@calfskin: the little screw with "countersunk raised head" or "oval head" comes from the two similar strainer/butt end parts with control knob for the lower snares and canals where the individually snare wires are gliding on (4 screws in total).

The brass screw with cheese head is used to connect the two rods inside the drum with the mechanim mounted at the inside of the shell (4 screws in total).

I use the term T-rods for tension screws looking like a T and were used mostly on bass drums untill in the square headed key bolt took over in the beginning of the 90's at most drum manufacturers.

@capt.wierd: I do have all of the lugs and they are in good hape for their age. They are the art deco style lugs, not the X-box lugs that were used earlier.

well. i havn't found any derelicts.----the lugs I need are the long ones, with the elongated elipse on the top that goes from end to end. they were used in 1937 for sure. do you have a couple? -----regarding the screws. BA stuff is very odd and doesn't conform to the sizes of the screws on these drums at all. BA screws were metric in diameter but only the 6mm was a round figure. others were 5.3,4.7,4.1,3.6,3.2,2.8,2.5. If you convert the 5/32" that I mic'ed those screws at, to mm, you come out with around 3.97----not a BA size at all , not to mention that a 32 t.p.i. thread guage dropped right into it and BA threads were all odd decimal t.p.i.'s-----the closest to 32 was 31.35 and that was for a 4.7mm screw, considerably bigger than the one on the drum.

I guess I always figured T was for tension rod. Since as you say a lot of drums (certainly, Boosey&Hawkes always used a key,until they did the Rogers bowtie thing) don't have handles on the bass drums , it doesn't make sense. I know that it is a common idea in Britain ,though.

Any pix of the said drum?

@JRichard: I do have a lot of pics but I can't upload them here because they are too many bites. I even had trouble to upload the 2 small pics of the screws.

If you send me your e-mail address, I can send them to you. You can leave your address at my private box if you want.

BAs were used on the snare mechanism of the Royal Ace snares

back at Wierd Towers tomorrow and I'll check on the Dominion lugs

Short of another Premier collector immediately providing you parts, your best source of Whitworth and British Standard threaded screws and nuts will be any mechanic whose specialty is servicing and restoring vintage British motorcycles such as Norton or Triumph. They will have all the necessary tools and parts for repairing British drums made prior to late 1970's. In addition, a search for British Motorcycle Tools/Parts on such websites as eBay will likely turn up at least one source for Whitworth tap and die sets, along with Whitworth thread gauge tools. While somewhat expensive, a good Whitworth tap and die set consisting just of the sizes used for British vintage drums is an invaluable thing to own for someone who owns and plays vintage British drums. And simply purchasing a modestly priced Whitworth/Metric thread gauge pocket tool will enable you to know the exact thread gauge and diameter measurements of each and every part you need, which will itself save you lots of time and expense in your search. I have at times had to use my taps and dies to "hand manufacture" the actual correct thread gauge replacement parts for my older Premier equipment, and with excellent results. In my experience most of the vintage Premier line was manufactured using Whitworth, British Standard, and metric thread sizes - all combined into each and every drumset. I have been told that many vintage German companies also utilized Whitworth threading in their manufacturing processes. Best of luck in your search!

I don't think there was very much use of English threads in German drums. I've got over 100 of them from 8 factories and 1 assembler and all I see is metric and standard machine threads(UNC and UNF ----unified coarse and unified fine). I cannot see the point in the Germans adopting such odd threads for drum mfg. when everything else was not .

Anybody need lugs?

Let me know
