DIY mattress pump (plus hot porn video)
Probably the most useful piece of camping kit I’ve made (to date) plus as a bonus you can see pretty hot porn video with this piece of kit in action ;-).
Googling the other day I came across Exped Minipump. This is an awesome idea, but I’m not sure will fit other brands than Exped. They making quite ok camping gear, but unfortunately too dear for me. So I tried recreate more less same product.
I made valve connector with cable gland. Just cut inside to fit valve.
Cut ripstop in a shape of big lollipop as below. (already looking hot ;-))
As ripstop is quite thin I had to reinforce hole with a bit of stronger fabic. Tested and sewn to leg of one “lollipop”.
A “bun” been made with foam I found at office. The additional holes are to decrease slightly volume of the foam (will pack smaller).
In other lollipop piece i made air intake hole, and everything has been put together. Voilà, ready to test. Uhh! Ohh! look at that hot pictures below!
And now promised porn. Do not watch it if you’re under 18! Camera! action!
Final thoughts. Obviously that is prototype or MK1 if you like, just to prove the concept. The pump works ok, but I didn’t pay too much attention to details (as I wanted quickly test it), so I think the air leaks are the main problem. Other than that the test was promising enough to make another iteration in the nearest future.
Mistakes. “Foam bun” is too small, should fill completely wider part. I’m planning to add valve in “hose” part of the lollipop as I got feeling that air been sucked back a bit. The hose is not acting completely as expected, I thought negative pressure will squeeze walls and act as valve). I hoped that stitching need to be air tight so next time I’m going to glue pieces together and than sew it. Intake hole need to be a bit smaller.
Time for Mk2, stay tuned!
Yet another egg timer time-lapse project
Avenir front rack (plus Ortliebs)
I had couple thoughts about distributing weight on the bike. I’ve been thinking about Salsa anything cage with some dry bags. Neat solution, quite like it, but will be a bit tricky to attach it to the fork in my case. What I really don’t like is the price for whole setup. One Salsa Cage in is UK £29 (need two). On top of that is pair of fancy Salsa bags or other dry bags (Porcelain Rocket) with size suitable for the cage, or DIY something.
Other option was Blackburn Outpost cargo cage. This one is around £17 per one. That’s better. Acceptable price, but again, a bit problematic to attach to my fork.
Finally I gave up and started looking for standard front panniers and rack. I’m not really original and went for Ortlieb. As I don’t really see the point paying more for Classic model, I bought “Front City”. Minimalistic design waterproofness guaranteed by Ortlieb and costs 51 quid per pair. Good.
Then I had a bit of dilemma with front rack. I found quite a lot of different designs, but really liked Avenir front rack. Googled about 2 days tried to find any information about dimensions and if they’re compatible with Ortliebs. No luck. The other thing to consider was compatibility with disc brakes. Anyway I decided to purchase the rack and try. I can always return if won’t be possible to fit them. Turned out the rack fits perfectly Ortlieb panniers. So just in case someone is searching for dimensions here we are:
Two things you might don’t like. At first of all there’s no front joining so theoretically they can be “sucked” by front wheel and cause very nasty OTB. But I think as I have mudguards, the mudguard stays will be enough to prevent this from happening.
Once I checked the panniers fit and brakes won’t be a big problem, started to think how to securely attach them to fork. As I expected none of the fittings were ok for my setup and probably most bicycles will have same problem. The internet is full of similar stories as below:
“This front rack is great if you have very thin front forks, otherwise they just will not fit. I am ashamed to say that I resorted to hammering the fixing to make them fit and put dents in the front forks. If you are ordering online check and check again all measurements……now they fit and are very solid indeed !!! “
Well…, the guy gave 2 stars rating the product. On the other hand I’m just wondering why Avenir decided to give only small brackets (U bolts), which in most cases won’t fit? Why they didn’t supply with another, bigger set of U bolts? Or just simply bigger U bolt? Cost for end customer will be probably around +£1.20. Strange.
Anyway at first of all, I needed bigger U bolt. as the one supplied originally with rack was way too small for my fork (the one suplied it’s really 20mm across, nonsense unless you’re owner of old steel frame). After measuring the fork 5 times I purchased suitable U bolt stainless steel 6mm (6 quid) 37mm across. Put some heat-shrink to protect fork. And here we are.
Next I made two spacers instead of original one. The spacers are made of 5mm thick plastic. I’ve chosen the plastic as is incredibly easy to work with, but that can be done using alloy bar or something else.
The mudguard stays eyelets are “sandwitched” between slightly oversized washers (I decided to use same threads as for mudguard stays).
The other option for using mounting points only for rack only is Axiom axle runners or DIY similar thing from alloy sheet (might actually try it for my other bike which hasn’t got eyelets at all)
Everything mounted, medium thread lock applied on all bolts. Done
Keep’em rolling. Cheers.
