MT2 x 1″ arbor question

[Mexican jonParticipant @mexicanjon]

I'm trying to source a longish MT2 x 1" arbor to use with my myford (mainly for gear cutting)

Most of what i see advertised are stub arbors.

My way of thinking, rightly or wrongly would be that a longer arbor supported at the tail stock by a live centre would be better.

So i guess my question is? am i right in my thinking and does anyone know where i can purchase a long arbor.

Myford don't seem to do them anymore even throuigh all the archive pictures i see of myfords using the myford dividing head seem to have a long arbor.

There is nothing to stop you buying the longest you can get, boring the end and loctiting a suitable extension, or even brazing it, The ends are soft anyway.

Hi There

I think the only long arbor Myford sold was a between centres one.

Not ideal for milling between centres.

I would want a long 2 Morse taper one as used on a Centec mill or similar.

I think I would buy an Arc Euro Trade 2 Morse taper arbor with say a 16mm hole for cutters and make my own arbor from a piece of steel bar. Sounds like a good project for an MEW article. Any takers?

regards David

Jon,

Arrand make them, though I think you might take fright at the price (£140+).

They do make good quality stuff though.

Alternatively, if economy is your main driver, you could try making your own 2MT shank on a long piece of steel and then make the arbour you need on it.

Why not just run centres both ends.

[Richard MarksParticipant @richardmarks80868]

How about getting hold of a cheap MT2 test bar and using it as a basis for your project, I would imagine it would be machineable, RGD and Chronos do them, It would be worth a try.

Jon,

http://www.tools4cheap.net sell exactly what your looking for including the spacers for positioning the cutting tool. These are brand new reproductions of what the Atlas horizontal mill use. Jeff Beck is the owner and an excellent person to deal with.

How much!

Seriously though why not turn an MT2 taper on a bit of 1" bar and make your own arbour?

£19.50 for a properly made arbor – how long would it take to make and how much would the materials cost? Just how little is your time worth? As John says pay the money and get on with the job that really needs doing.

Exactly, there is a minimum charge of £35 over at the heat treatment shop over the road and God knows what them robbing bastards at Rolls Royce want to cylindrical grind it after heat treat.

 

It's all relative , I wouldn't give more than £20 for a toy choo choo anyway.

Oh once again toys being thrown out of the pram including a toy choo choo

Boys go purchase the tool and get back to work.

Getting back to the original posting.

Mexican Jon wondered whether a long arbor supported by the tailstock would be better than a short version. I would say that it depends on how near the MT2 end the load is. I say 'load' because we dont know whether its the gear or the cutter on the arbor.

Surely having the cutter or gear close to the headstock is going to more rigid than the same load in the middle of a long arbor with one end only supported by the tailstock.

Oops

Never thought this would get of hand !!

All I was asking or thinking was that if I had a long MT2 arbor which was supported by the tail stock (considering this will be a set up on a myford with a myford dividing head, cutter held on the arbor)sorry if i didn't mention this before)) that is would be more versatile and better than a stub arbor. As for marking one, yes i agree it would be nice to make my own but as others have said would it be economical. Any ways sorry if I caused an argument I was just looking for opinions to whether my way of thinking was right wrong or indifferent.

Hi Mex

Well one of the features of this forum is that it does tend to get a little out of hand at times!

If my remarks fall into that category then I apologise – it was not my intention that they should do so and I guess I was reacting to other posts rather than to your original query. Looking at the 'photo of John's suggested arbour from ARC I wonder if it has a centre hole at the nut end – if so, you could then of course, provide additional  tailstock support. A call to them on Monday would, I'm sure, supply the answer.

Regards

Norman

[John Stevenson 1Participant @johnstevenson1]

Yes it does, i often run one with a centre support for rigidity.

One of the first things I made on my new lathe when I gave up wood turning was a batch of morse taper centers for wood turning, about 10 pairs of driving and tailstock centers in size 1MT, and 2MT, that got me cutting tapers fairly well, maybe not too fast though, but they sold well. Made a few simple live centers, suitable for use in a wood lathe. Ian S C
