    My new Graduate lathe is in very good shape for its age - being a 1966 model that has lived 22 years in a school then taken early retirement in the 80s, but it’s looking scrappy and there are a few areas I want to address.

    Firstly the paint is mainly complete but chipped and covered in what looks like glue but I think stems from another problem.

    The spindle bearings were replaced and I don’t think it’s been done quite right as I decided to rev the machine to max speed (2000rpm) and it showered me and the floor with grease. The bowl turning end bearing cap leaked grease badly. I think sawdust has clung to the grease and become plasticky over time, causing the mess on the lamp and paintwork.

    The bed is rusty and could do with brightening up - an easy job, just break out the scotchbrite pads.

    The chisel rack could do with some fettling to make it work better (Harrison supplied wooden racks to sit under the bed as an optional extra)

    I also want to make a lamp stand boring attachment and possibly a sanding table for the end as I have a 14” faceplate for it, as well as a tool rest for metal spinning.

    I have begun with sanding, filling and painting the spindle cap, polishing the bedways and making a start on the lamp.

    As it turns out, the lamp is an incredibly complicated and robust, over engineered piece of British manufacturing. It’s good though! I’ve got another one of these in England with my cousin who’s going to send it over for my lathe, so good to get some practice. They’re heavily built things.

    The wiring is shocking inside and will all go. Gaffer tape and bathroom sealant :vsad: A new switch will be purchased too. I can’t for the life of me work the British patent website, but thankfully the Aussie one is much simpler, and these lamps were patented in both nations. I found some very useful technical drawings for the lamp base.

    I did all the painted bits for the lamp today in the sandblaster, then brushed the bits which need to move, pivots and threads. Off to buy a new switch for the control box now, hopefully I can find something suitably robust.

    I still need to wire brush the springs, being layered they have allowed a bit of sawdust and moisture in over the years despite the shroud.

    The actual lampshade and top bit came up well. The top bit will be hammered silver and the shade black with white internally. The arms will be hammered silver, too. I’m going to miss that sandblaster!

    $4.50 later, this looks much better. Now to get some sheet metal and make a backing plate to cover those holes :)

    I got all the bits I blasted into paint today. The hammer effect can was playing up but overall the effect is okay and a much better look than it started out with. I have yet to spray the white inside the lamp and reattach the bhi sticker, but so far it’s looking very pretty indeed! Can’t wait for the rest to be done now!

    I decided to try and solve the grease issue today too. This was successful and messy. It’s been very overgreased in its time and dare I say too light a grease. It splashed me in the face when I ran her at full whack and looking at other lathes, I decided my bearing cap on the bowl end wasn’t fully in place. It’s all in bits now.

    The spindle end closest to the tailstock was okay - grease a little old with that characteristic smell. The bowl end not so much. Black filth everywhere. A job for another day.

    Back to uni tomorrow so I’m taking another crop of bits to be blasted/brushed. Not much time left, a few weeks and I’ll have that privilege taken away. I think I’ve made good use of it though this year - four vices, an entire pedestal grinder, various bits off the Bantam and Fobco and a few garden tools bar all this latest stuff!

    Machines just don’t feel like they’re mine unless I’ve had them in bits and rebuilt them!

    I was hesitant to post as it’s more a metalwork forum but all the processes are metal/machine related and by the amount of other off topic material on here, I figured it’s probably of interest to some people.

    Switchgear cover removed and blasted. My plan is to paint this (and the start/stop switch) in gloss black like I have on the Jubilee grinder. Little touches and all...

    It sits right on the ground level of the lathe though and it’s taken you’re some punishment it would seem - thankfully it’s holding together, so I’ll just have to be careful in future. There was rust in the cracks so it’s old damage.

    Felt like doing piece work wire brushing all these little arm linkages. I wire brushed the acme thread too, there was loads of deeply ingrained crap in there. The swivel for the lamp needs painting silver and today I have to work out how to get the springs back on, not looking forward to that!

    Got the lamp base back together today - man those springs were hard to put back on! I split them into their layers and even still they were a tremendous effort to slide back into place. Still, there’s no chance of them breaking free now, which is good. They’re hidden by the cowling at the base. I’ve rebyilt most of the lamp, I just need to rewire, replace the name badge and make a new surround for the switch from some sheet aluminium I found yesterday.

    Shifted some serious grime off steel parts for the lathe today. Years of grease, glue and oil were brushed away but not without difficulty. The first pic is after one hard go against the wheel. I got some bits for the carriage done, two faceplates (3” and 4”), the dovetail chuck and the screw chuck.

    Very pleased to find this rare item for the lathe in the box that came with it - it’s the tailstock adapter for turning lampstands, deep boring. Most of these got lost as they bear no markings of belonging to the lathe. Feeling it slip onto the barrel and lock into place was very pleasing indeed, especially once all the glue had been cleared out of it.

    I decided to paint the start switch and the fuse box door in black like my other Harrison machine. These look good to me! Another coat of black enamel and they’ll be good.

    I also spotted this e stop box for sale, and recognised it as the same design (MEM manufactured) as my start switch. I may replace the mushroom with something a little larger and fit it as a kick stop lower down on the lathe, keeping in line with the aesthetics of the original! Another one rescued from the ‘vintage industrial’ shop to be put back into use :)

    The switch arrived, very impressed with postage it only took a day! That’s private seller with courier pickup, very good.

    As usual with these vintage industrial things it’s had the clearcoat treatment, poor switchbox. Might go for one last victory run on the blaster tomorrow before the workshops close for the year! I will mount this close to the ground and maybe make a bigger mushroom to kick in case of emergencies.

    That’s the stop switch restored.

    I ran over the screw heads with a file and then a hacksaw blade to clean (and lower) the slots. It is beginning to look factory fresh which is the goal. I had a test fit of it on the machine and it really will look the part.

    Lots of work on in the world outside the workshop so I’m sorry progress has been stifled. Next step will be dismantling the bed and legs, we have a waterblaster coming in the post so I’ll use that to clean between the ways, then probably paint them gloss red, keep some consistency with the Bantam. Three 600 group machines in a row, it’ll start to look like a showroom!

    @R-D-R I too have recently rebuilt one of those lamps. Mine is held on with this banana shaped steel frame, not sure if Harrison made this or Brookhirst Igranic.

    Either way, it looks the part and not something that has been adapted to fit.

    It’s very heavily built for what it is. Nice welds too.
