Thread: Nozzle Bores

I have ran 0.2 nozzles and got a fantastic finish, but the time taken was not worth the compromise, likewise, a 1mm nozzle is fast, but the quality ain't good!

0.4 does seam to the right mix of speed and quality.

I've come to a similar conclusion ,though for small objects and figures the 0.2mm nozzle with a 0.1mm layer height is outstanding. Tip if the items are very small print 2 of them, gives one a chance to cool down between layers and cuts heat distortion.

I also came across an article [can't find the source now !] that recommended for printing flexible TPU type filaments to use a 0.5mm or larger nozzle to avoid high pressures in the extruder and failure of the extruder gear to feed the soft filament.

Good advice. I tend to print a Ø20mm block when printing threads, as this does allow the layers to cool fully.

I buy my nozzles from China in lots of 10. I always check the nozzles and thread, not had any problems (so far).

Thread: What filament material do you use on your 3D printer?
26/06/2020 19:26:32

I use PLA 99% of the time.

I get filament from HERE for important prints, no filament has ever failed from them.

For general printing, I have had very good results with the packs of 20 x 10M filaments from ebay. 95% perfect prints!

My printers are the Aldi specials. Like Neil I rarely use ABS due to smell. TPU is fantastic stuff, but can challenging to print!!


Thread: Best places to buy metal for machining
16/06/2020 19:13:12

Running the engineering department can have its advantages!

If I need something specific, I go to the places mentioned here and ebay.


Thread: Mild Steel Rod in Metric Sizes

Try Macc Models. They have a link on the right hand side.


Thread: Gadget for capstan tooling
12/06/2020 19:57:19

I have years of memories using roller boxers.......


Thread: Compressor inspection
10/06/2020 19:09:48

I had the same thoughts a few years ago about my 16 year old cheapie.

As has been said, it'll just leak when its knackered.

If you are worried, just replace it.


Thread: Hermes Parcels
10/06/2020 18:53:56

I have nothing but praise for Hermes, never had a any problems.


Thread: Keeping Shop clean
07/06/2020 09:54:54

I use a Henry hoover, not any problems in 9 years of use.


07/06/2020 07:38:58

I've only got a small (8 x 10 foot) shed that is filled with stuff. I just accept that the mess will happen and clean up after!


Thread: Questions about lathe power feeds.
07/06/2020 07:33:34

I have power feed on the cross slide on both my lathes. Just about the only time I use it, is for facing soft jaws.


Thread: DIY drip feed oiler for cutting fluid
06/06/2020 15:42:57

Excellent, thank you for sharing.


Thread: Machining Ceramic material
03/06/2020 11:24:30

Nick makes a good point. Some of the gears I had to bore out, were only half inch thick. We had bore half way and turn the part around, as boring through just burst the gear!

Michael is spot on.

I spent a couple of months, 20 odd years ago, boring out some ceramic gears (made with under size bores).

Diamond inserts were the only thing that worked.


Thread: Surface Plate & Height Gauge recommendations
31/05/2020 16:15:05

I used various granite work tops for years, 3 years ago I treated myself to a granite surface plate, 450mm x 450mm x 90mm.

I probably don't really need it, but I do like it!


Thread: Workshop Gloves
30/05/2020 13:01:17

I wear nitrile gloves all the time. I developed very bad dermatitis, 25 years ago, that took over six months to clear up.

Work assessed the gloves as ok.


Thread: Tapping stainless
29/05/2020 17:11:43

I tap and die a lot of 304 stainless (mainly M6). I use Rocol RTD liquid, I've tried loads of other cutting oils, but none work as well on stainless.


Thread: Machine Tool Peripheral Hoists
29/05/2020 03:39:52

I think that it would be fine 1 1/4" shank tooling could generate a hell of twisting force. The loading is not a "shock" load either.


Thread: 5C collet chuck, direct mount D1-3 or backplate?
26/05/2020 16:35:22

I'd be inclined to follow Clive's advice and go for an ER set up.

I have a ER40 set up, more versatile than 5C, in my opinion.
