Made myself a motor cycle lift to save my aching back. It's not quite finished but not much to do.

Can get all them little jobs done now!

Hi Martin

I fitted the ARC after market gib strips to my 20 year Chester mini lathe. They improved the feel of the cross slide but I was still getting problems which I put down to the gib strips rotating (original ones did to). I do hammer my lathe. To try an improve things I shimmed up the gib strip to try and prevent this and to a point it has worked. If I get a dig in I can still see the tool post move. I just used some shim strip I had around. My thoughts on this are because the adjustment screws now touch lower on the gib stip it is harder for it to try and rotate.

Repaired the top bearing on my Bultaco 250T by fitting a sleeve bearing. The shaft runs directly in the aluminium which had worn considerably. The shaft itself has worn but when I put it all together it's not bad. I did buy materials to repair the shaft but the work involved to remove a few thou' play didn't seem worth the effort plus I realised I made a mistake in my measuring so could have ended up with a locked up shaft.

Hi Andy

Don't overtighten the draw bar, I have heard of tales of woe when some MT's won't release.

I think it is finger tight plus 1/4 of a turn. I use R8 on my mill so not over familiar with the exact torque.

Cheers Michael.

Hi Ed

Do a build thread. (please)

Draw up a spec before you start to build, you've not mentioned a feed override button, wish I had one.

I went the route Emgee mentioned. (switch points in direction of travel).

The no vault switch can be made with a double pole relay, when it powers up a set of contacts keep the relay energised. When power is lost the relay drops out.

Have fun!

Cheers Mike.

Thanks Muzzer and Nick

Probably stick them on Ebay on the next clear out.

The arc welder has aluminium wire in the transformer, it's rated at 200 amp but I don't know for how long. I think this means it's not a proper one. I suspect the OC voltage wasn't high enough to drive the TIG box

Cheers Michael.

Hi Nick

Do you remember the output voltage of the welder? I have the bits you mentioned (made my own rectifier) but couldn't get it too work. I could get the TIG box to work if I plugged it into a 50 volt PSU (not a welding one). Will all TIG boxes work off AC? Never got round to trying it in case the magic smoke escaped. I often get ideas above my abilities!

Cheers Michael.

Hi Chris

If your worried about it bending can't you make a socket to fit over the spindle end and the tommy bar, bit like a starting handle but will drive both ways? En24T or a spring steel should be tough enough. I can't comment from experience but if it was my problem that is what I would be looking to do.

Cheers Michael

Hi John

My mate would disagree with you. He has a CG 125, think it has a 5 speed gearbox. He is a member of the VMCC and takes it on their runs and has lots of fun overtaking a lot of the bigger engine bikes. The camshaft only has a single lobe for inlet and exhaust valves. I believe Honda did this to make it more reliable with poor maintenance.

Cheers Michael.

Hi Wolfie

Have a look at this! **LINK**

else try Wikipedia.

Cheers Michael

Hi Sam

Isn't this exactly what JS is talking about, it didn't work straight out of the box! Worked for one guy but not another.

Cheers Michael.

"Hi,
I would just like to say that the telephone number for Rob Preston Locomotives is wrong, it is xxxxxxxxxx (UK) with an international dialling code. The e-mail address is now xxxxxxxxxxxxxx.
Kind reagrds,
xxx Preston."

Is this the kind of thing you mean Michael G.?

Just did a search on the phone number and this popped up. I'm sure if I tried harder I could get more info.

Cheers Michael

I would interpret it as Fanuc is the controller and ORAC is the lathe. Looks pretty good if you are into that sort of thing.

Cheers Michael.

Looks like an ORAC to me.

The tin cover on the crossslide and the Z Axis microswitch actuator look very familiar

Cheers Michael.

Hi Neil

Thank you for showing us a practical example of a ER40 collett chuck.

If you took one of your blanks and shrunk fit a milling cutter into it. Would this alleviate the line contact that is mentioned in the above threads?

Cheers Michael

Thanks Jimmy just added it to my wish list.

Cheers Michael.

Modified and fitted an ER 40 collet chuck to my Boxford TCL 125. It took some doing chopping the taper off the back of it and trimming down the spigot. It was good fun watching the chips burn like little fuses. The outer and inner sides had been well hardened. I think I will need to drill 3 holes in the back plate to help with the undoing of the collet nut. Tightening is ok, unscrewing is fiddly with 2 C spanners.

Hi Raymond

Glad you like a debate.

The middle picture in the **LINK**

States for tools or materials, what ever that might be. We need M.G. to dig out the patent application that would stipulate what the original intention was.

Happy debating, must get my tea and get into the garage and make or mend something!

Cheers michael

Hi Andy

How about this one made by Michael Cox **LINK**

It uses a parallelogram to get one of the 12 degrees. This means you don't have to cut a compound angle.

Cheers Michael.
