Happy holidays, dear Colin! I hope the money has been received. You didn't answer about the glue.
Sincerely, Vladimir Meglinsky
I bored the holes all the way through the hub and used a 'ramin' hardwood dowel rod to fill them. Apparently its properties are similar to beech.
I intend on replacing this propeller before the airplane is flown, but I need to mount this propeller so that I can perform taxi testing and break in my rebuilt engine this winter. This propeller will be removed and displayed on my wall, but I need it to provide a load and cooling airflow until then. I cannot afford to wait six months to have another prop built before I resume work on this airplane. I understand the cost delta between functional and souvenir propellers, but I did not set out to purchase a decorative/souvenir propeller. At this point, I'd be satisfied with a $400 refund and keeping all this between you and I.
Thanks,
Colin
Dear Colin, I thought you were going to keep it as a souvenir. Although the propeller was not installed on the airplane, its hole system had to be redesigned. Epoxy was used to glue the boards together. Any holes made and material removed should be done in a dry area and immediately sealed with varnish or resin to prevent water vapor from entering the wood. The work you have done is a matter of absolute respect. Thanks so much for the photos, especially the dimensional diagram. But in any case, our costs in its design and manufacture are disproportionately higher. I think you'll agree with that. The proposed 50% was implied when using the propeller as a souvenir. Our souvenir propeller of similar size with no fiberglass fabric and no steel protection costs about the 50% quoted. One customer in the USA is waiting for a decorative propeller from us, another customer I would love to give it to.
When the propeller is used for its intended purpose, the proportion is quite different. We have no more than 5% of the total labor cost to make the holes. Believe me, our costs for this propeller were substantial, and I want to at least partially compensate for them. On the other hand, I would like to minimize your negative impression of our mistake. So let's look for another ratio.
Dear Colin, I happened to notice one important circumstance. In this connection I have a question: Are your plugs through and through, all the way through the hub? What kind of wood are they made of?
Sincerely, Vladimir Meglinsky
Vladimir:
It seems like the bolt pattern was located about .030 off axis, just enough that I could not get it to fit the crankshaft flange. Moreover, the bores of the drive bushings were contaminated with some resin-like material, and when I attempted to remove the obstruction, I discovered that the bolt pattern had been plugged and redrilled three times - I was under the impression I was buying a new propeller, not a reworked one. I bored each of the six holes up to 1.25 inches and inserted a hardwood dowel, then redrilled for a 3/8 bolt and reamed them for a 5/8 drive bushing concentric to the center bore. It fits my crankshaft now, but I haven't reapplied any varnish or topcoats, and I have not yet repaired the damage caused by its excursion from the packaging tube. Is the wooden core sealed inside a typical fiberglass resin and cloth layup, or how would you advise I finish the hub in a way that's compatible with your materials?
I'm going to need a larger refund than the proposed half minus the cost of shipping ((855/2)-150 = 277.50 USD) This is a considerable amount of unforeseen labor on my part, and frankly a disappointment after waiting this long for a propeller you said was ready to ship in mid-July.
Thanks,
Colin
I'll get it fixtured in my mill soon and try to derive some dimensions from it.
Thanks,
Colin
You're right, of course. Although the classic wooden propeller is a very robust unit. It is glued from many boards, and the destruction of any of them is not critical. Additional reinforcement is the fiberglass cloth on the outside. Any propeller designer is primarily interested in the achieved efficiency of the propeller at least on the ground. Although ground performance is only a proxy for flight performance. I have aviators in the US who ask for a decorative propeller. There are also people in the US that I would like to give a gift to. But if you would like to keep it for yourself - I would be happy to do that as well. And of course I will send to Paypal half of the cost of the propeller minus postage. Nevertheless, dear Colin, it is very important for me to know the degree of axle misalignment, and I will be glad to take measurements. At least the dimensions between the walls of the bolt holes and the center hole. I need to get to the root cause. USPS-- that's what the translator said.

Vladimir:
It was UPS, not USPS, who shipped the prop from the Meest office in New Jersey. The tape on the ends of the tube did not look like it had been cut; rather, it looked like it tore along the hard edge of the tube as it shifted or rolled in transit. I can only speculate. When I received the propeller, UPS had relocated it to an unclaimed goods warehouse in Salt Lake City, Utah, and then repackaged it in a new cardboard box and wrapped it securely in brown paper and foam. It has no visible cracking, but there are some small nicks and gouges in the trailing edge and scratches in the paint. It could probably be 'dressed' and repainted after inspecting for damage, but the offset bolt pattern remains a problem for me. I'm a metal fabricator, not a woodworker. I have a good milling machine with a rotary head and I could probably rework the bolt pattern, but I have lost confidence in the propeller. I don't know what mistreatment it may have endured without its packaging, whether someone stepped on it or bent it and inflicted damage to the wood fibers that I can't visually inspect. It's not worth risking my life as a pilot.
It's a good looking propeller and I'd be happy to display it on my wall, but I would like to receive at least a partial refund as I can't consider it airworthy.
Thank you,
Colin
Hello, dear Colin!
What did the post office say? How did they explain the opened parcel and the damage? Was the propeller wrapped in foil? Were there protective covers on the ends of the blades? Are the tips intact? Are there no nicks or cracks?
We're trying to figure out where and how much error was made. I have just now checked again that the bolt holes were drilled using a steel conductor. The conductor in turn was centered using a steel bushing turned on a lathe. All the centers should match. Could you measure the amount of misalignment or roughly estimate it? If the misalignment is small, you can carefully re-drill (increase the diameter) the bushing holes, allowing the center pin to enter. Once the center pin is in, this will ensure the propeller is properly seated and balanced. The enlarged holes need to be varnished. If the offset is too large, you will need to glue in wooden plugs and re-drill the holes. This sounds simple, but actually requires special equipment. We can do it of course, but the shipping costs have become too high, three times the cost of the propeller. It is probably easier for you to buy a propeller somewhere nearby. I will have to apologize to you and refund your money.
Sincerely, Vladimir Meglinsky
UPS found the propeller and returned it to me today with only a few minor scrapes and chips in the paint.
I tried to mount the propeller and the bolt pattern is not drilled concentric to the center bore. I cannot use this.

Dear Colin, I called Meest Express just in case and outlined the nature of the problem. I was told that you should contact their New Jersey office at 18002889949, 17326341517. Presumably you have already reported the loss to them?
Sincerely, Vladimir Meglinsky
The mailing tube arrived via UPS, but the tape had failed on one end (and nearly on the other) and the propeller was missing. I have filed a claim with UPS and I'm hoping they can locate the propeller, but I'm not sure if it was separated from the package when it was in their possession or with Meest.
Please see the attached photos.
Regards,
Colin
That's great!
Sincerely, Vladimir Meglinsky
Yes sir, I got that confirmation as well. I made arrangements for Meest to ship it to me via UPS. Looking forward to receiving it soon, and then I'll reimburse you for the shipping cost.
Thanks,
Colin
