Your answer was not helpful in any way. Rigger forums and sailmaker forums are normally the best as I doubt you'd find any tailors using a machine like this. -Michael

Finally got my new sewing machine (251-3). It requires some lovin before it will work. First of all it's not timed so I've been trying to get that done according to the manual. I noticed that one of the thread loops was missing and the other was badly bent. Can you guess what happened when I tried to straighten it? Yep, snapped off! You can see the nub just above to the left of the tensioner. Can anyone tell me if these steel loops are threaded or press fit? I may be able to knock the broken off piece out of the hole but not if it's threaded. Next question, what's the second one on the left supposed to look like? It's missing and the manual doesn't show a clear pic. No problem for me to make one I just need to know what it should look like.

Weren't they all induced by nasty thing you call a canopy? I had 3 saves in 10 packjobs last year. -Michael

I think one was seated on a plane at the wffc when the pilot screwed up and pressurized the AC. -Michael

How about wax crayon? Most bridles around here have been marked with crayon to denote the last X feet as per the manufacturer's packing directions. -Michael

From the engineering point of view maybe this Vigil III is just some software changes to improve these points of criticism. As any engineer understands these things take a lot of time to properly test and audit. On one side you have people saying "sheesh it took them THAT long" and on the other side you have people saying "2 revisions in 5 years, that's scary". By the looks of it in the 3 expired cypress 1's I've cracked open they seem to change the entire board inside every 4 years. Everyone out there is revising and improving their products. Some tell you and some don't. As long as the changes are properly tested I've got no problem with that. -Michael

Normally you'd take it to the rigger who packed your reserve originally. I'm not 100% sure on British regulations but in Canada and the USA the rigger who sealed the reserve could uninstall and re-close without having to do a complete repack. Otherwise maybe you could have a repack done and then have the serviced AAD re-installed avoiding the second repack. In any event if you are not a rigger and are not experienced in such things it's probably not a good idea to open it up. -Michael

Another manufacturer, the thread would probably just vanish and the entire problem would be explained as a user who did not switch their fine German piece of equipment on correctly. Now that time has passed did the unit shut off? It did not start up properly so it should probably be removed and sent back. -Michael

Very few times have I remembered to turn the vigil2 off before sticking it in the car for the ride home. Never had any problem with it. Have spoken to many people who do the same and they haven't had problems either. I understand it is possible to have a firing when I slam the car door so if that happens I'm willing to accept that my screwup caused it. -Michael

Please use the search feature this has already been discussed to death a few times over.

I made some plastic seals a while ago. Only for environmental reasons and because I was bored on a cloudy day. I'll see if I have some photos. They are still used with a normal seal press. -Michael

CSPA solo license recognized by USPA?
hackish replied to chester's topic in General Skydiving Discussions
It is not recognised, but go talk to the DZ. I jumped in Deland on my Solo. They checked my logbook and asked a few questions that's it. I think I had about 35 jumps at the time. Someone else I know travelled down with 15 jumps and had to do a checkout jump with an AFF instructor. She was happy and gave the OK. Hope that helps. -Michael -
Not even that exactly. Consider the valve springs in my engine. Made of the same basic material. They're moved millions of times yet after 100,000km are still in spec. It's not the movement that weakens the spring. It's manipulating it beyond it's yield point. If you bend it further than it's working range so you end up with some permanent deformation then you are degrading it. I agree with most comments here, keep the reserve packed! -Michael

Weight Change Affecting Freefall
hackish replied to PeregrineFalcon's topic in General Skydiving Discussions
Interesting. I gave up 10 pounds of my free wingloading increase over the winter. Doubt I'll notice it but I have often wondered how much an experienced skydiver would notice weightloss. -Michael -
I think the problem with small radius hangers is that it could damage hard cable housings in the risers. While I'm not 100% convinced on that point I do feel that it might deform the risers slightly if you hang your rig like that for an extended length of time. A piece of 2.5" black ABS solves that problem. -Michael

Since an elliptical canopy is more efficient, I expect it will fly faster than the same square footage that is perfectly square. If so then I would expect smaller openings on the nose would be needed to maintain canopy pressurisation. With smaller openings the wing should be more efficient with less drag. I don't really know, just making an educated guess. -Michael

I seem to recall the test was 1000lbs MBS. I don't have the figure under my fingers and I can't think of exactly where you'd find that. The figure I got came from a master rigger who was discussing building a RDS with me. -Michael

I have a sense of humour. Sometimes it just does not translate well to the interweb. Some days my sarcasm is thick sometimes not -Michael

I have written an article about it. I am still waiting for some details from manufacturers so my facts an analysis is as complete as I can manage. I am also going to speak to an aeronautical professor who is interested in my findings so at least the technical info can be somewhat reviewed before it is published. -Michael

I was playing with some GPS hardware and recorded 100km/h (63mph) unfortunately it didn't have a very good fix on the sats so I can't say how accurate it really was. -Michael

Benefit to the Airport for hosting DZs?
hackish replied to TaeKwonDoDo's topic in General Skydiving Discussions
You may have to get your local rigger to certify it as spend-worthy. -Michael -
No, scrum the point here is that a jumper with 1-2 jumps should trust that the main was packed correctly. Unless they pull a me and get their rigging ticket before their license I wonder if they would be qualified to know a good from a bad packjob from watching. I agree that gear checks are important but worrying that the packer didn't do their job correctly? Obviously I'm a nitpicky bastard who stood around and asked all the questions nobody could answer until someone finally told me "if you want to know that why not go get your rigging ticket". So I did. There is still 2 damn feet of snow on the ground. So no, the '09 season hasn't started yet. Hmmm. I wonder if there are any winter jumps going on in TO this weekend... -Michael

Would you jump this? Look at the pictures, then answer.

Check the inside of the grommet for burs. -Michael -
I really think the term comes from a want to be non-commital about it positively functioning perfectly while freeflying. Oh but your honor it says here it's free fly friendly, not free fly guaranteed! -Michael

I packed me a lineover once. Only thing is I know 100% for sure it was packed properly. Was just a weird opening where one side took a while to inflate and when it finally did there was a line over it. Sometimes shit happens with a properly packed canopy. When I was the new kid on the block I'm happy I was made to feel that the rental rigs were carefully and properly packed so I wasn't afraid that the packers were incompetent and that it was likely to kill me. -Michael
