These are parts to the bellows

Hi Jay. Been dying to build one of these for a while but decided to wait for topsy 3 plans to build the "ultimate" machine. Having just received my plans I have just skimmed over them but it appears a good bit of head scratching will be involved. Your photos are going to be a big help with that. Hope others will build also. Quick question: where to get the special bellows leather he specifies at a decent price and haven't quite figured out how many pallet magnets are needed to build the full blown with percussion totally awsome when finished ultimate music machine. Thanks for your help.

Ted the Leather you will be able to get from A Turn N Time as soon as the dummy gets the site up and working (ME)
I am close to covering mine and have been waiting to see how much it takes so I wont shoot my self in the foot by under pricing it.
I bought a box of 90 ohm pallet magnets from Paterson (64) I know it takes that many for sure and maybe a few more. Cost is the same on them if you buy 1 or 10,000 so ordering more at once dose not save you anything.

I am going to build the full blown Topsy also and will post here as I build. I have some great contacts to help us all work thu problems with the MIDI system and I am planing on getting supplies from the USA for them also and possibly work up some ready made circuit boards to have available.

I also have contact with John when needed too.

Oh and Welcome to the FWW Ted Please put where you are located so we know how to razz ya

Jay,

How many and of what sizes of pallet magnets did you end up using in total?

Are you happy with the Paterson pallet magnets?

I used 8 from OSI but will not do that again the shipping from them was nuts. I like the Peterson much better. I have used 80 between the main windchest and the acc windchest 72, 90 ohm 5/8 pads and 8, 60 ohm with 3/4 pads for the bass. I also have bought one of the 60 ohm valves with the longer arm and no pad for the Triangle. I am still trying to find a good solenoid valve for the woodblock and will post what I find as soon as I come up with something.

So count so far is 81 valves.

I would also buy there installation tool next time. I got it done but that tool would have made life alot easier.

A lot of time could also be saved with there mounting strips too.

Wow, that is a big bunch of valves in such a small space !

Did you wish you had the frame adjusting or pipe valve locating tool?

I'm also assuming you went with the front tabs and not the side tabs for the spring.

Can't wait to see your next progress report.

Thanks for sharing.

Oh.... I got an email today from John's daughter and it had a link to your website of Topsy parts. Just Terrific!

I used push solenoids mounted from below for the wood block from all electronics part number sol-102 12 volt miniature push sol., they work well.

Jay,
How did you come to use the 90 ohm instead of 60 ohm units?
I would think the 60 ohm would be a bit more powerful.
It is a function of the capabilities of the register board?

Jay,

I'm REALLY glad you're many steps ahead of me. Those photos are very helpful.

Question: The plans say to mark the positions of the airholes. I would love to mark the positions of the airholes.

What exactly ARE the positions of the airholes?

I know there are 13 of 'em. I know they're 3/8" in dia. I know they run down the center of three of the four bellows boards.

And they look lovely in your photo by the way.

But can you give me a hint how far away from which end of the bellows boards they should be? Does it matter? I know John said that exact measurements would only be given where needed.

(I'm almost dead certain this question is going to wind up making me look stupid, but I got over that a while ago.)

[Jay Caughron]

I made it back late last night Brian. Sorry I wasnt able to check the forum while on the road (1700 miles in less than 3 days thats with one day of rest) Today I have been in a daze and glassy eyed


I made the holes 5/8 center to center the strip of leather called out for is 10" long and this space seem to work out just fine for me.

On "A" and "B" I marked the first hole centered in the boards and marked 6 each way. On "C" I marked one hole centered and marked one to the right and the rest to the left of center.

Don't forget to use some sealer where you are going to drill (both sides) to help avoid any tear out you need the side the flap valve is one to be perfectly flat no tear-out.

If you still need help I will be here the rest of the night and will be checking emails as Im to tired to do anything else
