Hi
Thank's you set us on the right track. The CMOS battery was flat, jumping the power on pins started the PSU but it still did not boot up, but shorting the reset pins did get us to the set up...

Hi
I have an Ajax CNC (from the USA not UK) DM45 mill which dates back to 2006. All has been well for many years however I recently moved it to a new location. Since it was moved I have been unable...
Hi
does anyone know if Ajax CNC in the USA are still going?
Cheers
Hi
Are you going to fit a superheater to the boiler??
Hi David
It looks like in interesting project you have on the go. steam engines use either a mechanical lubricator (oil pump) which you can buy off the shelf, Take a look on page 47 of...
Hi
To me there would seem to be a mistake on the drawing. If you look at the shaft at the other end of the motor it is dimensioned as 0.8750 to 0.8745 or in other world a 0.0005 span, which is what...
Hi Guys
i have to make some leaf spring suspension shackle pins for an iveco truck. the pins need to be case hardened any sugestions for the best material to make them from.

Hi
make sure you use a sharp tool ones for aluminium should be fine and don't take very light cuts. it catches fire when the swarf is very fine or worse still almost a dust and the tool is rubbing...
Hi All,
does anyone know of a supplier of off the shelf thread mills, 40 tpi, with a 55 degree whitworth form, perferably in the uk.
Thanks in advance

Hi,
My gut feeling is that it won't work due to the amount that the steam contracts when it condenses. Saturated steam at 100 psi has a volume 237 times greater than the water it came from. I can't...
ok ignore that last post i just had a better look at the pictures,
This is going to sound real silly, but are you sure that it has'nt got a left handed thread. I had a similar problem on a ford suspension bolt, it was easy when i turned it the other way.
Hi Guys
Thanks for the info so far. Just to clarify things I have a splined shaft which i need to copy for a customer, I can't get hold of the female part to check the fit of the part i make, so my...
Hi Larry,
I have had a DM45 since December last year. I spent about 6 months looking for a machine of this sort of size and the DM 45 was the only one I could find. Basically it is a Chinese built...
Hi All
I have got a one off job that requires an involute spline cut on one end. I have a sample that i need to copy. my plan is to draw out the profile of the tooth, so i can m/c a cutter to...
Hi All
Just a couple of points, don't be tempted pump it up with air, if you do and a weld fails, it will be like a bomb gong off. If you use water it is safe, because as soon as you get leakage...
For me a 12’ long bar feeder would not be an option, by the time you add on the length of the machine you would be looking at say 19’ minimum in length, that’s a lot of space. Give me a 1 meter,...
Hi All,
Haven’t had much time to look at this, but had a quick look tonight. The Z axis numbers are identical for each pass, so that’s ok. Back plotting in NC plot seems to show the dimples. A quick...
Hi All
The dimples are about 0.030” in dia and are not inclusions in the weld they were created by the cutter, yep it was TIG welded, not alu brazed. I think the problem lies in the digitizing, I...
Sorry for the confusion. The program to machine the shown area was digitised from another part of the same crankcase. The work zeros were then shifted and the welded area machined. Yes the material...
Hi All
I had my first go at digitising the other day, and whilst the results were fine for the job in hand (machining off weld from a cracked crankcase) the machined are had lots of random little...
Apart from spreading abrasive dust all over the lathe, the biggest problem I can see is ensuring the wheel runs true on the grinder. Most wheels are shaped with an optidress or similar mounted on the...
Personally I use Autosketch, and for preference V2.0 (which is quite old now). It does not have all the whistles and bells of its big brother (Auto CAD). The reason I stick with it is because it is...
This is going to sound real silly in this high tech CNC world, but put a small bit of cloth over the hole before you countersink it, no I’m not away with the fairies it dose help :banana: . Run the...
Hi All,
does anyone know of a UK supplier who produces a 440 volt 3 phase to 220 volt 3 phase transformer, current draw is up to 15A/phase, off the shelf? It is needed to run a US built machine here...
Slightly off thread I know but I was always taught to bore a hole before reaming to insure that it was straight and to a uniform size. This was because drilled holes are seldom 100% straight and to...
Hi,
Any one know of any wax suppliers in the UK, I’m having trouble finding one
Cheers
:confused:
Hi All
I worked for the UK MOD doing R&D during the first Gulf War. There was so much work to be done and everything was needed yesterday, that initially people were working 16-18 hour days 7 days a...
Hi All
Here are the power constants (Kp) for different materials, which you probably have anyway, but there is probably a direct comparison since the cutting forces are directly related to the power...
Ah ok,
I have formulas in a book on calculating the power required for given materials, cutters etc, but I’m not sure they would be much help. I can post them if they are any use to you. You can’t...
