Title: Gasket Scan Library
Post by: Hoosier Daddy on Dec 30, 2012, 07:55:22
A member on another forum posted life sized scans of his gaskets. I thought it would be a great idea to start a library of scans for DIY'ers to use as templates for making their own. Since many have access to flat bed scanners either at home or at work, and we have such a diversity of engines here, I hope this will grow to be quite extensive. Next time you buy a gasket or set simply scan it and post it up here.
I started the list off with the 76 SOHC CB750 units he submitted and I just picked up the OEM Alternator Cover, Clutch Cover, Left Crankcase, and Oil Pan gaskets for my  DOHC engine from Mother Honda. They might just all fit on my 8 X 11 flatbed scanner... I'll be scanning them and adding to the list before installing soon.

List the year, make, and model at the begining of the post, if you can add the actual OEM part number (not aftermarket) onto the scan itself. That will make it easier for others to find their applications.
I will try to maintain a list here of what has been added with shortcuts to that post.

Might be a good idea to include the model year in the description to aid searches.  cb750F 75-78 or cb750F 79-82

YES!
List the year, make, and model at the begining of the post,
As long as the poster lists it I'll include it in the description... since I don't want to be responsible for application cross-referance.
As I said, I know mine will fit 79-82 DOHC CB750 (all) and will list them that way once entered... but as for the original listed 76 CB750F I didn't want to risk including a wrong model or year so I left it as submitted. ;)

I've always wished that I have a large scanner and a vinyl cutting machine to make custom gaskets. I work with oddball vintage bikes often enough that gaskets can sometimes be difficult to get. I am not interested in the labor intensive process of manually cutting out gaskets, but if I could have a computer controlled cutter/plotter do it, I would be like a pig in shit!

This could be a great resource. I hope it takes off. Just got some fresh gaskets for my 78 GS750. May have to scan and submit them.

Please do RoadRash!
And yes AlphaDog, if I could just load gasket paper in my printer I'd be happy!

Hey Hoosier,

I think maybe you found my post over on hondatwins - I post as "CB650" there.  I'm trying to find a good way to share the PDF I created, but in the meantime here's a link to my post.  Feel free to throw it up on your Google docs.

Hey Hoosier,

Nope, your post was about a week after I started this! (great minds...) But thanks for the contribution, that link oughtta work just fine. I could go right to your scans. But, I am a member there as well so if a "non-member" to  Hondatwins.net has issues we can work on linking direct. (While I was there I pirated the CB450 set ::) )

Sorry Ncstatecamp, not goin there, Towards the begining I said...

...that's why I wanted the OEM parts numbers included. That way you can cross referance them to see for yourself. If this grows to the extent I hope it does, there is no way I could know what all fits what. :)

Also, if you would get a thickness of original material w your digital caliper.  That would be helpful

Love this, And I think not only gaskets but decals, manuals and anything similar for old bikes should also get digitalized for future use, that way nothing will get lost and never be replaced. But that's a bigger project for the ambitious.

I have new OEM gaskets for the Yamaha XJ 550 (81-83), I'll scan them and make them in a vector format so they are ready for the cutter.
Title: Re: Gasket Scan Library
Post by: mikewerx on Feb 07, 2013, 11:11:03
What would be the best way to cut them?  I have a decent sized laser cutter, would that be safe?  And where is the best place to get gasket materials?
Title: Gasket Scan Library
Post by: Ncstatecamp on Feb 12, 2013, 04:49:18
Would scanning the object that gets gasketed help? Like could I scan the valve cover for the cb work and just cut that profile?

Post by: Scruffy on Feb 13, 2013, 00:48:05
NC, easiest way to cut your own gaskets... Place the part on the paper/cork, tap it down with a rubber mallet. Part shape will transfer to the gasket material. Cut and hole punch as needed, use an exacto knife and I like to use sharpened cartridge cases as hole punches. I used to use black fountain pen ink as the transfer medium but it has gotten expensive. You can lightly oil coat the part and use it to transfer the shape, but, the gasket may not seal right, many paper gaskets go in dry, so do most cork ones. You want them to swell up after they get installed, not before.

You can rub the part with charcoal for transfer onto light colored gasket stock, but again, it may not let the piece seal up properly.

I might have to give this a try... thank you very much

eh.. dont wanna rain on the parade.... but when you scan, upload, download and print an image on various machines with various software, it's 99% of the time NOT the exact same size. Kinda important with gaskets right?

Therefor, i think its handy to scan them on top of a rasterized piece of paper, like this:

(http://download.chip.eu/ii/205530924_5fd24be3f5.jpg)

Ofcourse you'll have to WRITE ON THE RASTER PAPER what the scale is. DO WRITE it on, as a post might get deleted, but a picture will stay forever, with its scale.

What do you guys think?
Title: Re: Gasket Scan Library
Post by: Pod70 on Mar 05, 2013, 13:31:52
I hate agree with Bert Jan, but it is very likely that the print out will be scaled in some way and not fit. We have this issue at work trying to print out scale drawings of buildings we are working on. This is why all technical drawings state not to scale from the drawing as they will be out of scale-sorry

Post by: davidgwells on Mar 05, 2013, 14:37:37
The scans shouldn't be scaled as long as the user leaves it at 100%.  If you have access to adobe illustrator that program can print full scale and span pages if needed.  I'm sure there are other programs that will too, illustrator is pricey.

1mm is to much differnce for a gasket... Besides, i have never seen 2 printers of different make and model print the exact same print. I went to artschool (university) for 4 years and work daily with CS and pricey printers. It's always a pain.

Post by: Hoosier Daddy on Apr 05, 2013, 09:16:48
Damn... Wouldn't a .pdf instead of a .jpg or .gif take care of this? Or is the issue with the scaling due to the individual printer?
Title: Re: Gasket Scan Library
Post by: Bozz on Apr 05, 2013, 12:16:20
There will always be issues of scale when printed, as it is a printer driver level issue.


One way to minimize this (not eliminate, but minimize) is to include a scale object in the scan.


A little grid or square that has been confirmed with a ruler with the size of the object/pattern written on the image.


That way the image itself contains an internal scale reference.  Print out the file and measure the scale object within the image and see how off you are.
Title: Re: Gasket Scan Library
Post by: Worst cb650 ever on Apr 05, 2013, 15:50:38
Yup, I put a ruler on the scanner glass with mine.  Still didn't help when I didn't set the scale to 100% to print it out. 

Remember that scene in "Innerspace" where the bad guys get shrunk down to about 4' tall?  Yea, like that.  Protip: lay a ruler on the scan on the image of the ruler in the printout.

Damn. I wish I would have seen this a few days ago, I just installed most of a full KZ400 set. I think it's a good idea, and with a scale in the scan you should be able to tweak the print/scaling settings to get it right. I'll try to get the ones that I have left.
Title: Re: Gasket Scan Library
Post by: Hoosier Daddy on Jun 02, 2013, 08:38:05
Did this a while ago as a test at home after realizing the scaling issue myself.
So here is a test for you. Since it is an attachment you should be able to "click" on it and see it full sized... then print to test.

I just got new gaskets for my CL175 to fix some minor oil leaks, so I thought I'd throw them up here for the good of the order. The dimensions of the graph paper when originally scanned were 1 inch (bold lines) and 1/10 inch (light lines), but when I printed it out it was slightly off. So, I'd recommend printing a tester then adjusting to scale for accuracy in your printer settings.

This is aa great idea!  I started scanning gaskets about 2 years ago and was planning on posting them somewhere.  The scaling problem concerns me, I haven't tried to make a gasket from my scans yet from pdf but my ultimate goal is to reproduce them into vector drawings for using Inkscape or Adobe Illustrator for use in laser cutter.  Has anyone started doing this?  I hope to start soon on my XS400 gaskets unless someone already has them available in .AI or .SVG format. 

Cheers!

Gasket King (http://www.gasketking.com) will make gaskets from a scanned image.  I had them make a couple of float bowl gaskets for me a while back.

They already have a large library of gaskets for old bikes, so there a decent chance they may already have the gasket you need
