Nice job. We shared this video on our homemade tools forum this week 😎

Some neat hand scraping on that surface plate. I find myself looking all around the scene in your videos. Lots of interesting extra information.

Fantastic project mate 👍

Thank you very much for showing your process; I bought some cheap imported collet blocks and now I'm curious (and able) to inspoect and probably improve them.

enjoyed the music 😉

Hi Michel, it all depends on the accuracy of the collet you use for this action, don`t you think? By the way, a friend of Job.

Michel, I think your sreaming tooling has to with "some" rigidity" issues. E.g. it's a small, flexible, machine, the stick out for the small boring bars is long and they flex below center height into not ideal cutting conditions. I also encounter this on a bigger machine but have found some tricks to reduce it or even get rid of it. Try to find boring bars with carbide shanks. They cost more (I paid 250 euro for a set of 3). Start with the tip of the boring bar a hair above center height, try lowering your spindle speed with the same d.o.c. (sometimes resonance is an issue), use a good cutting oil like Motorex (not affiliated by any means, just a happy customer), sharpen your insert with a diamond stone, and last but not least decrease your depth of cut in combination with a lower cutting speed. You should get better result with a combination of these actions. Maybe this helps. All the best, Job (ps, holding the grinder with a split clamping device? More rigid, no marring of the tool? ps2; Misalignment of the headstock is common for lathes. I correct the difference in diameter by displacing the headstock from the centerline according to a bigger or smaller end on the part. Bigger? The headstock should be moved half the error towards you so it cuts more to the end. Much easier than going for the theoretic ideal center of the machine. In the beginning start with an indicator in a collet in the spindle and indicate the pinole to the center for common work like drilling. Centricator is ideal for this...) Looking further I think your tailstock isn't adjustable. A movable center could do the same trick. They're sold as a kit and maybe as a complete item. The morse taper is not the ideal support to. It still can hinge under load. A tight plug with a center hole would give you more support)

I don't even use the lock on the tailstock because of that. Theoretically it can be adjusted but my cheapo pulls on the spline and changes center so I just crank it with the wheel and leave it at that.

Dag Michel heb je de slijpspil zelf gemaakt ?? Bij 5,15 minuut. Dankjewel

Why not use a press fit?
