|Thread: Looking for a block of cast iron please|
To quote from the original post "a toolpost support for my Chester DB10 to replace the compound".
Could you please posit a mechanism whereby a toolpost SUPPORT will be subjected to the tensile forces you mention.
I find it of great utility to read all of the words actually written in the original post rather than to omit or imagine some.
|Thread: Greenwood Tools|
Greenwood's website is still alive and well. Details of the manufacturer (Sandvik) are given there and the insert code(s) are all there also.
|Thread: Threaded milling cutters|
I have those. I tried a 1/2" shank cutter in the 12mm one and it was a little tight. The collet did not seem much use afterwards so it might be an expensive way to work. Similarly, the 16mm one was a bit loose and it was difficult to remove the mill after welding it into place.
|Thread: Kuroda Boring & Facing head|
Everything below implies it is a clone of the Wohlhaupter UPA3...
|Thread: 5C collet chuck with integral DI-3 backplate,anyone bought one?|
But you can only use 5C in-spindle if the spindle taper will accommodate it.
If you happen to have a D1-3 with a 4 Morse taper, which is how I believe the Bantam is offered, it is too small. It is why 4 1/2 Morse was added to the range as it is the smallest that will accommodate 5C.
|Thread: Abrasive belts|
Abrasive belts are specified by width and circumference and then chosen by grit.
So if you have the machine, cut open a used belt and measure it. Or use a piece of string.
where it appears that the width is the same but the girth differs by 5mm, which might be within the adjustment range of the tensioning mechanism.
Could you kindly point me to any standard metric thread anywhere in the world that has a 2.25mm pitch.
If you are unable to fulfil the above, perhaps you could ponder on why any set of thread pitch gauges might include that pitch.
|Thread: (bicycle) thread identification?|
There is no one resource that will do that for you.
A few steps on your path to screwing utopia:
|Thread: Help needed with identifying a tool|
Would you kindly postulate a mechanism whereby the round pins on the spanner to which you refer will fit without slippage in the square or rectangular cut outs in the nut the OP shows in his photograph. Thanks.
|Thread: Chronos Wheel Engine|
Not plans, but a start...
The spelling mistake somewhat impedes the search.
|Thread: ER40 collet nut seized|
Isn't it galling when that happens?
|Thread: BA screws and nuts|
I think the website to which you are referring is
Contact details and address are given at the bottom of the page. You can compare those with the magazine advert and see if they match. The blurb also says that the company was established in 1994 so that might provide a pointer if your purchases pre-dated that. The website states more than once that you should email for a price list and that transactions should be done over the phone. It is not an online shop.
|Thread: Source of 2 inch balls for water pump|
|Thread: Involute tooth depth|
More usually referred to as d + f .
If you search for 'd + f gear' or 'whole depth of gear tooth', there is a lot of material available.
For metric gears, this one is good: https://khkgears.net/new/gear_knowledge/abcs_of_gears-b/basic_gear_terminology_calculation.html
For imperial gears (not your current challenge), this one is good: https://www.bostongear.com/-/media/Files/Literature/Brand/boston-gear/catalogs/p-1930-bg-sections/p-1930-bg_engineering-info-spur-gears.ashx
|Thread: Tailstock Die Holder (metric)|
Do you have a next-size-up-to-one-inch holder? That is perhaps infrequently used? If so, could you make a much thicker-walled shim and install it semi-permanently with Loctite? Would also need longer screws.
|Thread: Beaver VBRP Mk 1 manual / info help|
To the best of my knowledge, the manual you have is all that is available. There is no specific manual for the Mark I model. That said, a Mark II Beaver manual is more help to you than a Mark I Bridgeport manual.
There is a thread here:
where you might find information on your model.
If you type 'beaver site:model-engineer.co.uk' into Google, you will find other threads here on this subject.
Similarly, if you type 'beaver site:mig-welding.co.uk' into Google, you will find all the threads on that forum on the subject.
|Thread: 11/16 UNEF Drill size|
If you type your topic title into Google, exactly as you have written it, you will find the answer to your query.
It will also suggest you use a drill sized at 16.6 of those new-fangled continental millimetric units rather than the bizarre not-in-any-standard-range imperial number quoted above.
|Thread: ER32 collets|
Rego Fix show up to four different possibilities for the internal arrangement of ER collets. See
|Thread: ER 16 / 20 or JT2S, JT33 and JT6 Straight shank tooling|
|Thread: Colchester Bantam Mk1|
No luck or lack of proper effort?
