The Hobbymat MD65 lathe was made by VEB Prazisionsdrehmaschinen in the 1980’s and distinguished by the bright colour paint and the D-section bed.
I′ve owned this lathe from new, bought around 1982.

Have had this lathe for more than 25 years and it still does as good a job now as ever. For a 25 year old lathe it cleans up rather well and with careful care, adjustment and oil the results are still as good as when it was new.
The belt system on the back of the headstock is easy to access.
Note that there is no motor cut-out and so you can start the lathe by accident with your fingers around the belts and so make a habit of disconnecting the lathe from the mains before lifting the cover.
The 250W motor has ample toque for all of the spindle speeds that this machine has: 250, 500, 1000 and 2000rpm. Now and again it would be nice to be able to go down to 100rpm, but this machine is in it’s element at 1000rpm and 2000rpm.
The gears for thread cutting can be seen in the tray on the right, these are glass reinforced nylon gears and based on the fact that these are over 25 years old they are in quite good condition.
They do however collect a lot of dirt and debris over time and so it is best to brush them out and hoover them clean every so often. I run the gears dry and normally just have a set installed for fine powered traverse of the saddle.
In the image you can see the gear between the spindle pulley and the headstock. This is a small gear driving a much large intermediate gear set that is on a bearing that is adjusted up and down on the post and then finally engaged with the main headstock spindle gear by adjusting the position of the aluminium backplate that it is fitted to.
The intermediate gear reduction then drives in this case a larger black coloured gear that is fixed to the end of the leadscrew via a dog clutch. The handle for the dog clutch can just be seen disappearing out of the bottom of the image.
I have used this lathe over the years for model making and so it has to deal with metal, wood, gear cutting, thread cutting and a number of plastics. I will post pages on these subjects and the use of this lathe.
I′ve used this Hobbymat MD65 lathe for over 25 years and it still as strong as when I first bought it. The on-off switch gave up some years ago and I replaced it with a switch from Maplins, otherwise it is perfect.
I actually think this is a better lathe than one of the Mini Lathes in various colours from China. You can buy a secondhand HobbyMat for under £500 as of 2012.
- Gear cutting – a combination of the MD65 and Unimat 3
- Thread cutting with the MD65 – plus a modification with a handle to allow threads to be cut up to a shoulder.
Machining and Polishing a Perspex Light Bulb – with the hobbymat running at 1000rpm I use lots of cutting oil and ever increasing abrasive grit numbers to gradually smooth and then polish the perspex.
