patching holes in mdf?

[scoob8000 10+ year member]

half an inch is a little big for any kind of glue or putty.

Grab a 1/2" wood dowel from Home Depot or Lowes, cut a couple pieces .75 thick (or whatever thickness MDF you used) and glue them in the holes..

[edit]

With a hole that size, I would not use sawdust and glue mix. Instead, get a dowel pin the same size diameter as the hole, cover it in glue, shove it in. When the glue is dried, trim off the excess of the dowel. Best way to do it IMO.

You beat me to it! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I was going to say fiberglass, but cutting out a circle and sticking it in there is easier...

dowel rod seems legit

can i expect a 1/2 inch dowel to go into a 1/2 inch hole, or will i need to take it a 1/64 or 1/32 or something bigger? just wanting to make one trip out to lowes as cold as it is right now, and i don't have drill bits that big other than my 1/2 inch.

I filled holes with just a basic two part 5 minute epoxy. Most are good on wood, metal, etc. Cover the hole from the inside to keep the epoxy in the hole so it doesn't leak down while it cures.

lay a piece of paper over the hole and rub it with a crayon or pencil, take the tracing with you.

Maybe a short bolt/washer/nut could be another (temproary) option..

local hardware store has them..at my resturant we poured epoxy on the bar so it had this clear finish coat on it like a big thick layer of sealer....sec i'l get u a nice link but ur local stores always have this ...even walmart http://www.aplusbputty.com/applications.htm

e-poxy>all glues

Overkill

mdf/sawdust or LN will work fine

is it sealed or ported?>???

they're all ported. here's some pics of my new box, for your viewing pleasure. tommyk90 designed it, bj fisher built it. it should make some noise //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i'm a sucker for bare mdf and rounded edges //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

^^^ X4 Dowel.

even if you have an old broom stick lying around, just cut/sand it to fit and wood glue it in.

You could also use a nut and bolt with some rubber washers, like a toilet tank to bowl kit.

Kinda ghetto way about it, but its an option.

He wants it to look good


Doesn't bond to the wood

Wouldn't cover the hole on the outside, again he wants it to look good

You fail, liquid nails sucks

right

that is a really nice boc. i like the way u did the double baffle. my next box will probably be like that. but just do like the other guy said and mx the sawdust and glue together and fill the hole. ive never thought of it.

i'm using the dowells and blue to plug the holes. not in this box, but my last 2 that were mounted using the same holes as this one has.
