How to "Finish Sand" Your GT Block Stem Face After It's Re-Powdered

OK this is just one method... But one of the easiest full proof ways to get decent results not using powertools or anything expensive. Be sure to take your time and it will come out great. If you look at a Factory GT block stem face you will see that it has deep grooves in it. I am pretty sure GT used a Belt sander or Standing Belt sander to do this. And they obviously used a rough grit of sand paper if you look at the face of a original stem. I chose to use 100 grit in this series of photos. It leaves lines although not as deep as an OG stem face. Some people polish the front with finer sandpaper or even buff it to a mirror shine. Personally I think that ruins it and makes it look like the Horrible "Coffemilk E-bay Repro's" The lines from side to side keep it looking alot more original... OK here we go... Remember that this technique can be applied to Haro stems and most any other stem or part with raised lettering like this... Just be sure to mask all areas with tape that you do not want to actually sand...


Here are two faces side by side... One is OG one is newly Powdered...

Take the face and tape the four sides like Pictured below here...
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1146.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1147.jpg

Then tape the other four corners like this... This is a necessary step to protect the powder from getting scratched where you dont want it to... Dont be afraid to use alot of tape here... One Time I almost sanded through a corner ruined it... Looks kinda like a stop sighn now...

Next find yourself a nice Block... I use this one made out of steel... It has a Very hard Flat surface which is perfect for this application. You can use a block of wood or hard plastic I am sure... But using somthing heavy will work out better and will sand with a much more level surface... Take a piece of your sand paper and wrap it around your block as illustrated below...
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1152.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1153.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1154.jpg

Place the face on a Flat surface or in your hand and begin to sand in one direction from side to side (on GT Stems) or what ever direction on another object depending on how it was originally done. I think Haro stems were vertical in their sanding lines... Keep a good grip on the face and begin removing some of the surface powder...
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1155.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1157.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1158.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1159.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1160.jpg

BE PATIENT!!! After you have started to get through the powder start sanding in one direction only. It is good here to use the side of the block and a narrower part of it to get the last deeper parts of the powder removed from the surface. Take your time and be careful... I actually got this done in Less than 15 minutes... But this is my 10th time doing this or so... If you are a rookie go slow and you will get a great result... Here is some more work in progress...
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1161.jpg

And here it is pretty much Finished...
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1162.jpg

Peel off the Masking tape and admire your work... You now have a stem that looks like new... If you want the deep grooves back you can switch to a 60 or 40 grit sand paper and in one direction put some deeper grooves back in the face. But you need to do this after you have removed the powder with finer paper first. Remember you are removing some of the Aluminum surface too so you wont be able to do this too many times without eventually erasing the face all together. Here are some finished pictures... The result is great!!!
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1163.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1165.jpg
http://i261.photobucket.com/albums/ii50/Rividude/GEDC1166.jpg

Some people might be brave enuff to use a belt sander... But one mistake and you will blow through the tape and ruin the part... I say be patient and do it by hand. Its cheaper and it's safer... Especially to the layperson who is doing this for fun... Hope this helps some people out... wink

Keep in mind that not all the circles have the same rise height. I seen some where it would be imposible to sand much off.
