Acrylic fabrication questions? I can help! - Page 7

Acrylics,
I'm trying to fix a cracked acrylic sump and need your guidance.

Here's the cracked corner ...

Here's my repair job ...

I have water tested it for three days no leaks ...

Question:
I used weld-on #4 for the repair glued from the inside ...
Now should I use weld-on #16 on the inside three seams of the three patch plates ? Or all sides of the patch plates ?

Acrylics · 04/25/2007, 09:07 PM

I wouldn't think you'd need it all around, but it wouldn't be a significant amount of extra work to do so and it *might* be better. Let it dry out *thoroughly* before adding any solvent like 16

HTH,
James

agsansoo · 04/25/2007, 09:19 PM

Thanks ...

Should I put any weld-on #16 in the other corners ?
This is why I think it cracked ... What do you think ?

H20ENG · 04/25/2007, 09:39 PM

Getting rid of those flares after bending is another great application for the 90 router jig

Did it crack from being full of water? Looks like it was dropped on the corner to me.

agsansoo · 04/25/2007, 09:57 PM

I think it was dropped durning shipping ... I noticed someting funny on on corner ... but thought it was OK ... Water tested it outside for a few days ... no leaks ... Placed it inside my cabinet. 24 hours later ... wet floors. Crack was small at first, then got bigger.

can you elaborate on this? What is it?

H20ENG · 04/25/2007, 10:07 PM

A jig that holds the router at a 90 degree angle to the table- horizontal. Then you can raise or lower it to trimt he tops of tubing, bent pieces, etc. I need to take a pic of mine- Its just old MDF.
James' is made of 1" polished acrylic

bchbum189 · 04/25/2007, 10:29 PM

yes pics are in order!

and of course james has to show everyone else up..

H20ENG · 04/25/2007, 10:54 PM

Its still covered in shavings- a sort of "acrylic camoflauge" that makes it unrecognizable

I'll have to clean it up and get pics.

Acrylics · 04/26/2007, 06:47 AM

agsansoo,
That sump should never have been shipped, period. Those flares should have been removed as Chris pointed out.
I don't know if 16 has enough "filling power" to fill it, I've never done it so cannot say. Weld-on 40 however, would be the ticket.
FWIW, if you bought this from a company - I'd definitely be calling them and make them aware. See what they'll do for you.

Chris & bchbum,
Otay, I'll post pics of on of 'em this morning when I get to the office. 1" polished...nah

I've seen several bent corner sumps and tanks from GC. Unfortunately for their unknowing customers, that's their standard craftsmanship. Perfect example of you get what you pay for.

Sorry for the rant/hijack

Looking forward to the pics of the 90Â° jig. I have a design in mind but as always, it's nice to have a guide line based on others work.

Acrylics · 04/26/2007, 10:02 AM

Hope it gives a good idea. Pls note I will take these down soon so copy the image if'n ya want.

HTH,
James

The hijack is just fine, the news is irritating to say the least

James

RichT · 04/26/2007, 10:55 AM

Thanks James. Looks great! Would you change/add anything to the design?

Acrylics · 04/26/2007, 12:57 PM

Just the set-up for dust collection. With the speed at which the shavings are tossed off, there is *alot* of static so the shavings stick to everything. Aside from that, I have no problems with it. We can machine up to about 1/4" off of 1" material with very little chatter or flex while leaving a gluable edge. These are my main priorities.

James

agsansoo · 04/26/2007, 01:29 PM

Acrylic,
Thanks !
I will try to find some weld-on #40 somewhere soon.

bchbum189 · 04/26/2007, 02:37 PM

pics are saved, i know what im building next.

James for your tables, what surface are you using? Looks like some kind of plastic.

Hey,
I just found a sheet of 50 by 96 1/2 inch plexi-g from a local dealer and he is selling it to me for $100 first is that a good price? second he said the paper is really stuck to it do you have or know a way to get the paper off if it is stuck really really well on the sheet. He is selling me a 4 oz bottle of wo#3 for $25 is that a good deal he said it is normally $45.

Thanks Ron

calvin415 · 04/27/2007, 10:12 AM

Great price on the acrylic, terrible price on the weldon...

wow I'm getting raped on the wo#3

ronn1234 · 04/27/2007, 10:30 AM

any ideas on how to get the sticky paper that is onthere off. He don't seem to think it will just peel off that is why he is selling it to me for that price

Bowman · 04/27/2007, 11:48 AM

Never tried it but it's from the same site HTH

Ronn1234,
My guess is that you could offer $50 and get the sheet, though just a guess. Distributors often write that stuff off and anything they get goes towards a pizza/beer fund. It's simply not worth the time for a company to spend a buncha hrs getting the paper off to save few dollars.
