I heard talk of rotating around, though some of the classes that have a small number of people may move around differently in order to balance out the numbers.

I enjoyed the show.  Looking forward to more.
53  General / Technical Help / Re: Car scales and corner weight? on: April 02, 2016, 04:04:27 AM
I could bring the scales to the Practice Autocross in May.  It would give you total weight and rough balance.  Highly dependent on how flat and level an area there is to set them up.

We're trying to find a nice shade of maroon.  Maybe something like this, with no stripes.

Also, I raced yesterday, but not as a member, if i choose to become a member, can I get my points for that race added to the championship series?

If you join this year, your points from this race will count.  Joining is easy and gets you your permanent number, plus the $5 discount each event.  Here's the link Smiley

Thanks, Engelbert.  The 3D printing is pretty interesting.  I've wanted one for a few years and this seemed like a good excuse to buy one.  If you need anything done, let me know.  It's really good for small parts and brackets.
57  General / Autos and Autosport / Re: Factory Five Cobra Build on: March 19, 2016, 04:07:52 PM
Well, I finally buttoned up the brake hydraulics.  I got to use the 3d printer to print out a grommet where the soft brake lines, hard brake lines, and wiring harness come through the firewall.  I printed it in two pieces to sandwich the firewall.  I also left opposite-facing slots in it where the wiring harness comes through so that I could slip it over the harness, instead of trying to pull the harness through.

Here is the hole in the firewall that I've gotta put the 4 brake lines and wiring harness through




And the grommet




I installed it around the wiring harness and then pulled the soft brake lines from the reservoirs to the master cylinders




Once that was in, I pushed the hardline through, bent up and flared the portion inside the car that connects to the master cylinders






I filled the master cylinders and pressure bled the system.  I found some leaks, but thankfully after tightening the fittings down some more, everything seems to be fine.  The stainless steel lines need a lot of torque.  I think I'm gonna try and button up the cooling system next.
58  General / Autos and Autosport / 1st Gen Ram Rebuild on: March 13, 2016, 03:56:00 PM
So, most of you know I use my Caprice as my tow vehicle.  I love that car, but given the likelihood of open-top track day cars in my future, I'd like to get an enclosed trailer and there is no way I can pull that with the Caprice.  The T56 is already well beyond its design limits moving 10k lbs of car and trailer.  And even the club's small enclosed trailer acts like a giant air brake behind the Caprice at highway speeds.

I've always loved 1st gen Cummins trucks.  I've regularly scoured Craigslist and eBay for them.  I made a deal to buy one about 5 years ago, but it was a Sunday and the bank wasn't open, and someone offered the seller more money later in the day.  Anyways, about 18 months ago, I found a fully loaded extended cab, 4x4, 5 speed truck on eBay.  I made a deal with the seller, drove the Insight up to Long Island, and drove the truck home with the Insight behind it on a trailer.  The good news - the truck was mechanically overhauled a couple years before I bought it.  The bad news - it spent its whole life in NY, so it's a little bit rusty.

Here are some pics from the seller's original ad










Here are some shots of the floorboards.  You can put your hand through them!






I've driven the truck a little.  Hauled Paul's car to VIR last year.  There's a lot more room for sleeping in the bed compared to the wagon Smiley






I also started looking for a clean cab once I got the truck home.  Last summer, I found the perfect donor - a rust-free extended cab shell.  It was a gas truck without a motor.  I went and picked it up with the wagon.  I wish I had taken pictures because it was super sketchy.  The truck is longer than my trailer.  The interior is pretty nasty after having sat outside with the windows down for potentially the last 8 years, but the sheet metal is clean!








Jeff's been giving me a hand with a bunch of stuff in the garage recently, including starting to pull the truck apart.  He got the whole front end off this weekend.  4 bolts and we should be able to pull off the cab.  Then I can get the heap out of the garage!




I don't expect to start making much progress until I'm done with the Cobra later this year, but I'm looking forward to it.
59  General / Autos and Autosport / Re: Factory Five Cobra Build on: March 13, 2016, 03:28:56 PM
Got a couple small items done this weekend.  I don't have pictures of everything.  I re-made the fuel line that connects the two fuel rails.  The engine builder cut it too short and also only installed it half way onto the fittings.  He also only installed 3 of the 4 fuel rail mounts, so I ordered and installed another.  Not a big deal, but disappointing.

I made a couple of tweaks to the 3d printed master cylinder reservoir bracket and re-printed it in black




I also re-bent the power steering return line and mounted the lower radiator tube Paul welded up.  I raised the cooler up to make more clearance for the radiator hose.  If you compare the shot of the lower radiator hose to the one a couple posts up, it is much better.






Jeff also helped me frame a 42"x56" poster of the LeMons car that I had made like a year ago.  I made the frame out of a 2x4 and box jointed the ends.  Now I need to figure out where to hang it.

Since we got rid of Danielle's R56 base Mini Cooper last year, I've got the remainder of a case of Amsoil 5w40 Euro Car Full SAPS motor oil.  7 full quarts.  Figured I'd see if anyone could use it.  $40 for all 7 quarts.  I can bring them to the first autocross.

61  General / Open Forum / Re: My Garage Build - The Airboxer Garage on: March 10, 2016, 05:48:05 PM
Can't wait to see how the paint turns out!
62  General / Autos and Autosport / Re: Street-touring Pony build on: March 05, 2016, 07:38:56 AM
That looks pretty sweet. So much tire!
63  General / Autos and Autosport / Re: Factory Five Cobra Build on: February 14, 2016, 07:00:13 PM
Alright, I'm back at it after getting the Miata mostly squared away.  There are a few things left that I need to take care of before I can run and drive the car:

Brakes
- install master cylinder reservoir
- bleed brake system

Cooling System
- install overflow tank
- install lower radiator tube, ensure fit
- install heater hoses and heater valve
- fill, bleed system

Fuel System
- remake fuel rail crossover hose (engine builder did poorly)
- add missing brace to fuel rail (engine builder only installed 3 of 4)

Misc
- re-make PS return line
- oil, transmission fluids
- clutch line
- throttle cable
- install headers, exhaust

Wiring
- all of it Sad

I started knocking out some of the easier stuff this weekend.  Of course the brake and coolant reservoirs Factory Five supplies are garbage.  The brake fluid reservoir may hold 4oz of fluid...and it's not vented.  People report issues sucking the reservoirs dry or creating a vacuum because they are not vented.  Great.  So, I ordered some nice reservoirs, but now I need to find a place to mount them.  It looks like the driver's side frame tube at the top of the engine bay will be the best spot, but the hard brake lines I made are in the way.  Jeff helped me start to remake them so that they snug up under the tube.

At the same time, I need to make some brackets to mount the lines and the reservoirs.  I got a 3D printer last month, so I decided to mess around and print some test brackets for the brake lines and the brake reservoir.  The brake line clamp is simple, it spaces the lines about an inch out from an existing mount and has two holes for the lines.  I printed these out of cheap HIPS plastic, which I bought in red.  I'll remake them out of black ABS or maybe some polycarbonate, if needed.








I printed the block 80% hollow, with a 1mm shell.  I wanted to see how strong it was, so I decided to try and jack up the Miata with it.



That's the back wheel off the ground.



The block survived fine, you can see where it made an impression in the wood.



Here, I cut the block open.  You can see how it's supported internally.  Seems to be plenty strong.




Jeff helped me mock up the brake reservoir bracket.  I need to make some adjustments to the size, but that's easy to do since it only takes like 5 minutes in SketchUp, then I can re-print overnight.










I'll start knocking stuff off the list and hopefully have this thing running in a couple months.

Looks great, glad to see it back on the road!

Heard you may have some luck using a heat gun to pop those front dents out.

Good call.  I may try that out.  Now I'm worried about the car being too nice, considering this was my winter beater Smiley
65  General / Open Forum / Re: Dyno Day on: February 01, 2016, 11:59:17 AM
Just trying to get some baseline pulls.

Guess your baseline numbers!

I may actually bring the Miata, since it runs now. I'll guess 101hp, 108ft-lbs.
66  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 31, 2016, 06:48:12 PM
The dents in the front bumper are where the previous owner screwed the license plate through it.  Unfortunately, that's the nicest one I had.
67  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 31, 2016, 05:22:48 PM
Well, almost exactly 4 months after hitting the deer, I took the car out for it's maiden voyage after rebuilding it.  I'm happy to report that it seems to run fine.  Jeff gave me a hand putting the top and all the trim back on and then cleaning everything up.  I still need to paint the headlight covers, clean the wheels and tires, and charge the AC system, but it's together!

I'm pretty happy considering 4 months ago it looked like this:








And then it looked like this:








Now it looks like this!







68  General / Open Forum / Re: Dyno Day on: January 30, 2016, 09:14:36 PM
Ah, bummer.

1994 Chevy Caprice
6 speed
stock except for exhaust

I'm hoping to see over 230whp, 310ft-lbs
69  General / Open Forum / Re: Dyno Day on: January 30, 2016, 06:03:04 AM
I'm in and I'm going to see if I can start a trend - guess how much hp and torque your vehicle will make.  I'd like to baseline the truck.

Justin Loehlein
1993 Dodge W350
Cummins, 5 speed
Dually - if the width is a problem, let me know

My guess, without having any clue what these things dyno at is 135hp and 300ft-lbs.

If the truck doesn't fit, I'll run the wagon.

That's a lot of sheet metal work!  Looks good.
71  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 19, 2016, 07:09:22 PM
Justin,
     How many coats of clear did you have on it and how did you go about wet sanding with the 1200, I am worried about going too deep on the Civy.  I too have lots of orange peel.  Also curious .... how do you get the pics to post in the post?
Thx
Mike D

I laid 3 medium-thick coats of clear (Value Pro HS Clear) and had a bit left, which I sprayed on the hood and trunk as a light coat, which really messed them up.  To wet sand, I did small sections (edges first, then < 1' square sections).  I used a small DuraBlock scruff pad, wrapped it in sandpaper that had been soaking in water for over an hour, then sprayed the section I was sanding and sanded a little bit, dipping the block and paper back in the water frequently (every 5-10 seconds?).  After a little sanding (5-30 seconds), I would wipe down the section with a towel and look at it against the light.  You can see the low spots because they're still glossy.  I repeated until everything was evenly flat.  After that was done, I had to compound with the denim pad 3-4 times and polish with the foam pad another couple times.  I'm sure others have quicker ways, but it was my first time trying to make anything look nice so I'm learning as I go.  Also - it's easy to take off more, but a paint in the ass to add it back, so I erred on the side of going slowly.

I use the BBCode image tag to post my images, which I host on Flickr.  Flickr also has a share button that has a BBCode option that will give you the code to paste in with some extra junk in it (like a link to Flickr).

This looks very good.

I usually load the spray gun with reducer and spray a mist of it all over what I have painted. That cleans out the gun, and it makes a smooth surface, and leaves no orange peal and no need for sanding and polishing.

But that's just an old German guy does it.

Cheers
Engelbert

That's a good tip, I can see how the extra reducer would give the paint some more time to flow out.  I'll try it out with the clear on the headlight covers.  I wonder if it would work with a metallic base coat.  I know people have a difficult time getting metallic paint to cover consistently, resulting in visible striping.
72  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 18, 2016, 02:23:17 PM
Well, made some more progress over the long weekend.  Jeff helped me get all the body panels back on the car and I got to use the polisher Danielle got me for Christmas.  The car looks pretty good.  I did realize that I forgot to paint the headlight covers, so I'll have to do those soon.  I can start reassembling the car now, all the trim, interior and top.  Hopefully it runs when I'm done!

Here is the front end with all the mechanical parts back in place



And the panels back on.  The bumper doesn't line up perfectly, but it's pretty damn close.



It was a lot easier to put the dash in without the windshield in place




So, I definitely learned a lot spraying the car.  One thing I learned is that thin coats of clear = massive orange peel.  You can see the fender and the hood here.  I shot the fender with relatively heavy coats of clear versus the hood.  This is before polishing anything, I almost don't need to touch the fender, but the hood is horrendous.



I saw online that you can use a denim polishing pad and compound to remove orange peel, so I wanted to give that a try instead of wet sanding.



Here is the center of the hood before



And after




I also had to do the trunk, which I sprayed in the same batch as the hood.  I decided to try wet sanding and then polishing.  I used 1200 grit, then polished with the denim pad, and then went over it with a light foam pad and polish.  This was faster than just using the denim pad, though it was easy to sand because it's flat.  The hood would have been more difficult.  On the panels where I had a reasonable amount of orange peel, I just used the denim pad and the car came out well.

Polished with the denim pad



After the foam pad




I'm happy with the way the car is turning out.  Hopefully I can get it fully assembled and running in the next weekend or two.

Damn, glad to hear everyone is alright.  That's pretty terrifying sounding.

I've heard great things about Burleigh's.  We took the Porsche there when our insurance company didn't think it was totaled and had them dig into it further.  They were very easy to deal with.  I think our 911 was the crappiest car there, which says something.
74  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 04, 2016, 06:55:57 AM
Yeah, I'll have to spray the floor down next time just to wet it.  That makes sense.  I've got an okay desiccant filtration system and the air line system is setup to pull moisture out (aftercooler, lots of copper pipe).  I didn't see any fisheyes, so hopefully I'm good to go there.
75  General / Autos and Autosport / Re: Hit a deer in the Miata at 50-60mph on: January 02, 2016, 11:35:20 AM
Well, I've made some more progress.  I got the car in paint and am almost ready to start putting it back together.  Just need to clean up the weld seam up front.  I'll do that today or tomorrow.

I used the room in the middle of my garage that is ~20'x20' as the paint booth.  I sealed all of the openings to the room the best I could (caulked the ceiling and paneling joints, put some weatherstripping on the double door, sealed around all the electrical wires) and cleaned it several times.  I knocked a couple holes in the walls on either side and put some air filters on them with box fans blowing outward.  I also put two air diffusers in the ceiling and rigged up this device to blow air into the room.  It does a great job keeping the air clear while I'm spraying.  Unfortunately, it also does a great job stirring up any dust (or lint from my mop) that's on the floor.  I may need to get a speed controller so I can slow the fan down.



I also built a fresh air supply out of a $25 firefighter's mask, a spare Miata heater blower hooked up to a power supply, and a bunch of pool hose we had.






Thankfully, all my small cars (Miata, Civic, Cobra) fit through these double doors.



Jeff came over and helped me prep the plastic parts, like this bumper that has been repainted a couple times already.



I had already sprayed the self-etching primer, so next I put on 3 or 4 coats of primer surfacer.





After that, I moved everything back out and wet-sanded the whole car.  I used some guide coat to help me, it's the black powdery stuff in this pic.



I sprayed gravel guard on the bottom part of the car, like they came from the factory.





After that, I moved everything back into the room and sprayed the base and then clear coats.  You can see the clear coat adds the gloss (second pic).  The base coat paint is much thinner than the primer or clear and I put the first coat on too thick and got some runs, so I had to wait for it to dry and sand it down some.  I ended up using 4 or 5 base coats and 3 or 4 clear coats.  I also shouldn't have used the plastic to mask off the car.  It is easy for the dried paint to flake off and blow onto the wet paint on the car.










The paint isn't perfect, but it certainly looks a lot better than before.  I'm happy with the way it came out and am really happy I painted this before the Cobra.  I learned quite a bit and know what to avoid doing next time.
