Looking for information about the castings of older Haas rotaries. The early HRT7/HRT9/HRT160/HRT210 models.( the earlier Black and White bodied ones )
I want to drill into the casting and install some threaded holes in strategic areas and would like to know if I have to disassemble the whole thing to do so, or if I can get away with my plan without doing so and not getting chips in the works.
I know the bodies were/are castings, and machined to accept the Worm Wheel/Worm Gear, bearings, bits, baubles, and platter, but am not sure just how far they went in doing so. Are the corner areas still largely solid? If so, by how much?
Searching for some time now has revealed no real information, so I'm wondering if some brave soul here ever pulled one apart and might have pictures from the endeavor.
Thanks.
The closest I have come is this video ( of a newer HRT210 ) at 54 seconds in, but still really doesn't show much of what I seek.
