Re: double-throw bellows, anyone?

Hey OOTB, stop dumping on everyone's good ideas for a change! Jeez!

I kid, I kid :wink:

Re: Pressure valves

Ofcourse there's the whole school of thought that sees a relation between tone and the diameter of air inlet in (for example) the chanter. That makes sense, since the chanter requires rapid pressure changes to driven properly. But OOTB's constriction idea is to help limit these fluctuations for the...

Re: double-throw bellows, anyone?

I worked on this idea a few years ago, but scrapped it. Just silly complicated, compared to a nice efficient "normal" bellows.

I'll try and dig up my photos.

Re: Pressure valves

just a wee reminder: It´s not the pressure but the airstream. More detail next time, please. And I originally proposed the idea of a constricted inlet on a hollow stock. I merely meant attaching an adjustable valve on the main inlet. I am aware of the benefits of the shared airspace, phase locking ...

Re: Pressure valves

That sounds like an excellent and simple way to experiment, I'll have to try that. I wonder how I can integrate simple setscews into a wood stock. I just bought a bunch of square brass tubing, however. Going to experiment with drone reeds for a while. Probably not going to make an inside-out reed th...

Re: Pressure valves

Sounds very cool. Though I'm not sure it's necessary to work with those industrial valves. I think if you were to take one apart the design is simple enough to duplicate in materials and scales more easily integrated into our mainstock. Just thinking about footprint, here. Subtlety. I just finished ...

Re: Pressure valves

Alright, that looks like the slot headed part is a cylinder interrupting the bore with a hole through it's side. Rotating the cylinder shifts the hole out of alignment with the bore, causing an adjustable constriction. I'm fairly sure this is the design Whitmer uses in his simple petcocks, although ...

Re: Pressure valves

Interesting to ponder the constrictions already present in a set of pipes: the inlet tube of the chanter, the small holes that feed each drone in a (more common modern design) mainstock, and even the regulators sometimes have constricted inlets. I think you're onto something here. Control is the nam...

Re: Pressure valves

Those of a nervous or conservative disposition may wish to look away now. For some reason I didn't. Not all of your ideas are crazy! Though In this case, the Highland piping community has beaten you, they've had this for a decade or more for their drones, primarily to prevent after-squeal when stop...

Re: Composite Drone reeds (renamed)

I think it would be safe to winnow out some ideas that on the face of them violate the laws of physics. Spot on. And innovation purely for innovation's sake is rarely merit worthy. The classic makers had reasons to improve the instrument. Correct me if I'm wrong, but double chanters were on the evo...

Re: Composite Drone reeds (renamed)

A few of the older UP sets actually did have regs like that, with an individual reed and chamber for each keyed note. Just goes to show that there was, indeed, experimentation going on all the time, even back in the sacrosanct "Golden Era". djm Got any photos/proof of such an instrument? Sounds fas...

Re: Composite Drone reeds (renamed)

If it makes you feel any better, I have received similar flak over wondering if cylindrical (non-tapered) bores could be made to work in regulators (imagine three bastardized scottish smallpipe chanters) instead of the traditional design. However, I wouldn't post anything on this forum about it with...

Re: Composite Drone reeds (renamed)

Well, I deserved that response. This isn't the place for us to blow off steam. I praise your level headedness, sir. This is certainly the best uilleann-centric forum out there. (A point of clarification: OOTB didn't suggest free reeds, he merely alluded to a harmonica possibly not knowing that it us...

Re: Machine stitching leather bags

Michael Mac Harg used to hand stitch by this method... For anyone who doesn't know, Michael had to drop this method due to health reasons, the process was extremely hard on his body. Considering the volume he was producing, I am not surprised. L&M uses prison labor to stitch their bags. That is a s...
