I have wrap fixture (I wont mention who) that I have not been all that happy with. Wanted to try something new - before I try would like to get some input.
Why couldnt someone sand the wrap grove down to the leathers thickness and using a piece of irish linen determine the "length" of the top and bottom of the wrap (circumferences). Then measure the length of the needed wrap. Using a wrap blank you have all the measurements now - using a ruler draw a straight line down the middle of the wrap blank. At right angles mark the top and bottom of where you plan to cut (length of wrap). Now take your pieces of irish linen - fold in half and mark the length to the right and left at both the top and bottom.
It would appear you could just cut out a perfectly measured wrap and install. I am sure someone has tried this - has it worked?
Hi,
Like any skill set, experience with good results breeds confidence. Making mistakes and implementing corrective actions is the best teacher.
Trust your fixture and you will gain confidence. Do 50 wraps or so and you will learn by all of the little adjustments you have to make. Here are a few things that hung me up for awhile and might help you:
1. Use a flat edged safety razor, not the utility blade because they have a pronounced beveled edge and will screw up the precision of the 2 straight geometry range lines you have to marry. The safety razor will remain flatter on the cutting bar. This makes a huge difference, at least it did for me. Buy 100 at a time in a box and dedicate yourself to only making one cut per edge. After making 2 cuts with one blade I put them in a used blade box and reuse them for other tasks but I never cut leather twice with the same edge. If you think this is a little anal, just inspect the blade under a microscope before and after cutting one piece of leather.
2. Like Dave pointed out, wraps react and stretch differently so I would not try a Lizard for example until you are completely 100% confident in the 2 seam cuts lining up because some materials won't stretch that much.
3. Learning the final elevation tweak of the step to match the leather thickness takes practice and observation skills. Too high is no good and too low is better but still no good. It has to be perfect. It is a good idea to have lots of wraps around and mic them, then write the size on the back.
I stock about 100 wraps ranging from .019 to .026. It's easier to match a wrap than to do too much adjusting by sand or filing. This is what I call the danger zone, one little false move and you can mar the finish and have to re spray, wet sand and buff again.
4. When you glue the initial section of the wrap while lining up your pencil marks only glue up about a 3/4" section and make sure it is set before cutting the leather. By doing a smaller initial area it gives you a little wiggle room for stretching but does not hurt you if you don't have to stretch that much. After trying different glues, I prefer tight bond with a few spritz of water.
Use and master the use of the fixture. Keep up your efforts with a keen eye and question everything when you don't get the results you want. Before you know it, you will become very confident in the outcome before you even start.
