Hi David - Sure I can. I bought a small vacuum pump - I can't find where I bought it from - but there are oodles available and they are cheap - less than $200 - and you only need a very small one. I have custom sized bags made by these folks - I also use their Unibond 800 adhesive for laminating (two-part urea formaldehyde): http://www.vacupress.com/products.htm Here's a picture of a large bag and the pump - that's all there is to it - very simple, and you can roll the bag up for storage (I'm gluing up a laminated soundboard panel in this photo): The bag below is smaller and I use it for pinblocks and rib slabs - pictured are two rib slabs being glued up: And then, of course, there is the REALLY high-tech method involving clamps - but it's too complex to describe here - besides, it's proprietary..... : Terry Farrell On Feb 18, 2010, at 12:06 AM, David Love wrote: > Terry: > > Can you elaborate on the vacuum bag set up that you employ? > > David Love > www.davidlovepianos.com > > From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] > On Behalf Of Terry Farrell > Sent: Wednesday, February 17, 2010 8:48 PM > To: pianotech at ptg.org > Subject: Re: [pianotech] Fwd: Hybrid pinblocks > > Dale Erwin wrote: > "I went to the trouble of making an air hose press to do the glue up." > > Dale, Dale, Dale - VACUUM!!!!!!
