TJ,
that is good info. i have never explored braking on the VFD that runs my RL125 but i believe it works the same way and supports ext. braking resistor. just curious, how does your VFD communicate if internal braking is not sufficient? just by braking time, i.e., it self protects?
imran?

The parts are from Automation Direct. My constraint was that I didn't want to exceed the existing footprint of the saw with a big VFD enclosure, and the logical place to mount it was under the motor. That limited me to about a 10" wide x 6" deep box. I ended
up using a 10x10x6, but if I could do it again, I would get a 10x14x6 or so - that extra couple inches would have made cramming all the stuff inside a lot easier.
I used a Weg 3HP VFD (my saw is 2HP, so I upsized in case I ever replace the motor) which is pretty compact. My shop is in my house and I have trouble with VFDs tripping my arc-fault breakers, so I put in an input EMI filter to keep the saw from causing problems
in my house. The enclosure also has a 25A disconnect switch, a pilot light, and a 12v power supply. I wanted to do remote speed control and programming, so I opted for the remote display, which is what required the 12v supply.
The controls are 22m buttons from Automation Direct. These are pretty cookie-cutter parts. The VFD is setup to run in a 3-wire mode with a normally open start switch going to one digital input and a normally closed stop switch going to another one. The knob
on my control panel controls the speed from about 3Hz to 66Hz, which gives me a range of very slow for setting blade tracking up to about 5000fpm if I overspeed my 900RPM motor slightly (slightly meaning 10% to about 1000RPM).
The enclosure was heavily modified to get all the stuff in plus cooling. I have a Bridgeport that I did most of the drilling and cutting on, however I confess I cut a couple corners in the interest of time and due to the awkwardness of clamping something as
wobbly and large as this box, so the rear louver cutout and the drilled cooling hole pattern on the bottom aren't exactly machinery-tolerance.
The airflow of the VFD is bottom to top. I don't like top-mounted vents, so I drilled a bunch of intake holes at the bottom of the enclosure and the air exits the louvered vent out the back.
Most of the disconnect switches like this use remote handles and are shaft driven. I mounted the disconnect itself where it had to go in the box and then carefully measured where to drill the door for the handle.
To mount the user controls I got a piece of steel plate and drilled through the back of the saw housing. The blade guard slides up and down on the side, so I couldn't mount it there. The user control box is a 6x6x4 Hubbell-Weigmann enclosure. I made a custom
faceplate for the buttons and VFD screen and had to hog out two sides of the 6x6 box to get stuff to fit, but I'm happy with how that turned out.
For some reason my saw had a strange slot milled perpendicular to the blade. Northfield has no idea what that was for and is sure they didn't do it. I machined an aluminum slug to fill that in.
If anyone is interested, I'd be happy to provide a BOM of what I used.

Re: General Woodworking Question
Morning Rob, I’ve been a great advocate of multiple passes with both the router and spindle moulder for years, usually using different bits or blades! And or tilting the spindle! That’s why I first bought the Felder, mine is fairly old now, a BF-631 circa 1996 but we’ve grown together and I’m very comfortable with it and wouldn’t dream of a so called upgrade! I did dally once with the idea in the early 2000’s but then read a lot people’s reports about how good mine was as opposed to the new versions mainly that it was designed as one machine and not two bolted together! Thus stays accurate! I’ve found that playing with the options of what a cutter or router bit (or section of) can give you can produce remarkable results! I’m a renovator of listed property and years ago when having to replicate an existing moulding would order specially made cutters. That was fine until they started to cost the world now I can usually manage to replicate most profiles using what I have either in my tooling or with standard options! I start by visualising how they would have been made using old hand profile planes, what combination of these would have been used to achieve it and then I look for the parts of cutter that will give me that option. The spindle moulder is in fact far more versatile as you can turn blades upside down and reverse the direction of feed to access a completely different profile from the same set of cutters! Best of luck with the project Rob, if you’re still stuck post me a profile with dimensions and I’ll see if I can find a solution for you using standard euro cutters!

? Martin,
i am fascinated with the fact that this is possible with just a stopped cut on the shaper. to be sure we are speaking of the two beads/fillets that terminate in the V-shape - circled below. i assume the space between the beads is close to a round over.
i can see tilting the cutter to get the V but it would need to tilt parallel to the direction of feed, correct? i am only aware of spindles that tilt perpendicular to the feed direction.?
i am terrible in this kind of thinking but i like this detail and a challenge, so would love to learn if it is possible to do it on shaper.
round over bit was mentioned with raising the cutter, i assume to get the V detail. i am unable to visualize that.
the two beads appear to have a round top, if so that is sweet. a typical bullnose type bit will only do a fillet.
good stuff.

? Hi Rob, This moulding was produced on a spindle moulder with an appropriate cutter set and probably tilted as well! This enabled the shallow v grove to be cut and produce the corner bead. Executed as a stop cut you can see that the diameter of the profile of the cutter is far greater on the top side of the corner bead than on the v grove. To give you a clue the cutter profile will be of the architrave type! Hope that helps!

? Michael,
i assume robert is talking about the vertical routing detail that terminates in a V shape in top.
i would attempt to make the two fillets with round in between with a bullnose type bit in one pass.
round over bit would require two passes but complicating the stoping point as it would be beginning of one pass and end of the other.
i figures just use a chisel to make the V shape and then cleanup. not sure if there is enough material to use a hand router plane as it would be ideal.

The “v” or grove on the right? There’s always the possibility for chisel clean up for square corners. Unless I’m misunderstanding. I don’t see the detail very clearly on my phone to analyze the nuance.
It’s a three part cut from what I suggested. 1) round over full length. Then probably the same bit, but 2) raise it to get the step on a stopped cut. This is the front. 3) For the groove on the right side, it looks like a stopped
groove or v.
I cannot see a way to do it all at once if that is what you think I was suggesting.

Michael,
if i understand what you are saying correctly, let’s say the roundover bit is making the lower fillet and bottom half of round. how would you drop the workpiece while still traveling to get 1/2 of the V shape? seems like the travel to drop distance
ratio is close to 1:1.

Looks like a stopped cut to me if I’m looking at the right thing. I’d probably recreate that with a round over then drop it to make a stepped round over in a stop cut setup. The groove or v would follow the same stopped cut plan.

I have ordered a heavier spring from Iturra and a couple fences from Northfield - the conventional fence, and the resaw fence. I'm still fine tuning, but I think it's going to work out pretty well. ?Thanks again for the help.

Re: General Woodworking Question
Martin,
i am fascinated with the fact that this is possible with just a stopped cut on the shaper. to be sure we are speaking of the two beads/fillets that terminate in the V-shape - circled below. i assume the space between the beads is close to a round over.
i can see tilting the cutter to get the V but it would need to tilt parallel to the direction of feed, correct? i am only aware of spindles that tilt perpendicular to the feed direction.?
i am terrible in this kind of thinking but i like this detail and a challenge, so would love to learn if it is possible to do it on shaper.
round over bit was mentioned with raising the cutter, i assume to get the V detail. i am unable to visualize that.
the two beads appear to have a round top, if so that is sweet. a typical bullnose type bit will only do a fillet.
good stuff.

Hi Rob, This moulding was produced on a spindle moulder with an appropriate cutter set and probably tilted as well! This enabled the shallow v grove to be cut and produce the corner bead. Executed as a stop cut you can see that the diameter of the profile of the cutter is far greater on the top side of the corner bead than on the v grove. To give you a clue the cutter profile will be of the architrave type! Hope that helps!

? Michael,
i assume robert is talking about the vertical routing detail that terminates in a V shape in top.
i would attempt to make the two fillets with round in between with a bullnose type bit in one pass.
round over bit would require two passes but complicating the stoping point as it would be beginning of one pass and end of the other.
i figures just use a chisel to make the V shape and then cleanup. not sure if there is enough material to use a hand router plane as it would be ideal.

The “v” or grove on the right? There’s always the possibility for chisel clean up for square corners. Unless I’m misunderstanding. I don’t see the detail very clearly on my phone to analyze the nuance.
It’s a three part cut from what I suggested. 1) round over full length. Then probably the same bit, but 2) raise it to get the step on a stopped cut. This is the front. 3) For the groove on the right side, it looks like a stopped
groove or v.
I cannot see a way to do it all at once if that is what you think I was suggesting.

Michael,
if i understand what you are saying correctly, let’s say the roundover bit is making the lower fillet and bottom half of round. how would you drop the workpiece while still traveling to get 1/2 of the V shape? seems like the travel to drop distance
ratio is close to 1:1.

Looks like a stopped cut to me if I’m looking at the right thing. I’d probably recreate that with a round over then drop it to make a stepped round over in a stop cut setup. The groove or v would follow the same stopped cut plan.
Just some ideas

Folks,? this is less a question about my Felder machines and more a question on edge detail and ending a round over detail prior to the end of the board.? The attached picture is as they say ... worth a thousand words and its what I'd like to do but have
no idea how to achieve the look.? I've tried a few different methods on exiting the router but can't get this look.? Any ideas would be appreciated.?

Re: Powermatic 141 bandsaw
Thanks Joe, guessing this one is mid 70’s probably fair price assuming it’s all in order

Well here I go again, any opinions on this 141? I had planned on using my little inca 260 for small stuff which I have been until I discovered some issues with the lower wheel, it needs replaced and the cost is close to $300 - i am super
attached to that little saw but possibly not $300 dollars attached
Could possibly be a replacement but the price seems a little high, i would only really only use it with a 3/8” blade or under. I do have the laguna 14/12 which I planned on using for 3/8” and under once I bought
a larger saw for resawing but that larger saw is on hold for now, the laguna actually resaws pretty well at 8” and under and just so-so above that

Re: Tannewitz Brake Questions
What ever is the simplistic and cheapest I would avoid using a brake Justin case of emergency. In larger machines bigger hp I would use disc brakes . My oliver has an over ride that cuts the motor if the blade brakes than using the manual rub brake. My best advise is don’t stand to the right of the blade so your not buy when blade breaks.

?My saw serial number says it was built in 1967 and it was built with hydraulic brakes.? At some point it was converted to the electronic brake setup Tannewitz uses now. I have not torn anything down yet, still don't have it off the pallet.? But it looks like the solenoid that drives the master cylinder for the brakes may be fried.??
I had intended to restore it including the brakes but this will be a saw I intend to use and I assume the electronic brake is a better system than the car brake setup. Does anyone have experience?
