So I thought I was relatively well read regarding my options for getting 3 phase into my workshop. I'm picking up a mill so with my lathe I think that makes 5 off 3 phase motors. I was thinking it would be best to go to a rotary phase convertor. Although they are a bit expensive and a bit noisy.

I've just bumped into digital phase convertors whilst online. They seem ideal so why are they not as popular as the VFD's?

Example I've been looking at

Thanks to everyone for your input. After reading some of your stories I've had another think. One of the local farmers has agreed to lift it off the trailer for me so I don't need to slide it down the ramp anymore!

OMG. That's fantastic but must have cost a fortune.

I have hired a bobtailed plant trailer. It has a full width ramp that's only 13 degrees. I intend to roll it down the ramp on the pallet truck controlled by a chain block.

Thanks for this. Ivece.ailed you.

Is the mill lacking in height?

That is the rolls Royce of solutions!! Thanks for sharing

I saw it as well. Just wished I had a fella with a HIAB

I am picking up a new (to me) Series 1 Bridgeport this weekend. Although the vendor can load for me, once I get it back I will need to move it with a pallet truck. To do this I'm going to bolt it to a custom made pallet. Given its shape I wondering if it would be most stable lifting it from the front, back or side? I intend to rotate the head down and perhaps position the table to try and balance it. Any advice would be appreciated

Thanks Colin

Thanks for this. I'm a complete novice and didn't realise the cutters would require different systems. Is it just the endmills that have the locking geometry. Is there an option to just use the Clarkson system and buy all the same type of cutter?

Every time I think I'm settling on something there seems to be a whole new level of detail. I really like the learning process but I was hoping to minimise the cost of it😀😀

Thanks everyone and as expected I don't think there is a definitive correct answer. It looks like the general consensus is collets make sense if you have the vertical space. For bigger stuff straight to the R8 collet.

This is one of these questions I'm sure must wind up the old and bold but after lots of searching I'm still very confused so stand by!!

After a short (30 year) break I'm saying myself back into machining. I've just picked myself up a bridgeport mill with a r8 spindle. So what next? Do I go for a er32 collet chuck or direct R8 collets?. I'm running a chipmaster lathe and I'm thinking it would be good to standardise my collets if possible. Would this be possible?

Thanks I made the same doert of spindle and mounted it in my 3 jaw. Worked well but I don't want to be polishing on my kathe for obvious reasons.

Thanks everyone, great advice as always. I would have never guessed it was one of the more dangerous evolutions!!

So I'm looking to convert my bench grinder to a polisher. I see you can buy tapered spindles that go onto the grinder spindle.

Are these any good?

Are they held on by the grub screw or do they screw on?

Is it possible to make on my lathe if I don't have a taper turning attachment?

Thanks

I've no idea what these are but they sound like an ideal project to make with the mill if I buy it!!

Thank you for all the replies. It looks like 1000rpm is going to be fine for me. I'm very happy with the idea that I just need to slow the feed rate to compensate as I do enjoy a cup if tea.

I'm looking to buy my first milling machine and have been considering a victoria elliot V1. It looks to be a robust machine. The top spindle speed is listed at 1000rpm. I'm looking to do mostly model engineering and bitsvand bobs for motorcycles and my land rover so I'm guessing at the smaller end of what this machine is capable of. Is this top speed going to be too slow for this type of work?

Buffer thanks for the input just what I needed.

I have the oppertunitybto buy a Tom Senior M1 milling machine. I think it's one of the earlier versions that does not have the oilvfilled gearbox feedingvthe table. Is this an issue. Is there anything else I should be looking out for when viewing?

Thanks Colin
