I am in contact with the seller, and i will try to get an appointment on sunday to see the lathe, if i buy it, i will carefully test it and run it for a while before i decide what to do. maybe the attachable high speed spindle that Niels was suggesting isn't such a bad idea after all. The lathe...

We run the schaublin at work at top speed 3000 rpm most of the time, we use 5c collets when ever we can, we use inserts, and that require higher speeds How often do you pull your spindle out of the headstock? I do realise its not a straight forward job, but i don't intend to mount the original...

The lathe i am looking at at the moment, is from Danish Machine Company, i have only seen pics of it. i have used a couple of these old lathes at the beginning of of my career as a machinist, with a top speed of app 1500 rpm, and that was rather scary compared with a lathe with ball bearings...

I am about to buy a lathe, unfortunately the budget only allows an old lathe with bronze (or whatever material it is) main bearings. i am used to use a lathe with a top spreed of 3000 rpm, but i doubt the old headstock can handle this. has anyone made a new headstock with angular contact ball...

I have measured the rpm on the rotary attachment (well, i could infact count the lowest speed ;D) Lowest speed is 200 rpm, and highest speed is app 300 rpm, the motor is only 680 rpm and of course right and left switch Thm:

I have been looking at the motor, but there is no rpm written on it. i might be able to take a look at it next friday, while my son is practicing the saxophone ;D (not that i dont want to listen to him, but because he practise close to my work)

I can help you with that problem, i will gladly help you get rid of that chassis taking up space in your workshop, and unselfish as i am, i will do it for free (well almost ;D) I have the perfect engine for it http://efiminis.olicentral.com/index.php?topic=92.0

As promised some pics of the rotary attachment I haven't used it yet, so don't ask me how it works, we bought it just before Christmas, and i have concentrated on the main machine With one of these it's quite easy to grind the table on the Tacchella, it travels 0.5 X 1 meter

They are roller bearing rollers, you can buy them from a SKF dealer, 100 pieces per box Holt

I will try to remember to take some pics in the near future (tomorrow evening)

Sorry, i just saw i was too generous with the zeros, it was 0,03mm runout. our grinder came with a motor attachment, with r-8 collets, 3 jaw and a magnet + several other items

I just finished renovating a Tacchella 40L at work, lovely universal grinder, the table was out by 0,03 mm, not much, but far too much when the grinder are used to grind 0,01 mm air vents in plastic injection moulds. i changed all rollers, and gave the table a turn on the large grinder

If the tube isn't too long, fill with water , put in the freezer, and bend while frozen. I was told it is how they made the frame for the Lotus Elise Thm: Holt

I am sure once the postage and customs to Denmark is payed, it would be cheaper (and more fun) to make your own set

Thanks every one. I have downloaded mklotz's program, and it seems i could do with a 72:1 worm gear. if i can't find one, i guess i have to make one eventually, lets see, i am not in a hurry. ;) Holt

I would like to build a combined rotary table/dividing head, for the RT a 36:1 worm gear would be perfect (10 deg at each revolution) but most dividing heads use 40:1 worm gears. What would be the best compromise? I can't remember how to calculate divisions, i haven't used it since technical...

Hi Anko Very nice looking boring head, sorry about your dovetail failure, would have been nice if it had turned up as you had intended. For the adjusting screw, its only a matter of getting use to it, and it will work just fine Thm:

If you make the cutter in the way you describe, there would be a radical change in the cutting angle with different overhang, and you simply don't know how your cutter behaves when you try a new overhang, like the lathe, if your center height ain't right it wont matter as much with a large...

You can get away with making the hole in the center of the flycutter if you make a cutter bit like this Works really well on both surfaces and in holes

It is like the center height of a lathe
