|Thread: For discussing the merits of alternative 3D CAD programs.|
Thanks Eddie, that was very clear and interesting. I've never seen Rail-revolve before.
Thank you Eddie, that was much clearer. Did you drill the centre before or after turning the profile? If after, how did you hold it?
Without any form of commentary, it was more like a conjurer pulling rabbits from a hat.
|Thread: Fitting an adjustable damper to my power saw|
|Thread: Understanding plans.|
Center line shown, but no hidden lines.
Unfortunately, whilst your example shows a 3rd angle drawing, the projection symbol (the little cone) depicts 1st angle. Or am I confused?
|Thread: Twin Tube HF fluorescent lighting for the workshop|
I replaced the 3 twin 6ft fluorescent tubes (not HF) in my workshop with LEDs. My old eyes cannot detect any flickering or strobe effects. The LEDs are far better with a cleaner, purer, light. And instant on/off.
|Thread: Introducing Arduino|
Hmm, it worked OK with my free version of PDFill PDF Tools 9.0
|Thread: What bearings for a submersible wheelchair?|
I suggest you read my post timed at 10:03:23
Hi Ian, I know such wheelchairs are available in NZ, Australia, and the USA, but apparently not here in UK.
Thanks for all the good advice. Here's the background to my requirements.
I do voluntary work for the Remap charity (the church-door handrail shown in last month's MEW was one of mine) and neither the swimming club nor the charity can afford to spend much. The hydraulic lift consists of a large platform, level with the side of the pool, which can be lowered into the pool. The wheelchair must be of conventional design so that people with sufficient upper-body strength can propel it themselves. The frame of the wheelchair will be made of PVC pipe and the wheels and casters I have obtained are plastic, but they have conventional steel bearings. There are 12 bearings in all, of three different sizes. Since cost is a major consideration I thought that machining them from solid would be the most cost-effective solution. Delrin or PTFE seem the way to go, but if I could get some lignum vitae at a suitable price....
I have to make a wheelchair to transfer disabled people from the changing rooms to a lift that lowers them, wheelchair and all, into a chlorinated swimming pool. And getrs them out again.
The real problem is the wheel and caster bearings. Ordinary steel bearings will simply rust, so what bearings should I use. I'm thinking of solid bearings of, say, plastic, brass, or bronze. Nylon is probably unsuitable because it absorbs water, but what about Delrin? It's only about 50mtrs from the changing rooms to the pool. What do the experts recommend?
Do stainless bearings exist?
Another way of looking at it is...it's rather like a vertical mill: X-axis (red) goes left to right, Y-axis (green) goes away from you, and Z-axis (blue) goes up and down.
Like I said in my post, Z-axis is blue
X-axis is red
Y-axis is green
In Fusion, the Z-axis is coloured blue, X is red, and Y is green.

Are the parameters locked even though the L2A parameter shown on page 56 is set to Yes?
|Thread: Problems with a breadmaker|
I don't think the machine has more than one heater.
Somebody advised her to store the yeast in the fridge in an attempt to solve the problems I've mentioned, but it had no effect.
She uses only Carr's flour purchased in 1.5Kg bags, and weighs 10oz of wholemeal and 4oz of strong white per loaf, which she makes every two days. She typically has one opened bag with one unopened in reserve, and always checks that the water is at approx the same tepid temperature every time. There is no heating in the kitchen but there is a doorway (without a door) to a heated room.So the kitchen temperature does vary, but, because it's an old Victorian house it takes a while to respond to the external temperature.
My wife has been using a Panasonic bread-maker for many years. She always uses the same recipe, brand of flour, and yeast, but the results vary. Mostly the bread rises OK, but has a distinct slope, with one end taller than the other. Once in a while she gets a pretty near perfect loaf, and occasionally it hardly rises at all.
We've been unable to figure out why the variation and, in particular, why it sometimes hardly rises at all.
She uses the same brand dried yeast and stores the opened packets in the fridge.
|Thread: Cycle chain drawing|
In TurboCAD there is a "Circle tan to Entities" command.
The attached was done by...
1. Draw a 12.7x2.25 rectangle
2. Draw two 8.5 diam circles with centres at the lower two corners of the rectangle
3. Draw a Circle tan to entities circle and choose the the two circles and the rectangle.
|Thread: What do you call this type of chuck?|
Thanks guys. The expense and size puts them out of reach for my requirements. Even if I could afford one it would need to have a capacity of up to 75mm. I'll have to stick with making individual holders.
