Making a Fixture Plate and Boring Bar : Cement Mixer Restoration

Making a Fixture Plate and Boring Bar for the Cement Mixer Restoration. The Fixture Plate has a dual purpose. Size is 28″ x 20″ x 1″ A36 steel plate. I have made it to fit on my milling machine for large and difficult part mounting. The main purpose for the Fixture Plate is to be used a welding table. I have patterned the holes in the fixture plate following the 2″ x 2″ with 5/8″ holes. I have also made the 5/8″ dia. portion of the hole 5/8″ deep then the bottom fo the hole is drilled and tapped for 1/2″-13 thread. The threaded portion is for using the standard milling machine table strap clamp system which use 1/2″-13 studs.

  1. Hi Randy
    I built a welding fab table like this last spring, there are 3 videos showing the build. The third part shows how I built the legs, check it out if you like or don't.

  2. Nice plate for what ever you want to us it for. A very useful universal plate.

  3. The link for T-shirts and coffee mugs is on Randy's community page. Go there or be square! Everybody needs a RR in the Shop Coffee Mug. It wouldn't be couth to spill coffee on your RRITS tee shirt from any other mug. LOL

  4. A heck of a fixture plate. Approximately 157# before drilling all the holes. I don't see the link for the coffee cups. I checks some other videos. It's looking good. Waiting expectantly for the Boring video.

  5. Randy that was a big job setting up the fixture plate, a whole lot of Rinse and Repeat but the end result will be handy for several lifetimes, at least.

  6. Randy,

    Nice side project within your mixer project, this fixture plate looks great. If you desire to grind the surface of that plate I know where you can get it done!!

  7. Hi Randy – Thanks for this series. I've recently come across your channel and am impressed all round with your work and what/ how you teach us. 🙂
    For this fixture plate / welding table, could you leave the last two sides a little bigger so that you can install a fence there instead? – it'll give you more options for work holding!

  8. The plate that Dad used for a welding table is still around here, somewhere … short two of the legs he had put on it. It looks like it may have been a liner plate in a rock crusher at one time, with the ragged surface on one side. No idea what it is made of, or how tough it would be to drill or machine, I'm not sure I'd want to try. Breaking through that rough side may well be the bane of drill bits.

  9. Lot of work there, no wonder you have put it of till now. Should prove useful though.
    Tip for next time you want a square hole, drill four small holes in a square tangent to the desired square before drilling the bigger hole in the centre. An oldie perhaps but still valid, the tip I'm referring to not you or I. 🤣

  10. Anxious to see how your offset boring add on is going to perform… So far it sounds promising…
    If I get REALLY bored, I make holes in my 9 by 4 feet welding table, I'm not there yet… 😱😎👍
