And anybody else DX Freight?

what that usually means in my world is that not all deliveries were made, due to time constraints I guess
-
• #81604
Probably but they advised delivery between 8.00-18.00h.
-
• #81605
Oh yeah, I'll get those too, best laid plans et cetera

Does anyone know of a link to a history of time trial bikes?
The more comprehensive the better, at the moment all I can find are general overviews of time trialling as a sport and I'm looking more to the developments and prevailling thoughts at different stages of evolution.

Any fabricators or metal workers care to advise a woodworker? :)
I'm trying to solve a problem with a bodged window opening system. Hopefully there will be 4 pics attached (if not I'll add them afterwards). Originally aluminium bar was used to lift a heavy double glazed unit (using 2 motors). The Aluminium bars have deformed and one broken completely. I'm tasked with replacing them but imagine Stainless Steel would do a better job. If it were flat bar I could do this myself, but it has a bend in the end which appears to be important as it helps stop the bar from sliding out of the frame. How difficult is it to get this kind of thing made and who should I ask?

The bend looks to have been done on a press brake. Sheet metal fabricators have these in their workshops, that short bend won't need a high capacity (quick and dirty calculation says 3 tonnes). Being local, I'd ask BMJ, but similar shops exist all over the country.

I need a projector for PowerPoint presentations for work. Presentations are for up to 20 delegates, ideally something that can fit into a back pack, pannier or laptop bag. So not too big or heavy but must project to a reasonable size. Any suggestions?

Thanks, I was hoping you'd have an idea. Is stainless steel the best choice of material or should I be considering something else? I'll ask BMJ. I'm having trouble finding a shop in Fulham, what would you call the kind of workshop that does this type of thing? Machine shop?

Probably sheet metal company rather than machine shop. Sheet metal fabricators.
As an alternative to a brake press and forming from one piece there are a couple of other options such as welding the end piece to the long flat plate or depending on the stress on the end piece it could be pinned and screwed in place. -

As freezing77 says, it's a sheet metal shop job, although many machine shops will also have a press brake as bending is a common second operation. It could be milled from solid, but that's unlikely to be the most economic, and the same would go for a weldment or an assembly with fasteners.

Looking to build up a light race bike for a 5 day stage race in Taiwan, looking for a frame and fork. Don't have time to sift through classifieds/eBay. Any one recommend any decent online retailers of NOS or second hand? Pref is for something industry standard so can get it built up before end of March.
Ta!Exit: 58-61cm incase anyone has any thing in the garage

On a similar note what is the biggest dimension steel bar I can expect to bend by hand, using a vise and approx a meter of leverage?
30 mm wide. 30 mm bend radius if that matters. -

approx a meter of leverage?
30 mm wide. 30 mm bend radiusThis machine says it can hand bend 32mm by 8mm flat mild steel. The load required rises as the cube of the thickness, and as the first power of the width, so cutting the width to 30mm only allows the thickness to go up by about 0.2mm
If you just use a vice and a bit of round bar as a former, you'll get a variable radius bend, you need the roller to form a neat constant radius bend. If you're using anything stronger than mild steel, your capacity will be reduced.

8 mm should suffice, thank you.
Hmmm.... I should buy a bender.

What's a good paint stripper now that they've nerfed nitro-mors? Or can you still get old formula stuff?

You can get the main ingredient. Paging @mdcc_tester

Dichloromethane, probably still available from chemical suppliers, just not as a retail product.

My desktop PC has 4 usb ports on the front. In one is the usb reciever for my wireless mouse. Whenever I plug in my usb memory stick in the port next to it, the mouse stops working. But if I plug it on the port on the other side of it, it works. The hell is going on?
-
• #81625
USB ports are paired on the USB bus. Probably using too much data or power for both ports to be usable in that pair
Does this say the driver couldn't be bothered to come to my address but went back to the depot for an early day?
