@@userwl2850 Trial and error is the best way. I learnt my lesson trying to drill stainless sheet metal. Killed all the Hss. 3/16 drills I had. It kept heat treating it trying to drill through it over and over again. Lessons you dont forget when you find solution. Love your set up with the tube holder and the massive hunk of rod. Steady rest has some mods too. Save the core for other projects. instead of making 300lbs of chips for the recycler. Hats off.

So many questions. How do you support the billet to cut the track for the steady and centre drill it? What's the ball park value of pieces of metal like that? (Typical) Do the customers want the cores returned? I've only just found your channel so sorry if you've covered this. What type of industries are your customers? Great interesting videos.

Big just seems to be getting bigger Dave - phew! Always beats me how you manage a perfect alignment when you change ends (gravity and all that)! That 6' long one with large bore has to have been among the biggest buggers - but then the 88" x 10" bore - damn. As usual, impressive chips. Suds look well generous. Usually find it hard to imagine where the finished work ends up when such large stuff. Go get your John Smiths!

Hey Chris.. they always meet up. Only thing that happens is like I said .. The bore gets smaller... not by much.. that's why it's best to meet up halfway. Going for a pint now 🍺🍻

So if the inserts are always pushing the trepanning tool in the same direction away so that the bore gets smaller and the core bigger, why arent the inserts set up in that way, that both forces cancel each other out, like for example if the entering angle of one insert is slightly different than the others?
@userwl28505 жыл бұрын
I like your thinking.. very intelligent. They are set so the forces do that.. works easy on short stuff but obviously there are limits. 👏🏻👏🏻

@@userwl2850 Thanks David for your kind response. I truly admire your machining accomplishments. One of my "accomplishments" working in a "job shop" that I still remember (and still have a NFG sample), I once had to cut many trepan faces on multiple parts around and over an existing 3/4" dia. that stuck out 2 1/2" inches in front of the intended trepan face of this lathe part. The trepan inside dia was to be from the shaft's existing 3/4 dia, cut to an outside dia. of 1/3/8", approx 9/16" deep.....into H13 material! The bottom insides of the trepan had to finish with 1/16" radii both inside and outside. I had to hand create/machine a tool holder, which held two custom created and custom ground "standard" carbide inserts... top and bottom. A round plunging/pecking tool with clearance for the existing shaft. The problem of course was the tightness of the radial clearance and fragility of the tool to accomplish this clearance. Coolant flooding of the tool and chip removal (pecking) was essential for success (Also many "backup" carbide inserts). The shaft dia. plus major OD and multiple face(s) of this machined part were all later (after heat treat) OD ground together square and parallel with each other within tenths, so that all surfaces fit into a precision injection mold of some kind without leakage or "flashing". BTW The insides of these parts were also a "bitch", as they had a relatively deep (1/14" ) and small (1/2") internal fine thread and "seat" inside the shaft, that had to bottom precisely for some kind of replaceable nozzle insert?
