Brian,
Started a new youtube series two weeks back - there was a bit of demand to see these parts ''live in person'' so to speak - have written many tech articles on them in the past.
Hopefully the videos will bring a bit of life and scale to the parts!

Imagine a multi cylinder air compressor - lets say inline 4 as example - bores same diameter, single stage pumping, 90deg journal offsets.
On my Ingersoll Rand inline twin cylinder compressor single stage the journal offset is 180degs - both cylinders output into a single Y pipe that goes to...
So I decided I would share these links - they are my writings and studies of Cosworth F1 Engines + A Brian Hart F1 Engine over the years. The recent thread on Engine cooling in the other section made me think of them. They are mainly based on the Cosworth TJ V10 and CA V8 F1 engines which I...
Just incase some of you may not have seen this,

Too bad its not reed sensing for rpm which would be lower energy for remote sensing/IoT but still...
Brian,
Involved with a tablet stylus pen.
A run of 'looks like', and if possible 'works like' items are required.
I am making them using vacuum casting/pressure method pouring into silicone moulds.
I had found a research paper stating that doping casting resin with 20% graphite power works fine and...
Its soon crunch time when I'll need to get a cnc lathe.
I dont do a huge pile of lathe work but I need something that can turn out 50 pieces with a few hrs notice as sending time critical stuff off site is now driving me mad with delays.
Been keeping my eyes open of late when visiting...
Stumbled on these tonight, some great stuff here. I had thought about posting them all in a more 'current' section so that more might see them but was afraid they might get shot down by some.
Information is solid even today.

Hello all,
Im currently doing a lot of short run castings(batch numbers 40-100) requiring an- fittings of various sizes. The ones Im dealing with are an-8, 10, 16, and 20. These are coming to me pre-made with an approx thread length of 10mm across all the an- sizes. Im not fully up to speed on...
I hope this section is most suitable for this,
I am redesigning extremely rare rack internals into a new case/housing. The old case broke due to it being a prototype(marked as from factory) which had been I guess taken from the normal line, and brought into the factory workshop for some...
My father always says there's no such thing as a stupid question if you dont know the answer, but today, Im feeling stupid regardless asking this question. You may have gathered I dont know much on this subject but do wonder about it.
If I have a scale model of a car, lets say 10 times smaller...
Hello all,
Im sure many are familiar with this type of charger. It uses 3 traction rollers instead of gears in a planet arrangement. The main annulus ring is heated, and fitted over traction rollers, it shrinks and provides the drive to rollers and onto center shaft. The annulus ring deforms...
Can anyone tell me the material/steel spec for the wire used in the wire belt located in the sole of the tyre?
I'm designing a machine to cut soles to width once sidewalls have been removed, and the ring cross cut. Id like to know what wire it is Im trying to shear when designing/spec'ing the...
A great video showing everything, from start, to finish, and everthing they faced in-between.
Remember this is a bonded aluminium chassis, and was pretty new in mass production terms.
MMC rotors are interesting too,
You wont be disappointed thats for sure, its nearly 2.5hrs long.

Brian,
My supplier can give me both in 'any' size.
I have not yet made my mind up if I'll tig, or gas weld as at the minute, from a lot of research gas seems to be more favorable (albeit a little old fashioned) for a few reasons. The main one being, heat treatment and the smallness of the HAZ with...
Can anyone point me to a supplier for said sand and binder systems for use with Al alloy.
Supplier must be in the Uk, and be willing to ship a min quantity of 1/2 - 1 ton + same ratio of binder to Ireland.
Thanks in advance,
Brian,
Is/was the harmonic drive a descendant of Fergusons idea?

Skip to 6.50 in the video below for what I think is Fergusons doing, but Im not sure if Ferguson ever had an outer gear ring in his plans. But, looking at the drawing below...
