Finally got the mill bed back and fitted. Started machining the two pieces of the base square and to size. For the long facing cuts I experimented with a stepper motor as power feed. For now am using a pulse generator of eBay but, it is not performing as I would like at slow speeds so will be building a different one. Am quite happy with the finish. A short video of it in action. The one piece was quite a bit wider than needed and I do not have any means to slice it down so an end mill was used to cut it down, also under power feed and it cuts like butter. Cheers Abraham |

Hi crazymodder, I use clear contact adhesive, gives a good bond and "peels" of after. Abraham |

Hi all. Finally got the power feed working. The material for the base and sub-base was machined square and to size. The sub-base was drilled and the slots for the anchors cut, drilled and taped. The holes from the bottom of the base was drilled, taped and counter sunk. Flipped over and the top was drilled and taped. The slot for the crank was partially cut with an end mill, have a side and face cutter on order to finish the slot. The top face was given a light skim to finish it off. And the two bases together. Two strips of plate was squared and machined to size for the anchors. Made a simple bracket to setup the rotab. The rotab was used to round over the ends of the anchors. Things got a bit involved and I forgot to take any pics. After mounting the anchors to the sub-base the assembly was given a face cut. The base assembly so far. Cheers Abraham |
