Thread: This looks an interesting small milling machine
16/02/2020 23:54:16

That looks a real good buy. I sold mine in about 1998 for 450 and itdidnt have all the mods that this one has. It’s a sound machine, but I switched mine for a rishton and swapped that for a Bridgeport n a small cnc miller table is small but adequate . The kits were sold part npmachimed, with all the big work done, leaving the builder to do all the small stuff. Totally superseded these days by the likes of sieg burpt in its day it was fantastidpc.. a good specimen. Go for it.

For the labels google water slide decals. You print the artwork onto a special paper. This is then varnished with two coat car top spray varnish from Halfords. Soak in water and the decal will slide off and you gently manoeuvre it into position and gently firm down. Finally spray varnish to seal the lot. It’s very straightforward but practise on scrap first. I tried to see what happened without the spray on the decal, when soaked, it disintegrated to mush. The paper is very cheap compared to what you use!

it gives truly excellent results

dacosta, , I suggested earlier that turning top hat type buttons  which can go through drilled holes will work so they won’t pop out.  Phil indicated the spring on the led board buttons will be sufficient to return it, but obviously you will need to check the sizes with care.  Use plastic if possible, you don’t want any conduction from damp fingers.

My sis lives in Auckland is so bad that it’s affecting her there in New Zealand , 2000 or so miles away. The sky is orange and stinks of smoke..

Thread: Timesaver lapping compound quandary

Bryan and Paul K . What grade did you use?

 

i will contact the sellers, but if people have actually used it on our situation the advice here is much better from the end user thanks for the link great help!  It’s packed with loads of info and it will take some digesting!

Paul L. , I have also used valve grinding compound on the cam operated stainless on bronze inlet valve seats ( there’s no exhaust in a uniflow) . I wasn’t happy with the possibility of embedding the abrasive which does not degrade in the same way as timesaver. In this position it’s actually directly in the cylinder., in any case I have no idea what the actual garage the “fine” and “coarse” is!

So has nobody used this stuff? Common fellers, give me some advice.....

but I suspect a drippy joint on the interface board

? Drippy? I typed dry But it won’t let me edit!

30/12/2019 17:21:45

Doubtful . It may work if you have the same 4 connections, but the ti software from clough42 is specific to the led n key board . My led n key board came in two days so why risk it?

have you got the stepper turning? Still working on mine, but I suspect a drippy joint on the interface board. I’m going to check the ti board with a led conjecture to the gpio

29/12/2019 09:37:35

That’s exactly what I used to wire it up.

29/12/2019 09:34:55

I think he mentioned removing the //. And adding it to another line So that depends on your own setup. I didn’t have time to fiddle yesterday so that’s the task for today! anything is worth a try. Thanks Phil.

29/12/2019 09:21:18

Thanks Phi I think there’s a mention about this in the software loading video, l I’ll check that later but I used all the same connections as I did from the arduino which worked a while back , I think I’m common 5 v so by rechecking with the arduino I’ll be able to measure the voltages

by the way, the display connector pins projection under the board fouls and shorts onto one of the small jumpers on the ti board if it’s pushed fully home So don’t push it in. I’ll add some insulation here. This stopped the display working , interestingly, clough42’s board is inverted compared to ours with the power socket where our display connector is.

28/12/2019 23:41:11

Got mine assembled n tested yesterday, did the ti board today.

Removing the switch covers was a nightmare!

All works with encoder in the drill giving correct rpm , but as yet I can’t get the stepper turning. No scope to see what’s happening at the outputs. I’ll have to check n recheck as well as checking stepper system with the arduino

so when it’s turning slowly I can then try voltages on the output pins with an analog meter , my digital is too slow and prob remove the micro steps in the ti settings fir a slower step n longer pulse. Then I’d be stumped

Mine arrived a week ago, dispatched on dec3. That was quicker than expected!

Thread: Is COMPAC' DIAL GAUGE METRIC TYPE 532 60mm Dia worth 45?
22/12/2019 10:48:31

That’s it! Get a lever type since getting mine I use the plunger one only once a decade!. They are far more versatile, aided by their compact size and ability to move the lever to convenient positions. You can’t use a plunger type to work in a bore without inconvenient add on parts thus, turning it into a lever type!

Thread: Scam alert
20/12/2019 17:20:59

Two points

1) recent tv program where the presenter got a phone number in seconds (via a net specialist) of a journalist who specialised in anti scam information. He was sent a text supposedly from Amazon saying they would ring in 20 mins which the presenter did, then asked the usual security details but stopped this half way through when he came clean. The victim was amazed he had been trapped so easily and it could have cost him a lot if it had been a scammer

2) our phone is on permanent answer phone.. scammers usually hang up when they hear “ Sorry, we are not at home” Most after the first word. Al” our friends know this and speak, and we pick up

Another thought for the web designer is to include a 'Preview' button if possible.

 

 

Just found this thread and I wholeheartedly agree with this, a preview would remove the frequent edit info.

edit.     Just like this one like a number of mine for typos or silly auto fill

Thread: Myford Super 7b lead screw end float
16/12/2019 23:09:41

I don’t think it’s really important as you only drive the saddle in one direction at a time so any backlash is catered for each time you change the direction it’s being moved. It is of course consistent in value. As ega says, adjust the nylock nut in any case

Thread: Build a watchmakers lathe
15/12/2019 00:18:08

I agree with John about the possible problems with the er collet not running true, but perhaps an enquiry to a watchmaking forum would be a good idea. I believe most lathes use a draw in collet system which will not need anything like the force to close compared with an er collet. The disadvantage though is that they will only hold a single size of stock.

I think you are planning to make this for its own sake rather than using it as a working machine tool. Is that the case?

Here is the information from Tony Jeffree regarding stepper motors referred to in his cnc conversion. I have photographed and erased unrelated parts and numbers the images. It is part of a series he produced about converting a Taig mill to cnc in MEW Dec. 2006 I have discussed with Neil about presenting this info.

He deals with basic info and information simple methods how to assess the torque amp drive select stepper motors

I’m not posting the info here, but you can view it in my album called ..... Leadscrew.......

Servo or stepper?

Regarding blowlamp and his valuable info regarding servo motors, he I think is spot on with regard to full cnc esp on the cross slide fir maintaining accurate diameters. I do not think this is so important for the leadscrew alone. Time will tell. I have spare steppers, and driver systems and I will test them out first and replace with a servo if there seems to be a problem

Thread: Timesaver lapping compound quandary
12/12/2019 18:18:22

It was difficult enough to get all the bores and 45 degree seats concentric in the first place, I think the only way to lap them is how we used to grind car engine valves, ie one pare against the other. This is why I want to use Timesaver, as it’s non- embedding and it wears down to nothing. Separate laps for these components would be very difficult to make and get a fit. But thanks.
