Rick, I think you need a holiday. Get away from the snow and rain and spend a week with Jason Galbriath on the warm east coast of OZ. I'm sure he can get a range of Metal drawer sides from al cheapo to the top shelf ones.Hettich, Blum, Grass or whatever and do some playing around. I get confused myself as I am from the PVC plastic 4 fold drawers with stapled on plastic Runners era. Drawer fronts just pin them on. No worries except how long the pins are.
Its very hard to explain our issues unless you have to add these little critters.
Ok I was being sarcastic as Jason at Thermwood can't do without you. There is a program called Blum dynalog
that works out the calculations on the Blum product. Its awhile since I used it but maybe someone has it but it does show in graphic form where the drawer front holes need to be and the ramifications if carcass height is changed, the drawer number changed and the drawer side heights varied. http://www.blum.com/au/en/01/40/40/index.php
There is a free trial download.
The other issue of the drawer fronts loosing their details if drawer box changed is a real time waster and has bought many a ecabinet user to tears.
If this fails we may have to send a delegation over to Dale to show a real life demo on what happens when a client is about to sign off on a job with 20 drawers but then changes from a multitech
drawer box to a innotech
softclose drawer system. Then changes the drawer heights from being even to a big one on the bottom, mid size drawer then a 86mm on top. Then her girlfriend sitting next to her suggests that she changes the door/Drawer front style. Any guess on how long that takes?
Over to you guys. Where's my staple gun?
