weirdoku Posted November 1, 2014 Report Share Posted November 1, 2014 (edited) Anyone? I need something made in a block of brass/aluminium or whatever solid materail about 80mm x 80mm x 30mm with 7 holes drilled in it. I need this made perfect, with the holes spaced apart from each other at a precise distance. Not looking to spend a lot, maybe including material (if you have any) about £30?

forteh Posted November 2, 2014 Report Share Posted November 2, 2014 Got a drawing? How perfect? Tolerances? Hole Sizes? I could possibly get it made in mild steel, can't guarantee it will be done on the cnc miller but it would be on the drillpress otherwise. Postage in mild steel would be about 10 quid I think as it's going to weigh 1.5kg or there abouts. Material wise, we may have an offcut of 30mm thick plate floating around, is the thickness critical as we might have some 25mm more readily available. 1 Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 2, 2014 Author Report Share Posted November 2, 2014 I'll get you a drawing done in a bit. But imagine a 80 x 80 x 30mm block with 7 holes in a line in the centre of the block. Preferably the thicker the material the better as I plan on using it as a drill guide as I don't own a drip press. It's for a guitar I'm putting together, for the string/ferrule holes so I need the spacing between the holes as straight and as accurately spaced apart as possible. Actually, thinking about it I might need to to have 14 holes... Be back in a bit with some drawings! Quote Link to comment Share on other sites More sharing options...
greg1040 Posted November 2, 2014 Report Share Posted November 2, 2014 Im a cnc miller. So could be made absolutly spot on to size. Upload a drawing of what your after. Am sure we will have some spare material at work i could pinch lol Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 2, 2014 Author Report Share Posted November 2, 2014 Greg what sort of materials have you got? What I'm ultimately after is something like THIS but a 7 hole/string version seems impossible to find. I would make one myself but I don't own a drill press to accurately drill the holes. If it's something you can I'll take you up on your offer and maybe get a few more made too. Of course I'll pay the costs etc. I'll start doing the drawings now! Thanks both of you!

greg1040 Posted November 2, 2014 Report Share Posted November 2, 2014 Im afraid only material we have is steel. Not sure if that will be any use for you. Ill machine 1 up for you free of charge should only take 15-20 mins between programming the machine ect and you can just cover postage.

dave33 Posted November 2, 2014 Report Share Posted November 2, 2014 you'd want to make it from steel and have it hardened and tempered if your using it as a guide. Quote Link to comment Share on other sites More sharing options...
forteh Posted November 2, 2014 Report Share Posted November 2, 2014 For a one off drill jig it's hardly worth the effort of heat treatment 1 Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 2, 2014 Author Report Share Posted November 2, 2014 Steel is fine, I'll just spray it or paint it to keep it from rusting. Do you want the measurements in inches or mm? Quote Link to comment Share on other sites More sharing options...
greg1040 Posted November 3, 2014 Report Share Posted November 3, 2014 Inches would be better i hate working in metric mate. Ill be back to work tomorrow so hopefully i can grab a bit of steel and make it for you during lunch. Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 3, 2014 Author Report Share Posted November 3, 2014 Ah sorry been busy last night to finish the drawing. Need to work out some more measurements in inches (I hate inches lol), I should have it done tonight. Quote Link to comment Share on other sites More sharing options...

Ill be back to work tomorrow so hopefully i can grab a bit of steel and make it for you during lunch. Interesting that you prefer imperial, is that because you're old or just dont like metric? I guess that the mill can be set to/programmed in either? I am bi-unit and can switch from one to the other quite happily, partly because my dad always worked in imperial and taught me the differences aged 8 or so. It helps that a lot of our equipment at work was designed last century and knowing the common conversions is very useful 1 Quote Link to comment Share on other sites More sharing options...

It helps that a lot of our equipment at work was designed last century and knowing the common conversions is very useful Been a cnc machinist now for 8 years and worked for 3 different companys and all my drawings i work with are imperial i get the odd drawing in metric and it just gets converted straight away. But yeh the machine when starting a new programme asks weather i want to programme in mms or inches but all the inspection equipment we have is all imperial also. Most drills and all tools i use are all metric so i can convert also of sizes off the top of my head or the good old × or ÷ by 25.4 works it out easily. But dont listen to ross im nae an auld man haha am only 24. Quote Link to comment Share on other sites More sharing options...
forteh Posted November 3, 2014 Report Share Posted November 3, 2014 Fair enough, if most of the work you have is in imperial then it's daft to convert it all over. I've had to set up dual standards in solidworks at work to cover all of our older kit that is machined to imperial jigs, does the legwork for you with fractional and decimals which is handy. Decimal feet is still a headf**k though! Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 3, 2014 Author Report Share Posted November 3, 2014 (edited) I'm soooo sorry if this gives you a headache! Sorry for my bad terminology too. I only had Google Sketchup to do this with. I'm pretty sure I got all the measurements in there. I decided to go with metric since your tools are in metric.Most important thing is that I need the distance between the middle of each holes to be as precise as you can get to 10.57mm and the centre hole in the centre.The round edge is the edge of a quadrant of a 5mm radius circle. Does that make sense? Ha. If you can't do the round edges just make them square I'll file it down myself.Pleeeeease let me know if I've missed something! And sorry for this bunch of shitty images lol. Edited November 3, 2014 by weirdoku Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 4, 2014 Author Report Share Posted November 4, 2014 Forgot to add, as well as the centre of the holes holes being spaced 10.57mm apart, if you can get them in a line as straight as possible too that'll be amazing. Thanks! Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted November 4, 2014 Report Share Posted November 4, 2014 I know this it OT but that first drawing at the top from that perspective the holes wouldnt look like that would they? Like the drawing is wrong as its implying the holes follow a curve. Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted November 4, 2014 Report Share Posted November 4, 2014 It's just with perspective included, as in drawn with a vanishing point. Other point of note in the elevation it looks like the sides aren't parallel- is that the case or is that also just perspective? Quote Link to comment Share on other sites More sharing options...
weirdoku Posted November 4, 2014 Author Report Share Posted November 4, 2014 Perspective! Sketchup has quite a bit of it. Quote Link to comment Share on other sites More sharing options...
greg1040 Posted November 5, 2014 Report Share Posted November 5, 2014 Whats the top parts rads and the bottom part corner rads im maby missing them but cant see them on the drawing? Quote Link to comment Share on other sites More sharing options...
forteh Posted November 5, 2014 Report Share Posted November 5, 2014 Bottom corner rads are 5mm, assuming the top rads are concentric they should be 7mm Quote Link to comment Share on other sites More sharing options...
greg1040 Posted November 5, 2014 Report Share Posted November 5, 2014 so thats the graphics on the machine with most of it programmed. Just gotta find some steal then i shall be good to go. 2 Quote Link to comment Share on other sites More sharing options...
greg1040 Posted November 5, 2014 Report Share Posted November 5, 2014 (edited) And a bottom view of it finished thats it all done ready to machine. If this 1 comes out ok and your happy with it i can find out cost of some alluminuim or brass for you and machine some of them also.
