats odd is 90% of a Bridgeport is metric ALL the bearings and shafts are I guess because designed by SwedesOtherwise known as 1/2"
