Infusion Plan

Jorge, you can get circular saws which have vacuum ports on the blade shroud. Connect a vacuum cleaner and it makes virtually no mess at all. Use the correct blade, and it slices through sandwich panels like butter. It really is very painless ...

 

Yeah I need to get one of those, I am pretty sensitized to dust and chemicles after 20 years of construction.

 

Ok you guys win ... I dismantled the part, bag was too difficult to make. Will infuse it as panels tomorrow. Thanks!

 

Lmao!

Next boat I build, I foresee a bunch of flat panels, all infused one on top of the other, seperated by perf film, under a single bag, in a single 50gal resin shot....

 

If I could weld a bag up the idea would have worked but it would require creating a tool for the bag construction ... i may play with bag construction but for now I need this boat it thewater!

I Like that idea... All the time setting up and breaking down eliminated plus save a ton of consumables. I would be tempted to use a flow media on each layer and feed them independently but I bet with the perf'd core you could do a pretty high stack just with release film like you say.

 

Should not be required... The flow occurs in all directions. The z direction is a short distance in comparison...

Perimeter feed around the bottom with full flow media, single vac line in the top center of the stack... It quite simply has to work I reckon

 

I have 4 small panels I can try it on, infusing the base today.

 

Go for it... I would have done it already but I don't need anymore panels for my boat, I've already made all I need to finish it. Have been wanting to try a small stack like this for quite some time to simply prove the idea but havnt had the reason to just yet...

 

Ok, I will post pics of what happens, thanks!

 

Hi - I agree with you both on this one. Haven't done it yet but it was a logical step last time I was doing lots of flat panel work in which the panels did not need a moulded surface. I'm sure you could do quite a high stack with a perimeter feed and it would fill easily. I played with making tooling board this way and was infusing MDF dust (recovered from varous timber sellers around here) 100mm thick at one time from the bottom up. So I think the panels you are talking about will be easy. Get a high flow perf, you want one with at least 2%+ porosity... Some of the hole patterns and hole sizes do not indicate they have high porosity.... It would be good if they speced it quoting porosity so they are easy to compare. Peter

 

Infused the base but came away thinking that maybe I should test on a scrap part before infusing as a stack, it seems like it was wetting out pretty slow but could be just that I am used to seeing a resin front ))

Very cool the way perf'd core infuses … though little nervous first 4 minutes when you don't see anything happening!! Was a perfect bag, no air got in at all that I could see.

Jorge - I think you have graduated as a VIP laminator, well done. Peter S

 

LOL, thanks man, between you and groper had good teachers!!

 

Feb 2012 till August 2014. 1.5 years not a bad journey... a beautiful thing... Peter S

 

pretty cool,flow media on the bottom,i'll have to try that.Edges are just rounded over?Glass wrapped around?

Thanks for takin the time Jorge.
