Steamchick- many years ago when I worked in Whyalla in South Australia, I had a car with a small (273 cu in) v8 in it. I fitted an accessory water gauge and was always intrigued to see the water temperature come DOWN to running temp. after the car had spent the day out in the sun. It was...

My own take on this sort of fragmentation- I think it is pretty ordinary at best. To see what happens when a forum goes down this path, take a look at the prusa 3d printer forum- they currently have 535 different sub-forums and seem quite happy to make even more. And as for not allowing...

"I wonder if that is a part of their decision to frequently ride at speeds slower than most on Motorways? At least in my view" Steamchick- we used to say the reason for their slow speeds was they didn't have to walk back as far to pick the bits up that fell off.............

When I wrote my (arduino) code for my dividing head some years ago- and after numerous computer crashes, I now no longer have the source code!-I calculated each step from scratch, as I figured that way I won't accumulate any error. Seems to work, I don't have any measurable accumulated error...

And Steamchick, you have given me an idea- I wonder if a jigsaw modified to hold a small file ,and upsidedown in a simple stand, could be pressed into service as a poor mans filing machine?

I bought my bandsaw about 15 or 17 years ago, it continues to be my most used tool. Not long after I got it it went from cutting perfectly straight to cutting more and more on a slope.. I worked out that the teeth on one side were slowly loosing their set. The teeth were running on the drive...

Ray, take a look at Graphogen- https://www.graphogen.co.uk/index.asp?pageid=644920 We used to use it a lot when assembling our old british bike engines in much younger days. Coat the bearings and bores with it before assembly and the loctite won't be a problem. But don't do what a friend did, he...

Tug40 said "And BSA stood for Bastard Stopped Again." Thanks Tug40, that made me laugh- I hadn't heard that one before. Though back in the 60's it could have applied to most of the pommie bikes we owned- even the new ones!

As they say- the trouble with standards is there are so many of them! If I remember correctly, the BSA Bantam (early pommie two-stroke motorcycle) had some 37 different threads on it, including several that were BSA's own design- made maintenance a nightmare. We always used to say BSA stood for...

That jogged the memory a little- had a rummage in the cupboard- and sure enough, my HP35 and HP11C are still there. The 11C still turns on (batteries must be close to 30 years old now....) but no battery pack or psu for the '35 any more. So I had a bit of a play with the 11c- just enough to...

I'm pleased to report my XL has finally arrived! And it certainly hasn't disappointed me. I changed my order to the 5 head model, which delayed it somewhat, but it is now up & running in it's home-made enclosure. My first print (other than the test print) was a box for the tools that came with...

Bluejets, would you mind giving some references to the relevant australian legislation you spoke about?

If you can make those rule stick then I am very envious of you GreenTwin. Almost all the workshops I grew up in and around seemed to follow the rule "don't put it away, put it on the floor/bench/machine tool/anywhere but away" and after 75 years it's kinda hard to break the habit. I am trying...

I can really identify with the "Take Inventory" paragraph- I have extended my workshop no less than four times, to well over four times it's original area, each time finding the truth in the saying- more space does NOT equal more room- just more junk! Now if I could just find that new set of...

G'day Alan, welcome to the forum- always good to have a new member from one of Tassie's northern colonies......

ennech (post 17), you can get brass "heatset inserts" designed especially for this sort of job. For example- https://hackaday.com/2019/02/28/threading-3d-printed-parts-how-to-use-heat-set-inserts/

Taxing my memory somewhat, but I think I solved this problem with mine by using integer division, and more importantly, by doing each tooth calculation from scratch. Thus no accumulated error. But I am going back quite a few years now, so I could be remembering wrong.

Or the command (while in EDLIN) to low level format your hard drive- G=c800:5 Why do our brains remember these odd arcane snippets?

Nobody has mentioned vapour smoothing yet- a quick google search using "pla vapour smoothing" brings good results. It's a very good way of producing an excellent finish on 3d printed parts with minimal physical effort.

Richard, I found this when searching for a way to read the AD_PRT files- would you consider exporting them as step files- "To export an AD_PRT file as a STEP file, open the file in Alibre Design's part designer. Then, select Save as... and save the file as a STEP file. This will allow you to...
