Tool review / Die holder part 2

[@bostedtap8399]

Excellent idea on using the four jaw jaws to set spindle angles. Thanks for sharing.

[@davidwhelan260]

All your inspection proves is parallelism to the opposite face, the key issues for these fixtures is the accuracy of the angle ground to the adjacent face ( square or 60 degrees ) and concentricity of the seat of the collet to the ground faces. ARC Euro trade supply a superior product for similar money and great customer service

Great conclusion to the die holder project, Alan!

Cool work sir 👍👏

I am dubious, are the untapped holes 9 or 10 mm If the through holes are not 10mm, these blocks cannot be bolted together! Regards, Matthew.

Hi Mathew the holes are just over 9mm and the tapped holes are M10 so you can bolt it to a tee nut with an M10 bolt to hold it to the mill or you can bolt the two together with 8mm nuts and bolts

@@enotsengineering Originally, 321 blocks had through clearance to allow them to be bolted to each other, the drilling out to clearance was omitted in the cheap knock off's to save money. I wouldn't buy them if you can't bolt them together! John Stevenson saw this and had the ones that are made for Arceurotrade made properly! Regards, Matthew
