ERMA/SIAM Update and new History and Photos

Thank you, Jacques Dresang, for his research on the Tanner H-Mod’s he just acquired.  The Tanner T2  driven by Frank Isaacson, named the Lyne Special, who also drove and owned the ERMA/SIAM.  Jacques reached out to Franks daughter, Eve Prebil and she was gracious to share some history and valuable information on both the Tanner and the ERMA/SIAM

The ERMA/SIAM was built by Purdue students between the 1953-1954.  Frank Isaacson was a student at Purdue graduating in 1955.  Eve suggests that he may have been involved in the build of the ERMA as Frank had “built his first car age 15”.

Subaru-Brat Water Pump Sketch’s

After finishing the installation of the Subaru-Brat water pump on my H-Mod, SIAM-Fibersport, I was asked for the sketches I used to fabricate. So I went on a massive hunt on where I got these sketches and best I can figure was a 2007 Post in the now defunct Yahoo Groups H-Mod forum that Nat Sherrill, Marty Stein and others managed. Best I can tell is that Marty and Franklin Rudolph were involved in posting these sketches. If I learn otherwise I will correct.

So along with pictures of my installation on here are the sketches I used.

Good luck and share your completed photos.

———-Reprint——-“Retrofitting an Austin Healy Sprite Clutch in a Crosley”

In my quest to upgrade the SIAM with a newer gearbox, the Sprite Ribcage Transmission, I came across this article in the “Tin Block Times”. Tim Foster gave permission to post this article for others that maybe interested in doing this for Crosley or Crosley powered H-Mod.

Originally published in the “Tin Block Times ” Volume 1, No. 1 Winter of 1986 author Dr. Bob Graham and additional info added by Glen Brynsvold after he completed his upgrade to the Crosley-Scorpion

SIAM Update

Featured

It has been a few years since real work on the SIAM was done. The Elden’s keep the shop busy but with this pandemic and waiting for some racing parts I decided the catch up some SIAM work.

First I rebuilt the the Crosley Steering box with new bushings and seals from Service Motors, https://www.servicemotors.net/. Then I tackled the fun job of the Crosley front axle King Pins. The King pins required some tooling to allow reaming to fit and maintaining the alignment of the top and bottom. So I built this reamer tool.

5/8″ Adjustable Reamer with Extension

A project I started December 2017 was to convert to a Subaru Brat water pump. I had previously made the pulley, https://lchrestoration.com/category/1954-h-mod-siam/. Now I needed to make a bracket to hold the pump and complete the plumbing.

Subaru Brat Water Pump Bracket

The complete installation:

Subaru Brat water pump installed and back plate fabricated.

Finally, I reinstalled the Crosley front axle. The SIAM is right hand drive and as such the front axle is turned around 180 degrees. That in itself sees to be okay. But I found that the front friction lever shocks were binding up the front leaf springs. So I built a new mounting system allowing the lever shock to move without binding. Wish I had taken a picture of the original but here is the new.

Another thing found was that castor seems off with reversing the axle. Will update this later as the work isn’t done. The following picture shows a castor adjustor on the Crosley Fibersport waiting for restoration here. What is weird it is on the top of the leaf spring and I’m not convinced that it actually adjusts. I would think it belongs on the bottom of the leaf spring. Once the wheels are back on the ground I can confirm all of this.

Crosley front axle castor adjustor?

Will update soon the castor resolution soon.

Adding the Subaru Waterpump to Crosley Engine

Had seen others talk about swapping the original generator driven water pump with a 1980 Subaru Brat 1.6L pump.  That eliminates the generator which for an H-Mod isn’t entirely necessary.  On my engine I had scored a generator eliminator jack shaft.  But still wanted to eliminate the Crosley water pump.

I had seen instructions on the web and some preliminary drawings but until I started turning metal did I fully understand the process.

Parts List

1980 Subaru Brat 1.6L water pump Bech and Arnley #   Picture of pump

Champion 400A pulley- Tractor supply or most hardware stores

6 ea 6-32-1/2″ socket screws

5 ea 1/4-28-xxx hex head bolts and lock nuts/washers

3 ea 5/16-18-5/8″socket head or hex bolt/ washers

3″x2″-1/4″thickness-3 ” long Aluminum angle stock

First was to take the Champion 400A pulley and turn the center out of the pulley to allow its flat back face to attach to the front of the Subaru pulley front.

For my pump the diameter of the Champion 400A to fit the pump was 2.015″.  Faced the pulley to ensure flat mating surfaces.

Then Turned the back half of the Subaru water pump off to eliminate the unnecessary material.  I turned down to the pulley bottom.  Beware I turned this on the lath by holding the water pump body still, using dead center on the impeller shaft and turning off the pulley.  The pulley is cast steel and very soft in my situation.  “TAKE ALL SAFETY PRECAUTIONS”

 

 

Next determine a bolt circle on the inside of the “Champion 400A Modified” pulley and the Subaru pulley to allow 6ea 6-32 by 1/2″ socket head crews to be drilled thru the Champion 400 A pulley and taped into the modified Subaru pulley.  For my application that was 2.45″diameter.

Next fabricated from 4″x4″ by 1/4″ thick Aluminum plate a backing plate for the water pump.  For my application I used 1 1/4″ diameter tube as the outlet to the Crosley engine.

 

I haven’t finished this yet so decided to publish interim steps.  Will edit once installed into SIAM.

1954 SIAM Restoration Process-As Found

SIAM 100 Annotated

This picture was taken by Don Suiter in 1997 when he bought the car.  No work was done until 2004.

Note that the rear firewall is just a canvas cover.  The rules sure have changed over the years.

What was interesting on the SIAM when I got it was all the interior gearbox covers and driveshaft aluminum covers were 20 gauge metal loosely placed into position.

 

Rear canvas "firewall" removed exposing the ladder frame, roll bar, gas tank. Let me ask you: Trust that roll bar? Rear “firewall” canvas removed exposing roll bar structure, really?

SIAM Presevation Round 1 Done

So I have working on the SIAM pretty much non-stop since Dec 2015. Today I declare it ready to go to the Crosley National meet in Waueson, OH in July. My path of Presevation is to take stages or I’ll never finish. This gives me the motivation to get going again. 

SIAM is a custom chassis built by Purdue Engineering students in 1954.  Was re-bodied in 1956 with the John Mays “Fibersport” body. 

I got the car in 2004 and began the preservation. Work stopped to build the Elden Formula Ford’s. Now SIAM is running and driving short distances.  

Watch for more history and info.

Comparison of E.R.M to SIAM Rear Suspensions

Was wandering internet sites working on H-Mod history.  Looking at the pictures on Cliff Reuter’s website again:

http://www.cliffreuter.com/etceterinihomepage.htm

Specifically page on ERM or E.R.M

http://www.cliffreuter.com/etceterinihmodcarscliffreuter.htm#ERM.

I noticed the rear suspension is very similar to the SIAM rear suspension; lever friction shocks, cantilever rear spring, etc.  Was wondering if there is a connection? Anyone help here?

Did ERM have front friction shocks also?

ERMA/SIAM Fibersport History 1954-2016

Having gone through many notes from Harold Pace and Mark Brinker, Steve Hawxhurst and many others I am publishing what I believe is the history of the “ERMA” to “SIAM” as I now know the car.  If you have any comments, corrections please advise as I want to be accurate but not lose any history.

ERMA-SIAM Fibersport

Purdue University students as a class project built “ERMA” in 1954 a H Modified race car. They used a John Mays “Fibersport” fiberglass body.  E-mail Bill Mays to Larry Haynes:

“5/30/2004

The body seems like original. I was in the USMC at the time Dad sent that body out but remember everyone talking about their project (from1956 0n). Do remember them saying it had a trunk opening. The light mounting was optional. We moved them out of the grill opening to reduce chance of over heating. Ours were just openings cut in the body and then lights mounted on attachment to frame……”

“5/31/2004

…..The body is from the original mold made in 1955. Is it right hand drive, if so, think it is the only FiberSport that is (editorial: right hand drive). Sure brings back memories!”

Car had a Crosley engine, “Standard” 4 speed transmission and Fiat 500 rear axle and drum brakes, Crosley front axle and Crosley drum brakes.  Frame is a 3″ tube ladder frame.  (Pictures to be added soon).

Frank Isaacson was a Purdue student and bought the car. At the time ERMA was Orange #33. (Is this “ERMA” in action?)

SIAM #33 Archive-1

“ERMA” first name for the car from Purdue was sold to Frank Isaacson. Did the name “ERMA” come from the “entity” “Experimental Racing Motors” established in 1954 so the Purdue students could buy parts wholesale? Note the checks used to buy parts provided by Chuck Reupert.

Purdue Univ checks etc for SIAM build

Note: Tim Foster has heard rumors there were two cars made at Purdue”

“This is interesting news since I didn’t know there was an earlier iteration!

This came from a guy named Bruce Boschek who had helped Norm Esau wrench on his Crosley Nardi (now owned by Don Baldochhi) back in the early sixties. turned out that he had met the Mays family (Fibersport builders) back in the day and knew of the SIAM- and he says that the students who built the SIAM built at least two diferent versions of the car – they started from scratch after the first chassis turned out to be ‘slow as a turnip.’ This matches pretty well with a statement by the late Bill Mays about the first outing of the SIAM.”

https://groups.yahoo.com/neo/groups/HMOD/conversations/messages/6464

The web site “Racing Sports Cars”, www.racingsportscars.com,  show result’s for Frank Isaacson from September 6, 1958 to Sept 12, 1959, under the entry name #33 “ERMA”

http://www.racingsportscars.com/driver/results/Frank-Isaacson-USA.html

The race records show that Frank Isaacson raced the car until 1959 when ownership transferred to Warren Meyer.

Approximately Jan 1961, Warren Meyer sold “ERMA” to Steve Hawxhurst, car was renumbered to #35 and painted Blue.   On “Racing Sports Cars” records show one race June 25, 1961 under the name “SIAM Special”. SIAM #35 Archive-2  Is this a picture of Steve Hawxhurst driving “SIAM Special” #35?

http://www.racingsportscars.com/driver/results/Steve-Hawxhurst-USA.html

The name change (“ERMA” to “SIAM” is confirmed by Steve Hawxhurst’s, son by the same name.

Steve Hawxhurst e-mail to Larry Haynes, 12-5-2010

“I’m Steve Hawxhurst’s son by the same name. I will have to do some digging through his notebooks to see if anything comes to light. I can tell you that it was my father and not the original Purdue builders that put on the “SIAM” badge. I have no idea where he got it from but the idea that it came off an old refrigerator or washer seems dimly correct in my memory.”

In 1962 Charles (Chuck) Reupert of Milwaukee, Wisconsin bought the car from Steve Hawxhurst. Who then sold the car to Jim Wisniewski in Milwaukee, Wisconsin in 1964

The car color was changed to Green and #41 and renamed “ASP” noted in a letter to Charles Reupert in 1964. Siam pictures 1997-1 DSPictures from Don Suiter when he bought the car from Jim Ash.

In fact, Steve Hawxhurst requested the SIAM nameplate returned in 1964, “as the only one I had.” Editorial. Wish I knew where the SIAM nameplate originated.  An internet search over the years hasn’t led to a definitive answer.

SIAM Emblem 2This is a scan of the metal “SIAM” nameplate. Note: During Restoration I was able to confirm the car colors: As found, Green #41, next color was Blue and under that was Orange. No gel coat on the fiberglass, as found.

Sometime in the 1990’s Jim Ash of Ixonia, Wisconsin, bought the car from Jim Wisniewski. A 1991 letter to Steve Hawxhurst’s son talks about the history of the car.

Steve Hawxhurst son letter 1991

In 1997 Don Suiter of Colorado bought the “SIAM” from Jim Ash and transported to Colorado from an e-mail from Ray Jones in Colorado describes this time frame:

“Larry,

I found your message on the net, by pure, happy, mistake. I almost bought the Siam from the broker in Wisconsin (Bill Schley).

He was offering a 1947 Hillegass midget (this was in about 1994) and the Siam at the same time, and I wanted the Hillegass worse, but the Siam came to Colorado via another RMVR member, Don Suiter, ( I told Don about the car, he immediately went to Wisconsin to pick it up, literally the next day) .Don later sold the Siam to Larry Coldren. Larry brought the Siam to Second Creek to share a pit space with us in 2001 or so, and the car was an outrageous hit. As you know, Larry got involved with restoring the Elva sports racer. Larry (who is a very dear friend) wanted to keep the car “in the family”, and offered it to me. My wife and I race, among other things, the Formula 250 Emeryson, so we understand “different” cars.

From what little we know and recall about your car, it’s a 1950 or so iron block crosley, coupled to, as memory serves, a Triumph (mayflower?) rear end, utilizing, again from memory, a Fiat transmission and Fiat brakes. According to Bill Schley, when he found the car, it was in a barn, serving as a pallet, and had hay bales and feed sacks stacked on it. That would certainly account for the distortion in the body panels. From what we have learned, the Fiat transmission was commonplace, as the Crosley transmission is pure crashbox, and the Triumph rear end was popular, due to the 4.56 or 5.1 gears availble.”

Ray Jones

Update: “Got to thinking about it afterwards, I had my components reversed, Triumph tranny, Fiat rear end.”

Ray Jones

Don Suiter sold “SIAM” to Larry Coldren of Colorado who then sold to Mark Brinker/Harold Pace in Weatherford Texas in the 2003 time frame.

When Mark Brinker and Harold Pace got the car they decided that neither would fit in the small “SIAM” cockpit so sold it to Larry Haynes in Santa Fe, NM in 2004, where is still resides and is undergoing restoration. Note:  Larry Haynes may not fit either!

Additional info on SIAM History

Well if I read and comprehended half of what I read I would be so much better at this.  The “Class H News” of June 1959 talks about the Wilmont race of May 17th.  Noted is “Frank Isaacson has his car looking better and going well”:

Class H News June 1959

When I did a search of “Frank Isaacson” on:

http://www.RacingSportsCars.com, (permission granted by http://www.RacingSportsCars.com)

Frank Isaacson on Racingsportscars, ERMA on Racingsportscars

I found the correlated information that May 17, 1959 Frank Isaacson was entered as #33 “ERMA Special”.  He finished 5th in the preliminary race and 6th in the race.  Is this a picture of Frank Isaacson?  Right car#.  We also know that when you see the Steve Hawxhurst info below the car was #35!SIAM #33 Archive-1

Frank Isaacson drove the “ERMA Special” from 1958-1959 when he switched to a “Lyne Special”.(per the records on http://www.RacingSportsCars.com)

I think this is solid evidence with other documents and interviews with members past and present that the car built by the Purdue Students was originally “ERMA Special” and rebadged by Steve Hawxhurst to the “SIAM Special” noted by Steve Hawxhurst’s son and also verified by race results:SIAM Emblem 2

S Hawxhurst-SIAM on racingsportscars

This shows that Steve Hawxhurst drove #35 SIAM special on 6-25-1961 at Milwaukee finishing 1st in HM!  Is this a picture of Steve Hawxhurst?  Right car # and now “SIAM Special”! SIAM #35 Archive-2So I think we are starting to understand the history of ERMA and SIAM H-Mod.  Watch for more info to follow.  Larry
