i will go for the pemmican, ginger beer and cat any day

[grendel]

I suppose here is a better place to put this rather than carry on drifting the Broadsman thread

Today I cut a test in Brass (thin brass because I have a ton of that), so both parts were tested side by side, the test was successful, so the real thing is whirring away in the background now.

 

[grendel]

Add another job to the list Griff, though this is a quick one that just involves a few seconds and a couple of screws, fixing builders badge on bulkhead.

[BroadAmbition]

Oh Wow, look at that.  Only been waiting for one of these since 2002 when we adopted R641, that's twenty years now.  All good things come to those that wait. 

Are you painting the background in black or am I?

Just asking as I'll need to source handy sized brushes and some black enamel

I think we'll give you the honour of screwing it in place with photographs for our records.  Therefore it can stay off the list

Griff

[grendel]

I have brushes, but not black enamel, I can probably source some, so I can do it if you wish. (unless you want the fun)

[BroadAmbition]

Its not the fun. its having the time whilst in AMP

Your choice - Either you have the fun, bring it with you ready to fasten in place, or post it to me and I'll endeavour to get it done prior to the 15th

Cheers,

Griff

Just spray it all black then with fine sand paper on a firm backing rub over the lettering.

Brass letters on a black background.

Longest part of thw job,waiting 24 hours for the paint to harden.

That looks really cool grendel well done, you may of opened a can of worms here. I can see orders being placed lol..very smart indeed.

[grendel]

Well the final product has been produced, at a cost mind, I broke 3no 1.5mm end mills/ engraving bits making this, cutting it out broke 2, as it is 3 mm thick, it's quite a difficult cut down in that pocket, as it was I think the bit pushed up into the collet as I cut 3.2mm deep and then found it was 0.5mm shallow, so this morning some cleanup was done.

I so very nearly did it again as I found once I had finished, that I had engraved the back upside down, but then I rationalised that you would never look at both sides at once, so left it, I have black enamel on order, so I will do the paint job Griff.

Whether I post it to you or bring it up with me may well depend on how the boats are scheduled for maintenance, as soon as I know, I can work it out.

[grendel]

The casualties, these bits have cutting tips only 1.5mm wide (1/16") , actually on the engraving bit the tip is just 0.05"(1.2mm) cutting edge, and that was used to cut out the design and do the letters on the back. In the picture, the cutting edges are gone because that's what broke off, the shafts on these are 3mm.

[Smoggy]

Do you use any lube with it Mr.G?

The cutters I mean...

[grendel]

I dont, and shouldnt really need to with brass, if I used lubrication, that would reduce chip clearance and that is paramount with these machines and small bits

[grendel]

this is the test piece that i did in thinner brass, I found I had some black modelling acrylics, so thought I would try out the test piece, it worked, a quick coat of paint and three hours later a rub across some 400 grit wet and dry on a flat background, brought up the brasswork a treat, the real deal will get done in enamel and baked for good adhesion (into the oven on low- this is when its good not to have an other half to complain at this point, I know some guys that have to have their own old oven in the workshop for these processes).

anyway pleased to say this approach is quick, and works, remember this is just the test subject.

[ExSurveyor]

I would be happy to achieve that as a final version 😁

[grendel]

to be honest I am always happy if a test piece ends up at a good quality, as that shows I have my processes correct.

[FairTmiddlin]

Good engineering Grendel

Any machinist would be proud of that.

[ChrisB]

How do you arrive at your "Speed and Feed" settings or does your kit do that for you?

Only asking as the process has bu€ge$d three tools.

[MargeandParge]

A rod for your own back how do you make a model sized version.? What you have done is amazing and you should be proud of it. Kindest regards Marge and Parge

I have a spreadsheet that gives safe speeds and feeds, the real issue was the deep cut round the outside 1.5mm wide 3mm deep, the cutters are being pushed to their limit (or beyond, and they are only small cutters.) the problem was the holes, if I compensated for the cut round the outside, the cutter would have been too wide to do the holes.

Just out of interest, what ever happened to Jack powels hire fleet. Its seemed very busy, I had a few years away from the broads and I remember being surprised they'd disappeared. A fair size fleet as well if I remember correctly.

They were swallowed up into the Pennants holiday group along with Earnest Collins, Hearts, Southgates & Herbert Woods in the 80’s.  When they went pop the boats were sold off, a few stayed with Herbert Woods for a few years but all gone now.

I have the CNC file, so I just scale it to 1/12 size- Like this, a bit of cleanup required, and I nearly lost the part when it flew out of the workpiece when the mill cut through.
