Bumped into a guy from the old days on a fan purchase, Bruce Dirks, hadn't seen him in 10 years or so. We got to talking, his favorite fans are battery fans and I had just found the Porter No. 4. He came by this weekend and brought some prototype blades he's working on specifically for the small -- and medium size -- battery motors. They're 6 wing blades right now, he brought 2, an 8" for the No. 4 and a 6" for his Knapp BB which we also tried out on the Porter No 2 I have in my collection. Please forgive the poor pictures and the messy desk. I'm still working on getting the purple paint off the No 4, but it's coming along, there's about 90-95% of the original finish left underneath, but am not sure I can save the ornamentation, the prurple paint really adhered to it.


 


Regardless, thought I would share his craftsmanship, I ordered a 6" for the No 2 and he's making a 9" for the Porter 4 as well, but with thicker wings. The 8 looks a tad small on that big motor. He'll be making more if there's interest, look for him as a "new" member in the new member section of the magazine, they look really nice, the hub is really nice. I'll chemically age mine when I finish the two "fans."

It's really nice work for a guy in his garage George, the hubs were done at a machinists, the wings were cut and assembly done by Bruce. We measured out the shaft size on the No 4 to .226-7 and the machinist matched it out perfect. The wings are in clock as well.


 


Forgot to mention the No 4 runs super nice as well. I'm never going to find an original blade -- I don't think -- so these will make nice displays even though they're not original. I'll add a base, binding posts and switch assemplies to both and pop them on a shelf.

Hey Michael, those look awesome ! My favorite fans are battery fans and I have a bunch that need blades. I would love to get in touch with Bruce.I looked through the past few issues and could not find Bruce's contact info and I also sent him a PM through the forum over a week ago but have not heard back. Could you PM me his contact info ? Thanks C

I'm sure Bruce won't mind, you can call or text him at-- Two 2 four 634 five 7 nine 4 --. He has several new hubs, so get in touch with him. We worked a little on the blade shape last week, trying to get it just a smidge wider, so he has a couple of pics with the new shape, see what you like, old or new. He will also be doing 3 wing blades later on. I've seen the hub pattern, it's really nice. Super easy guy to work with. 


 


If you get something done with him, make sure to take some pics. I have one side of the Porter 4 completely stripped and am 50% done with the other. I'll have mine put together by mid May.

Here's a quick update. I picked up a blade set for the Porter 2 a few weeks back and slapped it together on a scrap piece of oak complete with terminal connections and a switch. At 4V and about 1 AMP, the little bugger runs smooth as silk. While I like the six wing blade on it as a display piece, I have a 3 wing on order for it which looks like a pic of one I seen. 


 


The Porter 4 is moving along as well, but a little slower than I anticipated but I have it mocked up on a base, I just need to blow it apart and finish all the pieces.
