Bumpers...
I bought an old English Bass early in 2006 in much need of repair. Since it was a supposed Fendt (later discovered to be a Hart Bass) with the sound to match, the repair costs didn't scare me. One thing was that it had Bumpers on both sides, upper and lower Bouts. They were circular Ebony buttons *about 5/8" in diameter (*Arnold might have some left to measure).
My plan was to maybe put them only on one side when the Bass was done but when the Top, Back and Rib assembly were all apart and the restoration underway we noticed that the Bumpers were 'dowel' pinned somehow into the Ribs. This Bass had its Ribs completely doubled so this was not visible until the doubling was removed from the inside. Now, I had 8 holes in the Ribs that had to be filled. The new plan was to make 8 new Bumpers and cover all the repaired holes. Heres some 'before and after' pics; Sorry about the hard to see b4 pics. Here's the 'after' shots showing the new Bumpers along with the Gilkes; The other day I was on an Orchestra gig and my buddy using my Gilkes mentions that I laid the Hart Bass down on the wrong side when he noticed the Bumpers on the 'up side'. I proudly said "it has Bumpers on both sides". The Gilkes he was using only had them on one side. My Loveri is now in restoration and nearing its completion. I just called Jeff Bollbach and told him I want Bumpers on the Bass when it's done. With the Loveri the Bumpers are very necessary since the Ribs are nearly flush with the Top and Back. The Back was just widened to overlap the Ribs a bit but the Top is still mostly flush. The Bumpers will help keep the edges from further damage. I will post the b4 and after of the Loveri when it's complete as well. |

Ken,
I recall the great bumper debate on TB a while back. What did you have Jeff or Arnold use for bumper material? BTW the after photos look great. |

materials..
Quote:
The Gilkes had quite a bit of edge work done on the Bass so Arnold and I discussed the Bumpers and he made them in a Maple to somewhat match the Ribs. The Hart Bass has Ebony bumpers all around. On the Loveri with Jeff, we just discussed it today during an update on the progress of the restoration. I will let Jeff use what he thinks is best. Maple, Ebony or maybe even Walnut like he used for the Back center strip to expand the width. I gave him a board of Peruvian Walnut that I have had in stock since 1993. Walnut is very stable as compared to Maple to begin with and sitting for 14 years makes it that much better I guess. |

Hey guys-
Years ago in previous employ we used to scrape off the varnish, score the rib with a checkerboard pattern, and crazy glue the leather bumpers on. Always seemed pretty nasty to me. The problem is that a material like wood or leather will not glue on to a varnished surface well. What I have found to work well is thick neoprene glued on with contact cement. It does not harm the varnish and if they come loose the player can reattach them by themselves without visiting a luthier. |

Jeff's neoprene bass bumpers
Quote:
The neoprene looks like ebony and provides the bass w/ a bit of cushion when placed down on a hard bare surface. I'm less than 5' 7" tall and play w/ the end pin out only about 2 inches, so when I place this bass down w/ its fairly large lower bouts it rolls along that bout edge a bit. For this reason we decided to place four pairs of bumpers on the G side. One pair on the upper bout and three pair spread along the lower bout. Now I can roll the bass down along the lower bout w/ a pleasant cushiony feel knowing that my edges are being fully protected. In almost 5 months of heavy use none of them have come off yet, knock on wood . Jeff shapes them by hand very nicely so they look good as well. I'll post pix of them when I get a chance. THANKS Jeff! Ken, I too had read those bumper TB threads in the past and had agreed w/ you about only wanting to use hard wood or maybe leather in a pinch, but I have to admit that Jeff's neoprene really has worked out well and they can always be easily removed w/o any damage. No more schlepping a bass stand (unless I'm doubling on BG on a crowded stage) or a rubber mat to gigs. You may want to consider them for the Loveri, which I saw, BTW, with the top off in Jeff's shop. A beautiful bass. Happy Winter Solstice Holiday Thing, Bri __________________ |

well..
On the Loveri, you saw the Back off, not the top. The Top/Ribs/Neck are still attached. It is the Back that is getting all the much needed work. The Back made with some crotch or butt end knotted wood that looks like a Cat's Eye figure wise..
On the Neoprene, Jeff used that same stuff for the under side of the 'fingers' on my Bisiach Extension. It works great by the way and I look forward to getting my Loveri back sometime next month with some new Neoprene Bumpers on it. I think I'll request them on the Storioni as well. As far as how much I lay the Bass down, it's not much. I usually lean the Bass C-bout on a chair. When I first saw the Philly Orch., it looked like they had Stools with a side chair for the Bass. I looked high and low for this product and came up empty. Then one day after meeting Hal Robinson I emailed him asking about it and he told me the just place a chair next to each stool as a tradition they have there. Well, I've been doing the chair thing all my life so I've stuck with it. On occasion, there is no chair around to lean the Bass on and I have to lay it down. That's when I need the Bumpers. |

Merry Christmas to all.
Paul Warburton uses old pieces of fan belts, and glues then on with rubber cement...works like a charm. Here's my patentable, removable bumper that I will divulge in the sake of preservation. When you have top or back off, glue on one of these inside the bass at the points where you want to stick the bumbers. Line the bumper underside with felt so the finish will be unharmed. http://www.pennstateind.com/store/emag34.html |

Very interesting concept with the magnets.
I first tried rubber cement with the V belt, but they didn't stay on. Maybe I just don't have the touch. Hide glue works well. |

Best ones I could take. These pics are under the intense flash of my camera. In regular light they look like ebony.
BTW-Anselm, did you by any chance play in a youth symphony in Bremen under Herbert Kolovski back in 1989? |

I've recently been on a weeks course with the English player, Danny Thompson.
His fine old full size French Bass, is attributed to Gand C1865 and Danny had Ebony inlaid into the the actual edges of the upper and lower bouts several years ago. No doubt a tricky job, but it works very well. Has anyone else come across that solution?

Inlaid?
Quote:
All of this work was removed during the recent restoration and the Bumper holes filled. Ribs were re-repaired and Lining was installed inside the Bass as it should be. Here is a picture of the old Bumpers what little you can see in this pic; These round Button style inlaid were on both sides, a total of 8 of them on the Bass. Here is what they look like now with the new Ebony fitted (not inlaid) Bumpers. Hey, I just realized that my first and initial post of this Thread has all thee Pics and more. I mentioned they were 'dowel pinned' but maybe 'inlaid' would have been and easier term to understand. I can't see what they should be inlaid unless done to cover up some other damage to the Ribs of the Bass. If you mean inlaying them intro the actual Edges of the Top and Back I think that's strange and easy to break off in time. The Purpose of the Bumpers are to actually 'protect' the outer edges. Why use them as Bumpers? |

Neville Whitehead uses maple half-edging to the purfling line at certain points on new basses Charton's B21 uses a hard rubber insert into the edges. He claims it is easy to replace when it wears out. |

Yes Ken, the Ebony is actually a flush part of the edging now. You can see it in the picture and also evidence that at some point, other bumpers have been on that Bass.
With reference to damage to the original edging; Danny told me his bass (Affectionally named Victoria,) was quite heavily damaged during a customs "inspection" at Heathrow sometime back...so maybe thats when the alteration was made.
