Hatz Biplane Association

Hi all

Concerning those cabane forks, we wrote that our supplier would be interested in a new run if there would be at least 7 or so sets. He would then handle a collective order (single shipping address) on his own with us just as a translation support. The payment would be directly to the manufacturer. We don't want to deal ourselfes with goods others have manufactured!
So, this source is to be considered for the case you cannot find someone else to make it for a reasonable price. The Swiss manufacturer hasn't made the price yet, but we guess it would arount $ 40.- a piece.
An aerospace English S80 stainless steel would be used.

Concerning the square (not streamline) tie rods (drag/antidrag wires), we are still interested to manufacture them! They have been published in another post on this forum. As our machinery is normally set up for making the scale streamline flying wires (with the max size M4, wich has a 4.7mm x 1.1mm section), we would need a total of 5 orders to set-up the machinery. The wires would be less clevis terminals, as they are available commercially. Threads are UNF 10-32 rolled. Material is stainless AISI 316L and strengt is the same as Bruntons round drawn tie rods. The weight saving compared to ordinary round 3/16" rods is about 3 pounds. Cost per set of 24 wires at nominal 24" lenght (pin to pin) would be CHF 640.00 (about $ 665.- ) plus shipping CHF 80.00 (one set). For those interested, please contact us directly :

Here is what weposted on the forums:

Hi everyone,
We think there is no news that we make available our 1/8" light weight tie rods with rolled UNF 10-32 left- and righthand rolled threads. The material used is a AISI 316L stainless steel which meets easily the specs (min. 2100 lbs), what means that they are able to carry the same loads as Bruntons AN 703 round drawn tie rods. A set of 24 pcs. at 40" (AN665 clevis pin to pin) weights almost 3 pounds less that a set comprising of full 3/16" round wire with cut 10-32 threads. We made our own such tie rods for our Vintage Hatz (Classic) and would like to provide this service for others as well.
By coincidence we found an old ad in a 1929 Aero Digest magazine by the then Stewart Hartshorn firm (New York), who manufactured just then what we have released nowadays.... See picture and ad included.
Please ask for a quotation at hans.u@aeroplaneworks.ch. We can make lenghts up to 50" by the way.

If the price is truely the same *including shipping* then I would say the business should probably go to the first offer, or to fellow Hatz builders.
That would be my vote, but I will go with whatever the majority vote is.

I contacted Carl @ Comp Tech-EDM and his price did not include shipping. I can't imagine shipping would be all that much, though.

HI Doug,

Count me in for a set.

Nick

Hi everyone,

My price of $50 ea. would not include shipping. However, I will ship to individuals or to one person to distribute to the group. It depends on what the group would like me to do. When you receive the parts they will come with material certs on all materials. If you would like to estimate shipping, my zip code is 67203.

I have not received plans yet. Can someone tell me what P/N jam nut is supposed to be used with the Terminal Forks?

Thanks,

Tim

OK everyone, I'm going to coordinate the order with Carl from Comp Tech-EDM. While I had not yet committed to him officially, he was my first contact and my emails with him were leaning in that direction when Tim offered his services. At this point I feel the right thing to do is to place the order with him rather than give the appearance of playing one against the other.

Tim, once again welcome aboard. Your work looks fabulous and I image myself and/or others will be looking you up for parts down the road. I can only imagine what your Hatz will look like when its done


All, I believe the total now stands at seven: myself, Ron Southard, Jud Rupert, JD Gleitz, Amit (Orchardair), Jeff B., and Nick.

I will contact Carl and see how he wants to move forward with handling the orders and shipping. If you wish to have your forks made elsewhere, please let me know... remember if the number of orders drops below 4-5 people the price will rise to $55/ea.

Doug,
Thanks for the kind words. I am sure I will be in touch with questions in the future. Feel free to contact me if you or the group needs something.

Best regards,

Tim

OK Folks, I heard from Carl. This is how it will work: We will each deal with Carl directly - no middle man. Place your order with Carl, make arrangements for payment, and he will ship to you directly. I suppose it would make sense to reference the "Hatz Classic Forks" in your correspondence so he can keep the orders straight.

Thanks for setting this all up Doug!

Just an update... I've forwarded Carl a fresh scan of the fork drawings and answered a couple questions for him. I believe he is all set to go. So if you haven;t done so already, I would encourage you to get your orders in.

mailed my check to him today, but told him I was in no hurry, so if other need theirs first, I told him to move me to the back of the line.

v/r,
Jud
