Thread: How much ?

Posted by Bazyle on 04/04/2015 18:28:

Not so sure about things in a 99p show costing 99 pennies. Don't they cost 240 pennies with 1p back. Can't be bothered to calculate how many actual pennies that is.

Really Bazyle,

This is absolutely intolerable. wink

Hello Paul,

I don't know if this would suit your purposes, but it's a good method to know anyway...and it works!

Best regards,

Thread: Toolpost grinder tips?
26/02/2015 21:36:29

Hello Scott,

The first thing to do is lose a nought off the lathe spindle speed. 250 RPM would be a much more realistic work speed for grinding something that diameter.

Best regards,

Steve.

Mine arrived this morning. Very pleased following a quick look. A great deal of info for your pound/dollar etc

I was lucky enough to drive a 15F a few times at Vereeniging depot in 1988, so these will make good reading and remind me of great days.

Thread: No. of divisions

Hello,

The sleeve gear is 31T 40DP as is the other bronze gear. The steel gears (including the centre shaft) are 29T 40DP. The 29T steel gears are 0.775" dia and the bronze gears are 0.825" dia.

Hope this helps,

Best regards,

Steve.

Thread: Stepper Driver Help needed please
28/10/2014 08:48:19

Hello Les,

These are the terms that were placed on the eBay listing. "Returns: 14 days refund. Buyer pays return postage". Not sure how this relates to a faulty component but I think I'm on a bit of a sticky wicket anyway, as this was purchased 2nd September. I have only just got around to fitting it. In hindsight, I should have tried it when it first arrived.

I'm not sure that the output would be at mains potential. The motor is rated at 5.86V DC. I've been running the driver at 110V ac from a site transformer. I made this decision because the 220 volt limit made me think that UK mains voltage might be slightly too much.

Steve.

Thanks Les,

I'll try to take some photos tomorrow but I don't know how good they will be.

Hello all,

I have been working on a CNC conversion for my Bridgeport Mill. The original idea was to just motorise the X axis and a 6” dia HV table so that the machine could cut gears whilst I got on with more mundane tasks.

The rotary table was done first with a NEMA 23 motor from Arc Euro and a cheap single axis TB6560 driver. BTW, I have found this driver absolutely fine for the NEMA 23 motor, despite hearing and reading many things to the contrary.

The X axis was the next to be undertaken using a Nema 42 motor and a DM2722A driver from Longs motors, again based in China. This was completed successfully and runs very well when driven with Mach3. For the gear cutting, I can live with the backlash on the X axis, but there are hopefully some ball-screws being brought into the UK for me next month.

Work has progressed on the Y axis conversion and I was all set last Friday to run both axis at once and cut a circle, albeit in fresh air. Unfortunately, the Y axis driver has shown an alarm from initial power up and refuses to work. I swapped the drivers over so that the “older” driver drove the Y axis and the motor was fine.

 

I have contacted the suppliers in China and they pretty much say that I must return the driver to them for testing, despite all my explanations and photos. I feel that they have me over a barrel really and the cost of posting to China and accompanying delays, doesn’t help my situation.

 

Is it going to be a practical proposition to have this driver repaired and is there anyone on this forum that could undertake such a task? I feel so frustrated because I came so close, even though I can still cut the gears ok.

Best regards,

Steve.

Thread: Myford lathe paint code.
28/05/2014 16:49:28

Thanks Mike,

This was for one of my customers in Germany. I suspect that he can have some mixed a lot cheaper than Myford's prices and also wouldn't have the carriage costs.

Best regards,

Steve.

Hello all,
