The pattern of holes is symmetrical, its looks like they will match up if bridle is folded with three holes either side. It would be interesting to check if the damage is in the area that is folded back across flap 2 when closing the container. If so then it is likely that the kill line has not been cocked well enough and the slack is taken up on deployment, the burnt area will be under pressure between flaps, stiffeners and binding tape.

I have a Singer 211 which is a walking foot machine. I find that it is only really useful for heavier container work or multiple layers of webbing etc. The machine I use most is my 20u, its a drop feed machine, will sew canopy patches just fine and deals with almost any other work. After changing over the feed dog and foot it really works well for any zig-zag work. A good choice as a first machine. I have a twin needle Mitsubishi for all my binding but I bought that in the greatest deal in the history sewing machine purchases! I had a 31-15 once, regret selling it now, top machine.

I have had two 20u machines and used them for just about everything. Also here in the UK the thread is sized on a metric scale, 40 metric is the equivalent of E thread but is slightly heavier and I have never had any problems. I use size 21 needles for most container work. I have given up using mechanics to fix any problems, last two were useless and in the end had to figure out solution myself.

Could you post a picture of your main pilot chute. Just curious because that type of set-up was subject to a UK safety notice in 1984 after a pilot-chute in tow when the handle and lanyard entangled with the bridle.

A lot will depend on the size of reserve that you require and the type of main canopy, not all 190s are the same volume. Try this online sizing calculator. http://vos.uptvector.com/vos/v3sizing.html

I am sure your Advanced Packer / Rigger will be able to sort it out for you. However the best source of information is the manufacturer: Paratec GmbH Flugplatz Saarlouis-Düren 66798 Wallerfangen Germany Email : [email protected] Phone: +49 (0) 6837-7375 Fax: +49 (0) 6837-74373

Its simply too much canopy bulk in the ears. Reducing the amount of bulk at the top of the freebag (and reserve tray) will help to solve the issue.

The PC, freebag and toggles are from a Wings, the canopy is a PD reserve.

I have attached a page from the PD manual that shows the best way of attaching Dacron line to a toogle. (If however you require a loop for a base gear set-up as someone else has suggested then your best bet would be to ask on a base jumping forum.)

Got what I required. Thanks.

I need to check some measurements on a Javelin OJK, any riggers or owners out there? I won't be able to call Sunpath for another 5 hours.

I have made & fitted the "Chutin Star" style blocks on a few risers, they work well and are hidden when packed.

Using anything other than round point needles on any rigging work is a bad idea and there are proper solutions, needle scarf size, depth of thread channel, thread lubrication, condition of the hook etc all play part in producing a good stitch. It may just be the quality of the needles you are using. I have no problems sewing through the materials you have mentioned and I use round point needles (size 21) with my 20u. I use a LT2 twin needle for binding, I have just produced a main pin flap for a Javelin, this is made from several layers of cordura, ballistic cloth and .060 HDPE and it is fine. I have attached a link from needle manufacturer Groz Beckert, it gives you some idea why you are getting problems and a product they have developed as a solution. http://www.groz-beckert.com/website/media/en/media_master_371_low.pdf

I use some clear acrylic sheet bought from the local hardware store and have covered the edges with adhesive foil tape, a bit like binding. It works well and has lasted for many years now. I have also used thick mounting board for the art store but this is not transparent.

UPT use .020, .040, .062 MDS and .060 poly. Sunpath use .030 MDS and .060 poly. I recently bought small amounts from both companies. Can also depend on the model (year) of Javelin as they have made small changes many times over the years, especially on the riser covers.
