|Thread: Dore small boring bars|
towards the bottom of the page is more info on tuneable/anti-vibration bars
You can get tunable boring bars, damps out the vibrations. **LINK**
Some bars are filled with fluid/springs. I've used some at work 25mm dia bars working 300mm deep and no chatter!
|Thread: Workshop Walk|
|They are multi spindle pillar drills. Spent 7 months of my apprenticeship on them......|
But one question remains for me!
Was it washing machine and if so, what's it for?
|Thread: Centre drilling long length, small diameter bar|
|I like the idea of bearings on the bar. You could even use 4 or 5 and run decent speeds.|
|Thread: Unexpected machining content on the TV|
I thought it was his own, (very good), business .
|Thread: Fusion 360 Knurling - Efficiency?|
I spent some time yesterday trying coils, but couldn't get it right. I'll be having a go later. Thanks
|Thread: Bored. 5 weeks since been in the shed|
|Thank you for the kind words. I've started to draw up the fixator in Fusion360, but struggling to concentrate. I intend to 3D print it when it's finished. I've already added a lot to my long list of "roundtoit" jobs!|
|Well, the boredom and frustration are well set in now. Not been able to go in the shed for 5 weeks and could be 5 more MONTHS untill I can return! I can't even manage sitting at a table yet. I've had a fairly complex op on my knee,( fused knee, external fixator and muscle/skin grafts). Thankfully I only had 2 1/2 weeks in hospital. Fortunately Mrs jimmy is an excellent nurse! Moan over!|
|Thread: Feedback Sought - Beginner's Series|
|I'd be happy to see it. I enjoyed the special magazine. Sometimes it's good to be reminded of basics|
|Thread: Car problems|
yes, what was the problem and have you sorted it?
|Thread: 3D printed soft jaws|
|I quite like the idea of printing jaws with the correct profile, leaving small skim on face and bore/od.|
Extra reinforcing webs could added etc.
|I would go for far thicker perimeters and greater infill. It's certainly something I'll think about using|
|Interesting, now the shape has been explained. I use fusion360, modelled threads print very well. I've managed to get away with just running a grubscrew through the part. I use PLA. I've made quite a few special form soft jaws. I'd not thought of printing some, untill now!|
|Thread: New Axminster surface plate?|
|I bought one of the small ones from axminster, on a special offer, about ?28. Only complaint I have, is I wished I'd bought the bigger one!|
|Thread: Does anyone know how many small lathes are sold a year??|
Bored and up early, (can't sleep, major surgery tomorrow ), looking at lathes on ebay, just got me wondering.
How many mini-lathes do you think are sold in the UK/world a year??
How many "home shop" lathes etc??
How many Myfords were made/sold in UK/world? (some one must know that one!
I'll get back to twiddling my fingers
|Thread: Model Engineers Workshop Lost The Plot|
Lost the plot?
You probably have. Or been on the mardy nuts
|Thread: Acquiring a wedge type quick change toolpost|
I've got them on both my lathes (model 000 and model 222).
So much better than the piston type!
|Thread: Prusa i3 Build|
I bought one at the Warwick show, last year. Been ok, but took some fetling. They are only as good as the build!
Not sure if I would buy the same again, ( it was £350). But the "delta" design is quite a good one.
Whatever you get, NEVER, NEVER buy cheap filament, use a trusted supplier.....
|Thread: What Did You Do Today (2017)|
I finished the rotary broach kit.
Quite chuffed with how well it works.
Only grip is the silversteel in the kit was the wrong size! (8mm is the only size I didn't have in the stock drawer!, but a quick trip up my mates sorted that!)
