Small boring head

[Swifty]

Hi Paul,


Gus will take you out for a spin and beers.And if the fish will bite,we will fish for dinner.No worries.We won't get lost. I have Chartplotter and AutoPilot.The inland sea is very calm.No storms.
Where about you live? My daughter lives in Glenhuntly. Nellie and Gus would drop by now n then to see the two grandchildren before grow too big and tall.

Hi Gus, I live about 45 minutes south of your daughter in Mount Martha. Had a boat years ago and fished Port Philip Bay often. A large, relatively shallow, bay that commanded respect if the weather suddenly turned. A long way back in if it was rough, so had a rule no beer until safely back, you needed your wits about you to battle the weather.

These days I mainly stick to fly fishing rivers.

Paul.

The method you used Gus for calibrating the dial is one I have frequently suggested. However, I have always suggested using a strip from a sheet of adhesive paper as used when making large self adhesive labels using a computer printer. Sometimes, if the chuck or faceplate is the slightest greasy it will not adhere sufficiently so I particularly like the elastic band idea, will definitely remember it for the future.

You mention a rotary table of mine, do you mean the one here http://www.homews.co.uk/page462.html

If so, then this was specificaly designed to satisfy a promise I had made to the Projects in Metal web site and can be found on their website here
http://www.projectsinmetal.com/a-simple-rotary-table-without-a-worm-drive/

It includes both the drawings and the proposed method of manufacture.

I have not published it in any of my books, but have now made it available to the Model Engineers' Workshop magzine and is to be published in the 200th edition which will be out in a few weeks time.

Hi Harold,

Thanks for the support. You have just replaced my former idol and hero-----the real/late "Tubal Cain" You are now my new idol and hero in DIY machineshop tools. The USA TubalCain is quite good and I follow his YouTube Videos for exposure.
Thanks for link to the Rotary Table. Now that I have the Boring Head which will help in machining other tools. If Harold drops by Singapore,Gus will buy beer and lunch and dinner for my Guru.

I get to hear about the Red Snappers and the bad storms in Port Phillip Bay.
Sad to hear that when the fish are biting and a storm is coming,some folks especially the new arrrivals risked their lifes over fish.

Went fishing off the East Coast of Malaysia and got caught in three successive
Sumatra Storms.Fortunately you can see it coming like a black curtain. The Albin 28 is a good boat for such weather. The inland sea of Singapore is very calm.No worries. Still struggling with the fly rod casting. Might go for classes.
See you.

Best Regards,

Gus

Hi Harold,

Would also love to build the RT with worm drive and divider plates.Plan to go into gear cutting,tooth by tooth.

Your caution is not shared by others because there are quite a few empties lying on the bottom and are a favourite hiding place of the nasty little blue ring octopus.

I just went thru your book on "Dividing" and saw your paper band which was more neatly done than mine. Need to make some dividing plates for gear cutting and was wondering how to divide 100----150 holes.Been racking my brains for some time.
Will be test boring tomorrow. Will post.
Thanks for sharing trade secrets with us.

Sorry Gus for the delay but other forums and other tasks have been taking up much of my time.

First, a big thanks for the offer, but we have never been globe trotters and am now at an age where it is too late to start.

With regard to the points you have commented on, starting on the easier one, to discuss that is.

Making a dividing plate with a large number of holes, typically 100, if using the paper strip method there will be nominally lines spaced at 3mm if on a 100mm face plate. If making a low load, low speed gear the accuracy should be adequate, but of course the system becomes more suspect the greater the number of divisions to be made.

An alternative is to using the paper strip method, working out the X and Y coordinates for the holes and producing the division plate on the milling machine using the values can be cosidered. This should be more accurate.
Working out the values can be quite a task unless one is into using spread sheets or has a programable calculator.

If you have a particular large number to divide I could possibly work out the coordinates for you as I have it programmed and only takes a minute or so to set up and a split second for the results to appear. I could convey the results using another website that I use. For this do contact me using the contact page on my website.

My web page regarding holes on a PCD is here
http://www.homews.co.uk/page400.html

If wishing to screw cut a worm gear the resulting pitch/TPI will almost certainly be a complex number. Rather than go into detail here the subject is covered on my website here
http://www.homews.co.uk/page362.html

I have a page on my website that lists all the pitches possible using any of the combinations (over 66.000) using 13 Gears(I think that is the number) This is ideal for the complex values that are required when cutting a worm or metric threads on an imperial lathe. Also simple values where the user has only an incomplete set of changewheels. The pages are here
http://www.homews.co.uk/page28.html

Should anyone be reading this and learn of my website for the first time a good place to start is at the index for the metalworking section. This is here
http://www.homews.co.uk/page463.html

Hope this helps Gus.

Hi Harold.

Thanks for the info.
Heading to TokyuHands,Osaka,Japan for a great time windowshopping for tools.
Imported Chinese tools of higher quality sold here is cheaper than the Japanese made.
Will be buying some mini worm and wheels to make mini dividing heads.
