Machined the new shaft for the worm drive of the tilting mechanism on the milling machine.
Fully machined on the lathe, including the hex for the wrench and the key way. It was a first for me to do a milling operation on the lathe.
For the key way on the shaft, I just held the part on one of the toolholders. For the hex part, I used a V block I made some time ago, attached it to another 90 degree fixture I had from completely unrelated machine. It worked perfectly.
You can also see the destruction on the original shaft. It does have a couple of faults on the design from factory. The smallest diameter, which will hold the worm and therefore have to deal with all the forces, only gets supported on one side (shaft side). I really don't understand why they didn't just drill the hole a bit further on the head of the milling machine, extended the shaft past the worm a bit, so it had support on both sides. The fault was that they used a woodruff key on the original shaft, this means that the slot is much deeper in the shaft, causing a weak spot.

Agree I enjoy seeing what a craftsman can do.

this morning the wife asked me to build her a new napkin holder. This is what I came up with. Now for final sanding and to oil it!

Cutting a radius on the corners and then a round over on the sides would make it nicer. Here’s a trick I use for cutting a perfect radius quickly. For one that small I’d just cut and sand it but for bigger ones I like to make a template to use a flush trim bit with.

Nice lamination. Hopefully you can disassemble the verticals from the base and run a round over bit with a router on the non mating edges of all the pieces.

No pictures, but I repaired my neighbor's tractor rims today... he has an old MF135 just like my dad's, and the back wheels had the hole for the valve stem ate out from years of calcium chloride loaded tires... he had the tires off, dropped of the rims to me a few days ago.
Cut out the valve stem area to a square about 1.25", took a 5/8" flat washer and knocked of the edges so it was the same size square, and welded in the hole. Smoothed down the welds, and once he paints them, you'd never know they were repaired.

Great day today... besides getting my propane heater finally working in my shop (its own thread) I also unloaded and placed my new 8in jointer in my shop. Time to read the manual then turn it on and make some chips.

Thanks... surplus sale... some scratches and nicks, pretty much new. A heck of a deal. Projects... yes, too many to count... a bookcase, a shoji screen room divider, a Murphy bed for our closet/extra bed space. Figured I better make sure I am outfitted before retirement. Pretty sure there won't be big tool purchases on a fixed income unless my tools are generating some.
My 6in jointer is now on the block. Hard to sell online these days due to the lock down. Running out of room!

I had a grizzly 6” before I bought my Powermatic 8”. I hung onto the grizzly for a while thinking there might be some use for it. I finally sold it and haven’t missed it.

Was thinking the same... 'hey I might use it... who am I kidding?'

She's a Beauty Dragoneggs did you get to run some test pieces through it yet? How is the set up from the factory ? Most new equipment needs some tlc. There is a good video by the wood wisperer on utube on that exact model check it out.:drink:

I've had my 8" Rockwell jointer since the early 80's and it's amazing how much more useful an 8" is over a 6". It seems most buy the 6" first, and then learn it's a mistake to do so, myself included.

My 6” was bought only out of affordability. I was 19 and going to school for fine woodworking. Our school shop had multiple 12” jointers so I knew the value of bigger ones.
On my list of future tool upgrades is either a new tablesaw or a new fence for my 1962 General, a band saw and a bigger jointer.
