Hi Lads
Being at a bit of a loose end this afternoon i thought i would make a start on a tapping tool ,,,, giving it a bit thought i decided instead of making the complete tool i would make an attachment to fit my new ped/drill as it has a good stiff column and large table ,,, this way i would save on shop space , material and time :med:
The design so far , going to be a welded up job :dremel:

It will fit here, between the collar and head casting and can be swung out of the way when not required

Selection of mystery metal for the job :)

A bit of ruff machining to size and welding :dremel:

I still have to make and weld in the webs

When i have it all welded up i will stick it in the furnace for a bit of stress relieving ,, then machine it up proper :dremel:

Very nice Rob.

I was going to ask about it being square and perpendicular, but I think you answered it for me.
What did you weld it with?
Eric
-
Nice one!
but does it not interfere with the table rack on the support column ?
I did wonder how you would keep the two bored bushes parallel, but see at the end you had allowed for it, with stress relief then finish boring.
I am a great believer where possible to prefab with the welder, I like welding as well as turning.
As I said nice one, many thanks for the pics. :nrocks:

Hi Eric :thumbup:
Just zapped it with my MIG welder :zap: :dremel: .

Hi Rob
Nice idea.. would it not be easier to make a two-piece clamp? No need to dismantle the drill M/C. Or have you discounted that idea ?
I notice some clumsy oaf has poked holes in the cross-vice.... :lol:

Very nice :bow: :bow: :bow: :bow:
That weld looks a bit pourous :D :D :D :D :D :lol: :lol: :lol: :lol: :lol:

Take no notice of them, i would have tacked it to the table :headbang:
-
Crikey.. do you think it will be sturdy enough, Rob? Looks like a con-rod for the QE-2!
Guess it will be okay if you are only tapping small holes, like 1"-8 tpi. If it's not stout enough
you could always put a platter on it for a swing-out hors d oeuvres server.
:lol:
You go, Mister! (and I didn't see no stinkin' holes..)

What did you weld it with?
Eric
Chewing gum by the looks of it.......................

Looking good so far Rob :thumbup:

Thought it was still under engineered for 14 BA so i welded some extra bits on :lol: :lol:

it can stay there for now,,,,, until tomorrow to cool down slowly and normalize stress relief :coffee:
Rob

That is coming out very nice!
-
:D :D Great going Rob :bow: :bow:
:beer: Good to see you got the shop defrosted enough to get back in there :thumbup:
:ddb: :ddb: With the furnace started, things should heat up a whole lot more :lol: :lol: :lol:
:poke: :poke: Are you going to beef up the ped/drill's column and base to cope with the forces of those 14BAs ? :doh: :lol: :lol: :lol: :lol:
Cracking job as usual mate :thumbup: :bow: :bow: :bow:
Kind regards, Arnold

It would be a good idea to make 2
One for each side to stop it from tipping over :D :D :D :D :D :D
-
oh...all de funny mens....... mate, looks great.... if a tad over engineered.... jesus bloke! How large are ya gonna tap? :doh:
As always the stuff coming R W Engine Works is first rate.... you do keep the bar right up there fella.... great work.... :thumbup:
-
Looks like it's going to be a really useful piece of kit. The arm is pretty long, and the beefiness will certainly give it rigidity. So, unlike many puny tapping stands, you will be able to tap holes a long way in from the edge of the material. Great job.
Andy

Looks spot on Rob. Could you explain why it goes in to the furnace?
-
Top notch engineering Rob! :thumbup:
Can you bring a little of that heat down here, for my shop? Getting just a little bored with looking at wallpaper/ tele etc..... :bang:

Hi Chris
The part was stuck in the furnace so that i could get rid of any internal stresses in the welded part that may have built up due to welding.
Over time the internal stresses can cause the part to move ,, they can also come out when machining operations are carried out .Just like when you machine more off one side of length of bright mild steel flat bar
So it was placed in the furnace brought up to heat and left to soak a heat for 1/2 an hour (rule of thumb for soak time is 1 hour per inch of thickness ) then left to cool down very slowly . :med: :med:

Hi Lads ,,,,,,,,,,,, :lol: :lol: :lol: :lol: :lol: your comments are killing me :lol: :lol: :lol: :lol: :lol: :beer:
Well its cooled down now and i have given it a quick blast to remove the black scale ,, some shots of it clean with a couple of every day shop tools in for scale ::)

I will start machining it the morn (tomorrow)
David : furnace is to well insulated ,,, you have to get in it to feel the heat :D

Nice one Rob - thanks for the info, I didn`t know any of that!

Hi Rob,
I noticed your 3d Model at the beginning of your Topic. Which CAD package did you use, I was wondering? Regards, Paul
-
Hi Paul :wave:
The 3D model was done in Solidworks :dremel:
Been a bit slow in the shop over the past few days ,not allot done ,, mounted the arm to the mill table ,,, making sure that it was nice and level and making sure it was clamped evenly , so that it was not distorted by the clamping ,,,that would be no good as when the clamping force was removed the bores would come out all to cock .

facing the underside so that its square to the bore

Well done Rob :clap: :clap: ; Glad you got some shop time :thumbup:

....I'll have to get or make myself some of those (01-10-11)2 blocks; they seem right nifty for a clamp-down!

I think I need to build something like this one day, but when I do, I'm not going to fiddle about with one of
these puny jobs like you're showing us here, Rob. I wanna be able to sit on it, too.
I can see i am not going to here the last about the size of this thing
Rob
No, s'pose not!

Rob please explain how you faced the edge with a boring tool???
Or am I just misunderstanding?
Gerhard
-
:lol: :lol: :lol: Hi Dean :lol: :lol: :doh:
Hi Gerhard
No your not missing something ,,, i should have said the i used a boring and facing head to do the job :doh: , my B/H has the capability to face off the job , cut grooves and do under cutting and tapered bores :dremel:
You attach a bar to the feed ring witch you keep hold of and the head feeds in/out until it hits the stop , witch cuts the feed ,, also fitted with rapid return :)

Hi Lads
Grabbed a bit of shop time today :ddb: :ddb: here is were i am up to , split the large end and drilled and tapped :dremel:

I still have to make a bushing for the small end and the rest of the attachments :dremel:

Nice Job Rob :thumbup: - yes; "industrial" should cover it...
You're in a bit of a sticky position now... What colour are you going to paint it ? - I know you have gray, but on a green DP :poke: ? :lol:

Bulletproof is how I'd put it, Rob. Looks great!

Good job you've done on that Rob W :clap:, very robust :bugeye: lovely welds :bow: :bow:

Rob,
Silly question but why not lift the table off, make a bushing for where the table spigot goes and use that arm, put the vise on the base table ? Don't apply now as you have made it but others could do this without making a new arm when most bench drills already have one

Hi Rob,
I’m not sure if you already have a chuck to use in your tapping attachment. If not, you might be interested in the cunning geometry of this type: http://mikesworkshop.weebly.com/improved-chuck-for-taps.html
Of course, things might have to be scaled down a bit to fit your dainty attachment :lol:
