I added a bunch of overdrives to my wish list about a year ago when there was a "favorite overdrives" thread going, and I'm just getting around to building some of them. I haven't spent a ton of time with this yet, but so far I like it a lot. I've mostly been into lower gain sounds lately, and this definitely fits the bill for that, although it'll gain up pretty good if you crank it.

I wanted an orange LED and only had those in 3mm, so I kinda just floated it inside the 5mm plastic lens. Worked out easier than what I would have done with a 5mm. I might start doing that more often.

Always impressed by your wiring bro!

Thanks! That's nice of you to say. Turns out you're not vicious at all!

Looks great! I love those cupcake knobs.

How do you secure the LED lens to the enclosure? I picked up some like that a couple weeks ago but they are loose in the enclosure as the clips are meant to work with a thicker metal. I tried spacing them out with nylon washers but they make it difficult to install the LED. I've resorted to trusty hot glue for now..

I’ve found it pretty easy to shoot past the size I need for those, it’s in-between steps on my bit.

i tend to drill it a little bit smaller than what will fit (with a step bit), and then gently ream it with a round file until it barely fits, and then the lens just gets pushed/forced in and stays in.

Depending on the batch and supplier, I’ve had a lot of those lenses that fit perfectly in a 1/4 inch hole. I think that’s what they’re spec’d for. This one was a perfect fit and I didn’t worry about any additional retention.

Those little clips that look like they’re for much thicker material are actually intended to work with a retainer ring. Tayda used to sell them, but they cost more than the lenses and I was too cheap to buy them. I used to make my own out of some plastic tubing. Kind of a pain to cut a piece the right length, but works great.

I’ve also used glue on some loose ones. My preference is one drop of superglue right in the corner so it runs into the gap.

That's a good idea. I have to change out to an imperial step bit for these so that would save me a step. They fit ok with a 1/4" hole but can get pushed up with a moderate amount of force. I'm using this style but it's a similar application

yep, same method with that style (tayda equivalents)

i've found these are just a little bit smaller in diameter than the flatter/flush lens (seen in this build thread), so just have to be extra careful with the reaming.
