Why not use one rebate cutter and multiple passes? That would save you a dedicated device and you could do it on almost any shaper or dado capable (slider) saw. 1. Cut the material to width of your ties and as long as you possible can 2. Setup for the first rebate by setting the correct height for the shaper from the outer edge of your workpiece/set fence of saw and feed all your stock 3. Flip stock by 180 degrees and feed again to make the second rebate referencing the other side and feed all your stock 4. If the rebate is not wide enough repeat step 2 and 3 (to readjust your shaper or fence when using dado on saw) until you have reached the desired width 5. Now cut the material orthagonal to the orientation of the rebates to make the individual ties If you use a cutter with a width close to 1" but smaller than 2" you only need two passes for each rebate. WIth a shaper and a feeder this should be done pretty efficiently. Kind regards, Jonathan

Glen,
Got it. ?You’r’e on the schedule as soon as this pandemic is under control, the roads open over the pass south, the California wildfires stay in remission, and Quince restaurant reopens in SFO. ?Until then, check out my new pole dancing class videos on Parler.

Re: HP needed for heavy cutter?
You're not removing much material here, you don't need a ton of horsepower.? ?It's the equivalent of a 1/2" diameter router bit cutting 3/8" deep.
These ties are presumably about 3"x3"x16".? I think most of the work is moving the material around.? Loading a dozen or two on a sled, pushing the sled, etc.? If you did it on 4'x8' CNC router, you'd spend 10 minutes loading the table with 96 ties, 30 seconds cutting them, and 10 minutes unloading.
I think I would approach this as a router table project.? Mount two routers with bits like this:
I don't think you need a sled.? ?A low-friction infeed table with a fence, and a push tool that is square to the fence, is all you need.? ?Just put about a dozen ties on the infeed table up against the fence, and push them through.? Someone picks and stacks from the outfeed side while you load the next dozen.?
Depending on the density of the ties, gravity may be adequate downward pressure, but if not, you just need something to apply modest pressure.? You could do something with wheels, but you could also use a couple $2 plastic featherboards, or just lay a board of the appropriate weight on top the stack you're cutting.?
Assuming it takes about one minute to load up and push through a batch of a dozen, it's 25 hours of work for 18,000.

Re: HP needed for heavy cutter?
So how wide is this assembly going to be. 4 or 5 sets mean 4 to 5 feet mib width, if grooves are on the edges of the board.
Can you really do that w/o and support in the middle?
If you can live with less width a moulder like woodmaster (assuming material is not too tall) should work with self feeding. You can buy them used and resell them after you are done.
Bit safer with cutters enclosed. Dust collection is not great but that can be immensely improved for a dedicated setup.
Just a thought.
Imran?

Re: HP needed for heavy cutter?
Mount urethane feeder wheels on spindles above the cutters to maintain down pressure as you cut. Rig up a sled with pneumatic cylinders to push the slats thru.?
You might want to find someone with a CNC router with a vacuum table, load the whole table and slot the slats with a 2” cutter to depth. You don’t say actual size of the slats, but you might be able to load 75 to 100 parts at a time on the full table.

Re: HP needed for heavy cutter?
Can you use 50mm (1.968”) wide instead of 2”? If so, you could get two of the Hammer rebate cutters #500-04-003 and stick them on a 30mm shaft with spacers between. As for hp, they are aluminum, says they weigh 4.6lbs, I would suspect 3hp should handle it without much trouble, especially with the insert cutters that are staggered like these.

Jason with all this 3d printing talk I didn’t even thank about that. I am in the same camp as a former multi-router owner it is the only one I am considering, would love to get my hands on the pantorouter to be proved wrong. As far as 3d printed templates I don’t see why the tapered tenon 3d printed couldn’t be used on the multirouter router as well using their holder or making something?

Just to follow up, I'm not able to get the photos off that old computer (now I remember why I replaced it).
If you are serious about going the Ivac route and really need to have photos, let me know. John Kee was very generous helping me get this set up on my RL160, and I'd be happy to go the extra mile here. It's just a bit of a pain to get into that top panel...

I looked at the Woodpeckers Multirouter, a couple of weeks ago, but decided on the metal Pantorouter ($1800) and absolutely loving it.
It’s super easy to setup and repeatability an accuracy is great.
