I like the setup you used to round off the angle iron. I wouldn't have thought of that. -Sparky |

This is looking interesting. It could be my next distraction. Jim |

Looking good Russell :thumbup: Just a thought , change the grinding wheels ,those Clark wheels are really not the best ,they turn to dust quicker than remove metal :Doh: ,, still worth keeping hold of if you have a die grinder as you can use them to re-shape mounted grinding points . Keep the photos coming :thumbup: Rob |

I've been following this one, and enjoying your progress and photos. Might build one myself wen you're done. Keep it coming! :coffee: |

Thanks for your interest vtsteam, Rob, Jim, Sparky and Chuck. There's a bit more progress today. A bit of drilling and tapping to secure the upright to the mounting. Then I cut out the top surfaces and cut a couple of notches with angle grinder, chain drilling and file. I extended the holes in the bottom of the base to make adjustable mounting slots. These are deliberately a bit wide to allow some adjustment. Here's the progress now. The cutouts around the grinding wheel are deliberately a bit tight to allow for fitting after they're fixed to the pivots. So far it seems as though it will work OK. I can't see any in and out movement of the edge against the grinding wheel when I adjust the table with the edge about 0.5mm from the wheel. The aspect that I have been struggling with a bit is how much movement I need to build in to allow for wear in the grinding wheels without fouling the guards on the grinder and I was considering having the table wrap less around the side of the grinding wheel. Rob's comments on grinding wheels were helpful and I decided that it was better to replace them sooner rather than later so I made the notch in the table 25mm deep and I made the slot in the base long enough for 15mm of in/out adjustment - which is enough to take a six inch grinding wheel down to 4 3/4". I can always take a bit off the table or the guards if there is a problem. Here's a picture showing how the parts fit together. Bolts will be reduced in length. The only remaining tasks are to fix the table to the mounting and fasten the rest to the grinder baseboard. I'm thinking about how to do that - my plan was to use some countersunk Allen bolts from the bottom but I'll have to buy some before I can do that. I might just weld them instead. Sparky, I'm glad you liked my setup, it worked OK but would have been better if I'd bolted all the bits together a bit over size and then cut them down together before I put them in the lathe. That way I'd have had a flat surface for all the jaws to seat on. That's all for now. Russell |
