yah? weird shit? can happen.

The other day while? manhandling some large 2.5" thick walnut slabs on the bandsaw? I? lost my balance the room started spinning I had to let go the lumber and grab something to remain upright.

Turns? out there are little calcium crystals in the inner ear that can come loose and? out of nowhere you can't balance.? the room spins and? you are really? disoriented.

There are exercises? one can do to remove the loose crystals and? get them out from where they fell when they got dislodged ad? then you are golden again. takes all of a couple minutes. But man? it gives you absolutely? no warning.? One second everythign is fine and the next is ain't.

Yesterday in the shop, there were three of us fortunately. I'm usually aware of my surroundings and am quick to offer help before someone asks for it. Not yesterday though. I was applying finish, had my earphones on in my own world. That's when I heard the crash from across the shop. My shop mate had been on a ladder getting some wood off of the storage rack. We found him on the floor on his back, twisted up in a pile of wood and the ladder. He was unconscious and bleeding badly from the back of his head. Called 911. We got all the wood/ladder moved off of him and I rolled him to his side and applied pressure to his wound to stop the bleeding. I kept talking to him and he came to, and was totally incoherent for a couple minutes. He started to make some sense after a couple minutes, but had no idea what happened. The paramedics arrived within 10 minutes. They put a neck brace on him and got him sitting up for a minute, but he was very nauseous. They then put him on a gurney and took him out to the ambulance where they checked him out further. Ended up at HCMC, a level one trauma center. CT scan showed a brain bleed and skull fractures. His cognitive test results were good. Hoping for the best. He may be there a while. I shudder to think about if he would have been in the shop alone.?

Please check your risk factors. Ask for help when you need it. Your friends and family want you around.

I should think? that some enterprising? person? would long ago? have? started churning out 3-d printer versions of these things.

My Hammer? ZCI iused to be a real PITA? to make but I figured? out how to produce them? more efficiently with? fixturing? on the router table.? Now that I'm running a full size vertical knee mill I'll prolly take the job to the milling machine and speed it up even more.

There's a guy who sells the ZCI for hammer machines for? almost $70,? not a price I'd pay.??

So I decided I needed a zci for the new k940, thought I would get away without one but here I am... I reached out to David Best as I knew he had made one for the kappa. The k940 saw unit, top casting and 3 plastic segments appear to be the same however I have the LED lights so wasn’t sure if David would be willing to modify his design and if it would be worth the time/cost to do so. After a few back and forth emails David decided to not take it on, a few key dimensions were slightly different and could require a few iterations to get it right which I agreed.?

David was so kind in allowing me to use his drawings, however after I started to model it and compared it to my parts in hand it wasn’t adding up so I had to abandon the drawings given and just start from scratch from my actual parts.

So the first task was to model the LED section first as it is the most difficult to work out, then 3d print, check fit and make adjustments (done) After that 3d print all the parts to confirm (tomorrow) and finally have machined in aluminum (tbd)

The other unknown was how was the LED installed, the only way to find out was to remove it which would obviously void the warranty but after studying the elect schematic and looking at the parts drawings I convinced myself that it was no big deal and easy to fix if I screwed up the LED strip.?

So here are some progress pics... note, the 3d printed LED section is short due the the 3D printer bed not being long enough, a bolt hole is missing so it is not tight against the cast...

??

Below is the auto score feature in action with the as delivered LED section?

Love that dovetail detail for parts that dont fit on the 3d bed. I will have to remember that trick for future projects. ?What software are you using for your design? ?Sorry if you already mentioned it. ?

Looking fantastic,?

BTW, plastic is safer than metal to have around the blade. Are you having the parts milled (i think you mentioned AL) because some portions of the design are too thin to be robust in plastic?

?Welp looks like I am ready to have metal cut.?

- The scoring section was to long to fit on the 3d print bed so I made it in 2 pieces and connected it with a half lap dovetail.

- I modified the pockets for the dust shield to allow a little more adjustment, could have just made them go through the top except it would have left a corner that houses the LED unsupported and somewhat floating in space, probably ok but not as clean (of course would be hidden by the wood insert but...)

- I tapped the holes for the insert, I don’t like the m8 flat heads so close to the blade, probably ok but may just use some low head cap screws which are narrower and low because the insert is only 8mm thick but they are expensive and I can be cheap - out of the bazillion bolts we have at work in the assembly areas and the tool crib I can’t find any... could bling it up and use brass but then I would just be show boating ?

- The wood insert shown I just banged out tonight so not so refined, still need to cut the slot for the riving knife and will probably use it as is until the completed parts arrive - ?I also 3d printed a fixture to do the cutout with a 3/8” flush trim bit which should be done tomorrow?

My best to your partner. I had a lift of sheet goods come down on me but was hung up on a milk crate and didn't pancake my legs. After that I have my phone with me always. Thanks for the wake up call. We can never be too careful.

Jason,

I pray your mate comes out of it fully recovered and as soon as possible.

I learned this lesson when i was on the roof during constructing the addition behind my shop and my ladder fell. Yes, I know i need to secure it but it was on the opposite end of the prevailing wind side.

Another safety rule of our house, no chainsaw work when wife is not home. Does not matter if I have cell or not.

Thanks for the well?wishes. I will pass them along. He is stable this morning, with a killer headache. They will be keeping him a while to monitor the bleeding.

TJ, good reminder. It's good to listen to yourself. I always seem to know beforehand when I'm about to do something stupid. Sometimes I can't focus on things, I just leave and come back later. Or tomorrow.?

I see the value of the Apple watch now. I don't know if I can bring myself to buy one though. Hopefully Android watches copy that feature.

Paul,

I know exactly what you mean. I got sick of the gap between the planer and saw table and the poor, to me, operation of the rip fence.

I used a length of 40/80 slotted aluminium extrusion clamped to the front of the saw table and made up my own sliding fence. The arrangement is similar to how the Hammer fence is arranged. It may look a little crude but it glides accross the tables easily and is just as solid as the original Felder fence.

I incorporated adjusters into it so I can set it square and also parallel to the saw blade.

The only slight disadvantage is that it does not tilt.

I managed to do this without drilling or modifying the machine or original fence in any way. The extrusion can be removed by backing off two 13mm bolts 1/2 turn each.

If you're interested I'll post up a few pictures but I won't be back at work till Monday.
