Do you have a thread on this?

I have an ancient Rhodes shaper, I've always wanted a planer, but no space for it.

If I do I've forgotten about it.

Another way to cover the T slots is to use rubber sheeting & magnets much like one can do on a mill.

The local water well driller gave me a call the other day, seams they've been having trouble keeping the air filter clean on the 3406 Cat engine on the rig. The turbo housing was cracked and the exhaust was getting sucked into the intake. I suggested they take it to Calvin a local welder who did a spot on job, hope it holds. But with a new gasket it was still blowing out the joint.

Wonder why? None of that crud was gasket, it was carbonized cast iron, the surface was pretty much even with the flange to the side.



This was an easy one, clamped the face down and tilted the head then went over it with a fly cutter. Had to remove 0.065 to clean it up.



The face of the turbo needed cleaned up too, but what a beast to hold on to. Tried an angle plate and clamping to it but no luck. Finally ended up blocking the indexing head with the 3 jaw and grabbing the inside of the exhaust outlet, then using a jack and clamp at the other end. Need to spring for a set of adjustable parallels.





The exhaust manifold only took about an hour to set up and machine, spent 5 more on the turbo, was afraid to take more than 5 thou passes, the welds were pretty hard and not the most secure setup.

Take another look at the black and white pic a page or two back. That's a single belt system, 3 pulleys. The table dogs knock the shifting mechanism back and forth. There's a thing called a "shipper" (not visible) hooked around the belt and connected to that shifter.

Mine's a small planer. When the belt shifts, there's a little noise that you might call belt squeal. A bigger planer would probably squeal louder. I've a book on Cincinnati planers that show two belts, each riding on two different sized sets of pulleys to provide a faster return stroke. Youtubes on 2 belt planers show a delay, first one belt, then the other as the machine reverses direction. Installation should be straightforward, roll it over by hand and the belts should find their way.

60 fpm here. One speed!

Here's what I did today, got my phase converter finished
   
   

Plain old garden variety 240v single phase power goes in one side and, by strong magic, shiny new 415v 3-phase power comes out the other side. Runs my mill a treat.
The 5.5kw pilot motor is bolted straight to the frame, going to have to put some rubber mounts in there to hopefully get the noise to an acceptable level. So I guess that means it's only sort-of finished, but it was sure nice to get something working. Too many projects on the go at once around here.

Greg - nice fix. I never get tired of seeing your work. A set of adjustable parallels is on my list too.

Pete - looks just like a bought one. I am so glad I have 3 phase coming out of the wall

Had a little 4" cheap rotary table kicking about for a while that someone dropped in for conversion to stepper drive.
As a had a bit of loose time I started to do this.



Not the best table in the world but this is all the guy has. Motor is a type 17 as it only needs 5 gnat power to run this.

So bit of bodging, hammering, bashing and a tad of common sense and we get this.




Works OK and has a little backlash but nowhere near as much as I expected. See what the guy says tomorrow.

Nice John. I have a spin indexer I want to add a stepper motor to. But that's so far down the list of projects I'm not sure when it will surface.

[John S.]

Did a spin indexer ages ago.
Cheated though and bolted a commercial electric motor reduction box on it.

[EdK]

That's not cheating John. If I had one to use I'd use it. No sense in reinventing the wheel.
