Rob Id like to ask about that  taper attach .   what  type of steel and did ya harden it ? ...  i can use one for my Sb 10 heavy lathe   so if ya have an extra one send it my way .   we can trade something .. but with your talent doent look like ya need much ....

What id also like to know is when ya add a taper attach one  on a lathe that doenst have fit for it  do you need change the lead screw  or make attch to accommodate?
thanks

Hi Kenny , 

What steel do you have ?  any thing will do just cut it up and weld it together . I used plan old HR and  CR mild steel . 




Weld it and cook it at blast MK5 until black and crispy   ,,,,,,,,,,,,,,,,,,,,,,,,,,, and leave to cool .




I changed tack part way through the build and extended the main bracket to accommodate my newly acquired at the time long cross slide . 

A few machining shots . 





And yes ,,,,,,,,,that was machined on a round column RF25 mill/dill   as was most of this project .  


I did harden a few parts , the slider block was case hardened ,so I did not have MS sliding on MS . cast Iron would have been a better choice for this part ,but after at least 6 years use its all good.


Gave it a wee clean of today ,




There is a series of holes along the back of the lathe bed that facilitates the TTA being bolted anywhere along its length . 


I think the SB TTA is of the travelling type   , it moves with the carriage , same as the Boxford lathe I think .  Should not be to hard to make
