Thx, for clearing that up. 'nother question if you do'nt mind - the threading stop hole (the hole at the front of the cross slide) is it the same size + same thread as the travelling steady holes. Sorry for badgering you, but your cross slide looks very similar to mine. Regards. |

Looks great! I made a similar plate for the top of my poor man's milling machine, and it works great. I'd suggest putting some bolts in the holes that aren't being used for clamping. Swarf loves those holes. If they do get swarfed up, I just use a drywall screw to pull the stuff out. |

However, you have now flipped it and your teaching me - what exactly is the whole for at the front side of the cross slide!! I presume your talking about the, to me, seemingly random empty threaded hole just below the front edge of my new surface plate on the top slide? |

My Myford ML7 has a slotted cross slide, but sometimes you need something a bit bigger - or maybe a lot bigger. See below for a plate that I made specifically for a between centres boring job, where two holes need to be accurately to size and exactly parallel - the cast iron sections are for a jumbo sized Bonelle cutter grinder. I think that this might qualify for the 'serious over-use of a ML7' award, but it coped quite well. I had to take it fairly slow to mimise chatter given the length of the boring bar. The fag papers are there because the 20 mm steel plate needed more taking off to get it flat than I had planned so these just shim the work up to get the centre height correct. I made full length tee nuts with three screws each so as to avoid over-stressing the Myford cross slide and tee slots - they are a bit delicate. I made a double eccentric centre for fine adjustment when working with a between centres boring bar, but couldn't use it for this job, not enough space. Photo available if anyone is interested. |

AFAIK - http://vts.bc.ca/metalshop/tstop/tstop.htm - stupid me, there's the size + thread of the bolt right there. Very simple device really - http://books.google.co.za/books?id=o9QDAAAAMBAJ&pg=PA125&lpg=PA125&dq=threading+stop+lathe+attachment&source=bl&ots=tG5JCzJ6ze&sig=M7mrVTBZ3iuBRWnt48zItRsXG-A&hl=en&ei=zl5jTcTZDY-GvAO45rDTBQ&sa=X&oi=book_result&ct=result&resnum=5&ved=0CDcQ6AEwBA#v=onepage&q=threading%20stop%20lathe%20attachment&f=false I'm scheming that I can use that hole + the travelling steady's holes to fab a poor man's cross slide DRO. Guys, thanks for posting your setups. I find it very educational. |
