Applying decals

When I was youg, I was into car models, AMT 3 in 1. Occasionally, I would apply the water transfers, which were easy to do with simple slide on after making them wet. Well that was like 30+ years ago., Today I am faced with applying vinyl transfers and at a loss how to do it easily.
The issues is the curve of the tubes and how to temporarily anchor the transfer before applying. The transfers in question are large panels for the Bottecchia seat and down tube. I have a good idea where they need to go but not how to get them there. The others are small enough that I believe I can transfer them easily. I think they should go on last after placing the large panels for desired spacing. I have the directions that include using masking tape as an anchor but no detail beyond a picture and then removing the backing Do I trim the vinyl to the edge all the way around so I can anchor and easily remove the backing? Do I start by anchoring the long edge, which would be on the back side of the tube?

So what is your process?

Here is the frame in question

I’m no expert but if it were me, I would mock the decals in place with a couple of small pieces of painters tape. I would then apply a long strip of painters tape to create a reference line to butt the decal’s vertical edge to. Once the decal application is underway, the reference tape can be removed and the decal application can be completed. You may want to research the use of water mist to facilitate minor alignment maneuvering.

I"m a bit lazy to write all the steps necessary to get decals on straight where they belong. It's a lot of detailed writing and editing to make sure the entire process is clearly understood. Call me, I'd rather tell you over the phone. PM or email me if you don't have my #. The process starts with the right tools. I use a section of 3/4" aluminum angle I bought at the hardware store. This is a guide when placed along a tube for making sure a decal is straight without climbing up or descending. The other most valuable tool to me is a half section of tube with a squared end. This is for getting decals straight across from each other and/or not being twisted. For example checking that a seat or head tube decal is not crooked. Since I am a frame builder/painter I have just the right size tubes in both wall thickness (0.058" is best) and diameters. For example if your seat tube is 1 1/8" in ø than a 1 1/4" OD tube with a wall thickness of 0.058" split longways in half will fit perfectly over your seat tube. Before I cut the tube in half and file off any sharp edges, I square the end of a whole tube on my belt sander or use my lathe. Tubing with thinner walls can work okay too.

The 3rd and 4th tool required is masking tape and a pencil. The angle and half tube can help you place your masking tape in just exactly the right position before marking on it to show where the decals need to be placed next to it. You will also probably need to make tiny marks on your decals (before taking off the backing paper) to indicate centers or some other reference in relation to the marks you put on your masking tape now on your frame. Once you have those tools in your position, call me and I'll give you much more detailed instructions. Or maybe someone will post that has more patience writing than me .

SJX426,
On the vertical ones on the down tube...always the most difficult to do.
1. First measure the length of the decal
2. Cut the decal from the sheet leaving the paper on...leave enough space at the top and bottom so that you can handle the decal without leaving fingerprints when later positioning it.
3. Place the decal with paper backing on the tube and mark a centerline on both the decal and the tube, you can use a dot no need to draw a line....I use a wax pencil, again you only need a small mark to center the decal on the tube.
4. Carefully peel the decal from top to bottom (the extra space left on the edges will facilitate the placement)
5. Start at the top by lining up the centerline dots....position the decal and eye up with the bottom line and you are good to go.

Do a dry run with the paper left on in order to get the feel of it, the directions make it seem more difficult than it is.
Good Luck, Ben
Looks like you have another way to do it posted while I was typing...see which you prefer, not that difficult it will work out

Doug Fattic xiaoman1 Thank you both for responding. Looks like the approach is the same just different "tools". I am thinking that the long edge needs to be applied then wrap the rest around the tool. Two risks come to mind, the "twist" and centering of the decal at the center both in length and width. I get the half tube tool. Good overall explanation, Doug Fattic .

The vinyl is already cut without cutting the backing. So I assume that if I am starting along the length to apply, the extra space would be along the top and bottom.

I cant see trying to place the vinyl any other way, unless it tis to mount it along the center marks of the middle and hope to apply the rest without wrinkles, or is that where the extra space is?
The instructions do say to use a soap water solution prior to application. I thought I would level the bike first along the top tube then use the level to mark where the DT decal starts in alignment with the ST decal. Most of the pictures of this bike with decals shows the back side of the decal about even with the brake bridge. the front of the decal would then be slightly higher as it wraps around the tube. the Carnlelli is about half way between the TT and the ST decal edge. The Olympic rings are still on the bike but mostly gone.

Use the wet method, just like you did with car models years ago. VeloCals makes some premixed application fluid that works quite well on vinyl stickers. I’ve also made up my own, using 3Ms guide for wet method application. Doing it this way is similar to applying water slide decals, except you peel off the backing, then liberally coat the decal with the wetting fluid, also liberally coat the surface you are applying it to, this allows you to move the decal around till you get it just right. Then pat it dry with a towel to remove the moisture. This method worked really well on a Gitane Defi I restored for a friend, those decals were huge, no way you could have just stuck those on, and got it right!

Doug Fattic Given this is a production run of the boom era, I don't expect to find the workmanship you most likely set as a standard! Not the quality of the originals:

Will mineral spirits be a good prep cleaning solution? I also have denatured alcohol. The frame was waxed 6 years ago and not touched since.

Here is a picture of my 2 tools I use to make sure decals go on straight. Just to be clear I usually use them to lay masking tape that will be the guide where to place the decals. I'll often hold the tools in place with masking tape as well so I have 2 hands free to place the masking tape. In addition it can be helpful to mark on my placed masking tape where the center of the tube will be so the decals don't end up off center.

tkamd73 - Very helpful. I will definitely use wetting in the process. Instructions state 3 drops of dish soap to 1 pint of water.

Doug Fattic Very close to the way I envisioned the "fixturing!" I assume the tape at the bottom only serves to hold the angle in place.

Yes the tape in the picture is only used to hold the locating tools in place (in fact just randomly placed to get a quick picture for this subject thread). When I am placing the real locating tape, I don't use regular masking tape like in the picture but rather 3M "Fine Line" tape. It is thinner and has a cleaner edge and when pressed against can leave a mark to show the center of the tube.

I tape a string to the frame to mark the centerline. I pencil another centerline on the decals and line them up under the string.

Sometimes, the decals themselves aren't centered perfectly or they feature more material than necessary, so I cut them with a razor and ruler as an initial step.

That should work, especially for water slide decals, I’d use detergent over soap. For vinyl decals I’ve used VeloCals application fluid, which definitely as some alcohol in it, or 3Ms recipe which is:
4 drops of liquid dishwashing detergent, (not soap) in a pint (1/2 liter) solution of 25% isopropyl alcohol, and 75% distilled water.
Good luck, have fun

I find it much easier to do a dry run to set things up whether waterslide or adhesive and often use my "good" eye as a guide..don't overthink it....what do they say? "measure twice cut once"

I've also found times when thin cloth measuring tape is easier to use (when measuring distances for decal placement) than either roll up metal tape or a stiff ruler. I'll add that my angle piece can also be used to find and mark the front center of the seat tube as well as the top of the down tube for decal placement using the point of the lugs and water bottle bosses. For example the bottom of the seat lug and the point of a bottom bracket shell (if it has a point) can be where one end of the angle iron is placed and the other end used to make a pencil mark where it comes in contact with your placed masking tape. Of course you have to do this on both sides in case the points are off a bit.

Mineral Spirits works well to remove any grease or wax. Denatured alcohol then works well to remove all traces of the mineral spirits.
I just posted this photo in another thread, showing how I use masking tape to box in where the decal will go.

I’ve been following the decal and clear coat threads closely since that’s where I’m at with two of my projects. Today I applied the decals to my 1974 Raleigh International, and it was a nerve-wracking couple of hours. My original goal was to get the bike looking good from the 10-foot range, but the more I got into it, I became more exacting. One problem I faced was that the decal placement seems to be all over the place - there’s no real precise set of locations for some of the decals. I followed the Velocals instructions, and they worked well enough. The process wasn’t too difficult, and the mistakes I made probably wouldn’t be noticed by most riders. For instance, the Carlton decal isn’t centered between the gold bands on the seat tube, and one of the Raleigh decals on the downtube could have been positioned a little differently. Pretty minor stuff, though. My advice is to go slowly, cut the decals with a straight edge, get your tape and marks exactly where you want them, and forge ahead. Now for the clear coat.

My tip for down tube name placement on classic era frames is that it is usually located between the top water bottle boss and shift lever or derailleur cable stop (unless it is a very long name). Otherwise when you are looking at it from the drive side the lettering looks too close to the big chainring. Also there is a tendency for people that haven't thought about decal placement to put the name on the very side of the frame. However one looks down on an assembled bicycle so the decals need to be rotated up so one can read the whole name without kneeing down. This means that the space between the tops of the letters is fairly close together and there is a lot of space underneath the frame between the bottom of the letters. How rotated depends on the size of the letters but 3/8ths of an inch is a rough approximation. That distance varies deeding on the style of font used and whether it has upper and/or lower case letters.

This rotation also applies for any letting on the top tube too. Another rough rule of thumb is that the bottom of the letters are usually right on the side middle of the tube (unless they are fairly better letters). It is easy to find the very side of a tube using tape that when pressed against leaves a mark. I cut a piece of semi translucent tape and place it crosswise on the top tube near the head tube. I take a metal straight edge (usually a ruler) and make sure the edges are touching both the top and down tube at the same time. When I run the ruler over the tape it will leave a mark right on the side. I then place my aluminum angle along the tube tube using my newly created mark as a rotation guide. The angle piece serves as a guide to place masking tape along the tube in a perfectly straight line. The masking tape of course is the guide for placing the decals.

Lucky for me, I was straightening up in the basement today and found: a length of 3/4" aluminum angle!

While it is possible to use frame tubing (of course as a framebuilding teacher I have hundreds of short pieces of scraps), they are a bit of a sloppy fit. The very best option is to use steel tubing that has a wall thickness of 0.058". The outside diameter (ø) will be 1/8" larger than the tube you are placing this tool on top of. For example if you are using the tool on a 1 1/8" down tube, the tool itself would have an OD of 1 3/8" with a wall thickness of 0.058". This is commonly available tubing from steel tubing suppliers. For example Wicks Aircraft or Airport Spruce are 2 examples of places that sell 4130 tubing in those wall thickness. They sell it by the foot (or more).

The purpose of 0.058" wall tubing is because they are a slip fit that can create telescoping tubing with just the right amount of clearance so the smaller tube can fit and move inside a bigger one. I don't know anything about and have never tried to use plastic tubing. It will work if a split piece fits snuggly on top of a tube. Of course I have all the right tools fo make tool #2. I have wood blocks to hold the tubing while it is cut. I have a lathe and/or a belt sander to square the ends of the tubing stub before I split it lengthwise in half.

I did not even know they made masking tape only 1/8" wide. Thank you, Amazon!

(A) This idea of using water on the surface even with a self-adhesive “decal”, is this relatively universal, beyond Cyclomondo, Velocals, etc? I have one set sent by the Palo Alto bicycle shop in CA, peel-n-stick, for all I know the decals are 40 years old like the P.A. frame. I’d like to think those would not need a different application process.

(B) Wow, wondering if I should be thinking about a Plan B. Making up a jig makes sense when doing multiple bikes (five for me), I think I’m reading that I need tools to make tools. I just hit that aviation website, the steel is not all that expensive. But, despite having so many packages arriving for these projects I probably should have a conveyor belt installed at the front door, not sure I can justify to my wife a lathe and a metal cutting bandsaw (bummer, I wouldn’t mind having both)!

Wish me luck finding alcohol during the Covid crisis! I have maybe two teaspoons left; just used about half on a frame post-mineral-spirits. Now reduced to trying to only touching the frame at the shifter bossed and chrome stays.

...sending me right back to square one. DT decal including clear surround is 10-1/8" long by 1-3/8" high. DT lug-to-lug is 22-1/2" long so I figured 6-3/16 at each end beyond the decal -- smack into the bottle bosses. centering between bottle bosses and shifter bosses means only 3-1/2" from the lug (measured from most-scooped-out point). Too far "up"?

I thought about moving it down into the water boss area but--

DT diameter is 1.1305" so circumference is about 3-9/16". Two decals at 1-3/8" high means only about 3/8" open space between decals at the top, and again at the bottom. It's gonna be fun measuring that accurately as it is. But if I slide down into the bottle boss area, the boss measures 27/64", I'm right on an "interference fit". and, anyway, the decal will be visually "obscured" more the closer to a water bottle it gets.

Inclined to mount the decals in the higher position.

I think I need a drink!
