Rob,

Yes, definatly I would be interested in drawings. But take your time doing the taper attachment.

I do like the way you put those graduations on. Very ingenious. :thumbup:

tinkerer:
You are doing a great job. I am anxiously awaiting to see how this is geared to drive the cross slide, if that is how this works.

Brass_Machine:
I agree!. That is some fantastic work my friend.

Glad you are back.

Rob.Wilson:
THANKS LADS ,,,,for your comments and interest

tinkerer ,your are correct , the cross slide lead screw is disconected ,so that it is free to move back and forth , when conected to the TTA by a link it follows the angle set on the guild.

next the slider was machined up from a lump of BMS ,, it was milled all over square ,then set in the four jaw chuck to machine a boss on one face, the the dovetail section was machine

then the corners were given a radius

then i case harden it , just to stop the guide and slide picking up as they slide across each other, both being of BMS, the part was heat up and the placed into the case harderning powder ,re heated and placed back in the powder to cool

here it is black and crispy after cooling,,the reason for letting it cool was so i could spot face and drill the holes for the three M4 grub srews,this removes any case harderning in this area,so i can tap the threads after harderning,,,if i had just tapped the threads first they would not survive the heat treatmemt.

after re heating and quenching,now a grey color and with a very hard skin,and the threads tapped

Regards Rob

getting there
