Thread: The cultural status of engineers in the UK

In my book, an engineer is someone who has completed at least to university degree level.

Nonsense

Thread: Creality 3D For Christmas - Impressions so Far
03/01/2020 07:10:09

Andrew, I just had to have a go with my Aldi printer!

I drew up the same 25mm square with .4mm walls.

My Cura slicer (3.4.1, I'm happy with this version and have resisted updating), would not print the walls (I checked the layers, before printing).

I tried your tip of 0.39 wall and it worked! I have a wall of 0.4 to 0.5 thickness. Quite impressive for a printer that cost £150 (this one is Aldi's black Friday sale one, my other was full price).Printed with PLA filament (cheap stuff- see below)

I have found that filament is the biggest factor in getting good prints. I have bought some packs of 25 different colour samples of PLA (10M long, so good for most prints) and not had any problems. Some filament from 3DQF was that bad it went in the bin. I can recommend 3Dfilaprint for good quality PLA.

Andrew, I have ran a rear toolpost on my SC4 for years. I'll sort a picture later.

I mainly used it for a production job, needing two tools.

Axminster do give a 3 year guarantee (parts and labour).

Thread: Bandsaw woes.
21/12/2019 04:17:40

When I got my Chester H110 bandsaw, I had a lot of problems with the blade jumping off. The cause turned out to be the guide bearings!

3 out of 6 collapsed within 3 months, since then I have had no trouble at all!

Thread: Slip gauges
14/12/2019 11:33:50

I've ended up with a metric and imperial set.

A slip gauge accessory set is very worthwhile addition, as it turns the slips into an extremely versatile measuring tool.

Well worthwhile investing.

Robin, 333mm is a pack of 5.

Some smaller sizes are for packs of 25.

Thread: 3 in 1 Lathe/Mill for $139? Early chistmas present perhaps?

Clearly a scam. Much like the ads on Instagram!

Thread: Why mostly manual cars in UK
07/12/2019 12:09:20

Volvo don't recommend an oil change, unless used as a taxi......

I've been driving automatics for 30 years.

Modern auto boxes are quite amazing.

Why anyone would want to have to mess around with gears is a mystery to me......

I have very good results with that same stuff from ebay.

I really wouldn't bother making my own!

Thread: Breaking bandsaw blades
02/12/2019 17:46:42

I can't help with any advise, other than to say I leave my bandsaw tensioned all the time, with no ill effects.

Thread: Recommend a Small Parts Lathe for 2k.
02/12/2019 08:29:57

The SC4 has been a more reliable machine and has done a lot of work for me.

The Crusader (mine is the deluxe) is a more capable machine. The DRO fitted to this is very useful.

I have found that the two lathes actually compliment each other very well.

As for reliability, the SC4 has done thousands pf hours of work and not really gone wrong, on the other hand, the Crusader has given me enough trouble with the motor, to push me in to spend on a VFD and new motor.

If I was to but one from business use, I'd seriously consider the Chester Variable speed 415v version.

I have both the SC4 and Crusader lathes.

Very happy with both.

Good luck.

Thread: which lathe?

I have machined Olite bearings a few times. Re oiling is not a problem and actually standard practice link

Thread: Long bed lathes affected by the tide
29/11/2019 14:46:04

I have heard this. Could well be true.

Some very highend machines have to have their own "slab" so that other machines vibrations don't interfere with them.

We once had trouble on CNC lathe with surface finish, eventually traced to a big mill at the bottom of the shop!!
