No, the bolt ends are left as is. And no recesses for the bolts in the middle block. I thought this would allow the block to conform to the workpiece more freely. (Another lazy man's excuse.) ilkka

I am aware of the limitations of this way to hold workpieces. My mill is Proxxon FF 230 so I really cannot plunge into metal with it. Well, as blocks with some holes is good so blocks with more holes should be even better. So I drilled and tapped twelve more. Now I can hold circular pieces as...

Thank you for your kind comments. I have yet to use this device but your comments suggest it might be useful :) The jaws don't have tenons as I thought it would be an advantage to be able to adjust the jaws to hacksaw-sawn workpieces. (Or was I just lazy?) The screws of the moveable block are...

Inspired by this I made my own simplified version of a wide and low vise. It is basically three steel blocks with some holes. Very easy to make. ilkka

Looking forward to see (and hear) a video of you machining.

Thanks guys! I'm glad you liked the idea. Actually, I got the idea from that particular tool mount. I could even wedge it in the tool post for the relief angle, but I could not get it vertically right to get the disc centre at the end mill centre. So I made my own adapter. Originally, I...

Well, I know it may not make sense to sharpen smallish endmills. But if we take it from the hobby point of view we don't have to think how productive we are. So instead of making a new engine one may get a kick out of sharpening a dull end mill. I have a small Proxxon PD 230 lathe with some...

Not knowing what a "cold turn method" is, I'll tell my story. I made a piston ring from ductile cast iron for a Super Tigre 40 glow engine. The diameter is about 20 mm and cross section 1x1 mm. I got a bunch of odd shaped scrap pieces of ductile iron from a local foundry. Free :). The material...

I really enjoy this thread. /ilkka/

Thank you again, Bernard I think I'll change the gib for a brass one some day. My cross slide has got four screws: three ones with locknuts for adjusting and one for locking. -ilkka-

Thank you for your opinions, guys. Bernard, I was referring to all three slides (ways, cross slide and compound slide). I am using the compound slide for taper work only. The reason is that I noticed it is seldom parallel to the axis of rotation. The degree scale is too coarse to set it. Now...

How often do you guys adjust slides and gibs on your lathes? I have got a Proxxon PD 230 with a milling unit. I think I have to make some adjustments after every 20 h of machining. Is this normal or do I have a low quality machinery? Or am I just picky? I'm trying to have all sliding parts...
