Bass Leadpipe

Post by walldaja »

I looked for replacement pipes on line and only found 0.562 diameter pipes. Do folks use 0.562's in 0.563 bores because the difference is so small?

Thanks
Dave

The difference is nominal. Yamaha cites its specs as 14.3mm, which is the mm equivalent of .562 to one decimal place. But when you convert that back to inches, with 3 decimal places, you get .563. Leadpipes are actually at least .005 inch smaller than the bore size anyway.

To echo Brad. A pipe that measures an OD of .562" would be near impossible to get into the tube. This applies to every size of slide. The leadpipe has to be several thou smaller than the ID of the tube.
