| Draw Bar T-Wrench? |

| Rikk:
Hope someone can help here, I bought a BF20L (G0704) a few months ago, it came with a draw bar t-wrench with a square hole in the end about 8.3mm square. Been using this quite happily but yesterday the tool broke and I'm finding it impossible to find a replacement or even a square bit to go on a ratchet. Any pointers as to where I can get one from, in the UK prefurably. I have emailed the maker but still waiting a responce. Thanks ...........Rikk |

Hi Rikk, I've got a little plumber's tool like this http://www.screwfix.com/prods/16428/Hand-Tools/Plumbing-Tools/Specialist-Plumbing/Services-Cabinet-Key . Each arm has a different socket on the end. One is a mystery, the second is triangular for opening outdoor gas meter covers, and the third and fourth are square. The larger square one is just over 8.3mm across its internal flats. It measures about 60mm from wingtip to wingtip. Made of rubbish metal, thpugh. A better plan would be to base something on a bit of round bar. Cut it lengthwise, mill a slot 8.3mm wide and 4.15mm deep into each of the cut faces, then braze the bar back together. That will give you a not quite round bit of bar (because of the kerf) with an 8.3mm square hole through it. I'm sure you could work that idea up into a T wrench. Andy |

Thanks for the pointers guys, never thought about splitting a rod length ways, neat idea :) Hmm actually I might use a bit of rectangular section to make up a square tool, save a little cutting ;) I'll have to get one of those cheapy ones for now as I don'y have anything to tighten up the draw bar to make it. Can't believe these things are so hard to get. I had intended using a cheapy electric impact wrench for doing it up and undoing it but as I can't find anything to fit the end that went out of the window. Out of interest (I've not been doing this long) how tight does the drawbar need to be done up, is it TIGHT, or just just enough to hold the taper in? |

Rikk, I purchased a BF 20L clone, Grizzly's G0704, and it was only supplied with an 8 X 10mm open ended spanner for the drawbar. There is a picture in the manual showing it being used. |

My collet chuck didn't come with a drawbar, and I did just that. |
