Thread: Bearing Sources
25/05/2018 20:14:58

Many thanks Bikepete, I've measured the shafts and they are 17mm. The 51230s are 1mm thicker but that shouldn't make any difference.

Some ordered already.


Thread: Are we Luddites?
25/05/2018 20:11:48

I can remember reading some old Model Engineer mags and many of the letters were bemoaning to use of electic powered lathes, "it just isn't real Model Engineering, what wrong with treadle lathes".


Thread: Bearing Sources
25/05/2018 12:54:43

I'm having great trouble locating some cheap thrust bearings with the identification 2903 for my ancient Graham Alpine mill/drill.

They are available in USA and Singapore but the postage is ridiculous!

Does anyone on here have any suggestions for where to buy 3 of them?


Thread: Are we Luddites?

I'd have to disagree about us being Luddites, we don't go about smashing machinery (usually).


Thread: Hijacked websites when searching
23/05/2018 17:52:09

Has anyone else come across this problem?

I've conducted a search for information on my Graham Engineering DM25 Mill/Drill and most of the websites that are returned on the search mention my search term but want to sell me earth moving or rock crushing equipment!

I'd like to fill in their on-line enquiry forms with spurious information but cannot be bothered to waste my time further.

Is there anything that can be done about these companies (usually Indian or Chinese)?

I'm not going to let it worry me!

It would be useful to know your approximate location.


Thread: What did you do Today 2018

Thanks Neil, for the threadlock reminder.

I used to have a large milling machine with 3 axis DRO which was magic but I had to downsize when moving house.

My present machine is a mill/drill and I've just bought a M-DRO 2 axis system that was delivered yesterday (Friday 18 May 2018) and needs fitting BUT; I'm away for a few days! Still, it'll get done later in the week.

Hello John and welcome. What are you REALLY going to use your lathe for???

Whatever it is, you are sure to find all the help and advice you need on here!


Thread: Where do modelers get their blue prints?
17/05/2018 08:12:21

The patent office (UK) are very helpful and not expensive but be aware that patent drawings can be very unreliable and often show details that are impossible to manufacture. Their sole purpose is to describe an idea or an improvement to an existing one.

Some drawings are very basic with little or no detail whilst others are very detailed but have features drawn incorrectly so as to not make life too easy!

Finally finished wiring up a single to 3 phase inverter to my newly acquired Alexander 3A engraver & diesinker. All I need to do now is get the motor to run! Am awaiting a call from the person I bought it from.


All now working thanks to Direct Drives, who supplied the inverter.

I've only run the motor briefly on a couple of occasions and now need the check that everything is oiled and greased with the correct materials, then I'll have a go at actually cutting brass to make a pair of nameplates for my Burrell Boydell engine.

What material have you used to make your centres?

Thanks for the explanation Jason.

Hello Roy. if I go to latest posts and go to the last half dozen or so pages, all the entries have Replies -1 and Latest Post with no name or initials.


 PS. perhaps it is trying to go back too far?

There appears to be something wrong with the forum.

Hope you managed to make the exhibition Neil and if so what were your impressions?


Thread: Hello All
13/05/2018 19:10:25

Hello Kirk and welcome.

While being more of a road enthusiast I must admit that I prefer standard gauge. There are some nice Hunsleta though!


Thread: Colchester student cross slide - what bolt threads?

The only reference to 3/8" X 18 TPI that I can find is 3/8" NPT (National Pipe Thread) which is an American standard.
