Thread: Tool post height
07/07/2021 10:30:08

I have both an original Myford 4 way tool post and a Myford QCTP set up. The QCTP gets more use because I am lazy, but the 4 way tool holder is appreciably more rigid and gets used on the more difficult jobs.

Thread: Anyone know what is going on at Homeworkshop?

Went to the homeworkshop site and found for the first time ever, that I needed to log in. There was also a very weird message on display.

Thread: Tracy Tools.

Chris, on reflection, maybe you are correct! I could have had a relaxing weekend if the taps had arrived on Monday!

Andrew.

I ordered a set of taps yesterday (Friday) at 3.00 pm. Arrived this morning (Saturday) at 10.am.

Well done Tracy Tools and Royal Mail. Got me out of a hole!

Hello Swarf Maker,

My comment wasn't about you. Apologies if I my post offended you, it was intended for someone else entirely.

The trouble is that you have to read a post before you know it contains B/S. I have used the ignore button so won't be afflicted again.

Thread: Another dirty Brian trick - reversing the chuck
25/06/2021 21:06:53

!3 amp fuses, as in plug tops are not quick blow. They will also pass a tad more than 13 amps on a steady basis, without blowing. Did some real world tests to check this, so don't throw specifications at me!

Thread: Can I use a NiCD Battery charger on a NiMH battery?
24/06/2021 10:02:40

NiCd batteries are still widely available. Batteriesplus have tagged 2400 ma NiCds for just over £2 each for 10 (gives you 12 volts.) The snag with NiMh batteries is that they have less current output than NiCds so they are not ideal for things like battery drills. You will get less torque with NiMh batteries.

As far as charging NiMh batteries with a NiCd charger, it will work, but take a much longer charging time.

Thread: Help required for brain fade!
23/06/2021 18:45:06

Thanks Diogenes! I simply could not remember the correct name!

Regards,

Andrew.

23/06/2021 18:38:04

I am trying to think of the name for the following item. Short piece of round rod with a shoulder at one end and a cross drilled hole at the other. The hole usually takes a split pin and retains a washer on the rod.

They are widely used to fix parts together. I have some aluminium ones on my Bergen rucksack, holding webbing to frame.

I simply can't remember what these fixings are called, help please!

Thread: What V belt cross section for use on a standard sized Picador pulley
16/06/2021 18:42:50

Hello Bob, that is interesting I now have an A section belt running happily on the 2" pulley, Maybe working well because I have used a notched pulley which bend more easily.

Where did you find the 3" minimum diameter? Please don't say Kempes handbook!!!!

Thanks ,

Andrew.

Thread: Cosmos 1.5 HP micro compressor.
16/06/2021 13:01:33

You need to take up the term "Micro compressor" with Cosmos. Their description, not mine. It is rated at 120 psi has a 20 litre tank and a 1.5 Kw motor.

Thanks for that information Clive, it makes sense to me. The compressor unit is sealed (quote from blurb on the tank) and according to the same blurb on the tank it is " oil less". Despite the claim that it is a sealed unit, there appear to be enough bolts on show to strip it down!

Thanks gentlemen.

Andrew.

I have come by one of the above compressors, which are of Italian manufacture. It came without a pressure regulator on the output, which isn't too surprising, what does surprise me is that there is no pressure switch and no sign of one ever being fitted from new.

I am not a compressor expert, is this normal for a small compressor?

Thread: DC power supply question
15/06/2021 15:15:41

The normal way of securing a toroidal transformer is through the hole in the middle of the toroid, so may not be a good place. Also the transformer generates heat which isn't the best thing in the world for an electrolytic capacitor.

Otherwise go ahead and put the capacitor there, it isn't going to matter a great deal and there is no "electronic" reason why not.

Just be careful when securing the toroidal transformer that you don't create a "shorted turn" . Easy to do if you are not aware of this potential problem. It won't do the transformer any good at all!

Thread: Etching Aluminium
13/06/2021 11:21:27

For what it is worth, most etch primers for aluminium contain phosphoric acid as the active ingredient. Being a cheapskate I usually prime aluminium with phosphoric acid and then just paint with any old paint. It seems to work well as the oldest aluminium to have had this treatment is 30 years old now, with no sign of peeling.

Hammer and drift is all you need to remove and insert valve guides, I must have done a hundred or more over the years,

As for advertising even your approximate location on the net. I don't think that is very smart with all the rogues around. That is partly why we have a PM system..

Thread: What V belt cross section for use on a standard sized Picador pulley

Hello Dave,

Not difficult to chat to my GP as he is a neighbour!

Thread: Best choice of material
10/06/2021 17:34:52

I think it depends on the lathe. I refurbished a 920 lathe for a disabled friend. The design is poor and there is a lot of potential tool movement because of an inadequate base. Even doing one of the standard mods to overcome this, still doesn't give a really firm tool. I took off the topslide and made a "Gibralter" tool mount. That made a huge difference. You can still remove this and reinstate the topslide for the odd time it is needed,

Maybe your lathe is sturdier than the 920, but even so your idea is to be recommended. I very rarely have need to use the topslide anyway.

Andrew,

Thread: What V belt cross section for use on a standard sized Picador pulley
10/06/2021 17:24:31

Thanks everyone,

Looks as though it is indeed an "A" size. I even had Kempes yearbook in front of me when I typed out the query. As for Mark's comment about being any size, I seriously doubt this. I must have seen a few hundred Picador pulleys over the years and they have all been the same belt size. I think that Swarf Mostly is correct in saying other sizes were branded Pelican.

Anyway all is sorted and I checked an "A" belt on the pulley and it is the correct fit. I don't think I was too good this morning, otherwise I would never have asked such a question. Maybe I should have a chat with my GP.

Thanks everyone,

Andrew.

Having a case of brain fade today. I have a 2" Picador pulley, for which I need a V belt. Cannot for the life of me find this simple info!

I seem to remember that the belts are an "A "cross section, is this correct?

Thanks,

Andrew.
