Hi and welcome from an ex South African.

Steenkamp:
Thanks for the welcome vtsteam, krv and Abraham. The mill has a 90 degree knuckle for vertical milling, no quill, just a knee for Vertical movement. The helical gears are still a bit above my experience level. Another reason to make another spindle is to increase headspace, fairly limiting factor on my mill. Another limiting factor is spindle speed, max speed on the current spindle is around 1000rpm, a bit slow for my small 3 mm mills i use for engines. Will try and get to a larger town in South Africa tomorrow to look for some bearings

Welcome.  Off note there is a guy on the SA Gumtree at the moment selling castings of a Steam-engine, if anyone is interested.  Rhynard, big fan of the Tom Seniors. :drool:  With the constraints we often face in engineering in general, I often find myself using taper rollers of the type used as wheel-bearings for trailers and Land-Rover differentials.  If your making from scratch you will have leeway on the types of bearings to be fitted.  Whatever type of bearing you use, I would advice to overrate to the point of ridiculousness, only my personal preference in doing stuff.  Make it temporary, when you master helical gears you can always fix the old head. 

A cheap fix would be to go to the junkyard and get a light truck front hub, cut off the flange where the wheel studs are and with two brackets and a precisely made spindle you can actually end up with a decent head.  Hubs come in different sizes and so to do milling machines, upper seal supplied only need a lower one and in some instances on really old hubs you can even use the axle as a spindle.  Not to say that this will be relatively compact.

Forgot to add that this would be my method of making a belt driven head with independent motor and mounting brackets.  Disclaimer: Use only relevant advice and ignore gibberish.

Off to make a furnace blower from a Hamster Harvester, good luck :dremel:.

Hi, greetings from the North East of England. I certainly recall a Round bed Russian Lathe which would be some 40odd years ago used by a 'night school' student at Gateshead. I had a RB Drummond and
Mk1 Unimat then

I found my old Drummond RB useful then. It went to a friend who used it for woodturning.

Enjoy!
