What causes cracking of Premier wrap?

Loading...

My understanding is that , apart from some unique and inventive wraps from Italy, all real drum wrap comes from Delmar. I don't think there is a European maker anymore.This is not to include the stick on stuff and the iridescent or sheen wraps or the thin brittle stuff that comes on oriental products.That wrap is totally different. The difference between sparkle and glass glitter is this. The particles in the sparkle are more or less round and uniform in size and most are laying flat so theu reflect light up through the glossy coloured resin surface.If you look straight at the sparkle, you get maximum reflectivity off the particles, so it has a sheen. If you look at it from a 60 degree angle , you get almost none.In betrween that as you look at a drum , there would be a border between the sheen and no sheen. Sparkle wrap mics at a little over 1/2MM.

Glass glitter, which mics about twice as thick, has enough depth in the resin, for the angular, unevenly sized particles( i think they are aluminum) , to be embedded at various angles, so you get only about 50% reflectivity ,straight on and a twinkling effect as you move off axis. This wrap tends to sparkle more than sparkle but has less direct luminescence and although the pigment seems to be the same it comes off as having a slightly darker colour darker colour on axis and brighter off axis.

The turquoise wrap is a nice colour but is dramatically different than the older wraps known as aquamarine, for which there is no modern replacement. Since you are in the midwest, any U.S. supplier would be about equal for shipping. Precision Drum co., Jammin Sam's or drummaker.com should have it. I've dealt with all and they are all good. Each has some finishes that the others don't.

Well, I'm quite sure that in fact JamminSam and Drummaker both take Delmar for selling and work. As for the europeans, I think that oldest Macuzzelli don't make drum wrap now, but maybe it's not true.

When I've studied situation with materials during preparation to my wrap project, I came to the conclusion that ingredients particles there are very different kinds - alu and mica, coated glass, pvc and others. But most brilliant and reflective of them is 'real sil glass' particles - different sizes and shapes.

Then about cracking, agree with Ralf --- I've met these facts when set was often transfered from warm to cold and vice versa.

Cheers,

George.

Thanks for all the input folks.

Here some pictures of the marine Pearl bass drum I received yesterday.

The wrap itself is thin, very yellowed and became brittle by aging.

The glue seem to have lost all strength. Just by removing the hardware, the wrap jumps up and lets loose. In picture 1&5 you notice that glue was only applied on the sides.

Besides 2 major cracks from side to side, the wrap is showing a lot of small cracks, to be seen in picture2.

Except for the wrap, the drum is in good condition and all hardware is present.

In all I'm happy with my 40.00 investment.

I did a Slingerland snare re-wrap in Turquoise glitter, I just love that color.

For this Premier project, I got inspired by Jon Peterson's fabulous restoration.

Congratulations Jon, what a beauty !!!!

Once I receive more parts, I will start a thread on the progress in the restoration section.

Correct Jon,

My Turquoise Glass Glitter Delmar came from ST Drums in Germany.

Great service and good people to do business with, highly recommended.

Hi there - I can't shed any real light on these topics, but here's a few pix to illustrate. (1) a 1960's Premier Ace in WMP - with cracked wrap as discussed. The wrap is paper-thin as you can see. This is still very much a killer snare drum when put to work. I'm not going to restore it - I think it tells it's own story. This drum was in fact being thrown out by a neighbour a few years back - I did ring their doorbell to check just in case! ...and to follow on from Jon Petersen's post (and excellent pic!) (2) a Premier HiFi in Green Sparkle (Aquamarine?) wrap. You can see that the wrap is now spotted (due to damp I imagine), which is the condition the snare was in when I got it over 20 years ago - but hey - what a killer wrap! Again, I've left this as-is and I can tell you it's also a belter of a snare drum - very loud with lots of character and crispiness - and of course, a real head-turner when she comes out to play...

Thanks for posting Showboy, beautiful drums !

I'm a fan of the Royal Ace too and not only for the looks,... it sounds truly amazing indeed. Not altering a drum wrap is also my first choice but in some cases you don't have another option I guess.

Speaking about the Aquamarine, I agree with you that it's one of the most beautiful finishes out there. As a matter of fact, there is a full kit for sale on Ebay.uk for weeks now and nobody seems to buy them. If only I lived in the UK, I would be all over that kit.

From my understanding, the "Duroplastic" had this problem. I could be wrong, and often am, but that seems to be what some of true Premier pros seem to allude to. If it is not Duro, then I am, again, wrong! Welcome!
