Part 2: • How to Make a Boring H...
This is again a toolmaking project I'm working on for quite some time now. I have something in mind where I need to bore several large holes for ball bearings which have to be quite accurate. For this the tool of choice is a boring head. As I had none in my toolbox I decided to make my own one.
Due to the very limited manufacturing capabilities I have to improvise a lot to get the sometimes complicated tasks done. This meas, that everything takes a lot of time and effort. For this reason I dedided to split the boring head build video into two parts.
In the first part I am making the main body parts from 42CrMo4 toolsteel including dovetail milling and clamping mechanism. I decided against a dedicated gib strip to adjust the play between the dovetails. Instead I tried to nail the dovetail fit as close as perfect and clamp directly via one side of the dovetail. The hole for the adjustment screw took again quite some effort and time and was done in a very experimenting setup. The last part in this video is making a knurled ring which goes on top of the boring head, mostly for optical reasons and to have a good grip on the tool.
In the second part I will make the adjustment screw with it's bearing features and finish the lower body by milling, boring, reaming and finally adding the fine scales via electro etching.
I hope you find that interesting. Feel free to comment and ask your questions and suggestions below in the comment section.

Love the improvisation. The fit of your dovetails is impressive. Well done. 👏👏👍😀 Using the four jaw chuck as an improvised boring head in order to make a boring head was inspired 👌👍

@WeCanDoThatBetter 6 месяцев назад

Thank you very much for your kind feedback! Yes, you can use the four jaw chuck as a boring head, but I wanted a real boring head which makes working with a lot easier. But the new boring head will be used on the lathe as well :)

@whiskers97 6 месяцев назад

hey love the video as usual. The stuff you make is always great. One tip i would like to give you is when you set the stop on your bandsaw, after you get the material clamped in the saw at the length youre wanting usuing the stop, i would back the stop away for the cut so that the saw blade doesnt catch as hard on the material and slam it into the saw. Just a tip, everything else is great tho.

@Shopaddict23250 6 месяцев назад

It's a good idea to back off on the depth stop once the cut has started on your bandsaw and certainly before it breaks through, might save your blade if the cut off work jams, just sayin'.

@WeCanDoThatBetter 6 месяцев назад

Thanks for your kind feedback and tip. I have to do it the way you said next time.

@tazthedevil22 6 месяцев назад

We always put a piece of material between the part you cut off and the stop. This piece was a exact length (100mm I believe) and removed it once the material was clamped. That way it was still easy to have parts cut the same length, but you still protect the blade.

@Self_Evident 6 месяцев назад

@@WeCanDoThatBetter Yea, that does sound like a good idea... ;)

@bobweiram6321 6 месяцев назад

⁠⁠@@tazthedevil22 A bandsaw blade's kerf width is rarely accurate or precise. The set of the teeth can vary widely not only from blade to blade, but from tooth to tooth. Even temperature, hardness of the material being cut, and wear have an effect on it. Your best bet is to slightly oversize and mill down to final dimension.

@unacceptableminority7101 6 месяцев назад

When cutting dovetails end mill first is cool but you should definitely do the slitting saw operation before using the dovetail. All the strain from the 45 deg cutter is at the tip because there is nowhere for the chips to go. So adding that space at the tip will prolong your cutter and you can cut faster.

@WeCanDoThatBetter 6 месяцев назад

That was exactly what I thought while editing the video. I think doing the undercut first would have made milling the dovetails way easier. Thanks for your advice.

@bamoblivion8614 5 месяцев назад

@WeCanDoThatBetter 5 месяцев назад

Thanks for your comment. You mean an automatic facing head? That would be great. I actually thought about that. It's at least two numbers more complicated and I think no one on RU-vid has really done it from scratch. So perhaps I will try some day.

@1crazypj Месяц назад

Maybe drilling, sawing and 'hitting things with hammers' was way slower than milling, but, hitting things with hammers is good for you. Very satisfying result when necessary 😁 I watched part two first but had to watch part one to see exactly what you did. Knurled ring was a good idea. It does look good and I'm sure it has practical use, my 50mm boring head (bought, Chinese) could do with same Not sure if it would be possible to make knurl in Cr-Mo without a cut knurling tool as it's damn tough stuff Reading the description for material and why you did things was most informative, I don't always expand the text to read it, I guess I should.

16:50 Have you considered some soft jaws for your vice? Maybe a set of copper ones like your lathe chuck, or some leather ones for softer metals... None the less, you do beautiful work.

@ThePottingShedWorkshop 5 месяцев назад

Was that a carbide slitting saw used near the start of the video. If so, lucky you having such tooling. If HSS, you're running it too fast! You should not have sparks from HSS tooling. Looks like you're running the dovetail cutter too fast too!

@WeCanDoThatBetter 5 месяцев назад

Hi and thanks for the comment! It is a carbide saw blade I'm using here. It is from Proxxon, a 50mm carbide saw blade with 1,1mm width. This one is pretty affordable as it is not fully carbide, only the cutting edges are carbide. I don't know why it sparked while cutting. Perhaps it is just dull I guess. The 0,5mm saw blade I used later in the video for the clamping cut is from solid carbide and pretty expensive.

@greglaroche1753 Месяц назад

I'm looking into adding bushings for my the spindle of my chinese drill press. So that the spindle doesn't slide directly in the casting bores? Any tips from you? Any chance I'de get a matching internal 40 mm diameter cylinder off the shelf somehow? I'm intending to enlarge the casting bores by hand.

@jcp007 6 месяцев назад

Why not knurling the body instead of machining off lots of material and then adding back a ring?

@WeCanDoThatBetter 6 месяцев назад

That is actually a very good question. Not really sure. Perhaps becaus it is easier to lapp the shaft to final size when the last millimeters get covered by another part. Lapping directly against a shoulder is very difficult.
