Hi Y C,

Like John Alexander I have an old Compact 8 (1976) and the olnly part exchanged is the cross feed nut. I got my spare from Austria (Emco Holz und Hobby). If you can't find a replacement part, it is not too difficult to make one. I did when making a topslide with longer movement.

Hi Chris,

using R8 collets will give you maximum height between milling machine table and the cutter. To use ER-32 colleets you need a collet chuck, this will reduce the maximum height between table and cutter compared to using R-8 collets. However each ER collets have a 1mm range, so you need fewer collets.

Regards

Thor

Hi Martin,

I don't have an Atlas lathe, and my lathe is not nearly as old as yours (from 1976), but I get a runout about 1/4 of your result using just the old MT3 centre. Measuring about 20mm from the spindle nose. Testing for play in the bearing is good advice, you may be able to adjust how much play in the main bearings.

I wish my workshop was as tidy as yours John. At leat I can see the floor of my workshop now.

Hi Peter,

I just got a similar milling machine (HBM BF25) with the same sight glass as yours. I e-mailed HBM and got the reply that this is not used to oil the gears. You can remove the sight glass and apply grease to the gears (there should be grease in there from the factory). When finished greasing just pop in the sight glass. Also on my milling machine the gears and splines make some noise.

Hi Ian,

There are several Yahoo groups about building your own machine tools. Here's a few:

multimachine

Multimachine-Concrete-Machine-Tools

multimachine_india

machinebuilders

homemademills

In addition there are several gingery_machines groups. May be you will find some of them interesting?

Hi Mike

For small angles may be this site will be helpful? I suppose you could use the same principles as a sine table uses to set the topslide accurately. Like this or this?

Hi Wolfie

Maybe this link is helpful? It is for a locomotive but I guess it might work for your engine.

I use pieces of such platters as small parallells or to protect the milling table. As you say Tony, they are accurately machined, and my harddisks seem to have a limited life span (so I have a steady supply).

I too have enjoyede Harold's articles on his website. It is in my Bookmarks list.
