|Thread: machine coolant pipe|
Steve, that will do nicely I think. Thanks very much. I tried all sorts of google searches but didn't think to go for a spare from something else.
Has anyone found a supplier of flexible coolant hose at reasonable costs? I'm not talking about the plastic loc line stuff but the metal coil one. The only UK supplier I've found wants £50 plus £17 postage for one but I've found a USA supplier and the same one costs around $20, not sure about postage costs though.
|Thread: Elliott Omnimill backlash|
This will be a job for me soon as well. Too much backlash in a x axis. I`m going to look at fitting a ballscrew but it might be too much work so other choices are make a complete new nut or make a nut holder which will take a separate nut made from round bar. Let us know what route you take and how you get on.
|Thread: Lathe tool holder|
This is the first batch. I will get 5 or 6 from the current bit of bar but I'm planning on making more and also getting the next ones right.
|Thread: Bantam cross slide end float|
IIRC the end float is adjusted by the central nut. It shouldn't be tight to remove or replace.
|Thread: Lathe tool holder|
Thanks guys. It is an aloris type and it does grip the blank tool holder but its right at its limit. I will try out a shim with some Loctite and see how it goes. I`ll need to be more careful with the next batch.
Boufht myself a new lathe quick change tool post and decided to have a go at making some holders. So 30mm thick plate, 240mm long 85mm wide, on the mill surfaced up. Dovetail slot roughed out to depth and started cutting the dovetails. Anyway don't know how I managed it but i`ve cut the dovetail slot 0.5mm too wide. So I really don't want to have to scrap the plate so I could weld up one side and recut it, probably killing the cutter in the process or I could make a shim and pin it to the top of the holder to keep it in place. Any other options to save the bar?
|Thread: Lacquer or light oil?|
Renaissance wax polish would protect it.
|Thread: Digital inclinometers|
I have two of the digital boxes. Larger one at home and a small magnetic type at work. Work one is used for calibrating the bevel heads on our plasma cutters. It is Bluetooth equipped so I can be at the controller with my tablet and set the head up from there. Handy devices.
|Thread: Laser cut plates|
The cad file, either dxf or dwg, will be run through a post processor to convert it to a cnc file, g code or essi for example, which the machine controller will understand. The post processor will also add the necessary auxiliary function codes for beam on, beam off, kerf, speed etc.
|Thread: ELLIOTT OMNIMILL|
Have a look at my Omnimill rebuild album. There are two photos with the vertical head assembly in place without the cover fitted. There is a vertical shaft fitted to the motor support bracket. The cover sits on top of it and has a bolt to hold it in place.
|Thread: What mills have you had|
Centec 2A with the fine feed vertical head. Nice little machine but just too small. Really should have kept it.
Warco GH Universal, just about to go up for sale.
|Thread: pc based dro|
I am looking at fitting a dro to my Omnimill and am quite interested in the pc based version. I have contacted Machine dro about their version and it's availability and am waiting on a reply. So has anyone else used or got a pc based version? I am also wondering about the ability to write different apps for the pc versions if required and has anyone come across this ability? I have a micro pc, touch screen monitor and a few encoders lying around so this would also be a more cost effective route.
|Thread: Norton anti virus|
Nick your right. I've been happy with Norton for a very long time but simply couldn't believe it when I found out the keys are geo-locked. The other annoying thing was their tech support only really being interested in selling me something else rather than fixing the issue.
I`m currently enjoying our family holiday in Orlando, apart from the thunderstorm the other night. It sounded like a bomb going off on the roof. I've never heard thunder so loud. Anyway back on topic. I got an email the other day saying that my Norton subscription was about to expire in 30 days, no issue I thought I`ll fix it when I get home. Anyway using my table last night got a message from Norton saying my trial version has expired and I need to renew it. Strange since I don't have a trial version. Anyway tried to log in and use my existing subscription for the rest of the month but it wouldn't let me, even though I should have been covered for another 30 days. So tried again today with the same results so I contacted Norton on line chat. After about 30 minutes of to and fro chat they eventually gave me a temp key to cover me until I get back home after trying several times to sell me upgrades and new deals for the next year. So basically it comes down to this, If you use Norton and have bought your product from a retailer then the activation keys for it are geo-locked and if you log out of Norton while you are away from home using your device then the protection stops working. In my case it logged me out on its own, Norton runs at start-up and should stay running. The only warning I got was when it said my trial version had expired. I've taken my tablet or laptop with me on holiday loads of times and never had this issue before but it never been near subscription renewal time, coincidence or am I just being sceptical?
So this unhappy long term Norton customer is moving elsewhere.
|Thread: Thread Bare|
Helicoil kit would be my choice.
|Thread: Do you clean your workshop at the end of the day?|
Floor swept and crap hoovered out of the machines at end of each day. Not a total clean each timebut get rid of most of the swarf then spray with wd40 and cover with cloth. Every now and again I go for a proper clean of the machines and floor.
|Thread: What method do you use to find center height for your lathe bit?|
I use the scribed line on my tailstock.
|Thread: Omnimill 00|
Julian, a DRO is planned for the machine but I will need to get my Warco GH Universal sold first but that will be after holidays.
|Thread: laser cut mild steel|
The laser will heat the metal around the cut to above its transformation point and this will create a Heat-affected Zone. The HAZ for laser cutting is quite small and localised near the cutting point. For CO2 lasers Oxygen is mainly used for cutting mild steel but Nitrogen can also be used for high pressure cutting. Nitrogen mainly used for high pressure cutting Aluminium and Stainless Steel. At least that's how we do it.
