Yes. Great on brass before soldering for example and all sorts of other polishing jobs

A mill cant make a mill because how do you make the spindles and circular bits with a mill?

Yes it can, use your imagination! smile

A horizontal mill can be used to turn short, large diameter parts that would otherwise be too large. See here:



I had seen something like that in ME but I'd like to see you make a leadscrew on a mill dont know

Surely a lathe could make a lathe if you don't include making the bed as that could be cast then scraped.

Thread: Mounting an ER collet chuck
29/06/2019 17:15:15

Well armed with all your advice I went out and cut a register that was just a little tight and a little shallower than the recess in the chuck. I then pulled it up onto the bolting face using the bolts. With a Verdict indicator on the internal taper it moves with the slightest sway about 0.0002 inch. If anyone is interested the chuck came from Arc and the camlock backplate from Rotagrip.

Thanks to all of you who gave advice.

Are these registers definitely the way to get the best concentric fit? Is that how they are made? Is it a ridiculous idea to just nip it up and then gently tap it across in a similar way to moving something onto centre in a four jaw chuck.

HI when mounting this er collet chuck onto a backplate. Should the register be cut deep so the chuck mounts with the central lower face in contact with the backplate. Or shallow so the bolting outer face contacts the backplate. Or maybe it doesn't matter.

Thanks Rich


Thread: Making leaf spring buckles

Colin I folded my loco buckles and then soldered the end in. If you mill them from solid leave it attached to the bar as it makes it easier to hold when your filling.

Thread: Do you clean your workshop at the end of the day?
28/06/2019 18:07:06

I clean and put away on the days I'm too tired after work and can't be bothered to try and make bits.

They had a word for that, the preponderance of ths gun, obsolete now when they don't have trunions

Thread: Threading Problems on Colchester Student
18/06/2019 01:46:00

I found a new way to mess up work once. I was engaging the power feed and not the half nuts. I was so angry at not knowing why it wouldn't work I gave up trying to cut a thread in the lathe for about 5 years.

Thread: Hardening a form tool made from Gauge Plate
15/06/2019 11:05:02

I have just had a success by heating it to carrot colour then quenching in brine. Perhaps it was cooling to slowly in the oil. As advised I also didn't temper it I just took it easy and it works well.

Anyway thanks to all of you who offered advice. I can now make accurate form tools that work.smiley

Regards Rich

Jim it was bought off an ebay seller who says it meets bs specs but that's as much as I know. I have no other way to.telll if it's of a good quality.

Think I'll just get it real hot and try it without tempering. I have used it on brass so even if it doesnt harden enough it's not totally useless.

Thanks rich

14/06/2019 18:52:27

Om so I will quench in brine and ias I cant accurately gauge the temp is it worth just giving it full blast with the gas. Can it get too hot? Or am I likely to just be wasting gas.

Thanks rich

I have just had two failed attempts to harden a form tool made from a piece of steel sold as Gauge Plate 01 20x8mm. Its being made to cut mild steel and I heated it to red heat for 10mins then quenched in engine oil. I tempered the first at 230 C (Peter Wright Model Engineering Foundation Course) in the oven then the second at 190 C (Tubal Cain Hardening &Tempering). Both were not hard enough to cut the mild steel on the lathe.

Does anyone know if its likely that I just didn't get it hot enough? The time seems about right to me for 8mm thickness.

If its not hot enough would it be ok to just blast it with the burner to get it much hotter or do I need to try and be more accurate with the temperature.

Any advice would be much appreciated.

Regards Rich

Thread: Ballscrews?

If your not using it for CNC and you have made no calculations of load you might as well not worry about good or bad ones. Just get a big one and hope no bits of your little pink body are near it.
