Need eyelet and board building info

Post by dragonbat13 »

Since I already have a drill press, I figure I could build my own boards. I need to order board material and eyelets. I plan on ordering these things:

http://www.mouser.com/ProductDetail/Key ... %252bdL99H

https://www.mcmaster.com/#grade-g-10-ga ... ets/=40wbk

I plan on using 1/8th inch board, and dont know which type to use. I want something that is not a bear to work with and eats tools. I see that the flame retardant board is cheaper than the other type. I want to go with Blue board material although I really dont care what color it is as long as it easy to work with. Is the flame retardant board material the way to go?

Regarding the eyelets, I'm pretty sure that I have the right ones linked above for most work with 1/8th inch board. Is there a smaller size eyelet I should have on hand? I want to say I saw some builds somewhere where two different size eyelets were used. Anybody know what the "standard" size smaller eyelet is?

Thanks for the help.

I just bought the material and made my first board, I used the eyelets you have on the mouser page, but I got 1/16" inch flame retardant garolite here: https://www.mcmaster.com/#85345k31/=1926q0o

I got the blue and used that just now, it looks great if you asked me. I got 1/16" because I figured the 1/8" eyelet goes all the way through and has room to seat well with the press. It seems to be perfectly fit to me, but I'm still new to it as well. Here's the thread where I posted a pic of mine:

Get the G10/FR4 stuff, 1/8" thick. Awesome stuff, easy to work.

I figured out where I saw the smaller eyelets. They were on some relay boards, and I believe they were 3/32 of an inch. Anybody know anything about this?

I am probably gonna go with the g10/fr4. Are there any widths that mcmaster sells that are usefull? I was thinking about getting something like the 2 inch wide x1/8th inch thick material and make multiple relay and bias boards, using the 2 inch as the length dimension of the boards.

Do you think I'll have any issues using my 1/16" G10/FR4? The eyelets protrude a tiny bit out the bottom and after my staking they seem to not rotate and fit very well.

Phil, doesn't matter if the eyelets rotate or not (ideally they should not), as long as they don't fall out! Solder will fix them in place. The only trouble I've had with eyelets that are too deep for the material is that if you set them really hard, they tend to close up--the diameter of the hole gets smaller if you really smash them.

Gotcha, okay these looked really well in place to me, and don't appear to have any deformity inside the hole, I used a metal rod from one of those machinists sets with the tapered point on them (I don't even know what you call them, they came with my house), but it's at about a 60deg angle and it just seemed to expand the eyelet out enough to lock into the hole I'd drilled perfectly.

IMO using 1/8" G10 is like driving a big diesel pickup to the grocery store.

Heh. Then that 3/16" G10 I was using must be the Custom Stretch Hummer of the turret board world! Srsly, I thought I was relaxing my standards by moving down to 1/8" thick!

most of the board material I see from folks like Hoffman and Tube Depot is 1/8. But what the heck, no magic, just a long as it supports the components and you are happy with it. I built a couple of boards using the phase barrier out of 480 volt switch gear. Think that stuff was 3/16 or more.

I like the 3/32 (.093) inch thick G-10/FR-4. It's the natural greenish color, and is cheaper than the 1/8" thick, and just as strong.

Here's one supplier:

For turrets, you can't beat Keystone, who makes them solid and hollow as well as single, double, and fork-top styles. Here's my favorite turret:

Keystone has nice installation kits for use in a drill press. Make sure you get the proper swage size for your chosen turrets.

Here's a supplier that I used recently... Prices are listed in Canadian Dollars...

https://www.fingertechrobotics.com/prod ... d=garolite

I went with the 1/16" material... Thin is good and easier to tool, besides we are not building a load bearing device... It just keeps the components in place, right? Buying 1/16" also means that you get more square are for your money.

Ok so the most likely material I would order is the 1/16th G10/FR4 in the colors I want.

FWIW the eyelets for the 1/16th board should be these:
http://www.mouser.com/ProductDetail/Key ... GI%2fV9SQS

Only thing is the precut widths dont come in 1/16th sizes.

Been using one of these with the supplied diamond blade for about 4 years now... If you have one of these, doesn't matter what size sheet goods you get.

I had to put in a better saw blade in my mini table saw, the original blade sucked.
