The majority of responses here are asking for something simple & you have planted your feet in the sand and said no. Just add a rule and make everyone happy, you'll feel better after doing it.

I want to thank you for going through the process of documenting, as well as neatly producing a How To on straightening a warped carb top. I know how long it takes to do it; I've done a few How-To's. I'm hoping this finds it way into the How To sub-forum for future reference...with or without the measured reference.

As with all posts on this (or any other) forum, they are open to review and critique. In other words, if you put it out there, there are bound to be others who will have a suggestion or comment.

Whether you agree with the comments or not is your decision.

Thanks again for your efforts. :coffee:

I don't have my carb or my jig handy to compare, but I had a plate machined to a drawing I'd found here:

http://farmallcub.com/phpBB2/viewtopic.php?t=24466

I didn't verify measurements on my carb or after I received the plate as I was at work (measure twice, cut once?). When I attempted to mount it to the carburetor, the hole for the carb throats was slightly off and required some more machining on a friend's Bridgeport. Didn't give it a second thought as I now have one that works perfectly, if a little ugly.

Just wanted to verify my original assumption that there were only two styles of carb (IH and Zenith) and that my flattening jig was probably mis-measured or machined.

My comment, of which you asked for, is not questioning your method of making the jig. It is a suggestion to mitigate the chances for error. It's not to make this into a dimensional drawing and have a precise measurement between all the points, it's to make sure when I, or anyone prints this out, that when I start fabrication following your "no measurement needed template" I don't waste time, effort, and material, because some glitch printed it at 3x3 (exaggeration for clarity). Just because you printed it on four different printers doesn't mean the other 7 million combinations of computers, operating systems, and printers will all print it to actual size. Again, it's just a simple step to verify that the template you printed is actually "actual size".

You have included my suggestion already (the 4x4 square box) if you identify it.

After printing, verify that the box around the template is 4" x 4" before continuing.

All it would take is a simple school ruler or a tape measure. Since you reference 12 different measurements in your instructions, including some decimal ones, I think you must expect everyone to at least have a ruler or tape measure.

I do commend you for taking the time and effort to create this whether or not you incorporate any "second set of eyes" comments.

It will, I'm just waiting for all the comments come in.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

See first post for updated drawings.

Thanks for all your hard work Orv!

FYI: Notes from Orv:

I have reviewed members many forum comments as well as private messages that I received and have modified the files to include those that I considered most appropriate. The template was expanded to include all specific location dimensions with the exception of the mounting holes. Those are just shown for general placement only. The builder will need to follow the procedure as noted in the EZ how-to or procedure file for accurate placement and drilling of the mounting holes.

The template went from a very simple and basic drawing to one that is more complex. I can only hope that the less technically experienced forum members who interpret this dimensioned file will not have difficulty using it. Making this too complex by displaying a lot of dimensions was not our original intent.

I would welcome any comments you might have if you see any more modifications.

I printed the first posting and made made a jig from it. It was easy and straightforward. I did not follow the step by step instructions. The jig came out very nice. Used an old piece if 4" x 5" X 0.25" steel with the print taped to it. Took out two carbs that have been setting in a drawer since 1986. I know one needed a new float and had stopped by Steiner and bought a new one along with two rebuild kits 4 or 5 years ago. When I placed the top of the carbs on the jig neither needed straightening.
