Thread: Your latest project

RC,
That looks like a fair dinkum centre drill.

Today I decided to try and get my Chinese multitool linisher attachment going properly.

I bought it last year but never could get the belt tracking right no matter what, eventually the belt gave way.

Earlier during the year I bought some decent belts for it, same thing was happening so decided to just forget about it for awhile.

So today decided to check the wheels to see how parallel they are to each other, way out and a square against the bracket that attaches to the grinder shows this.

So clamped the bracket to a solid surface and it was were it should be.

The platen also needed some straightening.

So put it all back together and still pretty much the same issue.

So did a bit of googleing and it seems the front drive wheel needs to be crowned slightly, it made sense seeing that I had seen belt Sanders with crowned wheels in the past.

So I still had the old disintegrated belt that was now about 10mm wide which I attached to the multitool and while it was powered up took a file to each end to slightly crown.

It now works as it should and the belt stays perfectly on the wheels.

It is a little noisy, but I guess that is how they are, the noise goes away with the belt removed.

Gotta love Chinese quality control.

Not sure if your up to speed with tools but that is a Morse taper twist drill not a centre drill.

As another member asked 'What's it like to be back in a real shed?' Absolutely wonderful

I'm still getting my hand back in and the brain back in gear, but I've been catching up on miscellaneous jobs before getting into the really tricky stuff.
One such job was an adaptor. Before going to Tas I made an adaptor for the small mill that I bought so that I could use a Kaiser boring head in it. Packing up, I advertised the adaptor on eBay but did not get any takers so gave it away to someone I met in case they ever got a Kaiser. However, Ebay relisted automatically and on the 5th or 6th relist, it was bought by a guy (Paul) in the US.
Couldn't sell what I did not have, so I made another for him. However, he had a Aceria mill that took a Schaublin W20 collet. Did I know where he could get an adaptor?
Talked with Bob and the answer was no - not really. Any W20 to Morse adaptors were for tanged tools, so sideways forces would cause problems (for boring, maybe caused by an interrupted cut?)

Looking at the information I could find and doing some sketches, MT2 would just fit in a B type sleeve. Complications were a 45/5 buttress thread, major diameter 19.7mm on a 1.666mm pitch. Normally I have a mating part to use as a gauge but this time was all measurement.
The tool was ground on the surface grinder using a 45 degree jig and then another jig jury rigged to get the 5 degrees on the other side. Included angle of 50 degrees which I checked with a protractor, so good for that bit.

The pitch was an odd one. My lathe is imperial so I first looked for a tpi equivalent but that was 15.246... tpi, so no good there. Finally I twigged that if I used an appropriate ratio I could set the lathe on 16tpi and go from there. Luckily I'd made up a set of change gears when doing Simon's worm all those years ago, so put the couple together and managed to get the right pitch (the gear couple is 41/43 as installed on the banjo)

Cutting was pretty standard although at times I did not know whether it was good or bad. I ended up cutting a thread, removing it and checking under the microscope for pitch and land width, and then making another.

Below are the adaptor, and assembled with the Kaiser adaptor. Missing are a keyway and M10 SHCS to hold it all together but I was in a rush (going away) and Paul said he was happy to sort those bits, so all good.

Takes up a bit of Z and if I were doing it again, I'd probably try making it as one - Kaiser StP straight to W20 which would probably save 20 or 30mm, but I did not realise that the mill was W20 until after the Kaiser piece was made.

Very nicely done Michael, and it speaks volumes for the kind of person you are that you have taken the time to make a custom part to fulfil your part of the deal. Most would have just apologised and refunded the buyer. You have gone the extra mile and made good your oversight, so that the purchaser did not end up disappointed with a "no deal". Very well done.

pipeclay,
I really enjoy your sense of humor.
Bob

Well done Michael,

Custom making a part for a person purely to satisfy an ebay sale and an honest mistake is as Rope stated, a very generous and kind gesture.

I'm glad that gear you made came in handy for another use! Reading between the lines in your above post, are you back home in S.A. for good now?

I hope so. While Tasmania is nice, it was not home.

Michael

Absolutely. Tassie is a lovely place. BUT home is home.

Im happy for you to be back. Being back at home and in your shed must be like a big warm hug!

Welcome home Michael.

I had the opposite reaction after leaving Sydney for here. I like visiting in Sydney but I think hell will freeze over before I ever moved back to live.

PDW

I was born in Melbourne but some time back I moved to Sydney for work. Stayed there for 3 years and eventhough I loved the time I spent there, I always considered Melbourne my home.

I guess never say never but I will never live in Sydney again. I love where I live now.

I have done lots of travelling around Australia but I always love coming home.

Edit: Actually my wife and I both agree that it would not take much for us to move to Tassie......

Dunno why anyone would want to live outside Queensland. Although it got ruined by all the Mexicans coming up and bringing their ways with them.

Queensland Govt pays me to come up there. However, they don't pay anywhere near *enough* to get me there in summer.

The only habitable bits of Australia are the SE corner from say Bermagui to Warnambool and the NW corner from Margaret River to a bit east of Esperance.

Might that be the SW corner rather than the NW corner?

Yeah - bloody typos.

Kimberley country is certainly interesting - I've sailed the entire north coastline from Weipa to Port Hedland back in the 80's.

No way I'd want to live there, though. Must go back to Borroloola one of these days just to see if it's changed for the better. Can't conceive that it could change for the worse.
