Delay Wipers uncovered

[Roberts68]

I will get my switch pulled either tomorrow or at the latest this weekend for sure. You should have an email confirming payment shortly if not already.

I can remember when I had time and no parts and no money. Now that I have parts, and occasionally some money where did the time go?

Thanks again! I will take a look at the other items you mentioned via PM ASAP.

Gents - I've had some questions on the mounting of the actual wiper motor. Up front, here's my disclaimer: Based on numerous variables such as make/model/year as well as placement (smooth firewall / original location etc), the following is for reference.

The motor in the pictures below is mounted to plexiglass for demonstration. Thats nifty because you can see the 'layers', but also means at certain angles the picture might look odd as the motor floats in mid air.

On a flat/smooth firewall, or if you weld sheetmetal over your existing wiper motors hole, you will need to add 'standoffs' to ensure the motor (the actual motor, in the black canister on the new motor housing) clears the firewall. The standoffs / washers need to be at least 1/8". Mounted to the plexiglass, which is thicker than sheetmetal obviously, you still have 1/8" of space between the firewall and the inside face of the arm on the shaft. The measurement is actually .150 (but again, that's with thicker plexiglass, so you'll gain a bit more clearance on sheetmetal.)

You'll also see that I drilled two holes for the locating lugs (tits), but when I mount mine to the firewall I'm going to grind those off as the three bolts will locate the motor just fine.

As I've mentioned before, in theory and now I believe I've shown it, I see no need for a special "plate". As long as you can reach the backside (which you have to be able to do in order to attach the arm and linkage), you don't need a plate. Three 1/8" spacers and drill 4 holes and it should mount up just fine. Again, if you want to put it in the original location, I would suggest welding a flat piece of sheet metal over the original hole since it is larger, then drill the 4 required holes.

Thanks Robert - you'll get the first switch. If I could figure out how to serial number these things, yours would be #0001 (but I get to keep the prototype, so in 20 years mine will be worth more to collectors of "John's Wonderful Wiper" lol.

[Roberts68]

Great visual!

For a final install it should be possible to source either an 1/8" thick washer or possibly a machine bushing would work. As long as you could get correct ID & suitable OD.

In my case, unless I change my mind I will probably stay in the stock location with a fabbed plate. I would cover the original hole with the plate to make up the difference.

If I was to mount in stock location on a smoothed firewall I would consider some reinforcement to the firewall on the backside. When I worked on buses I saw what sort of wear and tear a wiper motor can eventually cause. Not that anyone with these types of cars will see as many wiper usage cycles as a decade old school bus in MN, but it is better to prevent damage by overbuilding than come back to repair damage if it occurs.

The one advantage of these "nipples", or are they "tits" now John? Is that they do not loosen. They will fight rotational torque even if a fastener loosens so esssentially there are 5 mounts... except the one is likely a locating pin for easier mounting during assembly on the line.

[JHunter]

Great point on the rotational force Robert. I suppose that's why the original motor was attached with rubber pads. I used washers for the test/demo, but your right again, I'll use something better suited for the task.
Sorry about the "tits", its what my dad always called anything that protruded from an item and it became a bit of a joke ~ 'you gotta grab that tit with a pair of needle nose pliers'.

[Roberts68]

No apology necessary. Raise your hand if you don't appreciate seeing a nice pair... anyone?
Yeah, as I thought.

I've posted the switch for sale in the classified section, using the new Enthusify application https://www.pro-touring.com/classifi...ntage-cars-617 . I don't suppose I can post a link to the website I made last night directly in this forum since I'm not a sponsor. But if you go to the classified section, look for the delay wiper switch you'll find a link with details on the switch as well as how to buy it. I've added wiring diagrams, the donor cars you can get the wiper motor from (there are more than what I listed), as well as an initial write up on how to mount the motor. Regardless of whether or not you want to buy my switch, I think there's some useful information on that page.

In addition, I did a new video that highlights the washer to wiper link. It still has that awkward silence while I wait the longest 20 seconds of my life when the wiper is in the mist setting lol.

[DarkoNova]

When I first saw the "tits" comment I lol'd. I have a different word for stuff that sticks up like that, and if anyone watches Metalocalypse, you can probably figure it out lol.

But man, if I didn't have so much to do just to get the Nova on the road I'd buy one of these right now. It's already been raining here lately so I NEED this, but working wipers don't do me much good if the car is just sitting in the driveway lol.

Definitely a must have item for me.

[JHunter]

I hear ya, my Camaro has been a project for 10 years - its pretty sad. I've driven it once, with no glass installed at 2 in the morning on a back road. Wear goggles if you attempt that, June bugs hurt when they smack you in the face at high speeds lol. Definitely not one of my smarter moves lol.

I've still got you on the list so when the timing is right just give me a shout.

A little update on parts for those that are following - all parts should be in by the 23rd. I went ahead and ordered enough components to make 10 switches. If this takes off I'll get a rhythm down as far as ordering parts ahead of time so there isn't as much lag time. I've just been hesitant ordering the parts and then having to find uses for them around the house if they don't sell - Christmas ornaments anyone? lol
For those that have paid for a switch, I would anticipate having them in the mail to you no later than the 29th and I'm going to shoot for the 26th.

Here is my wiper motor mounted up. It's just mocked up. I decided to do an aluminum plate to mount it to the firewall. I got a little creative to mount it to the wiper transmission. I had an old wiper motor, so I removed the main shaft, cut it down to the length I wanted, then drilled the main shaft and slipped it over the Cadillac wiper motor shaft. The only thing I don't know is if I should flip the motor the other way to give me more room for my engine and for the wiper plug to face towards where I plan on having wires enter/exit the engine compartment.

[Roberts68]

Gak68, I don't know for a fact that it won't also work that way but your motor is upside down compared to the ones I have seen. My friend had the DSE setup in his '69 'Bird with a Pontiac motor and it cleared well. The motor was clocked toward the master cylinder.

[JHunter]

Gak - that looks great, nicely done. I agree with Robert, most that I've seen have the can facing outboard, but it might clear. Did you make the plate yourself?

[gak68]

Yea. I just mocked it up with some paper, then cut it out with a bandsaw. I had some .250 aluminum laying around; kinda thick. I might flip the motor over tomorrow. I went online tonight and noticed that DSE are the other way too.

[gak68]

Tested out the motor today and they wipe perfectly and return to rest, the motor is nice and smooth; quiet too. I don't know if anyone else has one, but radio shack sells a regulated power source that puts out a steady 13.8 volts I use it all the time for electrical projects and problems.

*Edit, I ended up flipping the motor around, it is alot more out of the way and gives me easier access to my firewall mounting bolts.

[Roberts68]

Would you have a part number for the power regulator? I can hardly get myself to enter the local radio shack because the staff drive me crazy with their questions and they rarely ever have what I am after on hand anyway.
Seems I always leave there crabby wondering why I stopped in.
Glad to hear your system works great!
Thanks for the regulator idea, might be a good idea for a fuel pump... but what if the voltage supplied drops below the output? How does the regulator deal with that?

Sorry, I should have been more specific this is a unit that plugs into your wall outlet and converts your household current to 13.8 volts, so you can easily bench test electronics or test your auto wiring projects.

[Roberts68]

Oh wow! Classic example of two minds going in different directions.
That's alright though, Still sounds handy to have if you can still give more info. PN # And Price?

I guess radio shack discontinued it. P/N 22-504. But here is a similar device on Amazon: http://www.amazon.com/Racers-Edge-13...pd_sim_sbs_e_4

[carbuff]

Google or search Radio Shack's site for part number 7812. That is a 12v voltage regulator. However, I don't think it will source enough current for a fuel pump. I think they have a 1A limit...

I used a 7805 for something radio related in my C6...

[JHunter]

Robert - Got your old switch in the mail today so I can reskin it. Man, you're old switch is in way better shape than mine was - almost hate to cut it up lol. Thanks again for your order - yours is first out the door as soon as the parts come in. Still looking good for the last parts getting here on the 23rd.
