Engine blueprinting worksheets

AlteWagen · Troll Joined: February 23, 2007 Posts: 8501 Location: PNW

Since i always just scribble notes on small sheets of paper just to loose them and remeasure, I decided to make some worksheets that I can keep for future reference and to give to customers when I complete a build.

There are a few things that I remembered I left out and have added in to the original document but I would like feedback for more stuff I forgot or things I should remove (retainer weight??). Think if you were to have someone build you an engine, what info would you like to see?

Thanks

Update - This is now on the site in PDF Format.

Very nice!
Anyone who assembles an engine should have one of these.
Definately beats the binder paper i've been using!
Thanks!

Well i consider myself a "assembler". I've assembled many engines with great sucess, but I definately don't have the smarts of Raby, Chico, ect. I consider those guys builders!
But i still take the time to measure everything (as should anyone assembling a engine) and write it down.
But derluftwagen did an excellent job with his spreadsheet! I know it will make it easier for me now! Cool

I am waiting for more feedback to finalize the sheets. Once completed I will send them to EB to post as a PDF or what ever format he recommends.

There are a few things not on these JPEGs like:

Quick summary
Installed deck height/head cc/shim stack/copper gasket table
Final end play shim stack measurement
Quick reference torque table
Solid rocker shaft shim measurements
Rocker stand shim measurments
Actual valve lift measurement (installed specs for rocker arms (true ratio))
Sand seal type check boxes
Flywheel dowell pin size/lenth
Gland nut type/size and final torque
Pushrod tube type/size/seals

etc...

Im sure there are other things Ive forgotten so I need some "builders" to chime in.

Thanks again!!!

too much writen fer me.but nice work, as some realy need that kind of stuff and some want that kind of stuff, then there is the ones who,have to have that kind of stuff(ocd, witch I have but not that bad).I do how ever have stack sheets that take the big part of guess work out of figuring the stack& what will be needed in theroy for each combo,just add it up.(I havent checked the AA cylinders&pistons for the sizes I only have 1 set of 92b's from them)

I guess I am ocd when it comes to putting together an engine for a customer that will drive their car daily to work!!! Even stock builds need some added attention as the cores are 40 years old and have been through hell not to mention china parts.

That and the fact that most machine shops are using 50+ year old machines that MAY get calibrated every 20 years or so. By taking measurements before any assembly you can tell if the line bore is crooked or the crank is warped.

Another reason I put these together is for the novice builder. Even if they do not know everything (who does) it will help them learn what to look for. How many posts do you read about seized rebuilds or junkyard builds that are all mis matched? If you want to use used parts just measure the parts, and 90% of the worry is gone!

It would be nice if it was a word file or something you can add the numbers to.
I find when I do a paper print out of something like this it either ends up with assembly oil, or sealant,or lunch on it so it would be nice to print out a copy with the info entered and readable.
Like this one I have been using:

only trouble is if you scroll down to the total when the wife is looking over your shoulder........ d'oh!

Looks good, nice job. I have a spreadsheet I put together for mine, but yours looks more professional. Only thing that might be nice is a before/after weight on pistons and rods. Mine were all over the map (401 to 406 grams!), and some people might want to know how close or far off they were.

Excellent list; significantly more detailed than the log sheets I devised 10-15 years ago. How about a space for each major component, as to its origin/where you bought it? This was significant for me, being a home hobby builder and finding parts at swapmeets or buying them new.

After posting my response and viewing the lists again, I realized you do have several lines' space at end of each section for such "notes'. Smile

Also, how about
- in which car was the engine installed (customer name, or type of VW and when)?
- The case sealant (to monitor if the engine leaks soon or not),
- initial carburetion,
- exhaust system?

I remember these sheets when I raced 1/8th scale R/C buggies...tedious work getting shit dialed then simply refering to your tweak sheet for various settings/adjustments. There was even an empty block for our nitro engines...shims, glowplug heat range, pipe, exhaust manifold, clutch springs, clutch shoes.....it was insane!!!! Laughing

Word or EXCEL document would be awesome then people can print them out as need be.... OR modify for special circumstance...

IF you make a Word or Excel file I can host them for download on my site, on "Technical Links" page

http://www.mydune-buggy.com/

Would also host PDF version if it were available....

It's too bad I can't see photobucket images from work but I have my own sheet in Excel. Derluftwagen, any Chance you want to host your on thesamba instead of photobucket?

Wow, this is terrific. Do you happen to have it in an excel sheet?

AlteWagen · Troll Joined: February 23, 2007 Posts: 8501 Location: PNW

like I posted earlier, still working on the final version and when complete I will make it a PDF and post it here for all to use.

Currently it is in a word doc and is in a fillable form and will offer it in both versions if possible.
