custom miracle mod amazing !!
« on: June 01, 2012, 06:06:26 PM »
hi, i just installed a custom version of the miracle mod, by adding bumps

it feels really light compared to how it was. there is little hammer bounce now. whats more amazing is it took me about an hour. i  highly recomend this mod to anyone with the same action - mine is a '77 with plastic hammers with felt on the bottom, i left the felt on the bottom of the hammers, and put the bump on the edge of the pedalstal, it plays amazing now, it also reduced the key bounce.

next i am going to replace the grommets, and maybe extend the 2nd to top tip range down to middle C!!!!!

Hi - I've been thinking about doing this - you've convinced me!

What was the product you bought? The link below just goes to a search error page.  And what glue did you use? And how did you cut the rod?

Thanks!
Mike.

I use a very conservative amount of medium viscosity super glue to hold the bump in place, then glue the felt down over top. I've used wood glue and, more recently, hot hide glue for the pedestal felt.

The Miracle Mod is definitely a must-have on pianos with flat pedestals. The difference is night and day.

Felt over the bumps helps prevent them from falling off and cuts down on noise a little.

I used the 1/2 round rods from amazon and started on my bump mod, about 1/3 of the keys done.  I used some left over PVC pipe cement on a Mark I, just the bare bump and no felt on top.  Yes, it is a night and day difference!  I'm very happy with the results.

Huh. I wouldn't think would work at all. I thought PVC cement was just a solvent, not an adhesive - that it only worked by melting two plastics together and would do nothing when applied to wood.

I guess if it sticks, it sticks.

I'm looking to do this as a much cheaper alternative for the miracle mod, but how much do you need to order? I can't seem to find any info on how much you get.

Other websites selling the same product indicate that a pack includes 5 sticks, each 250mm (9.8") long.  I'm not near my Rhodes to measure it, but it's possible one pack might be all you need.

Yeah, I thought the same, but I figured what the heck?  It's there.   ;D  I used Weld-On 700 PVC cement.  I don't expect the bumps to stay on forever, but it was great for placement.  I lucked out that my bumps are glued to the edge of the pedestal.  If/when they fall off, I'll probably use Super Glue.

I also ordered one pack and it looks like enough material for my 73; not sure about 88.

I'm not sure there's a correct answer for this. If you follow the Amazon link above, it gives the dimensions of a bump that some of the people here seemed to have success with.  I don't know the dimensions of the Vintage Vibe bumps, which have been used with great reviews for many years.  But several years ago, I wanted to buy a bump mod setup from another well-known vintage keys shop. I was told that every piano is different, and they test several different size bumps (and bump locations) before installing them on pianos.  Since I live hundreds of miles away from that shop, at my urging, they shipped me what they called an "average" size bump. It is considerably smaller than the half-round sticks that Amazon is selling.

(In the end, after carefully making adjustments, and cleaning and lubing the action on my '74, I decided the action was excellent. So I never installed the bump mod. I don't doubt that the mod makes a great improvement in many Rhodes pianos, but not every piano needs it.)   

If I needed a bump mod kit today, I would buy the Vintage Vibe kit. They probably have more experience with this than anyone.  And while you could likely save some money buying from Amazon (and hope you bought the right parts), this is a labor-intensive job you wouldn't want to have to do twice.

Thanks for your reply !

I did not open the amazon link and they say : 125'' Dia � 0.0625'' H � 10'' L.
So there’s a part of the answer.
When the topic was created, it was difficult to not buy the parts but now in 2020, if I could know the average dimensions, it could be easy to 3D print them at different thickness.

And, you’re right, every piano is unique, and maybe mine doesn’t need the mod. When I got it, I dismantle it and began the restoration. So when it’ll be finished I’ll see.
But it’s an early 1973 fender, so I think it will need the mod.

On another side, I’ve got a 1971 Buz Watson with the Marcel curve pedestal, it’s unmodified and he’s perfect. A bit heavier than my 77, but what a pleasure !!!

Thanks

I had a '73 for a while and the action was very heavy. So I don't doubt that yours may be, too.

I have a piano bass with the Marcel curve, and it's great as it is, too.

Thanks Alan !

I’m also searching for different felts used on Rhodes piano.
I need the key pedestal felt thickness, I read on the forum that a .08” is an average good thickness.
I need too the key bushing felt thickness, and I think that this one is thinner.
Could someone help me on that ?

I don’t know where to find this stuff, I live in France and it’s way more difficult than in US.
