Guys firstly thanks very much for your time and help, but it hasn't quite clicked yet!
I think I'll sit down tonight when I'm home from work and try and get my head around it. I did a few years of this and struggled through it, and not used it at all for about 8 years now as done very little...
I could use 7/8" tube instead of 3/4" but definitely no bigger, sorry I'm struggling with the formula above, I've lost myself not having done anything like this for a while...
I want to replace a piece of 15mm round bar with CDS tube of a larger diameter to save weight, I am looking to use 3/4" CDS steel tube, but unsure what wall thickness is required to provide the same strength as the original 15mm diameter round steel bar. Length is 600mm, ends will be TIG...
Hi, I have had some aluminium parts water jet cut for a job, and needed them anodised. I decided to try myself as there will be a slow but steady trickle of these parts to do and it is not economical to have them done professionally with minimum orders.
I set up a small rig along with tanks...
These are not for engine internals, and I will be able to roll the threads myself if required, not sure if heat treating is required though as I dont know if the material work hardens, though I'm sure google will bring some answers up.
Hi, I'm very new to titanium, and just want to know if 6/4 is ok for machining bolts/fixings or is it brittle? I ask as it is easiest to obtain and have been told to watch out for different grades with regards to different uses.
The fixings will be subject to some shocks etc in their use and...
Thanks desertfox, have printed off your file and will have a good read over it tonight. All interesting stuff for me as I dont get this involved normally!

Ah of course, thanks. The washers will be hardened approx 3/4" diameter and will not embed, they are standard items for other studs which do not have a reduced shaft so do not stretch much if at all.
Hi, just a quick one- I am using cartridge heaters in a job for myself and due to awkward installation it may be necessary to weld around them.
They are being inserted in thin wall aluminium tubes and require a cap welded on the end (opposite end to wires), due to the other end of the tube...
Thanks guys this is excellent help for me, the studs I will be making from EN24, heat treated to V grade- the properties are shown on this page http://www.westyorkssteel.com/EN24.html
Hi, not sure if this is the right forum to have this in- but I have had some gaskets water jet cut from copper sheet, 0.5mm thick which has a left large burrs around the cuts on the rear (and a small lip on the front).
What options do I have for deburring them- I have looked into the regular...
The other part is how much force the expanding aluminium is capable of producing, is there a relatively easy way of working this out? In addition to the strength of the stud this should enable a stretch calculation?
I always try google before posting on here but the problem is getting few...
Thanks very much. The application is actually a cylinder head, and what I am doing is making some studs of my own, so I'm trying to get a good mix of the right stud shaft diameter so that it can elongate with the aluminium, so that when it cools down it still has clamping force. The problem is...
Thanks, that link says it is approx 13 micro inches per farenheit, as in 13 thou? Seems too much as I probably have the wrong end of the stick!
Basically it is a big block of ally, with several holes going through one plane, which is 65mm thick, I just want to find out how much it will stretch...
Hi, can someone please help me with how to calculate the expansion of aluminium with heat? I know the alloy will probably affect the result, but I'm just after a guide amount at this stage. For reference the piece in question is 65mm deep, and temperature change will be between circa 10degrees...
It's not just me then! I'm trying to remember all that I learned at college 8 years ago as since then I've been doing dirty engineering and automotive stuff!
