**I bought some items from momeraths24 and they are great pieces. Everything is very nicely made and I am pleased with all the parts…But there is something that has been bothering me. The PPD momerath24 made seems a little big to me. I once bought a PPD from MMM and I remember it being thinner then this PPD.
Now I don’t know if it’s just me so this is why I’m asking for your opinion. I don’t want to bother momerath24 about it unless there is actually something to correct, so HELP ME OUT and let me know what you think. Am I wrong and is it actually the correct size and is there anything else that may be making it seem larger to me than the previous PPD I had??
Well here are the pictures of it:

**Best Reference shot I could find to compare to my picture:
Yes it does look a little oversized to me. Going by the screen used pack in the photo the PPD seems to be the same diameter as the filler tubes next to it. Measuring mine on my pack (which looks right to me) the diameter is 1 1/4".
The PDD I made for you is based on Stephan’s plans found here on GB Fans. I’m not sure how accurate these plans may be; however, they are considered to the most accurate plans according to GB fans.
Here’s a picture of a mock PDD I use as template when I fabricate the main body to get the correct width.
I always say that every shell is going to have something different and it seems that Mike’s shell is made to use a smaller PDD. Possibly a 1 ¼ VS 1 5/8. The tube on the left is 1 1/4 and the other one is 1 5/8.
If you haven’t installed the PDD or made any modifications to it, please send it back ASAP. I’ll be making more this weekend for another client that is using the same shell I can possibly make one for you as well. I’ll save this info into my files so when people order these parts I can modify them base on their shell.
Yes, Stefan’s plans say the piece is 1.375" OD, so momeraths24’s PPD is accurate to that. BUT from the scaling that I’ve been doing with some friends to update stefan’s plans, the PPD, along with the beamline and filler tube seem like they are more likely 1.25" OD. It still looks good though, he does nice work, its just too big
i will say stefan’s plans arent as accurate as most people think because alot of his measurements and how he made things looks like he was just learning it.
hell, putting it all in engineering measurements was the first dumbest thing he did because you have to convert everything to understandable measurements.
**I agree his work is GREAT and I’m not trying to discredited it I just felt that this piece was a little off and I didn’t want to bother him with my concern without having the input of much knowledgeable members who know more about the plans and measurements than I do. Thanks for all the info and Franchesky I haven’t done anything to this piece yet b/c of my concern of it being a little off so I’ll be shipping it back.
I could be wrong in stating this, but I don’t think that part sizes will vary based on which shell you’re using. It looks like a PPD should be 1.25" and that will stay the same whether or not you’re using a fiber glass shell by maker “X”, or scratch building your own. This may be worth looking in to as it would save you a lot of time and frustration.
Really depends on which pack you scale from. Going off the PH pack the discs scale out smaller than the fillers. (I will try and work on a fancy comparison when I have more time) I have not taken as much time to scale out some of the other packs due to the quality of the pics themselves but I will note there are things that vary from pack to pack.
For the record, I too get 1.25" for the fillers based off the PH pack.
OK, your new PPD is completed using 1 1/4 OD tubing for the main body, and I used a new method to fabricate it which works faster and it looks 10 times better.
I’ll post pictures tomorrow and I’ll be updating the description on this item on the “for sale” section.
I get so tired of people relying on measurements down to the nanometer. Trust your eyes, trust your guts. A wise man once said " trust your feelings." If it feels wrong, then it IS wrong.
