Re: Felder F38 feeder repair
I just uploaded the F38 parts list to files/Manuals & Drawings/f38.pdf.
A pictorial of the "transmission" is on page 15.? By the way, there are two page 15's that are the same.

Re: Felder F38 feeder repair
Here's two pictures.? The F38 is about 10 years old,? Two of the drive gears cracked into several pieces when I turned the feeder on without a load
The drive gear is held in place with 2 snap rings.? The driven or wheel gear looks like it's held in place by the wheel shaft itself.? I will upload a diagram that Felder sent to the photos directory
I didn't get a chance today to remove the chain.

Re: Is there a list of build options with (rough) prices for KF 700?
I do not think this exists. Mine unit was specked several different ways with different prices, sometimes one option would be more or less expensive depending on what else was purchased.?
Kinda had me feeling like I was dealing with a used car dealer, but a nice one.

For example, I would like to know the cost of the motorize feature for the saw unit.
And for the shaper unit. And other options.

Re: Tannewitz Brake Questions

Power on the machine and a large electrical solenoid would energize and take pressure off the master cylinder.

When pressing the stop button the solenoid would lose power and the brakes would be applied.

Cut the pallet up and remove were you want the Oak skids to go Attach and roll out.
Just need a reciprocating saw and ?BFH and pry bar just beet what you don¡¯t want out trash it.
Than change the direction after you get it on flat floor in your shop.
For this stuff , IT is nice to have toe jacks , solid rollers , 5¡¯ pry bars , machine trollies and on and on?

it¡¯s too low and the machine would rotate.

I teach a class on making Shaker oval boxes every summer on a picnic table in the woods. It became the solution for fitting tops and bottoms very accurately, and quite quickly if you did a decent job cutting out with the coping saw. Mine is a converted Wards Master hand cranked grinder. I replaced the sharpening wheel with a plywood disc where the sandpaper is applied. I built a table fixture around it dedicated to the 3 degree bevel that we use on the parts. The grinder is geared so that you can crank a little and let it coast if you are just fine tuning. Everyone who's used it loves the thing. If only I could find a solution for dust collection!
I've been using the JDS Multirouter for nearly 25 years. One thing it can do that the Pantorouter can't is be a very fast production machine. When equipped with the pneumatic clamps, you can process chair parts at an alarming rate once you've got a setup. You couldn't do it any faster without spending exponentially more money on a twin table 5 axis CNC. I don't have any experience with a tenoner to know if that's a solution, but those are huge, single purpose machines not many of us have the space for. I mill brass and aluminum on the JDS.? Using a shop made jig which is essentially a vertical table, I can machine very small delicate parts like pickup rings for the guitars I build. I love that they use Thomson linear rails and bearings. The thing stays accurate year after year without any slop. I've never had a DRO on mine and I get by fine, but I'm sure I'd never go back if I installed it. It would be a slippery slope to have to add those all over the shop. Maybe as my eyes get worse...
I've thought of multiple improvements that could be made over the years, but they fall on deaf ears over at JDS. Now that they've been sold maybe things will change? I wouldn't be without one in the shop, or two or three. Down to just two now.
