|Thread: mini grinders|
I have gone through two Dremel grinders and a cheapo lookalike in three years. The Dremels failed due to speed control burning out and the motor burning out on the second. The cheapo gearbox fell to bits.
I don't use them heavily and only occasionally. Thought I'd treat myself to a Proxon, read a lot of very good reviews, not seen a bad one.
Having got one and used it for light sanding it suffers the problem of over heat. Gets very hot very quickly. Too hot to hold in a matter of minutes. Don't know how long this one will last. I've come to the conclusion that there isn't a good make out there.
Thank you for the replies. I would like to sandblast, ( maybe I should say grit blast), rust and old paint from small bits and pieces occasionally. I don't want to buy a new compressor, not so much the cost but a lack of space, the present one just squeezes in.
Looks like I'l have to stick to a wire brush!
Does anyone know if I could get away with running a sand blasting cabinet on a 9 cfm 50 litre compressor?
|Thread: Socket set sizes|
Looking at them again I think they're probably AF. I have a mixed set with some missing. Think a previous owner must have used the box for a lot of loose sockets he had! I have BSW, metric and AF in one box.
I have some sockets that were given to me. I thought they were AF sizes but they're not. The 7/16" fits a 1/4" whitworth nut. (This is the only nut size I have that fits one of the sockets). I cannot find any charts that gives 1/4"Whit = 7/16" something. Any Ideas?
|Thread: Myford ML7|
I have a Myford ML7 lathe. It’s week point, imho, is the bushes with drip feed oil.
|Thread: Need advice on clearing Dads shed|
A local or even not too far away club may sill be a better bet than clearance firm. You may not get as much as selling individually over time but any clearance firm will give you far less than the actual value.
Search on line for model engineering clubs.
|Thread: Motor size|
I'm shortly going to upgrade the motor on my Myford ML7 lathe, probably NewtonTesla.
Question is: half horse power or one horse power? Anyone gone for half and wished they'd gone for more or gone for one and found it too big?
|Thread: Cheap stuff|
I’ve gone through three Dremel mini drills in two years, not used a lot either. Top money for junk.
|Thread: Acme or not?|
I’m restoring an old vice. The screw looks like an Acme in all respects. Problem is I can’t find it in tables. It’s 7tpi x 0.54 inch diameter.
Tables go from 6 tpi to 8 tpi, no 7.
I need to make a new spindle and have no idea what change gears to use on the lathe. Anyone come across this thread before? It’s Swiss made BTW.
The workshop is draught proof but built of heavy duty blocks. Another project this year is to clad the outside with treated shiplap, there goes £1000 +.
I have a dehumidifier but it stops working below 5 degrees. I could get a desiccant type but the running cost would be too high.
I heat with a fan heater when I'm using the shop. I used to use a convector with a thermostat permanently on but the electricity use was far too high. The cold itself isn't a great problem but when I do heat the shop even small metal things are so cold that they get wet through condensate pretty rapidly. I've lost a digital caliper set through the electronics getting wet.
Like the light bulb idea but don't think incandescent lamps are sold now....
My workshop gets very cold in winter so when I heat it during use anything metal gets wet through condensation. It would cost a small fortune to keep it heated 24/7 so i'm thinking of building a heated cupboard for precision tools.
Has anyone tried this? I figure a small thermostatically controlled heater would be off most of the time the cupboard was shut.
A dial indicator has a greater range than a DTI. More suited to truing stock in a lathe.A DTI has a range of typically 0 - 0.8mm in both directions whereas a Dial Indicator has a typical range of 0 - 10mm.
|Thread: Finding things|
A good tip for finding that elusive item:
Look for something else. Over many years I have found many things that were previously lost when I looked for something else. Never fails!
I'm looking to buy a new dial indicator. I've seen a Neotek 0-20 mm on Amazon priced at £42.99 including stand.The reviews seem to be for the digital version though.
Has anyone got any experience of Neotek stuff?
Maybe you could recommend a decent indicator, (not DTI).
My budget is in the £40 to £60 range.
|Thread: Newton Tesla Motor units|
Thanks for replies. I don’t need exact speeds, this is why I thought maths would work. Looking at the various replies I think I’ll go for measurements with my hand held tachometer and print a scale for the control. First job, order new motor.
A rev counter sounds good but fixing places on a Myford ML7 is limited. That’s why I was hoping to to use maths.
If you have a Newton Tesla Speed controlled motor on your lathe can you tell me if the RPM read out on the unit is directly proportional to the machine speed?
What I am thinking hear is, can I use a formula to work out the actual vs. displayed rpm or do I need to fit a rev counter on my lathe?
|Thread: Propane torch|
Can anyone recommend a decent propane torch for silver soldering please?
What's the best size of nozzle?
I'm looking for something that will fit on a standard tank of propane gas. Not necessarily cheap, would rather pay more and get a good quality piece of kit but that doesn't mean spending extra to look pretty!
