It's time to upgrade the 8520. I want to start back on the P&W 1830 Radial and need more height. I am going to fabricate and install a 4" Riser Block to extend the spindle to table distance from 15 3/8" to 19 3/8". Here is the preliminary print.
Material -- Center tube DOM 1020 6.5 OD X 5.250 ID X 3.0 long. Upper and lower flanges 1018 7.250 OD X 1.0 long

As always, wood comes before metal. Mistakes cost less.
I will clean it up tomorrow and see how it fits. Better to find out now if it needs to be longer or shorter.

That is one big napkin ring you have there Bill
Looking forward to seeing your progress on this.

So, I'm a sloppy eater. LOL Gonna fit that ring today. I just need to add the locating pins. I have material either ordered (Pip - DOM 1020) anr the flanges 7.500 dia 1018. to make 4 of these. Two are already spoken for.

Bill,
That looks like a worthwhile project. I have a riser block in the Jet JVM 836 milling machine and feel its almost a necessity. It was a Grizzly piece (#H8107) , that was sold for their #G6760 milling machine, which is very similar to the Jet and had to be slightly modified to work. I made a couple of the riser blocks for the 6" x 26" milling machines (Grizzly, Enco, Busy Bee, etc) for some friends.
This is why I use wood instead of steel for a model. It has more distance but still falls 1" short of what I am after. Saved a few bucks here.

Good idea prototyping in wood. It certainly was well worthwhile this time for sure.

It's harder to explain a mistake to the War Department than it is to a Supervisor. Wait, is there really a difference?

Interesting prototype, good use of a wooden one first to check things out.
