My mistake i meant marked as RST for a single phase vfd

Yes they are the same size

Is it a 400v inverter? Rather than a 200v one ..is it expecting 3 phase in? Some will run on 240v on 2 phases

That’s strange I’ve never seen a VFD where the input terminals are marked R,S,T usually they are L1,L2,L3 if 3 phase or L1,N if single

Many of the older startrite machines say s14,18,24 have 10 speeds with 5 belt positions and a 2 speed gearbox they will happily cut anything.

but I wouldn’t want to stand there cutting 5” of steel with it

i have a s14 5 and cut alloy plate regularly on it up to 3 inch thick

but mainly i use it for woodwork and a 4x6 bandsaw for metal stock

I would drill 2 small holes behind the bearings in the casting at centres of 28mm so a pin punch can knock them out together using the outer races

Steve I’m in awe at all that on 1/16” ss

Can you talk us through your mass production process and what tools fixtures you used?

And are galvanised bolts common in m18?

I was browsing eBay looking for a new tap and noticed a few 18mm x 1.5 taps with + 004” and + 0.24 after the size

i must confess i had not seen such before

why have an oversize tap?...only seemed to be for 18mm that I’ve seen

Once you have used a drilling machine with variable speed you would never go back to a belt change type.

I’d agree with thomas fit an inverter for about £100 all in you wouldn’t regret it

keep your original motor and go from there

Putting some figures into here seem to suggest about 13,500 $ which doesn’t seem bad so less than a $ per container

Has anyone any idea of the sort of charge to transit the Suez Canal? With 20,000 containers on it what sort of price for each? £5 makes it £100k. £50 makes it £1m

My BIL had a look and suggested imperial weights going down to drams which is why some of the fractions have + 2 (say)after them that figure is drams

I also bought one some years ago.. seem to remember it was only 80 or so

and just as you its excellent and is my everyday fitted chuck

One of the stainless birdsnest scourers works for me

My elf must be great big goblin

i’ve spent 2 hours looking for a 1-3/8ths” tap 5 inches long and best part of a kilo

had a break to look for a new one on eBay then went armed with a torch and there it was lurking under a rotary table

I’m sure that it looks ok your tailstock locates on the left hand “v”

Thank you split pin

I found in my large taps drawer and have being using this tap...

theres no markings on it but it measures 1 .31 “across the peaks and pitch is 11 tpi

so i can see that its a 1 5/16 11tpi and if i cut a 55 degree male part it screw perfectly into a hole tapped with this tap.

but what purpose would it have originally served

all my books don’t seem to have any taps of 1 5/16 diameter
