Thread: Laser cut items
16/08/2020 22:26:04

Thanks for the reply Robert the material in mind is "ordinary ? " mild steel, ... just frames for garden loco items for the grandsons. Seem to remember oxy acetylene/propane cutting gave a hard surface skin?

Evening all,

I have in mind to get some bogie frames laser cut in 6 mm thick material. I will need to bore holes for the 28 mm dia bearing. So will lasered holes at 27.5 mm be ok ? An extra thickening ring will be added for the bearing seat.

I am worried that you get a tough layer on the lasered cut ?

Thread: Painting on old galvanize

Mordant solution is the traditional treatment for galv but there are several modern primers that will work such as Zinsser's "Bullseye 1-2-3"

That is good stuff, makes paint stick better than "anything" to blanket !

Yes I also believe, from my Landrover days, that hammerite do a primer for galv and ali.

I few months ago I painted a double up a over door in a paint by "Bradite", quality stuff. I am no painter but it went on a treat, one coat of a light green over purple, no runs. Very optimistic that it will perform well. My paint brand of choice now.

........ "But firm enough to control a grab - my pillar drill is the most dangerous tool I own "

Made me smile, brought back memories of an old mate who tought me a lot, once said hold on Pete when I was out of order, I have seen a drilling machine make grown men cry. ....

Respect, even more for my big radial woodwork saw !

Sorry for the intrusion but we all need a smile these days

Thread: Turning wheels to the standard
01/08/2020 10:03:30

Thanks for the input both, the picture gets clearer. I like the roller idea Duncan.

I was expecting the drawing to be easier to follow. I can't remember having trouble reading a drawing before, but I have only been at it over 55 years?

Content apart I would have presented the drawing as a mirror image, as it would be made in the lathe?

I suppose this is a drawing of a left side wheel ?? !! lol

Solicitors should surely deserve a mention, making a simple job complicated and then charging £195 an hour, plus vat Gaaarrrrhhhhh, We perhaps need them sometimes but at a 25 % pay level.

Estate Agents, somehow also manage to make me challenge their worth and performance, or lack of it ? Forgot performance also applies to Solicitors who can't even be  be bothered to talk to you, once they have you on their hook.

lol to most of the posts.

Thread: Turning wheels to the standard
31/07/2020 10:23:42

Thank you for your help here SOD and all the people who replied to the link referred to.

Many good points made and I now have a way forward. I have been on Libracad and now know how far to machine in from the wheel face, at a distance in (5/32) from the wheel tip with a radius on the tool, then work on the taper until it "looks right"

All help really appreciated, I was trying to work from the standard drawing !

Still don't understand the radius on the tip being specified at 0.038? lol. I thought someone would know why and how to achieve it ?

I will go and make some wheels now I think..............

Hi all think I am having a senior moment. I have been staring at the GL 5 drawing for wheel profile and don't quite see how to work from it without a lot of fiddling ?

I see the measurement to establish the tread diameter, from the overall wheel size but no reference to where the inner radius starts?

I see the with of "width of flange" ? which gives you a point on the 20 degree incline , don't see the point of this?

What am I missing here please? I could draw it out to find the start of the inner radius, but shouldn't be necessary

What is the significance of the tip radius i.e. 0.038?

Am I over thinking this?

Thread: CAD for a Chromebook
30/06/2020 08:28:37

I have solved it, after much searching. smiley.......Librecad , a spin off from Qcad.

Simply installed with " sudo apt install librecad " in the terminal window. Like all linux apps that I have tried on my chromebook seems to work well and icons appear on the menu screen. Very pleased with it all.

Thread: Free or inexpensive 2D cad for clock wheels

I have used Qcad for years, Linux but there is a Windozz version and been very happy. I am now searching for something that works on a chromebook ?

Thread: CAD for a Chromebook
25/06/2020 15:52:18

Fusion 360 hobbyist is not compatible with the Chromebook, sadly. Think I shall have to investigate installing sssssss

qcad, if nothing else turns up ?

16/06/2020 09:59:52

Not heard of Mrchromebox, will check it out. Still with the chrome os, which I have not had a problem with, time will tell. I added some linux stuff but dont see a need for it? Qcad was my only issue to date, fusion should solve that I think?

I have been with Linux in various forms for over 15 years, a bit of work needed in early years, but Mint is now well sorted. Reason for Chromebook, were quick boot time and battery life and a dodgy keyboard on my aged laptop.

At the back of my mind was a security issue, which probably doesn't exist, may be not solve by opting from the chromebook ? Sold my soul to Google.

Pete

Thanks for the reply, looked at Fusion and note that a free subscription for one year is mentioned, is this renewable I presume?

07/06/2020 12:49:36

Well I bit the bullet and bought a chromebook, very pleased I am with it, linux activated as well. Am I right in thinking Autocad for android is now free? Can't quite believe it but seems the obvioous choice to me?

Any ideas

Thread: Old Computers - why do people bother

I think I keep my old computers for many of the same reasons that I keep my old wife. I've got to understand their ways (to a limited extent), they still work, my requirements are much as before, and newer models tend to be expensive...

Plus one, spot on!!

Linux for 16 years, over half of it with Mint.

Thread: Hoist Frame
30/01/2020 12:50:43

I eventually decided on a different route for moving the vertical head of my 1ES, weighing in at 42 kg.

No picture to hand, but I basically welded up some 25 mm box section to form a bridge cradle with support feet by which the head could be lifted a few mm. via a bolt. I place a board on the table, remove the head and then lower the table to the same height as the bench where the head lives. The cradle and head are then slid along the board onto the bench.

The original idea was to have a length of track on the board and rollers on the cradle feet, but I needed to mount the head in a hurry, so never got round to that bit.laugh

Bit of fiddling but a cheap solution that works for me.smiley

Have a look on the Parkside Electronics web site, lots of info on motor size and gearing that may help. Lots of useful stuff there.

Than you both for the information, food for further thought.smiley

One thing for sure, Windoz went out the Windows here 16 years ago and won't be coming back.

I have been a happy with Qcad via Linux for a long time but now I am looking at Chromebooks. I hear that Linux can be dual booted so perhaps not a problem, but is there prefered, !!!?? drawing app for the Chomebook for simple drawings?

Might get into 3d printing one day?

With Thanks

Pete
