Seamly Thoughts

January 31, 2014 in Uncategorized by Fritz

seam sketch
A quick sketch and some comments on some of the types of seams to be found on tents old or new.

Flat seam – probably only modern, very fast to produce on a double needle machine, esp. a double needle chain-stitcher.
Leaks like a sieve when under tension.

Plain – used on secondary seams of the Berlin tent (The panels are assembled out of multiple pieces to make most use of fabric)
Also leaks badly if under tension (but in the Berlin tent they are not structural and there is a liner in case it leaks a little bit)

Flat-Felled – the de facto standard for well made pavilions today. somewhat labor intensive since there are two lines of stitching and some careful prep/folding between stitching rows.
Very water resistant and strong

Flat-Felled with double needle and folder – performs similarly to flat felled, but preferred by many manufacturers because of lower labor (only have to push fabric through the sewing machine once)

Webbing backed – used on the primary seams on the Berlin tent (and I think on the Carlos V tent too. The webbing is the primary structural element, the canvas is mostly just a cover (this probably makes it last longer too)
Very water resistant and ridiculously strong

Integral Seam Stripe – used on the Basel tent, panels are cut with one straight and one bias edge, plus stripe itself is straight grain. The stripe covers the plain seam which is under tension and would leak badly
Very water resistant and strong

Originally I posted this on Facebook, but I thought it deserved being resurrected here.

Round one went to the Ukrainian Spammers…

November 22, 2013 in Uncategorized by Fritz

Despite the captcha, I’ve gotten something over a thousand spam comments in the last month or two. Usually something to do with Tramadol, or Xanax, but with links to what appeared to be legitimate websites. They were coming in at such a rate and I was busy making tents, so I couldn’t really take the time to figure it out.

Today I took a couple of hours to look it over. Turns out that all but a handful of the spam was coming through just two ISPs in the Ukraine. A look at my we stats showed that the Ukraine had grown to be my biggest viewer, countrywise, in just a few months. More hits were coming from Ukraine than from the U.S.

I just blocked the ranges of IP addresses belonging to those two ISPs. I suppose it’s not inconceivable that I could have a legit customer who will now be unable to view my website, but frankly, it seems the risk is acceptable. Despite the flood of Ukrainian traffic, I have yet to receive a single real query from there, and anyway, I’m not blocking the whole country, just two ISPs.

If you left a comment in the last month or two, my apologies for not responding. They got hidden in the flood. I’m working on catching up now.

New sewing machine

August 7, 2013 in Uncategorized by Fritz


This years busy production schedule has resulted in, not only the move to a new shop space, but also the purchase of a second sewing machine. It’s a 25 inch arm machine, which makes sewing in peaks much easier and has an extra high pressed foot lift, which makes stake loops easier.

It also does considerably longer stitches (10mm vs 6mm for the old Consew). This is actually really nice for seams (fewer penetrations of the fabric)

Overall I am very pleased with how it is working out.

New Website

July 30, 2013 in Uncategorized by Fritz

So… it’s finally done. A new website, now with juicy WordPress goodness. This will allow me to do much easier updates and I plan to do a little blog post here, once a week or so. Topics will be all over the place, from pictures of the new sewing machine to discussions and results of my seam and stake loop research. If you have a question or a topic that you think might make for a good blog post, let me know and you just might see it here in the future.

Best Regards,
