OK as soon as I get my lathe parts, and as promised before, I will make you a set. Free and for mahala. It should be soon but like the engineering shop owner said "There are three factors - speed, quality and cost saving- choose two." I chose quality and cost saving. I will make a V2 with knurling and everything. (or try at least)

Yes correct. It is a 5mm thread with a 0.8 pitch. The thread portion is 7mm long on the caliper side and 5mm on the brake lever side. The size of the "screw head" portion is 6.5mm in diameter and the depth of the head is 2.5mm but it would probably be better at 3mm long. On the other end the pipe fitting has a diameter of 4.2mm and is 10 mm long. I left a rough cut finish for the pipe to grip on and it works perfectly. I really pushed the syringe very hard to see if the pipe would jump off before bleeding the brakes as I did not want to get brake fluid all over the frame. It can easily handle the pressure required to push the brake fluid up from the rear caliper to the lever. The O-ring has an inside diameter of 3mm and a wall thickness of 1.75mm. The pipe is the common type that you get at pet shops and Builders and has an internal diameter of about 2.9 - 3 mm. I suspect it is polyethylene. I hope this is clear enough in the absence of a drawing.

Sadly not. I simply copied the dimensions from the bleed screws with a micrometer. The other end was done on the TLAR principle. (That looks about right) I’ll measure the dimensions and post them.

Anyway RomP. My offer stands.

Well spotted. They have really stood up well to some very hard use!!! I would most certainly buy them again.

Most of the time I will buy a tool when I have a specific need for it. This little socket set was an exception. It is a 1/4 inch drive set. I thought I didn’t really need it when I bought it. Only after starting to use it did I realise how much I actually needed it. It is surprising how much I use it now. Especially working on bikes, lawnmowers etc. It also works great when undoing and tightening pipe hoses used mostly on cars and irrigation. No more struggling to keep the screwdriver tip located on a screw head that is trying its utmost best to rotate away from you. All I added were some hex bits.

This is probably the tool that surprised me the most. I bought it very cheaply at one of those china marts as part of a set. I was actually looking for a short 1/2 inch drive extension I wanted to sacrifice and was not prepared to use a Gedore extension. Nowadays this is the first tool I grab whenever I need to use sockets. As a matter of fact, it is now permanently living in my Gedore socket set. I find it extremely handy to use. It is quick to swap a socket from one end to the other when you need leverage or reach. Attaching a short extension to the short end gives you both reach and leverage. The knurled shaft makes it quick and easy to turn bolts or nuts by hand. I hardly ever use the ratchet now.

Thanks NC_lurker. I will pm you to make arrangements and definitely pay it forward.

Does anyone perhaps have a SRAM X-7 3X shifter for me? I am willing to pay. Thanks

Even the Park Tool bleed kits use plastic syringes. I had the same challenge and then decided to make my own. Basically I copied the dimensions of the bleed screw on the one end of the fitting and provided an adapter/protrusion for the plastic pipe on the other end. And obviously center drilled the fitting. The cost was minimal and it works really well. I used two solid brass wall plug pins I kept for “one day”, syringes from Dischem and some plastic pipe I had lying around. I could bleed the avid brakes on my bike perfectly. I was surprised to see how strongly the plastic pipe attaches to the fitting as is. I still need to find clamps to close the pipes off and am looking for something suitable, but actually found that I did not need them. I am sure I will stumble across something as one would be less likely to spill brake fluid on the bike parts. Brake fluid and paint don’t play well. Unfortunately I am not quite finished restoring my lathe but hope to get the balance of the work from the engineering shop this week still. I would also need to get some brass stock as I do not have any more plug pins lying around but I would be happy to make a set for you. Another point is that they use viton seals with the systems that use brake fluid which breaks down if contaminated by mineral oil/petroleum distillates so it would be highly advisable not to use the same set for both. Unless you have some way to really degrease the set. Proper wash in methylated spirits maybe. The fitting with the longer thread screws into the caliper.

Hi Does anyone know why pages 2 and 3 of this thread do not display? Thanks

Hi. I am interested please.
